See Note 14 — Management Incentive Plans for a discussion of the Company's management incentive plans for restricted stock units (“RSUs”) granted, vested, forfeited and remaining unvested.
Share Repurchase Program
In December 2025, the Company announced that its Board of Directors authorized a share repurchase program (the “Share Repurchase Program”), pursuant to which the Company may, from time to time, purchase up to $50.0 million of shares of its common stock through December 15, 2027. Share repurchases may be executed through various means, including, without limitation, open market transactions, privately negotiated transactions or by other means in accordance with federal securities laws. Repurchases may also be made under Rule 10b5-1 plans. The Share Repurchase Program does not obligate the Company to acquire any particular amount of common stock, and the program may be suspended or terminated by the Company at any time at its discretion without prior notice. As of March 31, 2026, the Company has not repurchased any common stock under its Share Repurchase Program.
Employee Stock Purchase Plan
Upon approval of the Company's stockholders on May 30, 2019, the Company adopted the Limbach Holdings, Inc. 2019 Employee Stock Purchase Plan (the “ESPP”). On January 1, 2020, the ESPP went into effect. The ESPP enables eligible employees, as defined by the ESPP, the right to purchase the Company's common stock through payroll deductions during consecutive subscription periods at a purchase price of 85% of the fair market value of a share of the Company's common stock at the end of each offering period. Annual purchases by participants are limited to the number of whole shares that can be purchased by an amount equal to ten percent of the participant's compensation or $5,000, whichever is less. Each offering period of the ESPP lasts six months, commencing on January 1st and July 1st of each year. The amounts collected from participants during a subscription period are used on the exercise date to purchase full shares of common stock. Participants may withdraw from an offering before the exercise date and obtain a refund of amounts withheld through payroll deductions. Compensation cost, representing the 15% discount applied to the fair market value of common stock, is recognized on a straight-line basis over the six-month vesting period during which employees perform related services. Under the ESPP, 500,000 shares are authorized to be issued. In January 2026, the Company issued 3,305 shares of its common stock to participants in the ESPP who contributed to the plan during the offering period ending December 31, 2025. In January 2025, the Company issued a total of 2,321 shares of its common stock to participants in the ESPP who contributed to the plan during the offering period ending December 31, 2024. As of March 31, 2026, 375,065 shares remain available for future issuance under the ESPP.
