GM before D&A is defined as gross margin excluding depreciation and amortization, which can vary based on the nature and origin of assets. The presentation of GM before D&A should not be considered in isolation from gross margin or as a replacement for measures prepared as determined under IFRS. Adjusted gross margin from recurring sources also referred to as recurring GM before D&A, is used to evaluate Enerflex’s recurring business, and it is defined as GM before D&A from the EI and AMS product lines 2) Enerflex defines bank-adjusted net debt to EBITDA as borrowings under the Revolving Credit Facility (“RCF”) and Notes less cash and cash equivalents, divided by EBITDA for the trailing 12-months, as defined by the Company’s lenders. 3) ROCE is a measure used to analyze operating performance and efficiency of the Company’s capital allocation process. The ratio is calculated by taking TTM EBIT divided by capital employed. Capital employed is average debt and shareholders’ equity less average cash for the trailing four quarters.
