All amounts are denominated in Canadian dollars (“CAD”), unless otherwise indicated. Mike Maguire, Interim Chief Executive Officer commented on the Corporation’s third quarter 2024 financial and operating results: “I am very pleased that we completed the strategic re-organization of the Corporation in the third quarter, returning a sizeable amount of capital to our shareholders and spinning out the PNG Business to shareholders via High Arctic Overseas Holdings Corp. listed on the TSX Venture Exchange. The acquisition and integration of Delta Rental Services has delivered positive adjusted EBITDA and cash generation. We have commenced cost rationalization, particularly focussed on general and administrative costs along with overhead cost reduction initiatives. Combined with our equity investment in Team Snubbing and owned real estate, High Arctic is positioned as an attractive vehicle for future growth and transactions.” 2024 THIRD QUARTER HIGHLIGHTS  Completed the re-organization of High Arctic including the return of $37.8 million to shareholders and the spinout of the PNG Business as High Arctic Overseas Holdings Corp., independently listed on the TSX Venture Exchange.  Increased revenue from operations from $2.3 million to $8.0 million year to date on a comparative basis as a result of the Delta Acquisition.  Exited Q3 2024 with net positive working capital of $4.9 million and access to $4.1 million of cash at bank.  Reconciled and took action to reduce general and administrative costs, including a sizeable reduction in board cost and director compensation.  Progressed post-reorganization transitional arrangements towards establishing dedicated stand-alone leadership of the Corporation. 2024 THIRD QUARTER RESULTS  Increased revenue from continuing operations by $1,491 or 147% in the quarter when compared to revenue of $1,015 from Q3 2023 as a result of the impact of the Delta Acquisition on the 2024 results.  Generated net income from continuing operations of $125 in the quarter as compared to $498 in Q3 2023. The decrease is primarily due to the 2023 $615 gain on sale of the nitrogen business, $373 lower interest income with the return of capital to shareholders, and $403 lower equity investment income from Team Snubbing in the quarter.  Achieved positive Adjusted EBITDA from continuing operations of $383 in the quarter versus negative Adjusted EBITDA for Q3 2023 of $700.  Production Service’s 42% equity investment share of Team Snubbing Services Inc. (“Team Snubbing”) net income returned to positive earnings of $105 in the quarter compared to a loss of $889 in Q2 2024 and earnings of $508 in the comparative third quarter of 2023. 2024 YEAR TO DATE RESULTS  Similar to the discrete quarter results, High Arctic’s revenue from continuing operations increased 242% to $8,027 compared to revenue of $2,347 achieved in the first nine months of 2023 as a result of the Delta Acquisition on 2024 results.  Generated a net loss from continuing operations of $1,402 in the quarter as compared to $1,208 in Q3 2023. The higher loss, despite an improvement of $1,323 in operating income, is primarily due to the 2023 $615 gain on sale of the nitrogen business, $262 lower interest income with the July 2024 return of capital to shareholders, and $745 lower equity investment income from Team Snubbing in the year-to-date period.  Achieved strong oilfield services operating margins from continuing operations of 50.6% for the nine months in 2024.  Production Service’s 42% equity investment share of Team Snubbing Services Inc. net loss was $294 for the nine months ended September 30, 2024 as compared to positive net income of $451 in the comparative period in 2023. Regional expansion into Alaska has weighed on earnings during the past twelve months.  Cash from operating activities from continuing operations was $487 in the quarter and a use of $42 for the nine months ended September 30, 2024, an improvement for the quarter as compared to the respective prior year comparatives of $172 and $359.  Significantly lowered the use of funds flow from operations from continuing operating activities as the nine months of 2024 generated a use of funds of $46 compared to a use of funds of $957 for the nine months of 2023 driven by strong operational performance from the Delta Acquisition partially offset by the significant additional G&A expenses incurred in 2024 due to the corporate reorganization initiatives. In the above results discussion, the three months ended September 30, 2024 may be referred to as the “quarter” or “Q3 2024” and the comparative three months ended September 30, 2023 may be referred to as “Q3 2023”.

Pursuant to the reorganization of the Corporation, the PNG business was spun out to the current High Arctic shareholders through a new publicly listed entity High Arctic Overseas Holdings Corp. (“SpinCo”) that will trade on the TSX Venture Exchange under the trading symbol HOH. On June 27, 2024, the Corporation received a final order approving the Arrangement from the Alberta Court of King’s Bench, and the Return of Capital was distributed to shareholders on July 17, 2024. On August 1, 2024, the Corporation was able to fulfill the last major condition in the Arrangement which was the receipt of conditional approval from the TSX Venture Exchange to have the SpinCo shares trade on its exchange. All other terms and conditions to the Arrangement were satisfied subsequent to receipt of conditional approval from the TSX Venture Exchange and the Arrangement was completed on August 12, 2024 and the final approval from the TSX and TSX Venture exchange was received on August 14, 2024. The shares of SpinCo are expected to commence trading on the TSX Venture Exchange on or about August 16, 2024. Pursuant to the Arrangement, each shareholder of High Arctic received one-quarter of one (1/4) common share of SpinCo and one-quarter of one (1/4) common share of post-Arrangement High Arctic for each common share of High Arctic held. As a result of the Arrangement, each shareholder continues to own its pro rata portion of both SpinCo and post-Arrangement High Arctic. SpinCo’s now stand-alone PNG business begins with intact senior leadership and management, a new and independent Board of Directors , a separate stock exchange listing, a strong capital structure, no long-term debt and positive working capital of approximately US$19 million, including US$13 million in cash. Mike Maguire, Chief Executive Officer commented: “Our businesses in both Canada and PNG have performed well in the first half of 2024, setting up both High Arctic and SpinCo with strong financial positions for the commencement of trading as independently listed companies. I am very pleased to have completed the strategic re-organization of the Corporation and excited to be on the precipice of a new chapter in the High Arctic story as the two entities commence separate trading later this week. Both High Arctic and SpinCo have no net debt and access to cash at bank to finance budgeted activities and provide a platform for growth for each business to realize its potential and maximize value for their shareholders. In Canada the performance of our rental business in the first half of 2024 is in-line with our pre-transaction expectations following the acquisition and integration of Delta Rental Services. Having a cash positive business, when adjusted for re-organization costs, positions High Arctic as an attractive vehicle for future growth and transactions. In PNG Rig 103 completed services and was stacked at the forward base in the Southern Highlands, as expected. We anticipate a period of modest activity, through our rentals and manpower provision, as we await significant strategic decisions on major project advancement now expected in 2025.” Additional Information Pertaining to the Reorganization The Corporation has received final approval today to list the post-Arrangement common shares of High Arctic (the “New High Arctic Common Shares”) on the Toronto Stock Exchange (“TSX”). The existing common shares are expected to be delisted from the TSX as of the close of business on August 15, 2024.

CALGARY, Alberta – June 28, 2024 – High Arctic Energy Services Inc. (TSX: HWO) (“High Arctic” or the “Corporation”), further to its news release dated May 11, 2024, is pleased to announce the dates for a distribution of $0.76 per share to its shareholders by way of return of capital (the “Return of Capital”), which was approved by shareholders at the annual general and special meeting held on June 17, 2024. The record date for the Return of Capital will be July 9, 2024 and the payment date will be July 17, 2024. The Return of Capital is expected to be generally more tax advantageous to shareholders than a dividend. The Toronto Stock Exchange (the “TSX”) has determined to implement due bill trading for the Return of Capital. A due bill is an entitlement that will attach to each share traded, from the record date for the Return of Capital to the payment date, inclusive. Each due bill will notionally represent the $0.76 distribution that a holder of a common share of High Arctic on the record date is entitled to receive pursuant to the Return of Capital. During the due bill trading period, a seller of shares (who is prospectively entitled to the $0.76 distribution) will also sell to the purchaser the entitlement to the distribution (which is represented by the due bill attached to each share sold). Due bill trading defers the exdistribution date and ensures shareholders are not deprived of the value of the Return of Capital between the record date and the payment date. Key dates for the Return of Capital are:  The record date to determine shareholders entitled to receive the distribution will be July 9, 2024;  Due bill trading will commence on July 9, 2024;  The payment date for the distribution will be July 17, 2024;  The ex-distribution date will be July 18, 2024 (the first trading day after the payment date, so that trades on and after that date will not have due bills attached); and  The redemption date used by CDS will also be July 18, 2024. All of the foregoing dates are subject to the approval of the TSX. The Return of Capital will be funded from the Corporation’s cash balances. In July 2022, the Corporation made a strategic decision to divest certain well servicing assets in Canada for cash proceeds of $38.2 million. As a result of receiving these cash proceeds plus, cash flow generated subsequently through operating, investing and financing activities, the Corporation had positive working capital of approximately $67.6 million, which included a cash balance of approximately $57.0 million as at March 31, 2024. The Corporation expects to close the proposed plan of arrangement (the “Arrangement”) between the Corporation and High Arctic Overseas Holdings Corp., also announced on May 11, 2024, on or about July 31, 2024. For more information on the Arrangement and the Return of Capital, please see the management information circular of the Corporation dated May 9, 2024, available on the Corporation’s SEDAR+ profile at www.sedarplus.ca.
