Organization and Nature of Business Abstract
Organization and Nature of Business	Organization and Nature of Business Perella Weinberg Partners and its consolidated subsidiaries, including PWP Holdings LP (“PWP OpCo”) (collectively, “PWP” and the “Company”), is a global independent advisory firm that provides strategic and financial advice to a wide range of clients. The Company’s activities as an investment banking advisory firm constitute a single business segment that provides a range of advisory services related to mission-critical strategic and financial decisions, mergers and acquisitions advice and execution, capital markets advisory, shareholder and defense advisory, capital structure and restructuring, underwriting, equity research and private capital raising. Perella Weinberg Partners (formerly known as FinTech Acquisition Corp. IV (“FTIV”)) was incorporated in Delaware on November 20, 2018 as a special purpose acquisition company for the purpose of acquiring through a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business transaction, one or more businesses or assets. On June 24, 2021 (the “Closing Date” or “Closing”), the Company consummated its previously announced business combination pursuant to that certain Business Combination Agreement, dated as of December 29, 2020, by and among FTIV, FinTech Investor Holdings IV, LLC, FinTech Masala Advisors, LLC (together with FinTech Investor Holdings IV, LLC, the “Sponsor”), PWP OpCo, PWP GP LLC, PWP Professional Partners LP (“Professional Partners”), and Perella Weinberg Partners LLC (“Professionals GP”) (the “Business Combination Agreement”). As contemplated by the Business Combination Agreement, (i) FTIV acquired certain partnership interests in PWP OpCo, (ii) PWP OpCo became jointly-owned by Perella Weinberg Partners, Professional Partners and certain existing partners of PWP OpCo, and (iii) PWP OpCo serves as the Company’s operating partnership as part of an umbrella limited partnership C-corporation (Up-C) structure (collectively with the other transactions contemplated by the Business Combination Agreement, the “Business Combination”). See Note 3 – Business Combination for additional discussion related to the transaction. The operations of PWP OpCo are conducted through a wholly-owned subsidiary, Perella Weinberg Partners Group LP (“PWP Group”), and its subsidiaries which are consolidated in these financial statements. PWP GP LLC is the general partner that controls PWP OpCo. The limited partner interests of PWP OpCo are held by Investor Limited Partners (the “ILPs”) and Professional Partners. The Company shareholders are entitled to receive a portion of PWP OpCo’s economics through their direct ownership interests in shares of Class A common stock of PWP. The non-controlling interest owners of PWP OpCo receive economics through ownership of PWP OpCo Class A partnership units (“PWP OpCo Units”). See Note 11 – Stockholders’ Equity for additional information. Historical Transactions PWP OpCo was formed under Delaware law on November 30, 2016 in conjunction with a business combination between NoCo A L.P. and Tudor, Pickering, Holt & Co., LLC. Prior to February 28, 2019, PWP OpCo owned and operated two distinct businesses: investment banking advisory (“Advisory business”) and asset management (“Asset Management business”). On February 28, 2019 (the “Separation Date”), a reorganization of the existing Advisory and Asset Management businesses of PWP Holdings LP was effected which resulted in the spin-off of its Asset Management business (the “Separation”). PWP Holdings LP was divided into (i) PWP OpCo, which holds the former Advisory business and (ii) PWP Capital Holdings LP, which holds the former Asset Management business. In connection with the Separation, the net assets primarily related to the Asset Management business were allocated to PWP Capital Holdings LP and the net assets primarily related to the Advisory business were allocated to PWP OpCo. Subsequent to the Separation, the ILPs and Professional Partners hold equity in both PWP OpCo and PWP Capital Holdings LP.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements reflect the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Business Combination was treated as a reverse recapitalization transaction between entities under common control, whereby PWP OpCo was considered the accounting acquirer and predecessor entity and therefore recognized the carrying value of the net assets of FTIV as an equity contribution with no incremental goodwill or intangible assets. The historical operations of PWP OpCo are deemed to be those of the Company. Thus, the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect (i) the historical operating results of PWP OpCo prior to the Business Combination and (ii) the combined results of the Company following the Business Combination. See Note 3 – Business Combination for additional discussion related to the transaction. These condensed consolidated financial statements and notes thereto are unaudited, and as permitted by the interim reporting rules and regulations set forth by the Securities and Exchange Commission (the “SEC”), exclude certain financial information and note disclosures normally included in annual audited financial statements prepared in accordance with U.S. GAAP. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s definitive proxy statement, dated May 27, 2021 (as amended or supplemented, including the filing of definitive additional materials, the “Proxy Statement”). The condensed consolidated financial statements reflect all material adjustments of a normal recurring nature that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods. All intercompany balances and transactions between the consolidated subsidiaries comprising the Company have been eliminated in the accompanying condensed consolidated financial statements. Use of Estimates The preparation of the condensed consolidated financial statements and related disclosures in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and the assumptions underlying these estimates are reviewed periodically, and the effects of revisions are reflected in the period in which they are determined to be necessary. In preparing the condensed consolidated financial statements, management makes estimates regarding the following:  adequacy of the allowance for credit losses;  measurement and realization of deferred taxes;  measurement of equity-based awards;  evaluation of goodwill and intangible assets;  fair value measurement of financial instruments; and  other matters that affect the reported amounts and disclosures of contingencies in the condensed consolidated financial statements. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents includes cash and highly liquid investments with original maturities of three months or less from the date of purchase. As of September 30, 2021 and December 31, 2020 , the Company had no cash equivalents. The Company maintains cash with banks and brokerage firms, which from time to time may exceed federally insured limits. Restricted cash represents cash that is not readily available for general purpose cash needs. As of both September 30, 2021 and December 31, 2020, the Company had restricted cash of $ 1.8 million maintained as collateral for letters of credit related to the Company’s New York City and Paris office leases. A reconciliation of the Company’s cash, cash equivalents and restricted cash as of September 30, 2021 and September 30, 2020 is presented below: September 30, 2021 2020 Cash $ 415,839 $ 186,225 Cash equivalents - - Restricted cash 1,835 1,835 Cash, cash equivalents and restricted cash as shown on statements of cash flows $ 417,674 $ 188,060 Accounts Receivable Accounts receivable are presented net of allowance for credit losses based on the Company’s assessment of collectability. The Company regularly reviews its accounts receivable for collectability and an allowance is recognized for credit losses, if required. As of September 30, 2021 and December 31, 2020, $ 47.9 million and $ 5.1 million , respectively, of accrued revenue was included in Accounts receivable, net of allowance on the Condensed Consolidated Statements of Financial Condition. Accrued revenue represents amounts due from clients and recognized as revenue in accordance with the Company’s revenue recognition policies but unbilled as of September 30, 2021 and December 31, 2020. Accounts receivable represents amounts due from clients from various industry and geographic backgrounds. As of September 30, 2021, certain accounts receivable in the aggregate amount of $ 26.5 million were individually greater than 10% of the Company’s total accounts receivable and were concentrated with one client. Of that amount, all was subsequently received after September 30, 2021. As of December 31, 2020 , there were no accounts receivable individually greater than 10% of the Company’s total accounts receivable. Allowance for Credit Losses On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), under the modified retrospective approach. This new standard replaces the incurred loss impairment methodology for financial instruments with the current expected credit loss (“CECL”) model which requires an estimate of future credit losses. The Company maintains an allowance for credit losses that, in management’s opinion, provides for an adequate reserve to cover estimated losses on accounts receivable. The Company determines the adequacy of the allowance by estimating the probability of loss based on the Company’s historical credit loss experience of its client receivables and taking into consideration current market conditions and supportable forecasts that affect the collectability of the reported amount. The Company updates its average credit loss rates periodically and maintains a quarterly allowance review process to consider current factors that would require an adjustment to the credit loss allowance. In addition, the Company periodically performs a qualitative assessment to monitor risks associated with current and forecasted conditions that may require an adjustment to the expected credit loss rates. The Company also regularly reviews the age of the receivables, credit worthiness of the client and the current economic conditions that may affect a client’s ability to pay such amounts owed to the Company and as a result, may recognize a specific credit loss reserve. Changes to expected credit losses during the period are included in General, administrative and other expenses in the Condensed Consolidated Statements of Operations. After concluding that a reserved accounts receivable is no longer collectible, the Company reduces both the gross receivable and the allowance for credit losses . Consolidation The Company’s policy is to consolidate entities in which the Company has a controlling financial interest and variable interest entities where the Company is deemed to be the primary beneficiary. The Company is deemed to be the primary beneficiary of a variable interest entity (“VIE”) when it has both (i) the power to make the decisions that most significantly affect the economic performance of the VIE and (ii) the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. PWP is the primary beneficiary of and consolidates PWP OpCo, a VIE. The assets and liabilities of PWP OpCo represent substantially all of the Company's consolidated assets and liabilities with the exception of certain cash, income taxes payable, and deferred tax balances as well as all amounts due pursuant to the tax receivable agreement. As of September 30, 2021 and December 31, 2020, the net assets of PWP OpCo were $ 259.9 million and $ 74.2 million , respectively. As of September 30, 2021 and December 31, 2020 , the Company did not consolidate any VIEs other than PWP OpCo that were deemed material to the condensed consolidated financial statements. Equity Method Investments When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity’s operating and financial decisions, the Company applies the equity method of accounting. The investment balance related to an equity method investee reflects the Company’s share of contributions made to, distributions received from, and the equity earnings and losses of the investee. Equity method investments are included within Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. The Company reflects its share of income and losses of the investee in Other income (expense) on the Condensed Consolidated Statements of Operations using the most recently available earnings data for the reporting period. Prepaid Expenses and Other Assets The majority of Prepaid expenses and other assets consists of prepaid expenses, and from time to time, deferred offering costs and receivables from carrying brokers for unsettled trades as noted below. Prepaid expenses relate to various services, including subscriptions, software licenses and insurance, which are amortized over the life, related service period or policy. Deferred offering costs are associated with the reorganization and recapitalization efforts related to the pursuit of becoming a publicly traded company. The Company initially pursued a traditional initial public offering but later terminated this process in May 2020. Upon termination, the Company expensed all previously deferred offering costs totaling $ 14.8 million to Professional fees on the Condensed Consolidated Statements of Operations. Later in 2020, the Company reinitiated efforts of becoming a publicly traded company via the Business Combination and deferred certain offering costs until the Closing Date. These costs were netted against proceeds of the Business Combination on the Closing Date, and as such, no deferred offering costs are included within Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition as of September 30, 2021. As of December 31, 2020, cumulative offering costs of $ 9.1 million were deferred within Prepaid expenses and other assets. Tudor, Pickering, Holt & Co. Securities Canada, ULC (“TPH Canada”) executes certain client trades through a counterparty other than its carrying broker (referred to as “broker-to-broker trades”). Per the introducing broker agreement between TPH Canada and its carrying broker, TPH Canada assumes the risk of any failed obligations with respect to broker-to-broker trades and is required to reimburse the carrying broker for any loss which the carrying broker may sustain as a result of these trades. TPH Canada is deemed to be a principal with regards to broker-to-broker trades; and therefore, the value of unsettled broker-to-broker trades as of September 30, 2021 and December 31, 2020 in the amount of $ 12.8 million and $ 0.1 million , respectively, was recorded as a receivable from the carrying broker or other counterparty as well as a corresponding payable to the carrying broker or other counterparty, which were included in Prepaid expenses and other assets and Accounts payable, accrued expenses and other liabilities, respectively, on the Condensed Consolidated Statements of Financial Condition. Subsequent to September 30, 2021 , these trades were settled and the related receivable and payable were derecognized. Warrants The Company evaluated the public and private warrants under Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, and concluded that they do not meet the criteria to be classified as equity in the Condensed Consolidated Statements of Financial Condition. Since the public and private warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities at fair value upon the closing of the Business Combination in accordance with ASC 820, Fair Value Measurement , with subsequent changes in their respective fair values recorded in Change in fair value of warrant liabilities on the Condensed Consolidated Statements of Operations and on the Condensed Consolidated Statements of Cash Flows. Tax Receivable Agreement In connection with the Business Combination as described in Note 3 – Business Combination, PWP entered into a tax receivable agreement with PWP OpCo, Professional Partners and ILPs under which PWP agreed to payment of 85 % of the amount of savings, if any, that PWP realizes in U.S. federal, state, local and foreign income taxes as a result of (i) exchanges of interests in PWP OpCo for cash or stock of the Company and certain other transactions and (ii) payments made under the tax receivable agreement. Management’s best estimate of the amounts expected to be owed in connection with the tax receivable agreement at each reporting date are reported within the Amount due pursuant to tax receivable agreement on the Condensed Consolidated Statements of Financial Condition. Income Taxes Prior to the Business Combination, the Company operated as a partnership, and therefore, was generally not subject to U.S. federal and state corporate income taxes. Subsequent to the Business Combination, PWP is a corporation and is subject to U.S. federal and state corporate income taxes on its proportionate share of taxable income generated by the operating partnership, PWP OpCo, as well as any standalone income (or loss) generated at the PWP entity level. PWP OpCo is treated as a partnership, and as a result, taxable income (or loss) generated by PWP OpCo flows through to its limited partners, including PWP, and is generally not subject to U.S. federal or state income tax at the partnership level. The Company primarily conducts business through disregarded entities held by PWP OpCo, as well as non-U.S. subsidiaries which generally operate as corporate entities in various non-U.S. jurisdictions. Certain non-U.S. subsidiaries are subject to income taxes in their respective local jurisdictions, and therefore, the related income tax provision is reported in the Condensed Consolidated Statements of Operations. Taxes are accounted for using the asset and liability method of accounting pursuant to ASC 740, Income Taxes (“ASC 740”). Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases, using tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent on the amount, timing and character of the Company’s future taxable income. When evaluating the realizability of deferred tax assets, all evidence – both positive and negative – is considered. This evidence includes, but is not limited to, expectations regarding future earnings, future reversals of existing temporary tax differences and tax planning strategies. The Company analyzes its tax positions for all U.S. federal, state and local tax jurisdictions where it is required to file income tax returns in accordance with the provisions of ASC 740. This standard establishes consistent thresholds for recognizing the benefits of tax return positions in the financial statements as more-likely-than-not to be sustained by the relevant taxing authority upon audit. This standard requires a two-step process in which (i) determination is made whether it is more-likely-than-not that the tax position will be sustained based on the technical merits of the position, and (ii) those tax positions that meet the more-likely-than-not threshold are recognized as the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. If upon performance of an assessment pursuant to ASC 740 the Company determines that uncertainties in tax positions exist that do not meet the minimum threshold for recognition of the related tax benefit, a liability is recorded in the condensed consolidated financial statements. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits as Interest expense and General, administrative and other expenses in the Condensed Consolidated Statements of Operations. Equity-Based Compensation Equity-based compensation relates to equity-based awards granted to employees and partners of the Company. In all instances of equity-based awards, compensation expense is recognized over the requisite vesting period in an amount equal to the fair value of the awards at the grant date. Equity-based compensation expense for employees and partners are included in Compensation and benefits on the Condensed Consolidated Statements of Operations and equity-based compensation expense for non-employees is included in Professional fees on the Condensed Consolidated Statements of Operations. Refer to Note 13 – Equity-Based Compensation for detail of amounts included in each financial statement line item. The Company accounts for forfeitures of awards as they occur rather than applying an estimated forfeiture rate. For an award with service-only conditions that has a graded vesting schedule, the Company recognizes the compensation cost for the entire award on a straight-line basis over the requisite service period, ensuring that the amount recognized is at least equal to the vested portion of the award at each reporting date. Non-Controlling Interests For entities that are consolidated but not 100% owned, a portion of the income or loss and equity is allocated to holders of the non-controlling interest. The aggregate of the income or loss and corresponding equity that is owned by the holders of the non-controlling interest is included in non-controlling interest in the condensed consolidated financial statements. Non-controlling interests are presented as a separate component of equity on the Condensed Consolidated Statements of Financial Condition. Net income (loss) includes the net income (loss) attributable to the holders of the non-controlling interests on the Condensed Consolidated Statements of Operations. Profits and losses of PWP OpCo are allocated to the non-controlling interests in proportion to their ownership interest regardless of their basis, with an exception for certain equity-based compensation expense which are fully attributed to non-controlling interests. Refer to Note 13 – Equity-Based Compensation for further information . Net Income (Loss) Per Share Basic net income (loss) per share is calculated by dividing net income (loss) attributable to Class A common shareholders by the weighted-average shares of Class A common shares outstanding without the consideration for potential dilutive securities. Diluted net income (loss) per share represents basic net income (loss) per share adjusted to include the potentially dilutive effect of outstanding unvested share awards, warrants, and PWP OpCo Units that are exchangeable into shares of Class A common stock on a one-for-one basis. Diluted net income (loss) per share is computed by dividing the net income attributable to Class A common shareholders by the weighted-average number of shares of Class A common stock outstanding for the period determined using the treasury stock method and if-converted method, as applicable. Recently Adopted Accounting Pronouncements No changes to U.S. GAAP that went into effect during the nine months ended September 30, 2021 had a material effect on the Company’s condensed consolidated financial statements. Future Adoption of Accounting Pronouncements No changes to U.S. GAAP that are not yet effective are expected to have a material effect on the Company’s condensed consolidated financial statements.

Business Combinations [Abstract]
Business Combination	Business Combination On June 24, 2021, the Company consummated a business combination pursuant to the Business Combination Agreement dated as of December 29, 2020, by and among the Company (previously FTIV), FinTech Investor Holdings IV, LLC a Delaware limited liability company, FinTech Masala Advisors, LLC, a Delaware limited liability company, PWP OpCo, PWP GP LLC, PWP GP, Professional Partners, and Professionals GP. Pursuant to the Business Combination Agreement, among other things, (i) FTIV acquired certain partnership interests in PWP OpCo, (ii) PWP OpCo became jointly-owned by PWP, Professional Partners and certain existing partners of PWP OpCo, and (iii) PWP OpCo now serves as the Company’s operating partnership as part of an Up-C structure. The Business Combination was treated as a reverse recapitalization transaction between entities under common control, whereby PWP OpCo was considered the accounting acquirer and predecessor entity and therefore recognized the carrying value of the net assets of FTIV as an equity contribution with no incremental goodwill or intangible assets. On December 29, 2020, concurrent with the execution of the Business Combination Agreement, FTIV also entered into subscription agreements with certain private investors (“PIPE Investors”), pursuant to which the PIPE Investors collectively subscribed for 12,500,000 shares of the Company’s Class A common stock for an aggregate purchase price equal to $ 125.0 million (the “PIPE Investment”), including $ 1.5 million subscribed by entities related to the Sponsor. The PIPE Investment was consummated concurrently with the Closing. In connection with the consummation of the Business Combination, the following occurred:  Pursuant to the Sponsor Share Surrender and Share Restriction Agreement executed concurrently with the Business Combination Agreement among the Sponsor, FTIV, PWP OpCo and certain other parties (the “ Surrender Agreement ” ), which was amended on May 4, 2021, Sponsor surrendered and forfeited to FTIV 1,023,333 shares of Class B common stock, par value $ 0.0001 per share, of FTIV;  All outstanding shares of FTIV’s Class B common stock (other than the 1,023,333 shares of FTIV Class B common stock that were forfeited by the Sponsor) were converted into shares of FTIV’s Class A common stock, and FTIV’s outstanding warrants were assumed by the Company and became exercisable for shares of Company Class A common stock on the same terms as were contained in the warrant agreements prior to the Business Combination;  FTIV acquired newly-issued common units of PWP OpCo (“PWP OpCo Units ” ) in exchange for $ 355.0 million in cash and 42,956,667 shares of Class A common stock. The cash contributed equated to the proceeds from the PIPE Investment and the outstanding cash balances and marketable securities held in a trust account of FTIV as of Closing;  FTIV issued new shares of Class B-1 common stock, which have 10 votes per share , and Class B-2 common stock, which have one vote per share , to PWP OpCo, with the Class B-1 common stock being distributed to and owned by Professional Partners and the Class B-2 common stock being distributed to and owned by ILPs, with the number of shares of such common stock issued to PWP OpCo equal the number of PWP OpCo Units that were held by Professional Partners and ILPs, respectively, following the Closing;  Professional Partners contributed the equity interests of PWP GP, the general partner of PWP OpCo, to FTIV;  PWP OpCo repaid all of its indebtedness including $ 150.0 million of Convertible Notes and $ 27.7 million of the Revolving Credit Facility, both as defined in Note 10 – Debt, as well as accrued interest and applicable premium, resulting in a Loss on debt extinguishment of $ 39.4 million ;  PWP OpCo first redeemed PWP OpCo Units held by certain electing ILPs in the amount of $ 80.5 million , and second, redeemed PWP OpCo Units held by certain electing former working partners in the amount of $ 28.6 million ; and  FTIV was renamed “Perella Weinberg Partners. ” On the date of the Closing, the Company recorded $ 22.2 million in public warrant liabilities and $ 0.7 million in private warrant liabilities. See Note 12 – Warrants for further information. In conjunction with the Business Combination, the Company incurred approximately $ 2.9 million in transaction expenses, which were recorded in Professional fees on the Condensed Consolidated Statements of Operations, as well as $ 27.6 million of offering costs which were offset against the proceeds of the Business Combination. At the time of the Closing, there were 42,956,667 shares of Class A common stock and 50,154,199 shares of Class B common stock outstanding. The number of shares of Class B common stock outstanding corresponds to the number of PWP OpCo Units attributable the Professional Partners and ILPs, which are exchangeable into PWP Class A common stock on a one-for-one basis and represent the non-controlling ownership interests in the Company. Class B-1 and B-2 common stock have de minimis economic rights. See Note 11 – Stockholders’ Equity for additional information. Concurrent with the Closing, the Company entered into certain other related agreements which are discussed further in Note 11 – Stockholders’ Equity and Note 17 – Related Party Transactions .

Revenue From Contract With Customer [Abstract]
Revenue and Receivables from Contracts with Customers	Revenue and Receivables from Contracts with Customers The services provided under contracts with clients include transaction-related advisory services, fairness opinion services, research and trading services, and underwriting services, each of which are typically identified as a separate performance obligation in contracts that contain more than one type of service. As discussed in detail below, each performance obligation meets the criteria for either over time or point in time revenue recognition. The following table disaggregates the Company’s revenue between over time and point in time recognition: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Over time $ 167,981 $ 113,246 $ 562,286 $ 314,060 Point in time 9,446 9,598 40,463 15,781 Total revenues $ 177,427 $ 122,844 $ 602,749 $ 329,841 Additionally, the Company is typically reimbursed for certain professional fees and other expenses incurred that are necessary in order to provide services to the client. These fees and related reimbursements are recorded when incurred to the relevant expense item and Revenues, respectively, in the Condensed Consolidated Statements of Operations. Reimbursable expenses billed to clients was $ 1.2 million and $ 4.0 million for the three and nine months ended September 30, 2021, respectively, and $ 0.6 million and $ 3.5 million for the three and nine months ended September 30, 2020, respectively. Transaction-Related Advisory Services The Company is contracted to provide different investment banking and advisory services that vary depending on the nature of the contract with each individual client. These transaction-related advisory services include, but are not limited to, providing financial advice and assistance in analyzing, structuring, planning, negotiating and effecting a transaction, providing financial advice with regard to a restructuring of a client’s capital structure, which may or may not result in a court-approved bankruptcy plan, and providing certain ongoing services, including research and analysis on potential targets, identifying potential investors, and financial modeling for potential transactions. Typically, the Company provides such advisory services to its clients to assist with corporate finance activities such as mergers and acquisitions, reorganizations, tender offers, leveraged buyouts, and the pricing of securities to be issued. In most circumstances, the Company considers the nature of the promises in its advisory contracts to comprise of a single performance obligation of providing advisory services to its clients. Although there may be many individual services provided in a typical contract, the individual services are not distinct within the context of the contract; rather the performance of these individual services helps to fulfill one overall performance obligation to deliver advisory services to the client. The Company recognizes revenue from providing advisory services when or as its performance obligations are fulfilled. The majority of the Company’s advisory revenue is recognized over time. However, certain performance obligations may be recognized at a point in time if the performance obligation represents a singular objective that does not transfer any notable value until formally completed, such as when issuing fairness opinions, which are further discussed below. The Company provides its advisory services on an ongoing basis, which, for example, may include evaluating and selecting one of multiple strategies. During such engagements, the Company’s clients continuously benefit from its advice as the Company is providing financial and strategic advice throughout the engagement, and, accordingly, over time revenue recognition matches the transfer of such benefits. Although the Company’s transaction-related advisory services meet the criteria for over time revenue recognition, the fee structures often involve an “all or nothing” consideration amount and the associated fees are predominantly considered variable as they are often based on the ultimate transaction value or the outcome ultimately achieved and/or are susceptible to factors outside of the Company’s influence such as third-party negotiations, regulatory approval, court approval, and shareholder votes. Accordingly, a large portion of the fees associated with these services is constrained until substantially all services have been provided, specified conditions have been met and/or certain milestones have been achieved, and it is probable that a significant revenue reversal will not occur in a future period. In some cases, a portion of the variable fees may be deferred based on the services remaining to be completed, if any (e.g., when announcement fees are earned but additional services are expected to be provided until the transaction closes). The determination of when and to what extent to recognize variable fees may require significant judgment, particularly when milestones are met near the end of a reporting period and in cases where additional services are expected to be provided subsequent to the achievement of the milestone. Fixed fees specified in the Company’s contracts, which may include upfront fees and retainers, are recognized on a systematic basis over the estimated period in which the related services are performed. Payments for transaction-related advisory services are generally due upon completion of a specified event or, for retainer fees, periodically over the course of the engagement. The Company recognizes a receivable between the date of completion of the event and payment by the client. Fairness Opinion Services Although the Company usually provides fairness opinion services in conjunction with and in the same contract as other transaction-related advisory services, fairness opinion services are considered to be a separate performance obligation in such contracts because they could be obtained separately and the Company is able to fulfill its promise to transfer transaction-related advisory services independent from its promise to provide fairness opinion services. The Company typically charges a separate, fixed fee associated with fairness opinion services that represents the standalone selling price of the fairness opinion services. The fee is recognized at the point in time at which the fairness opinion is delivered rather than over the period of time during which the services are being performed because the client does not simultaneously receive and consume the benefit of the Company’s performance to provide the fairness opinion but rather receives the benefit upon delivery of the fairness opinion itself. Payments for fairness opinion services are generally due upon delivery of the fairness opinion. The Company recognizes a receivable between the date of delivery of the fairness opinion and payment by the client. Research and Trading Services The Company provides research on the energy and related industries and related equity and commodity markets. The Company’s research clients continuously benefit from the research provided throughout arrangements between the Company and such clients, and accordingly, over time revenue recognition matches the transfer of such benefits. Recipients of this research compensate the Company for these market insights in two ways – either by direct payment (the amount of which is typically at the client’s discretion based upon the perceived value of the research services provided) or through trades directed through the Company’s trading desk (for commission generation) or through third-party commission sharing agreements. These services are sometimes referred to as “soft-dollar arrangements,” and the amount of payment is typically based on a percentage of commission income generated from the client’s trades executed by the Company. The commission per share and volume of trades are at the client’s discretion based upon the perceived value of the research services and trade execution provided. Generally, the Company does not provide trading services separate and apart from research services (i.e., clients do not typically execute trades through the Company in the normal course of business; rather, trade execution is used as a means to be compensated for research services). Because fees received for research services, and any associated trading services, are typically at the complete discretion of the client and are based on the value the client perceives in the research services provided, the entire transaction price associated with such services is variable. Accordingly, because of the broad range of possible outcomes and the inability to predict the value the client will ascribe to such services, the Company fully constrains the revenue associated with research services, and any associated trading services, until the uncertainty associated with the variable consideration is subsequently resolved, which is typically upon the earlier of receiving an invoice request from the client or receiving payment from the client. Underwriting Services Revenue associated with underwriting services includes management fees, selling concessions and underwriting fees attributable to public and private offerings of equity and debt securities. The nature of the Company’s underwriting services is raising capital on behalf of an issuer and, therefore, is typically accounted for as a single performance obligation. A separate performance obligation is identified in instances in which the contract with the client includes an over-allotment option. The Company’s underwriting services generally do not meet any of the requirements for revenue to be recognized over time, and therefore, the Company typically recognizes underwriting revenue on the pricing date of the offering, which is when the Company receives the pricing wire communication from the lead underwriter detailing the underwriting fees to which the Company is entitled. Similarly, the performance obligation associated with the over-allotment is satisfied at the point in time at which the option is exercised. The Company’s role in underwriting commitments is usually as a co-manager or passive bookrunner, rather than as the lead underwriter. Accordingly, the Company estimates its share of transaction-related expenses incurred by the underwriting syndicate on the pricing date of the offering and presents these expenses gross within Travel and related expenses in the Condensed Consolidated Statements of Operations. Such amounts are adjusted to reflect actual expenses in the period in which the Company receives the final settlement, typically within 90 days following the closing of the transaction. Contract Costs Incremental costs of obtaining a contract are expensed as incurred as such costs are generally not recoverable. Costs to fulfill contracts consist of out-of-pocket expenses that are part of performing transaction-related advisory services and are typically expensed as incurred as these costs are related to performance obligations that are satisfied over time. Remaining Performance Obligations and Revenue Recognized from Past Performance As of September 30, 2021, the aggregate amount of the transaction price allocated to performance obligations yet to be satisfied is $ 7.0 million and the Company generally expects to recognize this revenue within the next twelve months . Such amounts primarily relate to the Company’s performance obligations of providing transaction-related advisory services and fairness opinion services. The Company recognized revenue of $ 53.5 million and $ 309.0 million during the three and nine months ended September 30, 2021, respectively, and $ 39.3 million and $ 147.5 million during the three and nine months ended September 30, 2020, respectively, related to performance obligations that were satisfied or partially satisfied in prior periods, mainly due to constraints on variable consideration in prior periods being resolved for transaction-related advisory services. Contract Balances The timing of revenue recognition may differ from the timing of payment. The Company records a receivable when revenue is recognized prior to payment and the Company has an unconditional right to payment. The Company records deferred revenue (otherwise known as contract liabilities) when it receives fees from clients that have not yet been earned or when the Company has an unconditional right to consideration before all performance obligations are complete (e.g., receipt of certain announcement, retainer or upfront fees before the performance obligation has been fully satisfied). As of September 30, 2021 and December 31, 2020, the Company recorded $ 5.9 million and $ 10.6 million , respectively, for these contract liabilities which are presented as Deferred revenue on the Condensed Consolidated Statements of Financial Condition. For the nine months ended September 30, 2021 and 2020, $ 9.6 million and $ 1.6 million , respectively, of the respective beginning deferred revenue balance was recognized as revenue and was primarily related to transaction-related advisory services performance obligations that are recognized over time. Allowance for Credit Losses The allowance for credit losses activity for the three and nine months ended September 30, 2021 and 2020 is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Beginning balance (1) $ 1,104 $ 1,087 $ 1,045 $ 1,923 Bad debt expense 916 3,099 290 2,853 Write-offs ( 18 ) ( 38 ) ( 46 ) ( 596 ) Recoveries - 197 710 197 Foreign currency translation and other adjustments ( 1 ) ( 18 ) 2 ( 50 ) Ending balance $ 2,001 $ 4,327 $ 2,001 $ 4,327 (1) Beginning balance for the nine months ended September 30, 2020 includes the cumulative adjustment of $ 0.2 million , which reflects the increase in the Company’s allowance for credit losses upon adoption of ASU 2016-13 and the CECL model on January 1, 2020.

Leases [Abstract]
Leases	Leases The Company leases office space and certain office equipment under operating lease agreements. The Company determines if an arrangement or contract is a lease at inception and does not separate lease and non-lease components of the contract. The Company records the present value of its commitments for leases with terms of more than one year on the Condensed Consolidated Statements of Financial Condition as a right-of-use asset with the corresponding liability. Right-of-use assets are subject to certain adjustments for lease incentives, deferred rent and initial direct costs. The Company elected the practical expedient not to separate lease components and non-lease components in calculating the net present value of the lease payments on office space and office equipment leases. Thus, the measurement of the right-of-use asset and corresponding lease obligation use one single combined component. All leases were determined to be operating leases. Right-of-use assets represent the Company’s right to use the underlying assets for their lease terms and lease liabilities represent the Company’s obligation to make lease payments arising from these leases. The Company’s lease agreements do not contain any residual value guarantees. Lease expense is recognized on a straight-line basis over the lease term for new leases and over the remaining lease term for existing leases already in place at January 1, 2019 (date of adoption). The implicit discount rates used to determine the present value of the Company’s leases are not readily determinable, thus, the Company uses its incremental borrowing rate to determine the present value of its lease payments. The determination of an appropriate incremental borrowing rate requires significant assumptions and judgement. The Company’s incremental borrowing rate was calculated based on the Company’s recent debt issuances and market conditions at the time of adoption or upon entering into a new lease, as applicable. The Company weights the rates appropriately depending on the term of the leases. Renewal and termination terms of the Company’s leases vary depending on the lease. The Company estimates the expected lease terms by assuming the exercise of renewal options and extensions where an economic penalty exists that would preclude the abandonment of the lease at the end of the initial non-cancelable term and the exercise of such renewal or extension is at the sole discretion of the Company. Certain lease agreements are secured by security deposits, which are reflected in Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. In conjunction with the Separation, the Company entered into sublease agreements for portions of its Houston and New York office spaces with the Asset Management business through 2027 and 2022, respectively. These subleases are considered operating leases. The subleases do not include renewal options and the Company has the right to terminate these subleases for any reason after giving 90 days prior written notice. Sublease income is recognized on a straight-line basis over the term of the lease. The Company elected the practical expedient not to separate lease components and non-lease components for these subleases. See additional information regarding these subleases in Note 17 – Related Party Transactions. In May 2021, the Company extended the term of its New York office lease by five months , which resulted in an increase to Lease liabilities and a corresponding increase to Right-of-use lease assets of $ 5.1 million .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The following table summarizes the Company’s tax position for the periods presented: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Income (loss) before income taxes $ ( 9,312 ) $ ( 95 ) $ 24,740 $ ( 24,740 ) Income tax benefit (expense) $ ( 150 ) $ ( 974 ) $ ( 2,695 ) $ ( 2,518 ) Effective income tax rate ( 1.61 %) ( 1,025.26 %) 10.89 % ( 10.18 %) The Company’s income tax provision and the corresponding annual effective tax rate are based on projected U.S. GAAP income and the currently enacted statutory tax rates in the various jurisdictions in which the Company operates. For interim reporting, the Company estimates the annual effective tax rate based on projected income for the full year and records a quarterly tax provision in accordance with the annual effective tax rate. The Company’s effective tax rate is dependent on many factors, including the estimated amount of income subject to tax. Consequently, the effective tax rate can vary from period to period. The Company’s overall effective tax rate in each of the periods described above varies from the U.S. federal statutory rate primarily because (i) the Company was not subject to U.S. federal corporate income taxes prior to the Business Combination, (ii) a portion of equity-based compensation expense is non-deductible, both prior to the Business Combination and for the subsequent period and (iii) a portion of the Company’s income is allocated to non-controlling interests held in PWP OpCo in which the majority of any tax liability on such income is borne by the holders of such non-controlling interests and reported outside of the condensed consolidated financial statements. The Business Combination resulted in a $ 16.1 million increase to the Company’s deferred tax asset primarily related to a step-up in the tax basis of certain assets that will be recovered as those assets are amortized. The remaining $ 2.3 million of the deferred tax asset balance as of September 30, 2021 is related to local and foreign income taxes in addition to the corporate income taxes resulting from the Business Combination. The Company evaluates the realizability of its deferred tax asset on a quarterly basis and adjusts the valuation allowance when it is more-likely-than-not that all or a portion of the deferred tax asset may not be realized. Management has recorded a partial valuation allowance related to the outside partnership basis of its investment in PWP OpCo for the amount of the deferred tax asset that is not expected to be realized. The Company believes it is more-likely-than-not that the remaining net deferred tax asset recorded as of September 30, 2021 will be recovered in the future based on all available positive and negative evidence. In connection with the step-up in tax basis generated on the day of the Business Combination, the Company has recorded a payable of $ 14.1 million pursuant to the terms of the tax receivable agreement. As of September 30, 2021 , the Company has no t recorded any unrecognized tax benefits associated with uncertain tax positions. The Company does not expect there to be any material changes to uncertain tax positions within 12 months of the reporting date.

Convertible Notes The Company issued 7.0 % subordinated unsecured convertible notes with an aggregate principal amount of $ 150.0 million (the “Convertible Notes”) under a Note Purchase Agreement (as amended, the “NPA”) executed on November 30, 2016. The Convertible Notes were due to mature on November 30, 2026 (the “Maturity Date”) unless earlier converted or repaid pursuant to the terms of the NPA. The estimated intrinsic value of the Beneficial Conversion Feature (“BCF”) as of issuance was $ 32.7 million , which was recognized as a discount on the Convertible Notes with an offsetting increase to Partners’ capital. The BCF discount was amortized to interest expense using the effective interest method based on the Maturity Date. Certain of the persons who held Convertible Notes (each herein referred to as a “Holder”) are partners. Refer to Note 17 – Related Party Transactions for further information. In December 2020, the Company entered into letter agreements (the “2020 Letter Agreements”) with all Holders, which amended and restated any existing letter agreements, pursuant to which all of the holders (the “Redeeming Holders”) agreed to collectively tender for redemption $ 150.0 million aggregate principal amount of their Convertible Notes (such Convertible Notes, the “Redeemed Notes”) for cash. Pursuant to the terms of the 2020 Letter Agreements, the Redeeming Holders agreed not to convert their Convertible Notes in connection with the Business Combination. Upon consummation of the Business Combination, the Company redeemed the Convertible Notes for $ 161.6 million , which included the total outstanding $ 150.0 million aggregate principal, an applicable premium for Redeeming Holders owning at least $ 5.0 million of principal, and accrued and unpaid interest. The Company recognized a $ 39.4 million loss on extinguishment of the Convertible Notes composed of the $ 10.9 million premium and $ 28.5 million of unamortized debt discount and issuance costs. Debt Discount and Issuance Costs – A portion of the Convertible Notes was issued at a 5.0 % original issue discount in the amount of $ 5.8 million coupled with a 3.0 % commitment fee in the amount of $ 3.5 million . In addition to the discount and commitment fees, the Company incurred debt issuance costs of approximately $ 1.1 million . The debt discounts and original issuance costs were amortized using the effective interest method over the term of the Convertible Notes. The effective interest rate of the Convertible Notes, considering the cash coupon rate of 7.0% as well as amortization of the BCF discount, debt discount and issuance costs, was 11.95 % for the period from January 1, 2021 through June 24, 2021 (the date such Convertible Notes were redeemed) as well as for the three and nine months ended September 30, 2020. The aggregate interest expense related to the Convertible Notes was $ 6.9 million for the period from January 1, 2021 through June 24, 2021 and $ 3.5 million and $ 10.5 million during the three and nine months ended September 30, 2020, respectively. Revolving Credit Facility On November 30, 2016, the Company entered into a credit agreement (as amended, the “Credit Agreement”) with Cadence Bank, N.A. (“Cadence Bank”). In December 2018, the Company amended the Credit Agreement to modify a term loan to a revolving credit facility with a line of credit of $ 50.0 million (the “Revolving Credit Facility”). During the nine months ended September 30, 2020, the Company made principal payments on the Revolving Credit Facility of $ 32.0 million as well as drawdowns of $ 22.0 million . Applicable only to the period after the Separation and before the Business Combination, the Credit Agreement named PWP Capital Holdings LP as a guarantor of the Revolving Credit Facility and required that financial covenants be determined on a combined basis with the results of both the Company and PWP Capital Holdings LP for the applicable periods ended. Upon consummation of the Business Combination, the Company repaid all of the outstanding borrowings under the Credit Agreement, which included $ 27.7 million principal amount plus accrued and unpaid interest. In anticipation of the Closing, on June 15, 2021, the Credit Agreement was amended such that as of the Closing Date, (i) the maturity was extended from April 1, 2022 to July 1, 2025, (ii) interest accrues at LIBOR plus a fixed rate of 2.00 % per annum (with a 0.25 % LIBOR floor) with an alternate base rate option equal to Cadence Bank’s prime rate minus 1.00 % (with a 3.25 % floor), (iii) up to $ 15.0 million of the Revolving Credit Facility may be used for the issuance of letters of credit, (iv) up to $ 20.0 million of incremental revolving commitments may be incurred under the Credit Agreement, and (v) certain financial covenants were amended. As of September 30, 2021 , the Company had no outstanding balance related to the Revolving Credit Facility and no incremental revolving commitments were incurred. The weighted average interest rate for the Revolving Credit Facility was 2.62 % for the period from January 1, 2021 through June 24, 2021 (the Closing Date) and 2.72 % and 3.10 % for the three and nine months ended September 30, 2020, respectively. Debt Issuance Costs – Prior to the Business Combination, the Company incurred $ 1.8 million in issuance costs related to the Credit Agreement, which were amortized to Interest expense using the effective interest method over the life of the Revolving Credit Facility. The effective interest rate of the Revolving Credit Facility, taking into account these issuance costs, was 3.73 % for the period from January 1, 2021 through June 24, 2021 and 3.67 % and 3.95 % for the three and nine months ended September 30, 2020, respectively. The amendments described above were accounted for as modifications as opposed to a debt extinguishment in accordance with U.S. GAAP. As such, the unamortized original debt issuance costs as well as the additional $ 0.4 million in fees incurred to amend the facility are being amortized using the effective interest method to Interest expense over the amended remaining term of the Revolving Credit Facility. Interest expense related to the Revolving Credit Facility was $ 0.1 million and $ 0.6 million during the three and nine months ended September 30, 2021, respectively, and $ 0.4 million and $ 1.3 million during the three and nine months ended September 30, 2020 , respectively.

Class B Common Stock The Company has two classes of Class B common stock: Class B-1 common stock and Class B-2 common stock. Holders of Class B common stock are entitled to receive ratably, in proportion to the number of shares held, dividends of the same type as any dividends and other distributions in cash, stock or property of PWP payable or to be made on outstanding shares of Class A common stock in an amount per share of Class B common stock equal to the amount of such dividends or other distributions as would be made on 0.001 shares of Class A common stock. Additionally, the holders of shares of Class B common stock are entitled to receive on a pari passu basis with the holders of the Class A common stock, such dividend or other distribution on the Class A common stock when, as, and if declared by the Board of Directors out of our assets or legally available funds. Each holder of Class B-1 common stock shall be entitled to ten votes for each share of Class B-1 common stock held of record by such holder for so long as the Professional Partners directly or indirectly maintain units that represent at least ten percent of issued and outstanding Class A common stock (the “10% Condition”).

Non-Controlling Interests Non-controlling interests represents the ownership interests in PWP OpCo held by holders other than Perella Weinberg Partners. Professional Partners and the ILPs own 50,154,199 PWP OpCo Units as of September 30, 2021, which represent a 54.11 % non-controlling ownership interest in PWP OpCo. These PWP OpCo Units are exchangeable into PWP Class A common stock on a one-for-one basis. Class B-1 and Class B-2 common stock have de minimis economic rights. Registration Rights Agreement In connection with the Closing, the Company entered into a registration rights agreement with the Sponsor, Professional Partners and the ILPs pursuant to which the Company is required to file with the SEC a registration statement pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”) registering the resale of certain shares of its Class A common stock and certain of its other equity securities. The Company will bear the expenses incurred in connection with the filing of any registration statements filed pursuant to the registration rights agreement. The registration rights agreement does not contain any penalties associated with failure to file or to maintain the effectiveness of a registration statement covering the shares owned by individuals covered by such agreement. Sponsor Share Surrender and Share Restriction Agreement Concurrent with the Business Combination Agreement, FTIV, PWP OpCo and certain other parties entered into the Surrender Agreement with the Sponsor, which was amended on May 4, 2021, under which the founder shares and Placement Shares owned by the Sponsor are subject to transfer restrictions that lapse in tranches based on share price targets or the 10 year anniversary, whichever occurs first. Additionally, if, prior to the fourth anniversary of the Closing, the closing share price is greater than $ 12.00 per share or $ 15.00 per share for any 20 trading days out of 30 consecutive trading days (each a “Trigger Date”), then, during the 15 day period following such Trigger Date, the Company shall have the right to purchase from the Sponsor up to an aggregate of 1,000,000 founder shares per Trigger Date for a purchase price of $ 12.00 per share or $ 15.00 per share, respectively, by providing written notice of such repurchase election to the Sponsor. On August 9, 2021, the Company repurchased 1,000,000 founder shares from the Sponsor at a purchase price of $ 12.00 per share for a total purchase price of $ 12.0 million . The share repurchase was recorded to Treasury stock, at cost, on our Condensed Consolidated Statements of Financial Condition as of September 30, 2021. Stockholder Agreement On the date of the Closing, PWP and Professional Partners entered into a Stockholders Agreement (the “Stockholders Agreement”), providing for certain approval and director nomination rights in favor of Professional Partners. The Stockholders Agreement provides that for so long as Professional Partners or its limited partners as of the date of the Closing (or their permitted successors or assigns) continue to hold securities representing at least five percent of the Company’s outstanding Class A common stock on an as-exchanged basis (the “5% Condition”), the Board may not approve, absent the prior consent of Professional Partners, any amendment to the certificate of incorporation or bylaws of the Company, or the limited partnership agreement of PWP OpCo, in each case, that would materially and adversely affect in a disproportionate manner the rights of Professional Partners or its limited partners. In addition, for so long as the 10% Condition is met, the Board may not approve, absent the prior consent of Professional Partners, a number of ordinary course operating activities in respect of the Company, PWP OpCo and PWP OpCo’s subsidiaries. The effect of the agreement is that Professional Partners may maintain control over the Company’s significant corporate transactions even if it holds less than a majority of the combined total voting power of the Class A and Class B common stock. The Stockholders Agreement will terminate once the 5 % Condition is no longer satisfied. PWP OpCo Limited Partnership Agreement Governance and Voting and Economic Rights On the date of the Closing, PWP OpCo adopted an Amended and Restated Agreement of Limited Partnership of PWP OpCo (as amended, restated, modified or supplemented from time to time, the “PWP OpCo LPA”). Through the Company’s control of PWP GP, the general partner of PWP OpCo, the Company will have unilateral control (subject to the consent of PWP OpCo’s partners on certain limited matters) over the affairs and decisions of PWP OpCo, including the appointment of officers of PWP OpCo. As such, including through such officers and directors, the Company will be responsible for all operational and administrative decisions of PWP OpCo and the day-to-day management of PWP OpCo’s business. Furthermore, PWP GP cannot be removed as the general partner without the Company’s approval. No holders of PWP OpCo Units (the “PWP OpCo Unitholders”), in their capacity as such, will have any authority or right to control the management of PWP OpCo or to bind it in connection with any matter. However, Professional Partners, which is ultimately managed by a committee of limited partners that manages Professionals GP, the general partner of Professional Partners, will have the ability to exercise majority voting control over the Company by virtue of its ownership of all outstanding shares of Class B-1 common stock. In accordance with the PWP OpCo LPA, the Company intends to use best efforts to cause PWP OpCo to make sufficient cash distributions to the PWP OpCo Unitholders to fund their tax obligations in respect of the income of PWP OpCo that is allocated to them. Generally, these tax distributions will be computed based on the Company’s estimate of the net taxable income of PWP OpCo allocable to such holder of partnership units multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate prescribed for an individual or corporation (taking into account the non-deductibility of certain expenses and the character of PWP OpCo’s income). Exchange Rights In accordance with the PWP OpCo LPA, PWP OpCo Unitholders (other than the Company) may exchange these units for (i) shares of Class A common stock on a one-for-one basis or (ii) cash from an offering of shares of Class A common stock with the form of consideration determined by the Company. Concurrently with an exchange of PWP OpCo Units for shares of Class A common stock or cash by a PWP OpCo Unitholder who also holds shares of Class B common stock, such PWP OpCo Unitholder will be required to surrender to us a number of shares of Class B common stock equal to the number of PWP OpCo Units exchanged, and such shares will be converted into shares of Class A common stock or cash (at our option) which will be delivered to such PWP OpCo Unitholder (at our option) at a conversion rate of 0.001 . The PWP OpCo LPA contains restrictions on the ability to exchange PWP OpCo Units for shares of Class A common stock or cash from an offering of shares of Class A common stock, for the following periods: (i) PWP OpCo Units held by Professional Partners will be subject to a restriction for time periods that are fully back-to-back with the lock-up periods contemplated in the amended and restated limited partnership agreement of Professional Partners (generally speaking, such lock-up periods (a) for former working partners, will be 180 days after Closing; and (b) for working partners, will be between three to five years after the Closing), (ii) PWP OpCo Units held by ILPs existing at the time of the Business Combination will be subject to such restriction for 180 days after the Closing, and (iii) any other outstanding PWP OpCo Units not previously covered by clauses (i) and (ii) above will be subject to such restriction for a period of twelve months following the date on which such PWP OpCo Units were acquired. PWP GP may waive, and in certain cases has waived, the foregoing restrictions for any holder with respect to all or a portion of such holder’s units, with no obligation to do so for any other holder.

No public warrant will be exercisable and the Company will not be obligated to issue any shares to holders seeking to exercise their Public Warrants, unless the issuance of the shares upon such exercise has been registered, qualified or deemed exempt under the securities laws of the state of residence of the exercising holder. The Company filed a registration statement under the Securities Act with the SEC on July 15, 2021 which was declared effective July 26, 2021. It is the Company’s responsibility to maintain the effectiveness of such registration statement and a current prospectus related thereto, until the expiration of the public warrants in accordance with the provisions of the warrant agreement. Notwithstanding the above, if the shares of Class A common stock are, at the time of any exercise of a public warrant, not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of public warrants who exercise their public warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Once the warrants become exercisable, the Company may call the warrants for redemption as follows: (i) in whole and not in part; (ii) at a price of $ 0.01 per warrant; (iii) upon a minimum of 30 days ’ prior written notice of redemption to each warrant holder; and (iv) if, and only if, the last reported sale price of the Class A common stock equals or exceeds $ 18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 -trading day period ending on the third day prior to the date on which the Company sends the notice of redemption to the warrant holders. If the Company calls the public warrants for redemption for cash, management will have the option to require any holder that wishes to exercise the public warrants to do so on a “cashless basis” as described in the warrant agreement. The exercise price and number of shares of Class A common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. Additionally, in no event will the Company be required to net cash settle the warrants. Warrant holders do not have the rights or privileges of holders of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders. As of September 30, 2021, the Company had 7,666,642 public warrants outstanding. Private Warrants The private warrants are identical to the public warrants, except that the private warrants and the Class A common stock issuable upon the exercise of the private warrants will not be transferable, assignable or saleable until 30 days after the completion of the Business Combination, subject to certain limited exceptions. Additionally, the private warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees. If the private warrants are held by someone other than the Sponsor or its permitted transferees, the private warrants will be redeemable by the Company and exercisable by such holders on the same basis as the public warrants. As of September 30, 2021, the Company had 203,333 private warrants outstanding. Valuation of Warrants The public and private warrants meet the definition of a derivative under ASC 815 and as such, the Company recorded these warrants as liabilities at fair value upon the closing of the Business Combination in accordance with ASC 820 with subsequent changes in their respective fair values recorded in Change in fair value of warrant liabilities on the Condensed Consolidated Statements of Operations. See Note 16 – Fair Value Measurements and Investments for description of the valuation methodology and further information. Exercise of Warrants On September 29, 2021, all of the public and private warrants became exercisable. As of September 30, 2021 , no ne of the warrants were exercised.

Share-based Payment Arrangement [Abstract]
Equity-Based Compensation	Equity-Based Compensation PWP Omnibus Incentive Plan Awards Concurrent with the Business Combination, the Company adopted the Perella Weinberg Partners 2021 Omnibus Incentive Plan (the “PWP Incentive Plan”), which establishes a plan for the granting of incentive compensation awards measured by reference to PWP Class A common stock. Under the PWP Incentive Plan, the Company may grant options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance restricted stock units (“PSUs”), stock bonuses, other stock-based awards, cash awards or any combination of the foregoing. The maximum aggregate number of shares of Class A common stock reserved for issuance under the PWP Incentive Plan for general purposes (the “General Share Reserve”) is 13,980,000 shares and will be increased on the first day of each fiscal year of the Company beginning in calendar year 2022 by the number of shares of Class A common stock equal to the excess, if any, of (i) 15 % of the number of outstanding shares of Class A common stock and the outstanding PWP OpCo Units that are exchangeable for shares of Class A common stock, in each case, on last day of the immediately preceding fiscal year, over (ii) the number of shares of Class A common stock reserved and available for issuance in respect to future grants of awards under the PWP Incentive Plan as of the last day of the immediately preceding fiscal year. In addition to the General Share Reserve, 10,200,000 shares of Class A common stock (the “Transaction Pool Share Reserve”) are reserved for issuance under the plan through the one-year anniversary of the Business Combination, of which (i) up to 7,000,000 shares are reserved for Transaction Pool RSUs (defined below) and (ii) 3,200,000 shares are reserved for Transaction Pool PSUs (defined below). The Company intends to use newly issued shares of PWP Class A common stock to satisfy vested awards under the PWP Incentive Plan. Certain employees in France and Canada receive dividend equivalents in the form of additional awards that have the same vesting terms as the original underlying awards. These additional dividend equivalent awards are granted from the General Share Reserve. Awards granted from the General Share Reserve that are subsequently forfeited, cancelled, exchanged, surrendered, terminated or expired are available for future grant. However, awards granted from the Transaction Pool Share Reserve that are subsequently forfeited, cancelled, exchanged, surrendered, terminated or expired are not available for future grant. As of September 30, 2021, 3,965,271 total shares remained reserved and available for future issuance under the PWP Incentive Plan. Business Combination Awards During the third quarter of 2021, in connection with the Business Combination, the Company granted awards in the form of (i) restricted stock units out of the Transaction Pool Reserve consisting of (a) PSUs that only vest upon the achievement of both service and market conditions out of the Transaction Pool Share Reserve (“Transaction Pool PSUs”) and (b) RSUs that vest upon the achievement of service conditions out of the Transaction Pool Share Reserve (“Transaction Pool RSUs”) as well as (ii) PSUs out of the General Share Reserve to certain executives that vest upon the achievement of both service and market conditions (“Management PSUs”). Transaction Pool PSUs — The service condition requirement with respect to the Transaction Pool Performance RSUs is generally satisfied over three to five years , with 20 % of the awards vesting on each of the 36, 42, 48, 54 and 60 month anniversaries of the grant date. The market condition requirement will be satisfied in 25 % increments upon the publicly traded shares of Class A common stock achieving closing share prices equal to $12, $13.50, $15 and $17 for any 20 trading days out of any 30 consecutive trading days ending prior to the sixth anniversary of the grant date. As of September 30, 2021 , the $ 12 and $ 13.50 market condition requirements were satisfied. The following table summarizes activity related to unvested Transaction Pool PSUs for the nine months ended September 30, 2021: Transaction Pool PSUs Weighted Average Grant Date Fair Value Per Share Balance at January 1, 2021 - - Granted (1) 3,202,616 $ 12.74 Vested - - Forfeited - - Balance at September 30, 2021 3,202,616 $ 12.74 (1) Includes dividend equivalents that have been awarded in the form of additional Transaction Pool PSUs that were granted from the General Share Reserve. The grant date fair value of the Transaction Pool PSUs granted during both the three and nine months ended September 30, 2021 was $ 40.8 million . As of September 30, 2021, total unrecognized compensation expense related to unvested Transaction Pool PSUs was $ 39.8 million , which is expected to be recognized over a weighted average period of 3.92 years. The Company estimated the fair value of the Transaction Pool PSUs on the grant date using a Monte-Carlo simulation valuation model. The following table presents the assumptions used for the Transaction Pool PSUs for the nine months ended September 30, 2021: Nine Months Ended September 30, 2021 Risk-free interest rate 0.93 % Dividend yield 2.00 % Volatility factor 32.90 % Transaction Pool RSUs — The Transaction Pool RSUs generally vest in equal annual installments over the requisite service period of three years . The grant date fair value of the Transaction Pool RSUs granted during both the three and nine months ended September 30, 2021 was $ 97.6 million . As of September 30, 2021, total unrecognized compensation expense related to unvested Transaction Pool RSUs was $ 75.4 million , which is expected to be recognized over a weighted average period of 2.48 years. The following table summarizes activity related to unvested Transaction Pool RSUs for the nine months ended September 30, 2021: Transaction Pool RSUs Weighted Average Grant Date Fair Value Per Share Balance at January 1, 2021 - - Granted (1) 6,987,274 $ 13.97 Vested ( 1,107,279 ) 13.97 Forfeited ( 28,678 ) 13.97 Balance at September 30, 2021 5,851,317 $ 13.97 (1) Includes dividend equivalents that have been awarded in the form of additional Transaction Pool RSUs that were granted from the General Share Reserve. Certain employee offer letter awards, that were previously accounted for as liability awards due to a cash settlement option, have been settled using Transaction Pool RSUs. This settlement was treated as a modification of the award, and as such, the liability balance of $ 3.9 million as of t he RSU grant date was reclassified from Accounts payable, accrued expenses and other liabilities to Additional paid-in capital on the Condensed Consolidated Statement of Financial Condition as of September 30, 2021. Management PSUs — The service condition requirement with respect to the Management PSUs is generally satisfied in two equal installments subject to continued employment on the third and fifth anniversaries of the grant date. The market condition is satisfied upon the achievement of closing stock prices equal to $ 15 , $ 20 , $ 25 and $ 30 for 20 out of any 30 consecutive trading days prior to the fifth anniversary of the grant date, as measured on the last calendar day of each month, subject to linear interpolation between the applicable price points. The following table summarizes activity related to unvested Management PSUs for the nine months ended September 30, 2021: Management PSUs Weighted Average Grant Date Fair Value Per Share Balance at January 1, 2021 - - Granted 9,500,000 $ 8.86 Vested - - Forfeited - - Balance at September 30, 2021 9,500,000 $ 8.86 The weighted average grant date fair value of the Management PSUs granted during both the three and nine months ended September 30, 2021 was $ 84.2 million . As of September 30, 2021, total unrecognized compensation expense related to unvested Management PSUs was $ 82.3 million , which is expected to be recognized over a weighted average period of 3.92 years. The Company estimated the fair value of the Management PSUs on the grant date using a Monte-Carlo simulation valuation model. The following table presents the assumptions used for the Management PSUs for the nine months ended September 30, 2021: Nine Months Ended September 30, 2021 Risk-free interest rate 0.77 % Dividend yield 2.00 % Volatility factor 32.41 % General Awards On August 31, 2021, the Company granted RSU awards out of the General Share Reserve that vest upon the achievement of service conditions (the “General RSUs”). The Company expects to grant General RSUs from time to time in the ordinary course of business. The General RSUs vest over the requisite service period, which is generally one to five years . The grant date fair value of the General RSUs granted during both the three and nine months ended September 30, 2021 was $ 7.3 million . As of September 30, 2021, total unrecognized compensation expense related to unvested General RSUs was $ 6.9 million which is expected to be recognized over a weighted average period of 2.84 years. The following table summarizes activity related to unvested General RSUs for the nine months ended September 30, 2021: General RSUs Weighted Average Grant Date Fair Value Per Share Balance at January 1, 2021 - - Granted 524,917 $ 13.97 Vested - - Forfeited - - Balance at September 30, 2021 524,917 $ 13.97 Voting and Dividend Equivalent Rights Grantees of the Company’s RSUs and PSUs have no rights as stockholders with respect to the right to vote or the right to receive dividends prior to the date that the underlying shares are issued. If during the period commencing on the grant date and ending on the date the underlying shares are issued, the Company declares a dividend on its shares, then the grantee shall be eligible to receive such dividends on or about the date such shares are issued. Certain employees in France and Canada receive dividends in the form of award grants that match the underlying award from which the dividends were generated. The remaining employees receive such awards in the form of cash. Legacy Awards and Professional Partners Awards Prior to the Business Combination, Professional Partners granted certain equity-based awards to partners providing services to PWP OpCo (the “Legacy Awards”). In January 2020, the Company granted Legacy Awards with a grant-date fair value of $ 6.4 million , which was estimated using the income approach and assumed a range of discount rates between 3.8 % and 11.2 % . In January 2021, the Company granted Legacy Awards with a grant-date fair value of $ 9.3 million , which was estimated using the income approach and assumed a range of discount rates between 2.0 % and 9.8 % . Under the income approach, fair value is determined by converting future projected cash flows to a single present value amount (discounted) using current expectations about those future cash flows. In connection with the Business Combination and a related internal reorganization of Professional Partners, an ownership structure was implemented that includes a class of partnership units that allocates increases in value and income and distributions on a pro-rata basis to all holders of such partnership units in accordance with their ownership interests. Pursuant to the internal reorganization, existing Legacy Awards were canceled and replaced by converting each limited partner’s capital interests in Professional Partners attributable to PWP OpCo into a combination of original capital units (“OCUs”), value capital units (“VCUs”), and/or alignment capital units (“ACUs”). The OCUs are held by current limited partners of Professional Partners based on a pro-rata allocation of their existing capital and were fully vested upon recapitalization. The VCUs and ACUs (collectively, “Professional Partners Awards”) are held by current working partners and require services to be performed on behalf of PWP OpCo. The Professional Partners Awards are generally subject to a service-based graded vesting schedule over a three to five -year period. Fully vested Professional Partners Awards are exchangeable for PWP OpCo Units and allow for their exchange into Class A common stock of PWP on a one-for-one basis. Holders of Professional Partners Awards and OCUs are entitled to participate in distributions made on PWP OpCo Units underlying their Professional Partners Awards during the vesting period. The Company accounted for the cancellation of the Legacy Awards and concurrent grant of Professional Partners Awards as a modification of the Legacy Awards. The fair value of the Professional Partners Awards granted was determined to be incremental value conveyed to the holders of the Legacy Awards and will be accounted for under ASC 718, Compensation—Stock Compensation , with the cost reflected in equity-based compensation over the requisite service period. The Company will continue to amortize the unrecognized cost associated with the Legacy Awards over its original vesting schedule. The $ 301.5 million grant-date fair value of the Professional Partners Awards is based on the closing price of PWP Class A common stock on the date of grant as units in Professional Partners are ultimately exchangeable into shares of PWP Class A common stock on a one-for-one basis. The vesting of Professional Partners Awards does not dilute Perella Weinberg Partners shareholders relative to Professional Partners as Professional Partners’ interest in PWP OpCo does not change as a result of granting those equity awards to its working partners. As a result, all of the compensation expense and corresponding capital contribution associated with the Professional Partners Awards, as well as the remaining compensation expense related to the Legacy Awards, is allocated to non-controlling interests on the Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Financial Condition. If any Professional Partners Award is forfeited, the value attributable to the forfeited Professional Partners Award will accrete to all limited partners in Professional Partners based on relative ownership at the time of forfeiture. The accretion of value upon forfeiture reflects a reallocation of value attributable to the forfeited Professional Partners Award and does not result in an incremental grant. On August 31, 2021, certain Professional Partner ACUs and VCUs held by French partners were canceled, and an equal number of Transaction Pool PSUs were issued to such partners. The Company accounted for these transactions as a modification. The grant-date fair value of the Transaction Pool PSUs was based on the closing price of PWP Class A common stock on the date of grant. The total expense associated with the replacement awards will be amortized over the remaining service period for Transaction Pool PSUs. The canceled Professional Partner Awards were reallocated to certain other working partners on August 31, 2021, and the Company accounted for these as a new grant of ACUs and VCUs. The grant date fair value of these awards was $ 11.5 million which was based on the closing price of PWP Class A common stock on the date of grant. As of September 30, 2021, there was $ 28.4 million of unrecognized compensation cost associated with the Legacy Awards that is expected to be recognized over a weighted-average period of 1.82 years. As of September 30, 2021, there was $ 285.8 million of unrecognized compensation expense related to unvested Professional Partners Awards, which is expected to be recognized over a weighted-average period of 4.62 years. The following table presents the expense related to awards that were recorded in Professional fees and components of Equity-based compensation included on the Condensed Consolidated Statements of Operations: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Professional fees PWP Incentive Plan Awards $ 177 $ - $ 177 $ - Total Professional fees $ 177 $ - $ 177 $ - Equity-based compensation PWP Incentive Plan Awards $ 20,917 $ - $ 20,917 $ - Legacy Awards (1) 1,450 6,120 13,615 18,484 Professional Partners Awards (1) 15,683 - 16,740 - Total Equity-based compensation $ 38,050 $ 6,120 $ 51,272 $ 18,484 Income tax benefit of equity-based awards $ 2,351 $ - $ 2,351 $ - (1) The vesting of these awards does not dilute Perella Weinberg Partners shareholders relative to Professional Partners. As such the related equity-based compensation expense is fully attributed to non-controlling interests.

Compensation Related Costs [Abstract]
Other Compensation and Benefits	Other Compensation and Benefits Compensation and benefits includes, but is not limited to, salaries, bonuses (discretionary awards and guaranteed amounts), severance and deferred compensation. In all instances, compensation expense is accrued over the requisite service period. Deferred Compensation Programs The Company has various deferred compensation plans. Some plans allow employees to defer cash payments for services performed in the past and some plans require future service. The Company recognizes compensation expense over the requisite service period. In addition, certain legacy plans required the Company to invest the deferred amounts into designated brokerage accounts at the employee’s discretion, while others allowed employees to make hypothetical investments in which their deferrals were deemed to be invested. The designated brokerage balances are reflected in Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. The Company maintains company-owned life insurance policies which are designed to offset a portion of the liability for the hypothetical investments of these legacy plans. The cash surrender value of these life insurance policies is also included in Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. Deferred compensation liabilities will be paid at various intervals through 2025 and are presented within Deferred compensation programs on the Condensed Consolidated Statements of Financial Condition. Compensation expenses related to these deferred compensation plans was $ 0.3 million and $ 1.0 million for the three and nine months ended September 30, 2021, respectively, and $ 1.6 million and $ 4.6 million for the three and nine months ended September 30, 2020, respectively, and are presented within Compensation and benefits in the Condensed Consolidated Statements of Operations. Benefit Plans Certain employees participate in employee benefit plans, which consist of defined contribution plans including (i) profit-sharing plans qualified under Section 401(k) of the Internal Revenue Code, (ii) a UK pension scheme for U.K. employees and (iii) a Germany pension plan for employees in Germany. Expenses related to the Company’s employee benefit plans was $ 1.2 million and $ 3.8 million for the three and nine months ended September 30, 2021, respectively, and $ 1.1 million and $ 3.5 million for the three and nine months ended September 30, 2020, respectively, and are included in Compensation and benefits in the Condensed Consolidated Statements of Operations. Separation and Termination Benefits In the second quarter of 2020, the Company underwent a review of operations and headcount levels and the decision was made to reduce employee headcount. In conjunction with such reduction, affected employees were offered a combination of separation and transition benefits (the “termination cost”). As of September 30, 2020, the termination cost accrued was approximately $ 5.4 million , which is included in Compensation and benefits in the Condensed Consolidated Statements of Operations. These termination costs were fully recognized once the service requirement of the affected employees was complete. The termination costs were substantially paid by December 31, 2020.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share Attributable to Class A Common Shareholders	Net Income (Loss) Per Share Attributable to Class A Common Shareholders The Company analyzed the calculation of net income (loss) per share for periods prior to the Business Combination on June 24, 2021 and determined that it resulted in values that would not be meaningful to the users of the condensed consolidated financial statements. Therefore, net income (loss) per share information has not been presented for periods prior to the Business Combination. The basic and diluted net income (loss) per share attributable to Class A common shareholders for the nine months ended September 30, 2021, as presented on the Condensed Consolidated Statements of Operations, represent only the period after the Business Combination to September 30, 2021. The calculations of basic and diluted net income (loss) per share attributable to Class A common shareholders are presented below: Three Months Ended September 30, 2021 Period After Business Combination Through September 30, 2021 Numerator: Net income (loss) attributable to Perella Weinberg Partners - basic $ 3,476 $ ( 9,023 ) Dilutive effect from assumed exercise of warrants, net of tax - - Dilutive effect from assumed exchange of PWP OpCo Units, net of tax ( 12,163 ) ( 28,401 ) Dilutive effect from assumed vesting of RSUs and PSUs, net of tax - - Net Income (loss) attributable to Perella Weinberg Partners - diluted $ ( 8,687 ) $ ( 37,424 ) Denominator: Weighted average shares of Class A common stock outstanding - basic 42,572,813 42,599,954 Weighted average number of incremental shares from assumed exercise of warrants - - Weighted average number of incremental shares from assumed exchange of PWP OpCo Units 50,154,199 50,154,199 Weighted average number of incremental shares from assumed vesting of RSUs and PSUs - - Weighted average shares of Class A common stock outstanding - diluted 92,727,012 92,754,153 Net income (loss) per share attributable to Class A common shareholders Basic $ 0.08 $ ( 0.21 ) Diluted $ ( 0.09 ) $ ( 0.40 ) The impact of Class B common stock has been excluded from the calculation as these shares are entitled to an insignificant amount of economic participation. The Company uses the treasury stock method to determine the potential dilutive effect of outstanding warrants and unvested RSUs and PSUs and the if-converted method to determine the potential dilutive effect of exchanges of PWP OpCo Units into Class A common stock. The Company adjusts net income (loss) attributable to Class A common shareholders under both the treasury stock method and if-converted method for the reallocation of net income (loss) between Class A common shareholders and non-controlling interests that result upon the assumed issuance of dilutive shares of Class A common stock as if the issuance occurred as of the Closing Date. The Company also adjusts the net income (loss) attributable to Class A common shareholders under the treasury stock method to reverse the effect on earnings of classifying the warrants as liabilities. All adjustments are net of any tax impact. The following table presents the weighted average potentially dilutive shares that were excluded from the calculation of diluted net income (loss) per share under the treasury stock method or if-converted method, as applicable, because the effect of including such potentially dilutive shares was antidilutive for the periods presented: Three Months Ended September 30, 2021 Period After Business Combination Through September 30, 2021 Warrants 1,075,327 1,075,327 PWP OpCo Units - - RSUs and PSUs 16,112 16,112 1,091,439 1,091,439

Fair Value Measurements and Inv

Fair Value Measurements And Investments [Abstract]
Fair Value Measurements and Investments	Fair Value Measurements and Investments Fair value is generally based on quoted prices, however if quoted market prices are not available, fair value is determined based on other relevant factors, including dealer price quotations, price activity for equivalent instruments and valuation pricing models. The Company established a fair value hierarchy which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a number of factors, including the type of instrument, the characteristics specific to the instrument and the state of the marketplace (including the existence and transparency of transactions between market participants). Financial instruments with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in an orderly market will generally have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed in one of the following categories (from highest to lowest) based on inputs: Level 1 – Unadjusted quoted prices are available in active markets for identical financial instruments as of the reporting date. Level 2 – Pricing inputs are observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. Level 3 – Pricing inputs are unobservable for the financial instruments and includes situations where there is little, if any, market activity for the financial instrument. The inputs into the determination of fair value require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for any given investment is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the instrument. The fair values of cash, restricted cash, accounts receivable, due from related parties, accounts payable and certain accrued liabilities approximate their carrying amounts due to the short-term nature of these items. Due to the variable rate nature of the Revolving Credit Facility, the carrying value as of December 31, 2020 approximated the fair value. Fair Value of Financial Instruments The following table summarizes the categorization and fair value estimate of the Company’s financial instruments that are measured on a recurring basis pursuant to the above fair value hierarchy levels as of September 30, 2021 and December 31, 2020: September 30, 2021 Level 1 Level 2 Level 3 Total Financial assets Investments in mutual funds and other $ 475 $ - $ - $ 475 Cash surrender value of company-owned life insurance - 893 - 893 Total financial assets $ 475 $ 893 $ - $ 1,368 Financial liabilities Warrant liabilities - Public warrants $ 24,226 $ - $ - $ 24,226 Warrant liabilities - Private warrants - - 740 740 Total financial liabilities $ 24,226 $ - $ 740 $ 24,966 December 31, 2020 Level 1 Level 2 Level 3 Total Financial assets Investments in mutual funds and other $ 584 $ - $ - $ 584 Cash surrender value of company-owned life insurance - 857 - 857 Total financial assets $ 584 $ 857 $ - $ 1,441 The Company had no transfers between fair value levels during the three and nine months ended September 30, 2021. As of September 30, 2021 and December 31, 2020, the Company held investments related to a legacy deferred compensation program and securities, which are included in Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. The cash surrender value of company-owned life insurance is included in Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition at the amount that could be realized under the contract as of September 30, 2021 and December 31, 2020, which approximates fair value. The public warrants are valued using quoted market prices on the Nasdaq Capital Market under the ticker PWPPW and are included in Warrant liabilities on the Condensed Consolidated Statements of Financial Condition. As of September 30, 2021, the price per public warrant was $ 3.16 . Management determines the fair value of the private warrants using the Black-Scholes option pricing valuation model (“Valuation Model”). The private warrants are classified as Level 3 as of September 30, 2021 because of the use of significant unobservable inputs in the Valuation Model. The inputs into the Valuation Model for the private warrants, including some significant unobservable inputs, were as follows: September 30, 2021 Risk-free rate of return 0.90 % Expected volatility 27.50 % Expected dividend yield 2.00 % Expected term (years) 5 Exercise price per share $ 11.50 Asset price per share $ 13.28 The Company’s use of the Valuation Model required the use of the following assumptions:  The risk-free rate of return assumption was based on the expected term and a U.S. Treasury yield curve as of the date of the Business Combination. An increase in the risk-free interest rate, in isolation, would result in an increase in the fair value measurement of the warrant liabilities and vice versa.  The expected volatility assumption was based on the weighted average of the implied volatility from the Company’s publicly traded warrants and the historical volatility of the Company’s publicly traded industry peers. An increase in the expected volatility, in isolation, would result in an increase in the fair value measurement of the warrant liabilities.  The dividend yield was based on management ’ s expectation that the Company will pay 2% dividends during the term.

As of September 30, 2021, the Company had an amount due of $ 14.1 million pursuant to the tax receivable agreement, which represents management’s best estimate of the amounts currently expected to be owed in connection with the tax receivable agreement. The Company expects to make the following payments with respect to the tax receivable agreement, which may differ significantly from actual payments made: Years Ending: Estimated Payments Under Tax Receivable Agreement Remainder of 2021 $ - 2022 432 2023 746 2024 757 2025 775 Thereafter 11,398 Total payments $ 14,108 Partner Promissory Notes The Company loaned money pursuant to promissory note agreements (the “Partner Promissory Notes”) to certain partners. The Partner Promissory Notes bear interest at an annual rate equal to the Federal Mid-Term Rate on an annual basis. The Partner Promissory Notes are due on various dates or in the event a partner is terminated or leaves at will. Repayment of the Partner Promissory Notes may be accelerated based on certain conditions as defined in the promissory note agreements and are primarily secured by the partner’s equity interests in the PWP OpCo or other affiliate.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Loan Guarantees The Company has unconditionally guaranteed certain of its partners’ loans with First Republic Bank (“Lender”) whereby it will pay the Lender upon the occurrence of a default event. The total guarantees related to partners was $ 3.5 million and $ 5.6 million as of September 30, 2021 and December 31, 2020, respectively. These guarantees are secured by either the partners’ interests in PWP OpCo or Professional Partners. As of September 30, 2021 and December 31, 2020 , no loan was in default. Indemnifications The Company enters into certain contracts that contain a variety of indemnification provisions. The Company’s maximum exposure under these arrangements is unknown. As of September 30, 2021 and December 31, 2020 , the Company expects no claims or losses pursuant to these contracts; therefore, no liability has been recorded related to these indemnification provisions. Legal Contingencies From time to time, the Company is named as a defendant in legal actions relating to transactions conducted in the ordinary course of business. Some of these matters may involve claims of substantial amounts. Although there can be no assurance of the outcome of such legal actions, in the opinion of management and after consultation with external counsel, the Company believes it is neither probable nor reasonably possible that any current legal proceedings or claims would individually or in the aggregate have a material adverse effect on the condensed consolidated financial statements of the Company as of September 30, 2021 and December 31, 2020 and for the three and nine months ended September 30, 2021 and 2020. On October 20, 2015, Perella Weinberg Partners LLC, PWP MC LP, PWP Equity I LP and Perella Weinberg Partners Group LP (collectively, the “PWP Plaintiffs”), filed a complaint against Michael A. Kramer, Derron S. Slonecker, Joshua S. Scherer, Adam W. Verost (collectively, the “Individual Defendants”) and Ducera Partners LLC (together with the Individual Defendants, the “Defendants”). The complaint alleges that the Individual Defendants, three former partners and one former employee of the PWP Plaintiffs, entered into a scheme while still at PWP to lift out the PWP Plaintiffs’ restructuring group to form a new competing firm that they were secretly forming in breach of their contractual and fiduciary duties to the PWP Plaintiffs. The complaint contains fourteen causes of action, and seeks declaratory relief as well as damages resulting from the Individual Defendants’ breaches of their obligations under the PWP Plaintiffs’ partnership and employment agreements, and from Defendants’ unfair competition and tortious interference with the PWP Plaintiffs’ contracts and client relationships. On November 9, 2015, the Defendants filed an Answer, Counterclaims, Cross-claims and a Third-Party Complaint, which contained 14 causes of action. On July 17, 2016, the Court issued a decision, dismissing half of the Defendants’ counterclaims and cross-claims with prejudice. On August 18, 2016, the Defendants filed an Amended Answer, Counterclaims, Cross-claims and Third-Party Complaint, which contained only seven counterclaims and cross-claims. On December 12, 2016, the Defendants appealed the dismissal of three of their counterclaims and cross-claims to the New York Appellate Division, First Department (the “First Department”). On August 29, 2017, the First Department issued a decision denying the Defendants’ appeal in its entirety other than allowing only one Defendant to proceed with his breach of fiduciary duty counterclaim. On October 27, 2017, the Defendants moved the First Department for leave to appeal its decision to the New York Court of Appeals. On December 28, 2017, the First Department denied the Defendants’ motion for leave to appeal to the New York Court of Appeals. On April 24, 2018, the Defendants filed a Second Amended Answer, Counterclaims, Cross-claims and Third-Party Complaint, which contains eight counterclaims and cross-claims. The Defendants are seeking declaratory relief and damages of no less than $ 60.0 million, as well as statutory interest. Discovery is complete. Both the PWP Plaintiffs and the Defendants subsequently moved for summary judgment. As of March 20, 2020, the parties had completed briefing their respective motions for summary judgment. The PWP Plaintiffs moved affirmatively for summary judgment on each of their 14 claims and also moved for dismissal of each of the Defendants’ remaining eight counterclaims and cross-claims. The Defendants moved affirmatively for summary judgment on four of their eight counterclaims and cross-claims and also moved for dismissal of each of the PWP Plaintiffs’ 14 claims. The Court held oral argument on the motions for summary judgment on May 27, 2021. The Court has yet to issue a decision on the motions for summary judgement. We believe that our 14 causes of action are meritorious. Further, we believe that we have substantial meritorious defenses to the Defendants’ remaining counterclaims and cross-claims and plan to vigorously contest them. Litigation, however, can be uncertain and there can be no assurance that any judgment for one or more of the Defendants or other outcome of the case would not have a material adverse effect on us. Additionally, even if we prevail in the litigation and are awarded damages, we do not know if we will be able to fully collect on any judgment against any or all Defendants. The Company incurred $ 0.9 million during both the three and nine months ended September 30, 2021, and $ 0.4 million and $ 1.1 million during the three and nine months ended September 30, 2020, respectively, in legal and professional fees, net of expected insurance reimbursement, related to this litigation. These litigation costs are included in Professional fees in the Condensed Consolidated Statements of Operations. Other In the ordinary course of business and in connection with hiring certain senior employees, the Company entered into employment agreements whereby the Company committed to grant equity awards to such newly hired employees contingent upon certain events (including but not limited to the Company becoming a public company). The Company settled these commitments in the third quarter of 2021 with a grant of awards approved by the compensation committee under our PWP Incentive Plan.

Segment Reporting [Abstract]
Business Information	Business Information The Company’s activities of providing advisory services for mergers-and-acquisitions, private placements and financial advisory, as well as services for underwriting of securities offered for sale in public markets, commissions for the brokerage of publicly traded securities and equity research constitute a single business segment. The Company is organized as one operating segment in order to maximize the value of advice to clients by drawing upon the diversified expertise and broad relationships of its senior professionals across the Company. The Company has a single operating segment and therefore a single reportable segment. For the three months ended September 30, 2021, revenues of $ 54.1 million related to two individual clients accounted for more than 10% of aggregate revenue. For the nine months ended September 30, 2021, no individual client accounted for more than 10% of aggregate revenue. For the three months ended September 30, 2020, revenues of $ 17.9 million related to one individual client accounted for more than 10% of aggregate revenue. For the nine months ended September 30, 2020, no individual client accounted for more than 10% of aggregate revenue. Since the financial markets are global in nature, the Company generally manages its business based on the operating results of the Company taken as a whole, not by geographic region. The following tables set forth the geographical distribution of revenues and assets based on the location of the office that generates the revenues or holds the assets and therefore may not be indicative of the geography in which the Company’s clients are located: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Revenues United States $ 150,113 $ 96,519 $ 494,976 $ 237,869 International 27,314 26,325 107,773 91,972 Total $ 177,427 $ 122,844 $ 602,749 $ 329,841 September 30, 2021 December 31, 2020 Assets United States $ 496,273 $ 406,884 International 167,387 136,069 Total $ 663,660 $ 542,953

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements reflect the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The Business Combination was treated as a reverse recapitalization transaction between entities under common control, whereby PWP OpCo was considered the accounting acquirer and predecessor entity and therefore recognized the carrying value of the net assets of FTIV as an equity contribution with no incremental goodwill or intangible assets. The historical operations of PWP OpCo are deemed to be those of the Company. Thus, the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect (i) the historical operating results of PWP OpCo prior to the Business Combination and (ii) the combined results of the Company following the Business Combination. See Note 3 – Business Combination for additional discussion related to the transaction. These condensed consolidated financial statements and notes thereto are unaudited, and as permitted by the interim reporting rules and regulations set forth by the Securities and Exchange Commission (the “SEC”), exclude certain financial information and note disclosures normally included in annual audited financial statements prepared in accordance with U.S. GAAP. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s definitive proxy statement, dated May 27, 2021 (as amended or supplemented, including the filing of definitive additional materials, the “Proxy Statement”). The condensed consolidated financial statements reflect all material adjustments of a normal recurring nature that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods. All intercompany balances and transactions between the consolidated subsidiaries comprising the Company have been eliminated in the accompanying condensed consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements and related disclosures in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and the assumptions underlying these estimates are reviewed periodically, and the effects of revisions are reflected in the period in which they are determined to be necessary. In preparing the condensed consolidated financial statements, management makes estimates regarding the following:  adequacy of the allowance for credit losses;  measurement and realization of deferred taxes;  measurement of equity-based awards;  evaluation of goodwill and intangible assets;  fair value measurement of financial instruments; and  other matters that affect the reported amounts and disclosures of contingencies in the condensed consolidated financial statements.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents includes cash and highly liquid investments with original maturities of three months or less from the date of purchase. As of September 30, 2021 and December 31, 2020 , the Company had no cash equivalents. The Company maintains cash with banks and brokerage firms, which from time to time may exceed federally insured limits. Restricted cash represents cash that is not readily available for general purpose cash needs. As of both September 30, 2021 and December 31, 2020, the Company had restricted cash of $ 1.8 million maintained as collateral for letters of credit related to the Company’s New York City and Paris office leases. A reconciliation of the Company’s cash, cash equivalents and restricted cash as of September 30, 2021 and September 30, 2020 is presented below: September 30, 2021 2020 Cash $ 415,839 $ 186,225 Cash equivalents - - Restricted cash 1,835 1,835 Cash, cash equivalents and restricted cash as shown on statements of cash flows $ 417,674 $ 188,060
Accounts Receivable	Accounts Receivable Accounts receivable are presented net of allowance for credit losses based on the Company’s assessment of collectability. The Company regularly reviews its accounts receivable for collectability and an allowance is recognized for credit losses, if required. As of September 30, 2021 and December 31, 2020, $ 47.9 million and $ 5.1 million , respectively, of accrued revenue was included in Accounts receivable, net of allowance on the Condensed Consolidated Statements of Financial Condition. Accrued revenue represents amounts due from clients and recognized as revenue in accordance with the Company’s revenue recognition policies but unbilled as of September 30, 2021 and December 31, 2020. Accounts receivable represents amounts due from clients from various industry and geographic backgrounds. As of September 30, 2021, certain accounts receivable in the aggregate amount of $ 26.5 million were individually greater than 10% of the Company’s total accounts receivable and were concentrated with one client. Of that amount, all was subsequently received after September 30, 2021. As of December 31, 2020 , there were no accounts receivable individually greater than 10% of the Company’s total accounts receivable.
Allowance for Credit Losses	Allowance for Credit Losses On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), under the modified retrospective approach. This new standard replaces the incurred loss impairment methodology for financial instruments with the current expected credit loss (“CECL”) model which requires an estimate of future credit losses. The Company maintains an allowance for credit losses that, in management’s opinion, provides for an adequate reserve to cover estimated losses on accounts receivable. The Company determines the adequacy of the allowance by estimating the probability of loss based on the Company’s historical credit loss experience of its client receivables and taking into consideration current market conditions and supportable forecasts that affect the collectability of the reported amount. The Company updates its average credit loss rates periodically and maintains a quarterly allowance review process to consider current factors that would require an adjustment to the credit loss allowance. In addition, the Company periodically performs a qualitative assessment to monitor risks associated with current and forecasted conditions that may require an adjustment to the expected credit loss rates. The Company also regularly reviews the age of the receivables, credit worthiness of the client and the current economic conditions that may affect a client’s ability to pay such amounts owed to the Company and as a result, may recognize a specific credit loss reserve. Changes to expected credit losses during the period are included in General, administrative and other expenses in the Condensed Consolidated Statements of Operations. After concluding that a reserved accounts receivable is no longer collectible, the Company reduces both the gross receivable and the allowance for credit losses
Consolidation	Consolidation The Company’s policy is to consolidate entities in which the Company has a controlling financial interest and variable interest entities where the Company is deemed to be the primary beneficiary. The Company is deemed to be the primary beneficiary of a variable interest entity (“VIE”) when it has both (i) the power to make the decisions that most significantly affect the economic performance of the VIE and (ii) the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. PWP is the primary beneficiary of and consolidates PWP OpCo, a VIE. The assets and liabilities of PWP OpCo represent substantially all of the Company's consolidated assets and liabilities with the exception of certain cash, income taxes payable, and deferred tax balances as well as all amounts due pursuant to the tax receivable agreement. As of September 30, 2021 and December 31, 2020, the net assets of PWP OpCo were $ 259.9 million and $ 74.2 million , respectively. As of September 30, 2021 and December 31, 2020 , the Company did not consolidate any VIEs other than PWP OpCo that were deemed material to the condensed consolidated financial statements.
Equity Method Investments	Equity Method Investments When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity’s operating and financial decisions, the Company applies the equity method of accounting. The investment balance related to an equity method investee reflects the Company’s share of contributions made to, distributions received from, and the equity earnings and losses of the investee. Equity method investments are included within Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition. The Company reflects its share of income and losses of the investee in Other income (expense) on the Condensed Consolidated Statements of Operations using the most recently available earnings data for the reporting period.
Prepaid Expenses and Other Assets	Prepaid Expenses and Other Assets The majority of Prepaid expenses and other assets consists of prepaid expenses, and from time to time, deferred offering costs and receivables from carrying brokers for unsettled trades as noted below. Prepaid expenses relate to various services, including subscriptions, software licenses and insurance, which are amortized over the life, related service period or policy. Deferred offering costs are associated with the reorganization and recapitalization efforts related to the pursuit of becoming a publicly traded company. The Company initially pursued a traditional initial public offering but later terminated this process in May 2020. Upon termination, the Company expensed all previously deferred offering costs totaling $ 14.8 million to Professional fees on the Condensed Consolidated Statements of Operations. Later in 2020, the Company reinitiated efforts of becoming a publicly traded company via the Business Combination and deferred certain offering costs until the Closing Date. These costs were netted against proceeds of the Business Combination on the Closing Date, and as such, no deferred offering costs are included within Prepaid expenses and other assets on the Condensed Consolidated Statements of Financial Condition as of September 30, 2021. As of December 31, 2020, cumulative offering costs of $ 9.1 million were deferred within Prepaid expenses and other assets. Tudor, Pickering, Holt & Co. Securities Canada, ULC (“TPH Canada”) executes certain client trades through a counterparty other than its carrying broker (referred to as “broker-to-broker trades”). Per the introducing broker agreement between TPH Canada and its carrying broker, TPH Canada assumes the risk of any failed obligations with respect to broker-to-broker trades and is required to reimburse the carrying broker for any loss which the carrying broker may sustain as a result of these trades. TPH Canada is deemed to be a principal with regards to broker-to-broker trades; and therefore, the value of unsettled broker-to-broker trades as of September 30, 2021 and December 31, 2020 in the amount of $ 12.8 million and $ 0.1 million , respectively, was recorded as a receivable from the carrying broker or other counterparty as well as a corresponding payable to the carrying broker or other counterparty, which were included in Prepaid expenses and other assets and Accounts payable, accrued expenses and other liabilities, respectively, on the Condensed Consolidated Statements of Financial Condition. Subsequent to September 30, 2021 , these trades were settled and the related receivable and payable were derecognized.
Warrants	Warrants The Company evaluated the public and private warrants under Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, and concluded that they do not meet the criteria to be classified as equity in the Condensed Consolidated Statements of Financial Condition. Since the public and private warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities at fair value upon the closing of the Business Combination in accordance with ASC 820, Fair Value Measurement , with subsequent changes in their respective fair values recorded in Change in fair value of warrant liabilities on the Condensed Consolidated Statements of Operations and on the Condensed Consolidated Statements of Cash Flows.
Tax Receivable Agreement	Tax Receivable Agreement In connection with the Business Combination as described in Note 3 – Business Combination, PWP entered into a tax receivable agreement with PWP OpCo, Professional Partners and ILPs under which PWP agreed to payment of 85 % of the amount of savings, if any, that PWP realizes in U.S. federal, state, local and foreign income taxes as a result of (i) exchanges of interests in PWP OpCo for cash or stock of the Company and certain other transactions and (ii) payments made under the tax receivable agreement. Management’s best estimate of the amounts expected to be owed in connection with the tax receivable agreement at each reporting date are reported within the Amount due pursuant to tax receivable agreement on the Condensed Consolidated Statements of Financial Condition.
Income Taxes	Income Taxes Prior to the Business Combination, the Company operated as a partnership, and therefore, was generally not subject to U.S. federal and state corporate income taxes. Subsequent to the Business Combination, PWP is a corporation and is subject to U.S. federal and state corporate income taxes on its proportionate share of taxable income generated by the operating partnership, PWP OpCo, as well as any standalone income (or loss) generated at the PWP entity level. PWP OpCo is treated as a partnership, and as a result, taxable income (or loss) generated by PWP OpCo flows through to its limited partners, including PWP, and is generally not subject to U.S. federal or state income tax at the partnership level. The Company primarily conducts business through disregarded entities held by PWP OpCo, as well as non-U.S. subsidiaries which generally operate as corporate entities in various non-U.S. jurisdictions. Certain non-U.S. subsidiaries are subject to income taxes in their respective local jurisdictions, and therefore, the related income tax provision is reported in the Condensed Consolidated Statements of Operations. Taxes are accounted for using the asset and liability method of accounting pursuant to ASC 740, Income Taxes (“ASC 740”). Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases, using tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent on the amount, timing and character of the Company’s future taxable income. When evaluating the realizability of deferred tax assets, all evidence – both positive and negative – is considered. This evidence includes, but is not limited to, expectations regarding future earnings, future reversals of existing temporary tax differences and tax planning strategies. The Company analyzes its tax positions for all U.S. federal, state and local tax jurisdictions where it is required to file income tax returns in accordance with the provisions of ASC 740. This standard establishes consistent thresholds for recognizing the benefits of tax return positions in the financial statements as more-likely-than-not to be sustained by the relevant taxing authority upon audit. This standard requires a two-step process in which (i) determination is made whether it is more-likely-than-not that the tax position will be sustained based on the technical merits of the position, and (ii) those tax positions that meet the more-likely-than-not threshold are recognized as the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. If upon performance of an assessment pursuant to ASC 740 the Company determines that uncertainties in tax positions exist that do not meet the minimum threshold for recognition of the related tax benefit, a liability is recorded in the condensed consolidated financial statements. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits as Interest expense and General, administrative and other expenses in the Condensed Consolidated Statements of Operations.
Equity-Based Compensation	Equity-Based Compensation Equity-based compensation relates to equity-based awards granted to employees and partners of the Company. In all instances of equity-based awards, compensation expense is recognized over the requisite vesting period in an amount equal to the fair value of the awards at the grant date. Equity-based compensation expense for employees and partners are included in Compensation and benefits on the Condensed Consolidated Statements of Operations and equity-based compensation expense for non-employees is included in Professional fees on the Condensed Consolidated Statements of Operations. Refer to Note 13 – Equity-Based Compensation for detail of amounts included in each financial statement line item. The Company accounts for forfeitures of awards as they occur rather than applying an estimated forfeiture rate. For an award with service-only conditions that has a graded vesting schedule, the Company recognizes the compensation cost for the entire award on a straight-line basis over the requisite service period, ensuring that the amount recognized is at least equal to the vested portion of the award at each reporting date.
Non-Controlling Interests	Non-Controlling Interests For entities that are consolidated but not 100% owned, a portion of the income or loss and equity is allocated to holders of the non-controlling interest. The aggregate of the income or loss and corresponding equity that is owned by the holders of the non-controlling interest is included in non-controlling interest in the condensed consolidated financial statements. Non-controlling interests are presented as a separate component of equity on the Condensed Consolidated Statements of Financial Condition. Net income (loss) includes the net income (loss) attributable to the holders of the non-controlling interests on the Condensed Consolidated Statements of Operations. Profits and losses of PWP OpCo are allocated to the non-controlling interests in proportion to their ownership interest regardless of their basis, with an exception for certain equity-based compensation expense which are fully attributed to non-controlling interests.

Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per share is calculated by dividing net income (loss) attributable to Class A common shareholders by the weighted-average shares of Class A common shares outstanding without the consideration for potential dilutive securities. Diluted net income (loss) per share represents basic net income (loss) per share adjusted to include the potentially dilutive effect of outstanding unvested share awards, warrants, and PWP OpCo Units that are exchangeable into shares of Class A common stock on a one-for-one basis. Diluted net income (loss) per share is computed by dividing the net income attributable to Class A common shareholders by the weighted-average number of shares of Class A common stock outstanding for the period determined using the treasury stock method and if-converted method, as applicable.
