Fortress Reports Second Quarter 2013 Results and Announces Dividend of $0.06 per Share

New York, NY. August 1, 2013 – Fortress Investment Group LLC (NYSE: FIG) today reported its second quarter 2013 financial results.

FINANCIAL SUMMARY

BUSINESS HIGHLIGHTS

1

“We had an outstanding second quarter and first half of the year, founded on the strength of investment performance we delivered for our limited partners,” said Randal Nardone, Chief Executive Officer. “Looking ahead, we see uniform strength in the leading indicators of future performance – investment returns, capital formation, new business initiatives and embedded value. We continue to see substantial upside for our limited partners and our shareholders. I look forward to serving as Fortress’s Chief Executive Officer at this very exciting time for our company.”

SUMMARY FINANCIAL RESULTS

Fortress’s business model is highly diversified, and management believes that this positions the company to capitalize on opportunities for investing, capital formation and harvesting profits that can occur at different points in any cycle for our individual businesses. Fortress’s business model generates stable and predictable management fees, which is a function of the majority of Fortress’s alternative AUM residing in long-term investment structures. Fortress’s alternative investment businesses also generate variable incentive income based on performance, and this incentive income can contribute meaningfully to financial results. Balance sheet investments represent a third component of Fortress’s business model, and the company has built substantial value in these investments, which are made in Fortress funds alongside the funds’ limited partners.

The table below summarizes Fortress’s operating results for the second quarter ended June 30, 2013. The consolidated GAAP statement of operations and balance sheet are presented at the end of this press release.

CONSOLIDATED GAAP RESULTS

Fortress recorded a GAAP net loss of $2 million, or $0.01 loss per diluted share, for the second quarter of 2013, compared to GAAP net income of $14 million, or $0.12 loss per diluted share, for the second quarter of 2012. Our diluted earnings per share for all periods presented includes the income tax effects to net income (loss) attributable to Class A shareholders from the assumed conversion of Fortress Operating Group units and fully vested restricted partnership units to Class A shares.

The year-over-year decline in Fortress’s GAAP net income was primarily driven by higher compensation and benefits, which resulted in a $38 million increase in GAAP expenses, partially offset by higher GAAP revenues.

CONSOLIDATED SEGMENT RESULTS (NON-GAAP)

This section provides information about each of Fortress’s businesses: (i) Credit, (ii) Private Equity, (iii) Liquid Hedge Funds, and (iv) Logan Circle.

Fortress uses “distributable earnings,” or DE, as the primary metric to manage its businesses and gauge the company’s performance, and it uses DE exclusively to report segment results. Consolidated segment results are non-GAAP information and are not presented as a substitute for Fortress’s GAAP results. Fortress urges you to read “Non-GAAP Information” below.

Pre-tax DE was $148 million in the second quarter of 2013, up from $50 million in the second quarter of 2012. The year-over-year increase was primarily due to substantially higher incentive income generated by our funds, partially offset by higher compensation related expenses.

Incentive income recorded in the second quarter of 2013 totaled $199 million, a fourfold increase from $47 million recorded in the second quarter of 2012. Every alternative investment business generated higher incentive income. Additionally, Fortress had $754 million in gross undistributed, unrecognized incentive income based on investment valuations as of June 30, 2013. This includes $669 million from our funds and $85 million from options in our permanent capital vehicles.

3

Management fees were $129 million in the second quarter of 2013, up from $114 million in the second quarter of 2012, primarily due to higher management fees from the Private Equity Funds, Liquid Hedge Funds, Credit Private Equity (“PE”) Funds and Logan Circle, partially offset by lower management fees from the Credit Hedge Funds. Notably, 80% of the alternative AUM at quarter end were in funds with long-term investment structures, which provides for a stable, predictable base of management fees.

The Company’s segment revenues and distributable earnings will fluctuate materially depending upon the performance of its funds and the realization events within its private equity businesses, as well as other factors. Accordingly, the revenues and distributable earnings in any particular period should not be expected to be indicative of future results.

ASSETS UNDER MANAGEMENT

As of June 30, 2013, AUM totaled $54.6 billion, down slightly from $55.6 billion as of March 31, 2013. During the second quarter of 2013, Fortress raised $1.2 billion of capital and equity that was directly added to AUM, had a $0.3 billion increase in invested capital and recorded $0.1 billion of net client inflows for Logan Circle. These increases to AUM were offset by (i) a $1.5 billion reduction in Castle AUM related to Eurocastle Investment Limited’s recapitalization, (ii) $0.6 billion of capital distributions to investors, (iii) $0.3 billion of payments to Credit Hedge Fund investors from redeeming capital accounts and (iv) $0.2 billion of Hedge Fund redemptions. As of June 30, 2013, the Credit PE Funds and Private Equity Funds had approximately $5.9 billion and $0.7 billion of uncalled capital, respectively, that will become AUM if deployed/called. Uncalled capital in our Credit PE Funds includes $1.2 billion that is only available for follow-on investments, management fees and other fund expenses.

BUSINESS SEGMENT RESULTS

Below is a discussion of second quarter 2013 segment results and business highlights.

Credit:

(See supplemental data on pages 18-19 for more detail on Credit results)

The Credit business, which includes our Credit Hedge Funds and Credit PE Funds, generated pre-tax DE of $53 million in the second quarter of 2013, up from $25 million in the second quarter of 2012. The year-over-year improvement in DE was primarily driven by $101 million of incentive income recorded during the second quarter, comprising $64 million from hedge funds and $37 million from private-equity style funds.

4

Our flagship Credit Hedge Funds continued to build on their track record of consistent outperformance in the second quarter. DBSO LP recorded a net return of 5.2% in the quarter and 9.4% year-to-date through June 30, 2013. Positive fund performance contributed to $167 million of third-party commitments in the quarter, totaling $242 million in the first half of 2013. At quarter end, the Credit Hedge Funds had $4.8 billion of incentive eligible NAV above performance thresholds and eligible to generate additional incentive income.

Our Credit PE Funds also delivered strong investment performance during the quarter, which led to an increase in both realized and unrealized incentive income compared to the previous year. Credit PE realized incentive income totaled $37 million in the quarter, compared to $14 million in the second quarter of 2012. Even with continued realization activity, unrealized Credit PE incentive income increased to $569 million at the end of the quarter, up $24 million from the previous quarter and up $223 million from the second quarter of 2012. The Credit Opportunities Fund, Credit Opportunities Fund II and Japan Opportunity Fund had net annualized inception-to-date IRRs of 26.2%, 18.7% and 20.7%, respectively, through June 30, 2013. Notably, all of our flagship Credit Opportunities Funds and Japan Opportunities Funds are valued above their preferred thresholds and are eligible to generate incentive income.

During the quarter, the Credit PE Funds deployed $0.2 billion of dry powder for investments and distributed $0.4 billion of capital back to limited partners. In the first half of 2013, Credit PE Funds deployed over $0.5 billion of capital and returned nearly $1.4 billion back to limited partners. Total Credit Private Equity dry powder – capital committed to the funds but not invested and generating management fees – was $5.9 billion as of quarter end. Of that total, $1.2 billion is only available for follow-on investments, management fees and other fund expenses.

“Across our Credit Private Equity and Hedge Funds, we again achieved our overriding objective of delivering strong performance for our limited partners,” said Pete Briger, Fortress co-Chairman and Credit business co-CIO. “We have seen only marginal, if any, improvement in pricing dynamics and opportunities for new investments in the market today, and anticipate that virtually all near-term opportunities with the potential to meet our return targets will be idiosyncratic in nature and privately sourced. Given the enormous global backdrop of potential opportunities, we are pleased that our limited partners have entrusted us with ample capital to deploy if and when this potential becomes actionable. We will remain disciplined, patient and opportunistic fiduciaries throughout the cycle.”

Private Equity:

(See supplemental data on page 17 for more detail on Private Equity results)

The Private Equity business, which includes Private Equity Funds and Castles, had pre-tax DE of $30 million in the second quarter of 2013, up from $27 million in the second quarter of 2012. The increase in DE was primarily due to higher incentive income, partially offset by lower management fees from the Castles. The PE Funds recorded $5 million of incentive income during the quarter, primarily related to the liquidation of remaining investments held within Fund I. Since its inception in 1999, Fund I generated $345 million of incentive income and had a net annualized inception-to-date IRR of 25.7% through June 30, 2013. The Castles recorded $1 million of incentive income during the quarter, primarily attributable to New Residential (NYSE: NRZ), our newly launched publicly traded residential-focused mortgage REIT.

Private Equity Fund valuations appreciated 1.8% in the quarter and 6.9% year-to-date through June 30, 2013. Valuation appreciation in the quarter was driven by certain of our private portfolio company investments primarily held within Fund IV and Fund V. At quarter end, all of our main PE funds were valued above cost and in aggregate were valued at a multiple of 1.4x invested capital.

The Private Equity business raised $333 million of capital in the quarter, bringing capital raised year-to-date through June 30, 2013 to over $1.3 billion. Fundraising activity in the quarter included $198 million of permanent equity capital for Newcastle (NYSE: NCT) and $135 million of permanent equity capital for Eurocastle (Euronext Amsterdam: ECT). Subsequent to quarter end, we held the first and final close for Fortress MSR Opportunities Fund II (“MSR Fund II”) at its cap of $1.1 billion. MSR Fund II is a successor fund to the Fortress MSR Opportunities Fund I, which closed in August 2012 with $0.6 billion in commitments.

During the quarter, Newcastle completed the spin off of all of its investments in MSRs and certain other residential assets into a new publicly traded REIT, New Residential Investment Corp. New Residential is externally managed by an affiliate of Fortress and primarily targets opportunistic investments in excess MSRs, RMBS, residential mortgage loans and other related assets. Newcastle remains focused on harvesting its existing commercial real estate debt investments, while investing opportunistically in senior housing and other assets. At quarter end, Newcastle and New Residential had AUM of $1.5 billion and $1.2 billion, respectively.

During the quarter, Eurocastle completed a recapitalization and conversion of its outstanding convertible debt. As part of the recapitalization, Fortress and Eurocastle entered into an amended management agreement that reduced the AUM used to compute Eurocastle’s management fees from €1.5 billion to €0.3 billion as of April 1, 2013. The agreement also reduced the earnings thresholds required for Fortress to earn incentive income from Eurocastle. As of June 30, 2013, Eurocastle had $0.5 billion of AUM.

In July 2013, Fortress and its affiliates sold 20 million shares of GAGFAH (Xetra: GFJ) at a price of €8.81 per share. The share sale generated $230 million of proceeds and reduced Fortress’s cumulative share ownership of GAGFAH from 61% to 49%.

“On all fronts, it was an active and rewarding quarter for our business and our investors, and we continue to track well against the ambitious objectives we set at the beginning of the year,” said Wes Edens, Fortress co-Chairman and Private Equity CIO. “We’ve achieved milestones at both ends of the investment cycle, liquidating our first ever private equity fund at a 2.8 times return, and raising over $2.4 billion in new capital in our sector-focused funds and permanent equity vehicles through July. With an outstanding core of portfolio companies, we expect to deliver attractive returns in our remaining general funds. Looking at the landscape for new investments, we couldn’t be more excited about the scale of opportunities and our competitive position in the sectors of our main focus today.”

Liquid Hedge Funds:

(See supplemental data on page 20 for more detail on Liquid Hedge Funds results)

The Liquid Hedge Funds generated pre-tax DE of $64 million in the second quarter of 2013, compared to $3 million in the second quarter of 2012, primarily due to a substantial increase in incentive income. Incentive income generated in the second quarter totaled $92 million, nearly three times the amount generated in the first quarter of 2013 and 35% more than was generated in all of 2012.

Net returns for the second quarter of 2013 for the Fortress Macro Funds, Fortress Asia Macro Funds, Fortress Partners Funds and Fortress Convex Asia Funds were 9.1%, 9.8%, (2.0)% and 1.6%, respectively. Net returns year-to-date through July 26, 2013 for the Fortress Macro Funds, Fortress Asia Macro Funds and Fortress Convex Asia Funds were 11.6%, 11.8% and 0.0%, respectively.

Substantially all main Fortress Macro Fund and Fortress Asia Macro Fund capital was above high water marks at quarter end. In aggregate, approximately $4.7 billion of Liquid Hedge Fund capital was above respective high water marks at the end of the quarter, a $3.7 billion increase from the end of the second quarter of 2012.

Liquid Hedge Funds ended the quarter with $6.5 billion of AUM, up 18% from the previous quarter, primarily due to $726 million of capital raised and $466 million of performance appreciation, partially offset by $177 million of redemptions. As of June 30, 2013, there were $441 million Liquid Hedge Fund redemption notices outstanding, of which $171 million will be paid primarily within one quarter and $270 million will be paid in the first quarter of 2014 and thereafter.

Subsequent to quarter end, the Liquid Hedge Funds raised nearly $470 million of additional capital, which will be added to AUM in the third quarter of 2013.

“We’ve had an exceptional 2013 in the Fortress Macro and Fortress Asia Macro Funds, with both strategies delivering record net returns for our investors in the second quarter, and approximately 12% net returns through July 26th,” said Mike Novogratz, Fortress Principal and co-CIO of Fortress Macro Funds. “As always, there is significant correlation between investment returns, financial performance, fundraising and AUM growth. Our business delivered its second highest quarter of distributable earnings, driven by over $90 million in incentive income. Limited partners have committed nearly $2 billion in new capital to our strategies through July, and the Asia Macro Fund met its full year subscription target as of July 1, with total AUM of $1.7 billion. With a constructive view of the macro environment taking shape, and $5 billion in capital eligible to generate incentive income, we’re enthusiastic about prospects to deliver strong results for our investors and Fortress shareholders going forward.”

Logan Circle:

(See supplemental data on page 21 for more detail on Logan Circle results)

Logan Circle, our traditional asset management business, recorded a pre-tax DE loss of $3 million in the second quarter of 2013, compared to a pre-tax DE loss of $2 million in the second quarter of 2012. The year-over-year change was primarily due to an increase in operating expenses related to the launch of the new growth equities business, partially offset by increased management fees.

Logan Circle ended the quarter with $21.4 billion in AUM, an 18% increase compared to the previous year but a 2% decrease compared to the first quarter of 2013. The quarter-over-quarter decline in AUM was primarily due to market-driven valuation declines of $664 million, partially offset by net client inflows of $124 million. While second quarter inflows were somewhat muted compared to $1.2 billion of net client inflows in the first quarter of 2013, we believe Logan Circle has a strong pipeline moving into the 2nd half of 2013.

Investment performance has been solid in the first half of the year as 11 of 16 Logan Circle fixed income strategies outperformed their respective benchmarks year-to-date through June 30, 2013. Notably, Logan Circle has continued to deliver consistent outperformance during and since the financial crisis in 2008. For the trailing five-year period, 12 of 13 Logan Circle fixed income strategies have outperformed their respective benchmarks and eight are ranked in the top quartile of performance for their competitor universe.

In July 2013, Logan Circle launched a new growth equities investment business that is focused on investing and managing concentrated portfolios of publicly traded U.S. equities for institutional clients. The business currently manages four investment strategies, seeded by Fortress, which vary in concentration and capitalization focus.

“We’ve had a solid year of performance for our investors, with the majority of our composites outperforming their respective benchmarks, despite a generally very challenging fixed-income market in the second quarter,” said Jude Driscoll, Logan Circle Partners Chief Executive Officer. “Inception-to-date performance remains exceptional, with 15 out of 16 fixed income strategies outperforming benchmarks. This speaks very powerfully to the performance-driven culture of Logan Circle, and has helped drive asset growth of over 20% on a compounded annualized basis since we became part of Fortress in 2010. We expect that our core fixed income strategies will continue to attract new clients and deepen existing relationships. We also anticipate that Logan’s growth can take on a new trajectory as we continue to evolve into a broader asset management platform. The addition of a high quality growth equities business is a significant milestone in that evolution, and we have seen significant interest in the four distinct equity strategies we have introduced.”

Principal Investments:

The Principal Investments segment, which is comprised of Fortress’s investments in its own funds, generated pre-tax DE of $4 million in the second quarter of 2013, compared to a pre-tax DE loss of $3 million in the second quarter of 2012. This year-over-year improvement is largely a result of increased realization events in our funds and a decline in interest expense.

As of June 30, 2013, Principal Investments had segment assets (excluding cash and cash equivalents) totaling $1.3 billion, including $1.2 billion of investments in Fortress funds and $98 million of investments in options. As of June 30, 2013, Fortress had a total of $164 million of outstanding commitments to its funds.

In addition, as of June 30, 2013, the net asset value of Fortress’s Principal Investments exceeded its segment cost basis by $541 million, representing net unrealized gains that have not yet been recognized for segment reporting purposes.

As part of GAGFAH’s secondary offering in July 2013, Fortress sold 862,383 shares of GAGFAH held on its balance sheet. The share sale resulted in realized investment gains of $5.5 million that will be recognized in DE in the third quarter of 2013.

LIQUIDITY & CAPITAL

As of June 30, 2013, Fortress had cash and cash equivalents of $293 million and outstanding debt obligations of $89 million. Total debt was down $20 million from the previous quarter due to scheduled promissory note payments to a former Principal related to the exchange of his equity interests in Fortress in December 2012. In July 2013, Fortress repaid the remaining $89 million, plus accrued interest, on the promissory note. As such, the note is no longer outstanding.

DIVIDEND

Fortress’s Board of Directors declared a second quarter 2013 cash dividend of $0.06 per dividend paying share. The dividend is payable on August 16, 2013 to Class A shareholders of record as of the close of business on August 13, 2013.

9

The declaration and payment of any dividends are at the sole discretion of the Board of Directors, which may decide to change its dividend policy at any time. Please see below for information on the U.S. federal income tax implications of the dividend.

NON-GAAP INFORMATION

Distributable earnings, or DE, is a primary metric used by management to measure Fortress’s operating performance. Consistent with GAAP, DE is the sole measure that management uses to manage, and thus report on, Fortress’s segments, namely: Private Equity, Castles, Credit Hedge Funds, Credit Private Equity Funds, Liquid Hedge Funds, Logan Circle and Principal Investments. DE differs from GAAP net income in a number of material ways. For a detailed description of the calculation of DE, see note 11 to the financial statements included in the Company’s most recent annual report on Form 10-K, or note 10 to the financial statements included in the Company’s most recent quarterly report on Form 10-Q.

Fortress aggregates its segment results to report consolidated segment results, as shown in the table under “Summary Financial Results” and in the “Total” column of the table under “Consolidated Segment Results (Non-GAAP).” The consolidated segment results are non-GAAP financial information. Management believes that consolidated segment results provide a meaningful basis for comparison among present and future periods. However, consolidated segment results should not be considered a substitute for Fortress’s consolidated GAAP results. The exhibits to this release contain reconciliations of the components of Fortress’s consolidated segment results to the comparable GAAP measures, and Fortress urges you to review these exhibits.

U.S. FEDERAL INCOME TAX IMPLICATIONS OF DIVIDEND

For U.S. federal income tax purposes, the dividend declared in July 2013 will be treated as a partnership distribution. Based on the best information currently available, when calculating withholding taxes, 2.90 cents of the per share distribution will be treated as U.S. source interest income. Accordingly, for non-U.S. holders of Class A shares, unless an exception to withholding tax applies, the distribution will be subject to a U.S. federal withholding tax of 0.870 cents per share. Non-U.S. holders of Class A shares are generally subject to U.S. federal withholding tax at a rate of 30% (subject to reduction by applicable treaty or other exception) on certain types of U.S. source income realized by the Company. With respect to interest, however, no withholding is generally required if proper certification (on an IRS Form W-8) of a beneficial owner’s foreign status has been filed with the withholding agent. In addition, non-U.S. holders must generally provide the withholding agent with a properly completed IRS Form W-8 to obtain any reduction in withholding.
