Any data on past performance contained herein is no t an indication as to future performance. Except as required by applicable law, the Company assumes no obligation to update t he information in this Investor Presentation. Nothing herein shall be deemed to constitute investment, legal, tax, financial, ac cou nting or other advice. The communication of this Investor Presentation is restricted by law, and it is not intended for dist rib ution to, or use by any person in, any jurisdiction where such distribution or use would be contrary to local law or regulation. No representation or wa rranty (whether express or implied) has been made by the Company with respect to the matters set forth in this Investor Pres ent ation. Forward Looking Statements Certain statements included in this Investor Presentation are not historical facts but are forward - looking statements for purpos es of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward - looking stat ements may include projections and estimates concerning our possible or assumed future results of operations, financial condition, busin ess strategies and plans, market opportunity, competitive position, industry environment, and potential growth opportunities. In s ome cases, you can identify forward - looking statements by terms such as "may," "will," "should," "design," "target," "aim," "expect," "could," "intend," "plan," "anticipate," "estimate," "believe," "continue," "predict," "project," "potential," "goal" or other words tha t convey the uncertainty of future events or outcomes. You can also identify forward - looking statements by discussions of strategy, plans or intentions. Th ese forward - looking statements include, but are not limited to, statements regarding future revenue, Adjusted EBITDA, Adjusted E BITDA Margin, debt, capital expenditure and cash flow estimates and forecasts of other financial and performance metrics (includin g k ey performance indicators), and projections of market size and opportunity. These statements are based on various assumptions an d on the current expectations of the Company and its management and are not predictions of actual performance. While our management co nsi ders these assumptions and expectations to be reasonable, they are inherently subject to significant business, economic, com pet itive, regulatory and other risks, contingencies and uncertainties, including continuing impact of the COVID - 19 pandemic, and other ris ks, most of which are difficult to predict and many of which are beyond our control. If the risks materialize or our assumpt ion s prove incorrect, actual results could differ materially from the results implied by these forward - looking statements. There may be add itional risks that the Company currently believes are immaterial that could also cause actual results to differ from those c ont ained in the forward - looking statements. In addition, forward looking statements reflect the Company's expectations, plans or forecasts of f uture events and views as of the date of this Investor Presentation. The Company anticipates that subsequent events and devel opm ents will cause these assessments to change. However, while the Company may elect to update these forward - looking statements at some poin t in the future, the Company specifically disclaims any obligation to do so. These forward - looking statements should not be reli ed upon as representing the Company's assessments as of any date subsequent to the date of this Investor Presentation. Market and Industry Data This Investor Presentation contains references to industry market data and certain industry forecasts. Industry market data a nd industry forecasts are obtained from publicly available information and industry publications. Industry publications general ly state that the information contained therein has been obtained from sources believed to be reliable, but that the accuracy and completeness of that information is not guaranteed. Although we believe industry information to be accurate, it is not independently verifie d b y us. Some data is also based on our good faith estimates, which are derived from our review of internal surveys or data, as welI as the independent sources referenced above. Assumptions and estimates of our and our industry's future performance are nece ss arily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause future performance to differ ma terially from our assumptions and estimates. Non - GAAP Financial Measures This Investor Presentation includes key performance indicators and non - GAAP financial metrics that we use to help us evaluate ou r business, identify trends affecting our business, formulate business plans, and make strategic decisions. Adjusted EBITDA and Adjusted EBITDA Margin are financial measures that are calculated and presented on the basis of methodologies other than in accordance wi th generally accepted accounting principles in the United States of America ("GAAP"). Any non - GAAP financial measures used in t his Investor Presentation are in addition to, and not meant to be considered superior to, or a substitute for, the Company's fin anc ial statements prepared in accordance with GAAP. A reconciliation of each of these non - GAAP measures to their nearest GAAP meas ure is set forth in page 28 of this Investor Presentation. The Company believes these non - GAAP measures of financial results provide useful information to management and investors regardi ng certain financial and business trends relating to our financial condition and results of operations. The Company's manage men t uses these non - GAAP measures to compare our performance to that of prior periods for trend analyses and for budgeting and planning pu rposes. These measures are used in monthly financial reports prepared for management and our board of directors. We believe tha t the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating r esults and trends in and in com paring our financial measures with other similar companies, many of which present similar non - GA AP financial measures to investors. Management does not consider these non - GAAP measures in isolation or as an alternative to financial meas ures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that they exclude sign ificant expenses and income that are required by GAAP to be recorded in our financial statements. In addition, they are subject to i nhe rent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or incl ude d in determining these non - GAAP financial measures. Undue reliance should not be placed on these measures as the Company's only measu res of operating performance, nor should such measures be considered in isolation from, or as a substitute for, financial in for mation presented in compliance with GAAP. Non - GAAP financial measures as used in respect of the Company may not be comparable to simila rly titled amounts used by other companies. Additional information with respect to the Company is contained in its filings with the SEC and is available at the SEC's web sit e, http://www.sec.gov , and on the Company's website, https://medirom.co.jp/en/ .
