Continuing operations generated first quarter 2013 revenues of $285.2 million and pre-tax earnings of $17.9 million

Results from continuing operations included $9.3 million in professional fees related to the announced merger and August 1st technology issue as well as $8.9 million in compensation expenses related to a reduction in workforce

JERSEY CITY, N.J. (May 1, 2013) – Knight Capital Group, Inc. (NYSE Euronext: KCG) today reported a GAAP consolidated loss of $9.4 million, or $0.03 per diluted share, for the first quarter of 2013.

The first quarter 2013 GAAP net loss includes net income from continuing operations of $11.0 million, or $0.03 per diluted share, as well as a net loss from discontinued operations of $20.4 million, or a loss of $0.06 per diluted share. Included in the net income from continuing operations are professional fees related to the announced merger and August 1st technology issue and compensation expenses related to a reduction in workforce. Excluding these expenses, on a non-GAAP basis, the first quarter 2013 net income from continuing operations was $22.3 million, or $0.06 per diluted share. A reconciliation of GAAP to non-GAAP results is included below.

For the first quarter of 2012, the company reported GAAP consolidated earnings of $33.1 million, or $0.36 per diluted share.

Revenues from continuing operations for the first quarter of 2013 were $285.2 million, compared to $302.5 million for the first quarter of 2012.

At March 31, 2013, the company had $439.2 million in cash and cash equivalents. The company had $1.5 billion in stockholders’ equity as of March 31, 2013, equivalent to a book value of $3.96 per share. The company had $1.5 billion in stockholders’ equity as of December 31, 2012, equivalent to a book value of $4.07 per share (which included preferred shares on an as-converted basis). Tangible book value as of March 31, 2013 was $3.25 per share as compared to $3.30 at December 31, 2012 (which included preferred shares on an as-converted basis).

“In the first quarter of 2013, Knight’s teams proved determined and our core competencies resilient,” said Thomas M. Joyce, Chairman and Chief Executive Officer, Knight Capital Group. “Knight’s comeback from the August 1 technology issue remains impressive. During the first quarter, revenues from continuing operations were strong despite a decline in consolidated U.S. equity volume year over year and the lowest quarterly market volatility in more than five years. Knight combined the full service and electronic institutional equities sales teams, announced the sale of institutional fixed income, and merged the Institutional Sales and Trading and Electronic Execution Services reporting segments. At the same time, the firm was engaged in planning for the announced merger with GETCO.”

In the first quarter of 2013, to better reflect the company’s client offering, changes in senior management, the combination of the institutional equities sales teams and how the businesses are managed, the company changed its reporting segments from (i) Market Making, (ii) Institutional Sales and Trading, (iii) Electronic Execution Services, and (iv) Corporate and Other to (i) Market

Making, (ii) Global Execution Services and (iii) Corporate and Other. Market Making consists of all global market making including Knight Link and the company’s activities as a Designated Market Maker at the NYSE. Global Execution Services includes Knight Direct, equity sales and trading, Knight Hotspot FX, Knight BondPoint, futures, reverse mortgage origination and securitization and asset management. Corporate and Other includes strategic investments primarily in financial services-related ventures, clearing and settlement activity, corporate overhead expenses and all other expenses that are not attributable to the other reporting segments.

During the first quarter of 2013, the company agreed to sell institutional fixed income sales and trading to Stifel, Nicolaus & Company, Inc. As a result, these businesses are considered to be held for sale and the results of operations have been reported as discontinued operations. Discontinued operations also include the company’s correspondent clearing business, which the company announced that it was closing in the first quarter of 2013.

Market Making

During the first quarter of 2013, the Market Making segment generated total revenues of $150.7 million and pre-tax income of $36.6 million. In the first quarter of 2012, Market Making reported total revenues of $152.2 million and pre-tax income of $45.1 million. Market Making had pre-tax margins of 24 percent in the first quarter of 2013 compared to pre-tax margins of 30 percent in the first quarter of 2012. The results were impacted by a decrease in our volumes, increases in payments for order flow, as well as the 26% decrease in volatility as measured by the VIX.

“In the Market Making segment, Knight continued to execute,” said Mr. Joyce. “Knight maintained a decisive lead in market share of retail U.S. equity volume, which helped offset a year-over-year decline in retail trading activity. In aggregate, Knight’s average daily U.S. equity dollar value traded and market share of consolidated U.S. equity notional value traded increased slightly compared to a year ago. Nevertheless, financial results were impacted by the subdued volatility and trading expenses.”

Global Execution Services

During the first quarter of 2013, the Global Execution Services segment generated total revenues of $122.4 million and pre-tax income of $10.7 million. In the first quarter of 2012, Global Execution Services generated total revenues of $140.3 million and pre-tax income of $23.8 million. Global Execution Services had pre-tax margins of 9 percent in the first quarter of 2013 compared to pre-tax margins of 17 percent in the first quarter of 2012. The results were impacted by a decline in client volumes as compared to the first quarter of 2012 as well as $4.4 million in additional compensation expense related to workforce reductions associated with the combination of the full service and electronic institutional equities sales teams. These decreases were partially offset by increased earnings from Urban.

“In the Global Execution Services segment, Knight performed well amid the reconfiguring of assets and resources,” said Mr. Joyce. “Knight received diverse contributions from the electronic trading products and sales and trading teams. Urban made a strong contribution from origination and securitization activities. Financial results from continuing operations for the segment, it’s worth noting, included additional expenses primarily related to the consolidation of institutional equities sales.”

Corporate and Other

During the first quarter of 2013, the Corporate and Other segment reported a pre-tax loss of $29.4 million, which included $9.3 million in professional fees related to the announced merger and the August 1st technology issue as well as $4.3 million in additional compensation costs related to the workforce reductions. In the first quarter of 2012, the Corporate and Other segment reported a pre-tax loss of $17.9 million.

“Despite all the activities in the first quarter, Knight’s attention never wavered from our clients,” said Mr. Joyce. “The pending merger with GETCO is continuing on track. Upon the close, the combined firm will enjoy a leading position in the U.S. equities market as well as a decided edge in understanding the potential for all securities markets to better serve participants.”

Headcount at March 31, 2013 was 1,269 full-time employees, which excludes employees affected by the announced sale of institutional fixed income, compared to 1,418 full-time employees at March 31, 2012. The decrease in headcount year over year is primarily due to a reduction in workforce completed during the first quarter.

During the first quarter of 2013, the company did not repurchase any shares under the company’s existing stock repurchase program. To date, the company has repurchased 76.7 million shares for $879.1 million. The company has approximately $120.9 million of availability to repurchase shares under the program. The company cautions that there are no assurances that any further repurchases may actually occur.

Non-GAAP Financial Presentations

The company believes that certain non-GAAP financial presentations, when taken into consideration with the corresponding GAAP financial presentations, are important in understanding the company’s operating results. Selected financial information is included in the company’s non-GAAP financial presentations for the three months ended March 31, 2013. The adjustments incorporate the effects of professional fees related to the announced merger with GETCO and the August 1st technology issue and compensation expenses related to a reduction in workforce. We believe this presentation provides meaningful information to stockholders and investors as it provides comparability for our

results of operations for the three months ended March 31, 2013 with the results for the three months ended March 31, 2012. See schedules below for a full reconciliation of GAAP to non-GAAP financial presentations.
