Korn/Ferry International Announces Second Quarter Fiscal 2013 Results of Operations

Highlights

Los Angeles, CA, December 6, 2012 - Korn/Ferry International (NYSE: KFY), a premier global provider of talent management solutions, announced second quarter adjusted diluted earnings per share of $0.25 excluding net restructuring charges of $15.5 million compared to diluted earnings per share of $0.32 in the three months ended October 31, 2011. Including net restructuring charges, diluted earnings per share was $0.03 in the three months ended October 31, 2012.

“I am pleased with the sequential growth of the Company overall, and once again, year-over-year growth within our broader talent management offerings,” said Gary D. Burnison, CEO of Korn/Ferry International. “In addition, I am excited about the pending acquisition of PDI Ninth House, which greatly accelerates Korn/Ferry’s vision of being the world’s premier talent solutions advisor. CEOs today are waging a fight for growth. Their workforce is global, borderless and far more dynamic and diverse than in the past. In this decade, successful companies will be those that can more effectively link their business and talent strategies. This acquisition provides significantly more depth and scale toward Korn/Ferry being that linkage – the bridge between a CEO’s vision and their people strategy.”

Financial Results

(dollars in millions, except per share amounts)

Results for the three months ended October 31, 2012

Fee revenue was $196.2 million in the three months ended October 31, 2012, a decrease of $4.0 million, or 2%, compared to the year-ago quarter, (foreign exchange rates negatively impacted fee revenue by $4.7 million), which reflects a $14.8 million decrease in Executive Recruitment fee revenue partially offset by a $9.4 million and $1.4 million increase in fee revenue in Leadership & Talent Consulting and Futurestep, respectively. The acquisition of Global Novations on September 1, 2012, contributed $5.2 million to the increase in fee revenue in Leadership & Talent Consulting.

The decrease in fee revenue for the three months ended October 31, 2012 resulted from a 7% decrease in the overall number of engagements billed compared to the year-ago quarter, partially offset by a 6% increase in the weighted-average fee billed per engagement. While fee revenue from the technology and consumer sectors increased, the increases from these sectors was more than offset by decreases in the industrial, financial services and life science/healthcare sectors. On a constant currency basis, fee revenue increased $0.7 million.

Compensation and benefit expenses were $133.1 million in three months ended October 31, 2012, an increase of $1.6 million, or 1%, compared to the year-ago quarter. Compensation and benefit expenses increased primarily because of a $3.2 million increase due to the acquisition of Global Novations. Offsetting this increase was a decrease in salaries and related payroll taxes due to lower consultant headcount and a decline in performance related compensation expense. On a constant currency basis, compensation and benefits increased $5.3 million, or 4%.

General and administrative expenses were $33.4 million in the three months ended October 31, 2012, a decrease of $0.8 million, or 2%, from the year-ago quarter. This decrease is primarily attributable to a decrease in professional service fees and business development expenses, offset by a reduction in a contingent consideration liability relating to a prior acquisition that was recorded in the three months ended October 31, 2011. On a constant currency basis, general and administrative expenses increased $0.2 million.

As discussed during our first quarter earnings call, during the three months ended October 31, 2012, the Company took steps to rationalize its cost structure, and as a result recorded restructuring charges of $11.3 million to reduce its workforce and $5.2 million relating to the consolidation of premises. This restructuring

expense was partially offset by a $1.0 million recovery (legal settlement related to premises) from a previous restructuring action resulting in net restructuring costs of $15.5 million. These actions are expected to result in annualized cost savings of approximately $20 million to $23 million, with the majority of these savings starting in the third quarter.

Excluding these restructuring charges, operating income was $18.3 million, during the three months ended October 31, 2012, a decrease of $7.1 million, or 28%, compared to the year-ago quarter. Including restructuring charges, operating income was $2.8 million in three months ended October 31, 2012, a decrease of $22.6 million, or 89%, compared to the year-ago quarter. Adjusted operating margin declined by 3.4 percentage points primarily due to a change in mix of fee revenues by operating segment, lower operating profits in Executive Recruitment and the impact of the change in market value of certain deferred compensation liabilities, partially offset by a decline in global expenses of the Company recorded in the Corporate segment.

Balance Sheet and Liquidity

Cash and marketable securities were $331.8 million and $318.1 million at October 31, 2012 and 2011, respectively, compared to $417.7 million at April 30, 2012. Cash and marketable securities include $93.9 million and $78.4 million held in trust for deferred compensation plans at October 31, 2012 and 2011, respectively, compared to $82.2 million at April 30, 2012. Cash and marketable securities decreased by $85.9 million from April 30, 2012, mainly due to the payment of FY’12 annual bonuses in Q1 FY’13 and the payment for the acquisition of Global Novations in the three months ended October 31, 2012, partially offset by cash provided by operating activities.

Results by Segment

In Q1 FY’13, the Company began reporting its Leadership & Talent Consulting business as a separate segment. The Company now operates in three global business segments: Executive Recruitment, Leadership & Talent Consulting and Futurestep. This change has no impact on previously reported consolidated net income or earnings per share.

Selected Executive Recruitment Data

(dollars in millions)

Results for the three months ended October 31, 2012 – Executive Recruitment

Fee revenue was $127.8 million in the three months ended October 31, 2012, a decrease of $14.8 million, or 10%, when compared with the year-ago quarter. Fee revenue decreased in all regions due to a 10% decrease in the number of executive recruitment engagements billed when compared to the year-ago quarter. On a constant currency basis, fee revenue decreased $11.5 million, or 8%.

Excluding restructuring charges, operating income was $21.2 million in the three months ended October 31, 2012, a decrease of $10.9 million, or 34%, compared year-ago quarter. This decrease is primarily attributable to the decrease in fee revenue in the three months ended October 31, 2012 as compared to the year-ago quarter, partially offset by a $2.3 million and $1.8 million decrease in compensation and benefits expense and general and administrative expenses, respectively, in the same period. The decrease in compensation and benefits expense primarily resulted from a decrease in performance related compensation expense due to a decline in the average number of consultants and a decline in fee revenue in the three months ended October 31, 2012 compared to the year-ago quarter. The decrease in general and administrative expenses was primarily due to a decrease in bad debt expense, due to a decline in historical bad debt trends, and a decline in travel expenses due to the ongoing cost control initiatives. Including restructuring charges of $10.7 million, operating income was $10.5 million in three months ended October 31, 2012, a decrease of $21.6 million, or 67%, compared to the year-ago quarter.

Selected Leadership & Talent Consulting Data

(dollars in millions)

Results for the three months ended October 31, 2012 – Leadership & Talent Consulting

Leadership & Talent Consulting serves as a bridge between a client’s business strategy and their talent strategy. Leadership & Talent Consulting utilizes intellectual property in the delivery of talent management consulting services including CEO and top team effectiveness, leadership development and enterprise learning. Fee revenue was $38.4 million in the three months ended October 31, 2012, an increase of $9.4 million, or 32%, from the year-ago quarter. The improvement in fee revenue was driven by an increase in consulting fee revenue mainly in Europe and Latin America and broad based client demand as demonstrated by the increase in the number of consulting clients. Also contributing to the increase in fee revenue was the acquisition of Global Novations on September 1, 2012 which contributed $5.2 million in fee revenue for the three months ended October 31, 2012. On a constant currency basis, fee revenue increased $10.0 million, or 34%.

Excluding restructuring charges, operating income was $6.9 million in the three months ended October 31, 2012, an increase of $2.7 million, or 64%, compared to the year-ago quarter. The increase is primarily attributed to the increase in fee revenue, offset by an increase in compensation and benefits expense primarily from the acquisition of Global Novations and an increase in performance related compensation expense due to an increase in the average number of consultants and the increase in fee revenue. General and administrative expenses also increased during the same period primarily due to an increase in premise and office expense due in large part to the acquisition of Global Novations. Including restructuring charges of $0.7 million, operating income was $6.2 million, an increase of $2.0 million, or 48%, compared to the year-ago quarter.

Selected Futurestep Data

(dollars in millions)

Results for the three months ended October 31, 2012 – Futurestep

Fee revenue was $30.0 million in the three months ended October 31, 2012, an increase of $1.4 million, or 5%, compared to the year-ago quarter. The improvement in fee revenue was driven by a 4% increase in the number of engagements billed and a 1% increase in the weighted average fee per engagement. The increase in fee revenue was due to an increase in recruitment process outsourcing and in middle management recruitment. On a constant currency basis, fee revenue increased $2.2 million, or 8%.

Excluding restructuring charges, operating income was $3.3 million in the three months ended October 31, 2012, an increase of $0.5 million, or 18%, compared to the year-ago quarter. The increase in operating income was due primarily to the increase in fee revenue, partially offset by an increase in compensation and benefit expenses due in large part to the increase in performance related compensation expense. Including restructuring charges of $3.1 million, operating income was $0.2 million, a decrease of $2.6 million, or 93%, compared to the year-ago quarter.

Outlook

Assuming worldwide economic conditions, financial markets and foreign exchange rates remain steady, and excluding the impact of the pending acquisition of PDI Ninth House, Q3 FY’13 adjusted stand-alone fee revenue is likely to be in the range of $188 million to $201 million, and adjusted stand-alone diluted earnings per share is likely to be in the range of $0.26 to $0.34.⁽¹⁾ Assuming a December 31^st close, we expect to begin the integration of PDI Ninth House into our global Leadership & Talent Consulting segment in January 2013. For the month of January 2013 (a seasonally low month), PDI Ninth House is expected to contribute between $6 million and $7 million of fee revenue and, prior to the effects of purchase accounting amortization, if any, breakeven operating earnings. The integration of PDI Ninth House will involve workforce alignment, consolidation of office space and elimination of redundant general and administrative expenses. In order to achieve these synergies, we estimate in Q3 FY’13 we will incur incremental charges relating to the integration between $2.5 million and $3.5 million. In addition to these incremental charges, we also expect to incur incremental legal and professional fees associated with the acquisition in Q3 FY’13 of approximately $2.5 million (an aggregate of $0.06 to $0.08 on a per share basis).

On a consolidated combined basis, assuming the pending addition of PDI Ninth House, Q3 FY’13 consolidated fee revenue as measured by generally accepted accounting principles is likely to be in the range of $194 million to $208 million, and excluding the $0.06 to $0.08 of estimated incremental charges relating to the integration as well as the incremental legal and professional fees associated with the pending acquisition, adjusted consolidated combined diluted earnings per share is likely to be in the range of $0.26 to $0.34⁽²⁾, with diluted earnings per share as measured by generally accepted accounting principles likely to be in the range of $0.18 to $0.28.

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. The use of these non-GAAP financial measures facilitate 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. In the case of adjusted stand-alone results, management believes the presentation of such information provides investors with the ability to make period-to-period comparisons of Korn/Ferry’s operating results, net of the acquisition of PDI Ninth House. Management believes the presentation of adjusted consolidated combined diluted earnings per share provides investors with greater visibility into the impact of the PDI Ninth House acquisition without regard to incremental charges and transaction costs.
