“We are pleased to report yet another quarter and six-month period of growth in revenues and earnings. We continue to believe, however, that uncertain market conditions, including concerns about Europe and the fate of the European Union, as well as the inability of Washington to address spending and the debt ceiling, may adversely affect investor confidence. While our future results may be negatively impacted as a result of these uncertainties, we remain committed to our strategy of recruiting the finest advisors in the industry,” stated Marshall Leeds, the Company’s Chairman, Chief Executive Officer and President. Mr. Leeds continued, “Fortunately, as a result of the commitment of Summit’s advisors and home office associates, we have been able to report net income for the three- and six- month periods ended June 30, 2013 of $0.79 million and $1.47 million, respectively, compared to $0.47 million and $0.88 million for the respective three- and six- month periods ended June 30, 2012. Additionally, for the three-month periods ended June 30, 2013 and 2012, the Company generated EBITDA, as adjusted, of $1.61 million and $1.04 million, respectively, and $3.25 million and $2.20 million for the respective six-month periods.”

The Company is a Florida-based financial services holding company that provides, through its operating subsidiary, Summit Brokerage Services, Inc. (“Summit Brokerage”), a broad range of securities brokerage and investment services to primarily individual investors. Summit Brokerage also sells insurance products, predominantly fixed and variable annuities and life insurance through its subsidiary, SBS Insurance Agency of Florida. Summit Brokerage also provides asset management services through its investment advisor, Summit Financial Group, Inc.

Summit Brokerage is registered with the Securities and Exchange Commission (SEC), and is a member of FINRA (f/k/a NASD), the Municipal Securities Rule Making Board, and the National Futures Association. The Company currently offers its services through a network of approximately 300 registered representatives, and its business plan is focused primarily on increasing its network of affiliated registered representatives through recruitment as well as by acquisitions.

All of the above numbers have been rounded for ease of presentation.

The following table presents a reconciliation of EBITDA, as adjusted, to net income as reported:

Earnings before interest, taxes, depreciation and amortization, or EBITDA, adjusted for stock-based compensation expense is a key metric the Company uses in evaluating its financial performance. EBITDA is considered a non-GAAP financial measure as defined by Regulation G, promulgated by the SEC under the Securities Act of 1933, as amended. The Company considers EBITDA, as adjusted, important in monitoring and evaluating its financial performance on a consistent basis across various periods, as well as for purposes of, analyzing and evaluating financial and strategic planning decisions regarding future operating investments and potential acquisitions. The Company believes that EBITDA, as adjusted, eliminates items that are not part of its core operations, or do not involve a cash outlay, such as stock-based compensation. EBITDA, as adjusted, should be considered in addition to, rather than as a substitute for, pre-tax income, net income and cash flows from operating activities.
