MasTec, Inc. Announces Amendment of Exchange Offer and Consent Solicitation

Coral Gables, FL (September 26, 2022) — MasTec, Inc. (NYSE: MTZ) (the “Company”) today announced its amendment of the terms of its private exchange offer to certain Eligible Holders (as defined herein) (the “Exchange Offer”) for any and all outstanding 6.625% Senior Notes due August 15, 2029 (the “IEA Existing Notes”) issued by IEA Energy Services LLC (the “IEA Issuer”), a subsidiary of Infrastructure and Energy Alternatives, Inc. (“IEA”), for up to an aggregate principal amount of $300,000,000 of new 6.625% MasTec Senior Notes due August 15, 2029 issued by the Company (the “MTZ Exchange Notes”). The Company has amended the Exchange Offer to extend (i) the Consent Deadline and (ii) the Early Tender Date (each as defined herein). Except as otherwise described in this press release, the terms and conditions of the Exchange Offer set forth in the Offering Memorandum (as defined herein) remain unchanged.

The Exchange Offer and Consent Solicitation are being conducted in connection with, and are conditioned upon the completion of, the previously announced merger in which IEA would become a wholly owned subsidiary of the Company (the “Merger”), which is currently expected to close in October 2022, subject to customary closing conditions, regulatory approvals and approval by the stockholders of IEA.

As part of the Exchange Offer, the Company is soliciting consents (the “Consent Solicitation”) with respect to the IEA Existing Notes, to eliminate or modify certain of the covenants, restrictive provisions and events of default (the “Proposed Amendments”) in the indenture, dated as of August 17, 2021, governing the IEA Existing Notes. The Proposed Amendments require the valid consent of the holders of not less than a majority in principal amount of IEA Existing Notes, excluding IEA Existing Notes held by certain affiliated holders of IEA (the “Requisite Consents”).

The Company has amended the Early Tender Date to be 5:00 p.m., New York City time, on October 14, 2022 (such date and time, as the same may be further extended, the “Early Tender Date”). In addition, the Company has amended the Consent Deadline to be the earlier of (i) 5:00 p.m., New York City time, on October 14, 2022 and (ii) 5:00 p.m., New York City time, on the date the Requisite Consents are obtained (such date and time, as the same may be further extended, the “Consent Deadline”). As amended hereby, the Early Tender Date, the Consent Deadline and the Expiration Date (as defined in the Offering Memorandum) will each occur at 5:00 p.m., New York City time, on October 14, 2022.

Subject to applicable law, the Company expressly reserves the right, in its sole discretion, to amend the Exchange Offer and Consent Solicitation in any respect, including to (i) extend the Early Tender Date without extending the Consent Deadline, (ii) extend the Consent Deadline or (iii) provide that the Early Tender Premium (as defined in the Offering Memorandum) will be payable only to Eligible Holders who validly tender and do not validly withdraw IEA Existing Notes at or prior to the Consent Deadline.

At any time before the Expiration Date, if the Company receives the Requisite Consents, the IEA Issuer has agreed that the IEA Issuer, IEA and the trustee of the IEA Existing Notes will execute and deliver a supplemental indenture relating to the Proposed Amendments, which will be effective upon execution on the date the Requisite Consents are obtained but will only become operative upon the settlement date of the Exchange Offer. An Eligible Holder that validly tenders (and does not validly withdraw) its IEA Existing Notes and validly delivers a consent prior to the Consent Deadline, but validly withdraws such IEA Existing Notes after the Consent Deadline but prior to the Expiration Date, will receive the Consent Payment (as defined in the Offering Memorandum), even if such Eligible Holder is no longer the beneficial owner of such IEA Existing Notes at the Expiration Date, but will not receive the Early Tender Premium or the Exchange Consideration (as defined in the Offering Memorandum).

The Company, at its option, may complete the Exchange Offer even if the Requisite Consents are not received. Any amendment or waiver of the terms of or conditions with respect to the Exchange Offer by the Company will automatically amend or waive such terms or conditions with respect to the Consent Solicitation unless expressly stated otherwise.

The Exchange Offer and Consent Solicitation are being made pursuant to the terms and subject to the conditions set forth in the offering memorandum, dated August 8, 2022, as amended by the Offering Memorandum Supplement, dated August 22, 2022 (as so amended, the “Offering Memorandum”), as such terms and conditions are amended by this press release, and are conditioned upon the closing of the Merger, which condition may not be waived by the Company, and certain other conditions that may be waived by the Company. The Exchange Offer and Consent Solicitation will expire on the Expiration Date, unless extended or terminated.

Tenders of IEA Existing Notes may be validly withdrawn by Eligible Holders at any time prior to the Expiration Date; however, a valid withdrawal of tendered IEA Existing Notes before the Expiration Date will not be deemed a valid revocation of the related consent delivered by such Eligible Holder, and such consent will continue to be deemed delivered. Any consents to the Proposed Amendments delivered prior to the Consent Deadline (including any consents delivered prior to the date hereof) may not be revoked.

Documents relating to the Exchange Offer and Consent Solicitation will only be distributed to persons who certify that they are (a) a “Qualified Institutional Buyer,” as that term is defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), or (b) a person that is not a U.S. person (as defined in Regulation S under the Securities Act) (such persons, “Eligible Holders”). The complete terms and conditions of the Exchange Offer and Consent Solicitation are described in the Offering Memorandum, copies of which may be obtained by contacting D.F. King & Co., Inc., the exchange agent and information agent in connection with the Exchange Offer and Consent Solicitation, by telephone at (800) 549-6864 (U.S. toll-free) or (212) 269-5550 (banks and brokers), or by email at mastec@dfking.com. The eligibility certification may be completed at www.dfking.com/mastec or is also available by contacting D.F. King & Co., Inc. using the information above.

The MTZ Exchange Notes have not been, and will not be, registered with the Securities and Exchange Commission (the “SEC”) under the Securities Act, or any state or foreign securities laws. The MTZ Exchange Notes may not be offered or sold in the United States or to any U.S. person except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act.

No offer, solicitation, purchase or sale will be made in any jurisdiction in which such an offer, solicitation or sale would be unlawful. The Exchange Offer and Consent Solicitation are being made solely pursuant to the Offering Memorandum and only to such persons and in such jurisdictions as are permitted under applicable law.
