On June 30, 2026, RPC entered into an Amended and Restated Credit Agreement (the "Credit Agreement”), between RPC, the Lenders party thereto, the Subsidiary Loan Parties party thereto and Bank of America, N.A., as Administrative Agent, which amended and restated the original Credit Agreement. The Amended Credit Agreement, among other things, extends the maturity date for revolving loans from June 22, 2027, to June 30, 2031, and removes the SOFR Adjustment to pricing. There were no other material changes to the original Credit Agreement which provides for a line of credit of up to $100 million, including a $35 million letter of credit sub-facility, and a $35 million swingline sub-facility. The Credit Agreement covenants contain customary terms and conditions, including restrictions on indebtedness, dividend payments, business combinations and other related items, as well as providing for acceleration of amounts due upon the occurrence of certain specified events of default. The Credit Agreement also includes a full and unconditional guarantee by the Company's 100% owned domestic subsidiaries whose assets equal substantially all of the consolidated assets of the Company and its subsidiaries. Certain of the Company’s minor subsidiaries are not guarantors. Additionally, the Credit Agreement permits the issuance of letters of credit in currencies other than U.S. dollars.

Under the Credit Agreement, when RPC’s trailing four quarter Adjusted EBITDA (as calculated under the Credit Agreement) is equal to or greater than $50 million: (i) the consolidated leverage ratio cannot exceed 2.50:1.00 and (ii) the debt service coverage ratio must be equal to or greater than 2.00:1.00; otherwise, the minimum tangible net worth must be greater than or equal to $400 million.

Revolving loans bear interest at one of the following two rates at the Company’s election:

●Term Secured Overnight Financing Rate (Term SOFR); plus, a margin ranging from 1.25% to 2.25%, based on a quarterly consolidated leverage ratio calculation, and

●the Base Rate, which is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) Bank of America’s publicly announced, “prime rate,” (c) the Term SOFR plus 1.00%, and (d) 1.00%; in each case plus a margin that ranges from 0.25% to 1.25% based on a quarterly consolidated leverage ratio calculation.

In addition, the Company pays an annual fee ranging from 0.20% to 0.30%, based on a quarterly consolidated leverage ratio calculation, on the unused portion of the credit facility.

The Company incurred approximately $258 thousand of costs associated with the Amended Credit Agreement. These costs are being amortized to interest expense over the remaining term of the loan, and the unamortized balance is classified as part of non-current other assets. As of June 30, 2026, RPC had no outstanding borrowings under the revolving credit facility, and letters of credit outstanding relating to self-insurance programs and contract bids totaled $18.2 million; therefore, a total of $81.8 million of the facility was available.

The Company assumed a Seller Note as part of the Pintail acquisition. Interest incurred includes interest on the Seller Note, facility fees on the unused portion of the revolving credit facility and the amortization of loan costs. Interest paid includes amounts due on the Seller Note and the credit facility. These amounts are presented below for the periods indicated:
