How to Find Outstanding Warrants: SEC Filings, Data Sources, and Tools
Updated April 2026 DilutionWatch Research

Finding comprehensive warrant data requires checking multiple SEC filings because warrant information is not centralized in any single location. According to DilutionWatch data covering 7,300+ stocks, the average company with warrants has 2-3 different warrant series with varying exercise prices, expiration dates, and terms, making thorough research essential.

The primary source for warrant data is the equity footnotes in quarterly (10-Q) and annual (10-K) SEC filings. Look for footnotes titled 'Stockholders' Equity,' 'Warrants,' or 'Stock-Based Compensation.' These footnotes typically include a warrant activity table showing beginning balance, warrants issued, warrants exercised, warrants expired, and ending balance for each reporting period, along with weighted average exercise prices.

The initial warrant terms are found in the offering documents — typically prospectus supplements (Form 424B) for public offerings or 8-K filings for private placements. These documents describe the exercise price, expiration date, anti-dilution provisions, cashless exercise rights, and any other special terms. Understanding these terms is critical for modeling the dilution impact of future exercises.

Additional warrant data can be found in proxy statements (Form DEF 14A) which may reference warrants in executive compensation tables, in S-1 and S-3 registration statements which list outstanding securities, and in Form 4 filings when insiders exercise warrants. Each of these filings provides a different perspective on the company's warrant position.

DilutionWatch consolidates warrant data from all of these filing sources into a single, comprehensive warrant table for each company. The table includes exercise prices, quantities, expiration dates, exercise provisions (cash vs. cashless), and anti-dilution features. This consolidated view, updated with each new filing, eliminates the need for investors to manually search and reconcile data across multiple SEC filings.

Frequently Asked Questions

Where are warrants disclosed in SEC filings?

Warrants are primarily disclosed in the equity footnotes of 10-Q and 10-K filings. Initial terms are in prospectus supplements (424B) or 8-K filings. Exercise activity by insiders appears in Form 4 filings. DilutionWatch consolidates all sources automatically.

Do all warrants appear in the share count?

No. Outstanding warrants are not included in the basic shares outstanding count on the 10-Q cover page. They appear in the diluted share count only if they are in-the-money. Pre-funded warrants with nominal exercise prices should always be counted as shares.

How often is warrant data updated in SEC filings?

Warrant tables are updated quarterly in 10-Q and 10-K filings. Individual warrant exercises may be reported more frequently through Form 4 filings (for insiders) or 8-K filings (for significant exercises). DilutionWatch tracks all updates in real time.
