High Arctic Announces 2021 Fourth Quarter and Year End Financial and Operating Results

CALGARY, Canada – March 10, 2022, 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, 2021 will be available on SEDAR at www.sedar.com, and on High Arctic’s website at www.haes.ca. Non-IFRS measures, such as EBITDA, Adjusted EBITDA, Adjusted Net Earnings (Loss), Operating margin % and working capital are included in this News Release. See Non-IFRS Measures section below. All amounts are denominated in Canadian dollars (“CAD”), unless otherwise indicated. Mike Maguire, Chief Executive Officer commented: “High Arctic closed out the 2021 fiscal year in excellent position. As underlying business fundamentals began to improve, surplus pre-pandemic cash of $9.7 million was paid to shareholders in the form of a special one-time dividend. We exited the year with a net cash position of $4.0 million, strengthened capital structure with fixed rate mortgage financing and an undrawn revolving credit facility, and increasing revenue fueled by positive pricing trends and the return to work in PNG. Entering 2022, global events have propelled the energy sector into significant supply constraint. Sanctions against Russia combined with the actions of global energy and transport corporations have removed substantial supply of both oil and gas, stressing the market at a time of increasing energy demand as Covid-19 restrictions are lifted. As a result, commodity price strength coupled with long-term security of supply assurances are expected to drive further increases in service activity. More Canadian oil is needed to supply foreign markets, and LNG is increasingly becoming the mobile, low emissions energy source of choice through this period of energy transition. The signing of the P’nyang gas agreement and the progression of the Papua LNG project towards FID, positions Papua New Guinea as a key source of new LNG supply to Asia and the sub-continent. High Arctic is ideally placed to benefit in both of these markets, and as a result we have undertaken to reinstate a regular monthly dividend.” Highlights The following highlights the Corporations results for Q4-2021 and YTD-2021: • High Arctic’s revenues increased 43% to $23.6 million in Q4-2021 relative to Q4-2020 and were 27% higher than Q3-2021, buoyed by renewed activity in the Drilling Services Segment during the quarter. In contrast, YTD-2021 revenues of $76.4 million were lower by 16% primarily due to significantly lower drilling services activity throughout 2021-year compared to the 2020-year which included a full quarter of pre-pandemic activity. • High Arctic’s oilfield services operating margin as a percentage of revenue was 19.9% in both Q4-2021 and YTD-2021, compared to 23% and 23.5% in the corresponding 2020-periods. • High Arctic achieved positive EBITDA of $1.2 million and $4.4 million for Q4-2021 and YTD-2021, while the net loss in the respective 2021-periods was $4.6 million and $18.6 million. • High Arctic returned value to shareholders through a $9.7 million special one-time cash dividend in Q4-2021 while maintaining a strong working capital balance of $29.7 million on December 31, 2021. At year end, High Arctic carried a cash balance of $12.0 million. • Cost reduction initiatives delivered $2.5 million or 19.4% lower general and administrative costs YTD-2021 over prior year, and $5.5 million lower than pre-pandemic YTD-2019 costs. • In December 2021, High Arctic completed a $8.1 million mortgage financing of Corporation owned and occupied land and buildings with an initial 5-year term and a fixed interest rate of 4.30%. Strategy Our 2022 Strategic Priorities build on the platform we created in 2021 and include: • Safety excellence and quality service delivery, • Actions aimed at generating free cash flow including: o Increased utilization of the Corporation’s world-class fleet of equipment, o Improved efficiency and work force productivity, and o Operating cost control, • Development of new and existing employees to grow our workforce to meet demand, • Pursuit of opportunities that secure the Corporation’s future as a lower emissions energy services provider, • Pursuit of opportunities for growth and corporate transactions in well understood markets that enhance shareholder value, and • Disciplined capital stewardship to improve returns for shareholders including dividends and common share buybacks. ——————– The audited consolidated financial statements (“Financial Statements”) and management discussion & analysis (“MD&A”) for the year ended December 31, 2021 will be available on SEDAR at www.sedar.com, and on High Arctic’s website at www.haes.ca.

High Arctic Commences Rig Operations in PNG

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.
