The forward-looking statements contained in this presentation are based on our current expectations and beliefs concerning future developments, as well as a number of assumptions concerning future events, and their potential effects on our business. These forward-looking statements are not guarantees of performance, and there can be no assurance that future developments affecting our business will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward- looking statements, which include, but are not limited to, our ability to achieve or maintain profitability, our ability to successfully execute our business and growth strategy, including realizing the expected benefits of our partnerships and acquisitions as well as other strategic initiatives we may enter into in the future, our ability to develop new product offerings and services, the potential c o n t i nu ed adverse effects of the ongoing global COVID-19 pandemic, including capacity constraints within the shipping industry, increased shipping costs and delays in the shipping of our energy storage products, projects delays and site closures and cost-overruns and other factors set forth under Item 1A."Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022, t o b e filed with the Securities and Exchange Commission ("SEC"), and in other filings we make with the SEC from time to time. New risks and uncertainties emerge from time to time and it is not possible for us to predict all such risk factors, nor can we assess the effect of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

Non-GAAP Financial Measures

Included in this presentation are certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Gross Profit (Loss), Adjusted Gross Profit Margin, Adjusted Net Income (Loss), and Free Cash Flow, which are designed to complement the financial information presented in accordance with GAAP because management believes such measures are useful to investors. Non-GAAP financial measures are not a substitute for or superior to measures of financial performance prepared in accordance with GAAP and should be not be considered as an alternative to any other Our non-GAAP metrics have limitations as analytical tools, and you should not consider them in isolation. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure.

See the Appendix to this presentation for a reconciliation of the non-GAAP financial measures to the nearest GAAP measure, which should be carefully evaluated.

A reconciliation of the Company's 2023 Adjusted Gross Profit guidance to the most directly comparable GAAP financial measure cannot be provided without unreasonable efforts and is not provided herein because of the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation.

In this Presentation, the Company relies on and refers to certain industry and market data and statistics obtained from third-party sources which it believes to be reliable. The Company has not independently verified the accuracy or completeness of any such third-party information. This data is subject to change. In addition, this Presentation does not purport to be all-inclusive or to contain all of the information that may be required to make a full analysis of the Company.
