On October 31, 2024, the Company entered into the New Credit Agreement providing for the New 2024 Term Loan Facilities due October 31, 2031, in an aggregate principal amount of $2,250.0 million, and the New 2024 Revolving Credit Facility due October 31, 2029, in an aggregate principal amount of up to $750.0 million. Concurrent with the closing of the New Credit Agreement, the Company used the proceeds of the New 2024 Term Loan Facilities and approximately $95.0 million of the proceeds of the New 2024 Revolving Credit Facility to repay in full amounts outstanding under (i) the Prior Credit Agreement and (ii) the Prior ABL Credit Agreement, terminating each of the debt facilities thereunder. The Company expensed $23.7 million related to new third party fees that did not meet the criteria for deferral as refinancing costs on the Consolidated Income Statement during the year ended December 31, 2024, of which $5.7 million related to the New Credit Agreement, $11.6 million related to the New 2024 Term Loan Facilities, $1.5 million related to the September 6, 2024 amendment to the Prior Credit Agreement and $4.9 million related to the March 25, 2024 Prior Credit Agreement.

The New Credit Agreement provided for (i) a senior secured dollar term loan B facility, incurred by the U.S. Borrower in an aggregate principal amount of $1,630.0 million (the “New 2024 Term Loan B-1 Facility”), (ii) a senior secured dollar term loan B facility incurred by the Canadian Borrower in an aggregate principal amount of $620.0 million (the “New 2024 Term Loan B-2 Facility” and, together with the New 2024 Term Loan B-1 Facility, the “New 2024 Term Loan Facilities”). The New 2024 Term Loan Facilities were fully drawn on October 31, 2024, in an aggregate principal amount of $2,250.0 million, bearing interest at a Secured Overnight Financing Rate (“SOFR”) + 2.25% with provision for a rate step-down to 2.00% based on achieving a consolidated First Lien Net Leverage Ratio (as defined in the New Credit Agreement) of less than 3.00x, and will mature on October 31, 2031. The Company incurred new third party fees of $13.2 million related to the New 2024 Term Loan Facilities of which $11.6 million were expensed as refinancing costs on the Consolidated Income Statement during the year ended December 31, 2024, and $1.6 million of deferred finance charges were recorded as a reduction of long-term debt on the Consolidated Balance Sheets as of December 31, 2024 and will be amortized on a straight-line basis over the term of the credit facility. As of March 31, 2025, the effective interest rate on the New 2024 Term Loan Facilities was SOFR + 2.00%.

The New Credit Agreement provided for a senior secured multicurrency revolving credit facility available to the Company in an aggregate principal amount of up to $750.0 million (of which up to $150.0 million is available for the issuance of letters of credit) (the “New 2024 Revolving Credit Facility” and, together with the New 2024 Term Loan Facilities, the “New Senior Secured Credit Facilities”). The New 2024 Term Loan Facilities will mature on October 31, 2031, and the New 2024 Revolving Credit Facility will mature on October 31, 2029. As of December 31, 2024, the New 2024 Revolving Credit Facility had no outstanding borrowings. Borrowings bear interest at SOFR + 2.00% with provision for step-down to 1.75% and 1.5% based on a achieving a consolidated First Lien Net Leverage Ratio of less than 3.25x and 2.75x, respectively. As of March 31, 2025, we had $624.1 million of available borrowing capacity under the New 2024 Revolving Credit Facility. The Company incurred new lender fees of $3.8 million related to the New 2024 Revolving Credit Facility, which are recorded as an other long-term asset on the Consolidated Balance Sheets as of December 31, 2024, and will be amortized on a straight-line basis over the term of the facility. As of March 31, 2025, the effective interest rate on the New 2024 Revolving Credit Facility was SOFR + 1.75%.

On October 31, 2024, concurrent with the closing of the New Credit Agreement, the Company used the proceeds of the New 2024 Term Loan Facilities and the New 2024 Revolving Credit Facility to repay in full amounts outstanding under the Prior Credit Agreement terminating each of the debt facilities thereunder, which resulted in a loss on extinguishment of debt of $4.7 million recognized in the year ended December 31, 2024, $0.7 million related to the March 25, 2024 amendment of the Prior Credit Agreement, $3.6 million upon the commencement of the New Credit Agreement on October 31, 2024 representing the write off unamortized discounts and deferred financing charges related to the extinguished portions of the Prior Term Loan facilities and $0.4 million related to the extinguishment of the Prior 2023 Revolving Credit Facility.

On August 24, 2023, the Company amended the Prior Credit Agreement to combine the 2019 Term Loan Facilities and the 2021 Term Loan Facility into the Prior 2023 Term Loan Facilities in the amount of $2,575.0 million less a 1.0% discount. The Prior 2023 Term Loan Facilities were comprised of two tranches, referred to as the Prior 2023 Term Loan B-1 Facility and the Prior Term Loan B-2 Facility, with identical terms that were entered into by subsidiaries of the Company. The Prior 2023 Term Loan Facilities incurred interest at the Term SOFR Rate plus 3.75% to 4.00% or the Base Prime Rate plus 2.75% to 3.00% and were scheduled to mature on August 24, 2028. As a result of the amendment, both a debt modification and a debt extinguishment arose. The Company recognized $0.8 million in deferred charges related to the Prior 2023 Term Loan Facilities which are recorded as a reduction of long-term debt on the Consolidated Balance Sheets. The Company also recognized a loss on the extinguishment of debt of $6.2 million, representing the write-off of the unamortized deferred finance charges and original issue discount related to the extinguished portion of the 2019 Term Loan Facilities and 2021 Term Loan Facility, while $22.8 million of the unamortized deferred finance charges and original issue discount relating to the modified debt continued to be deferred. In addition, $19.9 million in third party fees related to the modified portion of the 2019 Term Loan Facilities were expensed as refinancing costs on the Consolidated Income Statement during the year ended December 31, 2023, as these costs did not meet the criteria for deferral.

On March 25, 2024, the Company amended its Prior Credit Agreement, dated as of April 4, 2019 (as amended, restated, modified and/or supplemented from time to time, the “Credit Agreement”), among Dynasty Acquisition Co., Inc. as the U.S. borrower (the “U.S. Borrower”), Standard Aero Limited, as the Canadian borrower (the “Canadian Borrower”), Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent, and certain other parties thereto, to refinance the $2,562.1 million existing senior secured term loans then-outstanding thereunder (the “Prior 2023 Term Loans”) and provide the Company with an incremental $200.0 million as additional term loans (together with the refinanced 2023 Term Loans, the “Prior 2024 Term Loans” and the facilities in respect thereof, the “Prior 2024 Term Loan Facilities”). In addition, the amendment reduced the applicable interest rate to the Term SOFR Rate plus 3.25% to 3.50% or the Base Prime Rate plus 2.25% to 2.50%. All other terms of the Credit Agreement remained unchanged. The incremental proceeds from the Prior 2024 Term Loans were used toward the partial redemption of the Prior Senior Notes. As a result of the amendment, the Company recognized a loss on the extinguishment of debt of $0.7 million in the year ended December 31, 2024, representing the write-off of the unamortized deferred finance charges related to the extinguished portion of the Prior 2023 Term Loans. In addition, $4.9 million in third party fees related to the modified portion of the Term Loans were expensed as refinancing costs on the Consolidated Income Statement during the year ended December 31, 2024, as these costs did not meet the criteria for deferral. The Company recognized $0.1 million in deferred charges which are recorded as a reduction of long-term debt on the Consolidated Balance Sheets. The original issue discount and deferred charges were amortized over the term of the Credit Agreement using the straight-line method, which approximates the effective interest rate method.

On September 6, 2024, the Company amended the Prior Credit Agreement to incur additional 2024 Term Loans in a principal amount of $200.0 million which were, in part, used to paydown a portion of the advances under the Company’s Prior ABL Credit Facility used to fund the acquisition of Aero Turbine. There were no other substantive changes made to the Prior Credit Agreement. As a result of the amendment, $1.5 million in third party fees related to the modified portion of the Term Loans were expensed as refinancing costs on the Consolidated Income Statement during the year ended December 31, 2024, as these costs did not meet the criteria for deferral. The original issue discount and deferred charges were amortized over the term of the Prior Credit Agreement using the straight-line method, which approximates the effective interest rate method.

On October 31, 2024 concurrent with the New Credit Agreement, we recognized a $3.6 million loss on extinguishment of debt representing the write off unamortized discounts and deferred financing charges related to the extinguished portions of the Prior Term Loan facilities

The Prior 2023 Revolving Credit Facility was a senior secured multicurrency cash flow revolving credit facility available under the Prior Credit Agreement, with a capacity of $150.0 million (of which up to $75.0 million was available for the issuance of letters of

credit) and was scheduled to mature on May 1, 2028. The Prior 2023 Revolving Credit Facility bore interest at the Adjusted Term SOFR rate plus 3.125% to 3.50%. The applicable rates on borrowing under the credit agreement were based on the Consolidated First Lien Net Leverage Ratio. The 2023 Revolving Credit Facility was subject to a maximum Consolidated First Lien Net Leverage Ratio that was tested at the end of any fiscal quarter if the total revolving credit loans outstanding under the Prior 2023 Revolving Credit Facility on such date exceed 35.0% of the aggregate amount of all commitments in respect of the Prior 2023 Revolving Credit Facility.

On October 31, 2024, concurrent with the closing of the New Credit Agreement, the Company terminated the Prior 2023 Revolving Credit Facility which had no outstanding loans under it, resulting in a loss on extinguishment of debt of $0.4 million recognized in the year ended December 31, 2024.

The Prior ABL Credit Facility had a capacity of $400.0 million, was repayable in U.S. dollars and was scheduled to mature on May 1, 2028. At the Company’s discretion, the borrowings under the ABL Credit Facility bore interest at the Adjusted Term SOFR rate plus 1.50% to 2.00%, Prime Lending Rate plus 0.50% to 1.00%, or the Base Rate on Canadian borrowings plus 0.50% to 1.00%, with the spread dependent on the amount of the borrowing and was subject to certain financial covenants. The ABL Credit Facility had an annual commitment fee of 0.250% to 0.375% based on excess availability. The ABL Credit Facility contained financial covenants which were required to be calculated immediately prior to or during the continuance of a trigger period. The trigger period was a period where borrowing availability was less than the greater of 10% of the line cap and $30.0 million.

The Prior Senior Notes bore an interest rate of 10.0% and were scheduled to mature on April 4, 2027. On March 25, 2024, the Company partially redeemed $200.0 million of the Prior Senior Notes. As a result of the redemption, the Company recognized a loss on extinguishment of debt of $2.9 million in the year ended December 31, 2024, representing the write-off of the unamortized deferred finance charges related to the redeemed portion of the Prior Senior Notes. On October 3, 2024, the Company used the proceeds from the initial public offering to repay the full outstanding principal and accrued interest on the Prior Senior Notes, totaling $487.5 million. The extinguishment of the Prior Senior Notes resulted in a loss on extinguishment of debt of $5.7 million recognized in the year ended December 31, 2024.

The Company’s weighted average interest rate of borrowings under its senior credit agreements was 6.6% for the three months ended March 31, 2025, and 9.5% for the three months ended March 31, 2024.

Certain of these agreements contain non-financial covenants that limit both the Company’s ability to raise additional financings in the future and the Company’s ability to pay dividends subject to select amounts and incurrence ratios.
