5 USFS Aggressive Initial Attack Fire seasons have been trending longer with more extreme fire behavior, coupled with unprecedented demand for personnel and resources, which has required us to adapt over the past several years. With that in mind, we will continue to focus on safe, aggressive initial attack. We will make appropriate risk informed efforts to fully suppress small fires before they become large, complex incidents to ensure we can protect lives, property, valuable timber and natural resources. It is critical that we suppress fires as swiftly as possible to minimize the amount of fireline exposure and be ready for the next ignition. This means employing direct attack tactics when and where feasible to minimize fire size and time to containment when safe and practicable to do so.

14 Non-GAAP Financial Metrics (Consolidated) Adjusted EBITDA & Adjusted EBITDA Margin The computation of Adjusted EBITDA is defined as income (loss) before income taxes plus net interest and other financing expenses, and depreciation and amortization, adjusted on a consistent basis for certain non-recurring, unusual or non-operational items. These items include (i) restructuring, (ii) acquisition related costs, (iii) founder advisory fee expenses, (iv) stock-based compensation expense and (v) foreign currency loss (gain). Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by net sales. To supplement the Company’s consolidated financial statements presented in accordance with U.S. GAAP, Perimeter is providing a summary to show the computations of Adjusted EBITDA and Adjusted EBITDA Margin, which are non-GAAP measures used by the Company's management and by external users of Perimeter’s financial statements, such as debt and equity investors, commercial banks and others, to assess the Company’s operating performance as compared to that of other companies, without regard to financing methods, capital structure or historical cost basis. Adjusted EBITDA and Adjusted EBITDA Margin should not be considered alternatives to net income (loss), operating income (loss), cash flows provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP (in thousands).

16 Non-GAAP Financial Metrics (Consolidated) Adjusted Net Income and Adjusted Earnings Per Share The computation of Adjusted Earnings Per Share (“Adjusted EPS”) is defined as Adjusted Net Income (loss) divided by adjusted diluted shares. Adjusted Net Income is defined as net income (loss) plus amortization, certain non-recurring, unusual or non-operational items, and the tax impact of these non- GAAP adjustments. These adjustments include (i) restructuring, (ii) acquisition related costs, (iii) founder advisory fee expenses, (iv) stock-based compensation expense and (v) foreign currency loss (gain). Adjusted diluted shares is the weighted average diluted shares outstanding, adjusted by adding dilution for options and warrants excluded under U.S. GAAP due to a net loss, less dilution related to founders advisory fees. To supplement the Company’s condensed consolidated financial statements presented in accordance with U.S. GAAP, Perimeter is providing a summary to show the computations of Adjusted Net Income and Adjusted EPS, which are non-GAAP measures used by the Company's management and by external users of Perimeter’s financial statements, such as debt and equity investors, commercial banks and others, to assess the Company's operating performance as compared to that of other companies, without regard to financing methods, capital structure or historical cost basis. Adjusted EPS and Adjusted Net Income should not be considered alternatives to GAAP earnings per share (“GAAP EPS”), net income (loss), operating income (loss), cash flows provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP (in thousands, except share and per share data).
