News Releases

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.

Calgary, Alberta, September 28, 2023: High Arctic Energy Services Inc. (TSX: HWO) “High Arctic” or the “Corporation” provides an update on the contemplated reorganization of the Corporation, including the associated tax efficient $38.2 million return of capital, the Papua New Guinea focused business spin-out to shareholders, refocus of the Canadian business and an update on its Papua New Guinea (“PNG”) operations. The Corporation has received feedback from shareholders and is working with its advisors on the reorganization plan to incorporate key elements of the shareholder feedback. The High Arctic board has reserved its final decision to proceed with the reorganization until these matters and ongoing strategic review have been addressed to their satisfaction, requisite regulatory approvals have been received, and the materials are ready to present to shareholders. The Corporation cautions readers that there is no certainty that the reorganization will proceed in the format previously announced, or at all. In PNG, Rig 103 has continued to operate reliably since returning to work and in the process our crews have passed through 7 years and 3.5 million work hours of recordable incident free operations. Activity is nearing the halfway point of the four currently committed wells for our primary customer, under the three-year operations and management contracts that mature in August 2025. High Arctic observes that the Papua-LNG partners have pushed back guidance for the target final investment decision on the project website https://papualng.com.pg/ to “early 2024”. We have also observed that the project planning involves the creation of road access to the development well sites and as a result will likely not specifically require heli-portable drilling rigs. High Arctic was involved in drilling four of the Antelope field appraisal wells with our heli-portable drilling rigs. While High Arctic has specialist PNG drilling knowledge that we strongly believe is critical to successful well delivery, there is no guarantee that our rigs will be deemed suitable for, or that we will be contracted to conduct the Papua-LNG development drilling at the Elk / Antelope fields.
