Share-Based Payment Arrangement [Abstract] |
Stock-Based Compensation | Stock-Based Compensation Refer to our Annual Report on Form 10-K for the fiscal year ended September 30, 2025 for a full description of our existing stock-based compensation plans. Restricted Stock Units We issue restricted stock units (RSUs) to certain officers and key employees of the Company. The fair value of the RSUs is based on the price of our common stock as reported on the NASDAQ Global Market during a specified period prior to the grant dates. Typically, these grants vest over a three-year period from the date of issuance and are a blend of time-based and performance-based shares. The portion of the grant that is time-based typically vests over a three-year period on each anniversary of the grant date, based on continued employment. The performance-based shares vest based on the three-year revenue growth, earnings and safety performance of the Company following the grant date. At March 31, 2026, there were 166,431 RSUs outstanding, as adjusted for the Stock Split. The RSUs do not have voting rights but do receive dividend equivalents upon vesting, which are accrued quarterly. Additionally, the shares of common stock underlying the RSUs are not considered issued and outstanding until vested and common stock is issued. Total RSU activity (number of shares), as adjusted for the Stock Split, for the six months ended March 31, 2026 is summarized below:
| Number of Restricted Stock Units |  | Weighted Average Grant Value Per Share
Outstanding at September 30, 2025 | 350,658 |  |  | $ | 21.60 |
Granted | 59,085 |  |  | 95.75 |
Vested | (243,312) |  |  | 12.74 |
Forfeited/canceled | — |  |  | — |
Outstanding at March 31, 2026 | 166,431 |  |  | $ | 55.84 |
During the six months ended March 31, 2026 and 2025, we recorded compensation expense of $2.5 million and $2.2 million, respectively, related to the RSUs. Restricted Stock Each year, every non-employee director receives restricted shares of the Company’s common stock with a grant-date value of $0.1 million. The number of granted shares is calculated by dividing the $0.1 million by the average of high and low prices of our common stock on the grant date. The shares shall vest on the earlier of the grant anniversary date or the date of the next annual meeting of stockholders, whichever occurs first. In February 2026, 4,200 shares of restricted stock were issued to our non-employee directors at a price of $184.83 per share, as adjusted for the Stock Split. During both the six months ended March 31, 2026 and 2025, we recorded compensation expense of $0.4 million related to restricted stock.
