Forward - Looking Statements This presentation contains forward - looking statements. Forward - looking statements include, but are not limited to, statements th at express the Company’s intentions, beliefs, expectations, strategies, predictions or any other statements related to the Co mpa ny’s future activities or future events or conditions. These statements are based on current expectations, estimates and projections abou t t he Company’s business based, in part, on assumptions made by the Company’s management. These statements are not guarantees of fu ture performances and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and r esu lts may differ materially from what is expressed or forecasted in the forward - looking statements due to numerous factors, includ ing those risks discussed in the Company’s annual report on Form 10 - K and in other documents that the Company files from time to time with the SEC. Any forward - looking statements speak only as of the date on which they are made, and the Company does not undertake an y obligation to update any forward - looking statement to reflect events or circumstances after the date of this report, except as r equired by law. Non - GAAP Financial Measures In addition to financial results reported in accordance with accounting principles generally accepted in the United States of Am erica ("GAAP"), the Company has provided the following non - GAAP financial measures in this release and the accompanying tables: adjusted EBITDA. Precision Optics uses this non - GAAP financial measures internally to facilitate period - to - period comparisons and analysi s of its operating performance and liquidity, and believes they are useful to investors as a supplement to GAAP measures in a nal yzing, trending and benchmarking the performance and value of our business. However, these measures are not intended to be a substit ute for those reported in accordance with GAAP. These measures may be different from non - GAAP financial measures used by other companies, even when similar terms are used to identify such measures. In order to calculate these non - GAAP financial measures, the Company makes targeted adjustments to certain GAAP financial line i tems found on its Consolidated Statement of Operations, backing out non - recurring or unique items or items that the Company beli eve otherwise distort the underlying results and trends of the ongoing business. We have excluded the following items from one or mo re of our non - GAAP financial measures for the periods presented: Selling, general and administrative expenses; operating expenses . The Company excludes a portion of SG&A expense and operating expenses related to transaction expenses related to acquisitio ns and financings. Acquisition - related expenses include transaction fees, due diligence costs and other direct costs associated with our acquisitions. These amounts are unrelated to our core performa nce during any particular period and are impacted by the timing of the acquisition. The Company excludes acquisition - related expens es from the Company’s SG&A expense and total operating expenses to provide investors a method to compare our operating results to pri or periods and to peer companies, as such amounts can vary significantly based on the frequency of acquisitions and the magnitud e o f acquisition expenses. Bad debt expense; operating expenses. The Company excludes a portion of SG&A expense and operating expenses related to bad debt expense. These amounts are unrelate d t o our core performance during any particular period. The Company believes it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare the Company’s res ult s with peer companies. Adjusted EBITDA is a non - GAAP financial measure that we define as GAAP net income (loss), adjusted to exclude non - recurring tran saction costs, bad debt expense, depreciation and amortization, non - cash stock - based compensation, interest expense, and provisi on (benefit) for income taxes. We believe that the use of adjusted EBITDA is useful to investors and other users of the Company' s f inancial statements in evaluating our operating performance because it provides them with an additional tool to compare busin ess performance across companies and across periods. The Company uses adjusted EBITDA in conjunction with traditional GAAP operat ing performance measures as part of our overall assessment of our performance, for planning purposes, including the preparation o f our annual operating budget, to evaluate the effectiveness of our business strategies and to communicate with our board of direct ors concerning our financial performance. Management does not place undue reliance on adjusted EBITDA as its only measure of oper at ing performance. Adjusted EBITDA should not be considered as a substitute for other measures of financial performance reported in ac cordance with GAAP. 2
