Torrance, California – May 11, 2006 — PC Mall, Inc. (NASDAQ:MALL - news) today reported Q1 2006 loss per share from continuing operations of $(0.00), which includes a $0.02 per share loss related to stock option expense resulting from our adoption of Financial Accounting Standards Board Statement No. 123 (revised 2004), “Share-Based Payment” (“FAS 123R”) on a modified prospective basis. This compares with Q1 2005 loss per share from continuing operations of $(0.26). During Q1 2006, we incurred a non-cash stock-based compensation expense of $0.5 million, which is included in our selling, general and administrative (“SG&A”) expenses and a related deferred income tax benefit of $0.2 million. Excluding this $0.5 million stock-based compensation expense, pro forma earnings per share from continuing operations for Q1 2006 was $0.02 per share, compared with a loss per share of $(0.26) in Q1 2005.

Consolidated net sales for the quarter were $234.2 million, down two percent from $238.4 million in Q1 2005. Loss from continuing operations in Q1 2006 decreased by $2.9 million compared with Q1 2005, reflecting the results of a number of initiatives we have implemented to increase our gross profit and reduce our SG&A expenses. These initiatives, which include cost reductions and enhancements to account executive productivity, resulted in an increase in total gross profit of $2.7 million, or 134 basis points as a percent of net sales, and a reduction in SG&A expenses of $2.4 million, or 81 basis points as a percent of net sales, (including the $0.5 million of stock-based compensation expense resulting from our adoption of FAS 123R) in Q1 2006 compared with Q1 2005.

Frank Khulusi, Chairman, President and CEO of PC Mall, Inc. said, “We are very pleased with the significant improvement in our results for Q1 2006 from Q1 2005. Despite weak public sector and consumer sales, our Q1 2006 adjusted non-GAAP Core business operating profit margin improved by 173 percent to 90 basis points from a negative 124 basis points in Q1 2005. Our improvement is even more gratifying when considering Apple’s surprise announcement in January 2006 of an accelerated time line for its transition to Intel processors, and its impact on our consumer net sales and related results for the quarter. Despite this challenge, we were able to deliver dramatic year-over-year improvement in our results for Q1 2006 by continuing to execute our strategy of reducing SG&A expenses and improving the productivity of our account executives. Our total SG&A expenses declined by $2.4 million, or 81 basis points as a percent of net sales, from Q1 2005, and we increased the productivity of our commercial account executives in Q1 2006 by 25 percent over Q1 2005.”

In Q1 2006, consolidated net sales decreased by two percent to $234.2 million from $238.4 million in Q1 2005. Core business net sales (excluding net sales of Onsale.com) for Q1 2006 were $229.4 million, down three percent from Q1 2005. Commercial net sales grew five percent, but were offset by a 21 percent decline in consumer net sales and a 17 percent decline in public sector net sales. The decline in consumer net sales was primarily due to Apple’s January 2006 announcement of an accelerated time-line for its transition to Intel processors, and an 18% decrease in consumer advertising expenditures.

Consolidated gross profit in Q1 2006 increased by ten percent, or $2.7 million, to $29.4 million compared to Q1 2005. Consolidated gross profit margin for Q1 2006 increased by 1.4 percent to 12.6 percent compared to 11.2 percent in Q1 2005. Core business gross profit increased by nine percent to $29.1 million in Q1 2006 from Q1 2005.

Consolidated SG&A expenses as a percentage of net sales decreased to 12.2 percent in Q1 2006 from 13.0 percent in Q1 2005. The 0.8 percent decrease in Q1 2006 consolidated SG&A as a percentage of net sales over the prior year quarter was due in part to the 80 basis point decline in personnel costs, a 14 basis point decline in advertising expenditures, a 19 basis point decline in audit and audit related fees, and an eight basis point decline in credit card related fees. These declines in Q1 2006 were partially offset by reductions in costs formerly charged to eCOST.com of 38 basis points and the non-cash stock-based compensation expense of 19 basis points recognized in the first quarter of 2006.

Commercial and public sector account executive headcount included in SG&A at the end of Q1 2006 amounted to 570 employees, down 136 account executives from Q1 2005 and up 11 account executives from Q4 2005. Average tenure for a corporate and public sector account executive at the end of Q1 2006 was 27 months, with nine percent of the commercial and public sector workforce in training, 40 percent with less than one year experience and 60 percent with less than two years experience. Total account executives, including those focused on commercial, public sector and consumer customers, numbered 676 at the end of Q1 2006, down 146 managers from Q1 2005 and down 15 managers from Q4 2005. The reduction in headcount is in line with our previously articulated strategy of focusing on account executive productivity.

We had cash and cash equivalents of $5.0 million at March 31, 2006 compared to $6.3 million at December 31, 2005. Accounts receivable at March 31, 2006 increased by $4.1 million from December 31, 2005 primarily due to increased receivables from our vendors. Inventories of $53.1 million at March 31, 2006 decreased by $11.4 million from December 31, 2005 reflecting seasonality and our sell-through of year-end strategic buys for the holidays. Accounts payable increased by $6.4 million from December 31, 2005 primarily due to timing of payments to our vendors in the current period compared to the 2005 year end. Outstanding borrowings under our line of credit decreased by $11.0 million at March 31, 2006 from December 31, 2005 primarily due to the timing of payments to our vendors and the decrease in our inventories.

Outlook

Khulusi stated, “We are pleased with our accomplishments in Q1 2006 and we believe we are well positioned for the remainder of 2006. Our cost structure is much leaner, and we are continuing our efforts to maximize our Philippines off-shoring initiative to further reduce our costs. We are optimistic regarding the balance of the year, specifically the second half as Apple’s transition to Intel processors continues throughout the year. Our goal remains to achieve a two percent adjusted non-GAAP Core business operating profit margin on a quarterly basis as soon as possible, ideally in the second half of 2006.”

Non-GAAP Measures

As described below, the adjusted non-GAAP Core business operating profit and related operating profit margin contained herein, which are supplemental to the financial results based on generally accepted accounting principles, exclude the results of Onsale.com, net sales to eCOST.com, if any, special charges, non-cash stock-based compensation expenses and SOX-related expenses. Additional items that would be excluded from non-GAAP Core business operating profit and related operating profit margin include restructuring costs and other special items, if any. We believe that the presentation of results excluding these items provides meaningful supplemental information to both management and investors that is indicative of our Core business operating results across reporting periods. We include an income statement reconciliation of these non-GAAP measures to provide a more complete view of their effect on results. We are unable to reconcile our expectations and goals with respect to adjusted non-GAAP quarterly operating profits and margin for the Core business in future periods, because the GAAP financial measures are not accessible on a forward-looking basis.
