PROSPECTUS SUPPLEMENT

(To prospectus dated March 27, 2020)

10,000,000 Shares

5.75% Series A Mandatory Convertible Preferred Stock

ViacomCBS Inc. is offering 10,000,000 shares of its 5.75% Series A Mandatory Convertible Preferred Stock, par value $0.001 per share (the “Mandatory Convertible Preferred Stock”).

Dividends on the Mandatory Convertible Preferred Stock will be payable on a cumulative basis when, as and if declared by our board of directors, or an authorized committee of our board of directors, at an annual rate of 5.75% of the liquidation preference of $100.00 per share. We may pay declared dividends in cash or, subject to certain limitations, in shares of our Class B common stock, par value $0.001 per share (the “Class B common stock”), or in any combination of cash and shares of our Class B common stock on January 1, April 1, July 1 and October 1 of each year, commencing on July 1, 2021 and ending on, and including, April 1, 2024. Each share of the Mandatory Convertible Preferred Stock has a liquidation preference of $100.00.

Unless earlier converted, each share of the Mandatory Convertible Preferred Stock will automatically and mandatorily convert on the second business day immediately following the last Trading Day (as defined herein) of the Settlement Period (as defined herein) into between 1.0013 and 1.1765 shares of our Class B common stock (respectively, the “Minimum Conversion Rate” and “Maximum Conversion Rate”), each subject to anti-dilution adjustments as described herein. The number of shares of our Class B common stock issuable on conversion of the Mandatory Convertible Preferred Stock will be determined based on the Average VWAP (as defined herein) per share of our Class B common stock over the 20 consecutive Trading Day period (the “Settlement Period”) commencing on, and including, the 21st Scheduled Trading Day (as defined herein) immediately preceding April 1, 2024. At any time prior to April 1, 2024, holders may elect to convert each share of the Mandatory Convertible Preferred Stock into shares of Class B common stock at the Minimum Conversion Rate of 1.0013 shares of our Class B common stock per share of the Mandatory Convertible Preferred Stock. If you elect to convert any shares of the Mandatory Convertible Preferred Stock during a specified period beginning on the effective date of a Fundamental Change (as defined herein), such shares of the Mandatory Convertible Preferred Stock will be converted into shares of our Class B common stock at the Fundamental Change Conversion Rate (as defined herein), and you will also be entitled to receive a Fundamental Change Dividend Make-whole Amount and Accumulated Dividend Amount (each as defined herein).

Concurrently with this offering, we are also offering 20,000,000 shares of our Class B common stock (the “Concurrent Offering”) pursuant to a separate prospectus supplement. The last reported sale price of our Class B common stock on The Nasdaq Global Select Market on March 23, 2021 was $91.25 per share. We have also granted the underwriters of the Concurrent Offering a 30-day option to purchase up to 3,000,000 additional shares of our Class B common stock. Neither the completion of this offering nor of the Concurrent Offering is contingent on the completion of the other, so it is possible that this offering occurs and the Concurrent Offering does not occur, and vice versa. We cannot assure you that the Concurrent Offering will be completed on the terms described herein, or at all. The Concurrent Offering is being made pursuant to a separate prospectus supplement and accompanying prospectus, and nothing contained herein shall constitute an offer to sell or a solicitation of an offer to buy shares of our Class B common stock to be issued in the Concurrent Offering.

Prior to this offering, there has been no public market for the Mandatory Convertible Preferred Stock. We intend to apply to list the Mandatory Convertible Preferred Stock on The Nasdaq Global Select Market under the symbol “VIACP.” Our Class B common stock is listed on The Nasdaq Global Select Market under the symbol “VIAC.”

Investing in our Mandatory Convertible Preferred Stock involves risks. See the risks described in the “Risk Factors” section beginning on page S-13 of this prospectus supplement and in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (our “2020 Form 10-K”) filed with the Securities and Exchange Commission (the “SEC”) before investing in any of our securities.

We have granted the underwriters the option to purchase up to 1,500,000 additional shares of Mandatory Convertible Preferred Stock from us at the public offering price less the underwriting discounts within 30 days from the date of this prospectus supplement, solely to cover overallotments, if any.

Neither the SEC nor any state securities commission has approved or disapproved of the securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the shares of the Mandatory Convertible Preferred Stock to purchasers against payment therefor in New York, New York on March 26, 2021.

NOTICE TO INVESTORS IN THE EUROPEAN ECONOMIC AREA

This prospectus supplement has been prepared on the basis that any offer of securities in any Member State of the European Economic Area (“EEA”) will be made pursuant to an exemption under Regulation (EU) 2017/1129 (the “Prospectus Regulation”) from the requirement to publish a prospectus for offers of securities. Accordingly any person making or intending to make an offer in that Member State of securities which are the subject of the offering contemplated in this prospectus supplement may only do so to legal entities which are qualified investors as defined in the Prospectus Regulation, provided that no such offer of securities shall require us or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation, in each case in relation to such offer.

Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities to any legal entity which is not a qualified investor as defined in the Prospectus Regulation. Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters, which constitute the final placement of the securities contemplated in this prospectus supplement.

The securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, or superseded, the “IDD”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently,

S-iii

no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

MiFID II product governance / Professional investors and eligible counterparties only target market

Solely for the purposes of the product governance requirements contained within: (a) MiFID II; (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the “MiFID II Product Governance Requirements”), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any “manufacturer” (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Mandatory Convertible Preferred Stock have been subject to a product approval process, which has determined that such Mandatory Convertible Preferred Stock are: (i) compatible with an end target market of investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the “Target Market Assessment”). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Mandatory Convertible Preferred Stock may decline and investors could lose all or part of their investment; the Mandatory Convertible Preferred Stock offer no guaranteed income and no capital protection; and an investment in the Mandatory Convertible Preferred Stock is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the offer. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Mandatory Convertible Preferred Stock.

Each distributor is responsible for undertaking its own target market assessment in respect of the Mandatory Convertible Preferred Stock and determining appropriate distribution channels.

NOTICE TO INVESTORS IN THE UNITED KINGDOM

This prospectus supplement has been prepared on the basis that any offer of securities in the United Kingdom (“UK”) will be made pursuant to an exemption under Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”) (the “UK Prospectus Regulation”) and the Financial Services and Markets Act 2000 (as amended, the “FSMA”) from the requirement to publish a prospectus for offers of securities. Accordingly any person making or intending to make an offer in the UK of securities which are the subject of the offering contemplated in this prospectus supplement may only do so to legal entities which are qualified investors as defined in the UK Prospectus Regulation, provided that no such offer of securities shall require us or any of the underwriters to publish a prospectus pursuant to Article 3 of the UK Prospectus Regulation or section 85 of the FSMA or supplement a prospectus pursuant to Article 23 of the UK Prospectus Regulation, in each case in relation to such offer.

Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities to any legal entity which is not a qualified investor as defined in the UK Prospectus Regulation. Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters, which constitute the final placement of the securities contemplated in this prospectus supplement.

The securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the UK. For these purposes, a “retail investor” means a

S-iv

person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the EUWA; (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

RISK FACTORS

Investing in our Mandatory Convertible Preferred Stock involves risks. You should consider carefully the risks described below and the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision, including the risks and uncertainties set forth under the heading “Risk Factors” in our 2020 Form 10-K, as well as any other document we may file with the SEC that is incorporated by reference herein. The risks and uncertainties described in this prospectus supplement as well as the documents incorporated by reference herein are not the only ones we are facing. Additional risks and uncertainties that we do not currently know about or that we currently believe are not material may also adversely affect our business. If any of the risks and uncertainties described in this prospectus supplement or the documents incorporated by reference herein or other unknown or currently immaterial risks or uncertainties actually occur, our business, financial condition, results of operations and prospects could be adversely affected in a material way. The occurrence of any of these risks may cause you to lose all or part of your investment in our Mandatory Convertible Preferred Stock.

This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus supplement. See “Cautionary Note Concerning Forward-Looking Statements” in this prospectus supplement. Capitalized but undefined terms used in this “Risk Factors” section have the meanings assigned to them in “Description of Mandatory Convertible Preferred Stock.”

Risks Related to the Mandatory Convertible Preferred Stock

You will bear the risk of a decline in the market price of our Class B common stock between the pricing date for the Mandatory Convertible Preferred Stock and the Mandatory Conversion Date.

The number of shares of our Class B common stock that you will receive upon mandatory conversion of the Mandatory Convertible Preferred Stock is not fixed, but instead will depend on the Applicable Market Value of our Class B common stock, which is the Average VWAP per share of our Class B common stock over the Settlement Period, which is the 20 consecutive Trading Day period beginning on, and including, the 21st Scheduled Trading Day immediately preceding April 1, 2024. The aggregate market value of the shares of our Class B common stock that you would receive upon mandatory conversion may be less than the aggregate Liquidation Preference of the Mandatory Convertible Preferred Stock. Specifically, if the Applicable Market Value of our Class B common stock is less than the Initial Price, which is calculated by dividing $100.00 by the Maximum Conversion Rate of 1.1765 shares of Class B common stock and initially equals approximately $85.00, the market value of our Class B common stock that you would receive upon mandatory conversion of each share of Mandatory Convertible Preferred Stock will be less than the $100.00 liquidation preference per share of Mandatory Convertible Preferred Stock, and an investment in the Mandatory Convertible Preferred Stock would result in a loss, without taking into consideration the payment of dividends. Accordingly, you will bear the entire risk of a decline in the market price of our Class B common stock. Any such decline could be substantial.

In addition, because the number of shares delivered to you upon mandatory conversion will be based upon the Applicable Market Value, the shares of Class B common stock you receive upon mandatory conversion may be worth less than the shares of Class B common stock you would have received had the Applicable Market Value been equal to the VWAP per share of our Class B common stock on the Mandatory Conversion Date or the average VWAP of our Class B common stock over a different period of days.

S-13

Purchasers of the Mandatory Convertible Preferred Stock may not realize any or all of the benefit of an increase in the market price of shares of our Class B common stock. The opportunity for equity appreciation provided by your investment in the Mandatory Convertible Preferred Stock is less than that provided by a direct investment in our Class B common stock.

The market value of each share of our Class B common stock that you will receive upon mandatory conversion of each share of the Mandatory Convertible Preferred Stock on the Mandatory Conversion Date (assuming that all dividends on shares of Mandatory Convertible Preferred Stock will be declared and paid in cash) will only exceed the Liquidation Preference of $100.00 per share of the Mandatory Convertible Preferred Stock if the Applicable Market Value of our Class B common stock exceeds the Threshold Appreciation Price, which is calculated by dividing $100.00 by the Minimum Conversion Rate (and initially is approximately equal to the per share public offering price of our Class B common stock in the Concurrent Offering of our Class B common stock). The Threshold Appreciation Price represents a premium of approximately 17.5% over the Initial Price. If the Applicable Market Value of our Class B common stock is greater than the Threshold Appreciation Price, you will receive on the Mandatory Conversion Date approximately 85% (which percentage is approximately equal to the Initial Price divided by the Threshold Appreciation Price) of the value of our Class B common stock that you would have received if you had made a direct investment in shares of our Class B common stock on the date of this prospectus supplement. This means that the opportunity for equity appreciation provided by an investment in the Mandatory Convertible Preferred Stock is less than that provided by a direct investment in shares of our Class B common stock.

In addition, if the market value of our Class B common stock appreciates and the Applicable Market Value of our Class B common stock is equal to or greater than the Initial Price but less than or equal to the Threshold Appreciation Price, the aggregate market value of our Class B common stock that you would receive upon mandatory conversion (assuming that all dividends on the shares of Mandatory Convertible Preferred Stock will be declared and paid in cash) will only be equal to the aggregate Liquidation Preference of the Mandatory Convertible Preferred Stock, and you will realize no equity appreciation on our Class B common stock.

The adjustment to the conversion rate and the payment of the Fundamental Change Dividend Make-whole Amount upon the occurrence of certain Fundamental Changes may not adequately compensate you for the lost option value and lost dividends as a result of early conversion upon a Fundamental Change.

If a Fundamental Change (as defined in “Description of Mandatory Convertible Preferred Stock— Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”) occurs on or prior to April 1, 2024, the Fundamental Change Conversion Rate will apply to any shares of Mandatory Convertible Preferred Stock converted during the Fundamental Change Conversion Period (as defined in “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”). The Fundamental Change Conversion Rate will be determined as described in “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” In addition, with respect to those shares of Mandatory Convertible Preferred Stock converted, you will also receive, among other consideration, a Fundamental Change Dividend Make-whole Amount in cash (subject to our right to deliver shares of our Class B common stock in lieu of all or part of such amount in cash), subject to the limitations described in “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” If these limitations to the delivery in shares in payment of the Fundamental Change Dividend Amount are reached, we will pay the shortfall in cash to the extent we are permitted to do so under applicable Delaware law. Any such payment in cash may not be permitted by the terms of any of our and our subsidiaries’ then-existing indebtedness. To the extent we are not permitted to pay in cash or deliver shares in respect of the Fundamental Change Dividend Make-whole Amount, in whole in part, due to limitations of applicable Delaware law, we will make an adjustment to the conversion rate subject to certain limitations; provided that, we will not have an obligation to pay shortfall in cash if these limitations to the adjustment of the conversion rate are reached, nor

S-14

shall we have any obligation to deliver shares of our Class B common stock in respect of such shortfall if these limitations to the adjustment of the conversion rate are reached.

Although this adjustment to the conversion rate and the payment of the Fundamental Change Dividend Make-whole Amount are generally designed to compensate you for the lost option value of the Mandatory Convertible Preferred Stock and lost dividends that you will suffer as a result of converting your Mandatory Convertible Preferred Stock upon a Fundamental Change, the Fundamental Change Conversion Rate and Fundamental Change Dividend Make-whole Amount are only an approximation of such lost option value and lost dividends and may not adequately compensate you for your actual loss. In addition, if the price of our Class B common stock is less than $50.00 per share or more than $350.00 per share, the feature of the Fundamental Change Conversion Rate will not compensate you for any loss suffered in connection with a Fundamental Change.

In addition, the agreements governing any of our and our subsidiaries’ future indebtedness may limit our ability to pay cash or deliver shares of our Class B common stock, as the case may be, to converting holders upon a Fundamental Change unless we can repay or refinance the amounts outstanding under such agreements.

Furthermore, our obligation to adjust the conversion rate in connection with a Fundamental Change and pay the Fundamental Change Dividend Make-whole Amount (whether paid or delivered, as the case may be, in cash or shares of our Class B common stock) could be considered a penalty under state law, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies and therefore may not be enforceable in whole or in part.

The Fixed Conversion Rates of the Mandatory Convertible Preferred Stock may not be adjusted for all dilutive events that may adversely affect the market price of the Mandatory Convertible Preferred Stock or the Class B common stock issuable upon conversion of the Mandatory Convertible Preferred Stock.

The Fixed Conversion Rates of the Mandatory Convertible Preferred Stock are subject to adjustment only for the issuance of certain stock dividends on our common stock, subdivisions or combinations of our common stock, the issuance of certain rights, options or warrants to holders of our common stock, distributions of capital stock, indebtedness, or assets to holders of our common stock, distributions of cash dividends to holders of our common stock, and certain issuer tender or exchange offers as described under “Description of Mandatory Convertible Preferred Stock—Anti-dilution Adjustments.” However, other events, such as employee and director grants that are settled in common stock, option exercises, offerings of our common stock or securities convertible into common stock for cash or in connection with acquisitions, or third-party tender or exchange offers, which may adversely affect the market price of our common stock, may not result in any adjustment, even though these other events may adversely affect the market price of our common stock and, therefore, the market price of the Mandatory Convertible Preferred Stock. In addition, the terms of the Mandatory Convertible Preferred Stock do not restrict our ability to offer common stock (including our Class B common stock) or securities convertible into Class B common stock in the future or to engage in other transactions that could dilute our common stock (including our Class B common stock). We have no obligation to consider the specific interests of the holders of the Mandatory Convertible Preferred Stock in engaging in any such offering or transaction.

Purchasers of the Mandatory Convertible Preferred Stock may be adversely affected upon the issuance of a new series of preferred stock ranking on a parity with the Mandatory Convertible Preferred Stock sold in this offering.

Our Amended and Restated Certificate of Incorporation authorizes our board of directors, without the approval of our stockholders, to issue 25,000,000 shares of our preferred stock (including the shares of Mandatory Convertible Preferred Stock), subject to limitations prescribed by applicable law, rules and regulations and the provisions of our Amended and Restated Certificate of Incorporation, as shares of preferred

S-15

stock in series, to establish from time to time the number of shares to be included in each such series and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations or restrictions thereof. The powers, preferences and rights of these additional series of preferred stock may be senior to or on parity with the Mandatory Convertible Preferred Stock, which may reduce its value.

The terms of the Mandatory Convertible Preferred Stock will not restrict our ability to offer a new series of preferred stock that ranks equally with the mandatory convertible preferred stock as to dividend payments and liquidation preference in the future. We have no obligation to consider the specific interests of the holders of the Mandatory Convertible Preferred Stock in engaging in any such offering or transaction.

Regulatory actions may adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Stock.

Investors in, and potential purchasers of, the Mandatory Convertible Preferred Stock who employ, or seek to employ, a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Stock may be adversely impacted by regulatory developments that may limit or restrict such a strategy. The SEC and other regulatory and self-regulatory authorities have implemented various rules and may adopt additional rules in the future that restrict and otherwise regulate short selling and over-the-counter swaps and security-based swaps, which restrictions and regulations may adversely affect the ability of investors in, or potential purchasers of, the Mandatory Convertible Preferred Stock to conduct a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Stock. This could, in turn, adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Stock.

You will have no rights with respect to our Class B common stock until the Mandatory Convertible Preferred Stock is converted, but you may be adversely affected by certain changes made with respect to our Class B common stock.

You will have no rights with respect to our Class B common stock, including rights to respond to Class B common stock tender offers, if any, and rights to receive dividends or other distributions on shares of our Class B common stock, if any (other than through a conversion rate adjustment), prior to the conversion date with respect to a conversion of the Mandatory Convertible Preferred Stock, but your investment in the Mandatory Convertible Preferred Stock may be negatively affected by these events. Upon conversion, you will be entitled to exercise the rights of a holder of shares of our Class B common stock only as to matters for which the record date occurs on or after the conversion date.

You will have no voting rights with respect to the Mandatory Convertible Preferred Stock except under limited circumstances.

You will have no voting rights with respect to the Mandatory Convertible Preferred Stock, except with respect to certain amendments to the terms of the Mandatory Convertible Preferred Stock, in the case of certain dividend arrearages, in certain other limited circumstances and except as specifically required by applicable Delaware law or by our Amended and Restated Certificate of Incorporation. You will have no right to vote for any members of our board of directors except in the case of certain dividend arrearages.

If dividends on any Mandatory Convertible Preferred Stock have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date of the Mandatory Convertible Preferred Stock and ending on, but excluding, July 1, 2021), whether or not for consecutive dividend periods, the holders of such Mandatory Convertible Preferred Stock, voting together as a single class with holders of all other series of preferred stock ranking equally with the Mandatory Convertible Preferred Stock and having similar voting rights, will be entitled at our next special or annual meeting of stockholders to vote for the election of a total of two additional members of our board of directors, subject to certain limitations described in “Description of Mandatory Convertible Preferred Stock—Voting Rights.”

S-16

The Mandatory Convertible Preferred Stock will rank junior to all of our and our subsidiaries’ consolidated liabilities.

In the event of a bankruptcy, liquidation, dissolution or winding up, our assets will be available to pay obligations on the Mandatory Convertible Preferred Stock only after all of our consolidated liabilities have been paid. In addition, the Mandatory Convertible Preferred Stock will rank structurally junior to all existing and future liabilities of our subsidiaries. Your rights to participate in the assets of our subsidiaries upon any bankruptcy, liquidation, dissolution or winding up of any subsidiary will rank junior to the prior claims of that subsidiary’s creditors. In the event of a bankruptcy, liquidation, dissolution or winding up, there may not be sufficient assets remaining, after paying our and our subsidiaries’ liabilities, to pay amounts due on any or all of the Mandatory Convertible Preferred Stock then outstanding.

As of December 31, 2020, our total consolidated indebtedness was approximately $19.73 billion, of which an aggregate of approximately $95 million was secured indebtedness of ours, to which the Mandatory Convertible Preferred Stock would have been subordinated. In addition, we have the ability to, and may incur, additional indebtedness in the future.

Our Amended and Restated Certificate of Incorporation authorizes our board of directors to issue one or more additional series of preferred stock and set the terms of the preferred stock without seeking any further approval from our stockholders. Any preferred stock that is issued will rank ahead of our Class B common stock in terms of dividends and liquidation rights. If we issue additional shares of preferred stock, it may adversely affect the market price of our Class B common stock. Our board of directors also has the power, without stockholder approval, subject to applicable Delaware law and certain limitations set forth in our Amended and Restated Certificate of Incorporation, to set the terms of any such series of preferred stock that may be issued, including voting rights, dividend rights and preferences over our common stock with respect to dividends or upon our dissolution, winding-up and liquidation and other terms. If we issue additional shares of preferred stock in the future that has a preference over our Class B common stock with respect to the payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue additional shares of preferred stock with voting rights, the rights of holders of shares of the Mandatory Convertible Preferred Stock and our Class B common stock or the market price of the Mandatory Convertible Preferred Stock and our Class B common stock could be adversely affected. See “Description of Capital Stock—Preferred Stock” in the accompanying prospectus.

Our ability to declare and pay dividends on our capital stock, including the Mandatory Convertible Preferred Stock, may be limited.

Our declaration and payment of dividends on our capital stock, including the shares of Mandatory Convertible Preferred Stock in the future will be determined by our board of directors (or an authorized committee thereof) in its sole discretion and will depend on our financial condition, earnings, growth prospects, other uses of cash, funding requirements, applicable Delaware law and other factors our board of directors deems relevant.

In addition, credit facilities, indentures or other financing agreements that we enter into in the future may contain provisions that restrict or prohibit our ability to pay cash dividends on our capital stock, including the Mandatory Convertible Preferred Stock. Even if we are permitted under our contractual obligations and Delaware law to pay cash dividends on the Mandatory Convertible Preferred Stock, we may not have sufficient cash to pay cash dividends on the Mandatory Convertible Preferred Stock.

If upon mandatory conversion we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Stock, the applicable conversion rate will be adjusted so that holders receive an additional number of shares of Class B common stock having a market value generally equal to the amount of such accumulated and unpaid dividends, subject to the limitations described under “Description of the Mandatory Convertible Preferred Stock—Mandatory Conversion”. As a result of such

S-17

limitations, the market value of such additional number of shares of Class B common stock may be less than the amount of such accumulated and unpaid dividends. To the extent that the amount of such accumulated and unpaid dividends exceeds the product of such number of additional shares and 97% of the Average Price (as defined herein), we will, to the extent we are able to do so under applicable Delaware law, declare and pay such excess amount in cash pro rata to the holders of the Mandatory Convertible Preferred Stock. However, to the extent we are not permitted to do so under applicable Delaware law, you will not receive such dividends or any other consideration in respect thereof.

If upon an early conversion at the option of a holder (other than during a Fundamental Change), we have not declared and paid all or any portion of the accumulated dividends payable on the Mandatory Convertible Preferred Stock for all full dividend periods ending on or before the dividend payment date prior to the related Early Conversion Date, the applicable conversion rate will be adjusted so that converting holders receive an additional number of shares of our Class B common stock having a market value generally equal to the amount of such accumulated and unpaid dividends, subject to the limitations described under “Description of Mandatory Convertible Preferred Stock—Early Conversion at the Option of the Holder”. As a result of such limitations, the market value of such additional number of shares of Class B common stock may be less than the amount of such accumulated and unpaid dividends. To the extent that the amount of such accumulated and unpaid dividends exceeds the product of such number of additional shares and the Early Conversion Average Price, we will not have any obligation to pay the shortfall in cash or to deliver shares of our Class B common stock in respect of such shortfall.

If upon an early conversion during the Fundamental Change Conversion Period we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Stock for specified periods, we will pay the amount of such accumulated and unpaid dividends in cash, shares of our Class B common stock (or units of exchange property) or any combination thereof, in our sole discretion, subject to the limitations described under “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.” If these limitations to the delivery in shares in payment of accumulated and unpaid dividends are reached, we will pay the shortfall in cash if we are permitted to do so under applicable Delaware law. However, to the extent we are not permitted to do so under applicable Delaware law, you will not receive such dividends or any other consideration in respect thereof.

You may be subject to tax upon an adjustment to the conversion rate of the Mandatory Convertible Preferred Stock or upon a distribution paid in shares of Class B common stock even though you do not receive a corresponding cash distribution.

The conversion rate of the Mandatory Convertible Preferred Stock is subject to adjustment in certain circumstances. Refer to “Description of Mandatory Convertible Preferred Stock—Anti-dilution Adjustments.” If and to the extent that certain adjustments to the conversion rate increase the proportionate interest of a holder of the Mandatory Convertible Preferred Stock in our assets or earnings and profits, such holder may be treated as having received a deemed distribution includable in income as a dividend without the corresponding receipt of any cash or property. In addition, we may make distributions to holders of the Mandatory Convertible Preferred Stock that are paid in shares of our Class B common stock and, although there is some uncertainty, we believe that any such distribution will be taxable for U.S. federal income tax purposes in the same manner as a cash distribution of the same amount. In these circumstances and possibly others, a holder of Mandatory Convertible Preferred Stock may be subject to tax even though it has received no cash with which to pay that tax, thus giving rise to an out-of-pocket expense.

If you are a Non-U.S. Holder (as defined under “Material U.S. Federal Income Tax Considerations”), any of these deemed dividends or distributions made in Class B common stock generally will be subject to U.S. federal withholding tax (currently at a 30% rate, or such lower rate as may be specified by an applicable treaty), which may be withheld from cash, shares of Class B common stock, or sales proceeds otherwise payable to you by the applicable withholding agent.

S-18

See “Material U.S. Federal Income Tax Considerations” for a further discussion of the U.S. federal tax implications for U.S. Holders and Non-U.S. Holders of the purchase, ownership, disposition and conversion of the Mandatory Convertible Preferred Stock and any Class B common stock received in respect thereof.

Certain rights of the holders of the Mandatory Convertible Preferred Stock could delay or prevent an otherwise beneficial takeover or takeover attempt of us and, therefore, the ability of holders of Mandatory Convertible Preferred Stock to exercise their rights associated with a potential Fundamental Change. In addition, provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws may delay or prevent our acquisition by a third party.

Certain rights of the holders of the Mandatory Convertible Preferred Stock could make it more difficult or more expensive for a third party to acquire us. For example, if a Fundamental Change were to occur on or prior to April 1, 2024, holders of the Mandatory Convertible Preferred Stock may have the right to convert their Mandatory Convertible Preferred Stock, in whole or in part, at an increased conversion rate and will also be entitled to receive a Fundamental Change Dividend Make-whole Amount equal to the present value of all remaining dividend payments on their Mandatory Convertible Preferred Stock. See “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount.” These features of the Mandatory Convertible Preferred Stock could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.

In addition, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws contain provisions that could make us a less attractive target for a hostile takeover and could make more difficult or discourage a merger proposal, a tender offer or a proxy contest. Such provisions include:

In addition, as permitted by Delaware law, an amendment to our Amended and Restated Certificate of Incorporation or other corporate action that is approved by stockholders may provide mandatory special treatment for specified groups of nonconsenting stockholders of the same class. For example, an amendment to our Amended and Restated Certificate of Incorporation or other corporate action may provide that shares of common stock held by designated stockholders of record must be cashed out at a price determined by the corporation, subject to applicable dissenters’ rights.

All of these provisions may limit the price that investors may be willing to pay for shares of our common stock and the Mandatory Convertible Preferred Stock. See “Description of Common Stock” and “Description of Mandatory Convertible Preferred Stock.”

An active trading market for the Mandatory Convertible Preferred Stock does not exist and may not develop.

The Mandatory Convertible Preferred Stock is a new issue of securities with no established trading market. The liquidity of the trading market in the Mandatory Convertible Preferred Stock, and the market price quoted for the Mandatory Convertible Preferred Stock, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. We intend to apply to list the Mandatory Convertible Preferred Stock on The Nasdaq

S-19

Global Select Market under the symbol “VIACP.” Even if the Mandatory Convertible Preferred Stock is approved for listing on The Nasdaq Global Select Market, such listing does not guarantee that a trading market for the Mandatory Convertible Preferred Stock will develop or, if a trading market for the Mandatory Convertible Preferred Stock does develop, the depth or liquidity of that market. If an active trading market does not develop or is not maintained, the market price and liquidity of the Mandatory Convertible Preferred Stock may be adversely affected. In that case you may not be able to sell your Mandatory Convertible Preferred Stock at a particular time or you may not be able to sell your Mandatory Convertible Preferred Stock at a favorable price. In addition, as shares of the Mandatory Convertible Preferred Stock are converted, the liquidity of the Mandatory Convertible Preferred Stock that remains outstanding may decrease.

S-20

USE OF PROCEEDS

We estimate that the net proceeds from this offering, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, will be approximately $983.09 million (or approximately $1.13 billion if the underwriters exercise their option in full to purchase additional shares of Mandatory Convertible Preferred Stock, solely to cover over-allotments, if any). We intend to use the combined net proceeds from this offering and the Concurrent Offering for general corporate purposes, including investments in streaming.

DESCRIPTION OF MANDATORY CONVERTIBLE PREFERRED STOCK

The following description is a summary of certain provisions of our 5.75% Series A Mandatory Convertible Preferred Stock, par value $0.001 per share (the “Mandatory Convertible Preferred Stock”). The following summary supplements and, to the extent that it is inconsistent therewith, replaces the description of our preferred stock in the accompanying prospectus.

A copy of the Certificate of Designations setting forth the terms of the Mandatory Convertible Preferred Stock, which we refer to as the “Certificate of Designations” as well as our Amended and Restated Certificate of Incorporation, which we refer to as our “Certificate of Incorporation,” is available upon request from us at the address set forth in the section of this prospectus supplement entitled “Incorporation by Reference.” This description of the terms of the Mandatory Convertible Preferred Stock is not complete and is subject to, and qualified in its entirety by reference to, the provisions of our Certificate of Incorporation and the Certificate of Designations.

For purposes of this description, references to:

General

Under our Certificate of Incorporation, our board of directors is authorized to provide, without further stockholder action, for the issuance of up to 25,000,000 shares of preferred stock, par value $0.001 per share, and the designation of each series of preferred stock and, with respect to each such series, to fix the number of shares constituting such series and fix the voting power, full or limited or no voting power, the powers, preferences and relative, participating, option or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of each series. As of the date of this prospectus supplement, no shares of preferred stock are outstanding.

At the closing of this offering, we will issue 10,000,000 shares of Mandatory Convertible Preferred Stock. In addition, we have granted the underwriters an option to purchase up to 1,500,000 additional shares of Mandatory Convertible Preferred Stock, solely to cover over-allotments, if any, as described under “Underwriting.”

When issued, the Mandatory Convertible Preferred Stock and our Class B common stock issued upon the conversion of the Mandatory Convertible Preferred Stock will be fully paid and non-assessable. The holders of the Mandatory Convertible Preferred Stock will have no preemptive or preferential rights to purchase or subscribe for any class of our stock, obligations, warrants or other securities.

S-22

Ranking

The Mandatory Convertible Preferred Stock, with respect to dividend rights and/or distribution rights upon our liquidation, winding-up or dissolution, as applicable, will rank:

In addition, with respect to dividend rights and distribution rights upon our liquidation, winding-up or dissolution, the Mandatory Convertible Preferred Stock will be structurally subordinated to existing and future indebtedness and other obligations of each of our subsidiaries. See “Risk Factors—Risks Relating to the Mandatory Convertible Preferred Stock—The Mandatory Convertible Preferred Stock will rank junior to all of our and our subsidiaries’ consolidated liabilities.”

As of December 31, 2020, we had total outstanding indebtedness of approximately $19.73 billion, and no outstanding shares of preferred stock.

Listing

We intend to apply to list the Mandatory Convertible Preferred Stock on The Nasdaq Global Select Market under the symbol “VIACP” and, if approved, we expect trading to commence within 30 days of the Initial Issue Date. In addition, upon listing, we have agreed to use our commercially reasonable efforts to keep the Mandatory Convertible Preferred Stock listed on The Nasdaq Global Select Market. However, there can be no assurance that the Mandatory Convertible Preferred Stock will be listed, and if listed, that it will continue to be listed. Listing the Mandatory Convertible Preferred Stock on The Nasdaq Global Select Market does not guarantee that a trading market will develop or, if a trading market does develop, the depth or liquidity of that market or the ability of holders to sell their Mandatory Convertible Preferred Stock easily.

Dividends

Subject to the rights of holders of any class or series of our capital stock ranking senior to the Mandatory Convertible Preferred Stock as to dividend rights, holders of the Mandatory Convertible Preferred Stock will be entitled to receive, when, as and if declared by our board of directors, or an authorized committee thereof, only out of funds legally available to pay dividends, in the case of dividends paid in cash, and shares of Class B common stock legally available to be issued, in the case of dividends paid in shares of Class B common stock, cumulative dividends at the rate per annum of 5.75% of the Liquidation Preference of $100.00 per share of the Mandatory Convertible Preferred Stock (equivalent to $5.75 per annum per share), payable in cash, by delivery of shares of our Class B common stock or through any combination of cash and shares of our Class B common stock, as determined by us in our sole discretion (subject to the limitations described below).

S-23

If declared, dividends on the Mandatory Convertible Preferred Stock will be payable quarterly on January 1, April 1, July 1 and October 1 of each year to, and including, April 1, 2024 commencing on July 1, 2021 (each, a “Dividend Payment Date”), at such annual rate, and dividends shall accumulate from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the Initial Issue Date of the Mandatory Convertible Preferred Stock, whether or not in any dividend period or periods there have been funds legally available to pay dividends.

If declared, dividends will be payable on the relevant Dividend Payment Date to holders of record of the Mandatory Convertible Preferred Stock as they appear on our stock register at the close of business on the March 15, June 15, September 15 or December 15, as the case may be, immediately preceding the relevant Dividend Payment Date (each, a “Regular Record Date”), whether or not such holders early convert their shares, or such shares are automatically converted, after a Regular Record Date and on or prior to the immediately succeeding Dividend Payment Date. These Regular Record Dates will apply regardless of whether a particular Regular Record Date is a Business Day. If a Dividend Payment Date is not a Business Day, payment will be made on the next succeeding Business Day, without any interest or other payment in lieu of interest accruing with respect to this delay.

A full dividend period is the period from, and including, a Dividend Payment Date to, but excluding, the next Dividend Payment Date, except that the initial dividend period will commence on, and include, the Initial Issue Date of the Mandatory Convertible Preferred Stock and will end on, and exclude, the July 1, 2021 Dividend Payment Date. The amount of dividends payable on each share of the Mandatory Convertible Preferred Stock for each full dividend period (subsequent to the initial dividend period) will be computed by dividing the annual dividend rate by four. Dividends payable on the Mandatory Convertible Preferred Stock for the initial dividend period and any other partial dividend period will be computed based upon the actual number of days elapsed during the period over a 360-day year (consisting of twelve 30-day months). Accordingly, the dividend on the Mandatory Convertible Preferred Stock for the initial dividend period, assuming the Initial Issue Date is March 26, 2021 will be $1.4535 per share of Mandatory Convertible Preferred Stock (based on the annual dividend rate of 5.75% and a Liquidation Preference of $100.00 per share) and will be payable, when, as and if declared, on July 1, 2021 to the holders of record thereof on June 15, 2021. The dividend on the Mandatory Convertible Preferred Stock for each subsequent full dividend period, when, as and if declared, will be $1.4375 per share of Mandatory Convertible Preferred Stock (based on the annual dividend rate of 5.75% and a Liquidation Preference of $100.00 per share). Accumulated dividends on shares of the Mandatory Convertible Preferred Stock will not bear interest, nor shall additional dividends be payable thereon, if they are paid subsequent to the applicable Dividend Payment Date.

No dividend on the Mandatory Convertible Preferred Stock will be paid unless and until our board of directors, or an authorized committee of our board of directors, declares a dividend payable with respect to the Mandatory Convertible Preferred Stock. No dividend will be declared or paid upon, or any sum of cash or number of shares of our Class B common stock set apart for the payment of dividends on, any outstanding shares of Mandatory Convertible Preferred Stock with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid on, or a sufficient sum of cash or number of shares of our Class B common stock has been set apart for the payment of such dividends on, all outstanding shares of Mandatory Convertible Preferred Stock.

Except as described herein, dividends on shares of Mandatory Convertible Preferred Stock converted into Class B common stock will cease to accumulate on April 1, 2024, the Fundamental Change Conversion Date or the Early Conversion Date, as applicable.

Our ability to declare and pay cash dividends and to make other distributions with respect to our capital stock, including our Mandatory Convertible Preferred Stock may be limited by the terms of any of our and our subsidiaries’ then-existing indebtedness. In addition, our ability to declare and pay dividends may also be limited by Delaware law. See “Risk Factors—Risks Relating to the Mandatory Convertible Preferred—Our ability to declare and pay dividends on the Mandatory Convertible Preferred Stock may be limited.”

S-24

Method of Payment of Dividends

Subject to the limitations described below, we may pay any declared dividend (or any portion of any declared dividend) on the shares of Mandatory Convertible Preferred Stock (whether or not for a current dividend period or any prior dividend period) determined in our sole discretion:

We will make each payment of a declared dividend on the shares of Mandatory Convertible Preferred Stock in cash, except to the extent we elect to make all or any portion of such payment in shares of our Class B common stock. We will give the holders of the Mandatory Convertible Preferred Stock notice of any such election, and the portion of such payment that will be made in cash and the portion that will be made in shares of our Class B common stock no later than ten Scheduled Trading Days (as defined under “—Mandatory Conversion—Definitions”) prior to the Dividend Payment Date for such dividend; provided that if we do not provide timely notice of this election, we will be deemed to have elected to pay the relevant dividend in cash.

All cash payments to which a holder of the Mandatory Convertible Preferred Stock is entitled in connection with a declared dividend on the shares of Mandatory Convertible Preferred Stock will be computed to the nearest cent. If we elect to make any such payment of a declared dividend, or any portion thereof, in shares of our Class B common stock, such shares shall be valued for such purpose, in the case of any dividend payment or portion thereof, at 97% of the Average VWAP (as defined under “—Mandatory Conversion—Definitions”) per share of our Class B common stock over the five consecutive Trading Day (as defined under “—Mandatory Conversion— Definitions”) period ending on, and including, the second Trading Day prior to the applicable Dividend Payment Date (the “Average Price”).

No fractional shares of our Class B common stock will be delivered to the holders of the Mandatory Convertible Preferred Stock in payment or partial payment of dividends. We will instead, to the extent we are legally permitted to do so, pay a cash adjustment (computed to the nearest cent) to each holder that would otherwise be entitled to a fraction of a share of our Class B common stock based on the Average Price with respect to such dividend. In the event that we cannot pay cash in lieu of a fractional share, we will instead round up our share delivery obligation to each holder to the nearest whole share of Class B common stock.

To the extent a shelf registration statement is required in our reasonable judgment in connection with the issuance of or for resales of shares of our Class B common stock issued as payment of a dividend on the shares of Mandatory Convertible Preferred Stock, including dividends paid in connection with a conversion, we will, to the extent such a shelf registration statement is not currently filed and effective, use our commercially reasonable efforts to file and maintain the effectiveness of such a shelf registration statement until the earlier of (i) such time as all such shares of Class B common stock have been resold thereunder and (ii) such time as all such shares are freely tradable without registration pursuant to Rule 144 by holders thereof that are not, and have not been within the three months preceding, “affiliates” of ours for purposes of the Securities Act of 1933 (the “Securities Act”). To the extent applicable, we will also use our commercially reasonable efforts to have the shares of our Class B common stock so issued approved for listing on The Nasdaq Global Select Market (or if our Class B common stock is not listed on The Nasdaq Global Select Market, on the principal other U.S. national or regional securities exchange on which our Class B common stock is then listed), and qualified or registered under applicable state securities laws, if required; provided that we will not be required to qualify as a foreign corporation or to take any action that would subject us to general service of process in any such jurisdiction where we are not presently qualified or where we are not presently subject to taxation as a foreign corporation and such qualification or action would subject us to such taxation.

S-25

Notwithstanding the foregoing, in no event will the number of shares of our Class B common stock delivered in connection with any declared dividend, including any declared dividend payable in connection with a conversion, exceed a number equal to:

To the extent that the amount of any declared dividend exceeds the product of (x) the number of shares of our Class B common stock delivered in connection with such declared dividend and (y) 97% of the Average Price, we will, to the extent we are able to do so under applicable Delaware law, notwithstanding any notice by us to the contrary, pay such excess amount in cash (computed to the nearest cent). Any such payment in cash may not be permitted by the terms of any of our and our subsidiaries’ then-existing indebtedness. To the extent that we are not able to pay such excess amount in cash under applicable Delaware law, we will not have any obligation to pay such amount in cash or deliver additional shares of our Class B common stock in respect of such amount, and such amount will not form a part of the cumulative dividends that may be deemed to accumulate on the shares of Mandatory Convertible Preferred Stock.

Dividend Stopper

So long as any share of Mandatory Convertible Preferred Stock remains outstanding, no dividend or distribution shall be declared or paid on our common stock or any other class or series of Junior Stock, and no common stock or any other class or series of Junior Stock or Parity Stock shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by us or any of our subsidiaries unless all accumulated and unpaid dividends for all preceding dividend periods have been declared and paid in full in cash, shares of our Class B common stock or a combination thereof on, or a sufficient sum of cash or number of shares of our Class B common stock has been set apart for the payment of such dividends on, all outstanding shares of Mandatory Convertible Preferred Stock.

The foregoing limitation shall not apply to:

S-26

The phrase “Share Dilution Amount” means the increase in the number of diluted shares of our common stock outstanding (determined in accordance with U.S. GAAP, and as measured from the Initial Issue Date) resulting from the grant, vesting or exercise of equity-based compensation to directors, employees and agents and equitably adjusted for any stock split, stock dividend, reverse stock split, reclassification or similar transaction.

When dividends on shares of the Mandatory Convertible Preferred Stock (i) have not been declared and paid in full on any Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from such Dividend Payment Dates, on a dividend payment date falling within a regular dividend period related to such Dividend Payment Date), or (ii) have been declared but a sum of cash or number of shares of our Class B common stock sufficient for payment thereof has not been set aside for the benefit of the holders thereof on the applicable Regular Record Date, no dividends may be declared or paid on any shares of Parity Stock unless dividends are declared on the shares of Mandatory Convertible Preferred Stock such that the respective amounts of such dividends declared on the shares of Mandatory Convertible Preferred Stock and such shares of Parity Stock shall be allocated pro rata among the holders of the shares of Mandatory Convertible Preferred Stock and the holders of any shares of Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, we shall allocate those payments so that the respective amounts of those payments for the declared dividend bear the same ratio to each other as all accumulated and unpaid dividends per share on the shares of Mandatory Convertible Preferred Stock and such shares of Parity Stock bear to each other (subject to their having been declared by our board of directors, or an authorized committee thereof, out of funds legally available to pay dividends); provided that any unpaid dividends on the Mandatory Convertible Preferred Stock will continue to accumulate. For purposes of this calculation, with respect to non-cumulative Parity Stock, we will use the full amount of dividends that would be payable for the most recent dividend period if dividends were declared in full on such non-cumulative Parity Stock.

Subject to the foregoing, and not otherwise, such dividends as may be determined by our board of directors, or an authorized committee thereof, may be declared and paid (payable in cash or other property or securities) on any securities, including our common stock and other Junior Stock, from time to time out of funds legally available to pay dividends, and holders of the Mandatory Convertible Preferred Stock shall not be entitled to participate in any such dividends.

Redemption

The Mandatory Convertible Preferred Stock will not be redeemable. However, at our option, we may purchase or otherwise acquire (including in an exchange transaction) the Mandatory Convertible Preferred Stock from time to time in the open market, by tender or exchange offer or otherwise, without the consent of, or notice to, holders.

Liquidation Preference

In the event of our voluntary or involuntary liquidation, winding-up or dissolution, each holder of the Mandatory Convertible Preferred Stock will be entitled to receive a Liquidation Preference in the amount of $100.00 per share of the Mandatory Convertible Preferred Stock (the “Liquidation Preference”), plus an amount

S-27

equal to accumulated and unpaid dividends on such shares, whether or not declared, to, but excluding, the date fixed for liquidation, winding-up or dissolution to be paid out of our assets legally available for distribution to our stockholders, after satisfaction of indebtedness and other liabilities to our creditors and holders of shares of any class or series of our capital stock ranking senior to the Mandatory Convertible Preferred Stock as to distribution rights upon our liquidation, winding up or dissolution and before any payment or distribution is made to holders of any class or series of our capital stock ranking junior to the Mandatory Convertible Preferred Stock as to distribution rights upon our liquidation, winding up or dissolution (including our common stock). If, upon our voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to (1) the Liquidation Preference, plus an amount equal to accumulated and unpaid dividends, whether or not declared, to, but excluding, the date fixed for such liquidation, winding-up or dissolution, on the shares of Mandatory Convertible Preferred Stock and (2) the liquidation preference of, and the amount of accumulated and unpaid dividends, whether or not declared, to, but excluding, the date fixed for such liquidation, winding-up or dissolution, on the shares of all Parity Stock are not paid in full, all holders of the Mandatory Convertible Preferred Stock and all holders of any such Parity Stock will share equally and ratably in any distribution of our assets in proportion to their respective liquidation preferences and amounts equal to accumulated and unpaid dividends (if any) to which they are entitled. After payment of the full amount of the Liquidation Preference and an amount equal to accumulated and unpaid dividends to which they are entitled, the holders of the Mandatory Convertible Preferred Stock will have no right or claim to any of our remaining assets.

Neither the sale, lease nor exchange of all or substantially all of our assets or business (other than in connection with our liquidation, winding-up or dissolution), nor our merger or consolidation into or with any other person, will be deemed to be our voluntary or involuntary liquidation, winding-up or dissolution.

Our Certificate of Incorporation, including the Certificate of Designations, will not contain any provision requiring funds to be set aside to protect the Liquidation Preference of the Mandatory Convertible Preferred Stock even though it is substantially in excess of the par value thereof.

Voting Rights

The holders of the Mandatory Convertible Preferred Stock will not have voting rights other than those described below, except as specifically required by Delaware law or by our Certificate of Incorporation from time to time.

Whenever dividends on any shares of the Mandatory Convertible Preferred Stock have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the Initial Issue Date and ending on, but excluding, July 1, 2021), whether or not for consecutive dividend periods (a “Nonpayment”), the authorized number of directors on our board of directors will, at the next annual meeting of stockholders or at a special meeting of stockholders as provided below, automatically be increased by two and the holders of record of such shares of the Mandatory Convertible Preferred Stock, voting together as a single class with holders of record of any and all other series of Voting Preferred Stock (as defined below) then outstanding, will be entitled, at our next annual meeting of stockholders or at a special meeting of stockholders as provided below, to vote for the election of a total of two additional members of our board of directors (the “Preferred Stock Directors”); provided that the election of any such Preferred Stock Directors will not cause us to violate the corporate governance requirements of The Nasdaq Global Select Market (or any other exchange or automated quotation system on which our securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors; provided further that our board of directors shall, at no time, include more than two Preferred Stock Directors.

In the event of a Nonpayment, the holders of record of at least 25% of the shares of the Mandatory Convertible Preferred Stock and any other series of Voting Preferred Stock may request that a special meeting of stockholders be called to elect such Preferred Stock Directors (provided, however, to the extent permitted by our Amended and Restated Bylaws, if our next annual or a special meeting of stockholders is scheduled to be held

S-28

within 90 days of the receipt of such request, the election of such Preferred Stock Directors will be included in the agenda for, and will be held at, such scheduled annual or special meeting of stockholders). The Preferred Stock Directors will stand for reelection annually, at each subsequent annual meeting of the stockholders, so long as the holders of the Mandatory Convertible Preferred Stock continue to have such voting rights.

At any meeting at which the holders of the Mandatory Convertible Preferred Stock are entitled to elect Preferred Stock Directors, the holders of record of a majority of the then outstanding shares of the Mandatory Convertible Preferred Stock and all other series of Voting Preferred Stock, present in person or represented by proxy, will constitute a quorum and the vote of the holders of record of a majority of such shares of the Mandatory Convertible Preferred Stock and other Voting Preferred Stock so present or represented by proxy at any such meeting at which there shall be a quorum shall be sufficient to elect the Preferred Stock Directors.

As used in this prospectus supplement, “Voting Preferred Stock” means any other class or series of our Parity Stock upon which like voting rights for the election of directors have been conferred and are exercisable. Whether a plurality, majority or other portion in voting power of the Mandatory Convertible Preferred Stock and any other Voting Preferred Stock have been voted in favor of any matter shall be determined by reference to the respective liquidation preference amounts of the Mandatory Convertible Preferred Stock and such other Voting Preferred Stock voted.

If and when all accumulated and unpaid dividends on the Mandatory Convertible Preferred Stock have been paid in full (a “Nonpayment Remedy”), the holders of the Mandatory Convertible Preferred Stock shall immediately and, without any further action by us, be divested of the foregoing voting rights, subject to the revesting of such rights in the event of each subsequent Nonpayment. If such voting rights for the holders of the Mandatory Convertible Preferred Stock and all other holders of Voting Preferred Stock have terminated, the term of office of each Preferred Stock Director so elected will terminate at such time and the authorized number of directors on our board of directors shall automatically decrease by two.

Any Preferred Stock Director may be removed at any time, with or without cause, by the holders of record of a majority in voting power of the outstanding shares of the Mandatory Convertible Preferred Stock and any other series of Voting Preferred Stock then outstanding (voting together as a single class) when they have the voting rights described above. In the event that a Nonpayment shall have occurred and there shall not have been a Nonpayment Remedy, any vacancy in the office of a Preferred Stock Director (other than prior to the initial election of Preferred Stock Directors after a Nonpayment) may be filled by the written consent of the Preferred Stock Director remaining in office, except in the event that such vacancy is created as a result of such Preferred Stock Director being removed or if no Preferred Stock Director remains in office, such vacancy may be filled by a vote of the holders of record of a majority in voting power of the outstanding shares of the Mandatory Convertible Preferred Stock and any other series of Voting Preferred Stock then outstanding (voting together as a single class) when they have the voting rights described above; provided that the election of any such Preferred Stock Directors will not cause us to violate the corporate governance requirements of The Nasdaq Global Select Market (or any other exchange or automated quotation system on which our securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors. The Preferred Stock Directors will each be entitled to one vote per director on any matter that comes before our board of directors for a vote.

So long as any shares of Mandatory Convertible Preferred Stock remain outstanding, we will not, without the affirmative vote or consent of the holders of at least two-thirds in voting power of the outstanding shares of Mandatory Convertible Preferred Stock and all other series of Voting Preferred Stock at the time outstanding and entitled to vote thereon, voting together as a single class, given in person or by proxy, either in writing or at an annual or special meeting of such stockholders:

S-29

provided, however, that in the event that a transaction would trigger voting rights under both the second and third bullet point above, the third bullet point will govern; provided, further, however, that:

will be deemed not to adversely affect the rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Stock and shall not require the affirmative vote or consent of holders of the Mandatory Convertible Preferred Stock.

Our Certificate of Incorporation and Delaware law permit us, without the approval of any of our stockholders (including any holders of the Mandatory Convertible Preferred Stock), to establish and issue a new series of preferred stock ranking equally with or junior to the Mandatory Convertible Preferred Stock, which may dilute the voting and other interests of holders of Mandatory Convertible Preferred Stock.

If any amendment, alteration, repeal, binding share exchange, reclassification, merger or consolidation described above would adversely affect the special rights, preferences, privileges or voting powers of one or more but not all series of Voting Preferred Stock (including the Mandatory Convertible Preferred Stock for this purpose), then only the series of Voting Preferred Stock the special rights, preferences, privileges or voting powers of which are adversely affected and entitled to vote, shall vote as a class in lieu of all series of Voting Preferred Stock.

Without the consent of the holders of the Mandatory Convertible Preferred Stock, so long as such action does not adversely affect the special rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Stock and limitations and restrictions thereof, we may amend, alter, supplement or repeal any terms of the Mandatory Convertible Preferred Stock:

S-30

Without the consent of the holders of the Mandatory Convertible Preferred Stock, we may amend, alter, supplement or repeal any terms of the Mandatory Convertible Preferred Stock to (i) conform the terms of the Mandatory Convertible Preferred Stock to the description thereof in the accompanying prospectus as supplemented and/or amended by this “Description of Mandatory Convertible Preferred Stock” section of the preliminary prospectus supplement for the Mandatory Convertible Preferred Stock, as supplemented by the related pricing term sheet or (ii) amend the Certificate of Designations for the Mandatory Convertible Preferred Stock in connection with a Reorganization Event to the extent required pursuant to the provisions below under the heading “—Recapitalization, Reclassifications and Changes of Our Class B Common Stock.”

Mandatory Conversion

Each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert on the Mandatory Conversion Date (as defined below), into a number of shares of our Class B common stock equal to the conversion rate described below.

The conversion rate, which is the number of shares of our Class B common stock issuable upon conversion of each share of the Mandatory Convertible Preferred Stock on the Mandatory Conversion Date (excluding any shares of our Class B common stock issued in respect of accrued and unpaid dividends, as described below), will be as follows:

We refer to the Minimum Conversion Rate and the Maximum Conversion Rate collectively as the “Fixed Conversion Rates.” The “Threshold Appreciation Price” is calculated by dividing $100.00 by the Minimum Conversion Rate, and represents an approximately 17.5% appreciation over the Initial Price. The “Initial Price” is calculated by dividing $100.00 by the Maximum Conversion Rate of 1.1765 shares of Class B common stock, and initially is approximately equal to the per share public offering price of our Class B common stock in the Concurrent Offering. The Fixed Conversion Rates are subject to adjustment as described in “—Anti-dilution Adjustments” below.

If we declare a dividend on the Mandatory Convertible Preferred Stock for the dividend period ending on, but excluding, April 1, 2024, we will pay such dividend to the holders of record as of the immediately preceding Regular Record Date, as described above under “—Dividends.” If on or prior to April 1, 2024 we have not declared all or any portion of the accumulated and unpaid dividends on the Mandatory Convertible Preferred

S-31

Stock, the conversion rate will be adjusted so that holders receive an additional number of shares of our Class B common stock equal to:

To the extent that the Mandatory Conversion Additional Conversion Amount exceeds the product of the number of additional shares and 97% of the Average Price, we will, to the extent we are able to do so under applicable Delaware law, declare and pay such excess amount in cash (computed to the nearest cent) pro rata per share to the holders of the Mandatory Convertible Preferred Stock. Any such payment in cash may not be permitted by the terms of any of our and our subsidiaries’ then-existing indebtedness. To the extent that we are not able to pay such excess amount in cash under applicable Delaware law, we will not have any obligation to pay such amount in cash or deliver additional shares of our Class B common stock in respect of such amount, and such amount will not form a part of the cumulative dividends that may be deemed to accumulate on the shares of Mandatory Convertible Preferred Stock.

Hypothetical Conversion Values Upon Mandatory Conversion

For illustrative purposes only, the following table shows the number of shares of our Class B common stock that a holder of the Mandatory Convertible Preferred Stock would receive upon mandatory conversion of one share of Mandatory Convertible Preferred Stock at various Applicable Market Values for our Class B common stock. The table assumes that there will be no conversion adjustments as described below in “—Anti-dilution Adjustments” and that dividends on the Mandatory Convertible Preferred Stock will be declared and paid in cash (and not in additional shares of our Class B common stock). The actual Applicable Market Value of our Class B common stock may differ from those set forth in the table below. Given an Initial Price of approximately $85.00 and a Threshold Appreciation Price of approximately $99.87, a holder of Mandatory Convertible Preferred Stock would receive on the Mandatory Conversion Date the number of shares of our Class B common stock per share of Mandatory Convertible Preferred Stock set forth below, subject to the provisions described below with respect to any fractional share of our Class B common stock:

Accordingly, assuming that the market price of our Class B common stock on the Mandatory Conversion Date is the same as the Applicable Market Value of our Class B common stock, the aggregate market value of our Class B common stock you receive upon mandatory conversion of a share of Mandatory Convertible

S-32

Preferred Stock (excluding any shares of our Class B common stock you receive in respect of accrued and unpaid dividends) will be:

Definitions

“Applicable Market Value” means the Average VWAP per share of our Class B common stock over the Settlement Period.

“Settlement Period” means the 20 consecutive Trading Day period commencing on, and including, the 21st Scheduled Trading Day immediately preceding April 1, 2024.

“Mandatory Conversion Date” means the second Business Day immediately following the last Trading Day of the Settlement Period. The Mandatory Conversion Date is expected to be April 1, 2024. If the Mandatory Conversion Date occurs after April 1, 2024 (whether because a Scheduled Trading Day during the Settlement Period is not a Trading Day due to the occurrence of a Market Disruption Event or otherwise), no interest or other amounts will accrue as a result of such postponement.

A “Trading Day” means a day on which:

provided, that if our common stock is not listed or admitted for trading, “Trading Day” means a “Business Day.”

A “Scheduled Trading Day” is any day that is scheduled to be a Trading Day.

“Market Disruption Event” means:

“Relevant Stock Exchange” means The Nasdaq Global Select Market or, if our Class B common stock is not then listed on The Nasdaq Global Select Market, on the principal other U.S. national or regional securities exchange on which our Class B common stock is then listed or, if our Class B common stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which our Class B common stock is then listed or admitted for trading.

“VWAP” per share of our Class B common stock on any Trading Day means the per share volume-weighted average price as displayed on Bloomberg page “VIAC <EQUITY> AQR” (or its equivalent successor if such

S-33

page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such Trading Day, taking into account any adjustments made to reported trades at or prior to 4:10 p.m., New York time, but excluding any after-market trades (or if such volume-weighted average price is not available or is manifestly erroneous, the market value per share of our Class B common stock on such Trading Day as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose, which may include any of the underwriters for this offering). The “Average VWAP” per share over a certain period means the arithmetic average of the VWAP per share for each Trading Day in such period.

Early Conversion at the Option of the Holder

Other than during a Fundamental Change Conversion Period (as defined below in “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount”), holders of shares of Mandatory Convertible Preferred Stock will have the right to convert their Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at any time prior to April 1, 2024 (any such conversion, an “Early Conversion”), into shares of our Class B common stock at the Minimum Conversion Rate of shares of our Class B common stock per share of Mandatory Convertible Preferred Stock, subject to adjustments as described in “—Anti-dilution Adjustments” below.

If, as of the conversion date (as defined below under “—Conversion Procedures—Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change”) of any Early Conversion (the “Early Conversion Date”), we have not declared all or any portion of the accumulated and unpaid dividends for all full dividend periods ending on or before the Dividend Payment Date immediately prior to such Early Conversion Date, the conversion rate for such Early Conversion will be adjusted so that holders converting their Mandatory Convertible Preferred Stock at such time receive an additional number of shares of our Class B common stock equal to:

To the extent that the Early Conversion Additional Conversion Amount exceeds the product of such number of additional shares of Class B common stock and the Early Conversion Average Price, we will not have any obligation to pay the shortfall in cash or deliver shares of our Class B common stock in respect of such shortfall.

Except as described above, upon any Early Conversion of any Mandatory Convertible Preferred Stock, we will make no payment or allowance for unpaid dividends on such shares of the Mandatory Convertible Preferred Stock, unless such Early Conversion Date occurs after the Regular Record Date for a declared dividend and on or prior to the immediately succeeding Dividend Payment Date, in which case such dividend will be paid on such Dividend Payment Date to the holder of record of the converted shares of the Mandatory Convertible Preferred Stock as of such Regular Record Date, as described under “—Dividends.”

S-34

Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount

General

If a “Fundamental Change” (as defined below) occurs on or prior to April 1, 2024, holders of the Mandatory Convertible Preferred Stock will have the right (the “Fundamental Change Conversion Right”) during the Fundamental Change Conversion Period (as defined below) to:

subject in the case of clauses (ii) and (iii) to certain limitations with respect to the number of shares of our Class B common stock that we will be required to deliver, all as described below. Notwithstanding clauses (ii) and (iii) above, if the Fundamental Change Effective Date (as defined below) or the Fundamental Change Conversion Date (as defined below) falls after the Regular Record Date for a declared dividend and prior to the next Dividend Payment Date, such dividend will be paid on such Dividend Payment Date to the holders of record as of such Regular Record Date, as described under “—Dividends” and will not be included in the Accumulated Dividend Amount, and the Fundamental Change Dividend Make-whole Amount will not include the present value of the payment of such dividend.

To exercise this Fundamental Change Conversion Right, holders must submit their shares of the Mandatory Convertible Preferred Stock for conversion at any time during the period, which we call the “Fundamental Change Conversion Period,” beginning on, and including, the Fundamental Change Effective Date and ending at the close of business on the date that is 20 calendar days after the Fundamental Change Effective Date (or, if later, the date that is 20 calendar days after the date of notice of such Fundamental Change), but in no event later than April 1, 2024. Holders of the Mandatory Convertible Preferred Stock that submit the shares for conversion during the Fundamental Change Conversion Period shall be deemed to have exercised their Fundamental Change Conversion Right. Holders of the Mandatory Convertible Preferred Stock who do not submit their shares for conversion during the Fundamental Change Conversion Period will not be entitled to convert their Mandatory Convertible Preferred Stock at the relevant Fundamental Change Conversion Rate or to receive the relevant Fundamental Change Dividend Make-whole Amount or the relevant Accumulated Dividend Amount. The “Fundamental Change Conversion Date” refers to the conversion date (as defined below under “—Conversion Procedures—Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change”) during the Fundamental Change Conversion Period.

We will notify holders of the Fundamental Change Effective Date as soon as reasonably practicable and in any event no later than the second Business Day immediately following the Fundamental Change Effective Date.

A “Fundamental Change” will be deemed to have occurred, at any time after the Initial Issue Date of the Mandatory Convertible Preferred Stock, if any of the following occurs:

S-35

However, a transaction or transactions described in clause (i) or clause (ii) above will not constitute a Fundamental Change if at least 90% of the consideration received or to be received by holders of our Class B common stock, excluding cash payments for fractional shares or pursuant to statutory appraisal rights, in connection with such transaction or transactions consists of shares of common stock that are listed or quoted on any of The Nasdaq Global Select Market, The Nasdaq Global Market or The New York Stock Exchange, (or another U.S. national securities exchange or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions such consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) becomes the Exchange Property.

“Redstone Family Members” includes only the following persons: (i) the estate of Mr. Sumner Redstone; (ii) each descendant of Mr. Redstone or former spouse of Mr. Redstone and their respective estates, guardians, conservators or committees; (iii) any former spouse of Mr. Redstone; (iv) each “Family Controlled Entity” (as defined below); and (v) the trustees, in their respective capacities as such, of each “Family Controlled Trust” (as defined below). The term “Family Controlled Entity” means (i) any not-for-profit corporation if more than 50% of its board of directors is composed of Redstone Family Members; (ii) any other corporation if more than 50% of the value of its outstanding equity is owned by Redstone Family Members; (iii) any partnership if more than 50% of the value of its partnership interests is owned by Redstone Family Members; and (iv) any limited liability or similar company if more than 50% of the value of the company is owned by Redstone Family Members. The term “Family Controlled Trust” includes certain trusts existing on March 23, 2021 and any other trusts the primary beneficiaries of which are Redstone Family Members, spouses of Redstone Family Members and/or charitable organizations, provided that if the trust is a wholly charitable trust, more than 50% of the trustees of such trust consist of Redstone Family Members.

Fundamental Change Conversion Rate

The Fundamental Change Conversion Rate will be determined by reference to the table below and is based on the effective date of the Fundamental Change (the “Fundamental Change Effective Date”) and the price (the “Fundamental Change Share Price”) paid (or deemed paid) per share of our Class B common stock in such Fundamental Change. If all holders of our Class B common stock receive only cash in exchange for their Class B common stock in the Fundamental Change, the Fundamental Change Share Price shall be the cash amount paid per share of Class B common stock. Otherwise, the Fundamental Change Share Price shall be the Average VWAP per share of our Class B common stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the relevant Fundamental Change Effective Date.

The Fundamental Change Share Prices set forth in the first row of the table (i.e., the column headers) will be adjusted as of any date on which the Fixed Conversion Rates of the Mandatory Convertible Preferred Stock are

S-36

adjusted. The adjusted Fundamental Change Share Prices will equal (i) the Fundamental Change Share Prices applicable immediately prior to such adjustment, multiplied by (ii) a fraction, the numerator of which is the Minimum Conversion Rate immediately prior to the adjustment giving rise to the Fundamental Change Share Price adjustment and the denominator of which is the Minimum Conversion Rate as so adjusted. Each of the Fundamental Change Conversion Rates in the table below will be subject to adjustment in the same manner and at the same time as each Fixed Conversion Rate as set forth in “—Anti-dilution Adjustments.”

The following table sets forth the Fundamental Change Conversion Rate per share of the Mandatory Convertible Preferred Stock for each Fundamental Change Share Price and Fundamental Change Effective Date set forth below:

The exact Fundamental Change Share Price and Fundamental Change Effective Date may not be set forth in the table, in which case:

Fundamental Change Dividend Make-whole Amount and Accumulated Dividend Amount

For any shares of Mandatory Convertible Preferred Stock that are converted during the Fundamental Change Conversion Period, in addition to the Class B common stock issued upon conversion at the Fundamental Change Conversion Rate, we will at our option (subject to satisfaction of the requirements described below):

S-37

In addition, to the extent that the Accumulated Dividend Amount exists as of the Fundamental Change Effective Date and subject to the limitations described below, holders who convert their Mandatory Convertible Preferred Stock within the Fundamental Change Conversion Period will be entitled to receive such Accumulated Dividend Amount upon conversion. As used herein, the term “Accumulated Dividend Amount” means, in connection with a Fundamental Change, the aggregate amount of accumulated and unpaid dividends, if any, for dividend periods prior to the relevant Fundamental Change Effective Date, including for the partial dividend period, if any, from, and including, the Dividend Payment Date immediately preceding such Fundamental Change Effective Date to, but excluding, such Fundamental Change Effective Date. The Accumulated Dividend Amount will be payable at our election (subject to satisfaction of the requirements described below):

We will pay the Fundamental Change Dividend Make-whole Amount and the Accumulated Dividend Amount in cash, except to the extent we elect on or prior to the second Business Day following the Fundamental Change Effective Date to make all or any portion of such payments in shares of our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below). Any such payment in cash may not be permitted by the terms of any of our and our subsidiaries’ then-existing indebtedness.

If we elect to deliver shares of our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below) in respect of all or any portion of the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount, to the extent that the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount (or, if applicable, the dollar amount of any portion thereof paid in Class B common stock (or, to the extent applicable, Units of Exchange Property as described below)) exceeds the product of the number of additional shares of our Class B common stock we deliver in respect thereof and 97% of the Fundamental Change Share Price, we will, if we are able to do so under applicable Delaware law, pay such excess amount in cash (computed to the nearest cent). Any such payment in cash may not be permitted by the terms of any of our and our subsidiaries’ then-existing indebtedness. To the extent that we are not able to pay such excess amount in cash under applicable Delaware law, we will not have any obligation to pay such amount in cash or deliver additional shares of our Class B common stock in respect of such amount.

No fractional shares of our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below) will be delivered to converting holders of the Mandatory Convertible Preferred Stock in respect of the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount. We will instead, to the extent legally permissible and in compliance with the terms of any of our and our subsidiaries’ then-existing indebtedness, pay a cash adjustment (computed to the nearest cent) to each converting holder that would otherwise be entitled to a fraction of a share of our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below) based on the Average VWAP per share of our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below) over the five consecutive Trading Day period ending on, and including, the second Trading Day immediately preceding the relevant conversion date. In the event that we cannot pay cash in lieu of a fractional share, we will instead round up to the

S-38

nearest whole share for each holder. The terms of any of our and our subsidiaries’ then-existing indebtedness may not permit the payment of a cash amount in lieu of a fractional share.

However, if we are prohibited from paying or delivering, as the case may be, the Fundamental Change Dividend Make-whole Amount (whether in cash or in shares of our Class B common stock), in whole or in part, due to the limitations of applicable Delaware law, the Fundamental Change Conversion Rate will instead be increased by a number of shares of Class B common stock equal to the cash amount of the aggregate unpaid and undelivered Fundamental Change Dividend Make-whole Amount, divided by the greater of (i) the Floor Price and (ii) 97% of the Fundamental Change Share Price. To the extent that the cash amount of the aggregate unpaid and undelivered Fundamental Change Dividend Make-whole Amount exceeds the product of such number of additional shares and 97% of the Fundamental Change Share Price, we will not have any obligation to pay the shortfall in cash or deliver additional shares of our Class B common stock in respect of such amount.

As soon as reasonably practical and in any event not later than the second Business Day following the Fundamental Change Effective Date, we will notify holders of:

Our obligation to deliver shares at the Fundamental Change Conversion Rate and pay the Fundamental Change Dividend Make-whole Amount (whether in cash, our Class B common stock (or, to the extent applicable, Units of Exchange Property as described below) or any combination thereof) could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies and therefore may not be enforceable in whole or in part.

Conversion Procedures

Upon Mandatory Conversion

Any outstanding shares of Mandatory Convertible Preferred Stock will automatically convert into shares of Class B common stock on the Mandatory Conversion Date.

If more than one share of the Mandatory Convertible Preferred Stock held by the same holder is automatically converted on the Mandatory Conversion Date, the number of shares of our Class B common stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Mandatory Convertible Preferred Stock so converted (or, in the case of Mandatory Convertible Preferred Stock held through the facilities of DTC, based on such aggregate number of shares of the Mandatory Convertible Preferred Stock so converted as may be required by DTC or its nominee pursuant to DTC’s applicable procedures).

You will not be required to pay any transfer taxes or duties relating to the issuance or delivery of our Class B common stock upon conversion, but you will be required to pay any tax or duty that may be payable relating to any transfer involved in the issuance or delivery of the Class B common stock in a name other than your own.

So long as the shares of the Mandatory Convertible Preferred Stock being converted are in global form, the shares of Class B common stock issuable upon conversion will be delivered to the converting holder through the

S-39

facilities of DTC, in each case together with delivery by the Company to the converting holder of any cash to which the converting holder is entitled, on the later of (i) the Mandatory Conversion Date and (ii) the Business Day after the converting holder has paid in full all applicable taxes and duties, if any.

The person or persons entitled to receive the shares of our Class B common stock issuable upon mandatory conversion of the Mandatory Convertible Preferred Stock will be treated as the record holder(s) of such shares as of the close of business on the Mandatory Conversion Date. Except as provided in “—Anti-dilution Adjustments,” prior to the close of business on the Mandatory Conversion Date, the Class B common stock issuable upon conversion of the Mandatory Convertible Preferred Stock will not be deemed to be outstanding for any purpose and you will have no rights, powers, preferences or privileges with respect to such Class B common stock, including rights to respond to tender offers and rights to receive any dividends or other distributions on the Class B common stock, issuable in respect thereof by virtue of holding the Mandatory Convertible Preferred Stock.

Upon Early Conversion or Upon a Conversion in Connection with a Fundamental Change

If a holder elects to convert the Mandatory Convertible Preferred Stock prior to April 1, 2024, in the manner described in “—Early Conversion at the Option of the Holder” or “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-whole Amount,” you must observe the following conversion procedures:

The “conversion date” will be the date on which you have satisfied the foregoing requirements, to the extent applicable.

If more than one share of the Mandatory Convertible Preferred Stock is surrendered for conversion at one time by or for the same holder, the number of shares of our Class B common stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Mandatory Convertible Preferred Stock so surrendered (or, in the case of Mandatory Convertible Preferred Stock held through the facilities of DTC, based on such aggregate number of shares of the Mandatory Convertible Preferred Stock so converted as may be required by DTC or its nominee pursuant to DTC’s applicable procedures).

You will not be required to pay any taxes or duties relating to the issuance or delivery of our Class B common stock upon conversion, but you will be required to pay any tax or duty that may be payable relating to any transfer involved in the issuance or delivery of the Class B common stock in a name other than your own.

So long as the shares of the Mandatory Convertible Preferred Stock being converted are in global form, the shares of Class B common stock will be issued and delivered to the converting holder through the facilities of DTC on the latest of (i) the second Business Day immediately succeeding the conversion date, (ii) the second Business Day immediately succeeding the last day of the Early Conversion Settlement Period and (iii) the Business Day after you have paid in full all applicable taxes and duties, if any.

The person or persons entitled to receive the Class B common stock issuable upon early conversion of the Mandatory Convertible Preferred Stock will be treated as the record holder(s) of such shares as of the close of business on the applicable Early Conversion Date or Fundamental Change Conversion Date. Except as provided in “—Anti-dilution Adjustments,” prior to the close of business on the applicable Early Conversion Date or Fundamental Change Conversion Date, the Class B common stock issuable upon early conversion of the

S-40

Mandatory Convertible Preferred Stock will not be outstanding, or deemed to be outstanding, for any purpose and you will have no rights, powers, preferences or privileges with respect to such Class B common stock, including rights to respond to tender offers and rights to receive any dividends or other distributions on the Class B common stock, by virtue of holding the Mandatory Convertible Preferred Stock.

Fractional Shares

No fractional shares of our Class B common stock will be issued to holders of the Mandatory Convertible Preferred Stock upon conversion. In lieu of any fractional shares of our Class B common stock otherwise issuable in respect of the aggregate number of shares of the Mandatory Convertible Preferred Stock of any holder that are converted, that holder will be entitled to receive an amount in cash (computed to the nearest cent) equal to the product of: (i) that same fraction; and (ii) the Average VWAP of our Class B common stock over the five consecutive Trading Day period ending on, and including, the second Trading Day immediately preceding the relevant conversion date. In the event that we cannot pay cash in lieu of a fractional share, we will instead round up to the nearest whole share of Class B common stock for each holder. The terms of any of our and our subsidiaries’ then-existing indebtedness may not permit the payment of a cash amount in lieu of a fractional share.

Anti-dilution Adjustments

Each Fixed Conversion Rate will be adjusted as described below, except that we will not make any adjustments to the Fixed Conversion Rates if holders of the Mandatory Convertible Preferred Stock participate (other than in the case of a share split or share combination or a tender or exchange offer described in clause (5) below), at the same time and upon the same terms as holders of our Class B common stock and solely as a result of holding the Mandatory Convertible Preferred Stock, in any of the transactions described below and without having to convert their Mandatory Convertible Preferred Stock as if they held a number of shares of Class B common stock equal to (i) the Maximum Conversion Rate as of the record date for such transaction, multiplied by (ii) the number of shares of Mandatory Convertible Preferred Stock held by such holder.

where,

Any adjustment made under this clause (1) shall become effective immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date

S-41

for such share split or share combination, as applicable. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a duly authorized committee thereof determines not to pay such dividend or distribution, to such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the purposes of this clause (1), the number of shares of our Class B common stock outstanding immediately prior to the close of business on the relevant record date or immediately prior to the open of business on the relevant effective date, as the case may be, and the number of shares of our Class B common stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination shall, in each case, not include shares that we hold in treasury. We will not pay any dividend or make any distribution on shares of our Class B common stock that we hold in treasury.

“Effective date” as used in this clause (1) means the first date on which the shares of our Class B common stock trade on the Relevant Stock Exchange, regular way, reflecting the relevant share split or share combination, as applicable.

“Record date” means, with respect to any dividend, distribution or other transaction or event in which the holders of our Class B common stock (or other applicable security) have the right to receive any cash, securities or other property or in which our Class B common stock (or such other security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of our Class B common stock (or such other security) entitled to receive such cash, securities or other property (whether such date is fixed by our board of directors or a duly authorized committee thereof, statute, contract or otherwise).

where,

Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the record date for such

S-42

issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Class B common stock are not delivered after the exercise of such rights, options or warrants, each Fixed Conversion Rate shall be decreased to such Fixed Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Class B common stock actually delivered, if any. If such rights, options or warrants are not so issued, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a duly authorized committee thereof determines not to issue such rights, options or warrants, to such Fixed Conversion Rate that would then be in effect if such record date for such issuance had not occurred.

For the purpose of this clause (2), in determining whether any rights, options or warrants entitle the holders of our Class B common stock to subscribe for or purchase shares of our Class B common stock at less than such Average VWAP per share for the ten consecutive trading day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of our Class B common stock, there shall be taken into account any consideration received by us for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by our board of directors or a duly authorized committee thereof in good faith.

where,

S-43

“Ex-date” means the first date on which the shares of our Class B common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question, from us or, if applicable, from the seller of our Class B common stock on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market.

Any increase made under the portion of this clause (3) above will become effective immediately after the close of business on the record date for such distribution. If such distribution is not so paid or made, each Fixed Conversion Rate shall be immediately readjusted, effective as of the date our board of directors or a duly authorized committee thereof determines not to pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), or if the difference is less than $1.00, in lieu of the foregoing increase, each holder shall receive, in respect of each share of Mandatory Convertible Preferred Stock, at the same time and upon the same terms as holders of our Class B common stock, the amount and kind of our capital stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our capital stock or other securities that such holder would have received if such holder owned a number of shares of Class B common stock equal to the Maximum Conversion Rate in effect on the record date for the distribution.

If we issue rights, options or warrants that are only exercisable upon the occurrence of certain triggering events, then:

With respect to an adjustment pursuant to this clause (3) where there has been a payment of a dividend or other distribution on our Class B common stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange, which we refer to as a “spin-off,” each Fixed Conversion Rate will be increased based on the following formula:

where,

S-44

The increase to each Fixed Conversion Rate under the preceding paragraph will be calculated as of the close of business on the last Trading Day of the valuation period but will be given retroactive effect as of immediately after the open of business on the ex-date of the spin-off. Because we will make the adjustment to each Fixed Conversion Rate with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Stock where any date for determining the number of shares of our Class B common stock issuable to a holder occurs during the valuation period until the second Business Day after the last Trading Day of such valuation period. If such dividend or distribution is not so paid, each Fixed Conversion Rate shall be decreased, effective as of the date our board of directors or a duly authorized committee thereof determines not to make or pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

where,

The Initial Dividend Threshold will be subject to adjustment in a manner inversely proportional to adjustments to the Fixed Conversion Rate; provided that no adjustment will be made to the Initial Dividend Threshold for any adjustment to the Fixed Conversion Rate under this clause (4).

Any increase made under this clause (4) shall become effective immediately after the close of business on the record date for such dividend or distribution. If such dividend or distribution is not so paid, each Fixed Conversion Rate shall be decreased, effective as of the date our board of directors or a duly authorized committee thereof determines not to make or pay such dividend or distribution, to be such Fixed Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), or if the difference is less than $1.00, in lieu of the foregoing increase, each holder shall receive, in respect of each share of Mandatory Convertible Preferred Stock, at the same time and upon the same terms as holders of shares of our Class B common stock, the amount of cash that such holder would have received if such holder owned a number of shares of our Class B common stock equal to the Maximum Conversion Rate on the record date for such cash dividend or distribution.

S-45

where,

The increase to each Fixed Conversion Rate under the preceding paragraph will be calculated at the close of business on the last Trading Day of the averaging period but will be given retroactive effect as of immediately after the close of business on the expiration date. Because we will make the adjustment to each Fixed Conversion Rate with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Stock where any date for determining the number of shares of our Class B common stock issuable to a holder occurs during the averaging period until the second Business Day after the last Trading Day of such averaging period. For the avoidance of doubt, no adjustment under this clause (5) will be made if such adjustment would result in a decrease in any Fixed Conversion Rate.

In the event that we or one of our subsidiaries is obligated to purchase shares of Class B common stock pursuant to any such tender offer or exchange offer, but we or such subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then each Fixed Conversion Rate shall again be adjusted to be such Fixed Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made (or had been made only in respect of the purchases that have been made and not rescinded).

We may, to the extent permitted by law and the rules of The Nasdaq Global Select Market or any other securities exchange on which our Class B common stock or the Mandatory Convertible Preferred Stock is then listed, increase each Fixed Conversion Rate by any amount for a period of at least 20 Business Days if such

S-46

increase is irrevocable during such 20 Business Days and our board of directors (or a duly authorized committee thereof) determines that such increase would be in our best interest. In addition, we may make such increases in each Fixed Conversion Rate as we deem advisable in order to avoid or diminish any income tax to holders of our Class B common stock resulting from any dividend or distribution of shares of our Class B common stock (or issuance of rights or warrants to acquire shares of our Class B common stock) or from any event treated as such for income tax purposes or for any other reason. We may only make such a discretionary adjustment if we make the same proportionate adjustment to each Fixed Conversion Rate.

Holders of the Mandatory Convertible Preferred Stock may, in certain circumstances, including a distribution of cash dividends to holders of our shares of Class B common stock, be deemed to have received a distribution subject to U.S. Federal income tax as a dividend as a result of an adjustment or the nonoccurrence of an adjustment to the Fixed Conversion Rates. See “Material U.S. Federal Income Tax Considerations.”

If we have a rights plan in effect upon conversion of the Mandatory Convertible Preferred Stock into Class B common stock, you will receive, in addition to any shares of Class B common stock received in connection with such conversion, the rights under the rights plan. However, if, prior to any conversion, the rights have separated from the shares of Class B common stock in accordance with the provisions of the applicable rights plan, each Fixed Conversion Rate will be adjusted at the time of separation as if we distributed to all or substantially all holders of our Class B common stock, shares of our capital stock, evidences of indebtedness, assets, property, rights, options or warrants as described in clause (3) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. We do not currently have a stockholder rights plan in effect.

Adjustments to the Fixed Conversion Rates will be calculated to the nearest 1/10,000th of a share of our Class B common stock. No adjustment to any Fixed Conversion Rate will be required unless the adjustment would require an increase or decrease of at least 1% to each of the Fixed Conversion Rates; provided, however, that if an adjustment is not made because the adjustment does not change each of the Fixed Conversion Rates by at least 1%, then such adjustment will be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, on each date for determining the number of shares of our Class B common stock issuable to a holder upon any conversion of the Mandatory Convertible Preferred Stock, and on each Trading Day during the Settlement Period or any other valuation period in connection with a conversion of the Mandatory Convertible Preferred Stock, we will give effect to all adjustments that we have otherwise deferred pursuant to this sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment.

The Fixed Conversion Rates will not be adjusted:

S-47

Except as otherwise provided above, we will be responsible for making all calculations called for under the Mandatory Convertible Preferred Stock. These calculations include, but are not limited to, determinations of the Fundamental Change Share Price, the VWAPs, the Average VWAPs and the Fixed Conversion Rates of the Mandatory Convertible Preferred Stock.

We will be required, within ten Business Days after the Fixed Conversion Rates are adjusted, to provide or cause to be provided written notice of the adjustment to the holders of the Mandatory Convertible Preferred Stock. We will also be required to deliver a statement setting forth in reasonable detail the method by which the adjustment to each Fixed Conversion Rate was determined and setting forth each adjusted Fixed Conversion Rate.

For the avoidance of doubt, if an adjustment is made to the Fixed Conversion Rates, no separate inversely proportionate adjustment will be made to the Initial Price or the Threshold Appreciation Price because the Initial Price is equal to $100.00 divided by the Maximum Conversion Rate (as adjusted in the manner described herein) and the Threshold Appreciation Price is equal to $100.00 divided by the Minimum Conversion Rate (as adjusted in the manner described herein).

Whenever the terms of the Mandatory Convertible Preferred Stock require us to calculate the VWAP per share of our Class B common stock over a span of multiple days, our board of directors or a duly authorized committee thereof will make appropriate adjustments in good faith (including, without limitation, to the Applicable Market Value, the Early Conversion Average Price, the Fundamental Change Share Price and the Average Price (as the case may be)) to account for any adjustments to the Fixed Conversion Rates (as the case may be) that become effective, or any event that would require such an adjustment if the record date, ex-date, effective date or Expiration Date (as the case may be) of such event occurs, during the relevant period used to calculate such prices or values (as the case may be).

If:

then we will deem the holders of the Mandatory Convertible Preferred Stock to be holders of record of our Class B common stock for purposes of that dividend or distribution. In this case, the holders of the Mandatory Convertible Preferred Stock would receive the dividend or distribution on our Class B common stock together with the number of shares of our Class B common stock issuable upon mandatory conversion of the Mandatory Convertible Preferred Stock.

Recapitalizations, Reclassifications and Changes of Our Class B Common Stock

In the event of:

S-48

The number of Units of Exchange Property we will deliver upon conversion of each share of Mandatory Convertible Preferred Stock or as a payment of dividends on the Mandatory Convertible Preferred Stock, as applicable, following the effective date of such Reorganization Event will be determined as if references to our Class B common stock in the description of the conversion rate applicable upon mandatory conversion, conversion at the option of the holder or conversion at the option of the holder upon a Fundamental Change and/or the description of the relevant dividend payment provisions, as the case may be, were to Units of Exchange Property (without interest thereon and without any right to dividends or distributions thereon which have a record date prior to the date on which holders of the Mandatory Convertible Preferred Stock become holders of record of the underlying shares of our Class B common stock). For the purpose of determining which bullet of the definition of conversion rate in the second paragraph under “—Mandatory Conversion” will apply upon mandatory conversion, and for the purpose of calculating the conversion rate if the second bullet is applicable, the value of a Unit of Exchange Property will be determined in good faith by our board of directors or a duly authorized committee thereof (which determination will be final), except that if a Unit of Exchange Property includes common stock or American Depositary Receipts (“ADRs”) that are traded on a U.S. national securities exchange, the value of such common stock or ADRs will be the average over the 20 consecutive Trading Day period used for calculating the Applicable Market Value of the volume-weighted average prices for such common stock or ADRs, as displayed on the applicable Bloomberg screen (as determined in good faith by our board of directors or a duly authorized committee thereof (which determination will be final)); or, if such price is not available, the average market value per share of such common stock or ADRs over such period as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose. The provisions of this paragraph will apply to successive Reorganization Events, and the provisions summarized under “—Anti-dilution Adjustments” will apply to any shares of common equity or ADRs of us or any successor received by the holders of shares of our common stock in any such Reorganization Event. We (or any successor to us) will, as soon as reasonably practicable (but in any event within 20 calendar days) after the occurrence of any Reorganization Event provide written notice to the holders of the Mandatory Convertible Preferred Stock of such occurrence and of the kind and amount of cash,

S-49

securities or other property that constitute the Exchange Property. Failure to deliver such notice will not affect the operation of the provisions described in this section.

It is possible that certain consolidations, mergers, combinations or other transactions could result in tax gains or losses to the holders either as a result of the transaction or the conversion thereafter. Holders are encouraged to consult with their own tax advisors regarding the tax consequences of the ownership, disposition and conversion of the Mandatory Convertible Preferred Stock.

Reservation of Shares

We will at all times reserve and keep available out of the authorized and unissued shares of Class B common stock, solely for issuance upon conversion of the Mandatory Convertible Preferred Stock, the maximum number of shares of our Class B common stock as shall be issuable from time to time upon the conversion of all the shares of the Mandatory Convertible Preferred Stock then outstanding (assuming, for such purposes, the maximum increase in the conversion rate in connection with the Mandatory Conversion Additional Conversion Amount).

Transfer Agent, Registrar and Conversion and Dividend Disbursing Agent

Equiniti Trust Company is the transfer agent and registrar of our common stock and will serve as transfer agent, registrar, conversion and dividend disbursing agent for the Mandatory Convertible Preferred Stock.

Book-Entry, Delivery and Form

The Mandatory Convertible Preferred Stock will be issued in global form. DTC or its nominee will be the sole registered holder of the Mandatory Convertible Preferred Stock. Ownership of beneficial interests in the Mandatory Convertible Preferred Stock in global form will be limited to persons who have accounts with DTC (“participants”) or persons who hold interests through such participants. Ownership of beneficial interests in the Mandatory Convertible Preferred Stock in global form will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants).

So long as DTC, or its nominee, is the registered owner or holder of a global certificate representing the shares of the Mandatory Convertible Preferred Stock, DTC or such nominee, as the case may be, will be considered the sole holder of the shares of the Mandatory Convertible Preferred Stock represented by such global certificate for all purposes under the Certificate of Designations establishing the terms of the Mandatory Convertible Preferred Stock. No beneficial owner of an interest in the shares of the Mandatory Convertible Preferred Stock in global form will be able to transfer that interest except in accordance with the applicable procedures of DTC in addition to those provided for under the Certificate of Designations establishing the terms of the Mandatory Convertible Preferred Stock.

Payments of dividends on the global certificate representing the shares of the Mandatory Convertible Preferred Stock will be made to DTC or its nominee, as the case may be, as the registered holder thereof. None of us, the transfer agent, registrar, conversion or dividend disbursing agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global certificate representing the shares of the Mandatory Convertible Preferred Stock or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that DTC or its nominee, upon receipt of any payment of dividends in respect of a global certificate representing the shares of the Mandatory Convertible Preferred Stock, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial ownership interests in the aggregate Liquidation Preference of such global certificate representing the shares of the Mandatory Convertible

S-50

Preferred Stock as shown on the records of DTC or its nominee, as the case may be. We also expect that payments by participants to owners of beneficial interests in such global certificate representing the shares of the Mandatory Convertible Preferred Stock held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. We understand that DTC is:

DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include:

Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (indirect participants).

Although DTC is expected to follow the foregoing procedures in order to facilitate transfers of interests in a global security among its participants, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of us, the transfer agent, registrar, conversion or dividend disbursing agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

If DTC is at any time unwilling or unable to continue as a depositary for the shares of the Mandatory Convertible Preferred Stock in global form or DTC ceases to be registered as a clearing agency under the Exchange Act, and in either case a successor depositary is not appointed by us within 90 days, we will issue certificated shares in exchange for the global securities. Beneficial interests in Mandatory Convertible Preferred Stock in global form held by any direct or indirect participant may also be exchanged for certificated shares upon request to DTC by such direct participant (for itself or on behalf of an indirect participant), to the transfer agent in accordance with their respective customary procedures.

The information in this section concerning DTC and its book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a general summary of the material U.S. federal income tax consequences of the purchase, ownership, disposition and conversion of our Mandatory Convertible Preferred Stock and any Class B common stock received in respect of our Mandatory Convertible Preferred Stock. This summary does not purport to be a comprehensive description of all the potential tax considerations that may be relevant to a holder’s decision to purchase our Mandatory Convertible Preferred Stock, including tax consequences that arise from rules of general application to all taxpayers or certain classes of taxpayers. This summary is based upon the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations (including proposed Treasury regulations) promulgated thereunder, administrative rulings and judicial decisions, each as of the date hereof. These authorities may be changed, or subject to differing interpretations, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to the matters discussed below, and there can be no assurance that the IRS or a court will not take a contrary position regarding the tax consequences of the purchase, ownership, disposition or conversion of our Mandatory Convertible Preferred Stock or our Class B common stock.

This summary assumes that our Mandatory Convertible Preferred Stock and shares of our Class B common stock will be held as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxes that may be relevant to holders in light of their particular circumstances, does not discuss the potential application of the Medicare surtax on net investment income and the alternative minimum tax and does not deal with state or local taxes, U.S. federal gift and estate tax laws or any non-U.S. tax consequences. In addition, this discussion does not address all tax considerations that may be applicable to a holder’s particular circumstances or to holders that may be subject to special tax rules, including, without limitation:

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our Mandatory Convertible Preferred Stock or our Class B common stock that is, for U.S. federal income tax purposes:

S-52

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of our Mandatory Convertible Preferred Stock or our Class B common stock that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Mandatory Convertible Preferred Stock or our Class B common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the activities of the partnership and the status of the partner. Prospective investors that are partners in partnerships (or entities or arrangements treated as partnerships for U.S. federal income tax purposes) should consult their tax advisors regarding the U.S. federal income tax consequences to them of the purchase, ownership, disposition and conversion of our Mandatory Convertible Preferred Stock or our Class B common stock.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, CONVERSION (IN THE CASE OF OUR MANDATORY CONVERTIBLE PREFERRED STOCK), AND DISPOSITION OF OUR MANDATORY CONVERTIBLE PREFERRED STOCK OR OUR CLASS B COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Tax Considerations Applicable to U.S. Holders

Distributions

Distributions in cash paid on our Mandatory Convertible Preferred Stock or our Class B common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Subject to applicable limitations and restrictions, dividends paid to non-corporate U.S. Holders will be treated as “qualified dividend income” (as defined in the Code) taxable at favorable rates applicable to long-term capital gains. Subject to applicable limitations and restrictions, dividends paid to corporate U.S. Holders will be eligible for the dividends-received deduction. U.S. Holders should consult their tax advisors regarding the application of reduced tax rates and the dividends-received deduction in their particular circumstances. If the amount of a distribution exceeds our current and accumulated earnings and profits, the excess will be allocated ratably among each share of our Mandatory Convertible Preferred Stock or our Class B common stock, as the case may be, and such excess will be treated as a tax-free return of the U.S. Holder’s investment, up to such holder’s tax basis in our Mandatory Convertible Preferred Stock or our Class B common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below under the heading “—Sale or Other Taxable Disposition.”

If we make a distribution on our Mandatory Convertible Preferred Stock in the form of our Class B common stock, although there is some uncertainty, we believe that such distribution will be taxable for U.S. federal income tax purposes in the same manner as cash distributions described above. The amount of such distribution and a U.S. Holder’s tax basis in such Class B common stock will equal the fair market value of such Class B

S-53

common stock on the distribution date, and a U.S. Holder’s holding period for such Class B common stock will begin on the day following the distribution date. Because such distribution would not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because such U.S. Holder failed to establish an exemption from backup withholding), we expect that the applicable withholding agent will withhold such taxes from shares of Class B common stock or current or subsequent payments of cash to such U.S. Holder. U.S. Holders should consult with their tax advisors regarding the tax consequences of a Class B common stock distribution on our Mandatory Convertible Preferred Stock.

Extraordinary Dividends

A dividend that equals or exceeds certain thresholds (generally 5% of a U.S. Holder’s tax basis in a share of our Mandatory Convertible Preferred Stock or 10% of a U.S. Holder’s tax basis in a share of our Class B common stock, in each case, treating all dividends having ex-dividend dates within an 85-day period as a single dividend) could be characterized as an “extraordinary dividend” under the Code. A corporate U.S. Holder that has held our Mandatory Convertible Preferred Stock or Class B common stock for two years or less before the dividend announcement date and that receives an extraordinary dividend generally will be required to reduce its tax basis in the stock with respect to which such dividend was made by the nontaxed portion of such dividend. If the amount of the reduction exceeds the U.S. Holder’s tax basis in such stock, the excess is taxable as capital gain realized on the sale or other disposition of our Mandatory Convertible Preferred Stock or Class B common stock and will be treated as described under “—Sale or Other Taxable Disposition” below. A non-corporate U.S. Holder that receives an extraordinary dividend generally will be required to treat any loss on the sale of our Mandatory Convertible Preferred Stock or Class B common stock as long-term capital loss to the extent of the extraordinary dividends the U.S. Holder receives that qualify for taxation at the reduced rates discussed above under “—Distributions.”

Adjustments to Conversion Rate

The conversion rate of our Mandatory Convertible Preferred Stock is subject to adjustment under specified circumstances. A U.S. Holder of our Mandatory Convertible Preferred Stock will be treated as having received a deemed distribution includable in such U.S. Holder’s income in the manner described under “—Distributions,” above, if and to the extent that certain adjustments in the conversion rate increase the proportionate interest of the U.S. Holder in our assets or earnings and profits. In addition, the failure to make certain adjustments on our Mandatory Convertible Preferred Stock may cause a U.S. Holder of our Class B common stock to be deemed to have received a constructive distribution from us, even though the U.S. Holder has not received any cash or property as a result of such adjustments. Adjustments to the conversion rate made pursuant to a bona fide reasonable adjustment formula which has the effect of preventing the dilution of the interest of the holders of our Mandatory Convertible Preferred Stock generally will not be deemed to result in a constructive distribution. Certain of the possible adjustments in the terms of our Mandatory Convertible Preferred Stock (including, without limitation, adjustments in respect of taxable dividends to our Class B common stockholders) may not qualify as being made pursuant to a bona fide reasonable adjustment formula.

If an adjustment that does not qualify as being pursuant to a bona fide reasonable adjustment formula is made, a U.S. Holder of our Mandatory Convertible Preferred Stock will be deemed to have received a constructive distribution from us, even though such U.S. Holder has not received any cash or property as a result of such adjustment. The tax consequences of the receipt of a distribution from us are described above under “—Distributions.” Because constructive distributions deemed received by a U.S. Holder would not give rise to any cash from which any applicable withholding could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because the U.S. Holder failed to establish an exemption from backup withholding), we expect that the applicable withholding agent will withhold such taxes from payments of cash or shares of Class B common stock payable to the U.S. Holder.

S-54

Under rules currently in effect, we are generally required to report the amount of any deemed distributions on our website or to the IRS and to holders of our Mandatory Convertible Preferred Stock not exempt from reporting. The IRS has proposed regulations addressing the amount and timing of constructive distributions as well as obligations of withholding agents and filing and notice obligations of the issuers in respect of such constructive distributions. If adopted as proposed, the regulations would generally provide, among other things, that (i) the amount of a constructive distribution is the excess of the fair market value of the right to acquire Class B common stock immediately after the conversion rate adjustment over the fair market value of the right to acquire Class B common stock (determined immediately after the conversion rate adjustment) without the adjustment, and (ii) the constructive distribution occurs at the earlier of the date the adjustment occurs under the terms of our Mandatory Convertible Preferred Stock and the date of the actual distribution of cash or property that results in the constructive distribution. The final regulations will be effective for deemed distributions occurring on or after the date of adoption, but holders of our Mandatory Convertible Preferred Stock and withholding agents may rely on them prior to that date under certain circumstances.

Sale or Other Taxable Disposition

Upon the sale or other taxable disposition of our Mandatory Convertible Preferred Stock (other than pursuant to a conversion into Class B common stock described below) or Class B common stock, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s adjusted tax basis in such shares. Gain or loss realized on the sale or other disposition generally will be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other disposition our Mandatory Convertible Preferred Stock or our Class B common stock has been held for more than one year. For non-corporate taxpayers, long-term capital gains are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Conversion of Mandatory Convertible Preferred Stock into Class B Common Stock

A U.S. Holder generally will not recognize gain or loss upon the conversion of our Mandatory Convertible Preferred Stock into shares of our Class B common stock, except that any cash or Class B common stock received in respect of accrued and unpaid dividends that have been declared will be taxable as described above under “—Distributions,” with any Class B common stock received in respect of such dividends treated as if the U.S. Holder had received an amount of cash equal to the fair market value of any such Class B common stock determined as of the date of conversion. In addition, a U.S. Holder’s receipt of cash in lieu of a fractional share of our Class B common stock will generally result in capital gain or loss (measured by the difference between the cash received in lieu of the fractional share of our Class B common stock and the U.S. Holder’s tax basis allocable to the fractional share).

The tax treatment of a U.S. Holder’s receipt of any cash or Class B common stock paid upon conversion in respect of accrued and unpaid dividends that have not been declared, or paid in respect of any Fundamental Change Dividend Make-Whole Amount, is uncertain. In particular, amounts of cash and Class B common stock received in respect of accrued and unpaid dividends that have not been declared may be treated as deemed distributions, as described above under “—Distributions,” to the extent that (i) our Mandatorily Convertible Preferred Stock is treated as preferred stock for purposes of the Treasury regulations addressing deemed distributions and (ii) the fair market value of the cash and Class B common stock received upon conversion exceeds the issue price paid by the U.S. Holder for the Mandatory Convertible Preferred Stock surrendered. Although not free from doubt, we believe the receipt of such cash or Class B common stock in respect of such amounts should be treated as additional consideration received by the U.S. Holder upon conversion of our Mandatory Convertible Preferred Stock into shares of our Class B common stock (and not as a deemed distribution). Accordingly, in the event we choose to pay solely Class B common stock in respect of such amounts, the receipt of such stock should be taxed as described in the preceding paragraph. In the event a U.S. Holder converts its Mandatory Convertible Preferred Stock and we pay such holder cash or a combination of cash and Class B common stock in respect of such amounts, the conversion should be taxable to the extent of the

S-55

lesser of the cash received (other than cash received in respect of a fractional share of Class B common stock) and any gain realized by the U.S. Holder. For this purpose, gain realized generally would equal the excess, if any, of (i) the amount of cash and the fair market value of our Class B common stock received upon conversion (including any fractional shares of our Class B common stock for which cash is received) over (ii) the U.S. Holder’s tax basis in its shares of our Mandatory Convertible Preferred Stock immediately prior to conversion. The character of such gain recognized (which will be the lesser of such gain and such cash) is uncertain. If the receipt of such cash is considered to have the effect of a dividend (which generally would be the case if the receipt of such cash did not result in a meaningful reduction in such U.S. Holder’s equity interest in us, as determined for U.S. federal income tax purposes), such gain (to the extent recognized) will be taxable as dividend income, to the extent of the U.S. Holder’s allocable share of our current and accumulated earnings and profits. Alternatively, such gain could be capital gain. To the extent the amount of cash received in respect of accrued but unpaid dividends that have not been declared, or in respect of any Fundamental Change Dividend Make-Whole Amount, exceeds the gain realized by a U.S. Holder, the excess amount will not be taxable to such U.S. Holder but will reduce its adjusted tax basis in our Class B common stock received.

U.S. Holders should be aware that the tax treatment described above in respect of the payments of cash or Class B common stock made in respect of accrued and unpaid dividends that have not been declared and any Fundamental Change Dividend Make-Whole Amount is not certain and may be challenged by the IRS, including on grounds that the amount of cash and fair market value of our Class B Common Stock received attributable to the accrued and unpaid dividends that have not been declared and any Fundamental Change Dividend Make-Whole Amount represents a taxable dividend to the extent we have earnings and profits at the time of conversion, as described above under “—Distributions.”

Because payments of Class B common stock that are treated as dividends will not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay backup withholding on behalf of a U.S. Holder (because such U.S. Holder failed to establish an exemption from backup withholding), we expect that the applicable withholding agent will withhold such taxes from shares of Class B common stock or current or subsequent payments of cash to such U.S. Holder.

Except as discussed in the paragraph below, a U.S. Holder’s tax basis in shares of Class B common stock received upon conversion of our Mandatory Convertible Preferred Stock (and any fractional shares of our Class B common stock treated as received and then exchanged for cash) will equal the adjusted tax basis of the converted shares of our Mandatory Convertible Preferred Stock, increased by any gain recognized on the conversion and reduced by any cash received that was treated as additional consideration received in the conversion as discussed above, and the holding period of such shares of Class B common stock will include the holding period of the converted shares of our Mandatory Convertible Preferred Stock. A U.S. Holder’s tax basis in Class B common stock received may be further reduced under the rules described above under “—Extraordinary Dividends.” Class B Common stock received in payment of accrued but unpaid dividends that have been declared and taxed as a dividend upon receipt, if any, will have a tax basis equal to their fair market value on the date of conversion, and a new holding period which will commence on the day after the conversion.

In the event a U.S. Holder’s Mandatory Convertible Preferred Stock is converted or exchanged into shares of preferred stock of a successor entity pursuant to certain transactions (including our consolidation or merger into another person), the tax treatment of such a conversion or exchange will depend upon the facts underlying the particular transaction triggering such a conversion. U.S. Holders should consult their tax advisors to determine the specific tax treatment of a conversion under such circumstances.

Information Reporting and Backup Withholding

Generally, information reporting will apply to the payment of distributions (including constructive distributions) on our Mandatory Convertible Preferred Stock or our Class B common stock and the proceeds from a sale or other disposition of such stock, unless the U.S. Holder is an exempt recipient (such as a

corporation). Backup withholding may apply to such payments if a U.S. Holder fails to provide a correct taxpayer identification number or a certification of exempt status or fails to report in full dividend and interest income. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a U.S. Holder’s U.S. federal income tax liability; provided that the required information is timely furnished to the IRS.

Tax Considerations Applicable to Non-U.S. Holders

Distributions

Subject to the discussion below of effectively connected income, distributions or other payments that are treated as dividends (see “—Tax Considerations Applicable to U.S. Holders—Distributions” and “—Conversion of Mandatory Convertible Preferred Stock into Class B Common Stock” above), including deemed distributions described above under “—Tax Considerations Applicable to U.S. Holders—Adjustments to Conversion Rate,” generally will be subject to withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such Non-U.S. Holder’s country of residence. A Non-U.S. Holder who claims the benefit of an applicable income tax treaty between the United States and such holder’s country of residence generally will be required to provide a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) and satisfy applicable certification and other requirements. Special certifications and requirements may apply to a Non-U.S. Holder that is an intermediary or that owns stock through an intermediary. A Non-U.S. Holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may generally obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim with the IRS. Non-U.S. Holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

Dividends that are treated as effectively connected with a trade or business conducted by a Non-U.S. Holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the Non-U.S. Holder within the United States, are generally exempt from the 30% withholding tax if the Non-U.S. Holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income is taxed on a net income basis at the same U.S. federal income tax rates applicable to United States persons (as defined in the Code). Any U.S. effectively connected income received by a Non-U.S. Holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such Non-U.S. Holder’s country of residence.

Because constructive distributions or distributions made in Class B common stock to a Non-U.S. Holder would not give rise to any cash from which any applicable withholding tax could be satisfied, we expect that the applicable withholding agent will withhold such taxes from shares of Class B common stock or current or subsequent payments of cash to such Non-U.S. Holder.

If the amount of a distribution exceeds our current and accumulated earnings and profits, such excess will be allocated ratably among each share of our Class B common stock and will be treated as a tax-free return of capital to the extent of a Non-U.S. Holder’s adjusted tax basis in its shares of our Mandatory Convertible Preferred Stock or our Class B common stock, and thereafter will be treated as capital gain. See “—Gain on Sale or Other Taxable Disposition” below.

Gain on Sale or Other Taxable Disposition

Subject to the discussions above under “—Distributions,” and below under “—Information Reporting and Backup Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income tax on gain recognized on a sale or other taxable disposition of our Mandatory Convertible Preferred Stock or our Class B common stock unless:

S-57

Conversion of Mandatory Convertible Preferred Stock into Class B Common Stock

A Non-U.S. Holder generally will not recognize gain or loss upon the conversion of our Mandatory Convertible Preferred Stock into our Class B common stock, except that (1) cash received upon conversion in lieu of a fractional share of Class B common stock generally will be treated as a payment in a taxable exchange for such fractional share of Class B common stock and will be subject to the treatment described above under “—Gain on Sale or Other Taxable Disposition,” (2) cash or Class B common stock received in respect of accrued and unpaid dividends that have been declared should be treated in the manner described above under “—Tax Considerations Applicable to U.S. Holders—Conversion of Mandatory Convertible Preferred Stock into Class B Common Stock,” and (3) cash or Class B common stock received in respect of accrued and unpaid dividends that have not been declared or any Fundamental Change Dividend Make-Whole Amount should be treated in the manner described above under “—Tax Considerations Applicable to U.S. Holders—Conversion of Mandatory Convertible Preferred Stock into Class B Common Stock.” In the case of payments described in (2), a Non-U.S. Holder should expect a withholding agent to withhold tax from such amounts, as described above under “—Distributions.” In the case of payments described in (3), the tax treatment of such amounts is uncertain, and therefore a withholding agent may withhold 30% of such amount as described under “—Distributions.” Non-U.S. Holders should consult their tax advisors to determine the specific tax consequences to them.

Adjustments to Conversion Rate

As described above under “—Tax Considerations Applicable to U.S. Holders—Adjustments to Conversion Rate,” adjustments in the conversion rate (or failures to adjust the conversion rate) of our Mandatory Convertible Preferred Stock that result in an increase in the proportionate interest of a Non-U.S. Holder in our assets or earnings and profits could result in deemed distributions to the Non-U.S. Holder that are taxed as described under “—Distributions.” It is possible that any withholding tax on such a deemed distribution could be withheld from cash dividends, shares of our Class B common stock or sale proceeds subsequently paid or credited to such Non-U.S. Holder.

Information Reporting and Backup Withholding

Generally, distributions in respect of our Mandatory Convertible Preferred Stock or our Class B common stock to a Non-U.S. Holder and the amount of any tax withheld from such payments must be reported annually to the IRS and to the Non-U.S. Holder. Copies of these information returns may be made available by the IRS to the tax authorities of the country in which the Non-U.S. Holder is a resident under the provisions of an applicable income tax treaty. Under certain circumstances, backup withholding of U.S. federal income tax may apply to

S-58

distributions in respect of our Mandatory Convertible Preferred Stock or our Class B common stock to a Non-U.S. Holder if the Non-U.S. Holder fails to certify under penalties of perjury that it is not a United States person.

Payments of the proceeds of the sale or other disposition of our Mandatory Convertible Preferred Stock or our Class B common stock to or through a foreign office of a U.S. broker or of a foreign broker with certain specified U.S. connections will be subject to information reporting requirements, unless (i) the broker has evidence in its records that the payee is not a United States person, and the broker has no actual knowledge or reason to know to the contrary or (ii) the payee otherwise establishes an exemption; and generally will not be subject to backup withholding. Payments of the proceeds of a sale or other disposition of our Mandatory Convertible Preferred Stock or our Class B common stock to or through the U.S. office of a broker will be subject to information reporting and backup withholding, unless the payee certifies under penalties of perjury that it is not a United States person (and the payor has no actual knowledge or reason to know to the contrary) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a Non-U.S. Holder’s U.S. federal income tax liability (if any), provided that the required information is timely furnished to the IRS. Non-U.S. Holders should consult their tax advisors about the filing of a U.S. federal income tax return in order to obtain a refund.

FATCA

Holders should be aware that, under Sections 1471 through 1474 of the Code (“FATCA”), a 30% withholding tax will be imposed on certain payments (which could include dividends in respect of our Mandatory Convertible Preferred Stock or Class B common stock) to a foreign entity, whether a beneficial owner or intermediary, if such entity fails to satisfy certain disclosure and reporting rules that in general require that (i) in the case of a foreign financial entity, the entity, or a related entity, register with the IRS and identify and provide information in respect of financial accounts with such entity held (directly or indirectly) by United States persons and United States owned foreign entities, and (ii) in the case of a non-financial foreign entity, the entity identify and provide information in respect of substantial United States owners of such entity. Foreign entities that hold our Mandatory Convertible Preferred Stock or our Class B common stock generally will be subject to this tax unless they certify on an applicable IRS Form W-8 (generally, IRS Form W-8BEN-E) that they comply with, or are deemed to comply with, or are exempted from the application of, these rules.

Various requirements and exceptions are provided under FATCA and additional requirements and exceptions may be provided in subsequent guidance. Further, the United States has entered into many intergovernmental agreements (“IGAs”) with foreign governments relating to the implementation of, and information sharing under, FATCA and such IGAs may alter one or more of the FATCA information reporting rules. Holders should consult their tax advisors regarding the potential application and impact of these requirements based on their particular circumstances. Particularly, Non-U.S. Holders should consult their tax advisors regarding the possible implications of FATCA on their investment in our Mandatory Convertible Preferred Stock or our Class B common stock and the entities through which they hold our Mandatory Convertible Preferred Stock or our Class B common stock.

The preceding discussion of material U.S. federal tax considerations is for prospective investors’ information only. It is not tax advice. Prospective investors should consult their own tax advisors regarding the particular U.S. federal, state, local, and non-U.S. tax consequences of the purchasing, converting, and disposing of our Mandatory Convertible Preferred Stock or our Class B common stock, including the consequences of any proposed changes in applicable laws.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Morgan Stanley & Co. LLC and J.P. Morgan Securities LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the number of shares of Mandatory Convertible Preferred Stock indicated below:

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriters are offering the shares of Mandatory Convertible Preferred Stock subject to their acceptance of the shares of Mandatory Convertible Preferred Stock from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of Mandatory Convertible Preferred Stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of Mandatory Convertible Preferred Stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ over-allotment option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of Mandatory Convertible Preferred Stock directly to the public at the offering price listed on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of $0.975 per share under the public offering price. After the initial offering of the shares of Mandatory Convertible Preferred Stock, the offering price and other selling terms may from time to time be varied by the representatives.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 1,500,000 additional shares of Mandatory Convertible Preferred Stock from us, solely to cover over-allotments, if any, at the public offering price listed on the cover page of this prospectus

S-60

supplement, less underwriting discounts and commissions. To the extent the over-allotment option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of Mandatory Convertible Preferred Stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of shares of Mandatory Convertible Preferred Stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ over-allotment option to purchase up to 1,500,000 additional shares of Mandatory Convertible Preferred Stock.

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $659,500.

Prior to this offering, there has been no public market for the Mandatory Convertible Preferred Stock. We intend to apply to list the Mandatory Convertible Preferred Stock on The Nasdaq Global Select Market under the symbol “VIACP.” Our Class B common stock is listed for trading on The Nasdaq Global Select Market under the symbol “VIAC.”

We have agreed that we will not (and that we will ensure our affiliates (other than National Amusements, Inc.) do not) (i) offer, sell, contract to sell, announce the intention to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise), directly or indirectly, or file (or participate in the filing) with the SEC a registration statement relating to any shares of our Class B common stock or securities convertible into or exchangeable for securities of our Class B common stock, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other shares of Class B common stock or any securities convertible into, or exercisable, or exchangeable for, shares of Class B common stock, or publicly announce an intention to effect any such transaction, in each case without the prior written consent of Morgan Stanley & Co. LLC for a period of 90 days after the date of this prospectus supplement, other than (a) the shares of Mandatory Convertible Preferred Stock to be sold pursuant to this prospectus supplement or any shares of Class B common stock upon settlement thereof; (b) any shares of our Class B common stock issued upon the conversion of securities (including shares of our Class A common stock) or the exercise of warrants outstanding as of the date of this prospectus supplement; (c) our issuance of Class B common stock in the Concurrent Offering; (d) our issuance of shares of Class B common stock issuable as dividends on the Mandatory Convertible Preferred Stock; (e) our issuance of Class B common stock, options or other securities pursuant to any of our employee stock option plan, stock ownership plan or dividend reinvestment plan or any other plan in effect as of the date of this prospectus supplement; (f) the filing of a registration statement on Form S-8 with respect to any employee stock option plan, stock ownership plan, dividend reinvestment plan or any other plan described in clause (e) above; (g) our issuance of Class B common stock, options or other securities convertible into or exercisable for shares of Class B common stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of restricted stock units (including net settlement), in each case outstanding on the date of this prospectus supplement; (h) the entering into an acquisition agreement, or the public announcement of such agreement, that would provide for the issuance of Class B common stock, provided that any such issuance may not occur during the 90-day period

S-61

described in the foregoing sentence; and (i) our issuance, if any, of shares of Class B common stock issuable upon conversion of the Mandatory Convertible Preferred Stock pursuant to the certificate of designations.

Our directors, our executive officers and National Amusements, Inc., our controlling stockholder, have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons, with limited exceptions, for a period of 45 days after the date of this prospectus supplement, may not, without the prior written consent of Morgan Stanley & Co. LLC, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Class B common stock or any securities convertible into or exercisable or exchangeable for Class B common stock, or enter into any swap, hedge or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Class B common stock or any securities convertible into or exercisable or exchangeable for Class B common stock, whether in any case such transaction is to be settled by delivery of Class B common stock or such other securities, in cash, or otherwise.

In order to facilitate the offering of the Mandatory Convertible Preferred Stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Mandatory Convertible Preferred Stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Mandatory Convertible Preferred Stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of Mandatory Convertible Preferred Stock in the open market to stabilize the price of the Mandatory Convertible Preferred Stock. These activities may raise or maintain the market price of the Mandatory Convertible Preferred Stock above independent market levels or prevent or retard a decline in the market price of the Mandatory Convertible Preferred Stock. The underwriters are not required to engage in these activities and may end any of these activities at any time. Such stabilization shall be in accordance with Regulation M.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus supplement in electronic format may be made available on websites maintained by one or more underwriters participating in this offering. The representatives may agree to allocate a number of shares of Mandatory Convertible Preferred Stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, commercial banking, investment banking, corporate trust and advisory services for us for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in various other transactions with and perform services for us in the ordinary course of their business, for which they will receive customary fees and expenses.

S-62

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments. In addition, the underwriters are acting as underwriters in connection with the Concurrent Offering.

One or more of the underwriters may be restricted in its U.S. securities dealings under the United States Bank Holding Company Act and may not be U.S.-registered broker-dealer(s). All sales of securities in the U.S. will be made by or through U.S.-registered broker-dealers.

ICBC Standard Bank Plc is restricted in its U.S. securities dealings under the United States Bank Holding Company Act and may not underwrite, subscribe, agree to purchase or procure purchasers to purchase Mandatory Convertible Preferred Stock that are offered or sold in the United States. Accordingly, ICBC Standard Bank Plc shall not be obligated to, and shall not, underwrite, subscribe, agree to purchase or procure purchasers to purchase Mandatory Convertible Preferred Stock that may be offered or sold by other underwriters in the United States. ICBC Standard Bank Plc shall offer and sell the Mandatory Convertible Preferred Stock constituting part of its allotment solely outside the United States.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

Notice to Prospective Investors in the European Economic Area

This prospectus supplement has been prepared on the basis that any offer of securities in any Member State of the EEA will be made pursuant to an exemption under Regulation (EU) 2017/1129 (the “Prospectus Regulation”) from the requirement to publish a prospectus for offers of securities. Accordingly, any person making or intending to make an offer in that Member State of securities which are the subject of the offering contemplated in this prospectus supplement may only do so to legal entities which are qualified investors as defined in the Prospectus Regulation, provided that no such offer of securities shall require us or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation, in each case in relation to such offer.

S-63

Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities to any legal entity which is not a qualified investor as defined in the Prospectus Regulation. Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters, which constitute the final placement of the securities contemplated in this prospectus supplement.

The securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, or superseded, the “IDD”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell or otherwise make available any shares of Mandatory Convertible Preferred Stock to any retail investor (as defined above) in the EEA.

Each person in a Member State of the EEA who receives any communication in respect of, or who acquires any Mandatory Convertible Preferred Stock under, the offers to the public contemplated in this prospectus supplement to and with each underwriter and us that it and any person on whose behalf it acquires Mandatory Convertible Preferred Stock is: (1) a “qualified investor” within the meaning of Article 2(e) of the Prospectus Regulation; and (2) not a “retail investor” (as defined above).

In connection with the offering, the underwriters are not acting for anyone other than us and will not be responsible to anyone other than us for providing the protections afforded to their clients nor for providing advice in relation to the offering.

MiFID II product governance / Professional investors and eligible counterparties only target market

Solely for the purposes of the product governance requirements contained within: (a) MiFID II; (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the “MiFID II Product Governance Requirements”), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any “manufacturer” (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Mandatory Convertible Preferred Stock have been subject to a product approval process, which has determined that such Mandatory Convertible Preferred Stock are: (i) compatible with an end target market of investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the “Target Market Assessment”). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Mandatory Convertible Preferred Stock may decline and investors could lose all or part of their investment; the Mandatory Convertible Preferred Stock offer no guaranteed income and no capital protection; and an investment in the Mandatory Convertible Preferred Stock is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the offer. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Mandatory Convertible Preferred Stock.

Accordingly any person making or intending to make an offer in the UK of securities which are the subject of the offering contemplated in this prospectus supplement may only do so to legal entities which are qualified investors as defined in the UK Prospectus Regulation, provided that no such offer of securities shall require us or any of the underwriters to publish a prospectus pursuant to Article 3 of the UK Prospectus Regulation or section 85 of the FSMA or supplement a prospectus pursuant to Article 23 of the UK Prospectus Regulation, in each case in relation to such offer.

Neither we nor the underwriters have authorized, nor do they authorize, the making of any offer of securities through any financial intermediary, other than offers made by the underwriters, which constitute the final placement of the securities contemplated in this prospectus supplement.

The securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the UK.

DESCRIPTION OF DEBT SECURITIES

The following description of ViacomCBS’ debt securities to be issued under the Indenture (as defined below) summarizes the general terms and provisions of its debt securities to which any prospectus supplement may relate. The description set forth below and in any prospectus supplement is not complete and is subject to, and qualified in its entirety by reference to, the Indenture. ViacomCBS will describe the specific terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions summarized in this description may apply to any series of its debt securities in the prospectus supplement relating to that series. References to “ViacomCBS” in this description are references to ViacomCBS Inc. and not its consolidated subsidiaries, unless the context requires otherwise.

ViacomCBS may issue its debt securities from time to time, in one or more series under a base indenture dated as of March 27, 2020, between ViacomCBS and Deutsche Bank Trust Company Americas, as trustee, or another trustee named in a prospectus supplement. We refer to this indenture, as may be supplemented from time to time, as the “Indenture.” The trustee under the Indenture is called the “Trustee.”

The Indenture does not limit the amount of debt securities that may be issued thereunder. The Indenture provides that debt securities may be issued up to an aggregate principal amount authorized by ViacomCBS and may be payable in any currency or currency unit designated by ViacomCBS.

General

ViacomCBS may issue debt securities from time to time and offer its debt securities on terms determined by market conditions at the time of their sale. ViacomCBS may issue debt securities in one or more series with the same or various maturities and at the same or various prices including at par, at a premium, or at a discount. Any debt securities bearing no interest or interest at a rate which at the time of issuance is below market rates will be sold at a discount, which may be substantial, from their stated principal amount. ViacomCBS will describe the material United States federal income tax consequences and other special considerations applicable to any substantially discounted debt securities in a related prospectus supplement.

You should refer to the prospectus supplement for the following terms of the debt securities offered by this registration statement:

3

If ViacomCBS sells any of the debt securities for one or more foreign currencies or foreign currency units or if the principal of, premium, if any, or interest on any series of debt securities will be payable in one or more foreign currencies or foreign currency units, it will describe the restrictions, elections, any material United States federal income tax consequences, specific terms and other information with respect to the issue of debt securities and the currencies or currency units in the related prospectus supplement. Unless otherwise specified in the prospectus supplement, debt securities will be issued in U.S. dollars.

Unless specified otherwise in a prospectus supplement, the principal of, premium, if any, and interest on the debt securities will be payable, and the debt securities will be transferable, at the corporate trust office of the applicable Trustee in New York, New York. However, ViacomCBS may make payment of interest, at its option, by check mailed on or before the payment date to the address of the person entitled to the interest payment or by transfer to an account held by the payee as it appears on the registry books of the Trustee, ViacomCBS or its agents.

Unless specified otherwise in a prospectus supplement, ViacomCBS will issue the debt securities in registered form and in denominations of $2,000 and any integral multiple of $1,000. No service charge will be made for any transfer or exchange of any debt securities, but ViacomCBS may, except in specific cases not involving any transfer, require payment of a sufficient amount to cover any tax or other governmental charge payable in connection with the transfer or exchange.

ViacomCBS’ rights and the rights of its creditors, including holders of debt securities, to participate in any distribution of assets of any ViacomCBS subsidiary upon its liquidation, reorganization or otherwise is subject to the prior claims of creditors of the subsidiary, except to the extent that ViacomCBS’ claims as a creditor of the subsidiary may be recognized.

Ranking

Any senior debt securities will be senior unsecured obligations of ViacomCBS and will rank equally in right of payment with all of ViacomCBS’ other unsecured and unsubordinated indebtedness from time to time outstanding.

Any senior subordinated debt securities will be senior unsecured subordinated obligations of ViacomCBS and will be subordinated in right of payment to ViacomCBS’ Senior Indebtedness (as defined below).

Any debt securities will be effectively subordinated to any secured indebtedness of ViacomCBS to the extent of the value of the assets securing such indebtedness. The Indenture does not limit the amount of debt that ViacomCBS or its subsidiaries can incur.

In addition, ViacomCBS conducts its operations through subsidiaries, which generate a substantial portion of ViacomCBS’ operating income and cash flow. As a result, distributions or advances from ViacomCBS’

4

subsidiaries are a major source of funds necessary to meet ViacomCBS’ debt service and other obligations. Contractual provisions, laws or regulations, as well as a subsidiary’s financial condition and operating requirements, may limit the ability of ViacomCBS to obtain cash required to pay ViacomCBS’ debt service obligations, including payments on the debt securities. The debt securities (whether senior or subordinated obligations of ViacomCBS) will be structurally subordinated to all obligations of ViacomCBS’ subsidiaries including claims with respect to trade payables. This means that holders of the debt securities of ViacomCBS will have a junior position to the claims of creditors of ViacomCBS’ subsidiaries on the assets and earnings of such subsidiaries. As of December 31, 2019, ViacomCBS’ direct and indirect subsidiaries had approximately $44 million of indebtedness, including finance lease obligations.

Global Securities

ViacomCBS may issue debt securities of a series, in whole or in part, in the form of one or more global securities and will deposit them with, or on behalf of, a depositary identified in the prospectus supplement relating to that series. ViacomCBS may issue global securities in either temporary or permanent form. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may only be transferred among the depositary, its nominees and any successors.

The specific terms of the depositary arrangement relating to a series of debt securities will be described in the prospectus supplement relating to that series. It is anticipated that the following provisions will generally apply to depositary arrangements.

Upon the issuance of a global security, the depositary for the global security or its nominee will credit on its book-entry registration and transfer system the principal amounts of the individual debt securities represented by the global security to the accounts of persons that have accounts with the depositary. The accounts will be designated by the dealers, underwriters or agents with respect to the debt securities, or by ViacomCBS if the debt securities are offered and sold directly by it. Ownership of beneficial interests in a global security will be limited to persons that have accounts with the applicable depositary participants or persons that hold interests through these participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by:

So long as the depositary for a global security or its nominee is the registered owner of that global security, the depositary or the nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the Indenture. Except as provided in the applicable prospectus supplement, owners of beneficial interests in a global security will:

The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities. Those laws may limit the market for beneficial interests in a global security.

Further Issues

Not all debt securities of any one series need be issued at the same time and, unless otherwise provided, a series may be reopened without notice to or the consent of the holders for issuances of additional debt securities of such series.

5

Payment and Paying Agents

Any payments of principal, premium or interest on individual debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee as the registered owner of the global security representing the debt securities. Neither ViacomCBS, the Trustee, any paying agent, nor the security registrar for the debt securities will have any responsibility or liability for the records relating to or payments made on account of beneficial ownership interests of the global security for the debt securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

ViacomCBS expects that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium or interest in respect of a permanent global security representing any of the debt securities, will immediately credit participants’ accounts with payments in amounts proportionate to their beneficial interests in the principal amount of the global security for the debt securities as shown on the records of the depositary or its nominee. ViacomCBS also expects that payments by participants to owners of beneficial interests in the global security held through the participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name.” The payments will be the responsibility of those participants.

Merger, Consolidation or Sale of Assets

Under the terms of the Indenture, ViacomCBS generally would be permitted to consolidate or merge with or into another entity or sell or convey all or substantially all of ViacomCBS’ respective property and assets to another entity, subject to ViacomCBS meeting all of the following conditions:

ViacomCBS may merge or consolidate with, or sell all or substantially all of its assets to any of its Subsidiaries. References in this section to the sale or conveyance of “all or substantially all of its property and assets” mean property and assets contributing, in the aggregate, at least 80% of the total consolidated revenues of ViacomCBS.

In the event that ViacomCBS consolidates or merges with another entity or sells all or substantially all of its assets to another entity, the surviving entity shall be substituted for ViacomCBS under the Indenture and ViacomCBS shall be discharged from all of its obligations under the Indenture.

Limitations on Liens

ViacomCBS covenants in the Indenture that it will not create, assume or suffer to exist any Lien on any of its properties or assets, without securing the debt securities at least equally and ratably with (or prior to) the secured Indebtedness. The foregoing only applies to Liens that in the aggregate exceed 15% of ViacomCBS’ total consolidated assets as of the end of ViacomCBS’ most recent accounting period preceding the creation or assumption of any such Lien (reduced by the Attributable Debt related to any permitted sale and leaseback

6

arrangement). See “—Limitations on Sale and Leaseback Transactions” below. The restrictions do not apply to Finance Leases or Indebtedness that is secured by:

The restrictions do not apply to extensions, renewals or replacements of any of the foregoing types of Liens.

Limitations on Sale and Leaseback Transactions

ViacomCBS covenants in the Indenture that neither ViacomCBS nor any Restricted Subsidiary will enter into any arrangement with any person to lease a Principal Property (except for any arrangements that exist on the date debt securities are issued or that exist at the time any person that owns a Principal Property becomes a Restricted Subsidiary) that has been or is to be sold or transferred by ViacomCBS or the Restricted Subsidiary to the person unless:

The term “Attributable Debt,” with regard to a sale and leaseback arrangement of a Principal Property, is defined in the Indenture as an amount equal to the lesser of: (a) the fair market value of the property (as determined in good faith by the Board of Directors); or (b) the present value of the total net amount of rent payments to be made under the lease during its remaining term (including any period for which such lease has been extended and excluding any unexercised renewal or other extension options exercisable by the lessee, and excluding amounts on account of maintenance and repairs, services, taxes and similar charges and contingent rents), discounted at the rate of interest set forth or implicit in the terms of the lease (or, if not practicable to determine such rate, the

7

weighted average interest rate per annum borne by the debt securities of the applicable series then outstanding), compounded semi-annually. The calculation of the present value of the total net amount of rent payments is subject to adjustments specified in the Indenture.

The term “Principal Property” is defined in the Indenture to include any parcel of real property and related fixtures or improvements (other than telecommunications equipment, including, without limitation, satellite transponders) owned by ViacomCBS or any Restricted Subsidiary and located in the United States, the aggregate book value of which on the date of determination exceeds $1.5 billion, other than any such real property and related fixtures or improvements that are determined in good faith by the Board of Directors not to be of material importance to the total business conducted by ViacomCBS and its Subsidiaries, taken as a whole. As of the date of this prospectus, neither ViacomCBS nor any of its Subsidiaries own any Principal Property.

Defaults and Remedies

Holders of debt securities will have specified rights if an Event of Default (as defined below) occurs in respect of the debt securities of that series, as described below.

The term “Event of Default” in respect of the debt securities of a particular series means any of the following:

If an Event of Default has occurred, the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the affected series may declare the entire unpaid principal amount of (and premium, if any), and all the accrued interest on, the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. There is no action on the part of the Trustee or any holder of debt securities required for such declaration if the Event of Default is a bankruptcy, insolvency or reorganization. Holders of a majority in principal amount of the debt securities of a series may also waive certain past defaults under the Indenture on behalf of all of the holders of such series of debt securities. A declaration of acceleration of maturity with respect to a series of debt securities may be rescinded and annulled, under specified circumstances, by the holders of a majority in principal amount of the outstanding debt securities of such series.

Except in cases of default, where the Trustee has special duties, the Trustee is not required to take any action under the Indenture at the request of holders unless the holders offer the Trustee reasonable protection from costs, expenses, claims and liability satisfactory to the Trustee. If a reasonable indemnity satisfactory to the Trustee is provided, the holders of a majority in principal amount of a series of debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. The Trustee may refuse to follow those directions in certain circumstances specified in the Indenture. No delay or omission in exercising any right or remedy will be treated as a waiver of the right, remedy or Event of Default.

8

Before holders of a series of debt securities are allowed to bypass the Trustee and bring a lawsuit or other formal legal action or take other steps to enforce their rights or protect their interests relating to the debt securities of such series, the following must occur:

Holders are, however, entitled at any time to bring a lawsuit for the payment of money due on the debt securities on or after the due date.

Modification of the Indenture

The Indenture provides that ViacomCBS and the Trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for the purposes, among other things, of:

With specific exceptions, the Indenture or the rights of the holders of the debt securities may be modified by ViacomCBS and the Trustee with the consent of the holders of a majority in aggregate principal amount of the debt securities of each series affected by the modification then outstanding (all such series voting together as a single class); however, no modification may be made without the consent of the holders of each outstanding debt security affected, which would, among other things:

9

Meetings

The Indenture contains provisions for convening meetings of the holders of the debt securities of any or all series. Specific terms related to such meetings of the holders are described in the Indenture.

Defeasance and Covenant Defeasance

ViacomCBS may elect either (i) to defease and be discharged from any and all obligations with respect to a series of the debt securities (except as otherwise provided in the Indenture) (“defeasance”) or (ii) to be released from its obligations with respect to certain covenants that are described in the Indenture (“covenant defeasance”), upon the deposit with the Trustee, in trust for such purpose, of money and/or government obligations that through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient, without reinvestment, to pay the principal of, premium, if any, and interest on the debt securities of such series to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous senior payments thereon. As a condition to defeasance or covenant defeasance, ViacomCBS must deliver to the Trustee an opinion of counsel to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the Indenture.

ViacomCBS may exercise its defeasance option with respect to the debt securities of any series notwithstanding its prior exercise of its covenant defeasance option. If ViacomCBS exercises its defeasance option, payment of the debt securities of such series may not be accelerated because of an event of default. If ViacomCBS exercises its covenant defeasance option, payment of the debt securities of such series may not be accelerated by reference to any covenant from which ViacomCBS is released as described under clause (ii) of the immediately preceding paragraph. However, if acceleration were to occur for other reasons, the realizable value at the acceleration date of the money and government obligations in the defeasance trust could be less than the principal and interest then due on the debt securities of such series, in that the required deposit in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors.

10

Discharge of Obligations

ViacomCBS’ obligations under the Indenture will cease to be of further effect with respect to a series of debt securities when:

Notices

Notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the security register or in accordance with the procedures of the applicable depositary, if any.

Title

ViacomCBS, the Trustee and any agent of ViacomCBS or the Trustee may treat the registered owner of any registered debt security as the absolute owner thereof (whether or not the debt security shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

Replacement of Debt Securities

ViacomCBS will replace any mutilated debt security at the expense of the holders upon surrender to the Trustee. ViacomCBS will replace debt securities that become destroyed, lost or stolen at the expense of the holder upon delivery to the Trustee of satisfactory evidence of the destruction, loss or theft thereof. In the event of a destroyed, lost or stolen debt security, an indemnity or security satisfactory to ViacomCBS and the Trustee may be required at the expense of the holder of the debt security before a replacement debt security will be issued.

Governing Law

The Indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

In specific instances, ViacomCBS or the holders of a majority of the then outstanding principal amount of the debt securities of a series issued under the Indenture may remove the Trustee with respect to debt securities of such series and appoint a successor trustee. The Trustee may become the owner or pledgee of any of the debt securities with the same rights, subject to conflict of interest restrictions, it would have if it were not the Trustee.

11

The Trustee and any successor trustee must be eligible to act as trustee under Section 310(a)(1) of the Trust Indenture Act of 1939, as amended, and shall have a combined capital and surplus of at least $50,000,000 and be subject to examination by federal or state authority. Subject to applicable law relating to conflicts of interest, the Trustee may also serve as trustee under other indentures relating to securities issued by ViacomCBS or its affiliated companies and may engage in commercial transactions with ViacomCBS and its affiliated companies. The initial Trustee under the Indenture is Deutsche Bank Trust Company Americas.

Subordination

In addition to the provisions previously described in this prospectus and applicable to all debt securities, the following description of any senior subordinated debt securities summarizes the additional terms and provisions of such senior subordinated debt securities to which any prospectus supplement may relate. The specific terms of ViacomCBS’ senior subordinated debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions summarized below may apply to any series of senior subordinated debt securities will be described in the prospectus supplement relating to that series.

Any senior subordinated debt securities will be subordinated in right of payment to ViacomCBS’ Senior Indebtedness to the extent set forth in the applicable prospectus supplement.

The payment of the principal of, premium, if any, and interest on any senior subordinated debt securities will be subordinated in right of payment to the prior payment in full of all of ViacomCBS’ Senior Indebtedness. ViacomCBS may not make payment of principal, premium, if any, sinking funds or interest, if any, on any senior subordinated debt securities unless full payment of amounts then due for principal, premium, if any, sinking funds and interest on all Senior Indebtedness has been made or duly provided for.

For purposes of the description of any senior subordinated debt securities, the term “Senior Indebtedness” of ViacomCBS means all Indebtedness of ViacomCBS, except (a) Indebtedness that, pursuant to its terms, is subordinated in right of payment to other Indebtedness and (b) Indebtedness evidenced by an instrument that expressly provides that such Indebtedness is not Senior Indebtedness. Notwithstanding anything to the contrary in the foregoing, Senior Indebtedness will not include any liability for taxes owed or owing by ViacomCBS or any trade payables.

Certain Definitions

12

DESCRIPTION OF PREFERRED STOCK

The following description sets forth certain general terms of preferred stock that ViacomCBS may offer. The terms of any series of the preferred stock will be described in the applicable prospectus supplement relating to the preferred stock being offered. The description set forth below and in any prospectus supplement is not complete, and is subject to, and qualified in its entirety by reference to, ViacomCBS’ amended and restated certificate of incorporation, amended and restated bylaws and the certificate of designations relating to each particular series of the preferred stock, which was or will be filed with the SEC at or before the issuance of the series of preferred stock. You are urged to read our amended and restated certificate of incorporation and amended and restated bylaws in their entirety. References to “ViacomCBS” in this description are references to ViacomCBS Inc. and not its consolidated subsidiaries, unless the context requires otherwise.

Terms of the Preferred Stock

Under ViacomCBS’ amended and restated certificate of incorporation, ViacomCBS is authorized to issue up to 25,000,000 shares of preferred stock, par value $0.001 per share. The Board of Directors has the authority, without approval of the stockholders, to cause shares of preferred stock to be issued from time to time in one or more series, with the numbers of shares of each series and the designations, powers, preferences and relative, participating, optional, dividend and other special rights of the shares of each such series and the qualifications, limitations, restrictions, conditions and other characteristics thereof as fixed by the Board of Directors. As of March 27, 2020 there were no shares of ViacomCBS’ preferred stock issued and outstanding.

The applicable prospectus supplement will describe the terms of each series of preferred stock, including, where applicable, the following:

The preferred stock will be, when issued against payment, fully paid and nonassessable. Holders will have no preemptive rights to subscribe for any additional securities that ViacomCBS may issue. Unless otherwise specified in the applicable prospectus supplement, the shares of each series of preferred stock will rank equally with all other outstanding series of preferred stock issued by ViacomCBS as to payment of dividends, other than with respect to cumulation of dividends, and as to the distribution of assets upon liquidation, dissolution, or winding up of ViacomCBS. Each series of preferred stock will rank senior to the common stock and any other

14

stock of ViacomCBS that is expressly made junior to that series of preferred stock. However, the Board of Directors may not cause us to issue any preferred stock, or preferred stock that is convertible into or exchangeable for other securities, that, in the aggregate with all other outstanding shares of preferred stock, could elect a majority of the Board of Directors, unless such issuance has been approved by the holders of a majority of the outstanding shares of ViacomCBS Class A Common Stock, voting separately as a class. The ability of the Board of Directors to provide for the issuance of preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change in control of ViacomCBS or changes in our management.

ViacomCBS’ rights and the rights of holders of ViacomCBS securities, including the holders of preferred stock, to participate in the distribution of assets of any subsidiary of ViacomCBS upon its liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors and preferred stockholders, except to the extent ViacomCBS may itself be a creditor with recognized claims against the subsidiary or a holder of preferred stock of the subsidiary.

Notwithstanding anything herein to the contrary, in no event shall the terms of any preferred stock issued conflict with Article XI of the ViacomCBS amended and restated bylaws during the period ending December 4, 2021, including with respect to any rights of such preferred stock to elect directors.

Dividends and Distributions

Unless otherwise specified in the prospectus supplement, holders of shares of the preferred stock will be entitled to receive, as, if and when declared by the Board of Directors or a duly authorized committee of the Board of Directors, out of funds legally available for the payment of dividends, cash dividends at the rate set forth in, or calculated in accordance with the formula set forth in, the prospectus supplement relating to the preferred stock being offered. Dividends on the preferred stock may be cumulative or noncumulative as provided in the applicable prospectus supplement. Dividends on the cumulative preferred stock will accumulate from the date of original issue and will be payable as specified in the applicable prospectus supplement. The applicable prospectus supplement will set forth the applicable dividend period with respect to a dividend payment date. If the Board of Directors or a duly authorized committee of the Board of Directors fails to declare a dividend on any series of noncumulative preferred stock for any dividend period, ViacomCBS will have no obligation to pay a dividend for that period, whether or not dividends on that series of noncumulative preferred stock are declared for any future dividend period.

No dividends will be declared or paid or set apart for payment on the preferred stock of any series ranking, as to dividends, equally with or junior to any other series of preferred stock for any period unless dividends have been or are contemporaneously declared and paid or declared and a sum sufficient for the payment of those dividends has been set apart for:

When dividends are not paid in full upon any series of preferred stock, and any other preferred stock ranking equally as to dividends with that series of preferred stock, all dividends declared upon shares of that series of preferred stock and any other preferred stock ranking equally as to dividends will be declared pro rata so that the amount of dividends declared per share on that series of preferred stock and any other preferred stock ranking equally as to dividends will in all cases bear to each other the same ratio that accrued dividends per share on the shares of that series of preferred stock and the other preferred stock bear to each other. In the case of noncumulative preferred stock, any accrued dividends described in the immediately preceding paragraph will not include any cumulation in respect of unpaid dividends for prior dividend periods.

Except as provided in the immediately preceding paragraph or the applicable prospectus supplement, unless full dividends on all outstanding shares of any series of preferred stock have been declared and paid, in the case of a

15

series of cumulative preferred stock, for all past dividend periods, or in the case of noncumulative preferred stock, for the immediately preceding dividend period, ViacomCBS may not declare dividends or pay or set aside amounts for payment or other distribution on any of its capital stock ranking junior to or equally with that series of preferred stock as to dividends or upon liquidation, other than dividends or distributions paid in shares of, or options, warrants or rights to subscribe for or purchase shares of, the common stock of ViacomCBS or other capital stock of ViacomCBS ranking junior to that series of preferred stock as to dividends and upon liquidation. Other than in connection with the distribution or trading of any of its capital stock, ViacomCBS may not redeem, purchase or otherwise acquire any of its capital stock ranking junior to or equally with that series of preferred stock as to dividends or upon liquidation, for any consideration or any moneys paid to or made available for a sinking fund for the redemption of any shares of any of its capital stock, except by conversion or exchange for capital stock of ViacomCBS ranking junior to that series of preferred stock as to dividends and upon liquidation.

Unless otherwise specified in the applicable prospectus supplement, the amount of dividends payable for any period shorter than a full dividend period shall be computed on the basis of twelve 30-day months, a 360-day year and the actual number of days elapsed in any period of less than one month.

Liquidation Preference

Unless otherwise specified in the applicable prospectus supplement, upon any voluntary or involuntary liquidation, dissolution or winding up of ViacomCBS, the holders of the preferred stock will have preference and priority over the common stock of ViacomCBS and any other class of stock of ViacomCBS ranking junior to the preferred stock upon liquidation, dissolution or winding up, for payments out of or distributions of the assets of ViacomCBS or proceeds from any liquidation, of the amount per share set forth in the applicable prospectus supplement plus all accrued and unpaid dividends, to the date of final distribution to such holders. After any liquidating payment, the holders of preferred stock will not be entitled to any other payments.

Redemption

If specified in the prospectus supplement relating to a series of preferred stock being offered, ViacomCBS may, at its option, at any time or from time to time, redeem that series of preferred stock, in whole or in part, at the redemption prices and on the dates set forth in the applicable prospectus supplement. The Board of Directors or a duly authorized committee of the Board of Directors may fix other terms of redemption, if any, of such series including, without limitation, redemption prices payable in shares of ViacomCBS Class A Common Stock or ViacomCBS Class B Common Stock; the terms and amounts of any sinking fund for the purchase or redemption of shares of such series; and any and all other powers, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof pertaining to shares of such series permitted by law.

If less than all outstanding shares of a series of preferred stock is to be redeemed, the selection of the shares to be redeemed shall be determined by lot or pro rata as may be determined to be equitable by the Board of Directors or a duly authorized committee of the Board of Directors. From and after the redemption date, unless ViacomCBS is in default in providing for the payment of the redemption price, dividends shall cease to accrue on the shares of that series of preferred stock called for redemption and all rights of the holders shall cease, other than the right to receive the redemption price.

Voting Rights

Unless otherwise described in the applicable prospectus supplement, holders of the preferred stock will have no voting rights except as required by law.

16

Conversion or Exchange Rights

The prospectus supplement relating to a series of preferred stock that is convertible or exchangeable will state the terms on which shares of that series are convertible or exchangeable into common stock, another series of preferred stock or debt securities and the terms and conditions, including, without limitation, price and rate of exchange, of such conversion or exchange.

17

DESCRIPTION OF WARRANTS

The following description sets forth certain general terms of warrants that ViacomCBS may offer. ViacomCBS may issue warrants for the purchase of its debt securities or shares of preferred stock, Class A Common Stock or Class B Common Stock. Warrants may be issued independently or together with any debt securities or shares of preferred stock, Class A Common Stock or Class B Common Stock offered by any prospectus supplement and may be attached to or separate from such debt securities or shares of preferred stock, Class A Common Stock or Class B Common Stock. The warrants are to be issued under warrant agreements to be entered into with a bank or trust company, as warrant agent, to be named in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as an agent of ViacomCBS in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants. The description set forth below and in any prospectus supplement is not complete and is subject to, and qualified in its entirety by reference to, any warrant agreement pursuant to which warrants may be issued. References to “ViacomCBS” in this description are references to ViacomCBS Inc. and not its consolidated subsidiaries, unless the context requires otherwise.

General

If warrants are offered, the prospectus supplement will describe the terms of the warrants, including the following:

Warrants may be exchanged for new warrants of different denominations. If in registered form, the warrants may be presented for registration of transfer. The warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement. Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the various securities purchasable upon the exercise of such warrants, including the right to receive payments of principal of, any premium on, or any interest on debt securities purchasable upon the exercise or to enforce the covenants in the applicable indenture or to exercise any rights as stockholders of ViacomCBS, as described below under “—No Rights as Stockholders.” If ViacomCBS maintains the ability to reduce the exercise price of any stock warrant and the right is triggered, it will comply with federal securities laws, including Rule 13e-4 under the Exchange Act, to the extent applicable.

20

Exercise of Warrants

Each warrant will entitle the holder to purchase a principal amount of debt securities or a number of shares of preferred stock, Class A Common Stock or Class B Common Stock at the exercise price as will in each case be set forth in, or calculable from, the prospectus supplement relating to the warrant. Warrants may be exercised at the times that are set forth in the prospectus supplement relating to the warrants. After the close of business on the date on which the warrant expires, or any later date to which ViacomCBS may extend the expiration date, unexercised warrants will become void.

Subject to any restrictions and additional requirements that may be set forth in the prospectus supplement relating thereto, warrants may be exercised by delivery to the warrant agent of the certificate evidencing the warrants properly completed and duly executed and of payment as provided in the prospectus supplement of the amount required to purchase the debt securities or shares of preferred stock, Class A Common Stock or Class B Common Stock purchasable upon the exercise. The exercise price will be the price applicable on the date of payment in full, as set forth in the prospectus supplement relating to the warrants. Upon receipt of the payment and the certificate representing the warrants to be exercised, properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, ViacomCBS will, as soon as reasonably practicable, issue and deliver the debt securities or shares of preferred stock, Class A Common Stock or Class B Common Stock purchasable upon the exercise. If fewer than all of the warrants represented by a certificate are exercised, a new certificate will be issued for the remaining amount of warrants.

Additional Provisions

The exercise price payable and the number of shares of preferred stock, Class A Common Stock or Class B Common Stock purchasable upon the exercise of each stock warrant will be subject to adjustment in specific events, including the issuance of a stock dividend to holders of preferred stock, Class A Common Stock or Class B Common Stock, or a combination, subdivision or reclassification of preferred stock, Class A Common Stock or Class B Common Stock, in each case as applicable. In lieu of adjusting the number of shares of preferred stock, Class A Common Stock or Class B Common Stock purchasable upon exercise of each stock warrant, ViacomCBS may elect to adjust the number of stock warrants. No adjustment in the number of shares purchasable upon exercise of the stock warrants will be required until cumulative adjustments require an adjustment of at least 1% thereof. ViacomCBS may, at its option, reduce the exercise price at any time. No fractional shares will be issued upon exercise of stock warrants, but ViacomCBS will pay the cash value of any fractional shares otherwise issuable. In case of any consolidation, merger, or sale or conveyance of the property of ViacomCBS as an entirety or substantially as an entirety, the holder of each outstanding stock warrant will have the right upon the exercise to the kind and amount of shares of stock and other securities and property, including cash, receivable by a holder of the number of shares of preferred stock, Class A Common Stock or Class B Common Stock into which the stock warrants were exercisable immediately prior thereto.

No Rights as Stockholders

Holders of stock warrants will not be entitled, by virtue of being the holders, to vote, to consent, to receive dividends, to receive notice as stockholders with respect to any meeting of stockholders for the election of the directors or any other matter, or to exercise any rights whatsoever as its stockholders, with respect to ViacomCBS.
