Pulmatrix, Inc. Earnings Per Share Disclosure
Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted loss per share is calculated by dividing net loss by the weighted-average number common shares outstanding during the period, after taking into consideration any potentially dilutive effects from outstanding stock options or warrants.
Basic and diluted net loss per share were the same for the years ended December 31, 2025, and 2024, as the effect of potentially dilutive securities would have been anti-dilutive. The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding, because such securities had an anti-dilutive impact:

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.
