·                  Net loss for the fourth quarter of 2012 was $11.4 million on a GAAP basis, or a loss of $0.10 per diluted share, compared with a net loss of $22.1 million, or a loss of $0.19 per diluted share, in the fourth quarter of 2011.  On a non-GAAP basis, net loss was $2.9 million, or a loss of $0.02 per diluted share, for the fourth quarter of 2012, compared with a net loss of $7.5 million, or a loss of $0.06 per diluted share, in the fourth quarter of 2011.

·                  Cash earnings for the three month period ended December 31, 2012 were $18.0 million, or $0.16 per diluted share, compared with $12.5 million, or $0.11 per diluted share, for the same period in 2011.

·                  For the year ended December 31, 2012, GAAP net revenues decreased 10.6% to $787.0 million, from $880.8 million in 2011.  Net loss on a GAAP basis for 2012 was $10.0 million, or a loss of $0.09 per diluted share, compared to a net loss of $3.2 million, or a loss of $0.03 per diluted share, in 2011.  On a non-GAAP basis, net revenues for the year ended December 31, 2012 decreased 10.6% to $781.5 million from $874.5 million for 2011.

Michael Gooch, Executive Chairman of GFI, commented: “I am proud to announce the appointment of Colin Heffron as GFI’s next CEO.  In his 25 years with the company, Colin has succeeded in every role and executive capacity he has undertaken.  He has demonstrated extraordinarily leadership as Company President and his appointment as CEO reflects the breadth of his responsibilities at GFI and stature within the industry.  I look forward to continuing to work with Colin in my role as Executive Chairman of the Company.”

“Mr. Gooch further commented “Regulatory, market and economic uncertainty combined with seasonally slow trading resulted in difficult trading conditions in the fourth quarter.   Non-GAAP net revenues and brokerage revenues were down 9.2% and 13.1%, respectively, in the fourth quarter compared to 2011.  However, despite these conditions, GFI’s software, analytics and market data revenues grew 16.6% year over year in the fourth quarter, largely due to growth at Trayport, and GFI moved forward with on-going technology development and cost-reduction initiatives.  We expect to continue to expand our higher-margin, subscription-based Trayport and Fenics software businesses by leveraging their networks and diversifying their product offerings.

“Hurricane Sandy reinforced our belief that proprietary technology provides GFI with a clear competitive advantage.  GFI’s electronic trade matching technology, as well as its disaster recovery sites in New Jersey, enabled our New York area operations to resume business within days of the storm without significant operational disruption. The breadth of GFI’s technology includes significant product and geographical coverage, with electronic trade matching capabilities on approximately 40% of GFI’s desks globally.  Over 60% of GFI’s brokerage revenues, excluding Kyte, are supported by our proprietary trading technology.

“We continued to reduce GFI’s cost base, largely through headcount reductions and by building more flexibility into compensation arrangements over time.  During 2012, we reduced expenses, mainly in the compensation area, by approximately $31 million and are on track to reach over $50 million in total cost savings, over 2011 expense levels, in 2013.  We expect to realize these cost savings relatively equally among the four quarters in 2013, and are encouraged with January’s preliminary results indicating improved profitability compared to last year.

“GFI continues to play an active role in the implementation of swaps market regulatory reform in the U.S., Europe and Asia.  GFI is readying itself to fully serve its global clientele upon completion of the various rulemaking processes.

“Through the second week of February, GFI’s preliminary 2013 total revenues are tracking down approximately 6% compared with total revenues for the same period last year.  We believe that GFI’s revenue performance is within the range of volume or revenue results reported in the broader exchange-traded and OTC derivative markets.

“It is important to note that GFI’s non-GAAP cash EPS was $0.16 per diluted share in the fourth quarter of 2012, up from $0.11 per diluted share in the fourth quarter of 2011, and consistent with the $0.17 per diluted share achieved in the third quarter of 2012.  We also paid the Company’s regular dividend for the fourth quarter of 2012 on an accelerated basis on December 27, 2012.”

Revenues from trading software, analytics and market data products for the fourth quarter of 2012 were $22.5 million, up 16.6% from $19.3 million in the fourth quarter of 2011.

Expenses

For the fourth quarter of 2012, compensation and employee benefits expense was $124.6 million on a GAAP basis and $128.0 million on a non-GAAP basis.  This compares with $161.1 million on a GAAP basis and $138.0 million on a non-GAAP basis in the fourth quarter of 2011. Compensation and employee benefits expense was 71.8% and 73.2% of net revenues on a GAAP and non-GAAP basis, respectively, in the fourth quarter of 2012 compared with 78.7% and 71.6% of net revenues on a GAAP and non-GAAP basis, respectively, in the fourth quarter of 2011.

On a GAAP basis, non-compensation expenses for the fourth quarter of 2012 were $58.3 million, or 33.6% of net revenues, compared with $70.5 million, or 34.5% of net revenues, in the fourth quarter of 2011. On a non-GAAP basis, non-compensation expenses for the fourth quarter of 2012 were $53.3 million, or 30.5% of net revenues, compared with $59.5 million, or 30.9% of net revenues, in the fourth quarter of 2011.

Full Year Results

Net revenues for the year ended December 31, 2012 were $787.0 million on a GAAP basis, compared to net revenues of $880.8 million for the year ended December 31, 2011.  Net loss was $10.0 million on a GAAP basis, or a loss of $0.09 per diluted share, for 2012 compared with a net loss of $3.2 million, or a loss of $0.03 per diluted share, for the same period in 2011.  On a non-GAAP basis, net revenues for the year ended December 31, 2012 were $781.5 million compared to $874.5 million for the same period in 2011.  Non-GAAP net income was $8.9 million, or $0.07 per diluted share, for 2012 compared with non-GAAP net income of $26.5 million, or $0.21 per diluted share, for 2011.

The effective non-GAAP tax rate for 2012 was approximately 11.9%, as compared to 39.0% in 2011.  This was largely driven by a release in the quarter of a tax liability related to prior years.  Excluding this non-recurring tax item, the effective non-GAAP tax rate would have been 33.0% for 2012.

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 total revenues, non-GAAP net revenues, non-GAAP provision for or benefit from income taxes, non-GAAP net income, non-GAAP diluted earnings per share, cash earnings and cash earnings per share. These non-GAAP financial measures currently exclude from the Company’s statement of income amortization of acquired intangibles and certain other items that management views as non-operating, non-recurring or non-cash as detailed in the reconciliation included in the financial tables attached to this release.

In addition, GFI may consider whether other significant non-operating, non-recurring or non-cash 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 estimated adjustments to income tax expense 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

4

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.

A reconciliation of these non-GAAP financial measures to GAAP is included in the financial tables attached to this release.

(1)         As discussed in GFI’s fourth quarter and full year 2012 earnings release, non-GAAP provision for income taxes includes a non-recurring adjustment related to the release of a tax liability related to prior years.  Excluding this item, 2012 non-GAAP provision for income taxes would have been $3,481, resulting in an effective non-GAAP tax rate of approximately 33%.  On a GAAP basis, GFI’s effective tax rate was approximately -667% for 2012 and 3,228% for 2011.
