Dilution Report (Public Markets)

What’s new? 

Public company administrators can now run a Dilution Report to help them calculate their company’s diluted earnings per share (EPS). The Dilution Report will contain the simple and weighted average of common stock outstanding (WASO), the number of incremental shares, the average trading price for common shares, and supporting information for all calculations. This feature will simplify diluted EPS calculations and help public companies meet their diluted EPS reporting requirement for their quarterly income statements.  

How does it work?

To calculate diluted EPS, an Issuer will need the WASO and shares outstanding (new common shares issued at conversion - repurchased shares) for the reporting period in question. The Issuer will calculate its own net income, preferred dividends, and after-tax cost of interest.

After logging into their Carta accounts, public company administrators can navigate to the Financial Reporting section of their profile to generate a new Dilution Report for a desired reporting period. Dilution reports are only available for periods that begin on or after an Issuer’s IPO date.


After the report is generated, the administrator can download an Excel file which includes calculated values for simple and weighted average of common shares outstanding, the number of incremental shares, the average trading price for common shares, and supporting information. The file also includes an “Errors” tab to flag any data issues that should be resolved to produce an accurate report.

Simplify diluted earnings per share calculations to meet quarterly reporting requirements for public companies

With the Dilution Report, public company administrators can:

  • Save time and reduce the work required to calculate WASO and shares outstanding to meet public company reporting requirements;
  • Customize the diluted EPS reporting period as needed;
  • Use Carta’s calculations to verify their own calculations as a sanity check; and
  • Understand if there are any data discrepancies that need to be addressed.
