El Segundo, California — August 7, 2012 — PC Mall, Inc. (NASDAQ:MALL), a leading IT solutions provider, today reported financial results for the second quarter of 2012. Consolidated net sales for Q2 2012 were a second quarter record $362.6 million, an increase of $0.7 million, from $361.9 million in Q2 2011, and was impacted by a $16.7 million decrease in sales to promotional companies under a vendor program change in Q4 by a large vendor. Excluding the effect of this program change, our sales grew $17.4 million, or 5% compared to Q2 2011. Consolidated gross profit for Q2 2012 increased 5% to a second quarter record $48.5 million from $46.4 million in Q2 2011. Consolidated gross profit margin was 13.4% in Q2 2012 compared to 12.8% in Q2 2011. EBITDA (as defined below), which includes $0.5 million of severance and restructuring related costs for Q2 2012, increased $1.6 million to $6.6 million from $5.0 million in Q2 2011. Consolidated operating profit for Q2 2012, which includes $0.7 million of severance and restructuring related costs, increased 33% to $3.4 million compared to $2.6 million for Q2 2011. Consolidated net income for Q2 2012 was $1.4 million compared to $1.0 million for Q2 2011. Diluted EPS for Q2 2012 was $0.12 compared to diluted EPS of $0.08 for Q2 2011.

Commenting on the Company’s second quarter results, Frank Khulusi, Chairman, President and CEO of PC Mall, Inc. said, “We are pleased that, despite an uncertain macro environment, we were able to grow our sales by 5% year over year in Q2 excluding the vendor program change, while increasing our gross margin to 13.4%. We continue to be focused on our operating expenses, and through disciplined cost controls we were able to grow our EBITDA by 31% and our diluted EPS by 50% year over year. Included in EBITDA are $0.5 million of severance and restructuring related costs and, excluding those costs, our EBITDA would have been $7.1 million in Q2. Our focus on our services business is paying off, as evidenced by strong services growth in the first half of 2012 of 27%. We are also excited about the pending changes associated with our rebranding, which we expect to be effected on January 1, 2013. We look forward to sharing more information and details regarding our rebranding strategies in the weeks to come.”

Khulusi continued, “While we are cautiously optimistic about the demand environment in the 2nd half of 2012, based upon the demand trends we saw in the second quarter and macro-economic uncertainty, our current financial goals for this year are to achieve revenue of at least $1.5 billion and EBITDA, excluding severance and restructuring related expenses, of between $29 million and $31 million. We continue to take steps to improve our gross margins, including making significant investments in our services businesses, which, in addition to many cost control measures, are making meaningful contributions to our bottom line. We believe we are well positioned in the marketplace and well situated for the future, and as we consummate our rebranding, our IT systems upgrade and integration and make additional planned improvements, we expect these changes will have a positive and material effect on our results.”

Segment Results

SMB

Q2 2012 net sales for our SMB segment were $115.6 million compared to $131.3 million in Q2 2011, a decrease of $15.7 million, or 12%. This decrease was due to a $17.2 million decline in sales to promotional companies as a result of the program change mentioned earlier, offset by a $1.6 million increase in sales to customers outside that program. As we indicated previously, the effects of this program change will continue to have an impact on year over year comparisons throughout 2012. In 2011, sales under this program were approximately $23.2 million, $20.0 million, $12.7 million and $8.8 million in Q1, Q2, Q3 and Q4 respectively.

Q2 2012 SMB gross profit remained flat at $16.8 million in Q2 2012 and Q2 2011. SMB gross profit margin increased to 14.5% in Q2 2012 compared to 12.8% in Q2 2011 primarily due to an increase in vendor consideration as a percentage of net sales as well as a decrease in sales to promotional companies at lower margins.

Q2 2012 SMB operating profit increased by $0.6 million, or 7%, to $9.6 million compared to $9.0 million in Q2 2011. This increase resulted primarily from small improvements in a number of components of selling, general and administrative expenses.

MME

Q2 2012 net sales for our MME segment were $149.0 million compared to $128.6 million in Q2 2011, an increase of $20.4 million, or 16%. This increase was primarily due to a 14% increase in net sales of products in Q2 2012 compared to Q2 2011, as well as a 26% increase in sales of services. In Q2 2012, sales of services increased to 20% of MME segment sales from 18% of sales in Q2 2011.

MME gross profit increased by $1.9 million, or 10%, to $21.8 million in Q2 2012 compared to $19.9 million in Q2 2011, and MME gross profit margin decreased to 14.6% in Q2 2012 compared to 15.4% in Q2 2011. The increase in MME gross profit was due to the increased MME net sales discussed above, partially offset by a decrease in product margins. The decrease in MME gross profit margin was primarily due to a 50 basis point decrease in vendor consideration as a percentage of sales and a competitive pricing environment for product sales.

MME operating profit in Q2 2012 increased by $0.5 million, or 6%, to $8.2 million compared to $7.7 million in Q2 2011. The increase was primarily due to the increased MME gross profit discussed above, partially offset by a $0.6 million increase in personnel costs and a $0.3 million increase in depreciation and amortization expenses primarily related to the acceleration of our SARCOM and NSPI trademark amortization in connection with our rebranding strategy. The increase in personnel costs was primarily related to an increase in unutilized service labor and variable compensation costs related to the growth in our business and a $0.2 million increase in employee severance costs. Q2 2012 operating profit also included a $0.2 million benefit from a decrease in the estimated fair value of the contingent consideration liability related to our NSPI acquisition, compared to a $0.8 million benefit recorded in Q2 2011.

Public Sector

Q2 2012 net sales for our Public Sector segment were $41.6 million compared to $41.4 million in Q2 2011, an increase of $0.2 million, or 1%. This increase in Public Sector net sales was due to a 19% increase in sales to state and local government and educational institutions (SLED) resulting primarily from increased account executive headcount focused on SLED business and increased account executive productivity, partially offset by a 26% decrease in our federal government business.

Public Sector gross profit increased by $0.3 million, or 10%, to $3.7 million in Q2 2012 compared to $3.4 million in Q2 2011. Public Sector gross profit margin increased to 8.8% in Q2 2012 compared to 8.1% in Q2 2011. The increase in Public Sector gross profit and gross profit margin was primarily due to an increase in selling margin and an increase in vendor consideration.

Public Sector operating loss decreased by $0.1 million, or 30%, to $0.2 million in Q2 2012 compared to $0.3 million in Q2 2011. The decrease in Public Sector operating loss was primarily due to the increase in Public Sector gross profit discussed above, partially offset by a $0.4 million increase in personnel costs.

MacMall/OnSale

Q2 2012 net sales for our MacMall/OnSale segment were $56.3 million compared to $61.1 million in Q2 2011, a decrease of $4.7 million, or 8%. The decrease in MacMall/OnSale net sales was primarily due to what we believe was a combination of soft demand in anticipation of product releases as well as constrained inventory once those products were announced.

MacMall/OnSale gross profit remained flat at $6.3 million in Q2 2012 and Q2 2011. MacMall/OnSale gross profit margin increased to 11.2% in Q2 2012 compared to 10.3% in Q2 2011. The increase in MacMall/OnSale gross profit margin was primarily due to an increase in selling margin as well as a 28 basis point increase in vendor consideration as a percentage of sales.

MacMall/OnSale operating profit increased by $1.0 million to $0.8 million in Q2 2012 compared to an operating loss of $0.2 million in Q2 2011. This increase in MacMall/OnSale operating profit was primarily due to a decrease in third party support costs of $0.3 million which were incurred in the prior year to transition our eCost acquisition, a decrease in personnel costs of $0.2 million, a decrease in legal costs of $0.2 million and a decrease in credit card related costs of $0.2 million.

Corporate & Other

Corporate & Other operating expenses includes corporate related expenses such as legal, accounting, information technology, product management and certain professional and pre-sales support services and other administrative costs that are not otherwise included in our reportable operating segments. Q2 2012 Corporate & Other operating expenses increased by $1.2 million, or 9%, to $14.8 million from $13.6 million in Q2 2011. The increase in Q2 2012 was primarily related to a $1.1 million increase in personnel costs primarily supporting continued investments in IT and professional and pre-sales support services, and a $0.4 million increase in depreciation expense associated with the completed portions of our on-going systems upgrades, partially offset by a $0.5 million decrease in litigation costs.

Consolidated Balance Sheet

Accounts receivable at June 30, 2012 was $195.3 million and decreased by $12.7 million from December 31, 2011. Inventory at June 30, 2012 was $76.4 million and decreased $3.0 million from December 31, 2011, primarily reflecting a sell-through of seasonal purchases made in late 2011, but includes new opportunistic purchases made near the end of Q2 2012. Accounts payable at June 30, 2012 was $128.4 million and increased by $5.8 million from December 31, 2011. Capital expenditures during the six months ended June 30, 2012 were $5.1 million compared to capital expenditures of $14.8 million during the six months ended June 30, 2011, with the decrease primarily due to the purchase in Q1 2011 of our new headquarters building for $9.6 million. Outstanding borrowings under our line of credit decreased by $20.1 million to $71.8 million at June 30, 2012 compared to December 31, 2011. Working capital increased by $7.6 million as of June 30, 2012 compared to December 31, 2011.

Non-GAAP Measure

We are presenting earnings before interest, taxes, depreciation and amortization expenses (EBITDA), which is a financial measure that is not determined in accordance with accounting principles generally accepted in the United States of America, or GAAP. EBITDA should be used in conjunction with other GAAP financial measures and is not presented as an alternative measure of operating results, as determined in accordance with GAAP. We believe that this non-GAAP financial measure allows a more meaningful comparison of our operating performance trends to both management and investors that is more indicative of our consolidated operating results across reporting periods. Depreciation and amortization expenses primarily represent an allocation to current expense of the cost of historical capital expenditures and for acquired intangible assets resulting from prior business acquisitions. A reconciliation of the non-GAAP consolidated financial measure is included in a table below.
