On October 24, 2024, the Company entered into an Amended and Restated Credit Agreement (the "Credit Facility") with a banking syndicate. The amended agreement matures on October 3, 2027, with an option to extend on an annual basis, subject to certain conditions. The agreement is comprised solely of a revolving facility that includes a Canadian dollar tranche of $300.0 million (up from $280.0 million) and an Australian dollar tranche of $250.0 million AUD (up from $220.0 million AUD), totaling $522.6 million of lending capacity using the exchange rate in effect as at December 31, 2024. The Credit Facility permits finance lease obligations to a limit of $400.0 million (up from $350.0 million) and certain other borrowings outstanding to a limit of $20.0 million. The permitted amount of $400.0 million for finance lease obligations includes guarantees provided by the Company to certain joint ventures. During the year ended December 31, 2024, financing costs of $1.0 million were incurred in connection with the amended Credit Facility and are recorded in other assets on the Consolidated Balance Sheets.

As at December 31, 2024, there was $34.0 million (December 31, 2023 - $31.3 million) in issued letters of credit under the Credit Facility and the unused borrowing availability was $92.7 million (December 31, 2023 - $129.3 million).

As at December 31, 2024, there was an additional $86.7 million in borrowing availability under finance lease obligations (December 31, 2023 - $60.1 million). Borrowing availability under finance lease obligations considers the current and long-term portion of finance lease obligations and financing obligations, including the finance lease obligations for the joint ventures that the Company guarantees.

◦"Bank EBITDA" is defined as earnings before interest, taxes, depreciation and amortization, excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial instruments, cash and non-cash stock-based compensation expense, gain or loss on disposal of property, plant and equipment, acquisition costs, and certain other non-cash items included in the calculation of net income.

The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, Australian Bank Bill Swap Reference Rate ("BBSY"), Canadian bankers’ acceptance rate or the Secured Overnight Financing Rate ("SOFR") (all such terms as used or defined in the Credit Facility), plus applicable margins. The Company is also subject to non-refundable standby fees, 0.40% to 0.70% depending on the Company's Total Debt to Bank EBITDA Ratio.

The Company acts as a guarantor for drawn amounts under revolving equipment lease credit facilities which have a combined capacity of $115.0 million for Mikisew North American Limited Partnership ("MNALP"), an affiliate of the Company. This equipment lease credit facility will allow MNALP to avail the credit through a lease agreement and/or equipment finance contract with appropriate supporting documents. As at December 31, 2024, the Company has provided guarantees on this facility of $61.7 million. At this time, there have been no instances or indication that payments will not be made by MNALP.

The 5.50% convertible debentures are redeemable on and after to June 30, 2024, and prior to June 30, 2026 at the option of the Company at the redemption price equal to the principal amount of the debentures plus accrued and unpaid interest thereon up to but excluding the date set for redemption provided, among other things, the current market price is at least 125% of the conversion price on the date on which notice of the redemption is given.
