Torrance, California — August 5, 2010 — PC Mall, Inc. (NASDAQ:MALL), a leading IT solutions provider, today reported financial results for the second quarter of 2010. Consolidated net sales for Q2 2010 were $317.0 million, an increase of 21% from $261.4 million in Q2 2009. Consolidated gross profit increased to $40.6 million in Q2 2010 compared to $35.8 million in Q2 2009. Consolidated gross profit margin was 12.8% in Q2 2010 compared to 13.7% in Q2 2009. Consolidated operating profit for Q2 2010 increased 45% to $2.8 million compared to consolidated operating profit of $2.0 million for Q2 2009. Q2 2010 results included a $0.4 million increase in costs due to an appreciation of the Canadian dollar relative to the United States dollar and a $0.5 million increase in depreciation expense over Q2 2009 reflecting our IT investments in systems and infrastructure upgrades. The total of these items is $0.9 million. Consolidated net income for Q2 2010 increased 67% to $1.4 million compared to consolidated net income of $0.8 million for Q2 2009. Diluted earnings per share for Q2 2010 was $0.11 compared to diluted EPS of $0.06 for Q2 2009. Adjusted EBITDA (as defined below) for Q2 2010 increased 46% to $5.4 million from $3.7 million in Q2 2009. Information about our use of non-GAAP financial information is provided below under “Non-GAAP Measures.”

Commenting on the Company’s second quarter results, Frank Khulusi, Chairman, President and CEO of PC Mall, Inc. said, “I am pleased with our second quarter consolidated results. Our year-over-year growth rate significantly accelerated from the first quarter. Our consolidated sales grew 26% over Q2 last year, excluding sales of Sun Microsystems’ solutions, which were negatively affected by Oracle’s acquisition of Sun. Our commercial sales companies showed very strong year-over-year growth, with SMB growing 26% year-over-year and MME growing 36% year-over-year. We believe that this growth was driven by both an improving demand environment and by the investments that we have been making in our businesses, which are beginning to pay off. I am especially pleased that our consolidated operating profit grew 45% over Q2 last year, driven primarily by large increases in both our SMB and MME segments. Additionally, our previously discussed strategy shift in our MacMall segment has continued to pay off as evidenced by a 130% sequential improvement in MacMall operating profit from Q1 to Q2, marking our second straight quarter of sequential operating profit growth.”

Khulusi continued, “In Q2, we also continued to invest in the growth of our service business, and in late Q2 our SARCOM subsidiary acquired the assets of Network Services Plus, Inc., or NSPI, a managed services provider. NSPI’s areas of focus compliment our own very well, and include data center services, remote managed IT services, including support of desktops, servers, networks and VoIP telephony systems, and professional services.”

“Looking forward, our results in Q2 support our previously announced goal of achieving a 1.5% to 2.0% quarterly non-GAAP operating profit margin by the fourth quarter of this year, and we remain committed to that goal,” concluded Khulusi.

Segment Results

SMB

Q2 2010 net sales for our SMB segment were $107.7 million, an increase of $22.4 million, or 26%, from $85.3 million in Q2 2009 primarily due to improved account executive productivity, an improvement in the demand environment and an increase in revenues from SMB’s new sales office located in Chicago.

SMB gross profit increased by $3.1 million, or 27%, to $14.7 million in Q2 2010 compared to $11.6 million in Q2 2009 resulting primarily from the increased SMB net sales discussed above. SMB gross profit margin remained unchanged at 13.6% in Q2 2010 compared to Q2 2009 reflecting improvements due to seasonally strong enterprise software sales and a normalization of competitive pricing pressures, offset by a 71 basis point decline in vendor consideration as a percentage of net sales.

SMB operating profit in Q2 2010 increased by $1.8 million, or 32%, to $7.6 million compared to $5.8 million in Q2 2009. The increase in SMB operating profit in Q2 2010 was primarily due to the increase in SMB gross profit discussed above, partially offset by a $1.1 million increase in personnel costs. This increase in personnel costs in Q2 2010 was primarily due to a $0.3 million impact of a higher Canadian exchange rate, the investment in our Chicago office and our addition of account executives in that facility, and an increase in variable commission and bonus expenses due to the increased SMB gross profit discussed above.

MME

Q2 2010 net sales for our MME segment were $125.5 million compared to $92.4 million in Q2 2009, an increase of $33.1 million, or 36%. This increase was primarily due to increased spending by customers in the mid-market and enterprise sector in Q2 2010, which included a few large transactions with enterprise accounts. Product revenues increased by 50% in Q2 2010 compared to Q2 2009 while service revenues decreased by 7% in Q2 2010 compared to Q2 2009. Service revenues represented 17% of MME net sales in Q2 2010 compared to 25% of sales in Q2 2009. The service revenue decline was primarily due to a 18% decline in MME’s Sarcom branded professional and managed services in Q2 2010 compared to Q2 2009 resulting from certain large service projects in Q2 2009 that did not reoccur in Q2 2010. The decline in service revenues was partially offset by a 14% increase in services performed under our Abreon brand, which is primarily focused on change management and eLearning consulting. MME’s service revenue vehicles are primarily contract-based and have longer lead times.

MME gross profit increased by $2.8 million, or 18%, to $18.6 million in Q2 2010 compared to $15.8 million in Q2 2009, and MME gross profit margin decreased to 14.9% in Q2 2010 compared to 17.1% in Q2 2009. The increase in MME gross profit was due to the increase in MME net sales discussed above. The decrease in MME gross profit margin was primarily due to the impact of the few large transactions mentioned above that were sold at lower margins, combined with the relative decreased mix of service sales during the quarter.

MME operating profit in Q2 2010 increased by $1.3 million, or 29%, to $6.0 million compared to $4.7 million in Q2 2009. The increase in MME operating profit was primarily due to the increase in MME gross profit discussed above, partially offset by a $0.9 million increase in personnel costs due in part to an increase in variable compensation costs related to the increased gross profit discussed above, a $0.2 million increase in bad debt expense and a $0.2 million increase in telecommunication expenses.

Public Sector

Q2 2010 net sales for our Public Sector segment were $41.1 million compared to $38.0 million in Q2 2009, an increase of $3.1 million, or 8%. This increase in Public Sector net sales was due to a 34% increase in net sales of our state and local government and educational institution business driven by stronger demand and our aggressive public sector market share growth strategy. These increases were partially offset by a 7% decrease in our federal government business due to reductions in sales of Sun Microsystems, substantially related to the acquisition of Sun by

Oracle and resulting vendor program changes in connection with Sun solutions. These changes also had a significant negative impact on federal sales through a large contract vehicle. Sales in our federal government business excluding Sun Microsystems increased 58% over the prior year.

Public Sector gross profit decreased by $1.2 million, or 32%, to $2.6 million in Q2 2010 compared to $3.8 million in Q2 2009. Public Sector gross profit margin decreased to 6.3% in Q2 2010 compared to 10.0% in Q2 2009. The decrease in Public Sector gross profit and gross profit margin was primarily due to the impact of the Sun changes mentioned above. Gross profit margin also reflects our previously stated market share growth strategy in the Public Sector business, specifically on the Wintel platform in order to broaden our sales mix.

In Q2 2010, our Public Sector segment had an operating loss of $0.8 million compared to an operating profit of $0.8 million in Q2 2009. The decrease in Public Sector operating profit from Q2 2009 was primarily due to the decrease in Public Sector gross profit discussed above and an increase in Public Sector personnel costs of $0.4 million, resulting from our investment in Public Sector’s Health Dynamix division and incremental investments in headcount.

MacMall

Q2 2010 net sales for our MacMall segment were $42.7 million compared to $45.8 million in Q2 2009, a decrease of $3.1 million, or 7%. Sales in our MacMall segment declined primarily due to our previously announced intentional strategy shift in Q1 2010 to focus the MacMall brand on higher profit customer segments such as small businesses, creative professionals and high-end consumers.

MacMall gross profit increased by $0.1 million, or 2%, to $4.7 million in Q2 2010 compared to $4.6 million in Q2 2009. MacMall gross profit margin increased to 11.1% in Q2 2010 compared to 10.1% in Q2 2009. The increase in MacMall gross profit and MacMall gross profit margin was primarily due to the aforementioned intentional strategy shift.

MacMall operating profit increased by $0.8 million to $1.3 million in Q2 2010 compared to $0.5 million in Q2 2009. The increase in MacMall operating profit was primarily due to a $0.7 million decrease in advertising expenditures and the $0.1 million increase in MacMall gross profit discussed above, each of which was facilitated by our strategy shift. MacMall operating profit also increased sequentially from $0.6 million in Q1 2010.

Corporate & Other

Corporate & Other operating expenses includes corporate related expenses such as legal, accounting, information technology, product management and other administrative costs that are not otherwise included in our reportable operating segments. Q2 2010 Corporate & Other SG&A expenses increased by $1.6 million, or 16%, to $11.3 million from $9.7 million in Q2 2009. The increase from Q2 2009 was primarily related to an increase in personnel costs of $0.6 million, which included $0.2 million increase in stock-based compensation expenses, and an increase in depreciation expenses of $0.4 million primarily related to the completed portions of our ERP and infrastructure upgrades. Results in Q2 2010 also include approximately $0.2 million related to legal costs associated with our acquisition of NSPI.

Consolidated Balance Sheet

Accounts receivable at June 30, 2010 of $170.0 million increased by $8.5 million from December 31, 2009, primarily due to the significant increase in our MME sales in the latter part of Q2 2010. Our inventory of $52.9 million at June 30, 2010 represents a decrease of $15.7 million from December 31, 2009, reflecting sell-through of seasonal purchases made in late 2009 as well as sell-through of our Public Sector backlog that existed at year end, offset by increases in inventory supporting our MME segment. Accounts payable at June 30, 2010 of $103.3 million decreased by $5.5 million from December 31, 2009. Outstanding borrowings under our line of credit increased by $11.7 million to $64.8 million at June 30, 2010 compared to December 31, 2009.

Non-GAAP Measures

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. Adjusted EBITDA eliminates the effect of non-recurring, special charges, if any, as well as non-cash stock-based compensation expense. In the quarter and year-to-date periods ending Q2 2010 and Q2 2009, adjusted EBITDA excludes only non-cash stock-based compensation expenses, as there were no reported non-recurring, special charges during those periods. Adjusted 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 adjusted EBITDA 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. Stock-based compensation is governed by the compensation committee of our Board of Directors and results in a non-cash operating expense for stock option grants that were made in prior operating periods. Additionally, we are also presenting our income tax expense on a non-GAAP basis, which is a consolidated financial measure, excluding the impact of an international tax adjustment in Q2 2009. We believe that the exclusion of the international tax adjustment, which is non-recurring year over year, from our results 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. We believe that such international tax adjustment is not part of our ordinary business. A reconciliation of the non-GAAP consolidated financial measures is included in a table below.
