Non-GAAP Financial Metrics

The Company provides non-GAAP financial measures for Adjusted EBITDA, Segment Adjusted EBITDA, Adjusted Net Income, and Adjusted Earnings Per Share data as supplemental information regarding the Company’s business performance. The Company believes that these non-GAAP financial measures are useful to investors because they provide investors with a better understanding of the Company’s past financial performance and future results. The Company’s management uses these non-GAAP financial measures when it internally evaluates the performance of its business and makes operating decisions, including internal operating budgeting, performance measurement, and discretionary compensation.

Adjusted EBITDA and Segment Adjusted EBITDA

Adjusted EBITDA and Segment Adjusted EBITDA are 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, (v) purchase accounting impact - inventory step up and (vi) foreign currency loss (gain). 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 EBITDA and Segment Adjusted EBITDA, 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 Segment Adjusted EBITDA should not be considered an alternative 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.

Adjusted Net Income and Adjusted Earnings Per Share

The computation of Adjusted Earnings Per Share (“Adjusted EPS”) is defined as Adjusted Net Income 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, (v) purchase accounting impact - inventory step up and (vi) foreign currency loss (gain). Adjusted diluted shares is the weighted average diluted shares outstanding, adjusted by adding dilution for options 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 (loss) 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.
