In connection with the KKR Acquisition, the Company and a group of financial institutions entered into a credit agreement (the “Credit Agreement”) dated December 18, 2013. The Credit Agreement consisted of seven-year $1,460.0 term loans (“First Lien

Term Loans”) and a five-year $210.0 revolving credit facility. All amounts outstanding under the Credit Agreement were collateralized by substantially all of the assets of the Company.

On April 22, 2022, the Company, entered into Amendment No. 6 to the Credit Agreement (the “Amendment Agreement”). Under the terms of the Amendment Agreement, the existing Credit Agreement was amended to provide for: (i) a $1,200.0 seven-year term loan (the “Series B Term Loan”) and (ii) a $300.0 five-year revolving credit facility (the “Revolving Credit Facility”). The Series B Term Loan matures on April 22, 2029 and bears interest at a rate per annum of a secured overnight financing rate (“Term SOFR”), plus a margin of either 3.25% or 3.00% or a base rate (“ABR”) plus a margin of either 2.25% or 2.00%, subject to SOFR and ABR floors of 0.50% and 1.50%, respectively, with the margin on the Series B Term Loan determined based on the Company’s first lien net leverage ratio. The Company used the net proceeds from the Series B Term Loan to repay all amounts outstanding under the Credit Agreement as in effect prior to the Amendment Agreement. An original issue discount of $12.0 was incurred when the Series B Term Loan was issued and is being amortized using the effective interest method over the life of the debt, resulting in an effective yield of 3.42%. Debt repayments for the Series B Term Loan totaled $6.0 for the six months ended March 31, 2023.

On August 28, 2023, the Company voluntarily repaid $450.0 of the amount outstanding under the Company’s Amendment Agreement.

On August 31, 2023, the Company entered into Amendment No. 7 to the Credit Agreement (the “Credit Agreement Amendment”). The Credit Agreement Amendment (i) amends the definition of “Permitted Holders” to include Birch Equity Holdings, LP, a Delaware limited partnership, Birch-OR Equity Holdings, LLC, a Delaware limited liability company and One Rock Capital Partners, LLC and (ii) provides for a 1.00% prepayment premium for voluntary prepayments made in connection with repricing transactions or amendments made where the primary purpose of which is to decrease the effective yield, and which shall be applicable until six months after entering into the Credit Agreement Amendment.

The Company has a five-year $300.0 revolving credit facility (the “Revolving Credit Facility”) that matures on April 22, 2027 and bears interest at a rate per annum of Term SOFR plus a margin ranging from 2.00% to 2.50% or ABR plus a margin ranging from 1.00 to 1.50%, subject to SOFR and ABR floors of 0.00% and 1.00%, respectively, with the margin on the Revolving Credit Facility determined based on the Company’s first lien net leverage ratio. The Revolving Credit Facility replaced the previous $260.0 revolving credit facility under the Credit Agreement as in effect prior to the Amendment Agreement. During the six months ended March 31, 2023 the Company borrowed and repaid $33.5 against the capacity. The Company had $42.6 of letters of credit issued and outstanding as of March 31, 2024 and September 30, 2023.

On June 22, 2022, the Company entered into the Third Amendment to the Receivables Financing Agreement (the "Third Amendment") which extended the term through June 22, 2025 and increased the borrowing capacity to $275.0. All amounts outstanding under the Receivables Financing Agreement are collateralized by substantially all of the accounts receivable and unbilled revenue of the Company. During the six months ended March 31, 2024 the Company borrowed $0.5 against the capacity and voluntarily repaid $9.5. During the six months ended March 31, 2023 the Company borrowed $298.0 against the capacity and voluntarily repaid $279.5.
