Disclaimer Special Note Regarding Forward-Looking Statements Some of the information in this presentation may contain forward-looking statements. Forward-looking statements give our current expectations, contain projections of results of operations or of financial condition, or forecasts of future events. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” “continue,” “will” and similar expressions are used to identify forward-looking statements. They can be affected by assumptions used or by known or unknown risks or uncertainties. Consequently, no forward-looking statements can be guaranteed. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements in this presentation. Actual results may vary materially. You are cautioned not to place undue reliance on any forward-looking statements. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include fluctuations in wealth management fees, our reliance on our partner firms and the principals who manage their businesses, our ability to make successful acquisitions, unknown liabilities of or poor performance by acquired businesses, harm to our reputation, our inability to facilitate smooth succession planning at our partner firms, our inability to compete, our reliance on key personnel, our inability to attract, develop and retain talented wealth management professionals, our inability to retain clients following an acquisition, write down of goodwill and other intangible assets, our failure to maintain and properly safeguard an adequate technology infrastructure, cyber-attacks, our inability to recover from business continuity problems, inadequate insurance coverage, the termination of management agreements by management companies, our inability to generate sufficient cash to service all of our indebtedness, the failure of our partner firms to comply with applicable U.S. and non-U.S. regulatory requirements, legal proceedings and governmental inquiries and certain other factors. All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements. Our forward-looking statements speak only as of the date of this presentation or as of the date as of which they are made. Except as required by applicable law, including federal securities laws, we do not intend to update or revise any forward-looking statements. Non-GAAP Financial Measures We analyze our performance using Adjusted Net Income and Adjusted Net Income Per Share. Adjusted Net Income and Adjusted Net Income Per Share are non-GAAP measures. We define Adjusted Net Income as net income (loss) excluding income tax expense (benefit), amortization of debt financing costs, intangible amortization and impairments, if any, non-cash equity compensation expense, non-cash changes in fair value of estimated contingent consideration, gain on sale of investment, loss on extinguishment of borrowings, delayed offering cost expense, management contract buyout, if any, and other one-time transaction expenses. The calculation of Adjusted Net Income also includes adjustments to reflect (i) a pro forma 27% income tax rate assuming all earnings of Focus LLC were recognized by Focus Inc. and no earnings were attributable to non-controlling interests and (ii) tax adjustments from intangible asset related income tax benefits from acquisitions based on a pro forma 27% tax rate. We believe that Adjusted Net Income and Adjusted Net Income Per Share, viewed in addition to and not in lieu of, our reported GAAP results, provide additional useful information to investors regarding our performance and overall results of operations for various reasons, including the following: (i) non-cash equity grants made to employees or non-employees at a certain price and point in time do not necessarily reflect how our business is performing at any particular time; stock-based compensation expense is not a key measure of our operating performance, (ii) contingent consideration or earn outs can vary substantially from company to company and depending upon each company’s growth metrics and accounting assumption methods; the non-cash changes in fair value of estimated contingent consideration is not considered a key measure in comparing our operating performance, and (iii) amortization expenses can vary substantially from company to company and from period to period depending upon each company’s financing and accounting methods, the fair value and average expected life of acquired intangible assets and the method by which assets were acquired; the amortization of intangible assets obtained in acquisitions are not considered a key measure in comparing our operating performance. Adjusted Net Income and Adjusted Net Income Per Share do not purport to be an alternative to net income (loss) or cash flows from operating activities. The terms Adjusted Net Income and Adjusted Net Income Per Share are not defined under GAAP, and Adjusted Net Income and Adjusted Net Income Per Share are not a measure of net income (loss), operating income or any other performance or liquidity measure derived in accordance with GAAP. Therefore, Adjusted Net Income and Adjusted Net Income Per Share have limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are: (i) Adjusted Net Income and Adjusted Net Income Per Share do not reflect all cash expenditures, future requirements for capital expenditures or contractual commitments, (ii) Adjusted Net Income and Adjusted Net Income Per Share do not reflect changes in, or cash requirements for, working capital needs, and (iii) Other companies in the financial services industry may calculate Adjusted Net Income and Adjusted Net Income Per Share differently than we do, limiting its usefulness as a comparative measure. In addition, Adjusted Net Income and Adjusted Net Income Per Share can differ significantly from company to company depending on strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. We compensate for these limitations by relying also on the GAAP results and use Adjusted Net Income and Adjusted Net Income Per Share as supplemental information. Please refer to the Appendix of this presentation for reconciliations of these measures to the most applicable GAAP measure. 2
