GREENLANE DISCLAIMER NASDAQ: GNLN CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This presentation contains, and oral statements made by representatives of Greenlane Holdings, Inc. (the "Company") in connection with this presentation may contain, forward-looking statements that are based on current expectations, forecasts and projections, including (but not limited to): capital market conditions, the current and future performance of the Company's business; the Company's long-term financial targets; growth in demand for the Company's products; growth in the market for cannabis, nicotine and hemp-derived CBD accessories; the Company's marketing and commercialization efforts; and the Company's financial outlook and expectations. Forward-looking statements should not be read as a guarantee of future performance or results and will not necessarily be accurate indications of the times at, or by which, such performance or results will be achieved. Forward-looking information is based on information available at the time and/or management's good faith belief with respect to future events, and is subject to risks and uncertainties, some or all of which are not predictable or within the control of the Company, that could cause actual performance or results to differ materially from those expressed in the forward-looking statements. Forward-looking statements speak only as of the date the statements are made. The Company assumes no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information. If the Company does update one or more forward-looking statements, no inference should be drawn that the Company will make additional updates with respect thereto or with respect to other forward-looking statements. Factors that could cause results to differ include those set forth in the sections captioned "Cautionary Note Regarding Forward-Looking Statements" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and the Company's other filings with the Securities and Exchange Commission. Non-GAAP Financial Measures This presentation information includes non-GAAP financial measures such as Adjusted EBITDA and Adjusted Selling, General & Administrative Expenses ("Adjusted SG&A"). Non-GAAP financial measures should be considered only as supplemental to, and not as superior to, financial measures prepared in accordance with GAAP. Other companies may use similarly titled non-GAAP financial measures that are calculated differently from the way the Company calculates such non-GAAP financial measures. Accordingly, the Company's non-GAAP financial measures may not be comparable to similar measures used by other companies. We caution investors not to place undue reliance on such non-GAAP measures, but instead to consider them together with the most directly comparable GAAP measure. Non-GAAP financial measures have limitations as analytical tools, and should not be considered in isolation, or as a substitute for the Company's results as reported under GAAP. Definition of these measures and a reconciliation of non-GAAP measures to the most directly comparable financial measure prepared in accordance with GAAP is included in the sections captioned "Adjusted EBITDA Reconciliation" and "Adjusted SG&A Reconciliation" on slides 26 and 27 of this presentation. Use of Market Data We use market data throughout this presentation that has generally been obtained from publicly available information and industry publications. These sources generally state that the information they provide has been obtained from sources believed to be reliable, but that the accuracy and completeness of the information are not guaranteed. The forecasts and projections are based on industry surveys and the preparers' experience in the industry, and there is no assurance that any of the projected amounts will be achieved.
