Stock-Based Compensation | Stock-Based Compensation We grant stock-based incentive awards to attract, motivate and retain qualified employees, non-employee directors and consultants, and to align their financial interests with those of our stockholders. We utilize stock-based compensation in the form of restricted stock units, performance restricted stock units, options to purchase Class A common stock and Employee Stock Purchase Plan ("ESPP") purchase rights. Prior to our corporate conversion in December 2014, awards were provided under the 2009 Unit Incentive Plan (“the 2009 Plan”). The 2009 Plan was amended to provide that no further awards will be issued thereunder, and our board of directors and stockholders adopted and approved our 2014 Equity Incentive Plan (“the 2014 Plan” and, together with the 2009 Plan, “the Plans”). On May 30, 2024, stockholders approved an amendment to the 2014 Plan that increased the number of shares available for grant by 3,900,000. As of September 30, 2024, 4,920,079 shares of Class A common stock were available for grant under the 2014 Plan. Stock-Based Compensation Expense Stock-based compensation expense was recorded in the following cost and expense categories consistent with the respective employee or service provider’s related cash compensation (in thousands):

Employee Stock Purchase Plan During the nine months ended September 30, 2024, 194,239 shares of common stock were purchased under the ESPP at a weighted-average price of $71.16 per share, resulting in cash proceeds of $13.8 million. Compensation expense associated with ESPP purchase rights is recognized on a straight-line basis over the vesting period. At September 30, 2024, there was approximately $1.4 million of total unrecognized compensation expense related to the ESPP, which is expected to be recognized over a weighted-average period of 0.3 years.
