NOVEMBER 18, 2021 2021 4TH QUARTER & FISCAL 2021 EARNINGS CALL Exhibit 99.2

Disclosure notice This presentation contains information about management's view of the Company's future expectations, plans and prospects that constitute forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. In addition, oral statements made by our directors, officers and employees to the investor and analyst communities, media representatives and others, depending upon their nature, may also constitute forward-looking statements. Forward-looking statements can be identified by the fact that they do not relate strictly to historic or current facts and often use words such as “anticipate,” “estimate,” “expect,” “believe,” “will likely result,” “outlook,” “project” and other words and expressions of similar meaning. Investors are cautioned not to place undue reliance on forward-looking statements. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including, but not limited to, those set forth in the "Risk Factors" section of the Company's Form 10-K for the fiscal year ended September 30, 2020 and subsequent filings with the U.S. Securities and Exchange Commission. The Company may not succeed in addressing these and other risks. Consequently, all forward-looking statements in this presentation are qualified by the factors, risks and uncertainties contained therein. In addition, the forward-looking statements included in this presentation represent the Company's views as of the date of this presentation and these views could change. However, while the Company may elect to update these forward-looking statements at some point, the Company specifically disclaims any obligation to do so, other than as required by federal securities laws. These forward-looking statements should not be relied upon as representing the Company's views as of any date subsequent to the date of this presentation. This presentation contains references to certain financial measures that are not presented in accordance with United States Generally Accepted Accounting Principles (“GAAP"). The Company uses non-GAAP financial measures to evaluate financial performance, analyze underlying business trends and establish operational goals and forecasts that are used when allocating resources. The Company believes these non-GAAP financial measures permit investors to better understand changes over comparative periods by providing financial results that are unaffected by certain items that are not indicative of ongoing operating performance. While the Company believes these measures are useful to investors when evaluating performance, they are not prepared and presented in accordance with GAAP, and therefore should be considered supplemental in nature. The Company’s non-GAAP financial measures should not be considered in isolation or as a substitute for other financial performance measures presented in accordance with GAAP. These non-GAAP financial measures may have material limitations including, but not limited to, the exclusion of certain costs without a corresponding reduction of net income for the income generated by the assets to which the excluded costs relate. In addition, these non-GAAP financial measures may differ from similarly titled measures presented by other companies. A reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure can be found in the Appendix as well as Company’s latest Form 8-K, filed with the SEC on November 18, 2021.
