COMPUTER SOFTWARE INNOVATIONS, INC. ANNOUNCES FOURTH QUARTER AND YEAR END 2010 RESULTS

Easley, SC – (MARKET WIRE) – March 24, 2011 – Computer Software Innovations, Inc. (OTCBB: CSWI), CSI Technology Outfitters(TM) (“CSI”) today announced its financial results for the fourth quarter and full year ended December 31, 2010.

Financial Highlights:

Financial Results – Fourth Quarter 2010:

For the quarter ended December 31, 2010, revenues totaled approximately $11.4 million, a slight increase of 0.2% from the fourth quarter of 2009.

Gross profit for the fourth quarter of 2010 was approximately $2.3 million, a decrease of approximately $0.2 million or 7% from the fourth quarter of 2009, primarily from a decrease in the Cloud Services Segment profits with the increased investment in new product offerings and a decrease in Financial Management Applications new license and services sales, partially offset by an increase in Technology Solutions Segment profits with increased engineering services.

Operating loss for the fourth quarter of 2010 was approximately $36 thousand, a decrease of approximately $0.1 million or 147% from the fourth quarter of 2009, driven by the decrease in gross profit.

CSI posted a net loss of $62 thousand for the fourth quarter of 2010, compared to a net loss of $5 thousand for the fourth quarter of 2009, as a result of the decrease in gross profit. Due to the seasonality of CSI’s business, the fourth and first quarters are traditionally the lowest performing quarters in its fiscal year.

CSI’s EBITDA was approximately $0.6 million for the fourth quarter of 2010, a decrease of approximately $0.1 million or 19% from the fourth quarter of 2009. (EBITDA is a non-GAAP financial measure. See reconciliation to GAAP measure Net Income which follows.)

Financial Results – Fiscal Year 2010:

CSI posted revenues of approximately $52.7 million for the 2010 fiscal year, an increase of $0.9 million or 2% over the 2009 fiscal year. The increase was driven by a $1.2 million or 3% increase in our Technology Solutions Segment and a $0.1 million increase in our Financial Management Applications Segment, partially offset by a $0.4 million or 28% decrease in our Cloud Services Segment.

CSI’s gross profit for the 2010 fiscal year was approximately $10.7 million, a decrease of $0.6 million or 5% below the 2009 fiscal year. This decrease was driven primarily by a decrease in gross profit by the Cloud Services and the Technology Solutions Segments, and partially offset by an increase in gross profit from the Financial Management Applications Segment.

CSI’s operating income for the 2010 fiscal year was approximately $1.1 million, an increase of $0.1 million or 9% over the 2009 fiscal year. The increase was due to the impact of the $0.7 million decrease in operating expenses, partially offset by the $0.6 million decrease in gross profit.

Net income for the 2010 fiscal year was approximately $0.5 million or $0.07 per basic share and $0.03 per diluted share, as compared to net income of approximately $0.3 million, or $0.05 per basic share and $0.02 per diluted share for the 2009 fiscal year.

EBITDA, or earnings before interest, income taxes, depreciation and amortization for the 2010 fiscal year was approximately $3.5 million, a slight increase over the 2009 fiscal year. (EBITDA is a non-GAAP financial measure. See reconciliation to GAAP measure Net Income which follows.)

“I am pleased that CSI was able to hold our own and remain profitable during these trying economic times and that we are in an excellent position to grow our business in the years ahead,” stated Nancy Hedrick, CEO. “During 2010 we launched our Cloud Services Segment, focusing on our CSI@K12 hosted email and hosted voice for the K-12 market. In 2011 we are continuing to

Non-GAAP Financial Measure: Explanation and Reconciliation of EBITDA and Adjusted EBITDA

EBITDA is a non-GAAP financial measure used by management, lenders and certain investors as a supplemental measure in the evaluation of some aspects of a corporation’s financial position and core operating performance. Investors sometimes use EBITDA as it allows for some level of comparability of profitability trends between those businesses differing as to capital structure and capital intensity by removing the impacts of depreciation and amortization. EBITDA also does not include changes in major working capital items such as receivables, inventory and payables, which can also indicate a significant need for, or source of, cash. Since decisions regarding capital investment and financing and changes in working capital components can have a significant impact on cash flow, EBITDA is not a good indicator of a business’s cash flows. We use EBITDA for evaluating the relative underlying performance of the Company’s core operations and for planning purposes, including a review of this indicator and discussion of potential targets in the preparation of annual operating budgets. We calculate EBITDA by adjusting net income or loss to exclude net interest expense, income tax expense or benefit, depreciation and amortization, thus the term “Earnings Before Interest, Taxes, Depreciation and Amortization” and the acronym “EBITDA.”

EBITDA is presented as additional information because management believes it to be a useful supplemental analytic measure of financial performance of our core business, and as it is frequently requested by sophisticated investors. However, management recognizes it is no substitute for GAAP measures and should not be relied upon as an indicator of financial performance separate from GAAP measures (as discussed further below).

“Adjusted EBITDA or “Financing EBITDA” is a non-GAAP financial measure used in our calculation and determination of compliance with debt covenants related to our bank credit facilities. Adjusted EBITDA is also used as a representation as to how EBITDA might be adjusted by potential lenders for financing decisions and our ability to service debt. However, such decisions would not exclude those other items impacting cash flow which are excluded from EBITDA, as noted above. Adjusted EBITDA is defined as net income or loss adjusted for net interest expense, income tax expense or benefit, depreciation, amortization, and also certain additional items allowed to be excluded from our debt covenant calculation including other non-cash items such as operating non-cash compensation expense (such as stock-based compensation), and the Company’s initial reorganization or restructuring related costs, unrealized gain or loss on financial instrument (non-cash related) and gain or loss on the disposal of fixed assets. While we evaluate the Company’s performance against debt covenants on this basis, investors should not presume the excluded items to be one-time costs. If the Company were to enter into additional capital transactions, for example, in connection with a significant acquisition or merger, similar costs could reoccur. In addition, the ongoing impact of those costs would be considered in, and potential financings based on, projections of future operating performance which would include the impact of financing such costs.

We believe the presentation of Adjusted EBITDA is important as an indicator of our ability to obtain additional financing for the business, not only for working capital purposes, but particularly as acquisitions are anticipated as a part of our growth strategy. Accordingly, a significant part of our success may rely on our ability to finance acquisitions.

When evaluating EBITDA and Adjusted EBITDA, investors should consider, among other things, increasing and decreasing trends in both measures and how they compare to levels of debt and interest expense, ongoing investing activities, other financing activities and changes in working capital needs. Moreover, these measures should not be construed as alternatives to net income (as an indicator of operating performance) or cash flows (as a measure of liquidity) as determined in accordance with GAAP.

While some investors use EBITDA to compare between companies with different investment and capital structures, all companies do not calculate EBITDA or Adjusted EBITDA in the same manner. Accordingly, the EBITDA and Adjusted EBITDA measures presented below may not be comparable to similarly titled measures of other companies.
