EI CONTRACT BACKLOG AND ES BACKLOG OF $1.5 BILLION AND $1.3 BILLION, RESPECTIVELY, PROVIDING STRONG OPERATIONAL VISIBILITY

REDUCED BANK ADJUSTED NET DEBT-TO-EBITDA RATIO2 TO 1.5X TIMES AT YEAR-END

NEWS RELEASE

CALGARY, Alberta, February 27, 2025 – Enerflex Ltd. (TSX: EFX) (NYSE: EFXT) (“Enerflex” or the “Company”) today reported its financial and operational results for the three and twelve months ended December 31, 2024.

All amounts presented are in U.S. Dollars (“USD”) unless otherwise stated.

Q4/24 FINANCIAL AND OPERATIONAL OVERVIEW

1 During the fourth quarter of 2024, the Company modified its calculation of free cash flow. Free cash flow is now defined as cash provided by (used in) operating activities, less total capital expenditures (growth and maintenance) for PP&E and EI assets, mandatory debt repayments, and lease payments, while proceeds on disposals of PP&E and EI assets are added back. Refer to the “Free Cash Flow” section of this press release for further details.

2 The Company defines bank-adjusted net debt to EBITDA as borrowings under the Revolving Credit Facility (“RCF”) and its 9.00% Senior Secured Notes due 2027 (the “Notes”) less cash and cash equivalents, divided by EBITDA as defined by the Company’s lenders for the trailing 12- months.

BALANCE SHEET AND LIQUIDITY

MANAGEMENT COMMENTARY

“We delivered a strong finish to the year, with solid operating results across Enerflex’s geographies and product lines,” said Marc Rossiter, Enerflex’s President and Chief Executive Officer. “Our Energy Infrastructure and After-Market Services business lines continue to provide steady, reliable performance and revenue streams, reinforcing Enerflex’s ability to deliver sustainable returns across our global platform. Our Engineered Systems business delivered solid performance throughout 2024, highlighted by strong project execution.”

Rossiter continued, “As we enter 2025, visibility across our business remains solid, underpinned by a $1.5 billion contract backlog for our Energy Infrastructure assets, the recurring nature of our After-Market Services business, and a $1.3 billion Engineered Systems backlog. By focusing on operational execution, optimizing our core business, and maintaining disciplined capital allocation, we expect to further reduce debt and create meaningful long-term value for our shareholders.”

Preet S. Dhindsa, Enerflex’s Senior Vice President and Chief Financial Officer, stated, “Enerflex delivered fourth-quarter results that exceeded the ranges included in our 2024 guidance. We are particularly pleased with our ongoing progress in efficiently managing working capital, lowering net finance costs, and optimizing the Company’s debt stack. Backed by Enerflex’s strong global leadership team and talented employees, we continue to enhance the profitability and resilience of our operations. Our focus remains on generating sustainable free cash flow, further improving our balance sheet health and positioning the Company for long-term growth and value creation.”

SUMMARY RESULTS

Enerflex's consolidated financial statements and notes (the "financial statements") and Management's Discussion and Analysis ("MD&A") as at December 31, 2024, can be accessed on the Company's website at www.enerflex.com and under the Company's SEDAR+ and EDGAR profiles at www.sedarplus.ca and www.sec.gov/edgar, respectively.

OUTLOOK

During 2025, Enerflex’s priorities include: (1) enhancing the profitability of core operations; (2) leveraging the Company’s leading position in core operating countries to capitalize on expected increases in natural gas and produced water volumes; and (3) maximizing free cash flow to further strengthen Enerflex’s financial position, provide direct shareholder returns, and invest in selective customer supported growth opportunities.

Industry Update

Enerflex’s preliminary outlook for 2025 reflects steady demand across its business lines and geographic regions. Operating results will be underpinned by the highly contracted EI product line and the recurring nature of AMS, which together are expected to account for approximately 65% of our gross margin before depreciation and amortization. Enerflex’s EI product line is supported by customer contracts, which are expected to generate approximately $1.5 billion of revenue during their current terms.

Complementing Enerflex's recurring revenue businesses is the ES product line, which carried a backlog of approximately $1.3 billion as at December 31, 2024, the majority of which is expected to convert into revenue over the next 12 months. During 2025, ES gross margin before depreciation and amortization is expected to be more consistent with the historical long-term average for this business line, reflective of the weakness in domestic natural gas prices during much of 2024 and a shift of project mix in Enerflex’s ES backlog. Notwithstanding, near-term revenue for this business line is expected to remain steady. Enerflex is encouraged by initial customer response to improved domestic natural gas prices, and the medium-term outlook for ES products and services continues to be attractive, driven by expected increases in natural gas and produced water volumes across Enerflex’s global footprint.

The Company continues to closely monitor geopolitical tensions across North America, including the potential application of tariffs. Based on currently available information, the direct impact of tariffs on Enerflex’s business is expected to be mitigated by the Company’s diversified operations and proactive risk management. Enerflex’s operations in the USA, Canada and Mexico are largely distinct in the customers and projects they serve, and the Company has been working to mitigate the impact of potential tariffs. The United States is Enerflex’s largest operating region, generating 45% of consolidated revenue in 2024 by destination of sale, and we believe the Company is well positioned to benefit from growth in domestic energy production. Enerflex’s operations in Canada and Mexico generated 10% and 3% of consolidated revenue in 2024, respectively.

Capital Spending

Enerflex is targeting a disciplined capital program in 2025, with total capital expenditures of $110 million to $130 million. This includes a total of approximately $70 million for maintenance and PP&E capital expenditures. Similar to 2024, disciplined capital spending will focus on customer supported opportunities in the USA and Middle East. Notably, the fundamentals for contract compression in the USA remain strong, led by expected increases in natural gas production in the Permian basin and capital spending discipline from market participants. Enerflex will continue to make selective customer supported growth investments in this business.

Capital Allocation

Providing meaningful direct shareholder returns is a priority for Enerflex. With the Company operating within its target leverage range of bank-adjusted net debt-to-EBITDA ratio of 1.5x to 2.0x, Enerflex is positioned to increase direct shareholder returns. This is reflected through the previously announced 50% increase of the Company’s quarterly dividend.

Going forward, capital allocation decisions will be based on delivering value to Enerflex shareholders and measured against Enerflex’s ability to maintain balance sheet strength. In addition to increases to the Company’s dividend, share repurchases, and disciplined growth capital spending, Enerflex will also consider reducing leverage below its target range to further improve balance sheet strength and lower net finance costs. Unlocking greater financial flexibility positions the Company to capitalize on opportunities to optimize its debt stack and respond to evolving market conditions.

DIVIDEND DECLARATION

Enerflex is committed to paying a sustainable quarterly cash dividend to shareholders. The Board of Directors has declared a quarterly dividend of CAD$0.0375 per share, payable on March 24, 2025, to shareholders of record on March 10, 2025. With this dividend declaration, Enerflex has shortened the number of calendar days between its record date and payment date to better align the Company’s dividend approach with peers.

NON-IFRS MEASURES

Throughout this news release and other materials disclosed by the Company, Enerflex employs certain measures to analyze its financial performance, financial position, and cash flows, including net debt-to-EBITDA ratio and bank-adjusted net debt-to-EBITDA ratio. These non-IFRS measures are not standardized financial measures under IFRS and may not be comparable to similar financial measures disclosed by other issuers. Accordingly, non-IFRS measures should not be considered more meaningful than generally accepted accounting principles measures as indicators of Enerflex's performance. Refer to "Non-IFRS Measures" of Enerflex's MD&A for the three months ended December 31, 2024, for information which is incorporated by reference into this news release and can be accessed on Enerflex's website at www.enerflex.com and under the Company's SEDAR+ and EDGAR profiles at www.sedarplus.ca and www.sec.gov/edgar, respectively.

Adjusted EBITDA

1 The Company included net earnings, income taxes, and net finance costs on a consolidated basis to reconcile to EBIT.

2 Net finance costs are considered corporate expenditures and therefore have not been allocated to reporting segments.

3 EBIT includes $2 million loss on redemption options associated with the Notes. Debt is managed within Corporate and is not allocated to reporting segments.

Free cash flow

The Company modified its calculation of free cash flow to include a deduction for growth capital expenditures and exclude the deduction for dividends paid. Free cash flow is now defined as cash provided by (used in) operating activities, less total capital expenditures (growth and maintenance) for PP&E and EI assets, mandatory debt repayments, and lease payments, while proceeds on disposals of PP&E and EI assets are added back. This modification is aimed at providing additional clarity into Enerflex’s free cash flow and help users of the financial statements assess the level of free cash generated to fund other non-operating activities. These activities could include dividend payments, share repurchases, and non-mandatory debt repayments. Free cash flow may not be comparable to similar measures presented by other companies as it does not have a standardized meaning under IFRS. Management has adopted this non-IFRS measure to improve comparability with its peers.

1 Enerflex also refers to cash provided by operating activities before changes in working capital and other as “Funds from operations” or “FFO”.

2 Enerflex also refers to cash provided by operating activities as “Cashflow from operations” or “CFO”.

Bank-adjusted net debt-to-ebitda ratio

The Company defines net debt as short- and long-term debt less cash and cash equivalents at period end, which is then divided by EBITDA for the trailing 12 months. In assessing whether the Company is compliant with the financial covenants related to its debt instruments, certain adjustments are made to net debt and EBITDA to determine Enerflex's bank-adjusted net debt-to-EBITDA ratio. These adjustments and Enerflex's bank-adjusted net-debt-to EBITDA ratio are calculated in accordance with, and derived from, the Company's financing agreements.

Gross Margin before Depreciation and Amortization

Gross margin before depreciation and amortization is a non-IFRS measure defined as gross margin excluding the impact of depreciation and amortization. The historical costs of assets may differ if they were acquired through acquisition or constructed, resulting in differing depreciation. Gross margin before depreciation and amortization is useful to present operating performance of the business before the impact of depreciation and amortization that may not be comparable across assets.
