Adagio Medical Holdings, Inc. Earnings Per Share Disclosure
Note 15 – Loss Per Share (“LPS”)
Predecessor
Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss per common share excludes the potential impact of the Company’s convertible preferred stock, common stock warrants, and common stock options because the Company’s net losses would cause such shares to be anti-dilutive. Therefore, as the Company recorded net losses in the periods presented, basic and diluted net loss per common share are the same.

Successor
After the Business Combination, the Successor calculated basic LPS and diluted LPS to common stockholders in conformity with the two-class method required for companies with participating securities. The Company considered (i) the Convertible Securities Notes and (ii) the earnout shares subject to vesting conditions to be participating securities as they participate in any distributions declared by the Company. The Company’s Base Warrants and Convert Warrants are considered as non-participating securities, as the holders are not entitled to any shareholder right prior to the exercise of the Base Warrants and the Convert Warrants. As of the reporting date, none of the Base Warrants or the Convert Warrants were exercised to receive the Company’s common stock.
Under the two-class method, undistributed earnings allocated to these participating securities were subtracted from net income in determining net income attributable to common stockholders. In periods of net loss, losses are allocated to the participating security only if the security has not only the right to participate in earnings, but also a contractual obligation to share in the Company’s losses. As the Company incurred a net loss for the period from July 31, 2024 to December 31, 2024 (Successor), the Convertible Securities Notes were not considered participating securities, and were excluded from the two-class method LPS calculation for those periods.
Further, Basic LPS under the two-class method includes the impact of the Company’s PIPE Pre-funded Warrants as the PIPE Pre-funded Warrants are exercisable for only $0.01 per share (i.e., de minimis cash consideration) without an expiration date and not subject to exercise contingencies.
The Company discloses the Diluted LPS under the if-converted method as such diluted LPS is lower than the diluted LPS calculated under the two-class method. The Earn-out shares subject to vesting conditions are not considered in the denominator for the calculation of diluted LPS as the vesting conditions for the Earn-out shares were not met during the successor reporting period.

About Earnings Per Share Disclosures
The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.
Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
