Net Income (Loss) per Share Attributable to Common Stockholders
Prior to the IPO, the rights, including the liquidation and dividend rights, of the holders of voting and non-voting common stock were identical, except with respect to voting. As the liquidation and dividend rights were identical, the undistributed earnings were allocated on a proportionate basis and the resulting net income (loss) per share attributable to common stockholders were, therefore, the same for both voting and non-voting common stock on an individual or combined basis.

Immediately prior to the completion of the IPO, all outstanding shares of the Company’s non-voting common stock were converted into shares of voting common stock, all of which were subsequently reclassified into common stock. The shares issued in the IPO and the shares of common stock issued upon conversion of the then-outstanding shares of
redeemable convertible preferred stock in connection with the IPO, as well as vested RSUs, are included in the table below weighted for the period outstanding during the year ended December 31, 2023.

The computation of basic and diluted net income (loss) per share attributable to common stockholders was 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.
