Net Loss Per Share Attributable to Compass, Inc.
The Company computes net loss per share under the two-class method required for multiple classes of common stock and participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock, Class B common stock and Class C common stock are substantially identical, other than voting rights. Accordingly, the net loss per share attributable to Compass, Inc. will be the same for Class A common stock, Class B common stock and Class C common stock on an individual or combined basis.

In January 2026, the number of shares issuable to the Non-Accelerated Sellers was finalized and determined to be 10.5 million shares. See Note 3 – “Acquisitions” for more information regarding the CIRE Merger.
The following participating securities were excluded from the computation of diluted net loss per share attributable to Compass, Inc. for the periods presented because including them would have been anti-dilutive (on an as-converted basis):

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.
