As previously disclosed, Construction Partners, Inc. (the ?Company?), certain of its wholly owned subsidiaries in their capacity as co-borrowers (collectively with the Company, the ?Borrowers?), and certain of the Company?s wholly owned subsidiaries in their capacity as guarantors (collectively with the Borrowers, the ?Loan Parties?) are party to that certain Third Amended and Restated Credit Agreement with PNC Bank, National Association, as successor to BBVA USA, as administrative agent and lender (the ?Administrative Agent?), PNC Capital Markets LLC, as joint lead arranger and sole bookrunner, Regions Bank and BofA Securities, Inc., each as a joint arranger, and certain other lenders party thereto (as amended from time to time, the ?Credit Agreement?). The Credit Agreement, which originally provided for (i) a revolving credit facility in an initial aggregate principal amount of $325.0 million (the ?Revolving Credit Facility?), (ii) a term loan facility in an initial aggregate principal amount of $250.0 million (the ?Term Loan?), and (iii) a delayed draw term loan facility in an initial aggregate principal amount of $50.0 million (the ?Delayed Draw Term Loan?), permitted the Borrowers to request one or more incremental term loans or an increase in the commitments under the Revolving Credit Facility (in either case, an ?Incremental Facility?) in an aggregate principal amount of up to the greater of (i) $200.0 million and (ii) the amount of the consolidated adjusted EBITDA of the Loan Parties for the immediately preceding four-fiscal-quarter period, on the same terms as the Term Loan or the Revolving Credit Facility, as applicable, including pricing, and, in the case of an Incremental Facility that is a term loan, the then-applicable amortization rate. On May 29, 2024 (the ?Effective Date?), the Loan Parties entered into the Third Amendment to the Credit Agreement (the ?Amendment,?

and the Credit Agreement, as amended by the Amendment, the ?Amended Credit Agreement?), pursuant to which, among other things, (i) the aggregate commitments under the Revolving Credit Facility were increased from $325.0 million to $400.0 million (as so increased, the ?Increased Revolving Credit Facility?) and (ii) $125.0 million of borrowings previously outstanding under the Revolving Credit Facility were reallocated from the Revolving Credit Facility to the Term Loan (as so increased, the ?Increased Term Loan?). In addition, in connection with the Amendment, each of South State Bank, First-Citizens Bank & Trust Company and Comerica Bank became a Revolving Credit Lender and Term Lender (each as is defined in the Amended Credit Agreement). The Amended Credit Agreement also includes, among other things, updates to certain affirmative and negative covenants, and provides that an additional Incremental Facility remains available to the Loan Parties on the same terms and conditions described above.

As of the Effective Date, after giving effect to the Amendment, $98.1 million of principal was outstanding under the Increased Revolving Facility, and (ii) approximately $401.3 million of principal was outstanding under the Increased Term Loan. Except as modified by the Amendment, the terms of the Revolving Credit Facility and the Term Loan remain the same. The lenders that are parties to the Amended Credit Agreement and their respective affiliates are full-service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage, and other financial and non-financial activities and services.

Certain of these financial institutions and their respective affiliates have provided, and may in the future provide, certain of these services to the Loan Parties and to persons and entities with relationships with the Loan Parties, for which they received or will receive customary fees and expenses.
