FORWARD LOOKING INFORMATION

This Annual Report on Form 40-F and the exhibits attached hereto (the “Form 40-F”) contains “forward-looking information” within the meaning of applicable Canadian securities laws and “forward-looking statements” (and together with “forward-looking information”, “FLI”) within the meaning of the US Private Securities Litigation Reform Act of 1995. FLI relates to Management’s expectations about future events, results of operations, and the future performance (both financial and operational) and business prospects of Enerflex. All statements other than statements of historical fact are FLI. FLI may contain, but is not limited to, words such as “anticipate”, “future”, “plan”, “contemplate”, “create”, “continue”, “estimate”, “expect”, “intend”, “propose”, “might”, “may”, “will”, “shall”, “project”, “should”, “could”, “would”, “believe”, “predict”, “forecast”, “pursue”, “potential”, “objective”, or “capable”, or the inverse of such terms or similar expressions suggesting future conditions, events, or expectations. In particular, this Form 40-F includes (without limitation) FLI pertaining to: the ability of the Company to continue to grow its market share in the US Energy Infrastructure business and the strategies to achieve such growth; expectations as to the growth in the Middle East and Africa market and the associated opportunities in Energy Infrastructure and Engineered Systems, as well as after-market service as a result of such growth and the timing associated therewith; expectations as to the growth in the Latin America market and the associated opportunities for Enerflex to expand product offerings; the Company being optimally positioned to serve client partners in key markets, enhancing long-term shareholder value through sustainable improvements in efficiency, profitability, and cash flow generation; expectations regarding the Energy Infrastructure and After-Market Service product lines and Enerflex’s ability to continue building an increasingly resilient and sustainable business, including by stabilizing cash flows over the long term and reducing cyclicality in the business; a growing liquified natural gas export industry in North America and the ability of the Company to benefit from such growth; expectations regarding the USA market continuing to provide the Company with opportunities to supply compression, processing, low-carbon and electric power solutions; expectations regarding anticipated increases in gas egress capacity in Canada yielding opportunities for Enerflex’s Engineered Systems business; expectations that investments in long-term infrastructure assets will grow the recurring nature of Enerflex’s business; the Company’s backlog and the ability of the Company to convert such backlog into revenue within a reasonable time frame; the ability of the Company to continue to build strong relationships with suppliers; expectations that no aspect of the Company’s business will be materially affected by renegotiation or termination of contracts or sub-contracts; expectations that global energy demand will continue to outpace supply from new renewable capacity and that natural gas will play a critical role in the ongoing energy transition; expectations that substantially all existing and future Energy Infrastructure contracts will be extended or renewed beyond their initial terms or renewed on substantially the same commercial terms; expectations regarding compliance with existing and future laws and regulations; expectations that the Company’s quality management systems, safety systems and local emergency response plans will be effective in reducing the probability of catastrophic events that could impact human health, local communities and/or the environment; risks that new tariffs imposed along with any countervailing tariffs, may adversely affect the demand and/or market price for Enerflex’s products and/or otherwise adversely affect Enerflex; risks that the assumptions, estimates, and analysis impacting Enerflex’s growth projections may not materialize for reasons beyond the Company’s control or at all, and that this may negatively impact the Company’s business, financial condition, results of operations, and cash flow; risks associated with Enerflex’s supply chain and the partial or complete loss of certain suppliers which could result in increased costs and project delays, could have a negative impact on Enerflex’s results of operations, could damage client partner relationships, and could affect Enerflex’s competitive position; risks associated with the ability of the Company to obtain and maintain prudent levels of insurance, and that such coverage will be available on commercially reasonable terms, at levels of risk coverage or policy limits that management deems adequate, or on terms as favourable as Enerflex's current arrangements; expectations that third-party service providers have adequate cyber security measures and that such security measures will prevent any cyber events or computer viruses from impacting the applications upon which Enerflex relies; risks associated with foreign exchange and movement in the Canadian dollar, US dollar, Australian dollar, and Brazilian real and efforts by the Company to hedge all significant transactional currency risks and that such efforts will be successful; the ability of the Company to successfully recover amounts owing in connection with the EH Cryo project; expectations regarding future dividend payments and the ability to continue to pay such dividend; expectations regarding payments to credit rating agencies; expectations as to the timing by which the Company will file its management information circular and hold its annual general meeting of shareholders; and the Company’s belief that the historical information provided by, or derived from information provided by, third parties, is accurate.

FLI is based on assumptions, estimates and analysis made in light of the Company's experience and its perception of trends, current conditions, and expected developments, including assumptions and estimates as to associated timing and costs, as well as other factors that are believed by the Company to be reasonable and relevant in the circumstances. FLI involves known and unknown risks and uncertainties and other factors which are difficult to predict, including, without limitation: the impact of general economic and industry conditions on the Company’s business, including its existing product offerings and the potential for growth and expansion of the business; stock market volatility both generally and specific to the price and liquidity of the Company’s securities; the adoption of new laws and regulations or changes to existing laws and regulations or how they are interpreted and enforced; the adoption of new taxes and tariffs or changes to existing taxes and tariffs and how they are interpreted and enforced; force majeure events; ESG and climate change rules, regulations and policies and the interpretation and enforcement thereof; the Company’s involvement in litigation including with respect to the EH Cryo project; investor sentiment toward the oil and natural gas industry and market trends within the industry; risks inherent in the Company’s supply chain and inventory management; the ability of the Company to hire and retain the personnel critical to its business; the impact to the Company’s business given adverse financial conditions of client partner(s); health, safety, and environment risks and the ability of the Company to manage such risks; increased competition and the ability of the Company to meet competitive pressures within a reasonable cost structure; volatility of oil and natural gas prices; oil and natural gas product supply and demand; future natural gas prices and natural gas exploration and development activity levels; fluctuations in interest rates and foreign exchange rates and risks that the Company’s hedging policy is not able to derisk and offset adverse exchange rate movements; whether the Company is able to develop, adopt, integrate, and deploy new and emerging technologies, and to leverage technological innovations, across its operations, product, and service offerings, to meet evolving customer needs and expectations; regulatory and policy incentives; the ability of the Company to maintain appropriate insurance coverage on commercially reasonable terms and at reasonable prices; risks inherent in conducting international operations, including those related to cultural, political, and economic factors in foreign jurisdictions and to corruption, sanctions, and trade compliance; the ability of the Company to generate sufficient cash flow from operations, and to access credit and capital markets on reasonable commercial terms or at all, to meet its current and future obligations, including the payment of future dividends to shareholders of the Company; the Company and its subsidiaries ability to continue to comply with covenants, financial ratios, and

financial tests applicable under the Revolving Credit Facility; the viability of the Company’s information technology systems or infrastructure; information security and the adequacy of security measures in place at third-parties that provide information technology applications to the Company; the timely and cost-effective execution of projects; the Company’s reliance on contractors and sub-contractors to support project execution and delivery of products and services; and other factors, many of which are beyond the control of the Company. See Enerflex’s Annual Information Form for the year ended December 31, 2024 and in Enerflex’s management’s discussion and analysis for the year ended December 31, 2024, each accessible under the electronic profile of Enerflex on SEDAR+ and Edgar at www.sedarplus.ca and www.sec.gov/edgar, respectively.

Readers are cautioned that the foregoing list of assumptions and risk factors should not be construed as exhaustive. While the Company believes that there is a reasonable basis for the FLI included in this Form 40-F, as a result of known and unknown risks, uncertainties, and other factors, actual results, performance, or achievements could differ materially from those expressed in, or implied by, these statements. Readers are cautioned not to unduly rely on FLI.

TABULAR DISCLOSURE OF CONTRACTUAL OBLIGATIONS

For tabular disclosure of the Company’s contractual obligations, see the Annual MD&A, under the heading “Contractual Obligations, Committed Capital Investment, and Off-Balance Sheet Arrangements”.

COMPARISON OF NYSE CORPORATE GOVERNANCE RULES

The Company is subject to a variety of corporate governance guidelines and requirements enacted by the Toronto Stock Exchange (the “TSX”), the Canadian securities regulatory authorities, the New York Stock Exchange (the “NYSE”) and the U.S. Securities Exchange Commission (“SEC”). The Company’s common shares are listed on the TSX and the NYSE. Sections 103.00 and 303A.11 of the NYSE Listed Company Manual permit “foreign private issuers” (as defined in Rule 3b-4 under the Exchange Act) like the Company to follow home country practices in lieu of certain provisions of the NYSE Listed Company Manual. A description of the significant ways in which the Company’s corporate governance practices differ from those followed by domestic companies pursuant to NYSE standards is as follows:

Table of Contents

Shareholder Meeting Quorum Requirement: The NYSE is of the opinion that the quorum required for any meeting of shareholders should be sufficiently high to ensure a representative vote. The Company’s quorum requirement is set forth in its By-laws. A quorum for a meeting of the Company’s shareholders is (a) two persons present in person, each holding or representing by proxy at least one issued share of Enerflex, for the choice of a chair of the meeting and for the adjournment of the meeting to a fixed time and place and (b) for all other purposes, two persons present and holding or representing by proxy not less than 10% of the total number of Enerflex common shares entitled to be voted at the meeting.

Shareholder Approval Requirement: The NYSE rules for U.S. domestic issuers require shareholder approval of certain transactions or series of related transactions that result in the issuance of common shares, or securities convertible into or exercisable for common shares, that have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding prior to the transaction or if the issuance of common shares, or securities convertible into or exercisable for common shares, are, or will be upon issuance, equal to or in excess of 20% of the number of common shares outstanding prior to the transaction.

The Company intends to follow TSX rules for shareholder approval of new issuances of its common shares. In accordance with TSX rules, shareholder approval is required for certain issuances of shares that: (i) materially affect control of the Company; or (ii) provide consideration to insiders in an aggregate of 10% or greater of the market capitalization of the Company and have not been negotiated at arm’s length. Shareholder approval is also required under TSX rules in the case of private placements: (a) for an aggregate number of listed securities issuable greater than 25% of the number of securities of the listed issuer which are outstanding, on a non-diluted basis, prior to the date of closing of the transaction if the price per security is less than the market price; or (b) that during any six-month period are to insiders for listed securities or options, rights or other entitlements to listed securities greater than 10% of the number of securities of the listed issuer which are outstanding, on a non-diluted basis, prior to the date of the closing of the first private placement to an insider during the six-month period.

Equity Compensation Plans: The NYSE rules for U.S. domestic issuers require shareholder approval of all equity compensation plans (as defined in the NYSE rules) regardless of whether new issuances, treasury shares or shares that the Company has purchased in the open market are used. Unlike the NYSE rules, there is no requirement in Canada for shareholder approval of compensation arrangements settled solely in cash or with shares purchased in the open market at fair value or for amendments to such arrangements. Enerflex intends to comply with the TSX rules that require a listed company to obtain shareholder approval of any share compensation arrangement that involves the issuance of shares from treasury or to make amendments to such arrangements that require shareholder approval (in accordance with the TSX rules and the terms of such arrangement).

The foregoing is consistent with Canadian laws, customs and practices.

RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION

The Company’s Incentive Compensation Recovery Policy is filed as Exhibit 97 to this annual report on Form 40-F.

UNDERTAKING

The Company undertakes to make available, in person or by telephone, representatives to respond to inquiries made by the SEC staff, and to furnish promptly, when requested to do so by the SEC staff, information relating to: the securities in relation to which the obligation to file an annual report on Form 40-F arises; or transactions in said securities.
