Expenses

The following table sets forth information relating to the Company’s expenses (dollars in thousands; unaudited):

Compensation and Benefits Expense

GAAP Compensation and Benefits Expense was $72.0 million for the three months ended June 30, 2016 compared with $60.1 million for the three months ended June 30, 2015. Adjusted Compensation and Benefits Expense was $56.0 million for the three months ended June 30, 2016 compared with $48.7 million for the three months ended June 30, 2015. The increase in Compensation and Benefits Expense was primarily due to an increase in revenues compared with the three months ended June 30, 2015.

GAAP Compensation and Benefits Expense was $160.1 million for the six months ended June 30, 2016 compared with $139.8 million for the six months ended June 30, 2015. Adjusted Compensation and Benefits Expense was $128.8 million for the six months ended June 30, 2016 compared with $116.4 million for the six months ended June 30, 2015. The increase in Compensation and Benefits Expense was primarily due to an increase in revenues compared with the six months ended June 30, 2015.

Non-Compensation Expense

GAAP Non-Compensation Expense was $27.6 million for the three months ended June 30, 2016 compared with $18.8 million for the three months ended June 30, 2015. Adjusted Non-Compensation Expense was $24.8 million for the three months ended June 30, 2016 compared with $18.1 million for the three months ended June 30, 2015.

The increase in Non-Compensation Expense was primarily due to increases in professional fees, including fees incurred related to the Caspersen matter, as well as communications and information services and other expenses. The primary reason for the increase in other expenses was due to an increase in bad debt expense in the second quarter of 2016 while the second quarter of 2015 included bad debt recovery. The increases in other expenses and communications and information services also reflect increased costs associated with the Company’s operation as a stand-alone public company since October 1, 2015. Non-Compensation Expense was partially offset by a reduction in occupancy and related expense, as the three months ended June 30, 2015 reflected rent expense for both current and previous office locations during the period of transition.

GAAP Non-Compensation Expense was $52.0 million for the six months ended June 30, 2016 compared with $36.2 million for the six months ended June 30, 2015. Adjusted Non-Compensation Expense was $46.4 million for the six months ended June 30, 2016 compared with $34.8 million for the six months ended June 30, 2015.

The increase in Non-Compensation Expense was primarily due to the previously disclosed $3.3 million charge (including an offset for insurance recovery deemed to be probable of receipt) recorded in the first quarter of 2016

and increased professional fees related to the Caspersen matter in the second quarter. In addition, other expenses increased due to an increase in bad debt expense in the second quarter of 2016 while the second quarter of 2015 included bad debt recovery. The Company also incurred additional costs associated with the Company’s operation as a stand-alone public company since October 1, 2015.

GAAP Non-Compensation Expense for the three and six months ended June 30, 2016 also reflects additional amortization expense related to intangible assets identified in connection with the acquisition of PJT Capital LP on October 1, 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 may differ from those in historical periods.

As of June 30, 2016, PJT Partners Inc. owns 52.8% of PJT Partners Holdings LP and is 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.

The GAAP Benefit for Taxes was $5.5 million for the three months ended June 30, 2016 compared with a Provision for Taxes of $0.6 million for the three months ended June 30, 2015. The effective tax rate for the three months ended June 30, 2016 was 54.0% compared with -9.1% for the three months ended June 30, 2015. The effective tax rate increased primarily due to federal and state income tax expense accrued for the Company as a publicly traded corporation (effective October 1, 2015).

The GAAP Benefit for Taxes was $4.2 million for the six months ended June 30, 2016 compared with a Provision for Taxes of $2.0 million for the six months ended June 30, 2015. The effective tax rate for the six months ended June 30, 2016 was 56.3% compared with -9.5% for the six months ended June 30, 2015. The effective tax rate increased primarily due to federal and state income tax expense accrued for the Company as a publicly traded corporation (effective October 1, 2015).

Additionally, the magnitude of equity-based compensation expense not deductible for income tax purposes relative to the projected pretax income gives rise to a higher GAAP effective tax rate.

In calculating Adjusted Net Income, If-Converted, the Company has assumed that all outstanding Class A partnership units of PJT Partners Holdings LP (excluding the unvested partnership units that have yet to satisfy 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 after October 1, 2015, the date of the spin-off.

The effective tax rates for Adjusted Net Income, If-Converted for the three and six months ended June 30, 2016 were 38.6% and 38.7%, respectively, and include the tax impacts of the adjustments for transaction-related equity-based compensation and amortization expense.

Capital Management and Balance Sheet

As of June 30, 2016, the Company held cash and cash equivalents of $103.2 million and there was no debt on the balance sheet.

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 September 21, 2016 to Class A common stockholders of record on September 7, 2016.

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; 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

5

the spin-off (for periods through the third quarter of 2015), and (c) intangible asset amortization associated with Blackstone’s initial public offering (“IPO”) and the acquisition of PJT Capital LP. 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 to only the most significant items, the Company amended its definition of Adjusted Net Income in the third quarter of 2015 to no longer exclude certain transaction-related non-compensation expenses associated with the spin-off. Adjusted Net Income 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 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, the Company is presenting Adjusted Net Income, If-Converted, for periods beginning after the spin-off on October 1, 2015. This measure illustrates the impact on adjusted earnings if all Class A partnership units of PJT Partners Holdings LP (excluding the unvested partnership units that have yet to satisfy 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.
