Korn Ferry International Announces Fourth Quarter and Fiscal 2016 Results of Operations

Highlights

Los Angeles, CA, June 15, 2016 – Korn/Ferry International (NYSE: KFY), the preeminent global people and organizational advisory firm, today announced record fourth quarter and annual fee revenue of $399.9 million and $1.3 billion, or $405.0 million and $1.3 billion on an adjusted basis, respectively. Fourth quarter diluted earnings per share and adjusted diluted earnings per share were $0.10 and $0.58, respectively. FY’16 diluted earnings per share were $0.58 and adjusted diluted earnings per share were $2.08. The adjusted diluted earnings per share for the fourth quarter and the full year excluded $32.9 million and $103.9 million, respectively, of restructuring charges, net, integration/acquisition and separation costs, a deferred revenue adjustment related to the Hay Group acquisition (which also impacted adjusted fee revenue) and a non-cash loss relating to the Venezuelan currency devaluation.

“Korn Ferry closed strong in the final quarter of its fiscal year with fee revenue of $399.9 million representing 47% growth, or adjusted fee revenue of $405.0 million representing 49% growth, and diluted earnings per share of $0.10, or adjusted diluted earnings per share of $0.58,” said Gary D. Burnison, CEO Korn Ferry. “I am enormously proud of our company and the results we have achieved during the quarter, and at the same time, continuing to deliver on the Hay Group integration at a scope and pace that has exceeded our initial expectations.

“We are in the midst of creating a new firm – with 65% of our colleagues new to the organization in the last three years, due to expansion and growth. We are a company that accelerates our clients’ business performance through solutions and productized services that span from strategy implementation and organizational design to recruitment and leadership development to compensation and reward strategies. Our advisory business, now bolstered by our Hay Group combination, has given us more reasons to engage with clients. Also, our recruiting businesses, Executive Search and Futurestep, have never been stronger than they were in the fourth quarter. We are indeed creating the preeminent organizational and people advisory firm,” Burnison added.

Hay Group Integration

In the fourth quarter of FY’16, we continued to make significant progress on the Hay Group integration. The majority of our fourth quarter efforts were focused on activities associated with integration of our go-to-market activities, our intellectual property and content, our solution sets and service offerings, and our back office systems and business processes. We incurred a minimal amount of restructuring costs, including real estate co-location. The fourth quarter results benefitted from the third quarter restructuring and integration actions with the new Hay Group segment EBITDA margin coming in at 5.6%, or 15.9% on an adjusted basis.

As previously disclosed, the integration of Hay Group will be substantially complete in Q1 FY’17, which will include additional consolidation of office space and the elimination of other redundant operational and general and administrative expenses. We estimate the cost of these actions to be in the range of $20 million to $26 million, resulting in incremental annualized savings of approximately $17 million to $23 million.

Selected Financial Results

(dollars in millions, except per share amounts)

Fiscal 2016 Fourth Quarter Results

Fee revenue was $399.9 million in Q4 FY’16 and adjusted fee revenue was $405.0 million (including $5.1 million in deferred revenue adjustment related to the Hay Group acquisition).

Operating margin was 1.2% in Q4 FY’16 compared to 10.3% in the year-ago quarter. The decrease in operating margin was due to an increase in integration/acquisition costs as well as restructuring charges, net, a foreign currency loss relating to the devaluation of the Venezuelan currency and the deferred revenue adjustment referenced above.

EBITDA margin was 5.4% and Adjusted EBITDA margin was 13.4%. The year-over-year decline in Adjusted EBITDA margin (160 bps) was primarily due to an increase in compensation and benefits expense in the Futurestep segment and North America region of Executive Search to support the growth in revenue and an increased bonus expense associated with better than budgeted performance.

Fiscal 2016 Results

Fee revenue was $1,292.1 million in FY’16 and adjusted fee revenue was $1,303.1 million (including $11.0 million in deferred revenue adjustment related to the Hay Group acquisition).

Operating income was $52.7 million in FY’16, resulting in an operating margin of 4.1% in FY’16 compared to 11.1% in FY’15. The decrease in operating income and margin was due to an increase in integration/acquisition and restructuring costs as well as a foreign currency loss relating to the devaluation of the Venezuelan currency and the deferred revenue adjustment referenced above.

In FY’16, the Company’s EBITDA margin was 6.6% and Adjusted EBITDA margin was 14.6%. The year-over-year decline (110 bps) in Adjusted EBITDA margin was caused by the net impact of adverse market movements on the assets and liabilities associated with our deferred compensation programs, foreign currency losses, and the effect of a non-recurring gain in FY’15 relating to an insurance reimbursement for expenses incurred in prior years. The EBITDA margin for the combined Hay Group business was 3.7% and on an adjusted basis, the EBITDA margin was 16.4%, which is consistent with the prior year.

Results by Segment

Selected Executive Search Data

(dollars in millions)

Executive Search

Fee revenue was $159.7 million in Q4 FY’16, an increase of 2.0% (4.5% on a constant currency basis) compared to Q4 FY’15. The overall increase in fee revenue was primarily attributable to higher fee revenues in our North America region.

Operating income was $23.0 million in Q4 FY’16. Operating margin was 14.4% in Q4 FY’16 compared to 20.0% in Q4 FY’15. Operating income and margin were negatively impacted by the foreign currency loss relating to the devaluation of the Venezuelan currency and higher compensation and benefits expense associated with better revenue performance.

EBITDA was $24.6 million in Q4 FY’16 with an EBITDA margin of 15.4% (negatively impacted by the same factors as operating income). Adjusted EBITDA was $31.2 million with an Adjusted EBITDA margin of 19.5%, slightly down from the prior year due primarily to the factors referenced above.

Selected Hay Group Data

(dollars in millions)

Hay Group

Fee revenue was $187.7 million and, on an adjusted basis, fee revenue was $192.8 million in Q4 FY’16 (including $5.1 million in deferred revenue adjustment related to the Hay Group acquisition). The acquisition of Hay Group contributed $114.9 million in fee revenue and $120.0 million on an adjusted basis in Q4 FY’16. Excluding Hay Group revenues, fee revenue was flat quarter-over-quarter and up 1.2% on a constant currency basis.

Operating income was $2.9 million in Q4 FY’16, resulting in an operating margin of 1.5%. The decrease in the margin from the prior year quarter was primarily due to the deferred revenue adjustment related to the Hay Group acquisition, restructuring charges, net, integration/acquisition costs and Venezuelan foreign currency loss.

EBITDA was $10.5 million in Q4 FY’16, with a margin of 5.6%. Adjusted EBITDA was $30.7 million

during Q4 FY’16, at an Adjusted EBITDA margin of 15.9%. As referenced above, the Company continues to make significant progress on the Hay Group integration as reflected in the Q4 FY’16 Adjusted EBITDA margin after only five months of ownership.

The Agreement provides for, among other things: (a) a new senior secured term loan facility in an aggregate principal amount of $275 million (the “Term Facility”); (b) a new senior secured revolving credit facility (the “Revolver”) in an aggregate principal amount of $125 million, (c) annual term loan amortization of 7.5%, 7.5%, 10.0%, 10.0%, and 10.0%, with the remaining principal due at maturity (d) certain customary affirmative and negative covenants, including a maximum consolidated total leverage ratio and a minimum interest coverage ratio, and (e) an expanded definition of permitted add-backs to Adjusted EBITDA in recognition of the accelerated integration actions referenced above. The proceeds from the Agreement will be used to repay existing indebtedness and for working capital and general corporate purposes.

These statements, which include words such as “believes”, “expects” or “likely”, include references to our outlook. Readers are cautioned not to place undue reliance on such statements. Actual results in future periods may differ materially from those currently expected or desired because of a number of risks and uncertainties that are beyond the control of Korn Ferry. The potential risks and uncertainties include those relating to competition, the dependence on attracting and retaining qualified and experienced consultants, our ability to successfully integrate acquired businesses including Hay Group, our ability to recognize the anticipated benefits of the acquisition of Hay Group which may be affected by, among other things, competition, our ability to grow and manage growth profitability, maintain relationships with customers and suppliers and retain key employees, costs related to the acquisition of Hay Group, maintaining our brand name and professional reputation, potential legal liability, the portability of client relationships, global and local political or economic developments in or affecting countries where we have operations, currency fluctuations in our international operations, risks related to growth, alignment of our cost structure with our growth, restrictions imposed by off-limits agreements, reliance on information processing systems, cyber security vulnerabilities, limited protection of our intellectual property, our ability to enhance and develop new technology, our ability to develop new products and services, consolidation of industries we serve, our ability to successfully recover from a disaster or other business continuity problems, changes in our accounting estimates/assumptions, impairment of goodwill and other intangible assets, deferred tax assets, seasonality, our ability to successfully rationalize our cost structure and employment liability risk.

Use of Non-GAAP Financial Measures

This press release contains financial information calculated other than in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). In particular, it includes:

This non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies.

Management believes the presentation of non-GAAP financial measures in this press release provides meaningful supplemental information regarding Korn Ferry’s performance by excluding certain charges and other items that may not be indicative of Korn Ferry’s ongoing operating results. These non-GAAP financial measures are performance measures and are not indicative of the liquidity of Korn Ferry. These charges represent 1) costs we incurred to acquire and integrate the Hay Group acquisition, 2) charges we incurred to restructure the combined company due to the acquisition of Hay Group, 3) foreign currency losses due to the devaluation of the Venezuelan currency and 4) revenue that Hay Group would have realized if not for business combination accounting that requires a company to record the acquisition balance sheet at fair value and write-off deferred revenue where no future services are required to be performed to earn that revenue. As such, reported fee revenue can make fee revenue and operating results appear to fluctuate more than they would if business combination accounting did not require deferred revenue to be written off. Adjusted fee revenue is not a measure that substitutes an individually tailored revenue recognition or measurement method for those of GAAP, rather, it is an adjustment for a short period of time that will provide better comparability in the current and future periods. Management believes the presentation of adjusted fee revenue assists management in its evaluation of ongoing operations and provides useful information to investors because it allows investors to make more meaningful period-to-period comparisons of the Company’s operating results, to better identify operating trends that may otherwise be distorted by write-offs required under business combination accounting and to perform related trend analysis, and provides a higher degree of transparency of information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making. Management will no longer have adjusted fee revenue after Q1 FY’17. The use of these non-GAAP financial measures facilitates comparisons to Korn Ferry’s historical performance. Korn Ferry includes these non-GAAP financial measures because management believes they are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making. In the case of constant currency amounts, management believes the presentation of such information provides meaningful supplemental information regarding Korn Ferry’s performance as excluding the impact of exchange rate changes on Korn Ferry’s financial performance allows investors to make more meaningful period-to-period comparisons of the Company’s operating results, to better identify operating trends that may otherwise be masked or distorted by exchange rate changes and to perform related trend analysis, and provides a higher degree of transparency of information used by management in its evaluation of Korn Ferry’s ongoing operations and financial and operational decision-making.
