Policies and Practices Related to the Timing of Equity Grants

We generally grant annual equity-based awards, including stock options, to our executive officers in January of each year, in connection with our annual compensation review process, although the exact timing may change from year to year. The Compensation Committee may also grant, or delegate the Chief Executive Officer to grant to our non-executive employees, equity awards, including stock options, at different times of the year for new hires and in connection with promotions. None of the Compensation Committee, our Board of Directors, or the Chief Executive Officer grants equity awards in anticipation of the release of material non-public information andwe have not timed the disclosure of material non-public informationfor the purpose of affecting the value of executive compensation.

The following table contains information required by Item 402(x)(2) of Regulation S-K about a stock option granted to Mr. Humer on April 16, 2024, the same day that we filed a Form 8-K disclosing Mr. Humer’s appointment as our Chief Financial Officer and the material terms of Mr. Humer’s letter agreement with us. During 2024, the Company did not grant any other stock options to any named executive officer during any period beginning four business days before and ending one business day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company current report on Form 8-K (other than a current report on Form 8-K disclosing a material new option award grant under Item 5.02(e) of that form) that disclosed any material non-public information.

Employee and Retirement Benefits

We currently provide broad-based health and welfare benefits, and certain commuter benefits, that are available to our full-time employees, including our named executive officers, including health, life, disability, vision and dental insurance. In addition, we maintain a 401(k) retirement plan for our full-time employees. The 401(k) plan permits us to make discretionary employer contributions. In 2024, we made employer contributions to the 401(k) plan of up to $3,000 per employee, including for our named executive officers. Other than the 401(k) plan, we do not provide any qualified or non-qualified retirement or deferred compensation benefits to our employees, including our named executive officers.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and persons who own more than 10% of Foghorn’s common stock to file reports of ownership and changes in ownership with the SEC. As a matter of practice, the Company assists its executive officers and directors in preparing initial reports of ownership and reports of changes in ownership and files those reports on their behalf. Based on our review of such forms, as well as information provided by the reporting persons, we believe that each of our executive officers, directors and beneficial owners of more than 10% of its common stock complied with the reporting requirements of Section 16(a) during the year ended December 31, 2024.
