Certain statements in this press release, including those describing the completion of the redemption, constitute forward-looking statements. These statements are not historical facts but instead represent only KCG's belief regarding future events, many of which, by their nature, are inherently uncertain and outside KCG's control. It is possible that actual results will differ, possibly materially, from the anticipated results indicated in these statements. Factors that could cause actual results to differ, possibly materially, from those in the forward-looking statements are discussed throughout KCG's periodic filings with the SEC pursuant to the Securities Exchange Act of 1934.

Certain statements contained herein constitute "forward-looking statements" within the meaning of the safe harbor provisions of the U.S. 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 similar expressions. These "forward looking statements" are not historical facts and are based on current expectations, estimates and projections about KCG's industry, management's beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Any forward-looking statement contained herein speaks only as of the date on which it is made. 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: (i) the inability to manage trading strategy performance and grow revenue and earnings; (ii) the receipt of additional payments from the sale of KCG Hotspot that are subject to certain contingencies; (iii) changes in market structure, legislative, regulatory or financial reporting rules, including the increased focus by Congress, federal and state regulators, self-regulatory organizations and the media on market structure issues, and in particular, the scrutiny of high frequency trading, best execution, internalization, alternative trading systems, market fragmentation, colocation, access to market data feeds, and remuneration arrangements such as payment for order flow and exchange fee structures; (iv) past or future changes to KCG's organizational structure and management; (v) KCG's ability to develop competitive new products and services in a timely manner and the acceptance of such products and services by KCG's customers and potential customers; (vi) KCG's ability to keep up with technological changes; (vii) KCG's ability to effectively identify and manage market risk, operational and technology risk, cybersecurity risk, legal risk, liquidity risk, reputational risk, counterparty and credit risk, international risk, regulatory risk, and compliance risk; (viii) the cost and other effects of material contingencies, including litigation contingencies, and any adverse judicial, administrative or arbitral rulings or proceedings; (ix) the effects of increased competition and KCG's ability to maintain and expand market share; (x) the migration of KCG's Jersey City, NJ data center operations to other commercial data centers and colocations; (xi) the completion of the Merger in a timely manner or at all; (xii) obtaining required governmental approvals of the Merger on the terms expected or on the anticipated schedule; (xiii) KCG's stockholders failing to approve the Merger; (xiv) the parties to the Merger Agreement failing to satisfy other conditions to the completion of the Merger, or failing to meet expectations regarding the timing and completion of the Merger; the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement; (xv) the effect of the announcement or pendency of the Merger on KCG s business relationships, operating results, and business generally; (xvI) risks that the proposed Merger disrupts current operations of KCG and potential difficulties in KCG employee retention as a result of the Merger; risks related to diverting management's attention from KCG s ongoing business operations; (xvii) the outcome of any legal proceedings that may be instituted against KCG related to the Merger Agreement or the Merger; and (xvIii) the amount of the costs, fees, expenses and other charges related to the Merger. The list above is not exhaustive. Because forward looking statements involve risks and uncertainties, the actual results and performance of KCG may materially differ from the results expressed or implied by such statements. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Unless otherwise required by law, KCG also disclaims any obligation to update its view of any such risks or uncertainties or to announce publicly the result of any revisions to the forward-looking statements made herein. Readers should carefully review the risks and uncertainties disclosed in KCG's reports with the SEC, including those detailed in "Risk Factors" in Part I, Item 1A and elsewhere in the Annual Report on Form 10-K, Quarterly Report on Form 10-Q for the quarter ended March 31, 2017, and in other reports or documents KCG files with, or furnishes to, the SEC from time to time.
