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 Alvarium Tiedemann. The general explanations included in this Presentation cannot address, and are not intended to address, your specific investment objectives, financial situations or financial needs. Forward-Looking Statements Some of the statements in this presentation may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking. Words such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “future,” “intend,” “may,” “plan” and “will” and similar expressions identify forward-looking statements. Forward-looking statements reflect management’s current plans, estimates and expectations and are inherently uncertain. The inclusion of any forward- looking information in this presentation should not be regarded as a representation that the future plans, estimates or expectations contemplated will be achieved. Forward-looking statements are subject to various risks, uncertainties and assumptions. Important factors that could cause actual results to differ materially from those in forward-looking statements include, but are not limited to, global and domestic market and business conditions, successful execution of business and growth strategies and regulatory factors relevant to our business, as well as assumptions relating to our operations, financial results, financial condition, business prospects, growth strategy and liquidity and the risks and uncertainties described in greater detail under “Risk Factors” included in Alvarium Tiedeman's registration statement on Form S-1 filed January 27, 2023, and in the subsequent reports filed with the Securities and Exchange Commission, as such factors may be updated from time to time. We undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law.

Disclosures (Cont.) Financial Information The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X promulgated under the Securities Act. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any registration statement that may be filed by Alvarium Tiedeman. Due to rounding, numbers presented throughout this Presentation may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures. Use of Non-GAAP Financial Measures The non-GAAP financial measures contained in this presentation (including, without limitation, Combined Adjusted Net Income, Combined Adjusted EBITDA and Combined Economic EBITDA) are not GAAP measures of Alvarium Tiedemann’s financial performance or liquidity and should not be considered as alternatives to net income (loss) as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with GAAP. A reconciliation of such non-GAAP measures to their most directly comparable GAAP measure is included on page 43 of this presentation. You are encouraged to evaluate each adjustment to non-GAAP financial measures and the reasons management considers it appropriate for supplemental analysis. Alvarium Tiedemann believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. Our presentation of these measures should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. In addition, these measures may not be comparable to similarly titled measures used by other companies in our industry or across different industries. Forward-looking Non-GAAP The Company is not able to reconcile its forward-looking non-GAAP estimates of Adjusted EBITDA margin without unreasonable effort because of the inherent difficulty of accurately forecasting the occurrence and financial impact of the various adjusting items necessary for such reconciliation that have not yet occurred, are out of its control, or cannot be reasonably predicted, which could have a material impact on its future GAAP financial results. Industry and Market Data Certain information contained in this Presentation relates to or is based on studies, publications, surveys and Alvarium Tiedemann’s own internal estimates and research. In addition, all of the market data included in this Presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. Finally, while Alvarium Tiedemann believes its internal research is reliable, such research has not been verified by any independent source and none of Alvarium Tiedemann or any of its affiliates nor any of their respective control persons, officers, directors, employees or representatives make any representation or warranty with respect to the accuracy of such information. Trademarks This Presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this Presentation may be listed without the TM, SM © or ® symbols, but Alvarium Tiedemann, will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights.
