(4)   Earnings Attributable to Liberty Media Corporation Stockholders Per Common Share

Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding (“WASO”) for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented, including any necessary adjustments to earnings (loss) attributable to shareholders.

In August 2020, the Financial Accounting Standards Board issued Accounting Standards Update 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) which removes the separation models for convertible debt with cash conversion or beneficial conversion features and also requires the application of the if-converted method for calculating diluted earnings per share as the treasury stock method is no longer permitted for convertible instruments. The Company adopted ASU 2020-06 as of January 1, 2022 using the modified retrospective approach, which does not require retrospective adjustment of prior period EPS, and recorded an immaterial cumulative effect adjustment to retained earnings upon adoption. The adoption of ASU 2020-06 decreased current period diluted earnings attributable to Liberty SiriusXM stockholders per common share by $0.04 per share.

Excluded from diluted EPS for the three months ended March 31, 2022 and 2021 are approximately 20 million and 22 million potentially dilutive shares of Series A and Series C Liberty SiriusXM common stock, respectively, 14 million and 3 million potentially dilutive shares of Series A and Series C Liberty Braves common stock, respectively, and 10

million and 7 million potentially dilutive shares of Series A and Series C Liberty Formula One common stock, respectively, primarily due to warrants issued in connection with the Bond Hedge Transaction (as defined in note 8) and shares of Series A Liberty Braves common stock and Series A Liberty Formula One common stock underlying the intergroup interests, because their inclusion would be antidilutive. The warrant transactions (as described in note 8) may have a dilutive effect with respect to the shares comprising the basket of Liberty’s tracking stocks as specified in the indenture, as amended, related to the Convertible Notes (the “Securities Basket”) underlying the warrants to the extent that the settlement price exceeds the strike price of the warrants, and the warrants are settled in shares comprising such Securities Basket. The warrants and any potential future settlement are attributed to the Liberty SiriusXM Group.

The intergroup interests are quasi-equity interests which are not represented by outstanding shares of common stock; rather, the Formula One Group and the Liberty SiriusXM Group have attributed values in the Braves Group which are generally stated in terms of a number of shares of stock issuable to the Formula One Group and the Liberty SiriusXM Group with respect to their interests in the Braves Group. Each reporting period, the notional shares representing the intergroup interests are marked to fair value. As the notional shares underlying the intergroup interests are not represented by outstanding shares of common stock, such shares have not been officially designated Series A, B or C Liberty Braves common stock. However, Liberty has assumed that the notional shares (if and when issued) related to the Formula One Group interest in the Braves Group would be comprised of Series C Liberty Braves common stock in order to not dilute voting percentages and the notional shares (if and when issued) related to the Liberty SiriusXM Group interest in the Braves Group would be comprised of Series A Liberty Braves common stock since Series A Liberty Braves common stock underlie the Convertible Notes. Therefore, the market prices of Series C Liberty Braves and Series A Liberty Braves common stock are used for the quarterly mark-to-market adjustment for the intergroup interests held by Formula One Group and Liberty SiriusXM Group, respectively, through the unaudited attributed condensed consolidated statements of operations. The notional shares representing the intergroup interests have no impact on the basic WASO. However, if dilutive, the notional shares representing the intergroup interests are included in the diluted WASO as if the shares had been issued and outstanding during the period. For periods in which share settlement of the intergroup interests are dilutive, an adjustment is also made to the numerator in the diluted earnings per share calculation for the unrealized gain or loss incurred from marking the intergroup interests to fair value during the period. Additionally, a hypothetical mark to market adjustment on the shares of Series A Liberty Braves common stock included in the Securities Basket underlying the warrants is included in the numerator adjustment in periods in which cash settlement of the warrants would be more dilutive than share settlement.
