KKR Financial Holdings LLC Announces Second Quarter 2013 Financial Results,

Quarterly Distribution of $0.21 per Common Share, and Retirement of Chief Executive Officer

SAN FRANCISCO, July 23, 2013—KKR Financial Holdings LLC (NYSE:KFN) (“KFN” or the “Company”) today announced its results for the second quarter ended June 30, 2013.

Second Quarter 2013 Highlights

·Net income available to common shareholders totaled $79.2 million, an increase of 11% from the same period of 2012.

·Net income per diluted common share totaled $0.39, compared with $0.39 for the comparable prior-year period.

·A quarterly cash distribution of $0.21 per common share was declared for the second quarter of 2013.

·Book value per common share was $10.41 as of June 30, 2013 as compared to book value per common share of $10.16 as of March 31, 2013.

For the three months ended June 30, 2013, the Company reported net income available to common shareholders of $79.2 million, or $0.39 per diluted common share, compared with $71.2 million, or $0.39 per diluted common share, for the comparable prior-year period.  For the six months ended June 30, 2013, the Company reported net income available to common shareholders of $170.8 million, or $0.85 per diluted common share, compared with $159.3 million, or $0.87 per diluted common share, for the comparable prior-year period.

The Company’s second quarter 2013 results included total revenues of $137.2 million, total investment costs and expenses of $65.2 million, total other income of $37.2 million, and total other expenses of $23.2 million. Comparatively, KFN’s second quarter 2012 results reflected total revenues of $140.6 million, total investment costs and expenses of $67.1 million, total other income of $16.5 million, and total other expenses of $18.6 million.

Total revenues of $137.2 million for the second quarter of 2013 represented a decrease of approximately 2% from the comparable prior-year period.  Loan and securities interest income comprised 77% of total revenue and oil and gas revenue comprised 20%, as compared to 91% and 8%, respectively, for the prior-year period.  The Company’s loan and securities interest income declined from $128.4 million for the quarter ended June 30, 2012 to $105.6 million for the quarter ended June 30, 2013.  This resulted primarily from (a) a $12.5 million decline in scheduled and prepayment-related discount amortization from the Company’s loan portfolio and (b) a reduction in the Company’s high-yield bond holdings across its strategies from a par value of $743.7 million to $408.1 million over the year.  This was partially offset by oil and gas revenue, which increased by $16.1 million from the prior-year period.

Total investment costs and expenses of $65.2 million for the second quarter of 2013 represented a decrease of approximately 3% from the comparable prior-year period.  The decline was largely attributable to the retirement and conversion, respectively, of the Company’s 7.0% and 7.5% convertible notes, which accounted for $5.2 million of incremental interest expense during the prior-year period, as well as a $2.6 million reduction in interest expense to affiliates.  This was largely offset by an approximately $7.4 million increase in costs and expenses associated with the Company’s oil and gas portfolio, which grew in size through acquisitions and further development during the twelve months ending June 30, 2013.

Total other income of $37.2 million for the second quarter of 2013 reflected an increase from $16.5 million during the comparable prior-year period, stemming from a higher level of realized and unrealized gains on investments as well as favorable moves in the Company’s derivatives and foreign exchange exposures relative to the prior-year period.

Total other expenses of $23.2 million for the second quarter of 2013 reflected an increase from $18.6 million during the comparable prior-year period, primarily due to a higher level of related party management compensation largely resulting from issuance of the Company’s 7.375% perpetual preferred shares during the first quarter of 2013.

“Market volatility during the second quarter provided us with an attractive window to deploy some of our sizable cash balance.  For example, we took the opportunity to issue a new CLO, capitalizing on a less crowded market to accumulate a more favorably priced loan portfolio than was possible in the first quarter,” said William C. Sonneborn, CEO of KFN.

KKR Financial CLO 2013-1, Ltd.

On June 25, 2013, KFN closed KKR Financial CLO 2013-1, Ltd. (“CLO 2013-1” or the “CLO”), a $519.4 million collateralized loan obligation.  The CLO has a four-year reinvestment period and a two-year non-call period, with a final maturity of July 15, 2025.  The Company retained the entirety of the CLO’s $60.9 million par amount of subordinated notes.  The notes issued by CLO 2013-1 are non-recourse to the Company.  The transaction was approximately 88% ramped as of July 19, 2013.

Book Value

Book value per common share increased 2.5% to $10.41 as of June 30, 2013 from $10.16 as of March 31, 2013.  The increase was predominantly driven by (a) second-quarter net income available to common shareholders of $0.39 per diluted common share and (b) a decrease in the Company’s accumulated other comprehensive loss, a component of shareholders’ equity, of $0.07 per diluted common share primarily as a result of increases in the value of certain interest rate swaps designated as cash flow hedges.  These factors were partially offset by distributions of $0.21 per share paid to common shareholders during the quarter.

Distribution

On July 23, 2013, the Company’s board of directors declared a cash distribution of $0.21 per common share.  The distribution is payable on August 20, 2013 to common shareholders of record as of the close of business on August 6, 2013.

Management Update

The Company also announced today that President, CEO, and Director William Sonneborn, 43, informed the board of directors of his decision to retire after nearly five years at the Company acting in those capacities.  Mr. Sonneborn has served as President and CEO since December 2008 and his decision to retire will bring to a close a remarkable period of extraordinary service to the Company and its shareholders across both financial and strategic metrics.

“We would like to thank Bill Sonneborn for his outstanding service as our CEO,” said Paul Hazen, Chairman of the Board of Directors of KFN. “He took the reins in December 2008 during the most challenging of environments with the credit crisis in full swing and KFN trading below $1.00 per share and having suspended its cash distributions to shareholders. Under Bill’s exceptional leadership, the Company’s share price has increased 15 times in under five years, and Bill leaves KFN well positioned for future opportunities through its strong capital structure and liquidity position.  While we are disappointed in Bill’s decision, we are grateful for all of his contributions and we wish him well in his future endeavors.”

The Company’s board of directors elected Craig J. Farr, 41, to succeed Mr. Sonneborn as President and CEO and as a member of the Company’s board of directors.  Mr. Farr, a member of KKR, joined KKR in 2006 and has served as the Global Head of KKR’s Capital Markets and Origination business.  Prior to joining KKR, Mr. Farr spent 12 years at Citigroup Global Markets Inc. where he was promoted to Managing Director in 2001 and served as Co-Head of North American Equity Capital Markets.  Mr. Farr’s previous responsibilities at Citigroup included Head of U.S. Convertible and Corporate Equity Derivative Origination.  Mr. Farr began his career at Salomon Brothers within the investment banking division.

“We are pleased to have Craig Farr as our new CEO and member of the Board,” said Hazen.  “He is a proven leader and has demonstrated innovative thinking and consistent success in his previous roles within KKR and prior to that at Citigroup.  We look forward to him helping drive continued increases in shareholder value.”

“I have had the pleasure of working with Craig Farr over the past five years and watching him build a strong new business unit within KKR during that period,” Sonneborn said.  “Craig is superbly prepared to guide the continuous evolution of KFN for the best possible outcomes for shareholders.”
