2023

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.

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.

CALGARY, Canada – December 13, 2023 – High Arctic Energy Services Inc. (TSX: HWO) (“High Arctic” or the “Corporation”) is pleased to announce that it has made the necessary filings and received the necessary approvals to conduct a normal course issuer bid (“NCIB”) through the facilities of the Toronto Stock Exchange (“TSX”). The TSX has accepted the Corporation’s notice to conduct the NCIB to purchase outstanding common shares of the Corporation on the open market, in accordance with the rules of the TSX. As approved by the TSX, the Corporation is authorized to purchase up to 1,000,000 common shares. The Corporation can apply for additional purchases to a maximum amount under the NCIB representing the higher of 10% of the public float and 5% of the issued and outstanding shares of High Arctic. There were 49,122,302 common shares outstanding as of December 5, 2023. The TSX also limits the maximum number of common shares that High Arctic may purchase on any given day to 25% of the average daily trading volume of common shares on the TSX for the six-month period prior to NCIB approval. For the six-month period ended November 30, 2023, the average daily trading volume of High Arctic shares was 18,669 leading to a daily NCIB purchase limit of 4,667 common shares. Subject to prescribed rules, High Arctic may also make one block repurchase in any five-day period which exceeds the daily limit. The Corporation is authorized to make purchases during the period from December 15, 2023 to December 14, 2024, or until such earlier time as the NCIB is completed or is terminated at the option of the Corporation. Any common shares the Corporation purchases under the NCIB will be purchased on the open market through the facilities of the TSX and/or Canadian alternative trading systems, at the prevailing market price at the time of the transaction. The Corporation has appointed an independent brokerage agent to conduct the NCIB transactions under an automatic purchase plan agreement (“APPA”). The APPA will allow the broker to purchase common shares under the bid during internal blackout periods when the Corporation would normally not be permitted to trade in its shares. Such purchases will be at the sole discretion of the broker based on direction received from High Arctic prior to any blackout period and in accordance with all regulatory and securities law. All common shares acquired under the NCIB will be cancelled. The Corporation believes that from time to time the market price of High Arctic common shares may not reflect their underlying value and that, at such times, the purchase of common shares for cancellation will increase the proportionate interest of, and be advantageous to, all remaining shareholders. In addition, the purchases by High Arctic under the NCIB may increase liquidity to the Corporation’s shareholders wishing to sell their common shares. The Corporation’s previous NCIB will expire on December 14, 2023, and under that program, a total of 18,296 common shares at a weighted average price of $1.37 per share were repurchased for cancellation. The Corporation sought and obtained from the TSX approval to purchase 750,000 common shares of the Corporation under the previous NCIB. About High Arctic High Arctic is an energy services provider.

Calgary, Alberta, October 23, 2023: High Arctic Energy Services Inc. (TSX: HWO) “High Arctic” or the “Corporation” updates shareholders on previously announced reorganization, monthly dividend and the timing for its third quarter results. Reorganization The Corporation continues to research an alternative structure that will meet both the goals of strategic business management and governance concerns of shareholders. While the Corporation is optimistic about achieving a reorganization acceptable to shareholders, there is no certainty at this time. Dividend Suspension With the delay in the reorganization, the Corporation believes it is in the best interests of shareholders to preserve cash to maximize the opportunity to tax-efficiently return capital. The Corporation is weighing balance sheet strength in conjunction with the merit of a tax-efficient return of capital distribution up to a maximum of $38.2 million (75 cents per fully diluted share). Accordingly, High Arctic is announcing it is suspending its monthly $0.005 per share dividend effective immediately as the Board of Directors is of the view that continuing the monthly dividend is no longer in the best interest of shareholders. Timing of Third Quarter Results High Arctic intends to release its 2023 third quarter results on Wednesday November 8, 2023 after markets close and has scheduled a conference call to begin at 10:00 am MT (12:00 pm ET) on Thursday, November 9, 2023.
