For the avoidance of doubt, please clarify which conditions are waivable and not waivable. Risk Factors Risks Relating to the Transaction Uncertain geopolitical conditions could adversely affect Enerflex s results of operations, page 73 3. We note that Enerflex sources natural gas from Russia. Please disclose whether and how Enerflex's business segments, products, lines of service, projects, or operations are materially impacted by supply chain disruptions in light of the conflict between Russia and Ukraine. For example, discuss whether Enerflex has: had to suspend the production, purchase, sale or maintenance of certain items; experienced higher costs due to constrained capacity or increased commodity prices; experienced surges or declines in consumer demand for which you are unable to adequately adjust your supply; or been unable to supply products at competitive prices or at all due to export restrictions, sanctions, or the ongoing conflict. 4. To the extent material, please disclose any known trends or uncertainties that have had or are reasonably likely to have a material impact on your liquidity, financial position, or results of operations arising from the conflict between Russia and Ukraine. Enerflex relies on suppliers to source raw materials, component parts and finished products..., page 75 5. We note your disclosure that "some of the components used in Enerflex s products are obtained from a single source or a limited group of suppliers." Please expand your disclosure to discuss with more specificity Enerflex's material sources for components, the availability of raw materials, and the identity of any principal suppliers. Background of the Transaction, page 95 6. We note statements made by Mr. Rossiter to the press following the announcement of the proposed transaction indicating that Enerflex has been considering a deal/combination with Exterran "literally for years." The discussion on page 96 suggests that March 15, 2021 was the first substantive discussion between Mr. Rossiter and Mr. Way about a potential transaction between Enerflex and Exterran. Please revise the disclosure to state whether the March 15 call was the first discussion between management of Enerflex and management of Exterran. Additionally, revise to disclose, to the extent applicable, whether Enerflex had prior internal discussions specifically about a potential acquistion or business combination with Exterran. Marc Rossiter FirstName LastNameMarc Rossiter Enerflex Ltd. Comapany April NameEnerflex Ltd. 20, 2022 April 320, 2022 Page 3 Page FirstName LastName Financial Analyses, page 117 7. Explain why the only companies selected for each of the respective Selected Public Companies Analyses are the parties to this business combination. Additionally, we note the assertion in the Exterran Financial Analyses that "none of the selected companies used in Wells Fargo Securities analyses is identical to Exterran" and a similar assertion in the Enerflex Financial Analyses with respect to Enerflex. Please clarify these statements given that both Exterran and Enerflex were "selected" companies for purposes of the analyses. Certain Unaudited Prospective Financial Information, page 122 8. Revise to disclose and quantify each material assumption underlying the projections, including but not limited to the assumptions and variables used with respect to general economic and competitive conditions and prevailing interest rates. Additionally, given that the sets of projections for each of Exterran and Enerflex were prepared using different assumptions, highlight the materially differing assumptions. Summary of Exterran Prospective Financial Information, page 124 9. We note that Exterran management prepared a separate sensitivity analysis that factored in an assumed equity raise, and that Wells Fargo Securities considered both the Status Quo Sensitivity and the Equity Issuance Sensitivity in connection with the selected public companies analysis and discounted cash flow analysis, which in turn were used by Wells Fargo Securities in formulating its fairness opinion. Accordingly, please provide disclosure of the Equity Issuance Sensitivity pursuant to Item 1015(b)(6) of Regulation M-A. Certain U.S. Federal Income Tax Consequences, page 134 10. We note that Enerflex and Exterran intend that the transaction will qualify as a reorganization within the meaning of Section 368(a) of the U.S. Internal Revenue Code. Given the parties' representation that a U.S. holder that exchanges shares of Exterran common stock for the merger consideration in the transaction will generally not recognize gain or loss other than with respect to any cash received in lieu of fractional Enerflex common shares, revise to include counsel's tax opinion as an exhibit as required by Item 601(b)(8) of Regulation S-K. 11. We note that your discussion is framed as a "general summary" only and "is not a complete description of all tax considerations that may be relevant." Revise to remove the implication that the discussion may not address all material federal tax consequences. Refer to Section III.C.1 of Staff Legal Bulletin 19.

Comapany April NameEnerflex Ltd. 20, 2022 April 520, 2022 Page 5 Page FirstName LastName Free Cash Flow, page 218 17. The title of your measure Free Cash Flow suggests that this is a non-IFRS liquidity measure. However we note that the measure adjusts cash flow from operating activities to exclude working capital changes. As such, it is unclear how this is a liquidity measure and why the title Free Cash Flow is appropriate. Please revise or advise. Ensure that any non-IFRS liquidity measures you present do not exclude charges that require or have required cash settlement. Refer to Item 10(e)(1)(ii)(A) of Regulation S-K and Question 103.1 of the commission s Non-GAAP Compliance and Disclosure Interpretations.
