AMENDMENT NO. 8 TO SCHEDULE 13D

This Amendment No. 8 to Schedule 13D is filed jointly on behalf of Jorge Mas, Jorge Mas Holdings I, LLC (“JM Holdings I”), Jorge Mas Holdings, LLC (“JM Holdings”), Jorge Mas Irrevocable Family Trust (“JM Trust”), Jose Ramon Mas Irrevocable Family Trust (“JR Trust”), Mas Equity Partners III, LLC (“Mas Partners III”), Mas Equity Partners, LLC (“Mas Partners”), and Mas Family Foundation Inc. (“Family Foundation”) (collectively, the “Reporting Person”). This Amendment No. 8 to Schedule 13D amends and updates the statements on Schedule 13D previously filed on November 14, 2004, as amended by seven amendments thereto, the last of which was filed on January 13, 2023, with respect to the Common Stock, $.10 par value (the “Shares” or “Common Stock”) of MasTec, Inc., a Florida corporation (the “Issuer”).

ITEM 3. Source and Amount of Funds or Other Consideration.

Share ownership by each of the persons reporting on this Schedule 13D reflect transfers among certain of the reporting persons as well as grants of equity compensation to Mr. Mas since January 13, 2023, all as previously reported on Forms 4 filed by Mr. Mas.

ITEM 4. Purpose of Transaction.

The purpose of this filing to is report the entry by JM Holdings I on August 16, 2024 into an amendment (the “Second Amendment”) to the previously reported prepaid variable forward sale contract entered into by JM Holdings I with an unaffiliated party (the “2019 Prepaid Forward Contract,” and, as amended to date, the “Prepaid Forward Contract”). The Second Amendment amends the Floor Price (as defined below) and Cap Price (as defined below) for each Tranche 1 Component (as defined below), which were determined based on the volume weighted average price (the “VWAP”) of MasTec, Inc.’s common stock for a specified period ended on September 9, 2024, and appropriately adjusts the number of Shares to be delivered on the respective valuation date for each Tranche 1 Component, with such adjustment resulting in a reduction in the number of Shares pledged under the Prepaid Forward Contract to 1,176,933 Shares.

The Prepaid Forward Contract provides for the settlement of the transaction, at the option of JM Holdings I, in cash or in Shares. At settlement JM Holdings I will be obligated to deliver to the buyer, on the applicable date in August or September 2025 or 2026 for the applicable component (each, a “Valuation Date”) in the first (“Tranche 1”) or second (“Tranche 2”) tranche, as applicable, of 15 components each (“Tranche 1 Components” or “Tranche 2 Components”), at JM Holdings I’s option, up to 100% of the number of Shares pledged for such component or an equivalent amount of cash. JM Holdings I entered into the 2019 Prepaid Forward Contract to provide funds for investment in the Miami Major League Soccer franchise. For more information on the terms of the Prepaid Forward Contract, please see Item 6 below.

ITEM 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer

1,176,933 Shares owned by JM Holdings I are covered by the Prepaid Forward Contract. The Prepaid Forward Contract obligates JM Holdings I to deliver to the buyer under the Prepaid Forward Contract, on each Valuation Date, at JM Holdings I’s option, up to 100% of the number of Shares pledged for the applicable component or an equivalent amount of cash. JM Holdings I pledged an aggregate of 1,176,933 Shares the (“Pledged Shares”) to secure its obligations under the Prepaid Forward Contract, and currently retains ownership and voting rights in the Pledged Shares during the term of the pledge. The number of Shares to be potentially delivered to the buyer on each Valuation Date (or on which to base the amount of cash to be delivered to the buyer on such Valuation Date) is to be determined as follows: (a) if the VWAP of Shares on the Valuation Date for the applicable Tranche 1 Component or Tranche 2 Component (each, a “Valuation Price”) is less than or equal to $97.3535 (the “Tranche 1 Floor Price”) or $78.5147 (the “Tranche 2 Floor Price,” and each of the Tranche 1 Floor Price and Tranche 2 Floor Price, a “Floor Price”), respectively, then JM Holdings I will deliver to the buyer all of the Pledged Shares for the applicable component; (b) if such Valuation Price for the Tranche 1 Component or Tranche 2 Component is greater than the Tranche 1 Floor Price or Tranche 2 Floor Price, respectively, but less than or equal to $127.6413 (the “Tranche 1 Cap Price”) or $136.9646 (the “Tranche 2 Cap Price,” and each of the Tranche 1 Cap Price and Tranche 2 Cap Price, a “Cap Price”), respectively, then JM Holdings I will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by the quotient of the applicable Floor Price divided by such Valuation Price and (c) if such Valuation Price for the Tranche 1 Component or Tranche 2 Component exceeds the Tranche 1 Cap or Tranche 2 Cap Price, respectively, then JM Holdings I will deliver to the buyer the number of Shares equal to 100% of Pledged Shares for the applicable component multiplied by the quotient of (x) the applicable Floor Price plus such excess divided by (y) such Valuation Price. Except as set forth above, JM Holdings I retains beneficial ownership of the Pledged Shares and rights related thereto, including voting power with respect thereto.
