      <div>&#160;</div>
      <div style="text-align: justify; color: rgb(0, 0, 0);">We have audited the accompanying statements of net assets available for benefits of The MasTec, Inc. 401(k) Retirement Plan (the &#8220;Plan&#8221;) as of December 31, 2021 and 2020, the related statement of
        changes in net assets available for benefits for the year ended December 31, 2021, and the related notes (collectively, the &#8220;financial statements&#8221;). In our opinion, the financial statements present fairly, in all material respects, the net assets
        available for benefits of the Plan as of December 31, 2021 and 2020, and the changes in net assets available for benefits for the year ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of
        America.</div>

      <div>&#160;</div>
      <div style="text-align: justify; color: rgb(0, 0, 0);">These financial statements are the responsibility of the Plan&#8217;s management. Our responsibility is to express an opinion on the Plan&#8217;s financial statements based on our audits. We are a public
        accounting firm registered with the Public Accounting Oversight Board (United States) (&#8220;PCAOB&#8221;) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations
        of the Securities and Exchange Commission and the PCAOB.</div>
      <div>&#160;</div>
      <div style="text-align: justify; color: rgb(0, 0, 0);">We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial
        statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to
        obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan&#8217;s internal control over financial reporting. Accordingly, we express no such opinion.</div>

      <div style="text-align: justify; font-family: 'Times New Roman',Times,serif;"><font style="font-family: 'Times New Roman'; color: rgb(0, 0, 0);">Our audits included performing procedures to assess the risk of material misstatement of the financial
          statements, whether due to error or fraud, and performing procedures that respond to those risks. </font><font style="font-family: 'Times New Roman';">Such procedures included <font style="color: rgb(0, 0, 0);">examining, on a test basis,
            evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by the Plan&#8217;s management, as well as evaluating the overall
            presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.</font></font></div>

      <div style="text-align: justify; color: rgb(0, 0, 0);">The supplemental information in the accompanying Schedule H, line 4a &#8211; Schedule of Delinquent Deposits of Participant Contributions for the year ended December 31, 2021 and Schedule H, line 4i &#8211;
        Schedule of Assets (Held at End of Year) as of December 31, 2021 have been subjected to audit procedures performed in conjunction with the audit of the Plan&#8217;s financial statements. The supplemental information is presented for the purpose of
        additional analysis and is not a required part of the financial statements but included supplemental information required by the Department of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security
        Act of 1974. The supplemental information is the responsibility of the Plan&#8217;s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other
        records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental
        information, including its form and content, is presented in conformity with the Department of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental
        information is fairly stated, in all material respects, in relation to the financial statements as a whole.</div>

        period&#8221;). Employees enter the Plan on the first day of the month coinciding with or the next month following the date on which they meet the eligibility requirements. The Plan is subject to the provisions of the Employee Retirement Income Security
        Act of 1974 (&#8220;ERISA&#8221;), as amended. The Plan&#8217;s trustee, custodian and recordkeeper is Bank of America Merrill Lynch (&#8220;Merrill Lynch&#8221;).&#160; The Investment Committee is responsible for oversight of the Plan and determines the appropriateness of the

        percent employer match. The match is credited on a quarterly basis, in the months of April, July, October of the current year, and January of the following year. The Company&#8217;s matching contribution is funded 50 percent in the form of the Company&#8217;s
        common stock, and 50 percent in cash, which is invested in accordance with each participant&#8217;s investment directive. Company&#8217;s matching contributions are vested immediately. Participants can change their investment options with respect to the
        matching contributions made in the form of the Company&#8217;s common stock as soon as the matching contribution is funded, subject to the terms of the Plan.</div>

        catch-up contributions to the Plan. Upon enrollment, a participant may direct employee contributions, in 1 percent increments, into various investment options offered by the Plan. Participants may change their investment options daily.</div>

        at the date of the loan. The annual interest rate charged on participant loans outstanding during the year ended December 31, 2021 ranged from 3.25 percent to 6.50 percent. Loan terms range from 1 to 5 years or may exceed 5 years for the purchase
        of a primary residence. Loans provide level amortization for repayments to be made not less frequently than on a quarterly basis. Principal and interest is paid ratably through payroll deductions. Participants pay certain administrative expenses
        associated with the loan. If any scheduled loan repayments remain outstanding for greater than 90 days, the participant loan will be placed in default and reported as deemed distribution.</div>

      <div><br>
      </div>
      <div style="text-align: justify;">The Plan adopted the Prototype Non-standardized Profit-Sharing Plan from Merrill Lynch and the Plan received an opinion letter dated March 31, 2014, that the Plan and related trust are designed in accordance with
        applicable sections of the Internal Revenue Code (IRC). Although the Plan has been amended since receiving the determination letter, the Plan administrator and the Plan&#8217;s tax counsel believe that the Plan is designed, and is currently being
        operated, in compliance with the applicable requirements of the IRC and, therefore, believe that the Plan is qualified, and the related trust is tax-exempt.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the plan and recognize a tax liability if the plan has taken an uncertain position
        that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.</div>

      <div style="text-align: justify; color: rgb(0, 0, 0);">The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risk. Due to the level of risk associated with
        certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that these risks in the near term would materially affect participants&#8217; account balances and the
        amounts reported in the statement of net assets available for benefits.</div>

        Company. These transactions constitute prohibited transactions as defined by ERISA. The Company is aware of the occurrence and has taken the appropriate steps to correct the situation. Estimated interest assessed on these amounts were $19 and $2,
        for the years ended December 31, 2021 and 2020, respectively. The Company has chosen to correct this without use of the Voluntary Fiduciary Contribution Program. Furthermore, the Company does not believe that these prohibited transactions will have
