Introductory Note

On July 1, 2025, Astec Industries, Inc. (the "Company") completed its previously announced acquisition of TerraSource Holdings, LLC, a Delaware limited liability company (“TerraSource”), pursuant to that certain Membership Interest Purchase Agreement, dated as of April 28, 2025, by and among the Company, TerraSource, RLI TSG Holdings LLC, Milacron LLC and the other seller parties thereto (collectively, the “Sellers”), and RLIH, LLC (the “Sellers’ Representative”) (the “Purchase Agreement” and the transactions contemplated thereby, the “Acquisition”). The events described in this Current Report on Form 8-K (this “Current Report”) are related to the closing of the Acquisition (the “Closing”).

Item 1.01. Entry Into a Material Definitive Agreement.

Simultaneously with the Closing, on July 1, 2025 (the “Financing Effective Date”), the Company entered into a credit agreement (the “Credit Agreement”) that provides for (i) a revolving credit facility, a term loan facility, a swingline facility and a letter of credit facility, in an initial aggregate amount of up to $600,000,000, and (ii) an incremental facilities limit in an aggregate amount not to exceed $150,000,000 (collectively, the “Credit Facilities”).

The Credit Agreement was entered into by and among the Company, as borrower, Wells Fargo Bank, National Association, as administrative agent, and the lenders party thereto from time to time. The proceeds of (i) the revolving credit facility, letter of credit facility and swingline facility will be used (a) to finance capital expenditures, (b) for working capital and other general corporate purposes of the Company and its subsidiaries, and (c) in the case of letters of credit, for the backstop or replacement of letters of credit existing prior to the Financing Effective Date and to support general corporate purposes, and (ii) the term loan facility will be used on the Financing Effective Date, together with cash on hand, to (a) finance the Acquisition, (b) repay existing indebtedness of the Company and its subsidiaries, including repayment of all amounts outstanding under the Previous Credit Facility (as defined below), and (c) the payment of transaction expenses incurred in connection with the Acquisition and the Credit Facilities.

Loans advanced under the revolving credit facility and the term loan facility must be repaid on (i) July 1, 2030 or (ii) earlier as specified in the Credit Agreement.

At the Company’s election, revolving credit loans and term loans advanced under the Credit Agreement shall bear interest at a rate per annum equal to (i) a forward-looking term rate based on the secured overnight financing rate for the applicable interest period (“Term SOFR”), as selected by the Company, plus an applicable margin ranging between 1.75% and 2.75% per annum, or (ii) the highest of the Wells Fargo Bank, National Association prime rate, the Federal Funds rate plus 0.50%, and Term SOFR for a one month tenor in effect on such day plus 1.00% (“Base Rate”), plus an applicable margin ranging between 0.75% and 1.75% per annum. Swingline loans shall bear interest at the Base Rate, plus an applicable margin ranging between 0.75% and 1.75% per annum.

The Company also pays a commitment fee ranging from 0.15% to 0.35% per annum to the lenders under the revolving credit facility on the average amount by which the aggregate commitments of the lenders exceed utilization of the revolving credit facility. The applicable margins and the commitment fee are determined based on the Company's Consolidated Total Net Leverage Ratio (as defined in the Credit Agreement) at the relevant time.

The obligations of the Company in respect of the Credit Facilities are secured and are guaranteed by the US domestic subsidiaries of the Company, subject to customary exceptions.

The Credit Agreement includes certain affirmative and negative covenants that impose restrictions on the Company's financial and business operations, including limitations on liens, indebtedness, fundamental changes, and changes in the nature of the Company's business. These limitations are subject to customary exceptions. The Company is also required to maintain a (i) Consolidated Total Net Leverage Ratio of not more than 3.50 to 1.00 as of the last day of any fiscal quarter, which may be increased to 4.00 to 1.00 in connection with a material permitted acquisition and subject to the terms of the Credit Agreement, and (ii) Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of at least 2.50 to 1.00 as of the last day of any fiscal quarter. The Credit Agreement also contains customary representations and warranties.

The Credit Agreement contains events of default customary for this type of financing, including a cross default and cross acceleration provision to certain other material indebtedness of the Company and its subsidiaries. Upon the occurrence of an event of default, the outstanding obligations under the Credit Agreement may be accelerated and become due and payable immediately. In addition, if certain change of control events occur with respect to the Company, the Company is required to repay the loans outstanding under the Credit Facilities.

In connection with the entry into the Credit Facilities, the Company (i) repaid all outstanding borrowings under its prior $250 million revolving credit facility pursuant to that certain Credit Agreement, dated as of December 19, 2022, between the Company and Wells Fargo Bank, National Association (the “Previous Credit Facility”), utilizing borrowings under the Credit Facilities, and (ii) terminated the Previous Credit Facility.
