Compensation and Benefits Expense

Year Ended December 31, 2016 vs. 2015

GAAP Compensation and Benefits Expense was $381.0 million for the year ended December 31, 2016 compared with $315.2 million for the year ended December 31, 2015. Adjusted Compensation and Benefits Expense was $315.2 million for the year ended December 31, 2016 compared with $278.3 million for the year ended December 31, 2015. The increase in GAAP Compensation and Benefits Expense was primarily due to a full year of amortization of equity compensation related to our spin-off from Blackstone on October 1, 2015 (the “spin-off”), as well as an increase in headcount and improved business performance.

Three Months Ended December 31, 2016 vs. 2015

GAAP Compensation and Benefits Expense was $125.0 million for the three months ended December 31, 2016 compared with $108.4 million for the three months ended December 31, 2015. Adjusted Compensation and Benefits Expense was $107.5 million for the three months ended December 31, 2016 compared with $93.4 million for the three months ended December 31, 2015. The increase in GAAP Compensation and Benefits Expense was primarily due to increases in amortization of equity compensation related to the spin-off and increased headcount, as well as improved business performance.

Non-Compensation Expense

Year Ended December 31, 2016 vs. 2015

GAAP Non-Compensation Expense was $103.9 million for the year ended December 31, 2016 compared with $96.7 million for the year ended December 31, 2015. Adjusted Non-Compensation Expense was $91.0 million for the year ended December 31, 2016 compared with $85.7 million for the year ended December 31, 2015.

The increase in Non-Compensation Expense was primarily due to an increase in other expenses consisting of the previously disclosed $3.3 million charge (including an offset for insurance recovery) recorded in the first quarter of 2016, certain spin-off-related payables due to Blackstone, an increase in bad debt expense and increased costs associated with the Company’s operation as a stand-alone public company since October 1, 2015. These increases were partially offset by a decrease in occupancy and related expense reflecting 2015 rent expense for both current and previous office locations during the period of transition.

Three Months Ended December 31, 2016 vs. 2015

GAAP Non-Compensation Expense was $24.5 million for the three months ended December 31, 2016 compared with $24.1 million for the three months ended December 31, 2015. Adjusted Non-Compensation Expense was $23.1 million for the three months ended December 31, 2016 compared with $21.1 million for the three months ended December 31, 2015.

Non-Compensation Expense increased slightly during the three months ended December 31, 2016 compared with the three months ended December 31, 2015. The increase in other expenses was primarily due to the recording of bad debt expense of $1.7 million in the fourth quarter of 2016 compared with recording the recovery of bad debt of $1.5 million in the fourth quarter of 2015.

Provision for Taxes

Prior to October 1, 2015, the Company’s operations were included in Blackstone subsidiaries’ U.S. federal, state and foreign tax returns. As a stand-alone entity, the Company’s deferred taxes and effective tax rate differ from those in historical periods.

As of December 31, 2016, PJT Partners Inc. owned 53.4% of PJT Partners Holdings LP and was subject to corporate U.S. federal and state income tax. PJT Partners Holdings LP continues to be subject to New York City unincorporated business tax and other entity-level taxes imposed by certain state and foreign jurisdictions. Refer to Note 3. “Reorganization and Spin-off” in the “Notes to Consolidated and Combined Financial Statements” in “Part II. Item 8. Financial Statements and Supplementary Data” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 for further information about the corporate ownership structure.

In calculating Adjusted Net Income, If-Converted, the Company has assumed that all outstanding Class A partnership units in PJT Partners Holdings LP (“Partnership Units”) (excluding the unvested partnership units that have yet to satisfy certain market conditions) have been exchanged into Class A common stock, subjecting all of the Company’s income to corporate-level tax. This presentation is provided for periods beginning in 2016.

The effective tax rates for Adjusted Net Income, If-Converted for the three months and year ended December 31, 2016 were 38.0% and 38.3%, respectively, and include the tax impacts of the adjustments for transaction-related equity-based compensation expense, amortization expense and spin-off-related payables due to Blackstone along with the associated tax deductions.

Capital Management and Balance Sheet

As of December 31, 2016, the Company held cash and cash equivalents of $152.4 million and there was no funded debt.

Beginning in the third quarter of 2016 and each subsequent quarter, Partnership Units presented to the Company for exchange may be repurchased for cash or, at the Company’s election, for shares of the Company’s Class A common stock on a one-for-one basis. With respect to the third quarter exchange, the Company settled 594,072 Partnership Units for cash in the amount of $16.1 million. During the fourth quarter, the Company was presented with 361,588 Partnership Units to be exchanged. The Company has determined that it will also settle this exchange using cash on hand. The price per Partnership Unit to be paid by the Company will be determined by the volume-weighted average price of a share of the Company’s Class A common stock on February 13, 2017.

The Board of Directors of PJT Partners Inc. has declared a quarterly dividend of $0.05 per share of Class A common stock. The dividend will be paid on March 23, 2017 to Class A common stockholders of record on March 9, 2017.

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 (Loss); Adjusted Net Income (Loss); Adjusted Net Income, If-Converted, in total and on a per-share basis; 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 equity-based compensation expense, including expense related to Partnership Units with both time-based vesting and market conditions as well as equity-based retention awards granted in connection with the spin-off; (b) severance incurred in connection with the spin-off (for periods through the third quarter of 2015); (c) intangible asset amortization associated with Blackstone’s initial public offering (“IPO”) and the acquisition of PJT Capital LP; and (d) 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.

In the interest of limiting the adjustments to GAAP results reflected in Adjusted Net Income (Loss) to only the most significant items, the Company amended its definition of Adjusted Net Income (Loss) in the third quarter of 2015 to no longer exclude certain transaction-related non-compensation expenses associated with the spin-off. Adjusted Net Income (Loss) amounts presented for prior periods have been conformed to this presentation.

Additionally, in the second quarter of 2016, the Company amended its definition of tax expense used to compute Adjusted Net Income (Loss) to reflect the manner in which taxes are computed under GAAP. Adjusted Taxes previously represented the total GAAP tax provision adjusted to include only current income taxes. Adjusted Taxes presented for prior periods in this earnings release have been conformed to this presentation.

To help investors understand the effect of the Company’s ownership structure on its Adjusted Net Income (Loss), the Company is presenting Adjusted Net Income, If-Converted, for periods beginning in 2016. This measure illustrates the impact on adjusted earnings if all partnership units in PJT Partners Holdings LP (excluding the unvested partnership units that have yet to satisfy certain market conditions) were to be exchanged for shares of Class A common stock, resulting in all of the Company’s income becoming subject to corporate-level tax on the basis of the method 2016 taxes are calculated.
