Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Business	Description of the Business AlTi Global, Inc. is a multi-disciplinary financial services business, with a diverse array of investment, advisory, and administrative capabilities. The Company is a global organization that manages or advises approximately $68.2 billion in combined assets as of September 30, 2023. The Company provides holistic solutions for Wealth Management clients through a full spectrum of Wealth Management services, including discretionary investment management services, non-discretionary investment advisory services, trust services, administration services, and family office services. It also structures, arranges, and provides a network of investors with co-investment opportunities in a variety of alternative assets which are either managed intra-group or by carefully selected managers in the relevant asset class. The Company manages and advises both public and private investment funds. Amounts disclosed throughout this document for the three and nine month period ended September 30, 2023, relate to AlTi Global, Inc, the Successor company in the business combination. Amounts disclosed throughout this document for the three and nine month period ended September 30, 2022 relate to TWMH, the predecessor company. Due to the Business Combination and the conforming of significant accounting policies, the results of operations, cash flows, and other financial information for the Successor Period are not comparable to the Predecessor periods. Business Combination The Registrant was initially incorporated in the Cayman Islands as Cartesian Growth Capital, a special purpose acquisition company. In anticipation of the Business Combination: • The holders of the equity of the TIG Entities contributed their TWMH and TIG equity to Umbrella making TWMH and the TIG wholly owned subsidiaries of Umbrella. • Alvarium reorganized such that it became the wholly owned indirect subsidiary of AlTi Global Topco. • Cartesian SPAC formed Umbrella Merger Sub. Pursuant to the Business Combination on January 3, 2023: • The Registrant was redomiciled as a Delaware corporation and changed its name to Alvarium Tiedemann Holdings, Inc. Effective April 19, 2023, Alvarium Tiedemann Holdings, Inc. changed its name to AlTi Global, Inc. • The Registrant acquired all the outstanding share capital of AlTi Global Topco. • Umbrella Merger Sub, LLC merged into Umbrella with AlTi Global Capital, LLC, formerly known as Alvarium Tiedemann Capital, LLC as the surviving entity. • The Company acquired 51% of the equity interests of Umbrella, while the existing TWMH and TIG rollover shareholders hold a 49% economic interest in Umbrella. Umbrella holds 100% of the equity interests of TWMH, TIG, and Alvarium. • Through a series of intercompany transactions, AlTi was restructured to reflect the final structure depicted below: Capital Structure The Registrant has the following classes of shares and other instruments outstanding: • Class A Common Stock – Shares of Class A Common Stock that are publicly traded. Class A shareholders are entitled to declared dividends from shares of Class A Common Stock. As of September 30, 2023, the shares of Class A Common Stock represent 55% of the total voting power of all shares. • Class B Common Stock – Shares of Class B Common Stock that are not publicly traded. Class B shareholders are entitled to distributions declared by the Company’s board of directors. The distributions are paid by Umbrella. As of September 30, 2023, the shares of Class B Common Stock represent 45% of the total voting power of all shares. • Prior to the Business Combination, the Company issued warrants to purchase shares of Class A Common Stock at a price of $11.50 per share. Throughout the period from January 3, 2023 to March 31, 2023, 428,626 Warrants were exercised. On April 3, 2023, 78,864 Warrants were exercised. On June 7, 2023, the Company closed an offer and consent solicitation and entered into a warrant amendment, pursuant to which the remaining 19,892,387 Warrants were exchanged for 4,864,275 shares of Class A Common Stock. The exercises and exchanges throughout the period from January 3, 2023 to June 30, 2023 resulted in an increase in Additional Paid-in-Capital amount of $29.5 million. Following the exchanges, none of the Warrants were outstanding as of September 30, 2023. The following table presents the number of shares of the Registrant that were outstanding as of September 30, 2023: As of September 30, Class A Common Stock 64,770,908 Class B Common Stock 53,219,713 Segments Our business is organized into two operating segments: Wealth Management and Asset Management. Described below are the segments and the revenue generated by each, which broadly fall into three categories: recurring management, advisory, or administration fees; performance or incentive fees; and transaction fees. Wealth Management Within our Wealth Management segment, services provided principally consist of investment management and advisory services, trusts and administrative services, and family office services. The Wealth Management client base includes high net worth individuals, families, single family offices, foundations, and endowments globally. Investment management or advisory fees are the primary source of revenue in our Wealth Management segment. These fees are generally calculated based on a percentage of the value of each client’s billable AUM or AUA (as applicable). As of September 30, 2023, this segment had $48.5 billion in AUM/AUA. Investment Management and Advisory Services In our investment management and advisory services teams, we diversify our clients’ portfolios across risk factors, geographies, traditional asset classes such as money markets, equities and fixed income, and alternative asset classes including private equity, private debt, hedge funds, real estate, and other assets through highly experienced third-party managers. Trusts and Administration Services The trust and administration services that we provide include entity formation and management, creating or modifying trust instruments and/or administrative practices to meet beneficiary needs, full corporate, trustee-executor, and fiduciary services. We also offer provision of directors and company secretarial services, administering entity ownership of intellectual property rights, advice and administration services in connection with investments in marine and aviation assets, and administering entity ownership of fine art and collectibles. Family Office Services (FOS) Family office services are tailored outsourced family office solutions and administrative services which we provide primarily to our larger clients. These services include bookkeeping and back-office services, private foundation management and grantmaking, oversight of trust administration, financial tracking and reporting, cash flow management and bill pay, and other financial services. Asset Management Asset Management services include the alternatives platform and public and private real estate (including co-investment) businesses. Alternatives Platform The alternatives platform embodies our legacy TIG business, which is an alternative asset manager and includes our TIG Arbitrage strategy and funds managed by our External Strategic Managers, predominantly for institutional investors. The TIG Arbitrage strategy is an event-driven strategy fund that earns management fees and incentive fees based on the performance of its underlying funds and accounts. The investment strategies of the External Strategic Managers include Real Estate Bridge Lending, European Equities and Asian Credit and Special Situations. Distributions are received from the External Strategic Managers through profit or revenue sharing arrangements that are generated through management and incentive fees based on the performance of the underlying investments. As of September 30, 2023, this platform had $7.7 billion in AUM/AUA. Co-Investment Real estate co-investment oversees deal origination, documentation, and structuring from inception to exit for a variety of strategies, including development, income, value-add, and planning. Investors are typically HNWIs, single family offices, and institutional investors. Fees earned include private market, incentive fees, management and advisory fees, and placement and brokerage fees. As of September 30, 2023, our real estate co-investment platform had deployed more than $7.5 billion of capital (inclusive of capital raised for our public and private real estate funds), of which approximately 14% has been invested by legacy Alvarium shareholders and senior employees. Real Estate - Public and Private The real estate business includes fund management services as well as co-investment solutions. As of September 30, 2023, this business had approximately $12.0 billion of AUM/AUA. Fund Management Our real estate fund management business manages two funds based in the United Kingdom, LXi REIT plc (“LXi”), a publicly traded real estate investment trust, and Home Long Income Fund (“HLIF”) a private fund. Fees from our real estate fund management business are earned from management and advisory services. Exit from management of Home REIT PLC Prior to the Business Combination, AlTi RE Limited, formerly known as Alvarium RE Limited (“ARE”), an indirect wholly owned subsidiary of Alvarium, entered into an agreement to sell 100% of the equity of Alvarium Home REIT Advisors Ltd. (“AHRA”), the advisor to the publicly-traded fund Home REIT Plc (“Home REIT”), to a newly formed entity (“NewCo”) owned by the management of AHRA, for aggregate consideration approximately equal to $29 million. The consideration comprised a promissory note maturing December 31, 2023, subject to extension if mutually agreed upon by the parties thereto. Additionally, ARE was granted a call option pursuant to which ARE had the right to repurchase AHRA prior to the repayment of the note for a purchase price equal to the note balance then outstanding thereunder. Subsidiaries are companies over which a company has the power indirectly and/or directly to control the financial and operating policies so as to obtain benefits. In assessing control for accounting purposes, potential voting rights that are presently exercisable or convertible (including rights which may arise on the exercise of an option) are taken into account. With respect to the AHRA, the above arrangements resulted in AHRA continuing to be consolidated by AlTi after its legal disposal to NewCo. Due to this consolidation, after the Business Combination, an intangible asset was recognized related to the investment advisory agreement between AHRA and Home REIT. On June 30, 2023, the Company entered into a series of agreements that resulted in the deconsolidation of AHRA from the Asset Management segment with immediate effect. The agreements removed ARE’s potential controlling voting rights in AHRA (previously ascertainable on the exercise of the option), and terminated other residual contractual relationships between AHRA and ARE. As a result, these agreements removed AlTi’s control of AHRA from an accounting perspective. AHRA’s results are included in the Company’s Condensed Consolidated Statement of Operations for the period from January 3, 2023 to June 30, 2023, and its accounts were removed from the Consolidated Statement of Financial Position as of June 30, 2023. The deconsolidation resulted in an intangible asset impairment charge of $29.4 million, which is recorded in Impairment loss on goodwill and intangible assets in the Condensed Consolidated Statement of Operations. Assets managed by AHRA, however, have been excluded from the Company’s AUM/AUA metrics since January 3, 2023.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements comprise the financial statements of the Company and its subsidiaries for the period from January 3, 2023 to September 30, 2023 and the Condensed Consolidated Statement of Financial Position of TWMH and its subsidiaries as of December 31, 2022 and the Condensed Consolidated Statement of Operations of TWMH for the period from January 1, 2022 to September 30, 2022. The condensed consolidated financial statements have been prepared under the accrual basis of accounting in accordance with U.S. GAAP and conforms to prevailing practices within the financial services industry, as applicable to the Company. The notes are an integral part of the Company’s condensed consolidated financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements have been included and are of a normal and recurring nature. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior period presentations and disclosures, while not required to be recast, may be reclassified to ensure comparability with current period classifications. (b) Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make assumptions and estimates that affect the amounts reported in the condensed consolidated financial statements of the Company. The most critical of these estimates are related to (i) the fair value of the investments included in the Billable Assets within AUM/AUA, as this impacts the amount of revenues the Company recognizes each period; (ii) the fair values of the Company’s investments and liabilities with respect to the TRA, Warrants, and Earn-out Securities, as changes in these fair values have a direct impact on the Company’s consolidated net income (loss); (iii) the estimate of future taxable income, which impacts the realizability and carrying amount of the Company’s deferred income tax assets; (iv) the qualitative and quantitative assessments of whether impairments of equity method investments, carried interest vehicles, acquired intangible assets, and goodwill exist; and (v) the determination of whether to consolidate a variable interest entity (“VIE”); and (vi) fair value of assets acquired and liabilities assumed in business combinations, including assumptions with respect to future cash inflows and outflows, discount rates, assets useful lives, market multiples, the allocation of purchase price consideration in the business combination valuation of acquired assets and liabilities, the estimated useful lives of intangible assets, goodwill impairment testing, assumptions used to calculate equity-based compensation, and the realization of deferred tax assets. Inherent in such estimates are judgements relating to future cash flows, which include the Company’s interpretation of current economic indicators and market valuations, and assumptions about the Company’s strategic plans with regard to its operations. While management believes that the estimates utilized in preparing the condensed consolidated financial statements are reasonable and prudent, actual results could differ materially from those estimates. (c) Consolidation The Company consolidates those entities in which it has a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. The Company determines whether an entity should be consolidated by first evaluating whether it holds a variable interest in the entity. Entities that are not VIEs are further evaluated for consolidation under the voting interest model (“VOE” model). An entity is considered to be a VIE if any of the following conditions exist: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) the holders of equity investment at risk, as a group, lack either the direct or indirect ability through voting rights or similar rights to make decisions that have a significant effect on the success of the entity or the obligation to absorb the expected losses or right to receive the expected residual returns, or (c) the voting rights of some equity investors are disproportionate to their obligation to absorb losses of the entity, their rights to receive returns from an entity, or both and substantially all of the entity’s activities either involve or are conducted on behalf of an investor with disproportionately few voting rights. Fees that are customary and commensurate with the level of services provided by the Company, and where the Company does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, are not considered a variable interest. The Company factors in all economic interests, including proportionate interests through related parties, to determine if fees are considered a variable interest. Where the Company’s interests in funds are primarily management fees and insignificant direct or indirect equity interests through related parties, the Company is not considered to have a variable interest in such entities. The Company consolidates all VIEs for which it is the primary beneficiary. An entity is determined to be the primary beneficiary if it holds a controlling financial interest, which is defined as having (a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company does not consolidate any of the products it manages as it does not hold any direct or indirect interests in such entities that could expose the Company to an obligation to absorb losses of an entity or the right to receive benefits from an entity that could potentially be significant to such entities. The Company determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and continuously reconsiders that conclusion. In evaluating whether the Company is the primary beneficiary, the Company evaluates its direct and indirect economic interests in the entity. The consolidation analysis is generally performed qualitatively, however, if the primary beneficiary is not readily determinable, a quantitative analysis may also be performed. This analysis requires judgment, including: (1) determining whether the equity investment at risk is sufficient to permit the entity to finance its activities without additional subordinated financial support, (2) evaluating whether the equity holders, as a group, can make decisions that have a significant effect on the success of the entity, (3) determining whether two or more parties’ equity interests should be aggregated, (4) determining whether the equity investors have proportionate voting rights to their obligations to absorb losses or rights to receive returns from an entity and (5) evaluating the nature of relationships and activities of the parties involved in determining which party within a related-party group is most closely associated with a VIE and therefore would be deemed the primary beneficiary. Under the voting interest model, the Company consolidates those entities it controls through a majority voting interest. The Company will generally not consolidate those voting interest entities where a single investor or simple majority of third-party investors with equity have the ability to exercise substantive kick-out or participation rights. (d) Revenue Recognition Revenue is recognized when the Company transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those goods or services. A five-step framework is utilized that requires an entity to: (i) identify the contract(s) with a customer, which includes assessing the collectability of the consideration to which it will be entitled in exchange for the goods or services transferred to the customer, (ii) identify the performance obligation in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligation in the contract, and (v) recognize revenue when the entity satisfies a performance obligation. Management/Advisory Fees Revenues from contracts with customers consist of investment management, trustee, and custody fees. The Company recognizes revenue at the time of transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue recognized is calculated based on contractual terms, including the transaction price, whether a distinct performance obligation has been satisfied and control is transferred to the customer, and when collection of the revenue is assessed as probable. Investment management, trustee and custody fees are recognized over the period in which the investment management services are performed, using a time-based output method to measure progress. The amount of revenue varies from one reporting period to another as levels of AUA change (from inflows, outflows, and market movements) and the number of days in the reporting period change. For services provided to each client account, the Company charges an investment management fee, inclusive of custody and/or trustee fees, based on the fair value of the AUA of such account representing a single performance obligation. For assets for which valuations are not available on a daily basis, the most recent valuation provided to the Company is used as the fair value for the purpose of calculating the quarterly fee. In certain circumstances, fixed fees are charged to customers on a monthly basis. The nature of the Company’s performance obligation is to provide a series of distinct services in which the customer receives the benefits of the services over time. The Company’s performance obligation is satisfied at the end of each month or quarter, as applicable to the contract with the customer. Fees are charged on a mixture of methodologies that include quarterly in arrears based upon the market value at the end of the quarter, quarterly based on the average daily balance, or monthly. Receivable balances from contracts with customers are included in the fees receivable line in the Condensed Consolidated Statement of Financial Position. There were no write-offs of such fees receivable as of September 30, 2023, and December 31, 2022. Our FOS business is also included in this line item. FOS fees are generally structured to reflect an annual agreed upon fee or they can be structured on a project/time-based fee. FOS fees are typically billed quarterly in arrears. We also generate FOS project/time-based fees arising from accounting, administration fees, set up, the Foreign Account Tax Compliance Act (“FATCA”), and other non-investment advisory services. Incentive Fees The Company is entitled to incentive fees if targeted returns have been achieved in accordance with customer contracts. Incentive fees are calculated using a percentage of net profit from the amount the customers earn. Incentive fees are variable consideration that is generally calculated as applicable to the contract with the customer. We recognize our incentive fees when it is no longer probable that a significant reversal of revenue will occur. Our incentive fees are not subject to clawback provisions. Distributions from Investments The Company has equity interests in three entities pursuant to which it is entitled to distributions based on the terms of the respective arrangements. Distributions from each investment will be recorded upon receipt of the distribution. These distributions are recurring under investment agreements and are structured as either a profit or revenue share of the investment’s management and incentive fees. The Company generates arrangement fees in its co-investment division by arranging private debt or equity financing, generally in connection with an acquisition or an investment. Arrangement fees are typically 50 to 100 basis points of equity value contributed into a transaction. Acquisition fees are typically payable where there are no agency fees or where there is an off-market transaction sourced by the team. Such acquisition fees are usually in the range of 50 to 100 basis points of the purchase price of the relevant acquisition. The equity structures are long-term ( five (e) Cash and Cash Equivalents Cash and cash equivalents primarily consist of cash and money market funds. Cash balances maintained by consolidated VIEs are not considered legally restricted and are included in cash and cash equivalents on the Condensed Consolidated Statement of Financial Position. Cash was held across our US and international markets. A majority of cash in the U.S. was held in checking accounts within the credit facility bank group, including at a major global financial institution which management believes is creditworthy. (f) Restricted Cash and Cash Equivalents Restricted cash and cash equivalents consist of balances that are restricted as to withdrawal or usage. As of September 30, 2023 restricted cash and cash equivalents amounted to $3.4 million and are included in the line item Cash and cash equivalents on the Condensed Consolidated Statement of Financial Position. These amounts represent the level of liquidity to be maintained by Company’s certain subsidiaries to meet regulatory requirements. Failing to meet the requirement could lead to censure, fines and ultimately a loss of license. (g) Compensation and Employee Benefits Cash-Based Compensation Compensation and benefits consist of salaries, bonuses, commissions, benefits and payroll taxes. Compensation is accrued over the related service period. Equity-Based Compensation Equity-based compensation awards are reviewed to determine whether such awards are equity-classified or liability-classified. Compensation expense related to equity-classified awards is equal to their grant-date fair value and generally recognized on a straight-line basis over the awards’ requisite service period. When certain settlement features require an award to be liability-classified, compensation expense is recognized over the service period, and such amount is adjusted at each statement of financial position date through the settlement date to the then current fair value of such award. The Company recognizes equity-based award forfeitures in the period they occur as a reversal of previously recognized compensation expense. The reduction in compensation expense is determined based on the specific awards forfeited during that period. Furthermore, the Company recognizes all excess tax benefits and deficiencies as income tax benefit or expense in the Condensed Consolidated Statement of Operations. (h) Foreign Currency and Transactions The Company has multiple functional currencies across various consolidated entities. All functional currencies that are not the U.S. dollar are converted upon consolidation at the reporting date. Monetary assets and liabilities denominated in foreign currency are remeasured into U.S. dollars at the closing rates of exchange on the date of the Condensed Consolidated Statement of Financial Position. Non-monetary assets and liabilities denominated in foreign currencies are remeasured into U.S. dollars using the historical exchange rate. The profit or loss arising from foreign currency transactions is remeasured using the rate in effect on the date of the relevant transaction. Gains and losses on transactions denominated in foreign currencies due to changes in exchange rates are recorded within Foreign currency translation adjustments. Gains and losses on certain financing transactions which the Company intends to repay in the foreseeable future are recorded in net income. (i) Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC 740. Under this method, deferred tax assets and liabilities are determined based on differences between the condensed consolidated financial statement carrying amounts and tax bases of assets and liabilities and operating loss and tax credit carryforwards and are measured using the enacted tax rates that are expected to be in effect when the differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the Condensed Consolidated Statement of Operations in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to an amount that, in the opinion of management, is more likely than not to be realized, meaning the likelihood of realization is greater than 50%. The Company accounts for uncertain tax positions by reporting a liability for unrecognizable tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. (j) Other assets Other assets include prepaid expenses, miscellaneous receivables, current income taxes receivable, fixed assets, and software licenses. The Company amortizes assets over their respective useful lives, as applicable. (k) Investments Investments in Debt Securities. The Company classifies debt investments as held-to-maturity or trading based on the Company’s intent and ability to hold the debt security to maturity or its intent to sell the security. The Company does not have any held-to-maturity debt investments. Trading securities are those investments that are purchased principally for the purpose of selling them in the near term. Trading securities are carried at fair value on the Condensed Consolidated Statement of Financial Position with changes in fair value recorded in nonoperating income (expense) on the Condensed Consolidated Statement of Operations. Investments in Equity Securities . Equity securities are generally carried at fair value on the Condensed Consolidated Statement of Financial Position in accordance with ASC 321, “Investments – Equity Securities.” Changes in fair value are recorded in net gains (losses) in the Condensed Consolidated Statement of Operations. Equity Method . The Company applies the equity method of accounting for equity investments where the Company does not consolidate the investee but can exert significant influence over the financial and operating policies of the investee. The evaluation of whether the Company exerts control or significant influence over the financial and operational policies of its investees is based on the facts and circumstances surrounding each individual investment. The Company’s share of the investee’s underlying net income or loss is recorded as net gain (loss) on investments within current period earnings. The Company’s share of net income of the investee is recorded based upon the most current information available at the time, which may precede the date of the Condensed Consolidated Statement of Financial Position. Due to the nature and size of its investees, the Company has adopted a lag in reporting for certain equity method investees for which the Company cannot reliably obtain financial information on a regular basis. Distributions received reduce the Company’s carrying value of the investee and the cost basis if deemed to be a return of capital. For certain investments, the Company may apply the alternative fair value option to the investment at initial measurement. The fair value measurement of investments in which the option is elected will be measured in accordance with ASC 825. For equity method investments and nonmarketable investments, impairment evaluation considers qualitative factors, including the financial conditions and specific events related to an investee, which may indicate the fair value of the investment is less than the carrying value. For held-to-maturity investments, impairment is evaluated using market values, when available, or the expected cash flows of the investment. (l) Leases The Company accounts for its leases in accordance with ASC 842, Leases and recognizes a lease liability and right-of-use asset in the Condensed Consolidated Statement of Financial Position for contracts that it determines are leases or contain a lease. The Company evaluates leases at their inception to determine if they are to be accounted for as an operating lease or a finance lease. A lease is accounted for as a finance lease if it meets one of the following five criteria: (i) the lease has a purchase option that is reasonably certain of being exercised, (ii) the present value of the future cash flows is substantially all of the fair market value of the underlying asset, (iii) the lease term is for a significant portion of the remaining economic life of the underlying asset, (iv) the title to the underlying asset transfers at the end of the lease term, or (v) if the underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the term. Leases that do not meet the finance lease criteria are accounted for as an operating lease. At the inception of a finance lease, an asset and finance lease obligation are recorded at an amount equal to the lesser of the present value of the minimum lease payments and the property’s fair market value. Finance lease obligations are classified as either current or long-term based on the due dates of future lease payments, net of interest. The Company’s lease portfolio primarily consists of operating leases for office space in various countries around the world. The Company also has operating leases for office equipment and vehicles, which are not significant. The Company does not separate non-lease components from lease components for its office space and equipment operating leases and instead accounts for each separate lease component and its associated non-lease component as a single lease component. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the leases. The Company’s right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of lease payments over the lease term. Lease right-of-use assets include initial direct costs incurred by the Company and are presented net of deferred rent and lease incentives. Absent an implicit interest rate in the lease, the Company uses its incremental borrowing rate, adjusted for the effects of collateralization, based on the information available at commencement in determining the present value of lease payments. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease right-of-use assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company does not recognize a lease liability or right-of-use asset on the balance for short-term leases. Instead, the Company recognizes short-term lease payments as an expense on a straight-line basis over the lease term. A short-term lease is defined as a lease that, at the commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. When determining whether a lease qualifies as a short-term lease, the Company evaluates the lease term and the purchase option in the same manner as all other leases. (m) Intangible assets other than goodwill, net The Company recognized certain finite-lived intangible assets as a result of the Business Combination. The Company’s finite-lived intangible assets consist of Trade Names, Customer Relationships, Investment Management Agreements, and Backlog. Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives. The Company tests finite-lived intangible assets for impairment if certain events occur or circumstances change indicating that the carrying amount of the intangible asset may not be recoverable. The Company evaluates impairment by comparing the estimated fair value attributable to the intangible asset with its carrying amount. If an impairment exists, the Company adjusts the carrying value to equal the fair value by taking a charge through earnings. The Company also recognized certain indefinite-lived intangible assets as a result of the Business Combination consisting of certain investment management agreements. These indefinite-lived intangibles are not subject to amortization, but are evaluated for impairment at least annually. In assessing its indefinite-lived intangible assets for impairment, the Company has the option to first perform a qualitative assessment to determine whether events or circumstances exist that lead to a determination that it is unlikely that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If the Company determines that it is unlikely that the fair value of an indefinite-lived intangible asset is less than its carrying amount, the Company is not required to perform any additional tests in assessing the asset for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform a quantitative analysis to determine if the fair value of an indefinite-lived intangible asset is less than its carrying value. If through this quantitative analysis the Company determines the fair value of an indefinite-lived intangible asset exceeds its carrying amount, the indefinite-lived intangible asset is considered not to be impaired. If the Company concludes that the fair value of an indefinite-lived intangible asset is less than its carrying value, an impairment loss will be recognized for the amount by which the carrying amount exceeds the indefinite-lived intangible asset’s fair value. (n) Goodwill Goodwill represents the excess of the purchase price in a business combination over the fair value of the tangible and intangible assets acquired and the liabilities assumed. Under ASC 350, Intangibles—Goodwill and Other , goodwill is not amortized, but rather is subject to an annual impairment test. Goodwill represents the excess of consideration over identifiable net assets of an acquired business. Goodwill is allocated at a reporting unit level. The Company has two reporting units, Asset Management and Wealth Management, and tests goodwill annually for impairment at each reporting unit. If, after assessing qualitative factors, the Company believes that it is more-likely-than-not that the fair value of the reporting unit inclusive of goodwill is less than its carrying amount, the Company will perform a quantitative assessment to determine whether an impairment exists. If an impairment exists, the Company adjusts the carrying value of goodwill so that the carrying value of the reporting unit is equal to its fair value by taking a charge through earnings. The Company also tests goodwill for impairment in other periods if an event occurs or circumstances change such that it is more-likely-than-not to reduce the fair value of the reporting unit below its carrying amount. As of September 30, 2023, the Company recognized goodwill impairment charges of $153.6 million for the Asset Management segment in Impairment loss on goodwill and intangible assets in the Condensed Consolidated Statement of Operations. The Company concluded that the estimated fair value of the Wealth Management reporting unit was greater than its carrying value, and as such, no impairment charge was required. See Note 13 (Goodwill, net). (o) Fixed Assets, Net Fixed assets are recorded at cost, less accumulated depreciation and amortization, and are included in the “Other assets” line item in the Company’s Condensed Consolidated Statement of Financial Position. Fixed assets are depreciated or amortized on a straight-line basis, with the corresponding depreciation and amortization expense included within general, administrative and other expenses in the Company’s Condensed Consolidated Statement of Operations. The estimated useful life for leasehold improvements is the lesser of the remaining lease term and the life of the asset, while other fixed assets are generally depreciated over a period of two (p) Debt Obligations, Net The Company’s debt obligations are recorded at amortized cost, net of any debt issuance costs, discounts and premiums. Debt issuances costs are deferred and along with discounts and premiums are amortized to interest expense in the Condensed Consolidated Statement of Operations over the life of the related debt instrument using the effective interest method. Unamortized debt issuance costs, discounts and premiums are written off to net losses on retirement of debt in the Condensed Consolidated Statement of Operations when the Company prepays borrowings prior to maturity. (q) Tax Receivable Agreement The TRA liability represents amounts payable to certain pre-Business Combination equity holders of the Company. The portion of the TRA liability related to the Business Combination is deemed contingent consideration payable to the previous owners and is carried at fair value, with changes in fair value reported within other gain (loss) in the Condensed Consolidated Statement of Operations. Future exchanges of Class B Units for shares of Class A Common Stock may increase the TRA liability. Those increases will be carried at a value equal to the expected future payments due under the TRA. On August 31, 2023, holders of shares of Class B Common Stock exchanged a portion of such Class B Units to the Company, in exchange for shares of Class A Common Stock on a 1:1 basis totaling an amount equal to $7.31 multiplied by the total number of shares of Class B Common Stock exchanged at the time of the transaction. For future increases due to exchanges the Company will record an initial estimate of future payments under the TRA portion as a decrease to additional paid-in capital in the Condensed Consolidated Statement of Financial Position. Subsequent adjustments to the liability for future payments under the TRA related to changes in estimated future tax rates or state income tax apportionment are recognized through current period earnings in the Condensed Consolidated Statement of Operations. (r) Warrant Liability The Company evaluated the Warrants in accordance with ASC 815-40 and concluded that a provision in the warrant agreement related to certain tender or exchange offers precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative, the Warrants are recorded as derivative liabilities on the balance sheet and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in Other Income/(Expenses) in the Condensed Consolidated Statement of Operations in the period of change. Prior to the Business Combination the Sponsor held private warrants that were contributed to the Company and legally cancelled. The contribution and cancellation of these warrants resulted in derecognition of the private warrants and accounted for in additional paid in capital as of January 3, 2023. The Company subsequently issued new warrants with terms identical to those of the public warrants to the Target Companies’ selling shareholders classified as derivative liabilities. On June 7, 2023, the Company closed an offer and consent solicitation and entered into a warrant amendment, pursuant to which the remaining Warrants were exchanged. In total, the Warrants were exchanged for approximately 4,962,221 shares of Class A Common Stock. See Note 1 (Description of the Business). Following the exchange, none of the Warrants remain outstanding as of September 30, 2023. (s) Business Combination Earn-out Liability The Business Comb

Business Combination and Asset Acquisition [Abstract]
Business Combinations and Divestitures	Business Combinations and Divestitures On January 3, 2023, the Company entered into the Business Combination described in Note 1 (Description of the Business). The primary purpose of the Business Combination was to combine established high-growth companies that can benefit from access to capital and public markets and continue value-creation by management. The Business Combination is a forward merger and is accounted for using the acquisition method of accounting. The Company is the accounting acquirer and Umbrella, including the Target Companies, is the accounting acquiree. The Company has been determined to be the accounting acquirer because Umbrella meets the definition of a VIE, and the Company is the primary beneficiary of Umbrella. ASC 805 requires the primary beneficiary of a VIE to be identified as the accounting acquirer. The Company is the primary beneficiary because it controls all activities of Umbrella, and the non-managing members of Umbrella do not have substantive kick-out or participating rights. The Business Combination met the requirements to be considered a business combination under ASC 805. The assets and liabilities acquired from the Target Companies, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s condensed consolidated financial statements from the date of acquisition. The Company has allocated the purchase price to the tangible and identifiable intangible assets based on their estimated fair market values at the acquisition date as required under ASC 805. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets was recorded as goodwill and is deductible for tax purposes. The Business Combination resulted in the Company acquiring 51% of the equity interests of Umbrella which holds 100% of the equity interests of Alvarium, TWMH, and TIG. The remainder of Umbrella is held by the historical equity holders of TWMH and TIG through their ownership of Class B Units, which are presented as non-controlling interest on the Company’s Condensed Consolidated Statement of Financial Position. As a result of the Business Combination, Umbrella, which represents substantially all of the economic activity of the Company, became a subsidiary of the Company. Since the Company is the sole managing member of Umbrella following the Business Combination, the Class B Units held by the former equity holders of TWMH and TIG are classified as non-controlling interests in the Company’s financial statements. An allocation of net income or loss representing the percentage of ownership of Umbrella not controlled by the Company will be attributed to the non-controlling interests in the Company’s Condensed Consolidated Statement of Operations. Each Class B Unit of Umbrella is paired with a share of Class B Common Stock (collectively, the “Paired Interests”). Pursuant to the Umbrella LLC Agreement, a Paired Interest is exchangeable on certain dates designated by the Company for a share of Class A Common Stock on a one-for-one basis, subject to equitable adjustments for stock splits, stock dividends and reclassifications. As the holder exchanges the Paired Interests pursuant to the Umbrella LLC Agreement, the shares of Class B Common Stock included in the Paired Interests will automatically be canceled and the Class B Common Units included in the Paired Interests shall be automatically transferred to the Company and converted into and become an equal number of Class A Common Units in Umbrella. Alternatively, if approved by the disinterested members of the board of directors of the Company, such Class B Common Stock can be settled in cash funded from the proceeds of a private sale or a public offering of Class A Common Stock. The Sponsor, in connection with the Business Combination, purchased 8,625,000 shares of Class B Common Stock (the “Founder Shares”) for $25,000 (approximately $0.03 per share). These shares had no value until the Business Combination completed. At this point, the Founder Shares automatically converted into Class A Common Stock. This conversion was solely contingent upon the completion of the Business Combination and did not include any future service requirements. As such, this cost of 8,625,000 shares at $10.33 per share for $89.1 million will be presented “on the line” and is not reflected in either predecessor or successor financial statement periods. “On the line” describes those expenses triggered by the consummation of a business combination that are not recognized in the Condensed Consolidated Statement of Operations as they are not directly attributable to either period but instead were contingent on the Business Combination. As part of the Business Combination, the Company incurred $17.8 million of acquisition-related costs during the three months ended March 31, 2023 which are included predominantly in the “Professional fees” line in the Condensed Consolidated Statements of Operations. The Predecessor incurred $1.0 million of acquisition-related costs during the three months ended March 31, 2022. In addition, the Company incurred $4.6 million of debt issuance costs related to debt issued to finance the Business Combination. Of the total debt issuance costs, $1.8 million is related to the Term Loan and drawn amount of the Revolver and is recorded as an offset to the “Debt, net of unamortized deferred financing cost” line item of the Condensed Consolidated Statement of Financial Position. $2.8 million of the debt issuance costs related to the undrawn amount of the Revolver were recorded in the “Other assets” line item of the Condensed Consolidated Statements of Financial Position. The Business Combination was accounted for using the acquisition method of accounting, and the fair value of the total purchase consideration transferred was $1,071.1 million. Included in total purchase consideration is contingent consideration of $85.1 million, which is payable to the selling shareholders upon achievement of certain volume-weighted average price targets for the shares of Class A Common Stock or upon a change of control of the Company occurring between the Closing Date and the fifth anniversary of the Closing Date. The contingent consideration was measured at fair value at the acquisition date and recorded as a liability in the “Earn-out liability” line of the Condensed Consolidated Statement of Financial Position. See Note 2 (Summary of Significant Accounting Policies) for additional information. (Dollars in Thousands) Amount Cash consideration $ 99,999 Equity consideration: Class A $ 294,159 Class B $ 573,205 Warrants $ 4,896 Earn-out consideration $ 85,097 Tax Receivable Agreement $ 13,000 Payment of assumed liabilities $ 760 Total purchase consideration transferred $ 1,071,116 The consideration transferred is subject to customary closing adjustments in the post-combination period. While the valuation of consideration transferred is substantially completed, fair value estimates related to the consideration transferred are subject to adjustment for up to one year after the closing date of the acquisition as additional information becomes available. Valuations subject to adjustment include, but are not limited to, the Tax Receivable Agreement and Business Combination Earn-out consideration as management continues to review the estimated fair values and evaluate the assumed tax position. When the valuation is final, any changes to the preliminary valuation of consideration transferred could result in adjustments to identified intangibles and goodwill. The fair values of consideration transferred is expected to be finalized during the remeasurement period, which ends on December 31, 2023. During the period from January 3, 2023 to September 30, 2023, there were no measurement period adjustments made to purchase consideration transferred. The following table sets forth the fair values of the assets acquired and liabilities assumed in connection with the Business Combination (in thousands): (Dollars in Thousands) Business Cash and cash equivalents $ 24,023 Management/advisory fees receivable 42,494 Investments at fair value 148,674 Equity method investments 42,307 Property, plant and equipment 3,996 Intangible assets 520,161 Goodwill 543,956 Operating lease right-of-use assets 28,487 Other assets 47,251 Total Assets Acquired $ 1,401,349 Accounts payable and accrued expenses 75,647 Accrued compensation and profit sharing 25,051 Accrued member distributions payable 12,803 Delayed share purchase agreement 1,818 Earn-in consideration payable 1,519 Operating lease liabilities 29,047 Debt 124,533 Deferred tax liability, net 43,906 Other liabilities 15,149 Total Liabilities Assumed $ 329,473 Total Assets Acquired and Liabilities Assumed 1,071,876 Non-controlling interest in subsidiaries (760) $ 1,071,116 For the period from January 3, 2023 to September 30, 2023, cash and cash equivalents at the beginning of the period of $194.1 million included the proceeds from the PIPE Investors related to the private placement issuances, remaining cash held in the trust account, and the beginning balance sheet cash from each of Alvarium, TIG, and TWMH. While the valuation of acquired assets and liabilities is substantially complete, fair value estimates are subject to adjustment for up to one year after the closing date of the acquisition as additional information becomes available. Valuations subject to adjustment include, but are not limited to, equity method investments, intangible assets, and the Tax Receivable Agreement liability, as management continues to review the estimated fair values and evaluate the assumed tax position. The fair values of assets acquired and liabilities assumed is expected to be finalized during the measurement period, which ends no later than December 31, 2023. During the nine months ended September 30, 2023, the Company made certain measurement period adjustments to the preliminary purchase price allocation, which resulted in an increase to goodwill of $19.2 million. The increase in goodwill was due to a $21.6 million decrease in the fair value of acquired intangible assets, a $5.4 million decrease in the fair value of acquired equity method investments, offset by a $6.4 million decrease to deferred tax liabilities, a $0.8 million increase in Management/advisory fees receivable, a $0.3 million decrease in Other liabilities, a $0.2 million increase in Accounts payable and accrued expenses, and a $0.1 million increase in Other assets, that arose from the measurement period adjustments. Additionally, the Company made certain measurement period adjustments to the opening equity balance as a result of the Business Combination, which resulted in a decrease to opening additional paid-in capital of $1.3 million and an immaterial decrease to non-controlling interest in subsidiaries as of January 3, 2023. The measurement period adjustments were a result of the change in net assets described earlier. The fair values of assets acquired and liabilities assumed are expected to be finalized during the measurement period, which ends no later than December 31, 2023. There is no income statement impact of the measurement period adjustments during the period from July 1, 2023 to September 30, 2023, because the amortization expense relating to intangible assets was adjusted in the prior quarter, and equity method investments are reported on a lag basis. Fair Value of Net Assets Acquired and Intangibles With the exception of operating right-of-use assets and operating lease liabilities accounted for under Topic 842, in accordance with Accounting Standards Codification, or ASC 805, the assets and liabilities were recorded at their respective fair values as of January 3, 2023. The Company developed the fair value of intangible assets, which include trade names, customer relationships, investment management agreements, developed technology and backlog, using various techniques including discounted cash flow, relief from royalty, multi-period excess earnings, and a Monte Carlo simulation approach. The Company developed the fair value of equity method investments using various techniques including discounted cash flow and a guideline public company approach. The investments at fair value and earn-in consideration are carried at fair value and no adjustment was made. For all other major assets and liabilities acquired, the Company determined that book value approximated fair value. Goodwill is comprised of expected synergies for the combined operations and the assembled workforce acquired in the Business Combination, which does not qualify as a separately recognized intangible asset. Goodwill is allocated between the two reporting segments: Wealth Management and Asset Management. The initial goodwill allocation between Wealth Management and Asset Management at the acquisition date was $293.7 million and $250.2 million, respectively. Below is a summary of the intangible assets acquired in the Business Combination (in thousands): (Dollars in Thousands) Acquisition Date Estimated Life Trade Names $ 14,695 11.5 Customer Relationships 163,392 27.1 Investment Management Agreements (definite life) 94,575 18.4 Investment Management Agreements (indefinite life) 245,900 Indefinite Developed Technology 1,000 5 Backlog 599 0.5 Total Intangible Assets $ 520,161 The intangible assets acquired and subject to amortization have a weighted average useful life of 23.1 years. AL Wealth Partners Pte. Ltd. On April 6, 2023, (the “ALWP Acquisition Date”), the Company acquired all of the issued and outstanding ownership and membership interests of AL Wealth Partners Pte. Ltd. (“AL Wealth Partners”) pursuant to the terms of the share purchase agreement between the Company and AL Wealth Partners (the “ALWP Acquisition”). The primary purpose of the ALWP Acquisition is to acquire AL Wealth Partners’ extensive business within Southeast Asia to further expand the Company’s global operations. The ALWP Acquisition met the requirements to be considered a business combination under ASC 805. The assets and liabilities acquired from AL Wealth Partners, affected for preliminary adjustments to reflect the fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s condensed consolidated financial statements from the ALWP Acquisition Date. The Company has allocated the purchase price to the tangible and identifiable intangible assets and liabilities assumed based on their estimated fair market values at the ALWP Acquisition Date as required under ASC 805. The ALWP Acquisition was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $15.5 million, with the total amount paid in cash. The Company will make second and third payments to the sellers of AL Wealth Partners on the third and fifth anniversary of the ALWP Acquisition Date, respectively. Management has determined that these payments are compensatory in nature and will be treated as future compensation expense. There is no contingent consideration as part of the ALWP Acquisition. The Company incurred $0.3 million of direct acquisition-related expenses, which are recognized in the Professional fees line item of the Condensed Consolidated Statement of Operations. The following table sets forth the fair values of the assets acquired and liabilities assumed in connection with the ALWP Acquisition: (Dollars in Thousands) ALWP Acquisition Date Fair Value Cash and cash equivalents $ 1,092 Management/advisory fees receivable 1,952 Property, plant and equipment 654 Intangible assets 12,300 Goodwill 987 Operating lease right-of-use assets 1,048 Other assets 484 Total Assets Acquired 18,517 Accounts payable and accrued expenses 358 Operating lease liabilities 1,048 Other liabilities 1,581 Total Liabilities Assumed $ 2,987 Total Assets Acquired and Liabilities Assumed $ 15,530 The purchase price allocation is preliminary and subject to change during the measurement period, which is not to exceed one year from the ALWP Acquisition Date. During the period ended September 30, 2023, there were no measurement period adjustments made to the assets acquired or liabilities assumed. When the valuation is final, changes to the valuation of acquired assets and liabilities could result in adjustments to identified intangibles and goodwill. Fair Value of Net Assets Acquired and Intangibles Goodwill is comprised of expected synergies for the combined operations, including employees and customer relationships acquired in a business combination. The total amount of goodwill arising in the transaction was allocated to the Company’s Wealth Management segment. The components of goodwill do not qualify as a separately recognized intangible asset. The Company will test for impairment annually to determine changes in goodwill at the Wealth Management reporting unit. The Company will also test goodwill for impairment in other periods if an event occurs or circumstances change such that it is more-likely-than-not to reduce the fair value of the reporting unit below its carrying amount. Below is a summary of the intangible assets acquired in the ALWP Acquisition: (Dollars in Thousands) ALWP Acquisition Date Fair Value Estimated Life (Years) Customer Relationships $ 12,300 10 Total Intangible Assets $ 12,300 The fair value for customer relationships was determined using the multi-period excess earnings method. The intangible assets are subject to amortization over a useful life of 10 years. The results of operations for the ALWP Acquisition have been included in the Company’s Condensed Consolidated Financial Statements from the date of ALWP Acquisition. The ALWP Acquisition did not have a material impact on the Company’s Condensed Consolidated Financial Statements, and, therefore, historical and pro forma disclosures have not been presented. Alvarium Investment Managers (Suisse) SA On August 2, 2023, (the “AIMS Acquisition Date”), the Company acquired the remaining 70% of the issued and outstanding ownership and membership interests of Alvarium Investment Managers (Suisse) SA (“AIMS”), increasing its interest from 30% to 100% (the “AIMS Acquisition”). The AIMS Acquisition met the requirements to be considered a business combination under ASC 805. The assets and liabilities acquired from AIMS, affected for preliminary adjustments to reflect the fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s condensed consolidated financial statements from the AIMS Acquisition Date. The Company has allocated the purchase price to the tangible and identifiable intangible assets and liabilities assumed based on their estimated fair market values at the AIMS Acquisition Date as required under ASC 805. The AIMS Acquisition was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $16.8 million. The total purchase consideration transferred consists of cash consideration, equity consideration, deferred cash consideration, earn-out consideration, and the payment of assumed liabilities. The total purchase consideration consists of the following amounts: (Dollars in Thousands) AIMS Amount Initial Cash consideration $ 5,711 Equity consideration 1,459 Deferred cash consideration 6,695 Earn-out consideration 2,721 Payment of assumed liabilities 168 Total purchase consideration transferred $ 16,754 The deferred cash consideration is payable no later than September 30, 2024 and the earn-out consideration is payable no later than December 31, 2024. At the AIMS Acquisition Date, as required by ASC 805, the Company’s existing 30% equity interest in AIMS, which was previously recognized as an equity method investment, was revalued to reflect the fair value at this date. The fair value of this existing equity method investment was $7.2 million. This change in fair value has resulted in a gain of $1.7 million being recognized, this amount has been recognized in the Gain (loss) on investments line of the Condensed Consolidated Statement of Operations. The Company incurred $0.01 million of direct acquisition-related expenses, which are recognized in the Professional fees line item of the Condensed Consolidated Statement of Operations. The following table sets forth the fair values of the assets acquired and liabilities assumed in connection with the AIMS business combination: (Dollars in Thousands) AIMS Acquisition Date Fair Value Cash and cash equivalents $ 1,401 Management/advisory fees receivable 1,057 Equity Method investments 57 Intangible assets 9,679 Goodwill 14,299 Operating lease right-of-use assets 298 Other assets 323 Total Assets Acquired 27,114 Accounts payable and accrued expenses 784 Operating lease liabilities 298 Other liabilities 2,097 Total Liabilities Assumed $ 3,179 Total Assets Acquired and Liabilities Assumed $ 23,935 The purchase price allocation is preliminary and subject to change during the measurement period, which is not to exceed one year from the AIMS Acquisition Date.

Prior to the AIMS Acquisition Date, the results of AIMS were included as a 30% held equity method investment. Alvarium Home REIT Advisors Ltd On June 30, 2023, the Company entered into a series of agreements that resulted in the deconsolidation of AHRA from the Asset Management segment with immediate effect. The agreements removed ARE’s potential controlling voting rights in AHRA (previously ascertainable on the exercise of the option), and terminated other residual contractual relationships between AHRA and ARE. As a result, these agreements removed AlTi’s control of AHRA from an accounting perspective. AHRA’s results are included in the Company’s Condensed Consolidated Statement of Operations for the period from January 3, 2023 to June 30, 2023, and its accounts were removed from the Consolidated Statement of Financial Position as of June 30, 2023. The deconsolidation resulted in an intangible asset impairment charge of $29.4 million, which is recorded in Impairment loss on goodwill and intangible assets in the Condensed Consolidated Statement of Operations. Assets managed by AHRA, however, have been excluded from the Company’s AUM/AUA metrics since January 3, 2023. Assets Held for Sale FOS is a part of the Company’s international wealth management business. The Company met the criteria required to classify this expected disposal as an asset held for sale.

Equity-Based Compensation and Earn-in Expenses	Equity-Based Compensation and Earn-in Expenses In connection with the Business Combination, certain of TWMH’s restricted units vested and the Company granted fully vested shares to Alvarium’s employees, resulting in compensation expense of $4.2 million and $24.6 million, respectively, during the period from January 3, 2023 to September 30, 2023. The $24.6 million consisted of $21.0 million related to the acceleration of 2.1 million of earn-out shares at closing and $3.6 million for 360,485 shares related to another transaction completed in contemplation of and for the benefit of the acquirer under Topic 805. None of these stock awards were outstanding after the Business Combination. Upon completion of the Business Combination, the Company issued 60,800 shares of Class A Common Stock to employees of the Company. These awards vested in full immediately and had a fair value of $10.00 per share, resulting in compensation expense of $0.6 million during the period from January 3, 2023 to September 30, 2023. In connection with the Business Combination, the Company granted 65,554 shares of Class A Common Stock to its board of directors on March 23, 2023. These awards vest over an approximate nine On May 31, 2023, the Company granted 4,693,621 shares of Class A Common Stock with a fair value of $4.35 per share to employees as restricted units, vesting over a three 2023, the Company granted 107,263 shares of Class A Common Stock with fair values representative of buy-out equity awards to employees as restricted units, vesting generally over a one three In connection with TWMH’s historical acquisition of Holbein Partners, LLP (“Holbein”), certain employees of Holbein are entitled to receive a combination of cash and shares of the Company based on Holbein revenues in 2023 and 2024 (the “Holbein Earn-Ins”). The Holbein Earn-Ins were measured at fair value using estimates of future revenues as of the closing date. The earn-ins are expected to be paid in a combination of 50% cash and 50% in shares of the Company’s Class A Common Stock on the second and third anniversaries of the closing date of January 7, 2022. On July 14, 2023, the Company amended the Holbein purchase agreement related to the Holbein acquisition. The amendment crystallized the contingent earn-in consideration amount by replacing the valuation of the Holbein Earn-Ins consideration of an estimate of future revenue. Additionally, the first payment date and second payment date are agreed as April 1, 2024 and April 1, 2025, respectively, replacing the original share purchase agreement payment dates of 10 business days after the second and third anniversary of the acquisition of Holbein. The agreed upon first and second date payments are $7.1 million and $8.9 million, respectively. The selling shareholders remain required to maintain certain service agreements to receive the compensatory Holbein Earn-ins. The Company recognized an expense for the earn-ins of $2.4 million and $0.7 million for the period from July 1, 2023 to September 30, 2023 and the period from July 1, 2022 to September 30, 2022, respectively, and $4.5 million and $2.2 million for the period from January 3, 2023 to September 30, 2023 and the period from January 1, 2022 to September 30, 2022, respectively, which is included in Compensation and employee benefits in the Condensed Consolidated Statement of Operations. Separate from the compensatory Holbein Earn-Ins, the Holbein acquisition consideration included contingent consideration that was measured at fair value using estimates of future revenues as of the closing date. The acquisition consideration was also amended to crystallize the non-compensatory earn-in amount and follows the same fact pattern as the above-described amendment for the compensatory earn-ins. This contingent consideration is recorded as a liability of $1.7 million as of September 30, 2023 and $1.5 million as of December 31, 2022 in the “Earn-in consideration payable” line of the Condensed Consolidated Statement of Financial Condition. In connection with TWMH’s historical acquisition of TIH, the Delayed Share Purchase Agreement (“TIH SPA”) was amended on July 28, 2023. The TIH SPA was amended to include the Company’s Class A Common Stock as part of the purchase price. On August 1, 2023, the Company granted 152,930 shares of Class A Common Stock with a fair value of $7.70 per share under the terms of the TIH SPA amendment. The amendment to the purchase price is compensatory in nature. The Company recognized an expense for the TIH SPA of $1.2 million for both the periods from July 1, 2023 to September 30, 2023 and from January 3, 2023 to September 30, 2023, which is included in Compensation and employee benefits in the Condensed Consolidated Statement of Operations.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe computation of the effective tax rate and provision at each interim period requires the use of certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income that is subject to tax, permanent differences between the Company’s GAAP earnings and taxable income, and the likelihood of recovering deferred tax assets existing as of the balance sheet date. The estimates used to compute the provision for income taxes may change throughout the year as new events occur, additional information is obtained or as tax laws and regulations change. Accordingly, the effective tax rate for future interim periods may vary materially. The Company is a domestic corporation for U.S. federal income tax purposes and is subject to U.S. federal and state and local corporate-level income taxes on its share of taxable income from the Umbrella Partnership. The Umbrella Partnership is a partnership for U.S. federal income tax purposes and a taxable entity for certain state and local taxes, such as New York City and Connecticut unincorporated business tax (“UBT”). Further, the Company’s income tax provision and related income tax assets and liabilities are based on, among other things, an estimate of the impact of exchanges of Warrants and Class B Units for shares of Class A Common Stock, inclusive of an analysis of tax basis and state tax implications of the Umbrella Partnership and its underlying assets and liabilities. The Company’s estimate is based on the most recent information available. The tax basis and state impact of the Umbrella Partnership and its underlying assets and liabilities are based on estimates subject to finalization of the Company’s tax returns. The Company had an effective tax rate of 1.0% and 5.1% for the periods from July 1, 2023 to September 30, 2023 and from January 3, 2023 to September 30, 2023, respectively, and 13.3% and 25.9% for the three and nine months ended September 30, 2022, respectively. The effective tax rates differed from the statutory rate primarily due to the portion of income allocated to noncontrolling interests, nondeductible compensation and state and local taxes. The Company regularly evaluates the realizability of its deferred tax asset and may recognize or adjust any valuation allowance when it is more-likely-than-not that all or a portion of the deferred tax asset may not be realized. As of September 30, 2023, the Company has recorded valuation allowances against a portion of its deferred tax assets generated by its subsidiaries in the United Kingdom. The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the tax years that remain open under the statute of limitations may be subject to examinations by the appropriate tax authorities. As of September 30, 2023 and September 30, 2022, the Company has evaluated its tax filing positions and has not recorded a reserve for unrecognized tax benefits.

Fair Value Disclosures

Fair Value Disclosures	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures The Company classifies its fair value measurements using a three-tiered fair value hierarchy. The basis of the tiers is dependent upon the various “inputs” used to determine the fair value of the Company’s assets and liabilities. Fair value is considered the value using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Observable inputs are those that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the inputs market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The inputs are summarized in the three broad levels listed below: • Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. • Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. • Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. Level 2 Valuation Techniques The financial instruments classified within Level 2 of the fair value hierarchy is an interest rate swap. The valuation techniques used to value financial instruments classified within Level 2 of the fair value hierarchy are as follows: • The interest rate swap is valued based on observable values of underlying interest rates. Level 3 Valuation Techniques As the Company exercised significant judgement over unobservable inputs, the fair values of these financial instruments are considered Level 3 measurements: • The Company utilized a Monte Carlo simulation to measure the Business Combination Earn-out and TRA liabilities. This simulation uses rates to appropriately capture the risk associated with each obligation. The Company adjusts the liabilities to fair value each reporting period based on certain metrics within the respective agreements. Changes in fair value are recognized in Gain (loss) on earn-out liability in the Condensed Consolidated Statement of Operations and in Fair value of earn-out liability in the Condensed Consolidated Statement of Cash Flows in the period of change. Refer to the valuation methodologies table below for further analysis of level 3 valuations. • The Company utilized a Monte Carlo simulation to measure the earn-out liability associated with the acquisition of AIMS. The valuation of the AIMS earn-out liability captures the risk of the obligation through financial metrics adjusted for market risk. Changes in the fair value are recognized in other expense in the Condensed Consolidated Statement of Operations. Refer to the valuation methodologies table below for further analysis of level 3 valuations. • The fair value of the Earn-in consideration is based on expected future revenues discounted at the revenue discount rate less the risk-free rate of return. The Company adjusts the liabilities to fair value each reporting period based on certain metrics within the respective agreements. Changes in the fair value are recognized in other expense in the Condensed Consolidated Statement of Operations. Refer to the valuation methodologies table below for further analysis of level 3 valuations. • The Company utilized a Discounted Cash Flow simulation to determine the fair value of the External Strategic Managers. The discount rate selection for each investment was calibrated using the implied internal rate of return as of the original investment date, adjusted for certain market- and company-specific factors. The selected long-term growth rate for each investment was based on long-term GDP growth rates in the geographic locations of the underlying External Strategic Manager, with consideration for general growth in the asset management industry. The following is a summary categorization, as of September 30, 2023 and December 31, 2022, of the Company’s financial instruments based on the inputs utilized in determining the value of such financial instruments: Investments at fair value as of September 30, 2023 and December 31, 2022 are presented below: As of September 30, 2023 (Successor) Level 1 Level 2 Level 3 (Dollars in Thousands) Quoted Prices Observable Inputs Unobservable Inputs Total Assets: Mutual funds $ 51 $ — $ — $ 51 Exchange-traded funds 111 — — 111 Investments – External Strategic Managers — — 163,125 163,125 Investments – Affiliated Funds (1) — — — 1,373 Total $ 162 $ — $ 163,125 $ 164,660 Liabilities: Earn-out liability $ — $ — $ 45,549 $ 45,549 AIMS earn-out liability (2) — — 2,721 2,721 TRA liability (3) 3,711 — 14,331 18,042 Earn-in consideration payable 1,708 — — 1,708 Total $ 5,419 $ — $ 62,601 $ 68,020 (1) Investments in Affiliated Funds are measured at fair value using the net asset value (or its equivalent) practical expedient. The Company's investments in Affiliated Funds represent interests that do not trade in an active market and are valued using the NAV of each investment company as reported and without adjustment. The Company does not have any commitments to the Affiliated Funds and redemptions are permitted on a monthly basis and require 30 days’ notice. The strategies of the Affiliated Funds primarily focus on near-dated, hard catalyst events that typically involve hostile deals, proposals, minority interest buy-ins, leverage buyouts, activism, spin-offs, recapitalizations, and agreed upon deals. The investments held in the Affiliated Funds are primarily highly liquid and marketable securities. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Condensed Consolidated Statement of Financial Position.

In accordance with GAAP, certain equity method investees do not account for both their financial assets and liabilities under fair value measures; therefore, the Company’s investment in such equity method investees may not represent fair value. For the periods from July 1, 2023 to September 30, 2023 and from January 3, 2023 to September 30, 2023, the Company recognized $0.0 million and $0.3 million, respectively, of impairment on its equity method investments. Additionally, as part of the Business Combination, AlTi acquired the right to carried interest on several projects. These are held as assets at cost less impairment. We therefore assess for indicators of impairment every quarter, and as a result of a number of factors, namely market conditions, we recognized an impairment to these assets of $1.8 million and $3.6 million for the periods from July 1, 2023 to September 30,

Leases [Abstract]
Leases	Leases The Company adopted ASC 842 as of January 1, 2022, on a modified retrospective basis with no cumulative adjustment to equity as of the adoption date. The Company has presented financial results and applied its accounting policies for the period beginning January 1, 2022 under ASC 842 for the predecessor and successor periods. The Company elected to take the practical expedient to not separate lease and non-lease components as part of the adoption. Lease agreements entered into after the adoption of ASC 842 that include lease and non-lease components are accounted for as a single lease component. Since January 1, 2022, the Company’s operating leases, excluding those with terms less than 12 months, have been discounted and recorded as assets and liabilities on the Company’s Condensed Consolidated Statement of Financial Position. The Company primarily has non-cancellable operating leases for office spaces across various countries. We categorize leases as either operating or finance leases at the commencement date of the respective lease.

(Dollars in Thousands) Asset Management Wealth Management As of December 31, 2022 Beginning Balance Gross goodwill $ 263,429 $ 297,759 $ 22,185 Net goodwill: $ 263,429 $ 297,759 $ 22,185 Goodwill acquired during the period $ — $ 11,356 $ 3,279 Impairment charges (153,589) — — Measurement period adjustments (1,178) (376) — Currency translation and other adjustments (8,482) 513 — $ (163,249) $ 11,493 $ 3,279 Ending Balance Gross goodwill $ 100,180 $ 309,252 $ 25,464 Net goodwill $ 100,180 $ 309,252 $ 25,464 During the period from July 1, 2023 to September 30, 2023, the Company made certain measurement period adjustments to the preliminary purchase price allocation, which resulted in a decrease to goodwill of $1.5 million. See Note 3 (Business Combinations and Divestiture). Further, the Company evaluated as of September 30, 2023 whether circumstances existed, indicating that the fair value of its reporting units may have declined to an amount lower than the carrying value of goodwill recorded on its consolidated balance sheet as of that date. The Company considered a variety of factors, including the impact of prevailing market conditions, persistently high interest rates and uncertainties caused by inflation and certain world events as well as the recent actions taken by the Company to restructure and reposition certain of the businesses within its reporting units. Based on the evaluation of these factors, the Company concluded that triggering events had occurred during the period that required the Company to assess whether the goodwill allocated to its Asset Management segment was impaired. Accordingly, the Company performed a goodwill impairment test, which compared the estimated fair value of the Asset Management reporting unit to its carrying value. The Company utilized the discounted cash flow method under the income approach and the Guideline Public Company Method (“GPCM”) under the market approach, in equal weightings, in determining a fair value for the reporting unit. The results of the impairment test performed at September 30, 2023 indicated that the carrying value of the Asset Management reporting unit exceeded its estimated fair value by $153.6 million. Consequently, the Company recognized a goodwill impairment charge for this amount in the Condensed Consolidated Statement of Operations for the period ended September 30, 2023. The assumptions used in the discounted cash flow analyses require significant judgment, including judgment about appropriate growth rates and the amount and timing of expected future cash flows. The Company’s forecasted cash flows were based on its current assessment of the markets and on assumed growth rates expected as of the measurement date. The key assumptions used in the cash flows were revenue growth rates, operating expenses, gross margins, and discount rates that appropriately reflect the risks inherent in the cash flow streams. Under the GPCM approach, the significant assumptions include the consideration of stock price and financial metrics from guideline companies.

Debt, net of unamortized deferred financing cost	Debt, net of unamortized deferred financing cost The following table summarizes outstanding debt obligations of the Company as of September 30, 2023: As of September 30, 2023 (Successor) (Dollars in Thousands) Debt Outstanding Net Carrying Value (1) Fair Value (2) Credit Agreement Term Loans $ 96,250 $ 94,554 $ 96,250 Revolving Credit Facility 78,250 78,250 78,250 Total Debt $ 174,500 $ 172,804 $ 174,500 (1) Represents debt outstanding net of unamortized debt issuance costs. (2 ) The fair value of the Term Loans and Revolving Credit Facility approximates carrying value as of September 30, 2023 due to the recent issuance of the debt instruments. The fair value is categorized as Level 3 under ASC 820. Credit Agreement On January 3, 2023, the Company entered into a credit agreement (the “Credit Agreement”) with BMO Harris Bank N.A., as administrative agent, for a senior secured credit facility (the “BMO Credit Facility”) in an aggregate principal amount of $250.0 million, consisting of term loan commitments for an aggregate principal amount of $100.0 million (the “Term Loans”) and a revolving credit facility with commitments for an aggregate commitment amount of $150.0 million (the “Revolving Credit Facility”), with an accordion option to increase the revolving commitments an additional $75.0 million to $225.0 million total. Upon the Closing, the Company had initially acquired legacy debt obligations from its subsidiaries in the amount of $124.4 million. Subsequently, after the Closing, the Company obtained additional financing through the BMO Credit Facility from which proceeds from borrowings were used to repay outstanding debt obligations acquired through the transaction, and also for working capital and general corporate purposes, including, without limitation, permitted acquisitions. The Term Loans and Revolving Credit Facility bear interest at a rate per annum equal to, at the Company’s option, either (i) SOFR plus a margin based on the Company’s Total Leverage Ratio (as defined in the Credit Agreement) or (ii) the Base Rate (as defined in the Credit Agreement) plus a margin based on the Company’s Total Leverage Ratio. The margin ranges between 1.0% and 2.0% for base rate loans and between 2.0% and 3.0% for SOFR loans. The Company will pay a commitment fee based on the average daily unused portion of the commitments under the Revolving Credit Facility, a letter of credit fee equal to the margin then in effect with respect to the SOFR loans under the Revolving Credit Facility, a fronting fee and any customary documentary and processing charges for any letter of credit issued under the Credit Agreement. The Term Loan is subject to quarterly amortization payments and will mature on January 3, 2028. The Revolving Credit Facility will terminate on January 3, 2028. As of September 30, 2023, unfunded commitments on the Revolving Credit Facility amounted to $71.8 million, and the weighted-average interest rate the outstanding borrowings of this facility was 8.5%. As security for the Term Loans and Revolving Credit Facility, the borrower and the guarantors thereunder have pledged substantially all of their assets, subject to agreed-upon exclusions. The guarantor group consists of the Company’s U.S. and non-U.S. subsidiaries, subject to an agreed-upon materiality threshold. As of September 30, 2023, total outstanding debt, net of unamortized deferred financing costs amounted to $172.8 million. First Amendment to Credit Agreement On March 31, 2023 the Company executed the First Amendment to the Credit Agreement (the “First Amendment”). The First Amendment permits the Company to extend the time period for certain payments to be made that would have otherwise been restricted by the Credit Agreement. A copy of the First Amendment is included as Exhibit 10.1 to this Quarterly Report on Form 10-Q and incorporated herein by reference. Second Amendment to Credit Agreement On November 10, 2023, the Company entered into the Second Amendment to the Credit Agreement (“the Second Amendment”). The Second Amendment, among other things, temporarily amends, from the date of the amendment until effectively April 1, 2024, the following provisions of the Credit Agreement: • The aggregate commitment amount under the Revolving Credit Facility is reduced from $150.0 million to $110.0 million; • The financial covenants in the Credit Agreement are adjusted to allow for a higher Total Leverage Ratio and Modified Leverage Ratio as well as a lower Interest Coverage Ratio; • During the amendment period, cash proceeds from the issuance of any debt, (other than certain debt permitted under the Credit Agreement) and any equity securities issued by the Company are required to be used to repay amounts outstanding under the facility, first under the Term Loans until such Term Loans are repaid in full and then under the Revolving Credit Facility, until the Revolving Credit Facility is reduced to $50.0 million in the aggregate; and • Beginning after the end of the amendment period, certain clauses in the Credit Agreement that pertain to restricted payments are amended. A copy of the Second Amendment is included as Exhibit 10.2 to this Quarterly Report on Form 10-Q and incorporated herein by reference. The Company has initiated discussions with the administrative agent regarding potentially making further amendments to the Credit Agreement. The Company is evaluating various options in relation to the Credit Agreement, including to partially or fully repay the debt outstanding or to make further amendments to its terms. This evaluation is being made in connection with a broader review of the Company’s capital planning for the short to medium term, including its needs for sources of capital to complete acquisitions to facilitate growth, its business strategy as it pertains to how certain of its business activities are funded, as well more generally as to how it should optimize its capital structure. As required by accounting standards, the Company has performed an assessment based on its current operations and capital structure of its ability to generate sufficient cash flows to meet its financial obligations for one year subsequent to the financial statement issuance date, based on conditions known and reasonably knowable as of the financial statement issuance date. Management has performed this required assessment as of November 14, 2023, and believes there are sufficient funds available to support its ongoing business operations and continue as a going concern for at least the next 12 months. Management’s assessment is subject to known and unknown risks, uncertainties, assumptions, and changes in circumstances, many of which are beyond our control including the impact of the macroeconomic environment, and that are difficult to predict as to timing, extent, likelihood, and degree of occurrence, and that could cause actual results to differ from estimates and forecasts, potentially materially. Based upon the results of Management’s assessment, these interim unaudited consolidated financial statements have been prepared on a going concern basis. The interim unaudited consolidated financial statements do not include any adjustments that could result from the outcome of the aforementioned risks and uncertainties. The following tables summarize outstanding debt obligations of the Company as of December 31, 2022 : As of December 31, 2022 (Dollars in Thousands) Debt Outstanding Net Carrying Value (1) Term Loan $ 5,760 $ 5,760 Revolving Credit Facility 14,050 14,050 Promissory Notes 1,377 1,377 Total Debt $ 21,187 $ 21,187 (1) There were no unamortized debt issuance costs as of December 31, 2022.

Equity Method Investees The Company’s transactions with Equity Method Investees include receivables related to loans, fees, and expenses, which are presented in Other assets on the Condensed Consolidated Statement of Financial Condition, and payables related to loans, fees and expenses, which are presented in Accounts payable and accrued expenses and Other Liabilities on the Condensed Consolidated Statement of Financial Condition. For the period from January 3, 2023 to September 30, 2023, the Company recognized $0.5 million in Management/advisory fees, $2.7 million in Compensation and employee benefits, $(0.4) million in Other income/fees and $(32.6) thousand in Interest and dividend income (expense) from equity method investees on the Condensed Consolidated Statement of Operations. Tax Receivable Agreements On the Closing Date, the Company entered into the Tax Receivable Agreement. The TRA generally provides for certain payments and makes certain arrangements with respect to certain tax benefits to be derived by the Company and its subsidiaries as the result of the Business Combination and future exchanges by such TWMH Members, TIG GP Members and TIG MGMT Members of their Paired Interests for Class A Common Stock in accordance with the Umbrella LLC Agreement and the making of payments under the TRA. Pursuant to the terms of the TRA, the Company generally will pay an amount equal to 85% of the net tax benefit that it receives from such exchanges to the TWMH Members, the TIG GP Members and the TIG MGMT Members. The costs and expenses of administering the TRA will be borne 15% by the Company and 85% by the TWMH Members, the TIG GP Members and the TIG MGMT Members, or in certain instances, all or a portion of such 85% amount may be borne by Umbrella. The TRA is recognized on the Consolidated Statement of Financial Condition as the TRA Liability. The value of the TRA Liability was $18.0 million as of September 30, 2023. The Company carries $14.3 million of its TRA Liability at fair value, as it is contingent consideration from the Business Combination. The remaining portion related to the TRA exchange of $3.7 million is recorded at its carrying value. The Company recognized a gain of $0.8 million and a loss of $(1.3) million for the period from July 1, 2023 to September 30, 2023 and the period from January 3, 2023 to September 30, 2023, respectively, which is recorded in Gain (loss) on TRA in the Condensed Consolidated Statement of Operations. On August 31, 2023, holders of Class B Common Stock exchanged a portion of such Class B Units to the Company, in exchange for shares of Class A Common Stock on a 1 :1 basis totaling an amount equal to $7.31 multiplied by the total number of shares of Class B Common Stock exchanged at the time of the transaction. For the period from January 3, 2023 to September 30, 2023, the Company made tax payments on behalf of and cash distributions to Class B Units holders related to the TRA of $1.0 million.

The earn-out shares are precluded from being considered indexed to the Company's own stock and are recognized as a liability at fair value with changes in fair value recognized in earnings. As of September 30, 2023, the fair value of the Business Combination Earn-out Liability was $45.5 million. The change in fair value of $46.2 million is recorded in Gain on earnout liability in the Condensed Consolidated Statement of Operations and in Fair value of earn-out liability in the Condensed Consolidated Statement of Cash Flows in the period of change. AIMS Earn-out Liability On August 2, 2023, the Company acquired the remaining 70% of the issued and outstanding ownership and membership interests of AIMS, increasing its interest from 30% to 100%. The AIMS Acquisition was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $16.8 million. The total purchase consideration transferred consists of cash consideration, equity consideration, deferred cash consideration, earn-out consideration, (or AIMS earn-out liability), and the payment of assumed liabilities. As of September 30, 2023, the AIMS earn-out liability of $2.7 million is reported in Other liabilities in the Condensed Consolidated Statement of Financial Position. Since the AIMS earn-out liability meets the definition of a derivative, it is recorded at fair value as a derivative liability on the Condensed Consolidated Statement of Financial Position and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement , with changes in fair value to be recognized in Gain (loss)

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company operates within two business segments: Asset Management and Wealth Management. See Note 1 (Description of the Business). The Company’s business segment information was prepared using the following methodologies and generally represents the information that is relied upon by management in its decision-making process. • Revenues and expenses directly associated with each business segment are included in determining net income/ (loss) by segment. • Indirect expenses (such as general and administrative expenses including executive and indirect overhead costs) not directly associated with specific business segments are allocated to the business segments’ statement of operations. Accordingly, the Company presents segment information consistent with internal management reporting. See Note 1 (Description of the Business) and the table below for more detail on unallocated items. The following tables present the financial information for the Company’s segments for the periods indicated.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The table below presents the Company’s treatment for basic and diluted earnings (loss) per share for instruments outstanding of the Registrant. Potentially dilutive instruments are only considered in the calculation to the extent they would be dilutive. For the Period July 1, 2023 – September 30, January 3, 2023 – September 30, Basic Diluted Basic Diluted Class A Shares Included Included Included Included Class B Shares (1) Excluded If-converted method Excluded If-converted method Warrants (2) None outstanding None outstanding Excluded Treasury stock method Earn-Out Shares Excluded Excluded Excluded Excluded Vested RSUs None outstanding None outstanding None outstanding None outstanding Unvested RSUs Excluded Treasury stock method Excluded Treasury stock method Holbein Earn-In Shares (3) Excluded Treasury stock method Excluded Treasury stock method (1) The if-converted method for these instruments includes adding back to the numerator any related income or loss allocations to noncontrolling interest, as well as any incremental tax expense had the instruments converted into Class A Shares as of the beginning of the period. (2) Prior to the Business Combination, the Company issued warrants to purchase Class A Shares. As of June 30, 2023, all warrants were exchanged for Class A Shares and no warrants are outstanding as of September 30, 2023. (3) During the period July 1, 2023 to September 30, 2023, the Company modified the Holbein Earn-In shares arrangement such that the settlement of the Earn-In shares would be in shares at each service period. At September 30, 2023, the service periods related to the Holbein Earn-In shares had not been completed, and therefore such shares have not been included in the calculation of basic earnings (loss) per share for the periods July 1, 2023 to September 30, 2023 and January 3, 2023 to September 30, 2023. However, in calculating the Company’s diluted earnings (loss) per share, the Company utilized the treasury stock method to determine the potential number of dilutive shares for the periods ended July 1, 2023 to September 30, 2023 and January 3, 2023 to September 30, 2023. For the periods ending March 31, 2023, and June 30, 2023, the Holbein Earn-In shares were excluded from the Company’s diluted earnings per share calculation as the Earn-In shares were classified as contingently issuable common shares. The key terms of the Holbein Earn-Ins are discussed in Note 5 (Equity-Based Compensation). Basic earnings per share is computed by dividing income attributable to controlling interest by the weighted average number of shares of Class A Common Stock outstanding during the period. Diluted earnings per common share excludes potentially dilutive instruments which were outstanding during the period but were anti-dilutive. The following table shows the computation of basic and diluted earnings per share: For the Period (Dollars in Thousands, except share data) July 1, 2023 – September 30, January 3, 2023 – September 30, Net loss attributable to controlling interest - basic $ (88,721) $ (114,019) Net loss available to the Company - diluted $ (88,721) $ (114,019) Weighted-average shares of Class A Common Stock outstanding - basic 63,568,646 60,174,678 Weighted-average shares of Class A Common Stock outstanding - diluted 63,568,646 60,174,678 Loss per Class A Common Stock - basic $ (1.40) $ (1.89) Loss per Class A Common Stock - diluted $ (1.40) $ (1.89) The following potentially dilutive instruments were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive: For the Period July 1, 2023 – September 30, January 3, 2023 – September 30, Class B Common Stock and Class B Units 54,421,975 36,484,979 Warrants — 6,657,084 Earn-outs 10,396,318 10,396,318 Stock Awards 4,594,486 3,067,192

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Tax Receivable Agreement Pursuant to the TRA, the Company will pay certain parties to the Business Combination 85% of certain tax benefits, if any, that it realizes (or in certain cases is deemed to realize) as a result of any increase in tax basis of the assets of Alvarium Tiedemann related to the Business Combination. Amounts payable under the TRA are contingent upon (i) the generation of taxable income over the life of the TRA, (ii) the tax rates in effect as of time periods in which tax benefits are used, and (iii) certain terms governing the rate of interest to be applied to payments under the TRA. As of September 30, 2023, the liability associated with the TRA was approximately $18.0 million and consisted entirely of a liability recorded under ASC 805 associated with the Business Combination, and as such, is presented at fair value through the discount of future anticipated payments. Payments under the TRA that are on account of liabilities arising in connection with the Business Combination will be revalued at the end of each reporting period with the gain or loss recognized in earnings. In connection with the TRA, certain parties to the Business Combination who received Class B Units in Umbrella have the ability to exchange Class B Units in Umbrella For shares of Class A Common Stock in the Company on a 1:1 exchange basis. These future exchanges are anticipated to be treated as taxable exchanges which may provide an increase in the tax basis of the assets of the Company and therefore provide for additional payments under the TRA. TRA liabilities that are generated on account of future exchanges will be recorded under ASC 450, Contingencies . On August 31, 2023, holders of Class B Common Stock exchanged a portion of such Class B Units to the Company, in exchange for shares of Class A Common Stock on a 1:1 basis totaling an amount equal to $7.31 multiplied by the total number of shares of Class B Common Stock exchanged at the time of the transaction. Payments under the TRA will continue until all such tax benefits have been utilized or expired unless (i) the Company exercises its right to terminate the TRA and pays recipients an amount representing the present value of the remaining payments, (ii) there is a change of control or (iii) the Company breaches any of the material obligations of the TRA, in which case all obligations will generally be accelerated and due as if the Company had exercised its right to terminate the TRA. In each case, if payments are accelerated, such payments will be based on certain assumptions, including that the Company will have sufficient taxable income to fully utilize the deductions arising from the increased tax deductions. The estimate of the timing and amount of future payments under the TRA involves several assumptions that do not account for the significant uncertainties associated with those potential payments, including an assumption that the Company will have sufficient taxable income in the relevant tax years to utilize the tax benefits that would give rise to an obligation to make payments. As of September 30, 2023, assuming no material changes in the relevant tax laws and that the Company generates sufficient taxable income to realize the full tax benefit of the increased amortization resulting from the increase in tax basis of certain of AlTi’s assets, we expect to pay approximately $18.0 million under the TRA. Future changes in the fair value of the TRA liability will be recognized in earnings. Any future cash savings and related payments under the TRA due to subsequent exchanges of Class B Units for shares of Class A Common Stock would be accounted for separately from the amount related to the Business Combination. Business Combination Earn-out Under the terms of the Business Combination, upon Closing, the Sponsor and the selling shareholders of TWMH, TIG, and Alvarium became entitled to receive earn-out shares contingent on various share price milestones. Additionally, upon a change of control of the Company, the share price milestones will be deemed to have been met and all the Business Combination Earn-out Securities will be payable to the earn-out holders. The earn-out shares are precluded from being considered indexed to the Company’s own stock and are recognized as a liability at fair value with changes in fair value recognized in earnings. As of September 30, 2023, the fair value of the earn-out shares was $45.5 million. See Note 2 (Summary of Significant Accounting Policies) for additional detail. AIMS Earn-out Liability On August 2, 2023, the Company acquired the remaining 70% of the issued and outstanding ownership and membership interests of AIMS, increasing its interest from 30% to 100%. The AIMS Acquisition was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $16.8 million. The total purchase consideration transferred consists of cash consideration, equity consideration, deferred cash consideration, earn-out consideration, (or AIMS earn-out liability), and the payment of assumed liabilities. As of September 30, 2023, the AIMS earn-out liability of $2.7 million is reported in Other liabilities in the Condensed Consolidated Statement of Financial Position. Since the AIMS earn-out liability meets the definition of a derivative, it is recorded at fair value as a derivative liability on the Condensed Consolidated Statement of Financial Position and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement , with changes in fair value to be recognized in Gain (loss) on earn-out liability in the Condensed Consolidated Statement of Operations and in Fair value of earn-out liability in the Condensed Consolidated Statement of Cash Flows in the period of change. Litigation From time to time, the Company may be involved in legal actions in the ordinary course of business. Although there can be no assurance of the outcome of such legal actions, in the opinion of management, the Company does not have a potential liability related to any current legal proceeding or claim that would individually or in the aggregate materially affects its results of operations, financial condition or cash flows. Home REIT is a real estate investment trust company listed on the London Stock Exchange. Alvarium Fund Managers (UK) Limited (“AFM UK”) is its alternative investment fund manager and AHRA was its investment adviser until June 30, 2023. AFM UK is a wholly owned subsidiary of the Company. AHRA was owned by ARE (another wholly owned subsidiary of the Company) up until December 30, 2022, when AHRA was sold. As such, AHRA was not acquired by the Company pursuant to the Business Combination. Accordingly, AHRA has never been a part of AlTi. For UK regulatory purposes, up until June 30, 2023, AHRA was permitted to perform certain limited regulated activities as an “appointed representative” of its regulated principal firm, ARE (which is authorized and regulated by the UK Financial Conduct Authority). Since November 2022, Home REIT and AHRA have been the subject of a series of allegations in the UK media regarding Home REIT’s operations, triggered by a report issued by a short seller. Following the publication of the short seller report, a UK law firm announced that it was seeking current and former shareholders of Home REIT to potentially bring claims in connection with the allegations. The announcement states that claims will likely be brought against Home REIT itself, its directors, and AFM UK. On October 6, 2023, a pre-action letter of claim was received by, among others, AFM UK and ARE asserting potential claims against those entities relating to the above matters (a pre-action letter of claim is required to be sent by a claimant to a potential defendant under the Practice Direction on Pre-Action Protocols and Conduct contained in the United Kingdom’s Ministry of Justice Civil Procedure Rules prior to a claimant commencing litigation in the UK). The pre-action letter was sent by law firm acting on behalf of a group of current and former shareholders in Home REIT. The pre-action letter does not provide details of the quantum being claimed from any of the potential defendants (whether jointly or severally), and it is not possible at this point in time for us to reliably assess what the quantum of such claims might be, or AFM UK’s and ARE’s potential exposure, though it may potentially be material to the Company. If any litigation or other action is commenced against AFM UK and/or ARE, our current assessment is that any such claims or actions should be defended and would be unlikely to succeed. However, if any claims were commenced, we would anticipate that such claims may involve complex questions of law and fact and we may incur significant legal expenses in defending such litigation. We will continue to assess any potential litigation or regulatory risk associated with the above-mentioned matters. We maintain insurance policies which are intended to provide coverage for various claims against us, subject to the terms and conditions of the relevant policy. Such policies include, among other things, indemnification for legal expenses. We also have access to credit facilities to support the business, if required. These arrangements support our assessment of going concern and of our ability to address any potential financial impact arising from the above.

The notes are an integral part of the Company’s condensed consolidated financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements have been included and are of a normal and recurring nature.The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior period presentations and disclosures, while not required to be recast, may be reclassified to ensure comparability with current period classifications.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make assumptions and estimates that affect the amounts reported in the condensed consolidated financial statements of the Company. The most critical of these estimates are related to (i) the fair value of the investments included in the Billable Assets within AUM/AUA, as this impacts the amount of revenues the Company recognizes each period; (ii) the fair values of the Company’s investments and liabilities with respect to the TRA, Warrants, and Earn-out Securities, as changes in these fair values have a direct impact on the Company’s consolidated net income (loss); (iii) the estimate of future taxable income, which impacts the realizability and carrying amount of the Company’s deferred income tax assets; (iv) the qualitative and quantitative assessments of whether impairments of equity method investments, carried interest vehicles, acquired intangible assets, and goodwill exist; and (v) the determination of whether to consolidate a variable interest entity (“VIE”); and (vi) fair value of assets acquired and liabilities assumed in business combinations, including assumptions with respect to future cash inflows and outflows, discount rates, assets useful lives, market multiples, the allocation of purchase price consideration in the business combination valuation of acquired assets and liabilities, the estimated useful lives of intangible assets, goodwill impairment testing, assumptions used to calculate equity-based compensation, and the realization of deferred tax assets. Inherent in such estimates are judgements relating to future cash flows, which include the Company’s interpretation of current economic indicators and market valuations, and assumptions about the Company’s strategic plans with regard to its operations. While management believes that the estimates utilized in preparing the condensed consolidated financial statements are reasonable and prudent, actual results could differ materially from those estimates.
Consolidation	Consolidation The Company consolidates those entities in which it has a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. The Company determines whether an entity should be consolidated by first evaluating whether it holds a variable interest in the entity. Entities that are not VIEs are further evaluated for consolidation under the voting interest model (“VOE” model). An entity is considered to be a VIE if any of the following conditions exist: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) the holders of equity investment at risk, as a group, lack either the direct or indirect ability through voting rights or similar rights to make decisions that have a significant effect on the success of the entity or the obligation to absorb the expected losses or right to receive the expected residual returns, or (c) the voting rights of some equity investors are disproportionate to their obligation to absorb losses of the entity, their rights to receive returns from an entity, or both and substantially all of the entity’s activities either involve or are conducted on behalf of an investor with disproportionately few voting rights. Fees that are customary and commensurate with the level of services provided by the Company, and where the Company does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, are not considered a variable interest. The Company factors in all economic interests, including proportionate interests through related parties, to determine if fees are considered a variable interest. Where the Company’s interests in funds are primarily management fees and insignificant direct or indirect equity interests through related parties, the Company is not considered to have a variable interest in such entities. The Company consolidates all VIEs for which it is the primary beneficiary. An entity is determined to be the primary beneficiary if it holds a controlling financial interest, which is defined as having (a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company does not consolidate any of the products it manages as it does not hold any direct or indirect interests in such entities that could expose the Company to an obligation to absorb losses of an entity or the right to receive benefits from an entity that could potentially be significant to such entities. The Company determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and continuously reconsiders that conclusion. In evaluating whether the Company is the primary beneficiary, the Company evaluates its direct and indirect economic interests in the entity. The consolidation analysis is generally performed qualitatively, however, if the primary beneficiary is not readily determinable, a quantitative analysis may also be performed. This analysis requires judgment, including: (1) determining whether the equity investment at risk is sufficient to permit the entity to finance its activities without additional subordinated financial support, (2) evaluating whether the equity holders, as a group, can make decisions that have a significant effect on the success of the entity, (3) determining whether two or more parties’ equity interests should be aggregated, (4) determining whether the equity investors have proportionate voting rights to their obligations to absorb losses or rights to receive returns from an entity and (5) evaluating the nature of relationships and activities of the parties involved in determining which party within a related-party group is most closely associated with a VIE and therefore would be deemed the primary beneficiary.
Revenue Recognition	Revenue Recognition Revenue is recognized when the Company transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those goods or services. A five-step framework is utilized that requires an entity to: (i) identify the contract(s) with a customer, which includes assessing the collectability of the consideration to which it will be entitled in exchange for the goods or services transferred to the customer, (ii) identify the performance obligation in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligation in the contract, and (v) recognize revenue when the entity satisfies a performance obligation. Management/Advisory Fees Revenues from contracts with customers consist of investment management, trustee, and custody fees. The Company recognizes revenue at the time of transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue recognized is calculated based on contractual terms, including the transaction price, whether a distinct performance obligation has been satisfied and control is transferred to the customer, and when collection of the revenue is assessed as probable. Investment management, trustee and custody fees are recognized over the period in which the investment management services are performed, using a time-based output method to measure progress. The amount of revenue varies from one reporting period to another as levels of AUA change (from inflows, outflows, and market movements) and the number of days in the reporting period change. For services provided to each client account, the Company charges an investment management fee, inclusive of custody and/or trustee fees, based on the fair value of the AUA of such account representing a single performance obligation. For assets for which valuations are not available on a daily basis, the most recent valuation provided to the Company is used as the fair value for the purpose of calculating the quarterly fee. In certain circumstances, fixed fees are charged to customers on a monthly basis. The nature of the Company’s performance obligation is to provide a series of distinct services in which the customer receives the benefits of the services over time. The Company’s performance obligation is satisfied at the end of each month or quarter, as applicable to the contract with the customer. Fees are charged on a mixture of methodologies that include quarterly in arrears based upon the market value at the end of the quarter, quarterly based on the average daily balance, or monthly. Receivable balances from contracts with customers are included in the fees receivable line in the Condensed Consolidated Statement of Financial Position. There were no write-offs of such fees receivable as of September 30, 2023, and December 31, 2022. Our FOS business is also included in this line item. FOS fees are generally structured to reflect an annual agreed upon fee or they can be structured on a project/time-based fee. FOS fees are typically billed quarterly in arrears. We also generate FOS project/time-based fees arising from accounting, administration fees, set up, the Foreign Account Tax Compliance Act (“FATCA”), and other non-investment advisory services. Incentive Fees The Company is entitled to incentive fees if targeted returns have been achieved in accordance with customer contracts. Incentive fees are calculated using a percentage of net profit from the amount the customers earn. Incentive fees are variable consideration that is generally calculated as applicable to the contract with the customer. We recognize our incentive fees when it is no longer probable that a significant reversal of revenue will occur. Our incentive fees are not subject to clawback provisions. Distributions from Investments The Company has equity interests in three entities pursuant to which it is entitled to distributions based on the terms of the respective arrangements. Distributions from each investment will be recorded upon receipt of the distribution. These distributions are recurring under investment agreements and are structured as either a profit or revenue share of the investment’s management and incentive fees. The Company generates arrangement fees in its co-investment division by arranging private debt or equity financing, generally in connection with an acquisition or an investment. Arrangement fees are typically 50 to 100 basis points of equity value contributed into a transaction. Acquisition fees are typically payable where there are no agency fees or where there is an off-market transaction sourced by the team. Such acquisition fees are usually in the range of 50 to 100 basis points of the purchase price of the relevant acquisition. The equity structures are long-term ( five
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents primarily consist of cash and money market funds. Cash balances maintained by consolidated VIEs are not considered legally restricted and are included in cash and cash equivalents on the Condensed Consolidated Statement of Financial Position. Cash was held across our US and international markets. A majority of cash in the U.S. was held in checking accounts within the credit facility bank group, including at a major global financial institution which management believes is creditworthy.
Restricted Cash and Cash Equivalents	(f) Restricted Cash and Cash Equivalents Restricted cash and cash equivalents consist of balances that are restricted as to withdrawal or usage. As of September 30, 2023 restricted cash and cash equivalents amounted to $3.4 million and are included in the line item Cash and cash equivalents on the Condensed Consolidated Statement of Financial Position. These amounts represent the level of liquidity to be maintained by Company’s certain subsidiaries to meet regulatory requirements. Failing to meet the requirement could lead to censure, fines and ultimately a loss of license.
Compensation and Employee Benefits	Compensation and Employee Benefits Cash-Based Compensation Compensation and benefits consist of salaries, bonuses, commissions, benefits and payroll taxes. Compensation is accrued over the related service period. Equity-Based Compensation Equity-based compensation awards are reviewed to determine whether such awards are equity-classified or liability-classified. Compensation expense related to equity-classified awards is equal to their grant-date fair value and generally recognized on a straight-line basis over the awards’ requisite service period. When certain settlement features require an award to be liability-classified, compensation expense is recognized over the service period, and such amount is adjusted at each statement of financial position date through the settlement date to the then current fair value of such award. The Company recognizes equity-based award forfeitures in the period they occur as a reversal of previously recognized compensation expense. The reduction in compensation expense is determined based on the specific awards forfeited during that period. Furthermore, the Company recognizes all excess tax benefits and deficiencies as income tax benefit or expense in the Condensed Consolidated Statement of Operations.
Foreign Currency Transactions and Foreign Currency	Foreign Currency and Transactions The Company has multiple functional currencies across various consolidated entities. All functional currencies that are not the U.S. dollar are converted upon consolidation at the reporting date. Monetary assets and liabilities denominated in foreign currency are remeasured into U.S. dollars at the closing rates of exchange on the date of the Condensed Consolidated Statement of Financial Position. Non-monetary assets and liabilities denominated in foreign currencies are remeasured into U.S. dollars using the historical exchange rate. The profit or loss arising from foreign currency transactions is remeasured using the rate in effect on the date of the relevant transaction. Gains and losses on transactions denominated in foreign currencies due to changes in exchange rates are recorded within Foreign currency translation adjustments. Gains and losses on certain financing transactions which the Company intends to repay in the foreseeable future are recorded in net income.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC 740. Under this method, deferred tax assets and liabilities are determined based on differences between the condensed consolidated financial statement carrying amounts and tax bases of assets and liabilities and operating loss and tax credit carryforwards and are measured using the enacted tax rates that are expected to be in effect when the differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the Condensed Consolidated Statement of Operations in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to an amount that, in the opinion of management, is more likely than not to be realized, meaning the likelihood of realization is greater than 50%. The Company accounts for uncertain tax positions by reporting a liability for unrecognizable tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.
Other Assets	Other assetsOther assets include prepaid expenses, miscellaneous receivables, current income taxes receivable, fixed assets, and software licenses. The Company amortizes assets over their respective useful lives, as applicable.
Investments	Investments Investments in Debt Securities. The Company classifies debt investments as held-to-maturity or trading based on the Company’s intent and ability to hold the debt security to maturity or its intent to sell the security. The Company does not have any held-to-maturity debt investments. Trading securities are those investments that are purchased principally for the purpose of selling them in the near term. Trading securities are carried at fair value on the Condensed Consolidated Statement of Financial Position with changes in fair value recorded in nonoperating income (expense) on the Condensed Consolidated Statement of Operations. Investments in Equity Securities . Equity securities are generally carried at fair value on the Condensed Consolidated Statement of Financial Position in accordance with ASC 321, “Investments – Equity Securities.” Changes in fair value are recorded in net gains (losses) in the Condensed Consolidated Statement of Operations. Equity Method . The Company applies the equity method of accounting for equity investments where the Company does not consolidate the investee but can exert significant influence over the financial and operating policies of the investee. The evaluation of whether the Company exerts control or significant influence over the financial and operational policies of its investees is based on the facts and circumstances surrounding each individual investment. The Company’s share of the investee’s underlying net income or loss is recorded as net gain (loss) on investments within current period earnings. The Company’s share of net income of the investee is recorded based upon the most current information available at the time, which may precede the date of the Condensed Consolidated Statement of Financial Position. Due to the nature and size of its investees, the Company has adopted a lag in reporting for certain equity method investees for which the Company cannot reliably obtain financial information on a regular basis. Distributions received reduce the Company’s carrying value of the investee and the cost basis if deemed to be a return of capital. For certain investments, the Company may apply the alternative fair value option to the investment at initial measurement. The fair value measurement of investments in which the option is elected will be measured in accordance with ASC 825. For equity method investments and nonmarketable investments, impairment evaluation considers qualitative factors, including the financial conditions and specific events related to an investee, which may indicate the fair value of the investment is less than the carrying value. For held-to-maturity investments, impairment is evaluated using market values, when available, or the expected cash flows of the investment.
Leases	LeasesThe Company accounts for its leases in accordance with ASC 842, Leases and recognizes a lease liability and right-of-use asset in the Condensed Consolidated Statement of Financial Position for contracts that it determines are leases or contain a lease. The Company evaluates leases at their inception to determine if they are to be accounted for as an operating lease or a finance lease. A lease is accounted for as a finance lease if it meets one of the following five criteria: (i) the lease has a purchase option that is reasonably certain of being exercised, (ii) the present value of the future cash flows is substantially all of the fair market value of the underlying asset, (iii) the lease term is for a significant portion of the remaining economic life of the underlying asset, (iv) the title to the underlying asset transfers at the end of the lease term, or (v) if the underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the term. Leases that do not meet the finance lease criteria are accounted for as an operating lease. At the inception of a finance lease, an asset and finance lease obligation are recorded at an amount equal to the lesser of the present value of the minimum lease payments and the property’s fair market value. Finance lease obligations are classified as either current or long-term based on the due dates of future lease payments, net of interest. The Company’s lease portfolio primarily consists of operating leases for office space in various countries around the world. The Company also has operating leases for office equipment and vehicles, which are not significant. The Company does not separate non-lease components from lease components for its office space and equipment operating leases and instead accounts for each separate lease component and its associated non-lease component as a single lease component. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the leases. The Company’s right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of lease payments over the lease term. Lease right-of-use assets include initial direct costs incurred by the Company and are presented net of deferred rent and lease incentives. Absent an implicit interest rate in the lease, the Company uses its incremental borrowing rate, adjusted for the effects of collateralization, based on the information available at commencement in determining the present value of lease payments. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease right-of-use assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company does not recognize a lease liability or right-of-use asset on the balance for short-term leases. Instead, the Company recognizes short-term lease payments as an expense on a straight-line basis over the lease term. A short-term lease is defined as a lease that, at the commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. When determining whether a lease qualifies as a short-term lease, the Company evaluates the lease term and the purchase option in the same manner as all other leases.
Intangible assets other than goodwill, net	Intangible assets other than goodwill, net The Company recognized certain finite-lived intangible assets as a result of the Business Combination. The Company’s finite-lived intangible assets consist of Trade Names, Customer Relationships, Investment Management Agreements, and Backlog. Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives. The Company tests finite-lived intangible assets for impairment if certain events occur or circumstances change indicating that the carrying amount of the intangible asset may not be recoverable. The Company evaluates impairment by comparing the estimated fair value attributable to the intangible asset with its carrying amount. If an impairment exists, the Company adjusts the carrying value to equal the fair value by taking a charge through earnings. The Company also recognized certain indefinite-lived intangible assets as a result of the Business Combination consisting of certain investment management agreements. These indefinite-lived intangibles are not subject to amortization, but are evaluated for impairment at least annually. In assessing its indefinite-lived intangible assets for impairment, the Company has the option to first perform a qualitative assessment to determine whether events or circumstances exist that lead to a determination that it is unlikely that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If the Company determines that it is unlikely that the fair value of an indefinite-lived intangible asset is less than its carrying amount, the Company is not required to perform any additional tests in assessing the
Goodwill	Goodwill Goodwill represents the excess of the purchase price in a business combination over the fair value of the tangible and intangible assets acquired and the liabilities assumed. Under ASC 350, Intangibles—Goodwill and Other , goodwill is not amortized, but rather is subject to an annual impairment test. Goodwill represents the excess of consideration over identifiable net assets of an acquired business. Goodwill is allocated at a reporting unit level. The Company has two reporting units, Asset Management and Wealth Management, and tests goodwill annually for impairment at each reporting unit. If, after assessing qualitative factors, the Company believes that it is more-likely-than-not that the fair value of the reporting unit inclusive of goodwill is less than its carrying amount, the Company will perform a quantitative assessment to determine whether an impairment exists. If an impairment exists, the Company adjusts the carrying value of goodwill so that the carrying value of the reporting unit is equal to its fair value by taking a charge through earnings. The Company also tests goodwill for impairment in other periods if an event occurs or circumstances change such that it is more-likely-than-not to reduce the fair value of the reporting unit below its carrying amount. As of September 30, 2023, the Company recognized goodwill impairment charges of $153.6 million for the Asset Management segment in Impairment loss on goodwill and intangible assets in the Condensed Consolidated Statement of Operations. The Company concluded that the estimated fair value of the Wealth Management reporting unit was greater than its carrying value, and as such, no impairment charge was required. See Note 13 (Goodwill, net).
Fixed Assets, Net	Fixed Assets, NetFixed assets are recorded at cost, less accumulated depreciation and amortization, and are included in the “Other assets” line item in the Company’s Condensed Consolidated Statement of Financial Position. Fixed assets are depreciated or amortized on a straight-line basis, with the corresponding depreciation and amortization expense included within general, administrative and other expenses in the Company’s Condensed Consolidated Statement of Operations. The estimated useful life for leasehold improvements is the lesser of the remaining lease term and the life of the asset, while other fixed assets are generally depreciated over a period of two
Debt Obligations, Net	Debt Obligations, NetThe Company’s debt obligations are recorded at amortized cost, net of any debt issuance costs, discounts and premiums. Debt issuances costs are deferred and along with discounts and premiums are amortized to interest expense in the Condensed Consolidated Statement of Operations over the life of the related debt instrument using the effective interest method. Unamortized debt issuance costs, discounts and premiums are written off to net losses on retirement of debt in the Condensed Consolidated Statement of Operations when the Company prepays borrowings prior to maturity.
Tax Receivable Agreement	Tax Receivable AgreementThe TRA liability represents amounts payable to certain pre-Business Combination equity holders of the Company. The portion of the TRA liability related to the Business Combination is deemed contingent consideration payable to the previous owners and is carried at fair value, with changes in fair value reported within other gain (loss) in the Condensed Consolidated Statement of Operations. Future exchanges of Class B Units for shares of Class A Common Stock may increase the TRA liability. Those increases will be carried at a value equal to the expected future payments due under the TRA. On August 31, 2023, holders of shares of Class B Common Stock exchanged a portion of such Class B Units to the Company, in exchange for shares of Class A Common Stock on a 1:1 basis totaling an amount equal to $7.31 multiplied by the total number of shares of Class B Common Stock exchanged at the time of the transaction. For future increases due to exchanges the Company will record an initial estimate of future payments under the TRA portion as a decrease to additional paid-in capital in the Condensed Consolidated Statement of Financial Position. Subsequent adjustments to the liability for future payments under the TRA related to changes in estimated future tax rates or state income tax apportionment are recognized through current period earnings in the Condensed Consolidated Statement of Operations.
Warrant Liability, Business Combination Earn-out Liability, AIMS Earn-out Liability, and Derivative Financial Instruments	Warrant LiabilityThe Company evaluated the Warrants in accordance with ASC 815-40 and concluded that a provision in the warrant agreement related to certain tender or exchange offers precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative, the Warrants are recorded as derivative liabilities on the balance sheet and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in Other Income/(Expenses) in the Condensed Consolidated Statement of Operations in the period of change. Prior to the Business Combination the Sponsor held private warrants that were contributed to the Company and legally cancelled. The contribution and cancellation of these warrants resulted in derecognition of the private warrants and accounted for in additional paid in capital as of January 3, 2023. The Company subsequently issued new warrants with terms identical to those of the public warrants to the Target Companies’ selling shareholders classified as derivative liabilities. On June 7, 2023, the Company closed an offer and consent solicitation and entered into a warrant amendment, pursuant to which the remaining Warrants were exchanged. In total, the Warrants were exchanged for approximately 4,962,221 shares of Class A Common Stock. See Note 1 (Description of the Business). Following the exchange, none of the Warrants remain outstanding as of September 30, 2023. Business Combination Earn-out LiabilityThe Business Combination Earn-out Securities, comprised of 3.3 million Class A Shares, 7.1 million shares of Class B Common Stock, and 7.1 million Class B Units (one Class B share and one Class B Unit comprising a Paired Interest, as described in Note 3 (Business Combination)), are payable to the Sponsor and the selling shareholders of TWMH, TIG, and Alvarium upon the achievement of certain vesting conditions in accordance with the terms of the Business Combination Agreement. Upon the Company’s Class A Share price meeting a volume-weighted average price threshold of $12.50 for 20 out of 30 trading days within five years of the Closing, fifty percent of the Business Combination Earn-out Securities will vest and be issued in settlement of the Business Combination Earn-out Liability (or, in the case of the Sponsor, which shares have already been issued, will no longer be subject to forfeiture). Upon the Company’s Class A Share price meeting a volume-weighted average price threshold of $15.00 for 20 out of 30 trading days within five years of the Closing, the remaining fifty percent of the Business Combination Earn-out Securities will vest and be issued. If, within five years of the Closing, a change of control event occurs (as defined in the Business Combination Agreement), any Business Combination Earn-out Securities not previously issued will be deemed to have vested and will be issued (or, in the case of the Sponsor, which shares have already been issued, will no longer be subject to forfeiture). The Company evaluated the terms of the Business Combination earn-out agreement in accordance with ASC 815-40 and concluded that the Business Combination Earn-out Securities are precluded from being accounted for as a component of equity. Since the Business Combination earn-out agreement meets the definition of a derivative, the Business Combination Earn-out Securities are recorded in Earn-out liability, at fair value as a derivative liability on the Condensed Consolidated Statement of Financial Position and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in Gain (loss) on earn-out liability in the Condensed Consolidated Statement of Operations and in Fair value of earn-out liability in the Condensed Consolidated Statement of Cash Flows in the period of change.AIMS Earn-out Liability On August 2, 2023, (the “AIMS Acquisition Date”), the Company acquired the remaining 70% of the issued and outstanding ownership and membership interests of Alvarium Investment Managers (Suisse) SA (“AIMS”), increasing its interest from 30% to 100% (the “AIMS Acquisition”). The AIMS Acquisition was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $16.8 million. The total purchase consideration transferred consists of cash consideration, equity consideration, deferred cash consideration, earn-out consideration (“AIMS earn-out liability”), and the payment of assumed liabilities. As of September 30, 2023, the AIMS earn-out liability of $2.7 million is reported in Other liabilities in the Condensed Consolidated Statement of Financial Position. Since the AIMS earn-out liability meets the definition of a derivative, it is recorded at fair value as a derivative liability on the Condensed Consolidated Statement of Financial Position and measured at fair value at each reporting date in accordance with ASC 820, Fair Value Measurement , with changes in fair value to be recognized in Gain (loss) on earn-out liability in the Condensed Consolidated Statement of Operations and in Fair value of earn-out liability in the Condensed Consolidated Statement of Cash Flows in the period of change. See Note 3 (Business Combinations and Divestiture) for further information.
Non-controlling Interests	Non-controlling InterestsNon-controlling interests in the net assets of consolidated subsidiaries are identified separately from the Company’s equity. Non-controlling interests consist of the amount of those interests at the date of the original Business Combination and the minority’s share of changes in equity since the date of the Business Combination. The proportions of profit and loss and changes in equity allocated to the owners of the parent and to the non-controlling interests are determined on the basis of existing ownership interests.
Segment Reporting	Segment Reporting Our business is organized into two operating segments: Wealth Management and Asset Management. Described below are the segments and the revenue generated by each, which broadly fall into three categories: recurring management, advisory, or administration fees; performance or incentive fees; and transaction fees. Wealth Management Our Wealth Management services principally consist of investment management and advisory services, trusts and administrative services, and family office services. Our Wealth Management client base includes HNWIs, families, single family offices, foundations, and endowments globally. Investment management or advisory fees are the primary source of revenue in our Wealth Management segment. These fees are generally calculated based on a percentage of the value of each client’s AUM or AUA (as applicable). As of September 30, 2023, this segment had $48.5 billion in AUM/AUA. Investment Management and Advisory Services In our investment management and advisory services teams, we diversify our clients’ portfolios across risk factors, geographies, and asset classes including private equity, private debt, hedge funds, real estate, and other assets through highly experienced third-party managers, who may be hard to access. Trusts and Administration Services The trusts and administration services that we provide include entity formation and management, creating or modifying trust instruments and/or administrative practices to meet beneficiary needs, full corporate, trustee-executor, and fiduciary services. We also offer provision of directors and company secretarial services, administering entity ownership of intellectual property rights, advice and administration services in connection with investments in marine and aviation assets, and administering entity ownership of fine art and collectibles. Family Office Services Our family office services are tailored outsourced family office solutions and administrative services which we provide primarily to our larger clients.

Asset Management Our Asset Management services include alternatives platform and public and private real estate (including co-investment) businesses. Alternatives Platform Our alternatives platform represents our legacy TIG business which is an alternative asset manager. This platform includes our TIG Arbitrage strategy and funds managed by our External Strategic Managers. Our alternatives platform client base is predominantly comprised of institutional investors. The TIG Arbitrage strategy is our event-driven strategy through which management fees and incentive fees based on performance are received from the underlying funds and accounts. The strategies of our External Strategic Managers include Real Estate Bridge Lending, European Equities and Asian Credit and Special Situations. We receive distributions from our External Strategic Managers through our profit or revenue sharing arrangements that are generated through their management and incentive fees based on performance of the underlying investments. As of September 30, 2023, this platform had $7.7 billion in AUM/AUA. Real Estate - Public and Private Our real estate business includes fund management services as well as co-investment solutions. As of September 30, 2023, this business had approximately $12.0 billion of AUM/AUA. Fund Management Our real estate fund management business manages two funds based in the United Kingdom, LXi, a publicly traded REIT, and HLIF, a private fund. The funds are marketed primarily in the United Kingdom to institutional investors, primarily pension funds, as well as to retail investors. Fees from our real estate fund management business are earned from management and advisory fees. Co-Investment Our real estate co-investment business, oversees deal origination, documentation, and structuring from inception to exit for a variety of strategies including development, income, value-add, and planning. Investors are typically HNWIs, single family offices, and institutional investors. Fees earned related to our real estate co-investment business include private market, incentive fees, management and advisory fees, and placement and brokerage fees. As of September 30, 2023, our real estate co-investment platform has deployed more than $7.5 billion of capital (inclusive of capital raised for our public and private real estate funds), of which approximately 14% has been invested by legacy Alvarium shareholders and senior employees.
Other Income / Expenses	Other Income / Expenses Other income and expenses is comprised of unrealized gains (losses) on investments, interest and dividend income (expense), income from equity method investees, and other items. The Company holds investments in common stock, mutual funds, exchange-traded funds, and exchange-traded notes, which represent investments in equity and debt securities. The Company earns realized and unrealized gains and losses which depend on investment performance. Interest income is earned through its investments in exchange-traded notes. These generally include debt securities held on a short- or medium-term basis when the Company has excess cash. The Company recognizes and records interest income using the effective interest method.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which modifies ASC 805 to require an acquiring entity in a business combination to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with ASC 606 as if it had originated the contracts. Under current GAAP, an acquirer generally recognizes such items at fair value on the acquisition date. This guidance is effective for annual and interim periods beginning after December 15, 2022, with early adoption permitted. The Company adopted this guidance on January 1, 2022 and applied the guidance prospectively to business combinations that occurred after this date. The adoption of this guidance did not have a material effect on the Company’s condensed consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments in this update clarify the guidance in ASC 820 when measuring the fair value of an equity security subject to contractual sale restrictions and introduce new disclosure requirements related to such equity securities. The amendments are effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The Company does not expect the impact of this guidance to be material to its condensed consolidated financial statements. The Company has considered all newly issued accounting guidance that is applicable to its operations and the preparation of its unaudited condensed consolidated statements, including those it has not yet adopted. The Company does not believe that any such guidance has or will have a material effect on its financial position or results of operations.

Earnings Per Share [Abstract]
Schedule of Earnings Per Share, Basic and Diluted	The table below presents the Company’s treatment for basic and diluted earnings (loss) per share for instruments outstanding of the Registrant. Potentially dilutive instruments are only considered in the calculation to the extent they would be dilutive. For the Period July 1, 2023 – September 30, January 3, 2023 – September 30, Basic Diluted Basic Diluted Class A Shares Included Included Included Included Class B Shares (1) Excluded If-converted method Excluded If-converted method Warrants (2) None outstanding None outstanding Excluded Treasury stock method Earn-Out Shares Excluded Excluded Excluded Excluded Vested RSUs None outstanding None outstanding None outstanding None outstanding Unvested RSUs Excluded Treasury stock method Excluded Treasury stock method Holbein Earn-In Shares (3) Excluded Treasury stock method Excluded Treasury stock method (1) The if-converted method for these instruments includes adding back to the numerator any related income or loss allocations to noncontrolling interest, as well as any incremental tax expense had the instruments converted into Class A Shares as of the beginning of the period. (2) Prior to the Business Combination, the Company issued warrants to purchase Class A Shares. As of June 30, 2023, all warrants were exchanged for Class A Shares and no warrants are outstanding as of September 30, 2023. (3) During the period July 1, 2023 to September 30, 2023, the Company modified the Holbein Earn-In shares arrangement such that the settlement of the Earn-In shares would be in shares at each service period. At September 30, 2023, the service periods related to the Holbein Earn-In shares had not been completed, and therefore such shares have not been included in the calculation of basic earnings (loss) per share for the periods July 1, 2023 to September 30, 2023 and January 3, 2023 to September 30, 2023. However, in calculating the Company’s diluted earnings (loss) per share, the Company utilized the treasury stock method to determine the potential number of dilutive shares for the periods ended July 1, 2023 to September 30, 2023 and January 3, 2023 to September 30, 2023. For the periods ending March 31, 2023, and June 30, 2023, the Holbein Earn-In shares were excluded from the Company’s diluted earnings per share calculation as the Earn-In shares were classified as contingently issuable common shares. The key terms of the Holbein Earn-Ins are discussed in Note 5 (Equity-Based Compensation). Basic earnings per share is computed by dividing income attributable to controlling interest by the weighted average number of shares of Class A Common Stock outstanding during the period. Diluted earnings per common share excludes potentially dilutive instruments which were outstanding during the period but were anti-dilutive. The following table shows the computation of basic and diluted earnings per share: For the Period (Dollars in Thousands, except share data) July 1, 2023 – September 30, January 3, 2023 – September 30, Net loss attributable to controlling interest - basic $ (88,721) $ (114,019) Net loss available to the Company - diluted $ (88,721) $ (114,019) Weighted-average shares of Class A Common Stock outstanding - basic 63,568,646 60,174,678 Weighted-average shares of Class A Common Stock outstanding - diluted 63,568,646 60,174,678 Loss per Class A Common Stock - basic $ (1.40) $ (1.89) Loss per Class A Common Stock - diluted $ (1.40) $ (1.89)
Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share	The following potentially dilutive instruments were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive: For the Period July 1, 2023 – September 30, January 3, 2023 – September 30, Class B Common Stock and Class B Units 54,421,975 36,484,979 Warrants — 6,657,084 Earn-outs 10,396,318 10,396,318 Stock Awards 4,594,486 3,067,192
