Safe Harbor Statement and Use of Non-GAAP Financial Information

Safe Harbor Statement. Our presentation today contains forward-looking statements about the Company's plans, strategies, goals, target, and prospects including the company's cost reduction initiative and expected benefits of such initiative, capital structure and go-to-market strategies. We will also describe the Company's future operating results and financial position. These forward-looking statements are based on information available to the Company as of the date of this presentation and are based on management's current views and assumptions. These forward-looking statements involve a number of known and unknown risks that could cause actual results to differ materially from those anticipated. Such risks include changes in market demand and the competition we face; market acceptance of new products; the risk that the Company's cost reduction initiative may not yield the anticipated benefits in the expected timeframe or at all, and the continued impact of the COVID-19 pandemic on the Company's business, including on its supply chain.

Information concerning other risks that could cause results to differ materially from our expectations is contained in the "Risk Factors" section of the Company's Annual Report on Form 10-K filed with the SEC on June 6, 2023. The Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made.

Use of Non-GAAPFinancial Information. In this presentation the Company will be discussing non-GAAP measures, adjusted EBITDA, which is calculated from results based on GAAP. These non-GAAP financial measures are provided to enhance your overall understanding of the Company's current financial performance and prospects for the future and are not comprehensive of the Company's financial results. Such measures should not be viewed as a substitute for the Company's financial statements prepared in accordance with GAAP. You can find a reconciliation of these metrics to the reported GAAP results in the reconciliation tables provided in the appendices to this presentation. A reconciliation of non-GAAP measures to corresponding GAAP metrics on a forward-looking basis is not available due to high variability and low visibility with respect to the charges which are excluded from these non-GAAP calculations.

Trademarks. This presentation contains trademarks, service marks, trade names, and copyrights of other companies, which are the property of their respective owners.
