MF Global Reports Third Quarter 2011 Results

Improved earnings performance on lower leverage; increased revenue per employee

NEW YORK, February 3, 2011 – MF Global Holdings Ltd. (NYSE: MF), a broker-dealer providing trading and hedging solutions, today reported financial results for the third fiscal quarter ended December 31, 2010.

Third Quarter Highlights

“The opportunity ahead is significant and the roadmap to achieve our objectives is clear,” said Jon S. Corzine, chairman and chief executive officer, MF Global. “MF Global has taken the

necessary steps to define our future and I believe we have crafted a strategic path forward to transition from a broker, to a broker-dealer, and eventually to a commodities and capital markets focused global investment bank.”

Mr. Corzine continued, “By aligning ourselves around client needs, our business model will focus on four main areas – institutional capital markets, retail services, transaction services and asset management. While some of these areas currently exist, others need retooling, and some will be built or acquired over time.”

“This transformation can fundamentally change our growth trajectory and profitability profile by delivering our clients a more comprehensive package of risk intermediation services. I believe our new model will create a growing and diversified revenue base, which will allow MF Global to deliver stable, double-digit returns to shareholders,” Mr. Corzine concluded.

Third Quarter 2011 Financial Results

Revenue, net of interest and transaction-based expenses (net revenue), was $246.8 million in the third quarter, compared with net revenue of $251.0 million for the same period last year.

The modest decline in net revenue from the previous year was primarily due to a reduction in work force, as well as volume mix and a corresponding lower rate per contract, partially offset by the measured expansion of client facilitation and principal risk taking activities.

Net revenue per employee was approximately $86,400 for the third quarter compared with $77,800 for the same period last year. At December 31, 2010 the company had 2,857 employees compared with 3,227 employees at December 31, 2009.

GAAP net loss applicable to common shareholders was $9.7 million or $0.06 per basic and diluted share for the third quarter, compared with net loss applicable to common shareholders of $22.3 million or $0.18 per basic and diluted share for the same period last year.¹

Adjusted earnings per fully diluted share were $0.03 for the third quarter versus $0.01 per fully diluted share for the same period last year. ²

Employee compensation and benefits (excluding severance) during the quarter totaled $136.9 million, or 55.5 percent of net revenue compared with $149.2 million, or 59.4 percent of net revenue in the same period last year. The decrease in compensation and benefits was primarily due to the company’s principal risk taking activities and the restructuring which started in the first quarter.

Non-compensation expense in the third quarter of 2011 was $102.3 million compared with $97.5 million for the same period last year. The increase was primarily due to relocation and rental expense associated with previously leased office space, re-engineering efforts designed to create a more scalable infrastructure and a preliminary legal settlement recorded in the third quarter.

Client payables were $13.1 billion at the end of the quarter, compared with $12.0 billion at March 31, 2010.

“We are using the assets of our firm more effectively than ever before,” said Randy MacDonald, chief financial officer, MF Global. “Our progress is evident on many fronts: enhanced productivity, the resizing of our matched repo book relative to market opportunity, improved leverage ratios, increased client confidence and payables as well as an improving earnings profile. As we look to continue to align our balance sheet and capital structure to support our long-term strategy, we remain focused on extending the permanency of our capital, improving our cash flow and providing the resources necessary to execute our plan.”

Non-GAAP Financial Measures (see also supplementary tables for reconciliation)

In this press release, we provide certain earnings per share ratios based on a fully diluted number of shares (“fully diluted shares”). In accordance with the regulations of the U.S. Securities and Exchange Commission (“SEC”), earnings per share ratios based on fully diluted shares are considered to be non-GAAP financial measures because fully diluted shares represent shares outstanding, as determined on a GAAP basis, with certain adjustments that are made outside of GAAP. We use fully diluted shares for certain ratios for the reasons described further below.

We also provide information related to “adjusted earnings per fully diluted share”, which represents “adjusted earnings” (a non-GAAP financial measure) divided by our fully diluted shares (also a non-GAAP financial measure). “Adjusted earnings” excludes the following items from “Net loss applicable to common shareholders”: Stock compensation expense related to IPO awards; Severance expense; Gains on exchange seats and shares; Impairment of intangible assets and goodwill; Loss on extinguishment of debt; Certain legal settlement costs; Accelerated amortization of debt issuance costs; Foreign currency translation movements; Restructuring charges; Sarbanes Oxley costs; Certain tax adjustments; and Costs associated with the February 2008 broker-related loss. We use “adjusted earnings per fully diluted share” for the same reasons why we present fully diluted share ratios and also because our management believes that the measure provides a more useful metric of our operating performance. In particular, we exclude restructuring charges, a UK bonus tax, stock compensation expense related to IPO awards and costs associated with the February 2008 broker-related loss because we believe that they reflect losses or expenses arising from one-time events that are not reasonably likely to reoccur. In addition, we exclude impairment of intangible assets and goodwill; severance expense; loss on extinguishment of debt; certain litigation settlement expense; accelerated amortization of debt issuance costs; foreign currency translation movements; restructuring charges; gains on exchange seats and shares; Sarbanes Oxley costs; UK bonus tax; and certain tax adjustments because we believe that these gains and losses do not reflect our operating performance and do not help our shareholders understand our past or future financial performance.

The presentation of fully diluted shares and ratios based on fully diluted shares are not intended to be considered in isolation from, as a substitute for or as superior to, the financial information prepared and presented in accordance with GAAP, and our presentation of this measure may be different from non-GAAP financial measures used by other companies.

To determine adjusted earnings per fully diluted share, both the numerator and denominator of the GAAP EPS calculation also require adjustment. For the numerator, interest and amortization of issuance costs on our Convertible Notes, net of tax and dividends on the Series A and Series B Preferred Stock must be added back to net loss applicable to common shareholders. For the denominator, weighted average shares of common stock outstanding is adjusted at December 31, 2010 and 2009 to add back shares underlying restricted stock and stock unit awards (“IPO awards”) granted in connection with our IPO which are not considered dilutive under U.S. GAAP and, therefore, not included in diluted shares of common stock outstanding. These shares are not considered dilutive because, in part, of the value of these awards in relation to the market price of our shares of outstanding common stock. In addition, weighted average shares of common stock outstanding are also adjusted at December 31, 2010 and 2009 to include the impact of our outstanding Series A Preferred Stock, Series B Preferred Stock and Convertible Notes, on an if-converted basis. For the three and nine months ended December 31, 2010 weighted average shares of common stock outstanding is adjusted by 12.0 million, 3.9 million and 18.7 million shares, related to the Series A Preferred Stock, Series B Preferred Stock and Convertible Notes, respectively. For the nine months ended December 31, 2009 weighted

average shares of common stock outstanding is adjusted for 4.9 million, 12.0 million, 14.4 million and 19.6 million shares, related to IPO awards, Series A Preferred Stock, Series B Preferred Stock and Convertible Notes, respectively. For the three months ended December 31, 2009 weighted average shares of common stock outstanding is adjusted for 4.2 million, 12.0 million, 14.4 million and 19.6 million shares, related to IPO awards, Series A Preferred Stock, Series B Preferred Stock and Convertible Notes, respectively. We believe it is meaningful to investors to present ratios based on fully diluted shares because it demonstrates the dilution that investors will experience at the end of the three-year vesting period of our IPO awards and when our Series A Preferred Stock, Series B Preferred Stock and Convertible Notes are converted. It is also how our management internally views dilution.
