Korn/Ferry International Announces First Quarter Fiscal 2013

Results of Operations

Highlights

Los Angeles, CA, September 5, 2012—Korn/Ferry International (NYSE: KFY), a premier global provider of talent management solutions, announced Q1 FY’13 diluted earnings per share of $0.22 compared to diluted earnings per share of $0.33 in Q1 FY’12.

“The global business environment remains challenging; however I am pleased with Korn/Ferry’s overall strategic progress. The importance of our strategy and business model was further evidenced by the year over year growth of our broader talent management offerings,” said Gary D. Burnison, CEO of Korn/Ferry International. “Continuing with the commitment to our strategy, I am excited about our recent acquisition of Global Novations, a widely respected provider of diversity, inclusion and leadership development offerings. Today’s global organizations put a high premium on cultural dexterity and diverse leaders who can motivate and move workforces across borders. With the world growing flatter, and smaller, and more diverse, Global Novations’ expertise in this fast growing market will be a strong asset to our clients.”

Financial Results

(dollars in millions, except per share amounts)

Fee revenue was $186.7 million in Q1 FY’13 compared to $206.3 million in Q1 FY’12, a decrease of $19.6 million or 10%, (of which $7.5 million related to foreign currency), which reflects a $22.0 million decrease in Executive Recruitment fee revenue partially offset by a $1.7 million and $0.7 million increase in fee revenue in Leadership & Talent Consulting and Futurestep, respectively. The decrease in fee revenue was driven by a 7% decrease in the weighted-average fee billed per engagement and a 3% decrease in the overall number of engagements billed compared to the year-ago fiscal quarter. Weighted-average fee billed per engagement is impacted by the mix of engagements by geography and segment, and fluctuating foreign currencies. The decrease in fee revenue was driven by decreases in the industrial, financial services and consumer sectors. On a constant currency basis, fee revenue decreased $12.1 million, or 6%.

Compensation and benefit expenses were $128.0 million in Q1 FY’13, a decrease of $9.4 million, or 7%, (of which $4.6 million related to foreign currency) compared to $137.4 million in Q1 FY’12. The decrease in compensation and benefit expenses was primarily due to a 6% decrease in performance related compensation expense, salaries and related payroll taxes in Q1 FY’13 compared to Q1 FY’12 primarily due to a decrease in the number of consultants compared to Q1’ FY12. On a constant currency basis, compensation and benefits decreased $4.8 million, or 3%.

General and administrative expenses were $33.4 million in Q1 FY’13, a decrease of $1.4 million, or 4%, from $34.8 million in Q1 FY’12. This decrease is attributable to a decrease in travel related expenses and bad debt expense. The decrease in travel related expenses was due to the ongoing cost control initiatives implemented by the Company to reduce costs while the decrease in bad debt expense is due to a decline in historical bad debt trends. On a constant currency basis, general and administrative expenses increased $0.7 million, or 2%.

Operating income was $17.0 million in Q1 FY’13 compared to operating income of $25.9 million in Q1 FY’12, a decrease of $8.9 million, or 34%.

Balance Sheet and Liquidity

Cash and marketable securities were $332.9 million and $281.2 million at July 31, 2012 and 2011, respectively, compared to $417.7 million at April 30, 2012. Cash and marketable securities include $91.1 million and $82.2 million held in trust for deferred compensation plans at July 31, 2012 and April 30, 2012, respectively. Cash and marketable securities decreased by $84.8 million from April 30, 2012, mainly due to the payment of FY’12 annual bonuses in Q1 FY’13, partially offset by cash provided by operating activities.

Results by Segment

Beginning Q1 FY’13, the Company will begin 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.

Fiscal 2013 First Quarter Results – Executive Recruitment

Fee revenue was $127.4 million in Q1 FY’13, a decrease of $22.0 million, or 15%, when compared to fee revenue of $149.4 million in Q1 FY’12. Fee revenue decreased in all regions due to a 14% decrease in the number of executive recruitment engagements billed when compared to Q1 FY’12. On a constant currency basis, fee revenue decreased $16.8 million, or 11%.

Operating income was $22.4 million in Q1 FY’13 compared to operating income of $33.1 million in Q1 FY’12, a decrease of $10.7 million or 32%. This decrease is primarily attributed to the $22.0 million decrease in fee revenue in Q1 FY’13 as compared to Q1 FY’12, which was partially offset by a $10.3 million and $1.0 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 and a 6% decrease in salaries and related payroll taxes due in large part to a 7% decline in the average number of consultants in Q1 FY’13 as compared to Q1 FY’12. The decrease in general and administrative expense was primarily due to a decrease in premise and office expense of $0.6 million and bad debt expense of $0.5 million. The decrease in premise and office expense was due to lower maintenance costs while the decrease in bad debt expense was due to a decline in historical bad debt trends.

Selected Leadership & Talent Consulting Data

(dollars in millions)

Fiscal 2013 First Quarter Results – Leadership & Talent Consulting

Leadership & Talent Consulting serves as a bridge between a client’s business strategy and their talent strategy. Leadership & Talent Consulting combines intellectual content with traditional consulting services such as CEO & top team effectiveness, integrated talent management as well as leadership development & enterprise learning. Fee revenue was $28.4 million in Q1 FY’13, an increase of $1.7 million, or 6%, from $26.7 million in Q1 FY’12. The improvement in fee revenue was driven by an increase in fee revenue productivity per consultant and broad based client demand as demonstrated by an increase in the number of consulting clients. On a constant currency basis, fee revenue increased $2.5 million, or 9%.

Operating income was $4.3 million in Q1 FY’13 compared to operating income of $2.0 million in Q1 FY’12, an increase of $2.3 million, primarily due to the increase in fee revenue as described above, as well as slightly lower operating expenses.

Fiscal 2013 First Quarter Results – Futurestep

Fee revenue was $30.9 million in Q1 FY’13, an increase of $0.7 million, or 2%, from $30.2 million in Q1 FY’12. The improvement in fee revenue was driven by an 11% increase in the number of engagements billed, which was partially offset by an 8% decrease in the weighted average fee per engagement. The increase in fee revenue was due to an increase in recruitment process outsourcing partially offset by a decrease in middle management recruitment. On a constant currency basis, fee revenue increased $2.2 million, or 7%.

Operating income was $3.2 million in Q1 FY’13 compared to operating income of $2.8 million in Q1 FY’12, an increase of $0.4 million, or 14%.

Outlook

We are confronting uncertainty and challenges in the global economy and financial markets, resulting in our clients operating with an abundance of caution when it comes to hiring decisions. As such, it continues to be difficult to accurately forecast business results. In light of these headwinds, the Company plans to take certain actions in Q2 FY’13 to better align its cost structure with expected revenue levels. Assuming economic conditions, financial markets and foreign exchange rates remain steady, Q2 FY’13 fee revenue is likely to be in the range of $180 million to $195 million and adjusted diluted earnings per share is likely to be in the range of $0.16 to $0.22, excluding $0.14 to $0.28 of estimated non-recurring costs. As measured by generally accepted accounting principles diluted earnings/loss per share is likely to be in the range of diluted loss per share of $0.12 to diluted earnings per share of $0.08.

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.
