16. Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to Cardinal Infrastructure Group Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted earnings per share is computed by adjusting the net income available to Cardinal Infrastructure Group Inc. and the weighted average shares outstanding to give effect to potentially dilutive securities. Shares of Class B common stock are not entitled to receive any distributions or dividends and are therefore excluded from this presentation since they are not participating securities.

As a result of the acquisition, all continuing equity holders were exchanged for Class B non-participating securities. All earnings prior to December 10, 2025, the date of the IPO, were entirely allocable to the non-controlling interests and LLC owners, as a result, earnings per share information is not applicable for reporting periods prior to this date. Consequently, only earnings per share for net income for periods subsequent to December 9, 2025 are presented.

Basic and diluted earnings per share of common stock have been computed as follows:

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.
