Stock-Based Compensation and Other Employee Benefit Plans

Stock-Based Compensation and Other Employee Benefit Plans

The Company has stock-based compensation plans, under which shares of the Company’s common stock are reserved for issuance. In May 2024, MasTec’s shareholders approved the MasTec, Inc. Amended and Restated 2013 Incentive Compensation Plan (the “2013 Incentive Plan”) and the MasTec, Inc. Amended and Restated 2011 Employee Stock Purchase Plan (the “2011 ESPP”), which amendments included the authorization to issue an additional 1,200,000 shares under the 2013 Incentive Plan and 1,000,000 shares under the 2011 ESPP. Under all stock-based compensation plans in effect as of September 30, 2024, there were approximately 4,435,000 shares available for future grants. Non-cash stock-based compensation expense under all plans totaled approximately $7.3 million and $7.2 million for the three month periods ended September 30, 2024 and 2023, respectively, and totaled approximately $24.0 million and $24.3 million for the nine month periods ended September 30, 2024 and 2023, respectively. Income tax benefits associated with stock-based compensation arrangements totaled $1.2 million and $1.1 million for the three month periods ended September 30, 2024 and 2023, respectively. For the nine month periods ended September 30, 2024 and 2023, income tax benefits totaled $4.2 million and $12.9 million, respectively, including net tax shortfalls related to the vesting of share-based payment awards totaling $0.1 million and net tax benefits totaling $8.8 million, respectively.

Restricted Shares

MasTec grants restricted stock awards and restricted stock units (together, “restricted shares”) to eligible participants, which are valued based on the closing market share price of MasTec common stock (the “market price”) on the date of grant. During the restriction period, holders of restricted stock awards are entitled to vote the shares. As of September 30, 2024, total unearned compensation related to restricted shares was

approximately $43.8 million, which amount is expected to be recognized over a weighted average period of approximately 1.8 years. The fair value of restricted shares that vested, which is based on the market price on the date of vesting, totaled approximately $0.3 million for both the three month periods ended September 30, 2024 and 2023, and totaled approximately $14.7 million and $78.3 million for the nine month periods ended September 30, 2024 and 2023, respectively.
