CALGARY, Canada – January 31, 2022 – High Arctic Energy Services Inc. (TSX: HWO) (“High Arctic” or the “Corporation”) is pleased to confirm that it has commenced rig operations in Papua New Guinea (“PNG”) with Rig 115 starting wellbore work activity for one of our primary customers. Following the assembly and recommissioning of Rig 115 and equipment on site, work recently commenced on re-entering the wellbore. This key milestone was achieved without incident, building on the 5 years and 2.5 million hours worked without recording an incident in PNG. The efficient movement of High Arctic people and equipment to the wellsite was hindered by unavailability of transportation equipment, significant weather events and Covid-19 induced personnel shortages and travel restrictions which combined to move the commencement date into 2022. Mike Maguire, CEO noted “The recommencement of rig operations is a key milestone underpinning our strategic investment in PNG. The attainment of this milestone in the face of obstacles presented by complex supply chains and remote environments could not have been achieved without the support of our customer and the unwavering efforts of our highly experienced crews in country and dedicated support personnel. That we have managed to safely overcome these exceptional challenges is a credit to the remarkable people involved. The commencement and rig recommissioning, after a prolonged period of inactivity, we believe is a harbinger of better times ahead. While the current project is of a relatively short duration into the second quarter of 2022, positive energy service momentum in PNG continues to build. PNG’s potential to expand LNG export capacity is of world class scale and High Arctic remains exceptionally well positioned to benefit. In addition to investment parameters, long-term climate benefits for LNG over coal consumption in the Asian region are extremely compelling. To this end, producer and PNG government discussions continue to advance and the Corporation expects key decisions, including execution of the P’nyang Gas Agreement, to be forthcoming.” High Arctic has been active in Papua New Guinea for nearly fifteen years, conducting work for all the main exploration and production companies including large multi-nationals and companies of regional significance. With the successful resumption of drilling services in PNG, the stage is set for meaningful drilling project announcements during 2022. Forward-looking statement advisory Readers are cautioned that this press release contains certain forward-looking information which are subject to particular risks associated with the energy services industry. High Arctic believes there are reasonable grounds for the expectations on which the statements are based. However actual outcomes in PNG could differ materially due to a range of factors including continued safety performance excellence, ongoing relationship with major customers, PNG’s potential to expand LNG export capacity, future use of LNG over coal consumption in the Asian region, an execution of the P’nyang Gas Agreement, meaningful drilling project announcements during 2022, treatment under governmental regulatory regimes, other government issues and approvals, political uncertainty and civil unrest, currency fluctuations, and the impact of COVID-19.

CALGARY, Canada – December 20, 2021 – High Arctic Energy Services Inc. (TSX: HWO) (“High Arctic” or the “Corporation”) is pleased to announce that it has entered into a mortgage arrangement (the “Mortgage Financing”) with Business Development Bank of Canada (“BDC”) secured by land and buildings owned and occupied by High Arctic (the “Mortgage Security”). The Mortgage Financing provides the Corporation with long term liquidity. It supplements the Corporation’s net cash position which was $20.2 million as of September 30, 2021 before taking in to account a special dividend of $9.7 million paid on November 5, 2021. The $8.1 million mortgage has an initial term of 5 years with a fixed interest rate of 4.30% and an amortization period of 25 years. Payments are due monthly, with the option to prepay up to 15 percent in any 12-month period. The mortgage is secured by land and buildings owned by the Corporation and located within Alberta, Canada. The current credit facility with HSBC (the “Credit Facility”) which matures on August 31, 2023, has been amended to accommodate the Mortgage Financing. The availability has been reduced from $45 million to $37 million and site-specific assets held as Mortgage Security for BDC have been carved out. The Credit Facility remains subject to certain EBITDA covenants, however a minimum of $5 million can be drawn outside of these covenants. All other material terms of the Credit Facility remain unchanged. Lance Mierendorf, CFO noted “The mortgage financing strengthens the Corporation’s capital structure by providing a layer of long-term debt positioned to endure the energy services business cycle. The financing adds to existing cash balances and when combined with an undrawn Credit Facility provides strong liquidity. With an improving outlook in both Canada and Papua New Guinea this development strengthens High Arctic’s financial flexibility to meet operational and investment opportunities.” About High Arctic High Arctic’s principal focus is to provide drilling and specialized well completion services, equipment rentals and other services to the oil and gas industry.

CALGARY, Canada – December 13, 2021 – 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 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 2,420,531 common shares, representing approximately 10% of the public float for High Arctic. There were 48,733,145 common shares outstanding as of December 1, 2021. The maximum number of common shares that High Arctic may purchase on any given day is 12,719 common shares, which represents 25% of the average daily trading volume of 50,878 common shares on the TSX for the six-month period ended November 30, 2021. High Arctic may also make one weekly block repurchase which exceeds the daily limit subject to prescribed rules. All common shares acquired under the NCIB will be cancelled. The Corporation is authorized to make purchases during the period from December 15, 2021 to December 14, 2022, or until such earlier time as the NCIB is completed or 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 or alternative Canadian markets, 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”) dated December 13, 2021. 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. The Corporation believes that from time to time the market price of the 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 expired on December 10, 2021, and under that program, a total of 78,804 common shares at a weighted average price of $1.29 per share have been repurchased for cancellation.

(TSX: HWO) (“High Arctic” or the “Corporation”) is pleased to announce that its Board of Directors has approved a special one-time dividend payment of $0.20 per share to holders of common shares. The dividend is payable on November 5, 2021 to holders of High Arctic common shares of record at the close of business on October 27, 2021. The ex-dividend date is October 26, 2021. The dividend is designated as an “eligible dividend” for Canadian Income Tax purposes. With the first quarter 2020 declaration of the Covid-19 Pandemic and emergence of an oil price crisis, the Board of Directors (the “Board”) suspended regular dividends, halted share repurchases and borrowed $10 million on its revolving loan facility to preserve financial strength. Since this time, the Board and management has continuously monitored business conditions and the financial assets of the Corporation. This included workforce and asset preservation while streamlining business processes within a global leadership structure. Improvement led the Corporation to repay the $10 million dollars drawn from the revolving loan facility during the first quarter of 2021. Continuing improvement during 2021 positioned the Corporation to consider the best use of surplus cash carried since 2019. Currently, positive developments position High Arctic to pay a special one-time dividend while preserving a strong capital structure. Notwithstanding continuing Covid-19 Pandemic challenges, these developments include: economic recovery in the Canadian and global economy, a recovery in global demand for energy, sustained high energy prices for oil and natural gas, the annual Canadian “breakup” seasonal activity low having passed, a resurgence in demand for energy services in Canada and High Arctic’s revenue generating activity in Papua New Guinea recommencing. Mike Maguire, Chief Executive Officer, stated: “Having considered other investment options available to us, it is our view that the most appropriate action right now is to return surplus cash to shareholders by way of special dividend. Post dividend the Corporation will still have a substantive cash balance, an undrawn loan facility and with improving EBITDA increasing access to funds under our $45 million loan facility to fund growth initiatives. We continue to prudently explore opportunities to use our assets to increase shareholder value. This is evidenced by our Q3 2021 investment in modern hydraulic catwalks in our Canadian business and an available Normal Course Issuer Bid to repurchase common shares of the Corporation. We will continue to monitor market conditions, the outlook for our business activities, access to funds and the financial assets of the Corporation with a view to optimising the returns to shareholders including consideration of the timing and amount of any prospective return to regular dividend payments.” About High Arctic High Arctic’s principal focus is to provide drilling and specialized well completion services, equipment rentals and other services to the oil and gas industry.
