Non - GAAP to GAAP Reconciliation This presentation contains financial measures that are not calculated in accordance with generally accepted accounting princi ple s in the United States (GAAP). The non - GAAP financial measures are Adjusted EBITDA for the fiscal years ended September 30, 2018, 2019 and 2020 and the quarters ended December 31, 2019 and 2020. Adjust ed EBITDA as reported herein refers to a financial performance measure that excludes from net income (loss) income statement line items interest expense and income taxes (benefit) expense, as well as n on - cash charges for depreciation and amortization, stock option (benefit) expense, United Kingdom lease liability reversal benefit, non - recurring acquisition and integration costs and other non - recurring third p arty costs, such as recruiting costs, consulting fees related to the adoption of two accounting standards, and expenses for rebranding and new website launch. The non - GAAP financial information should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Management, however, believes that Adjusted EBITDA, when used in conjunction with the results presented in accordance with GAAP, may provide a more complet e u nderstanding of the Company's results and may facilitate a fuller analysis of the Company's results, particularly in evaluating performance from one period to another. Management has chosen to provide this supplemental information to investors, analysts, and other interested parties to enable th em to perform additional analyses of our results and to illustrate our results giving effect to the non - GAAP adjustments shown in the reconciliation. Management strongly encourages investors to review the Co mpany's consolidated financial statements and publicly filed reports in their entirety and cautions investors that the non - GAAP measures used by the Company may differ from similar measures used by other co mpanies, even when similar terms are used to identify such measures. 22 2018 2019 2020 2019 2020 GAAP Net loss $ (194,000) $ (790,000) $ (4,685,000) $(1,426,000) $ (366,000) Add back: Interest expense 274,000 642,000 1,490,000 311,000 347,000       Income taxes (benefit) expense (60,000) 4,000 147,000 97,000 33,000 Depreciation and amortization 1,875,000 2,673,000 4,074,000 749,000 1,101,000       Stock option expense 134,000 278,000 540,000 97,000 181,000 United Kingdom lease liability reversal benefit — (701,000) (180,000) (60,000) — Acquisition and integration costs 395,000 568,000 339,000 270,000 — Other non-recurring, third party costs — 160,000 823,000 443,000 — Adjusted EBITDA $2,424,000 $2,834,000 $ 2,548,000 $ 481,000 $ 1,296,000 Fiscal Year Ended Quarter Ended September 30, December 31,
