Forward-Looking Statements

Certain material presented herein contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include certain information concerning future results of operations, business strategies, acquisitions, financing plans, competitive position, potential growth opportunities, potential operating performance improvements, the effects of competition and the effects of future legislation or regulations. Forward-looking statements include all statements that are not historical facts and can be identified by the use of forward-looking terminology such as the words “believe,” “expect,” “opportunity,” “plan,” “intend,” “anticipate,” “estimate,” “predict,” “potential,” “continue,” “may,” “might,” “should,” “could” or the negative of these terms or similar expressions.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company’s current beliefs, expectations, and assumptions regarding the future of its business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict, many of which are outside the Company’s control. The Company’s actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not place undue reliance upon any of these forward-looking statements. Important factors that could cause the Company’s actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: (a) changes in governmental regulations and policies; (b) the possibility of cyberattacks, security vulnerabilities, and internet disruptions, including breaches of data security and privacy leaks, data loss, and business interruptions; (c) the possibility of failure of the Company’s computer systems or communication systems during a catastrophic event, including as a result of the increased use of remote work environments and virtual platforms during the outbreak of COVID-19 (coronavirus); (d) the impact of catastrophic events, such as COVID-19, on the U.S. and the global economy, including business disruptions, reductions in employment and an increase in business failures; (e) the impact of catastrophic events, such as COVID-19, on the Company’s employees and the Company’s ability to provide services to its clients and respond to their needs; (f) the failure of third-party service providers to perform their functions; and (g) volatility in the political and economic environment.

Any of these factors, as well as such other factors discussed in the “Risk Factors” section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 and Quarterly Report on Form 10-Q for the three months ended June 30, 2020, in each case filed with the United States Securities and Exchange Commission (“SEC”), as such factors may be updated from time to time in the Company’s periodic filings with the SEC, accessible on the SEC’s website at www.sec.gov, could cause the Company’s results to differ materially from those expressed in forward-looking statements. There may be other risks and uncertainties that the Company is unable to predict at this time or that are not currently expected to have a material adverse effect on its business. Any such risks could cause the Company’s results to differ materially from those expressed in forward-looking statements.

Non-GAAP Financial Measures

The following represent key performance measures that management uses in making resource allocation and/or compensation decisions. These measures should not be considered substitutes for, or superior to, financial measures prepared in accordance with GAAP.

Management believes the following non-GAAP measures, when presented together with comparable GAAP measures, are useful to investors in understanding the Company’s operating results: Adjusted Pretax Income; Adjusted Net Income; Adjusted Net Income, If-Converted, in total and on a per-share basis (referred to as “Adjusted EPS”); Adjusted Compensation and Benefits Expense and Adjusted Non-Compensation Expense. These non-GAAP measures, presented and discussed in this earnings release, remove the significant accounting impact of: (a) transaction-related compensation expense, including expense related to Partnership Units with both time-based vesting and market conditions as well as equity-based and cash awards granted in connection with the spin-off from Blackstone and acquisition of CamberView Partners Holdings, LLC (“CamberView”); (b) intangible asset amortization associated with Blackstone’s initial public offering (“IPO”), the acquisition of PJT Capital LP, and the acquisition of CamberView; and (c) the amount the Company has agreed to pay Blackstone related to the net realized cash benefit from certain compensation-related tax deductions. Reconciliations of the non-GAAP measures to their most directly comparable GAAP measures and further detail regarding the adjustments are provided in the Appendix.

To help investors understand the effect of the Company’s ownership structure on its Adjusted Net Income, the Company has presented Adjusted Net Income, If-Converted. This measure illustrates the impact of taxes on Adjusted Pretax Income, assuming all Partnership Units (excluding the unvested partnership units that have yet to satisfy certain market conditions) were exchanged for shares of the Company’s Class A common stock, resulting in all of the Company’s income becoming subject to corporate-level tax, considering both current and deferred income tax effects. This tax rate excludes the tax benefits of the adjustments for transaction-related compensation expense, amortization expense, tax benefit recorded pursuant to the CARES Act as well as certain payments to Blackstone resulting from the October 1, 2015 spin-off.
