Filed by Knight Capital Group, Inc.,

Pursuant to Rule 425 under the

Securities Act of 1933, as amended and

deemed filed pursuant to Rule 14a-12

under the Securities Exchange Act of 1934

Subject Companies:

Knight Capital Group, Inc. (Commission File No. 001-14223)

Knight Holdco, Inc. (Commission File No. 333-186624)

The filing, which includes the Joint Press Release issued by Knight Capital Group, Inc. and GETCO Holding Company, LLC on February 20, 2013 may contain certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “target,” “estimate,” “continue,” “positions,” “prospects” or “potential,” by future conditional verbs such as “will,” “would,” “should,” “could” or “may”, or by variations of such words or by similar expressions. These “forward-looking statements” are not historical facts and are based on current expectations, estimates and projections about the parties’ industry, management beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, readers are cautioned that any such forward-looking statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict including, without limitation, risks associated with the August 1, 2012 technology issue at Knight that resulted in Knight sending numerous erroneous orders in NYSE-listed and NYSE Arca securities into the market and the impact to Knight’s capital structure and business as well as actions taken in response thereto and consequences thereof, risks associated with Knight’s ability to recover all or a portion of the damages that are attributable to the manner in which NASDAQ OMX handled the Facebook IPO, risks associated with changes in market structure, legislative, regulatory or financial reporting rules, risks associated with past or future changes to organizational structure and management and the costs, integration, performance and operation of businesses previously acquired or developed organically, or that may be acquired or developed organically in the future. Readers should carefully review the risks and uncertainties disclosed in Knight’s reports with the SEC, including, without limitation, those detailed under “Certain Factors Affecting Results of Operations” and “Risk Factors” in Knight’s Annual Report on Form 10-K for the year-ended December 31, 2011 and in Knight’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2012, and in other reports or documents Knight or KCG files with, or furnishes to, the SEC from time to time and those detailed in the Joint Proxy Statement / Prospectus under the heading “Cautionary Statement Regarding Forward Looking Information” and “Risk Factors”, among others.

In addition to factors previously disclosed in Knight’s reports filed with the SEC and those identified elsewhere in this filing, the following factors among others, could cause actual results to differ materially from forward-looking statements or historical performance: ability to obtain regulatory approvals and meet other closing conditions to the mergers, including approval by Knight and GETCO stockholders, on the expected terms and schedule; delay in closing the

mergers; difficulties and delays in integrating the Knight and GETCO businesses or fully realizing cost savings and other benefits; business disruption following the mergers; the inability to sustain revenue and earnings growth; customer and client actions; and the inability to realize cost savings or revenues or to implement integration plans and other consequences associated with mergers, acquisitions and divestitures.

The following presentation was made to employees on February 20, 2013:

CAUTIONARY STATEMENT REGARDING
FORWARD LOOKING STATEMENTS
CERTAIN STATEMENTS CONTAINED HEREIN MAY CONSTITUTE "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF THE
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995. FORWARD-LOOKING STATEMENTS ARE TYPICALLY IDENTIFIED BY WORDS
SUCH AS “BELIEVE,” “EXPECT,” “ANTICIPATE,” “INTEND,” “TARGET,” “ESTIMATE,” “CONTINUE,” “POSITIONS,” “PROSPECTS” OR
“POTENTIAL,” BY FUTURE CONDITIONAL VERBS SUCH AS “WILL,” “WOULD,” “SHOULD,” “COULD” OR “MAY”, OR BY VARIATIONS
OF SUCH WORDS OR BY SIMILAR EXPRESSIONS. THESE "FORWARD-LOOKING STATEMENTS" ARE NOT HISTORICAL FACTS AND
ARE BASED ON CURRENT EXPECTATIONS, ESTIMATES AND PROJECTIONS ABOUT THE PARTIES’ INDUSTRY, MANAGEMENT
BELIEFS AND CERTAIN ASSUMPTIONS MADE BY MANAGEMENT, MANY OF WHICH, BY THEIR NATURE, ARE INHERENTLY UNCERTAIN
AND BEYOND OUR CONTROL. ACCORDINGLY, READERS ARE CAUTIONED THAT ANY SUCH FORWARD-LOOKING STATEMENTS ARE
NOT GUARANTEES OF FUTURE PERFORMANCE AND ARE SUBJECT TO CERTAIN RISKS, UNCERTAINTIES AND ASSUMPTIONS THAT
ARE DIFFICULT TO PREDICT INCLUDING, WITHOUT LIMITATION, RISKS ASSOCIATED WITH THE AUGUST 1, 2012 TECHNOLOGY ISSUE
AT KNIGHT THAT RESULTED IN KNIGHT SENDING NUMEROUS ERRONEOUS ORDERS IN NYSE-LISTED AND NYSE ARCA SECURITIES
INTO THE MARKET AND THE IMPACT TO KNIGHT'S CAPITAL STRUCTURE AND BUSINESS AS WELL AS ACTIONS TAKEN IN
RESPONSE THERETO AND CONSEQUENCES THEREOF, RISKS ASSOCIATED WITH KNIGHT'S ABILITY TO RECOVER ALL OR A
PORTION OF THE DAMAGES THAT ARE ATTRIBUTABLE TO THE MANNER IN WHICH NASDAQ OMX HANDLED THE FACEBOOK IPO,
RISKS ASSOCIATED WITH CHANGES IN MARKET STRUCTURE, LEGISLATIVE, REGULATORY OR FINANCIAL REPORTING RULES,
RISKS ASSOCIATED WITH PAST OR FUTURE CHANGES TO ORGANIZATIONAL STRUCTURE AND MANAGEMENT AND THE COSTS,
INTEGRATION, PERFORMANCE AND OPERATION OF BUSINESSES PREVIOUSLY ACQUIRED OR DEVELOPED ORGANICALLY, OR
THAT MAY BE ACQUIRED OR DEVELOPED ORGANICALLY IN THE FUTURE. READERS SHOULD CAREFULLY REVIEW THE RISKS AND
UNCERTAINTIES DISCLOSED IN KNIGHT'S REPORTS WITH THE SEC, INCLUDING, WITHOUT LIMITATION, THOSE DETAILED UNDER
"CERTAIN FACTORS AFFECTING RESULTS OF OPERATIONS" AND "RISK FACTORS" IN KNIGHT'S ANNUAL REPORT ON FORM 10-K
FOR THE YEAR-ENDED DECEMBER 31, 2011 AND IN KNIGHT'S QUARTERLY REPORT ON FORM 10-Q FOR THE QUARTER ENDED
SEPTEMBER 30, 2012, AND IN OTHER REPORTS OR DOCUMENTS KNIGHT OR KCG FILES WITH, OR FURNISHES TO, THE SEC FROM
TIME TO TIME AND THOSE DETAILED IN THE JOINT PROXY STATEMENT / PROSPECTUS UNDER THE HEADING “CAUTIONARY
STATEMENT REGARDING FORWARD LOOKING INFORMATION” AND “RISK FACTORS”, AMONG OTHERS.
IN ADDITION TO FACTORS PREVIOUSLY DISCLOSED IN KNIGHT’S REPORTS FILED WITH THE SEC AND THOSE IDENTIFIED
ELSEWHERE IN THIS FILING, THE FOLLOWING FACTORS AMONG OTHERS, COULD CAUSE ACTUAL RESULTS TO DIFFER
MATERIALLY FROM FORWARD-LOOKING STATEMENTS OR HISTORICAL PERFORMANCE: ABILITY TO OBTAIN REGULATORY
APPROVALS AND MEET OTHER CLOSING CONDITIONS TO THE MERGERS, INCLUDING APPROVAL BY KNIGHT AND GETCO
STOCKHOLDERS, ON THE EXPECTED TERMS AND SCHEDULE; DELAY IN CLOSING THE MERGERS; DIFFICULTIES AND DELAYS IN
INTEGRATING THE KNIGHT AND GETCO BUSINESSES OR FULLY REALIZING COST SAVINGS AND OTHER BENEFITS; BUSINESS
DISRUPTION FOLLOWING THE MERGERS; THE INABILITY TO SUSTAIN REVENUE AND EARNINGS GROWTH; CUSTOMER AND CLIENT
ACTIONS; AND THE INABILITY TO REALIZE COST SAVINGS OR REVENUES OR TO IMPLEMENT INTEGRATION PLANS AND OTHER
CONSEQUENCES ASSOCIATED WITH MERGERS, ACQUISITIONS AND DIVESTITURES.
