        <footnote id="F1">As previously reported, the reporting person is party to a prepaid variable forward sale contract (as amended to date, the &quot;Forward Sale Contract&quot;) with an unaffiliated third party buyer. The reporting person pledged an aggregate of 364,850 shares (the &quot;2024 Pledged Shares&quot;) of MasTec, Inc. common stock to secure his obligations under the Forward Sale Contract, and retained ownership and voting rights in the 2024 Pledged Shares during the term of the pledge.</footnote>
        <footnote id="F2">On August 18, 2025, the reporting person and the buyer entered into a third amendment to the Forward Sale Contract (as so further amended, the &quot;Amended Agreement&quot;) to amend the Floor Price (as defined below) and the Cap Price (as defined below) for each Tranche 2 Component (as defined below), which were determined based on the volume weighted average price (the &quot;VWAP&quot;) of MasTec, Inc.'s common stock for a specified period ended on August 21, 2025, and to appropriately adjust the number of shares to be delivered on the respective valuation date for each Tranche 2 Component, with such adjustment resulting in a reduction in the number of 2024 Pledged Shares to 340,794 shares (the &quot; Pledged Shares&quot;). The Amended Agreement provides for the settlement of the transaction, at the reporting person's option, in cash or shares of MasTec, Inc. common stock.</footnote>
        <footnote id="F3">(Continued from Footnote 2) The Pledged Shares are divided into two tranches (each, a &quot;Tranche&quot;) of 15 components each (&quot;Tranche 1 Components&quot; or &quot;Tranche 2 Components&quot;). The number of shares of MasTec, Inc. common stock to be potentially delivered to the buyer on the valuation date of each Tranche 1 Component or Tranche 2 Component (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 MasTec, Inc. common stock on the valuation date for the applicable Tranche 1 Component or Tranche 2 Component (each, a &quot;Valuation Price&quot;) is less than or equal to $97.3535 (the &quot;Tranche 1 Floor Price&quot;) or $157.3441 (the &quot;Tranche 2 Floor Price,&quot; and each of the Tranche 1 Floor Price and Tranche 2 Floor Price, a &quot;Floor Price&quot;), respectively, then the reporting person will deliver to the buyer all of the Pledged Shares for the applicable Tranche 1 Component or Tranche 2 Component;</footnote>
        <footnote id="F4">(Continued from Footnote 3) (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 &quot;Tranche 1 Cap Price&quot;) or $243.0093 (the &quot;Tranche 2 Cap Price,&quot; and each of the Tranche 1 Cap Price and Tranche 2 Cap Price, a &quot;Cap Price&quot;), respectively, then the reporting person will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable Tranche 1 Component or Tranche 2 Component multiplied by the quotient of the applicable Floor Price divided by such Valuation Price; and</footnote>
        <footnote id="F5">(Continued from Footnote 4) (c) if such Valuation Price for the Tranche 1 Component or Tranche 2 Component exceeds the Tranche 1 Cap Price or Tranche 2 Cap Price, respectively, then the reporting person 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 (x) the applicable Floor Price plus such excess divided by (y) such Valuation Price.</footnote>
        <footnote id="F6">Each component is exercisable on the same date as it expires, which date for each component, is between August 17, 2026 and September 3, 2027.</footnote>
    </footnotes>

    <remarks>The reporting person currently retains ownership of all shares of MasTec common stock that are subject to the Amended Agreement and rights related thereto, including all voting rights.</remarks>
