STOCKHOLDERS’ EQUITY

12. STOCKHOLDERS’ EQUITY

Preferred Stock

The Company has 10 million shares of undesignated preferred stock authorized but not issued with rights and preferences determined by the Company’s Board of Directors (the “Board”) at the time of issuance of such shares. As of March 31, 2026 and December 31, 2025, there were no shares of preferred stock issued and outstanding.

Common Stock

The Company has two classes of authorized common stock, Class A common stock and Class B common stock. Holders of Class A common stock are entitled to one vote for each share of Class A common stock held on all matters submitted to a vote of stockholders and holders of Class B common stock are entitled to ten votes for each share of Class B common stock held on all matters submitted to a vote of stockholders. Except with respect to voting, the rights of the holders of Class A and Class B common stock are identical. Shares of Class B common stock are voluntarily convertible into shares of Class A common stock at the option of the holder and are generally automatically converted into shares of the Company’s Class A common stock upon sale or transfer. Shares issued in connection with exercises of stock options or vesting of restricted stock units are generally automatically converted into shares of the Company’s Class A common stock.

Stock Repurchase Program

In August 2025, the Company began repurchasing shares of the Company’s Class A common stock under a stock repurchase program approved by the Board pursuant to which the Company is authorized to repurchase up to $400 million of the Company’s Class A common stock through December 31, 2026. The program does not obligate the Company to acquire any amount of Class A common stock, and the timing and total amount of share repurchases will depend on general market conditions, the trading price of the Company’s Class A common stock, corporate and regulatory requirements, the availability of funds, other investment opportunities, and other considerations. Repurchases may be executed through open market transactions at prevailing market prices, including pursuant to trading plans that comply with the requirements of Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, or through other means.

The following table summarizes the share repurchase activity under the Company’s stock repurchase program during the three months ended March 31, 2026 (in thousands, except share and per share data):

Equity Incentive Plans

The Company currently grants equity awards under the Amended and Restated 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan became effective September 2017 in connection with the Company’s initial public offering (“IPO”). The 2017 Plan provides for the grant of incentive stock options to the Company’s employees and for the grant of non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards, and other forms of equity compensation to the Company’s employees, directors and consultants. The outstanding equity relates to the 2017 Plan and the 2008 Equity Incentive Plan (“2008 Plan”), a pre-IPO plan. No additional equity grants have been made pursuant to the 2008 Plan subsequent to the IPO.

The equity awards granted under the 2017 Plan vest subject to continuous service. Stock options granted under the 2017 Plan generally are granted at a price per share equivalent to the fair market value on the date of grant. Recipients of incentive stock option grants who possess more than 10% of the combined voting power of the Company are subject to certain limitations, and incentive stock options granted to such recipients are at a price no less than 110% of the fair market value at the date of grant.
