“With volatility measures globally at historic lows, challenging conditions for market makers persisted in the second quarter.  We continue to be disciplined in our approach to market making and vigilant around costs to support our results.  On July 20, we closed the acquisition of KCG.  Based on what has been accomplished to date and the positive feedback from our clients, we remain more confident than ever in the value creation potential of the acquisition.  KCG has long-standing and deep client relationships in market making and global agency execution services.  We believe the combination of this client franchise and Virtu’s technology and market structure acumen will benefit the combined company in any environment and will enhance our business and financial results.  We have already made material progress toward integration and synergy realization.  Of the $250 million in gross synergies projected at the time of the transaction announcement, we have already taken actions to realize at least $125 million of annual run rate savings by the end of the third quarter for 2017 as we make the combined firm more efficient and focused.  We are well on our way to meeting or exceeding our synergy goals and are optimistic about the trading efficiencies,” said Douglas Cifu, Chief Executive Officer of Virtu Financial.

Business Performance

Since our inception, we have sought to broadly diversify our market making across securities, asset classes and geographies, and as a result, for the quarter ended June 30, 2017, we achieved a diverse mix of Adjusted Net Trading Income results, with no one category constituting more than 33.4% of our total Adjusted Net Trading Income. Average daily Adjusted Net Trading Income was approximately $1.175 million for this quarter compared to $1.599 million for the same period in the previous year.

As of June 30, 2017, Virtu was connected to more than 235 unique market venues in 36 countries and made markets in over 12,000 financial instruments.

The following tables show our trading income, net; average daily trading income, net; and percentage of trading income, net by category for the three and six months ended June 30, 2017 and 2016, respectively.

(1) Under our methodology for recording ‘‘trading income, net’’ in our condensed consolidated statements of comprehensive income, we recognize revenues based on the exit price of assets in accordance with applicable U.S. GAAP rules, and when we calculate Adjusted Net Trading Income for corresponding reporting periods, we start with trading income, net. By contrast, when we calculate Adjusted Net Trading Income by category, we recognize revenues on a daily basis, and as a result prices used in recognizing revenues may differ. Because we provide liquidity on a global basis, across asset classes and time zones, the timing of any particular Adjusted Net Trading Income calculation can defer or accelerate the amount in a particular asset class from one day to another, and, at the end of a reporting period, from one reporting period to another. The purpose of the Unallocated category is to ensure that ANTI by category sums to total Adjusted Net Trading Income, which can be reconciled to Trading Income, Net, calculated in accordance with GAAP. We do not allocate any resulting differences based on the timing of revenue recognition.

Non-GAAP Financial Measures and Other Items

To supplement our unaudited condensed consolidated financial statements presented in accordance with generally accepted accounting principles (“GAAP”), we use the following non-GAAP measures of financial performance:

·                  “Adjusted Net Trading Income”, which is the amount of revenue we generate from our market making activities, or trading income, net, plus interest and dividends income and expense, net, less direct costs associated with those revenues, including brokerage, exchange and clearance fees, net. Management believes that this measurement is useful for comparing general operating performance from period to period. Although we use Adjusted Net Trading Income as a financial measure to assess the performance of our business, the use of Adjusted Net Trading Income is limited because it does not include certain material costs that are necessary to operate our business. Our presentation of Adjusted Net Trading Income should not be construed as an indication that our future results will be unaffected by revenues or expenses that are not directly associated with our market making activities.

·                  “EBITDA”, which measures our operating performance by adjusting Net Income to exclude financing interest expense on our senior secured credit facility, debt issue cost related to debt refinancing, depreciation and amortization, amortization of purchased intangibles and acquired capitalized software, and income tax expense, and “Adjusted EBITDA”, which measures our operating performance by further adjusting EBITDA to exclude severance, reserve for legal matter, transaction advisory fees and expenses, termination of office leases, other losses (revenues) net, equipment write-off, share based compensation, charges related to share based compensation at IPO, 2015 Management Incentive Plan, and charges related to share based compensation at IPO.

·                  “Normalized Adjusted Net Income”, “Normalized Adjusted Net Income before income taxes”, “Normalized provision for income taxes”, and “Normalized Adjusted EPS”, which we calculate by adjusting Net Income to exclude certain items including IPO-related adjustments and other non-cash items, assuming that all vested and unvested Virtu Financial LLC units have been exchanged for Class A Common Stock, and applying a corporate tax rate of 35.5%.

Total Adjusted Net Trading Income, EBITDA, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS are non-GAAP financial measures used by management in evaluating operating performance and in making strategic decisions. Additional information provided regarding the breakdown of Total Adjusted Net Trading Income by category is also a non-GAAP financial measure but is not used by the Company in evaluating operating performance and in making strategic decisions. In addition, these non-GAAP financial measures or similar non-GAAP measures are used by research analysts, investment bankers and lenders to assess our operating performance. Management believes that the presentation of Adjusted Net Trading Income, EBITDA, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS provide useful information to investors regarding our results of operations because they assist both investors and management in analyzing and benchmarking the performance and value of our business. Adjusted Net Trading Income, EBITDA, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS provide indicators of general economic performance that are not affected by fluctuations in certain costs or other items. Accordingly, management believes that these measurements are useful for comparing general operating performance from period to period. Furthermore, our credit agreement contains covenants and other tests based on metrics similar to Adjusted EBITDA. Other companies may define Adjusted Net Trading Income, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS differently, and as a result our measures of Adjusted Net Trading Income, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS may not be directly comparable to those of other companies. Although we use these non-GAAP financial measures

as financial measures to assess the performance of our business, such use is limited because they do not include certain material costs necessary to operate our business.

Adjusted Net Trading Income, EBITDA, Adjusted EBITDA and Normalized Adjusted Net Income should be considered in addition to, and not as a substitute for, Net Income in accordance with U.S. GAAP as a measure of performance. Our presentation of Adjusted Net Trading Income, EBITDA, Adjusted EBITDA, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes and Normalized Adjusted EPS should not be construed as an indication that our future results will be unaffected by unusual or nonrecurring items. Adjusted Net Trading Income, Normalized Adjusted Net Income, Normalized Adjusted Net Income before income taxes, Normalized provision for income taxes, Normalized Adjusted EPS and our EBITDA-based measures have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

·                  they do not reflect every cash expenditure, future requirements for capital expenditures or contractual commitments;

·                  our EBITDA-based measures do not reflect the significant interest expense or the cash requirements necessary to service interest or principal payment on our debt;

·                  although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced or require improvements in the future, and our EBITDA-based measures do not reflect any cash requirement for such replacements or improvements;

·                  they are not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows;

·                  they do not reflect the impact of earnings or charges resulting from matters we consider not to be indicative of our ongoing operations; and

·                  they do not reflect limitations on our costs related to transferring earnings from our subsidiaries to us.

Because of these limitations, Adjusted Net Trading Income, EBITDA, Adjusted EBITDA and Normalized Adjusted Net Income are not intended as alternatives to Net Income as indicators of our operating performance and should not be considered as measures of discretionary cash available to us to invest in the growth of our business or as measures of cash that will be available to us to meet our obligations. We compensate for these limitations by using Adjusted Net Trading Income, EBITDA, Adjusted EBITDA and Normalized Adjusted Net Income along with other comparative tools, together with U.S. GAAP measurements, to assist in the evaluation of operating performance. These U.S. GAAP measurements include Net Income (loss), cash flows from operations and cash flow data. See below a reconciliation of each non-GAAP measure to the most directly comparable GAAP measure.
