We compute basic earnings per share ("Basic EPS") by dividing net income (loss) by the weighted average number of common shares outstanding during the period. We compute diluted earnings per share ("Diluted EPS") by dividing net income (loss) by the sum of the weighted average number of common shares outstanding including the dilutive effect of stock-based awards as determined under the treasury stock method and of the 2026 Senior Notes using the if-converted method, as share settlement is presumed, under GAAP. In periods when we recognize a net loss, we exclude the impact of outstanding stock-based awards and the potential share settlement impact related to the 2026 Senior Notes from the Diluted EPS calculation as their inclusion would have an antidilutive effect. Accordingly, for periods in which we report a net loss, such as for the six months ended June 30, 2024 and 2023, Diluted EPS is the same as Basic EPS since dilutive common equivalent shares are not assumed to have been issued if their effect is antidilutive.

Additionally, in periods when the 2026 Senior Notes are dilutive, interest expense, net of tax, is added back to net income (loss) (the “numerator”) to calculate Diluted EPS. The Capped Calls are excluded from the calculation of Diluted EPS, as they would be antidilutive. However, upon conversion of the 2026 Senior Notes, unless the market price of our common stock exceeds the cap price, an exercise of the Capped Calls would generally offset any dilution from the 2026 Senior Notes from the conversion price up to the cap price. As of June 30, 2024 and 2023, the market price of a share of our common stock did not exceed the $107.36 cap price.

Below is a reconciliation of the weighted average number of shares of common stock outstanding used in calculating Diluted EPS for the periods presented:

Potential common shares, consisting of outstanding stock options, RSUs, and those issuable under the 2026 Senior Notes, totaling approximately 13.5 million shares and 22.1 million shares for the three and six months ended June 30, 2024, respectively, and approximately 16.1 million shares and 22.4 million shares for the three and six months ended June 30, 2023, respectively, have been excluded from the Diluted EPS calculation because their effect would have been antidilutive. In addition, potential common shares from certain performance-based awards of approximately 1.5 million shares for both the three and six months ended June 30, 2024, respectively, and approximately 1.1 million shares for both the three and six months ended June 30, 2023, respectively, for which all

targets required to trigger vesting had not been achieved, were also excluded from the calculation of weighted average shares used to compute Diluted EPS.

The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. In addition, our non-vested RSUs are entitled to dividend equivalents, which are payable to the holder subject to, and only upon vesting of, the underlying awards and are therefore forfeitable. Given such dividend equivalents are forfeitable, we do not consider them to be participating securities and, consequently, they are not subject to the two‑class method of determining earnings per share.
