Torrance, California – November 6, 2006 — PC Mall, Inc. (NASDAQ:MALL - news) today reported Q3 2006 earnings per share of $0.15, which includes the dilutive impact of $0.02 per share related to stock-based compensation expense resulting from our adoption of Financial Accounting Standards Board Statement No. 123 (revised 2004), “Share-Based Payment” (“FAS 123R”). This compares with Q3 2005 earnings per share of $0.02. During Q3 2006, we incurred a pre-tax non-cash stock-based compensation expense of $0.4 million, which is included in our selling, general and administrative (“SG&A”) expenses, and a related deferred income tax benefit of $0.1 million.

Consolidated net sales for Q3 2006 was $242.2 million, an increase of $8.7 million from non-GAAP consolidated net sales of $233.5 million in Q3 2005, excluding net sales in Q3 2005 of $10.6 million to our former subsidiary, eCOST.com, generally at our cost. These sales to our former subsidiary were made under product sales and consignment agreements entered into during the post-spin transition period. Such product sales and consignment agreements terminated pursuant to their terms in Q3 2005. Consolidated net sales of $242.2 million for Q3 2006 decreased by $1.8 million compared to consolidated net sales (including sales to eCOST.com) of $244.0 million in Q3 2005.

Net income in Q3 2006 was $1.9 million, an increase of $1.7 million compared with net income of $0.2 million in Q3 2005. This increase reflects the result of a number of initiatives we have implemented to increase our gross profit, increase our vendor consideration and reduce our SG&A expenses. These initiatives, as well as our acquisition of GMRI’s products business in September 2006, resulted in an increase in total gross profit of $2.1 million. Total gross profit margin increased to 13.0 percent of net sales in Q3 2006 compared to 12.1 percent of net sales in Q3 2005. Excluding the impact of the sales to eCOST.com in the prior year generally at our cost, non-GAAP total gross profit margin was 12.6 percent in Q3 2005. The increase was primarily due to a 66 basis point increase in vendor consideration in Q3 2006 as a percent of net sales. In Q3 2006, our SG&A expenses declined $0.7 million, a decline of 19 basis points as a percent of net sales compared to Q3 2005. On a non-GAAP basis, excluding the net sales to eCOST.com in Q3 2005, SG&A expenses as a percent of net sales declined by 72 basis points.

Frank Khulusi, Chairman, President and CEO of PC Mall, Inc. said, “We set a new third quarter record for profits in Q3 2006 and essentially hit our goal of a two percent adjusted non-GAAP Core business operating profit margin in the current quarter, one quarter ahead of schedule. We also set a new third quarter record for sales in Q3 2006, excluding last year’s sales to eCOST.com. Q3 2006 was also the first quarter where the bulk of our off-shoring and other labor savings were in place for most of the quarter. Excluding the additional costs of stock-based compensation and GMRI, our labor expenses in Q3 2006 were reduced by $1.4 million from Q3 2005. Our Q3 2006 adjusted non-GAAP Core business operating profit margin more than doubled to 1.97 percent from 0.84 percent in Q3 2005. Going forward, we will maintain our focus on profitability. While we expect that there will be quarterly fluctuations in our adjusted non-GAAP quarterly operating profit margin in part as a result of probable fluctuations in sales and the various components of gross margin, we are very pleased with our overall trend line.”

In Q3 2006, consolidated net sales were $242.2 million compared to $244.0 million in Q3 2005, a decrease of $1.8 million. This decrease was due to the $10.6 million of net sales in Q3 2005, generally at our cost, to eCOST.com, which we spun-off in April 2005, as discussed above. Excluding the net sales to eCOST.com in Q3 2005, our Q3 2006 consolidated net sales increased by $8.7 million to $242.2 million from non-GAAP consolidated net sales of $233.5 million in Q3 2005. Core business (which excludes OnSale.com) net sales for Q3 2006 were $239.9 million compared with $232.4 million in Q3 2005, excluding the net sales to eCOST.com, an increase of three percent. Commercial net sales grew eight percent in Q3 2006 compared to Q3 2005, primarily the result of an 11 percent increase in SMB sales. Public sector sales increased four percent, primarily due to the $7.6 million of net sales resulting from the products business acquired from GMRI in September 2006. These increases in Core business net sales were offset by a ten percent decline in consumer net sales. This ten percent decrease is an improvement from the 21 percent decreases experienced in the first and second quarters of 2006 compared to the same periods in 2005. This improvement resulted in part from a reduced negative impact on our consumer net sales of Apple’s transition to Intel processors, which was completed in August 2006.

Consolidated gross profit in Q3 2006 increased by $2.1 million, or 7%, to $31.6 million. Consolidated gross profit margin for Q3 2006 increased by 0.9 percent to 13.0 percent compared to 12.1 percent in Q3 2005. Excluding the $10.6 million of net sales to eCOST.com in Q3 2005, generally at our cost, consolidated gross profit margin for Q3 2006 increased by 0.4 percent compared to non-GAAP consolidated gross profit margin of 12.6 percent in Q3 2005.

Consolidated SG&A expenses as a percent of net sales was 11.3 percent in Q3 2006 compared to 11.5 percent in Q3 2005, a decrease of 20 basis points. Excluding the $10.6 million of net sales to eCOST.com in Q3 2005, consolidated SG&A expenses as a percent of net sales decreased 80 basis points in Q3 2006 from non-GAAP SG&A expenses as a percent of net sales of 12.1 percent in Q3 2005. The 80 basis point decrease in Q3 2006 consolidated SG&A as a percent of net sales over the prior year quarter was due primarily to the 71 basis point decline in personnel costs and a 42 basis point decline in advertising expenditures, partially offset by a 19 basis point increase in legal fees and the non-cash stock-based compensation expense of 15 basis points recognized in the third quarter of 2006. The $10.6 million of net sales to eCOST.com had a negative impact of 52 basis points on SG&A as a percent of net sales in Q3 2006 compared to Q3 2005.

Commercial and public sector account executive headcount included in SG&A at the end of Q3 2006 amounted to 606 employees, up 41 account executives from Q3 2005 and up 40 account executives from Q2 2006. Average tenure for a corporate and public sector account executive, excluding the GMRI business, at the end of Q3 2006 was 27 months, with 14 percent of the commercial and public sector workforce in training, 38 percent with less than one year experience and 57 percent with less than two years experience. Total account executives, including those focused on commercial, public sector and consumer customers, numbered 703 at the end of Q3 2006, up 31 managers from Q3 2005, and up 1 manager from Q2 2006. The increase of 31 account executives in Q3 2006 from Q3 2005 includes the addition of 17 account executives from the acquisition of GMRI’s products business.

We had cash and cash equivalents of $6.9 million at September 30, 2006 compared to $6.3 million at December 31, 2005. Accounts receivable at September 30, 2006 increased by $13.7 million from December 31, 2005. Inventories of $40.0 million at September 30, 2006 decreased by $24.5 million from December 31, 2005 reflecting our efforts to optimize inventory levels, seasonality and our sell-through of year-end strategic buys for the holidays from the prior year end. Accounts payable increased by $14.8 million from December 31, 2005. Outstanding borrowings under our line of credit decreased by $29.7 million at September 30, 2006 from December 31, 2005.

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.

In addition, we are presenting certain other consolidated non-GAAP financial measures, which exclude sales to eCOST.com, generally at our cost under product sales and consignment agreements entered into during the post-spin transition period. Such product sales and consignment agreements terminated pursuant to their terms in Q3 2005. We believe the exclusion of such sales from the prior year results allows a more meaningful comparison of our sales, gross profit margin and SG&A trends to both management and investors that is indicative of our consolidated operating results across reporting periods because such sales resulted solely as a result of our transition of eCOST.com, and are not expected to reoccur. We indicate the use of these non-GAAP financial measures within the discussions of consolidated net sales, gross profit margin and SG&A.
