As of June 30, 2024, unamortized stock-based compensation related to unvested stock options, restricted stock awards (excluding the Co-Founder Grant), and RSUs was $822.1 million. The weighted-average period over which such compensation expense will be recognized if the requisite service is provided is approximately 2.8 years as of June 30, 2024.

In December 2017, the Board of Directors approved the Company's Co-Founder Grant, consisting of 10.3 million shares of Class A common stock in the form of RSAs which were granted to Drew Houston, the Company’s co-founder and Chief Executive Officer. This Co-Founder Grant has service-based, market-based, and performance-based vesting conditions. The Co-Founder Grant is excluded from Class A common stock issued and outstanding until the satisfaction of these vesting conditions. The Co-Founder Grant also provides the holder with certain stockholder rights, such as the right to vote the shares with the other holders of Class A common stock and a right to cumulative declared dividends.

The Co-Founder Grant is eligible to vest over the ten-year period following the date the Company’s shares of Class A common stock commenced trading on the Nasdaq Global Select Market in connection with the Company’s IPO. The Co-Founder Grant is comprised of nine tranches that are eligible to vest based on the achievement of stock price goals, each of which are referred to as a Stock Price Target, measured over a consecutive thirty-day trading period during the Performance Period. The Performance Period began on January 1, 2019.

During the first four years of the Performance Period, no more than 20% of the shares subject to the Co-Founder Grant would be eligible to vest in any calendar year. After the first four years, all shares are eligible to vest based on the achievement of the Stock Price Targets.

The first tranche of the Co-Founder Grant, or 2.1 million shares of Class A common stock, vested in the fourth quarter of 2021. The stock-based compensation expense for Mr. Houston's Co-Founder Grant is recognized utilizing the accelerated attribution method over the requisite service period identified as the derived service period over which the market conditions are expected to be achieved, and is not reversed if the market conditions are not satisfied. Therefore no incremental stock-based compensation was recognized upon vesting of these RSAs.

The Company recognized stock-based compensation expense related to the Co-Founder Grant of $0.7 million and $1.8 million during the three and six months ended June 30, 2024, respectively, and $2.0 and $4.2 during the three and six months ended June 30, 2023, respectively. As of June 30, 2024, unamortized stock-based compensation expense related to the Co-Founder Grant was $0.6 million.
