Stock Repurchase Program
We have a Board-approved stock repurchase program authorizing repurchases of up to $150.0 million of our common stock. This program does not have an expiration date; however, we will periodically review the authorization to assess its continued appropriateness in light of our capital allocation priorities and market conditions. The number of shares repurchased and the timing of repurchases depend on the level of our cash balances, general business and market conditions and other factors, including alternative investment opportunities.
During the three months ended September 2025, we repurchased $7.2 million of our common stock and $142.8 million remains available for future stock repurchases under the stock repurchase program.

The unrecognized share-based compensation cost of our outstanding MSUs was approximately $14.8 million as of September 2025, which will be recognized over a weighted average period of approximately 2.14 years.

Balance as of September 2025285,345$76.4 
We value PSUs using the aggregate intrinsic value on the date of grant adjusted for estimated performance achievement during the performance period and amortize the compensation expense over the three-year service period on a ratable basis. The amount of stock-based compensation expense recognized in any period related to PSUs can vary based on the achievement or anticipated achievement of the performance conditions. If the performance conditions are not met, or not expected to be met, no compensation cost would be recognized on the underlying PSUs, and any previously recognized compensation expense related to those PSUs would be reversed. The unrecognized share-based compensation cost of our outstanding PSUs was approximately $13.6 million as of September 2025, which will be recognized over a weighted average period of approximately 1.39 years.
