News Releases

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 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 haes.ca.

CALGARY, Canada – November 12, 2021 – High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) released its’ third quarter results today. Mike Maguire, Chief Executive Officer, commented: “The market and High Arctic have reached an inflection point. Commodity prices have increased significantly, a rig is being mobilized to location in Papua New Guinea, operating hours are increasing in Canada and many customers are receptive to pricing discussions. The past 18 months have been exceptionally challenging as we dealt with the impact of the Covid-19 pandemic and an oil price collapse. I want to thank our employees and shareholders for being supportive through this difficult period. We are implementing initiatives to reward our loyal employees, attract new staff and continue to provide high quality services to our clients in this period of renewed opportunity. The recent $0.20 special dividend underscores the confidence of board and management in the significantly improving market conditions and our business fundamentals..” HIGHLIGHTS • PNG continues to be a strategic investment for the Corporation. During Q3-2021 we began mobilizing equipment and personnel within our drilling services segment and expect to commence wellsite activity in the latter half of Q4-2021. In the process, we extended recordable incident free activity in PNG out to 5 years and over 2.5 million work hours. • Growth in High Arctic’s Canadian production services and ancillary services were assisted by operating rate improvements but hindered by Covid-19 outbreaks in August and September and soft utilization in one of our main well servicing contracts. High Arctic has subsequently enacted a Covid vaccination or negative-test requirement to ensure the employee is safe to work. Despite a difficult quarter, our well servicing utilization of 41% remained above the industry average of 38%. • Consolidated Q3-2021 revenues were $18.7 million ($18.5 million in Q3-2020). The Corporation generated EBITDA of $1.3 million and $3.3 million during Q3-2021 and YTD-2021, respectively. • Cost reduction initiatives undertaken in 2020 delivered $2.7 million or 26.6% lower general and administrative costs during the first nine months of 2021. • In October of 2021, the Corporation announced a special one-time dividend payment of $0.20 per share to holders of common shares and paid dividends of $9.7 million on November 5, 2021. The dividend emphasizes High Arctic’s strong balance sheet position and ability to return surplus cash to shareholders. Post dividend, the Corporation has a substantive net cash balance and with improving EBITDA, increasing access to funds under a $45 million loan facility to fund growth initiatives. The Corporation’s strategic priorities for 2021 include: • Safety excellence and focus on quality service delivery through consistent global standards; • Cost control focused on operating cash flow, while balancing strategic priorities to fuel growth; • Investment initiatives that secure the Corporation’s future as a lower emissions energy services provider; • Growth and divestiture opportunities that enhance shareholder value, align with our core service offerings, and reside in well understood markets; and • Disciplined working capital management and capital stewardship to improve returns for shareholders that potentially include dividends and common share buybacks. ——————– Nov 12 2021 – Q3 Press Release

High Arctic Announces 2021 First Quarter Financial and Operating Results  CALGARY, Canada – May 13, 2021 – High Arctic Energy Services Inc. (TSX: HWO) (the “Corporation” or “High Arctic”) released its’ first quarter results today. Mike Maguire, Chief Executive Officer commented: “We navigated the difficult past twelve months with a keen focus on safe and effective operations and maintaining our reputation for superior quality service. High Arctic is emerging from the global crisis with a strong balance sheet and is positioned well to ride the improved market conditions in 2021.  With oil and gas prices having sustained a return to pre-pandemic levels, our customer base is considering opportunities to expand their business activities. Sequential quarterly increases in utilization of our services in Canada has been achieved and I believe we are well placed for high growth in a significantly stronger Canadian market.   In PNG a Covid-19 spike put a stop to almost all activities during the quarter, resulting in a short-term drain on our earnings as we continued to maintain operational readiness.  We expect to benefit from this readiness later in 2021 as government and industry covid-19 prevention strategies take hold, travel restrictions are lessoned and business activities increase. In addition, the Papua LNG partners recently announced remobilization to complete project pre-feed which is a key step on the pathway to a final investment decision.  I believe that our commitment to PNG will, in time, provide significant upside for our shareholders.” HIGHLIGHTS The following highlights the Corporation’s results for Q1-2021: First quarter revenue of $17.8 million, EBITDA of $1.2 million, compared to $39.6 million and $5.5 million respectively in Q1-2020 and a slight improvement over Q4-2020 with $16.6 million and $0.7 million respectively. Total Energies SA recently announced its intention to remobilize teams and resources needed to proceed with development of the Papua LNG project. Balance sheet and liquidity remains strong with cash of $21.0 million, no long-term debt and liquidity that includes an undrawn $45.0 million revolving loan facility. Patent pending on a new low emission electric service rig design. The Corporation’s strategic priorities for 2021 include: Safety excellence and focus on quality service delivery through consistent global standards; Cost control focused on operating cash flow, while balancing strategic priorities to fuel growth; The pursuit of opportunities that secure the Corporation’s future as a lower emissions energy services provider; Growth and divestiture opportunities that enhance shareholder value, align with our core service offerings, and are located in well understood markets; and Disciplined working capital management and capital stewardship to improve returns for shareholders that potentially include dividends and common share buybacks. For more than a year High Arctic has been internally progressing work on a practical process to convert existing Concord well servicing rigs to a reliable, efficient and inexpensive electric drive.  We are pleased to announce that patent is pending on the design and we plan to identify industry partners to further test the technology at a pilot site in 2021.  We see tremendous opportunity for the deployment of this technology in Western Canada, particularly in thermal well applications where existing supply of electrical power of adequate capacity is already available.  Crucially at this stage of development the upgraded service rig maintains its ability to self-propel down the highway.  The upgrade is estimated to reduce the Co2 emissions of a well service rig over the well-bore by more than 35% compared to current diesel-powered rigs. ——————– The unaudited interim consolidated financial statements (“Financial Statements”) and management discussion & analysis (“MD&A”) for the quarter ended March 31, 2021 will be available on SEDAR at www.sedar.com, and on High Arctic’s website at haes.ca.
