Highlights

· Total revenues for the first quarter of 2009 were $216.2 million, and included a $3.2 million mark-to-market unrealized gain on forward hedges of future foreign currency revenues and a $0.7 million gain related to an investment in The Clearing Corporation. Excluding these items, non-GAAP revenues were $212.3 million for the first quarter of 2009. In the first quarter of 2008, total revenues were $314.6 million, on both a GAAP and non-GAAP basis.

· Brokerage revenues for the first quarter of 2009 declined 34% to $197.6 million from $298.2 million in the first quarter of 2008. Revenues in all product categories declined in comparison to the first quarter of 2008, with credit, financial, equity and commodity product revenues down 33%, 40%, 32% and 32%, respectively. Within credit products, revenues from cash fixed income products increased 66% over the first quarter of 2008, while revenues from credit derivative products decreased 66%.

· In the first quarter of 2009, compensation and employee benefits expense was 67.3% of total revenues compared with 61.4% in the first quarter of 2008. On a non-GAAP basis, compensation and employee benefits expense as a percentage of total revenues was 66.7% compared with 61.4% in the first quarter of 2008.

· Non-compensation expense as a percentage of revenues was 24.3% of total revenues in the first quarter of 2009 compared with 20.3% in the first quarter of 2008. On a non-GAAP basis, non-compensation expense as a percentage of revenues was 23.8% for the first quarter of 2009 compared with 19.2% in the first quarter of 2008.

· Net income for the first quarter of 2009 was $11.6 million, or $0.10 per diluted share, compared with $36.0 million, or $0.30 per diluted share, in the first quarter of 2008. On a non-GAAP basis, net income for the first quarter of 2009 was $12.9 million, or $0.11 per diluted share, compared with $38.1 million, or $0.32 in the first quarter of 2008.

Michael Gooch, Chairman and Chief Executive Officer of GFI, commented: “In the first quarter of 2009, we achieved sequential revenue growth in three of our four brokerage product categories, and our cost reduction initiatives contributed to improved profitability. As a result, our net income increased 21% from the fourth quarter of 2008 on a non-GAAP basis, although it was well below the record levels achieved in the first quarter of 2008.

“The contrast between the year-over-year periods was marked. In the first quarter of 2009, the global credit crisis and recessionary environment continued to depress share, index and asset values globally. Additionally, dealers and hedge funds deployed less capital in certain derivative markets

amidst difficult credit conditions and uncertainty about the changing market structure and the effect of proposed government and regulatory action in the U.S. and Europe. The changes in market conditions as well as the adverse impact on our foreign currency denominated revenues of the strengthening U.S. Dollar were significant contributors to the year-over-year revenue decline in each of our product categories.

“Our revenue from credit products were 33% below the first quarter of 2008, but they increased 30% from the fourth quarter of 2008 due to the strong contribution of our cash fixed income brokerage operations. The growth in cash fixed income product revenue partially offset a substantial decline in credit derivative product revenue compared to the first quarter of last year. The decline in credit derivative product revenue was driven by a combination of overall lower market volumes and the defection of a number of our New York credit derivative brokers to a competitor a year ago. We believe that we are seeing signs of renewed confidence and greater certainty in the credit derivative markets that will help lead to the recovery of our trading volumes. Revenues from credit derivatives represented approximately 13% of total revenues for the first quarter of 2009, compared with 26% in the first quarter of 2008.

“Equity product revenues were down 32% year over year and 27% sequentially, primarily because of less liquid markets, generally lower trading volumes in equities and depressed share values in Europe where certain cash equity and equity derivative product commissions are based on notional values.

“Our financial product revenues declined 40% from the first quarter of 2008, while increasing 11% over the fourth quarter of 2008. We are continuing to see dealers scaling back their trading operations in Asia and emerging markets globally. Our revenues were also reduced by the transfer of our global U.S. dollar interest rate swaps business to a third party in March 2008 and the restructuring initiative implemented in the second half of 2008.

“Commodity product revenues decreased 32% from the first quarter of 2008, but rose 9% from the 2008 fourth quarter. A significant reason for the decrease was the substantial decline in the Baltic Dry Freight Index which has adversely impacted our dry freight business in Europe and Asia. However, the index recovered somewhat in the first quarter of 2009 and we believe that our dry freight business has stabilized.

“Employee compensation and benefit expenses, which are the largest component of our costs, decreased 27% from the first quarter of 2008 on a non-GAAP basis, although they increased as a percentage of total revenues, both year-over-year and sequentially. This increase in compensation expense as a percentage of revenues resulted from substantially lower revenues compared to the first quarter of 2008 as well as the continuing impact of the expense we incurred to re-staff our New York credit desks last year and the severance costs related to our front and back office restructuring in the first quarter of 2009. The balance of our expenses decreased 17% from the first quarter of 2008 on a non-GAAP basis but increased as a percentage of revenues year over year, mainly due to the effect of lower revenues. Non-compensation expenses, as a percentage of revenues, improved sequentially over the fourth quarter of 2008, as we continue to focus on controlling costs.

“The evolution of the OTC derivatives markets took a major step forward in the first quarter of 2009 when ICE Trust became the first clearinghouse to process certain credit default swap index transactions. We were an early investor in The Clearing Corporation, which was acquired by IntercontinentalExchange, Inc. in March of 2009, resulting in the formation of ICE Trust, a CDS clearing facility. We continue to have an economic interest in ICE Trust.

“We believe the advent of central clearing for credit derivatives, standardized contract terms and increased electronic trading will help facilitate the recovery of our trading volumes in credit derivative markets.

“Looking at the second quarter of 2009, we currently expect our total revenues to decline by approximately 23% compared to the second quarter of 2008.

“We are intent on making further progress during the remainder of the year by continuing to adapt to changing market dynamics, developing new sources of brokerage commissions and other revenues and controlling direct and indirect costs. We have maintained our strong balance sheet and cash position, and we are pleased to declare a quarterly cash dividend of $0.05 per share again this quarter.”

Revenues

For the first quarter of 2009, total revenues were $216.2 million on a GAAP basis and $212.3 million on a non-GAAP basis. This compares with total revenues of $314.6 million in the first quarter of 2008.

Brokerage revenues in the first quarter of 2009 were $197.6 million, which was 34% below the first quarter of 2008. Revenues in all product categories declined in comparison to the first quarter of 2008, with credit, financial, equity and commodity product revenues down 33%, 40%, 32% and 32%, respectively. Within credit products, a 66% increase in cash fixed income revenues from the first quarter of 2008 partially offset a 66% decrease in credit derivative revenues.

Revenues from trading software, analytics and market data products for the first quarter of 2009 increased 16% to $13.1 million from the same period of 2008 and included a $6.9 million contribution from Trayport Limited, acquired by the Company on January 31, 2008. Trayport’s revenues rose 37% from the first quarter of 2008 in its functional currency, the British Pound Sterling. By geographic region, first quarter 2009 brokerage revenues decreased 38% in EMEA, 25% in the Americas and 49% in Asia-Pacific compared with the first quarter of 2008.

Expenses

For the first quarter of 2009, compensation and employee benefit expense was $145.5 million, a decrease of 25% from the first quarter of 2008. Compensation and employee benefit expense increased as a percentage of total revenues to 67.3% in the first quarter of 2009 from 61.4% in the first quarter of 2008. On a non-GAAP basis, compensation and employee benefit expense decreased 27% to $141.7 million, representing 66.7% of total revenues, compared with 61.4% of total revenues in the first quarter of 2008.

Non-compensation expense for the first quarter of 2009 declined 18% to $52.6 million or 24.3% of total revenues compared with $63.8 million or 20.3% of total revenues in the first quarter of 2008. On a non-GAAP basis, non-compensation expense for the first quarter of 2009 declined 17% to $50.4 million or 23.8% of total revenues compared with $60.5 million or 19.2% of total revenues in the first quarter of 2008.

The effective tax rate for the first quarter of 2009 was 36.0% compared to 37.5% for the same period of 2008.

Earnings

Net income for the first quarter of 2009 was $11.6 million, or $0.10 per diluted share, compared with net income of $36.0 million, or $0.30 per diluted share, in the first quarter of 2008. On a non-GAAP basis, net income for the first quarter of 2009 was $12.9 million, or $0.11 per diluted share, compared with $38.1 million or $0.32 for the first quarter of 2008.

Non-GAAP Financial Measures

To supplement GFI’s unaudited financial statements presented in accordance with GAAP, the Company uses certain non-GAAP measures of financial performance. The presentation of these non-

GAAP financial measures is not intended to be considered in isolation from, as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and may be different from non-GAAP financial measures used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. The non-GAAP financial measures used by GFI include non-GAAP revenues, non-GAAP net income and non-GAAP diluted earnings per share. These non-GAAP financial measures currently exclude amortization of acquired intangibles and certain other items that management views as non-operating or non-recurring from the Company’s statement of income as detailed below.

In addition, GFI may consider whether other significant non-operating or non-recurring items that arise in the future should also be excluded in calculating the non-GAAP financial measures it uses. The non-GAAP financial measures also take into account income tax adjustments with respect to the excluded items.

GFI believes that these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding the Company’s performance by excluding certain items that may not be indicative of the Company’s core business, operating results or future outlook. GFI’s management uses, and believes that investors benefit from referring to these non-GAAP financial measures in assessing the Company’s operating results, as well as when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate comparisons of the Company’s performance to prior periods.

In addition to the reasons stated above, which are generally applicable to each of the items GFI excludes from its non-GAAP financial measures, the Company believes it is appropriate to exclude amortization of acquired intangibles because when analyzing the operating performance of an acquired business, GFI’s management focuses on the total return provided by the investment (i.e., operating profit generated from the acquired entity as compared to the purchase price paid) without taking into consideration any charges for allocations made for accounting purposes. Further, because the purchase price for an acquisition necessarily reflects the accounting value assigned to intangible assets, when analyzing the operating performance of an acquisition in subsequent periods, the Company’s management excludes the GAAP impact of acquired intangible assets on its financial results. GFI believes that such an approach is useful in understanding the long-term return provided by an acquisition and that investors benefit from a supplemental non-GAAP financial measure that excludes the accounting expense associated with acquired intangible assets.

Set forth below is specific detail regarding items excluded in our non-GAAP financial measures. A reconciliation of the non-GAAP to GAAP figures follows this press release.

In the first quarter of 2009, the difference between GAAP and non-GAAP revenue was $3.9 million and the difference between GAAP and non-GAAP net income was $1.3 million and reflected for non-GAAP purposes:

· The exclusion in revenues of:

– a $3.2 million mark-to-market unrealized gain on forward hedges of future foreign currency revenues;

– a $0.7 million gain on the Company’s exchange of its investment in The Clearing Corporation for an investment in a holding company of ICE Trust;

· The exclusion of $1.4 million of amortization on all acquired intangible assets;

· The exclusion of $4.6 million related to severance and other restructuring initiatives, including an $0.8 million charge relating to the termination of a joint venture; and

· The effect of adjusting for these items would increase the Company’s income tax expense by $0.7 million.

In the first quarter of 2008, there was no difference between GAAP and non-GAAP revenues and the difference between GAAP and non-GAAP net income was $2.1 million and reflected for non-GAAP purposes:

· The exclusion of $1.2 million of amortization on all acquired intangible assets.

· The exclusion of items related to the planned relocation of the Company’s New York offices to larger premises in 2008, including:

– $0.8 million of duplicate rent expense;

– $1.4 million of accelerated depreciation expense related to assets to be abandoned; and

· The effect of adjusting for these items would increase the Company’s income tax expense by $1.3 million.
