REVENUE BY TYPE â–ª Advertising revenue grew 1% year-over-year, reflecting an improved advertising marketplace, partially offset by lower linear impressions, lower political advertising, and the absence of CNET Media Group (“CMG”) as a result of its sale in the fourth quarter of 2020. â–ª Affiliate revenue increased 2% year-over-year, reflecting higher reverse compensation and expanded distribution. â–ª Streaming revenue rose 62% year-over-year: – Streaming advertising revenue grew 48% year-over-year, driven by growth in advertising on Pluto TV and Paramount+. – Streaming subscription revenue grew 79% year-over-year, reflecting strong subscriber growth from the company’s subscription services. â–ª Theatrical revenue reflects the releases of Paw Patrol: The Movie, Snake Eyes: G.I. Joe Origins, and the second quarter release of A Quiet Place Part II, while the prior-year period was impacted by the closure or reduced capacity of movie theaters in response to COVID-19. â–ª Licensing and other revenue, which includes fees from the licensing of our internally produced television and film programming across third party platforms, as well as fees generated from home entertainment, consumer products, and live events, increased 18% year-over-year. VIACOMCBS Q3 2021 EARNINGS OVERVIEW OF Q3 REVENUE GLOBAL STREAMING HIGHLIGHTS â–ª Global streaming subscribers rose to nearly 47M, adding 4.3M subscribers in the quarter. – Subscriber additions in the quarter were led by Paramount+. â–ª Domestically, Paramount+ saw strong subscriber sign-ups and engagement from a variety of content, including A Quiet Place Part II, Paw Patrol: The Movie, as well as the start of the NFL season. â–ª Internationally, Paramount+ launches to date have had strong momentum, led by progress in Latin America, Brazil, Australia and Canada. – SHOWTIME OTT benefited from originals, including Billions, American Rust and The Chi. – Announced the signing of SkyShowtime, a joint venture with Comcast that will include premium and original content from both companies. â–ª SkyShowtime will reach more than 20 European territories encompassing 90 million homes. â–ª Pluto TV revenue grew 99% year-over-year, as MAUs increased to over 54M in the quarter, helped by international growth. $ IN MILLIONS Three Months Ended September 30 Nine Months Ended September 30 2021 2020 $ B/(W) % 2021 2020 $ B/(W) % Advertising* $ 1,855 $ 1,828 $ 27 1 % $ 6,633 $ 5,733 $ 900 16 % Affiliate* 2,102 2,059 43 2 6,284 5,956 328 6 Streaming 1,079 666 413 62 2,878 1,673 1,205 72 â–ª Advertising 531 360 171 48 1,461 873 588 67 â–ª Subscription 548 306 242 79 1,417 800 617 77 Theatrical 67 6 61 n/m 202 176 26 15 Licensing and other 1,507 1,278 229 18 4,589 4,873 (284) (6) Total Revenue $ 6,610 $ 5,837 $ 773 13 % $ 20,586 $ 18,411 $ 2,175 12 % *Excludes streaming revenue n/m = not meaningful 2

REPORTING SEGMENTS TV ENTERTAINMENT â–ª In Q3, CBS was the most-watched network in Daytime and Late Night. Hits like The Late Show With Stephen Colbert and Big Brother were leaders in their respective categories among key demos. â–ª Revenue grew 24% year-over-year, primarily driven by higher licensing, streaming, and affiliate revenue, partially offset by lower advertising revenue. – Advertising revenue decreased 2% year-over-year, primarily reflecting an unfavorable comparison to the prior-year revenue benefit from political advertising and the absence of CMG, partially offset by an improved advertising market in 2021. – Affiliate revenue grew 4% year-over-year, driven by growth in reverse compensation. – Streaming revenue rose 81% year-over-year, reflecting subscriber and advertising growth at Paramount+. – Licensing and other revenue increased 79% year-over-year, driven by the timing of program availability primarily due to COVID-19 production shutdowns in the prior-year, and a higher volume of domestic licensing. â–ª Adjusted OIBDA decreased 21% year-over-year, reflecting the company’s increased investment in Paramount+.

In Q3, ViacomCBS had the most programs among the top 25 original cable series among P18-49, P18-34 and K2-11, more than any other cable family, including the top two Kids programs with Paw Patrol and The Patrick Star Show. Revenue increased 13% year-over-year, reflecting growth across all revenue streams. – Advertising revenue increased 6% year-over-year, largely driven by an improved advertising marketplace, partially offset by lower linear impressions. – Affiliate revenue grew 1% year-over-year, reflecting expanded vMVPD distribution and rate increases, partially offset by subscriber declines. – Streaming revenue increased 53% year-over-year, largely fueled by advertising revenue growth from Pluto TV, as well as growth in subscribers for subscription streaming services. – Licensing and other revenue increased 23% year-over-year, primarily driven by the licensing of programming to Paramount+. Adjusted OIBDA increased 5% year-over-year, reflecting the abovementioned revenue growth, partially offset by an increased investment in streaming services and a higher level of original programming.

Revenue declined 2% year-over-year, driven by lower licensing revenues, partially offset by the benefit of current quarter theatrical releases. – Theatrical includes revenues from the third quarter releases of Paw Patrol: The Movie, Snake Eyes: G.I. Joe Origins, and the second quarter release of A Quiet Place Part II, while the prior-year period was impacted by the closure or reduced capacity of movie theaters in response to COVID-19. – Licensing and other revenue decreased 12% year-over-year due to lower volume of programming produced for third parties. Adjusted OIBDA declined $16 million year-over-year, reflecting lower profits from current year releases as a result of higher distribution costs, as well as distribution costs associated with anticipated releases.

SUPPLEMENTAL DISCLOSURES REGARDING NON-GAAP FINANCIAL MEASURES (Unaudited; in millions, except per share amounts) Results for the three and nine months ended September 30, 2021 and 2020 included certain items identified as affecting comparability. Adjusted operating income before depreciation and amortization (“Adjusted OIBDA”), adjusted earnings from continuing operations before income taxes, adjusted provision for income taxes, adjusted net earnings from continuing operations attributable to ViacomCBS, and adjusted diluted EPS from continuing operations (together, the “adjusted measures”) exclude the impact of these items and are measures of performance not calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We use these measures to, among other things, evaluate our operating performance. These measures are among the primary measures used by management for planning and forecasting of future periods, and they are important indicators of our operational strength and business performance. In addition, we use Adjusted OIBDA to, among other things, value prospective acquisitions. We believe these measures are relevant and useful for investors because they allow investors to view performance in a manner similar to the method used by our management; provide a clearer perspective on our underlying performance; and make it easier for investors, analysts and peers to compare our operating performance to other companies in our industry and to compare our year-over-year results. Because the adjusted measures are measures of performance not calculated in accordance with GAAP, they should not be considered in isolation of, or as a substitute for, operating income, earnings from continuing operations before income taxes, provision/benefit for income taxes, net earnings from continuing operations attributable to ViacomCBS or diluted EPS from continuing operations, as applicable, as indicators of operating performance. These measures, as we calculate them, may not be comparable to similarly titled measures employed by other companies. The following tables reconcile the adjusted measures to their most directly comparable financial measures in accordance with GAAP. Three Months Ended Nine Months Ended September 30, September 30, 2021 2020 2021 2020 Operating income (GAAP) $ 879 $ 903 $ 3,633 $ 3,056 Depreciation and amortization (a) 95 97 289 331 Restructuring and other corporate matters (b) 46 52 81 441 Programming charges (b) — — — 121 Net gain on sales (b) — — (116) — Adjusted OIBDA (Non-GAAP) $ 1,020 $ 1,052 $ 3,887 $ 3,949 (a) The nine months ended September 30, 2020 include an impairment charge for FCC licenses of $25 million and accelerated depreciation of $12 million for technology that was abandoned in connection with synergy plans related to the merger of Viacom Inc. with and into CBS Corporation (the “Merger”).
