Loss per Share

3.Loss per Share

As of March 31, 2026, the Company has two classes of common stock outstanding, Class A and Class B-1. Loss per share is calculated and reported under the “two-class” method. The “two-class” method is an earnings allocation method under which loss per share is calculated for each class of common stock considering both distributions declared or accumulated and participation rights in undistributed earnings as if all such loss had been distributed during the period.

Basic loss per share of Class A common stock is computed by dividing net loss attributable to Class A common stockholders by the weighted average number of shares of Class A common stock outstanding during the period. Diluted loss per share of Class A common stock is computed by adjusting the net loss available to Class A common stockholders and the weighted average shares of Class A common stock outstanding to give effect to potentially dilutive securities. Shares of our Class B-1 common stock are not entitled to receive any distributions or dividends. When an LLC Interest of Fluence Energy, LLC is redeemed for cash or Class A common stock by a Founder who holds shares of our Class B-1 common stock, such Founder will be required to surrender a share of Class B-1 common stock, as the case may be, which we will cancel for no consideration. In the event of cash settlement, the Company is required to issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fully fund the cash settlement. Therefore, we did not include shares of our Class B-1 common stock in the computation of basic loss per share.

In periods in which we have a loss, diluted loss per share is equal to basic loss per share because the effect of potentially dilutive securities would be antidilutive.

The following table presents the potentially dilutive securities that were excluded from the computation of diluted loss per share:
