Non-GAAP Measures

Management utilizes Adjusted EBITDA, an unaudited financial measure that is not calculated in accordance with General Accepted Accounting Principles ("GAAP"), to evaluate the Company's financial results and performance and to plan and forecast future periods. Investors are encouraged to review the Company's complete results of operations and additional information provided in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2023. Management believes that Adjusted EBITDA reflects an additional way of viewing aspects of the Company's operations that, when viewed in conjunction with GAAP results, provides a more complete understanding of the Company's results of operations and the factors and trends affecting its business.

Although we are providing management guidance on anticipated Adjusted EBITDA, we are unable to determine with reasonable certainty the ultimate outcome of certain items necessary to calculate net income, the most directly comparable GAAP measure, without unreasonable effort. These items include, but are not limited to, final calculation of investment related gains/losses, inventory reserves, profit transfers, revenue discounts, returns, chargebacks and stock-based compensation. These items are uncertain, depend on various factors, and could have a material impact on the GAAP reported results for the period. All estimates presented are subject to completion of the applicable quarter-end closing procedures. Our actual results for such period are not expected to be available until early August 2023 and may vary from these estimates. In addition, estimated financial information is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the estimated financial information described above will not materialize or will vary significantly from actual results. Accordingly, undue reliance should not be placed on this estimate. The preliminary estimate is not necessarily indicative of any future period and should be read together with the sections titled "Risk Factors" and "Special Note Regarding Forward-Looking Statements," and under similar headings in the documents filed by the Company with the U.S. Securities and Exchange Commission ("SEC") as well as our financial statements, related notes and other financial information included in the Company's filings with the SEC.

The foregoing guidance on anticipated results for the three months ended June 30, 2023, has not been reviewed by our auditors, is based on preliminary information as of the date hereof and is subject to material changes following completion of the quarter-end review process and other adjustments that may be made before our financial results are finalized. In addition, these preliminary unaudited results are not comprehensive financial results for the quarter ended June 30, 2023, should not be viewed as a substitute for complete GAAP financial statements or more comprehensive financial information, and are not indicative of the results for any future period.
