CALGARY, Alberta – May 15, 2024, High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) released its’ first quarter financial and operating results. The unaudited consolidated financial statements, management discussion & analysis (“MD&A”), for the quarter ended March 31, 2024 will be available on SEDAR+ at www.sedarplus.ca, and on High Arctic’s website at haes.ca. All amounts are denominated in Canadian dollars (“CAD”), unless otherwise indicated. Intention to Return Capital and Reorganize On May 11, 2024 the Corporation announced the Annual General and Special Meeting of Shareholders to be held in Calgary, Alberta on June 17, 2024 (the “Meeting”). The meeting has been called by the High Arctic Board of Directors for the purpose of holding a shareholders vote on the separation of the Corporation’s North American and Papua New Guinea (“PNG”) businesses, by way of a court-approved plan of arrangement (the “Arrangement”), as well as a distribution of surplus cash to shareholders by way of a return of capital of up to $0.76 per common share ( up to $38.2 million) of High Arctic (the “Return of Capital”). The Arrangement will transfer High Arctic’s PNG business to a separate, dedicated, and independent, publicly traded company named High Arctic Overseas Holdings Corp. (“SpinCo”), while High Arctic will continue to own and operate the Corporation’s existing North American Business. Each of the two companies will have its own management and operational teams and a separate Board of Directors. Under the proposed Arrangement, each shareholder of High Arctic will receive one-quarter of one (1/4) common share of SpinCo and one-quarter of one (1/4) common share of post-Arrangement High Arctic for each common share of High Arctic held. As a result of the Arrangement, each shareholder will continue to own its pro rata portion of both SpinCo and post-Arrangement High Arctic. The Arrangement, the Return of Capital, and other resolutions related to the reorganization, as well as annual meeting matters, will be put to the Shareholders for approval at the Meeting. Both the Arrangement and the Return of Capital will require two thirds (2/3) of all votes cast in favour to pass. Mike Maguire, Chief Executive Officer commented: “Our businesses in both Canada and PNG have had very solid starts to 2024. Our recent acquisition and amalgamation of Delta Rental Services in Canada has delivered financial performance in line with our pretransaction expectations and we anticipate further improvement as we move out of integration phase and optimize equipment cross-deployment. In PNG Rig 103 has delivered another high-quality quarter of drilling activity ahead of its suspension and stacking which will be completed in Q2 2024. I am pleased to have finally published the details of our long-anticipated reorganization and the associated tax efficient Return of Capital to shareholders. I am excited about the opportunities that this can unlock for the two distinct and separate businesses. Mail-out of meeting materials to shareholders is underway and I encourage all shareholders to read the materials which detail the reasons supporting the Arrangement, key dates and the processes available for voting. The PNG business will be owned by a new publicly listed Canadian company with operations focussed on PNG. High Arctic will retain the Canadian assets which have been strengthened with the addition of Delta Rental Services and is an attractive vehicle for future growth and transactions. The Board and Management of High Arctic unanimously recommend that all shareholders vote in favour of all resolutions at the meeting.” In the following discussion, the three months ended March 31, 2024 may be referred to as the “quarter” or “Q1 2024” and the comparative three months ended March 31, 2023 may be referred to as “Q1 2023”.

CALGARY, Canada – May 11, 2024 – High Arctic Energy Services Inc. (TSX: HWO) (“High Arctic” or the “Corporation”) is pleased to announce that its Board of Directors (“Board”) has unanimously approved the reorganization of High Arctic to separate the Corporation’s North American and Papua New Guinea (“PNG”) businesses, by way of a court-approved plan of arrangement (the “Arrangement”), as well as a distribution of surplus cash to shareholders by way of a return of capital of up to $38.2 million (up to $0.76 per common share) of High Arctic (the “Return of Capital”). The Arrangement will transfer High Arctic’s PNG business to a separate, dedicated, and independent, publicly traded company named “High Arctic Overseas Holdings Corp.” (“SpinCo”), while High Arctic will continue to own and operate the Corporation’s existing North American Business. Each of the two companies will have its own management and operational teams and separate Board of Directors. Under the proposed Arrangement, each shareholder of High Arctic (“Shareholder”) will receive one-quarter of one (1/4) common share of SpinCo (“SpinCo Common Share”) and one-quarter of one (1/4) common share of post-Arrangement High Arctic for each common share of High Arctic held. The Arrangement, the Return of Capital, and other resolutions related to the reorganization, as well as annual meeting matters, will be put to the Shareholders for approval at an annual general and special meeting of shareholders of the Corporation to be held in Calgary, Alberta on June 17, 2024 (the “Meeting”). As a result of the Arrangement, each Shareholder will continue to own its pro rata portion of both SpinCo and post-Arrangement High Arctic. Strategic Rationale High Arctic’s Board and management are of the view that the Corporation has historically been unable to derive appropriate value from the market that represents the sum of the parts. The Corporation has also found a lack of synergy between the businesses in PNG and Canada. In separating the PNG business from the Corporation, High Arctic’s Board and management believe value can be created for the Shareholders. For the holders of SpinCo Common Shares, separation provides the opportunity for SpinCo to consider transactions with a wider group of PNG focused companies, and greater flexibility to relocate in the future to a market that better understands PNG and is likely to ascribe greater value to SpinCo. For the holders of post-Arrangement High Arctic common shares, the transaction opens-up opportunities for High Arctic to participate in Canadian M&A activity where the PNG business may have been perceived as an impediment to accretive transactions. For years the Corporation has both pursued or entertained potential business combination transactions. The distinctly different profiles of the North American and PNG businesses have proven to be the main impediment to identifying transactions acceptable to all parties and in the best interests of Shareholders. Finding unique companies desirous of being linked to both distinct businesses has proven unsuccessful. Companies to whom association with our North American Business may be attractive are a distinctly broader group and do not overlap with the international companies with whom the PNG business and its risk profile may fit well. Board and management unanimously agree that the separation of these two businesses will ensure that management is dedicated to enhancing the value of each business and accessing new pathways to transformative and accretive transactions that are currently inaccessible.   Benefits to Shareholders Certain of the expected benefits to Shareholders of the Arrangement are as follows:  The benefits of dividing the Corporation into its distinct businesses;  Each company will be owned by Shareholders on a pro rata basis with reference to the number of High Arctic Common Shares held prior to the Arrangement;  The Arrangement is expected to improve the market’s identification and valuation of each company and allow Shareholders, investors and analysts to more accurately compare, evaluate and value each of the companies on a stand-alone basis against appropriate peers, benchmarks and performance criteria specific to that company;  Each company will have independent access to capital (equity and debt) which management believes will result in optimal capital allocation;  The procedures by which the Arrangement is to be approved, including the requirement for approval of the Arrangement by the Court after a hearing at which fairness to the Corporation’s securityholders will be considered;  The Corporation has received the financial Fairness Opinion (defined below);  The availability of rights of dissent to Shareholders with respect to the Arrangement; and  The tax treatment of the Arrangement is expected to be tax efficient for Canadian tax purposes for most shareholders. Board and Management of High Arctic and SpinCo The Hon. Joe Oliver has informed the Corporation that he does not intend to stand for re-election as a director at the Meeting and will resign on May 15, 2024. Mr. Oliver has served as a director of High Arctic for eight years, and his intention to resign coincides with the Arrangement and the setting of a new strategic direction for the remaining Corporation, which he supports. Michael Binnion, High Arctic’s Chairman stated: “On behalf of the Board, I would like to thank the Honorable Joe Oliver for his dedication and commitment to High Arctic during his tenure. Joe has played an important role in the evolution of High Arctic including the challenges of a global pandemic and a rebuilding of the businesses that sets the stage for a new and independent future. We wish Joe all the very best.” Upon completion of the Arrangement and election or re-election by Shareholders at the Meeting, the Board of High Arctic will consist of: Simon Batcup (Chair) Douglas Strong Michael Binnion Craig Nieboer The management of High Arctic will consist of: Michael Maguire (Interim CEO) Lonn Bate (CFO) Trevor Barker (GM Operations) Justin Morrical (Business Development Manager) High Arctic is actively pursuing permanent CEO placement options. If the Arrangement is approved, Mr. Maguire will assume the role in an interim capacity and transition duties to a new CEO appointed by the Board. The management … Read more

CALGARY, Canada – April 8, 2024, High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) released its’ fourth quarter and year-end results today. The audited consolidated financial statements, management discussion & analysis (“MD&A”), and annual information form for the year ended December 31, 2023 will be available on SEDAR at www.sedar.com, and on High Arctic’s website at haes.ca. All amounts are denominated in Canadian dollars (“CAD”), unless otherwise indicated. The Corporation provided an update today on the intention to issue shareholders a tax efficient return of capital to a maximum of $38.2 million and plan to reorganize the Corporation at a special meeting of the Shareholders. The recommendation to reorganize is expected to include the following elements: – a spinoff of the international business to shareholders as a Canadian publicly listed company, – maintaining the Corporation as a Canadian publicly listed company focused on growing the Canadian business, – distribution of a return of capital to shareholders of between $33.0 million and $38.2 million before July 26, 2024, and – right-sizing the general and administrative infrastructure to align with the new corporate structure. The Corporation is working with DLA Piper (Canada) LLP as legal advisor and Lightyear Capital Inc. as financial advisor on the revised reorganization plan. The completion of which will be subject to Board, stock exchange, applicable regulatory and shareholder approval at a special meeting of the Shareholders to be held before the end of June 2024. Mike Maguire, Chief Executive Officer commented: “Our businesses in both Canada and PNG have finished the year with a solid quarter and we made an exciting acquisition with the purchase and amalgamation of Delta Rental Services in Canada. Following the receipt of feedback from our shareholders and consultation with our advisors, I am excited to provide today’s update on the path the Board intends to take in order to reorganize the Corporation and release a tax-efficient return of cash to shareholders. The proposed spin-off of the Papua New Guinean business as a publicly listed Canadian company will allow senior management to concentrate where we have had the most success in the past. The remaining publicly listed company with the Canadian assets has been further strengthened with the addition of Delta Rental Services and becomes an attractive vehicle for future growth and transactions. I continue to believe our customers and employees in both PNG and Canada will appreciate and benefit from locally managed businesses.” Expectations that Rig 103 drilling activity will be concluded by the end of June 2024 have been confirmed with the receipt of formal notice from High Arctic’s principal customer in PNG of its intention to suspend drilling operations and cold stack Rig 103 at the conclusion of this final approved well on the Rig 103 drilling schedule. The Corporation remains engaged with its principal customer on planning for 2025 drilling activity. Further, the PNG Government and Papua- LNG operator TotalEnergies have released a joint statement advising that the FID of the Papua-LNG project is now expected in 2025. In the following discussion, the three months ended December 31, 2023 may be referred to as the “Quarter” or “Q4 2023”, and similarly the year ended December 31, 2022 may be referred to as “YTD 2022”.

References to other quarters may be presented as “QX 20XX” with X being the quarter/year to which the commentary relates. 2023 Highlights The following highlights the Corporations results for Q4 2023 and YTD 2023: – Acquired Delta late in Q4 2023 which expanded High Arctic’s geographical coverage in Alberta and offers both operational synergies and potential for cross deployment of underutilized assets in the Canadian rentals business. – Realized a third continuous quarter of full utilization of PNG Rig 103 in Q4 2023, pursuant to a 3-year contract that was renewed in 2022. – Improved liquidity with a working capital balance of $63.0 million, which includes a cash balance of $50.3 million, and long-term debt of $3.5 million. – Generated Adjusted EBITDA from continuing operations of $11.8 million in FY 2023 and $3.2 million in Q4 2023. – Realized a net loss from continuing operations of $12.8 million in FY 2023 and net income from continuing operations of $2.7 million in Q4 2023.

CALGARY, Alberta – December 28, 2023, High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) announces that today it has closed the acquisition of Delta Rental Services Ltd. (“Delta”) for aggregate purchase consideration of $7 million subject to earn-out provisions, pursuant to a Share Purchase Agreement between High Arctic and the shareholders of Delta (the “Delta Acquisition”). Delta is a privately owned rentals company headquartered in Red Deer, Alberta, Canada, founded in 2016. Delta’s business is focussed on pressure control equipment and equipment supporting the highpressure stimulation of oil and gas wells, along with other well site rental equipment. Delta supports a range of customers including top-tier multi-national and domestic energy producers and their contractors. The Delta Acquisition includes all of the assets, personnel and contracts of Delta including the retention of their current yard and office lease in Red Deer. The consideration includes $3.43 million in cash paid at closing with the remaining $3.57 million payable as 75% in cash and 25% in High Arctic common shares to the selling shareholders as an earn-out over three years, subject to achieving certain financial performance targets. Each annual earn-out payment is adjusted up or down depending upon the amount of over or under performance of the Delta business to the targets. Issuance of the common shares pursuant to the earn-out would be subject to regulatory approvals including the approval of the Toronto Stock Exchange (“TSX”). In its most recently completed financial year, Delta recorded over $8 million in revenue at margins consistent with High Arctic’s Canadian business. The total consideration represents a 3 – 3.5x multiple of the Corporation’s estimated annual after-tax cash flow contribution from Delta. Mike Maguire, CEO of High Arctic, said “Delta is an important strategic development for High Arctic. We are excited to be bringing co-founder Mr. JD Morrical and the Delta team into High Arctic. The Delta brand is a strong one synonymous with quality and service. The combination of Delta and High Arctic expands geographical coverage in Alberta and offers both operational synergies and potential for cross deployment of underutilized assets. I am confident the combined HAES Rentals and Delta team will deliver performance greater than the sum of its parts.” “The Delta Acquisition addresses strategic objectives of scaling our Canadian business and pursuing opportunities for growth that enhance shareholder value. The Delta Acquisition is expected to increase Canadian revenues three to four-fold and contribute strongly to positive cash flow. The Delta Acquisition contemplates, and the structure of the consideration is reflective of, High Arctic’s intention to reorganize and separate the Canadian and PNG businesses and maximize a return of capital to shareholders. I am confident that this transaction is symbolic of the prospects for a purely Canadian entity and how additional accretive transactions can be unearthed.” JD Morrical, President of Delta, said “I am keen to start the next part of the Delta story as a substantive part of High Arctic’s Canadian business. We have enjoyed a good relationship with the HAES Rentals team built on mutual respect and shared values. I am very happy that the small business that Scott Odegard and I created has grown to the point that High Arctic wants us to be part of their group. It also represents a cash realization as we honor Scott, his family, and transition the business with his passing in 2021. I am thankful for the support of our loyal customers and staff who are more like family to us, and I am glad that they will all become part of the High Arctic team. I look forward to playing a key leadership role in forging these two rentals businesses together and continuing their growth.” Non-GAAP Measures High Arctic uses certain performance measures that are not recognizable under International Financial Reporting Standards (“IFRS”). These performance measures include cash flow and after-tax cash flow. Management believes that this measure provides supplemental financial information that is useful in the evaluation of High Arctic’s operations. Readers should be cautioned, however, that these measures should not be construed as alternatives to measures determined in accordance with IFRS as an indicator of High Arctic’s performance. The Corporation’s method of calculating these measures may differ from that of other organizations and, accordingly, these may not be comparable.
