2025

CALGARY, Alberta – November 7, 2025, High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) released its third quarter 2025 financial and operating results. The unaudited condensed interim consolidated financial statements, and the management discussion & analysis (“MD&A”), for the three and nine months ended September 30, 2025 will be available on SEDAR+ at www.sedarplus.ca, and on High Arctic’s website at www.haes.ca. All amounts are denominated in thousands of Canadian dollars (“CAD”), unless otherwise indicated. Lonn Bate, Interim Chief Executive Officer commented: “High Arctic is pleased to have delivered Q3 financial and operational results, driven by strong execution across a number of our 2025 strategic objectives. Q3 2025 results benefited from the provision of significant high-pressure stimulation work for a new customer which contributed to top-line growth and margin expansion. Improved financial performance was achieved as producers continued to deploy capital in developing their Duvernay assets while overall industry activity levels have softened compared to 2024. Our current service offerings and facility locations uniquely position us to provide our customers with the assets they need while allowing us to maintain a high-level of customer service. Additionally, Team Snubbing, of which High Arctic maintains a 42% equity interest, achieved a step-change in financial performance following a key contract award in Alaska and increased activity levels in their Canadian business, resulting in a record quarter for them in terms of revenue and net income. With the senior management changes announced in the quarter, High Arctic has enhanced our leadership capacity with dedicated Canadian management enabling us to further focus on the execution of the Corporation’s strategic initiatives.” In the following, the three months ended September 30, 2025 may be referred to as the “quarter” or “Q3 2025” and the comparative three months ended September 30, 2024 may be referred to as “Q3 2024”. References to other quarters may be presented as “QX 20XX” with X/XX being the quarter/year to which the commentary relates. Additionally, the nine months ended September 30, 2025 maybe referred to as “YTD” or “YTD-2025”. References to other nine-month periods ended September 30 may be presented as “YTD-20XX” with XX being the year to which the nine-month period ended September 30 commentary relates. 2025 Q3 Highlights  Revenue from continuing operations of $2,930, an increase of 17% compared to Q3 2024.  Increased oilfield services operating margin percentage for Q3 2025 to 54.4% compared to 51.5% in Q3 2024.  Realized Adjusted EBITDA from continuing operations of $757 in the quarter, 26% of Q3 2025 revenue and a 98% increase from Q3 2024 Adjusted EBITDA.  Maintained a strong track record of operational excellence and safety, as evidenced by the continuation of recordable incident-free work.  High Arctic’s 42% equity share of Team Snubbing’s net income for Q3 2025 was $756, significantly higher than the $105 recognized in Q3 2024. Team Snubbing continues to benefit from an increase in customer activity, particularly in its operations in Alaska.  Maintained strong financial liquidity throughout the current year quarter, exiting Q3 2025 with positive working capital of $4,183, inclusive of cash of $3,052. Revenue from continuing operations of $7,656, a decrease of 5% compared to YTD-2024.  Achieved an increase in oilfield services operating margin percentage for YTD-2025 of 52.4% compared to 48.8% for YTD-2024.  Realized Adjusted EBITDA from continuing operations of $1,743 for YTD-2025, 23% of YTD-2025 revenue and a 163% increase from YTD-2024 Adjusted EBITDA.  Maintained operational excellence and safety, as evidenced by the continuation of recordable incident-free work.  Achieved expected improvements in general and administrative expenses, a reduction of 44% compared to the YTD-2024 period.  High Arctic’s share of Team Snubbing’s net income for YTD-2025 was $420 compared to a net loss of $294 for YTD-2024. 2025 Strategic Objectives The Corporation’s 2025 strategic objectives, which are unchanged from Q2 2025, include:  Relentless focus on safety excellence and quality service delivery;  Grow the core businesses through selective and opportunistic investments;  Actively manage direct operating costs and general and administrative costs;  Steward capital to preserve balance sheet strength and financial flexibility; and  Execute on accretive acquisitions or strategic alternatives in Canada to drive shareholder value. Outlook The third quarter of 2025 was a very busy and positive quarter for High Arctic. The tactical equipment additions made in 2025 to the rentals business enabled the business to secure and provide high-pressure stimulation assets to a new customer active in increasing their Duvernay production levels that drove higher year over year revenues and margins for the quarter. Additionally, Team Snubbing saw activity in both Canada and the US pick up as work that was deferred in Canada earlier in the year resumed and recent contract awards in the US saw a snubbing package go back to work for the majority of the quarter. Although High Arctic’s revenues, Adjusted EBITDA and liquidity position are not directly impacted by the results of Team Snubbing because of its minority equity ownership, the management of the liquidity/capitalization of Team Snubbing, including its debt leverage levels continue to be a top priority for High Arctic. Finally, the senior management changes that were made in the quarter resulted in the full separation from High Arctic Overseas Holdings Corp. following the Arrangement, allowing management to focus on the execution of Corporation’s strategic objectives. High Arctic’s business is driven by the underlying economics associated with its customers’ cash flows. These cash flows are driven by their oil and natural gas commodity price hedging and expectations. As customers embark on drilling new oil and natural gas wells, High Arctic’s business outlook is reliant on decisions on the subsequent activity to complete these wells for production. Therefore, the financial and operational performance of High Arctic’s rental assets and investment in the snubbing industry are highly dependent on fundamentals associated with both drilling and hydraulic fracturing completion trends in the western Canadian sedimentary basin. As the industry enters the final quarter of 2025, activity and well licensing have softened when … Read more
