**Timing of Equity Awards Our insider trading policy provides that equity awards granted under our equity compensation plans must generally be granted (a) during open trading windows, and (b) more than four business days before, and more than one business day after, our release of earnings for the most recently completed fiscal period or filing with the SEC. Consistent with our insider trading policy, we time the grant of our annual equity awards such that they are typically approved in January to be granted in March. These grants therefore do not become effective until at least one business day after the release of earnings for the prior fiscal year. We also grant equity awards throughout the year for various reasons, including recruitment of new hires, promotions, and retention or recognition. In each case, we maintain a practice of timing equity grants after earnings releases, which is designed to avoid MNPI influencing the value of the compensation. 401(k) Plan We have a tax-qualifiedretirement plan that provides eligible employees with an opportunity to save for retirement on a tax-advantagedbasis. All participants’ interests in their contributions are 100% vested when contributed. We match participant contributions up to $3,000 annually. The retirement plan is intended to qualify under Sections 401(a) and 501(a) of the Internal Revenue Code. Perquisites and Other Benefits As a general practice, we do not provide perquisites or personal benefits for our executive officers. We have historically provided limited perquisites to our named executive officers in special circumstances to allow them to better perform their duties. However, no unique perquisites were provided to our named executive officers in 2024. Health and Welfare Plans All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including medical and dental benefits, short-term and
