Net Income (Loss) Per Share Attributable to Compass, Inc.

The Company computes net income (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 income (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.

The following table sets forth the computation of basic and diluted net income (loss) per share attributable to Compass, Inc. (in millions, except share and per share amounts):

(1)For the three and six months ended June 30, 2025, the weighted-average shares used in computing net income (loss) per share attributable to Compass, Inc., basic includes 38.5 million shares related to the CIRE Share Consideration (see Note 3 — “Acquisitions”). This amount represented the minimum number of shares to be issued in connection with the acquisition of Christie's International Real Estate.

(2)The diluted weighted-average shares used to compute net income per share attributable to Compass, Inc. for the three months ended June 30, 2025 includes an additional 13.1 million shares related to the CIRE Share Consideration. These shares represent

the maximum number of incremental shares issuable in connection with the acquisition of Christie's International Real Estate that were not already included in the basic weighted-average share count.

The Company applies the if-converted method to determine the dilutive effect of its 0.25% Convertible Senior Notes (see Note 10 — “Debt”). Under this method, after-tax interest expense associated with the Convertible Notes is added back to net income in the numerator, and the shares issuable upon assumed conversion are included in the denominator, provided the effect is dilutive.

For the three and six months ended June 30, 2026, application of the if-converted method resulted in diluted earnings per share lower than basic earnings per share. Accordingly, the 0.25% Convertible Senior Notes are reflected in the diluted earnings per share calculation presented above.

In connection with the issuance of the 0.25% Convertible Senior Notes, the Company entered into capped call transactions intended to reduce potential dilution to the Company's Class A common stock upon conversion. The capped call transactions are not reflected in diluted earnings per share because their effect would be anti-dilutive, even though they are expected to reduce actual share dilution upon conversion.

The following participating securities were excluded from the computation of diluted net income (loss) per share attributable to Compass, Inc. for the periods presented, because including them would have been anti-dilutive (on an as-converted basis):
