Our current service offerings and facility locations position us to provide our customers with the assets they need while allowing us to maintain an exceptional level of customer service. Team Snubbing, in which High Arctic holds a 42% non-operating equity interest, continued its strong operational momentum on Alaska’s North Slope and delivered record net income during the quarter. These results significantly exceeded any prior second-quarter performance since Team Snubbing acquired the snubbing assets from High Arctic in 2022. Team continues to build relationships with existing and prospective customers across Alaska and is pursuing international opportunities that could provide meaningful growth in the second half of 2026 and beyond. These achievements validate Team Snubbing’s growth strategy and the strength of its services offerings. With increasing scale, a growing opportunity set, and a proven operating track record, they are well positioned to continue generating profitable growth and creating long-term value High Arctic. As always, we remain committed to delivering our high standard of customer service with a relentless focus on safety, service quality, and continued cost management across the business.” Highlights • Revenue increased with planned customer well completions, enabled by first half weighed capital expenditure program; • Customer relationships strengthened with Q2 2026 operational execution; • Profit margin percentage compressed due to mix of rental services and increased Q1 2026 equipment maintenance costs; • Significant net income turnaround from 42% equity investment in Team Snubbing, an increase of $1.15 million over YTD-2025; • G&A expenses increased $0.15 million over YTD-2025 with appointment of full-time Interim CEO last August, and professional fees, and • Liquidity of $4.4 million, comprised of $3.0 million cash and cash equivalents and undrawn bank facility. Second Quarter 2026 Summary • Revenue of $2,941 for Q2 2026 increased by $550 or 23% compared to Q2 2025. The increase in revenue is attributable to improved customer demand and stable pricing for our rental service offerings. • High Arctic generated oilfield services operating margin of $1,302 for Q2 2026 with a corresponding operating margin percentage of 46.2% compared to $1,126 and 49.1% for the prior year comparative quarter. Operating margin was impacted by higher revenues as noted, offset by the reduction in operating margin percentage which was driven by a higher concentration of lower margin well stimulation services. Well stimulation services typically involve a higher labour component, contracted through a third-party. • Adjusted EBITDA for Q2 2026 was $504, or 17% of revenue, compared to the prior year comparative quarter of $482 and 20% of revenue. Adjusted EBITDA was primarily impacted by the same factors impacting oilfield services operating margin as noted above. • Operating loss was $126 in the current year quarter compared to a loss of $254 in Q2 2025. The decrease in operating loss is attributable to the same factors impacting oilfield services operating margin, partially offset by 9% higher general and administrative expenses. • Net income was $3 in Q2 2026 compared to a net loss of $295 in Q2 2025. This increase in net income was a result of the same factors impacting operating income (loss), Team Snubbing’s $456 stronger performance in Q2 2026 versus Q2 2025 offset by the $362 fair value adjustment recorded in Q2 2025 relating to the contingent consideration payable pursuant to the 2023 Delta Services Ltd. (“Delta”) acquisition. • The Corporation maintained operational excellence and safety throughout the quarter as evidenced by the continuation of lost time and recordable incident free work. • High Arctic exited Q2 2026 with net working capital of $4,579, including $3,025 of cash and cash equivalents, an undrawn credit facility and $2,916 in long-term debt. First Half 2026 Summary • YTD revenue of $5,676 increased by $950 or 20% compared to YTD-2025. Consistent with Q2 2026 results, the increase in revenue is attributable to improved customer demand and stable pricing for our rental service offerings. • High Arctic generated oilfield services operating margin of $2,424 for YTD-2026 with a corresponding operating margin percentage of 44.6% compared to $2,313 and 51.1% for the prior year comparative period. Operating margin was impacted by higher revenues as noted above, offset by the reduction in operating margin percentage which was driven by a higher concentration of lower margin well stimulation services combined with an increase in equipment repairs and maintenance expense. • Adjusted EBITDA for YTD-2026 was $892, or 16% of revenue, compared to the prior year comparative period of $986 and 21% of revenue.

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
