North American Construction Group Closes Strategic Acquisition of Iron Mine Contracting, a Diversified Mining Services Contractor

ACHESON, Alberta, April 07, 2026 (GLOBE NEWSWIRE) -- North American Construction Group Ltd. ("NACG" or the "Company") (TSX:NOA) today announced the closing of its acquisition of Iron Mine Contracting ("IMC"), with a closing date of April 7, 2026 and an economic effective date of January 1, 2026 (the "Transaction"). Total expected consideration is approximately $125 million (the "Consideration"), with the final Consideration amount to be determined based on IMC's financial statements as of December 31, 2025, which will be reflected in the Company's financial statements for the quarter ended June 30, 2026.

IMC provides NACG with an established operating platform in Western Australia, including a diversified, blue-chip customer base and exposure to gold, iron ore and lithium, further aligning the Company with structural demand tied to rare earth and critical minerals. The combination of IMC with NACG's existing MacKellar operations is expected to enhance scale and deepen local expertise while establishing a Tier 1 platform in the overall Australian market.

Since the Transaction was announced on December 18, 2025, IMC has progressed well in its growth plans with increasing scopes at key mine sites. Notably, scopes commenced as expected late in the first quarter of 2026 at a gold-copper mine in the Pilbara region.

Amended Credit Facility and Prudent Transaction Funding Structure

Concurrent with closing the Transaction, the Company amended its senior secured credit facility (the "Credit Facility") with direct lending capacity of $535 million provided by Canadian dollar and Australian dollar tranches. The facility also permits incurrence of $500 million of secured equipment financing from third party providers resulting in total senior secured capacity of over $1.0 billion. For reference, continued access to the bond market further enhances liquidity capacity. As part of the amendment, the maturity date of the Credit Facility was further extended to April 7, 2029. The Credit Facility remains comprised of a revolver with no scheduled repayments. Financial covenants are consistent with the previous agreement and are tested quarterly on a trailing four-quarter basis.

Cash funding for the upfront payment of $41.5 million was provided by draws from the Credit Facility. Equipment financing of approximately $45 million was assumed at closing with remaining Consideration, approximately one-third of the total, being provided by earn-out and deferred payment mechanisms payable to the sellers over four years based on performance of the business.

National Bank Capital Markets is acting as financial advisor to NACG on this Transaction. Fasken Martineau DuMoulin LLP is acting as Canadian legal advisor and MinterEllison is acting as Australian legal advisor to NACG.
