U.S. AUTO PARTS NETWORK, INC. REPORTS SECOND QUARTER 2008 RESULTS

·  
Net sales of $43.1 million
·  
Gross profit of $14.6 million or 33.9% gross margin
·  
Adjusted EBITDA of $1.9 million

CARSON, California, August 5, 2008 ― U.S. Auto Parts Network, Inc. (NASDAQ: PRTS), a leading online provider of automotive aftermarket parts and accessories, today reported financial results for the second quarter ended June 30, 2008.

Net sales for the second quarter were $43.1 million, an increase of 2.4% from $42.1 million in the prior year period and an increase of 7.8% from $40.0 million in the first quarter of 2008.  Net loss for the second quarter of 2008 was $12.1 million, or $0.40 per diluted share, compared to a net income of $0.8 million, or $0.03 per diluted share for the prior year period.  Diluted EPS for the quarters ended June 30, 2008 and 2007 included amortization expense related to intangibles of $2.0 million or $0.07 per diluted share and $2.1 million or $0.07 per diluted share, respectively.  Diluted EPS for the quarter ended June 30, 2008 also included an impairment loss on intangibles of $18.4 million or $0.62 per diluted share.

“We are pleased to see sequential and year over year sales growth,” stated Shane Evangelist, Chief Executive Officer.  “We attribute this growth to our continued focus on the customer experience including improvements in our contact center, increased product availability and improved site navigation.   We believe the steps taken during the second quarter will enable us to reach a broader audience and help ensure a seamless end-to-end customer experience, thereby positioning U.S. Auto Parts to capture market share of the increasing online aftermarket auto parts market.”

The Company generated adjusted EBITDA of $1.9 million in the second quarter of 2008 compared to $3.8 million in the prior year period.  Included in the second quarter of 2008 were $600,000 of severance, recruiting, and relocation costs.  Adjusted EBITDA is a non-GAAP financial measure that further adjusts EBITDA to exclude share-based compensation expense of $0.7 million in the second quarter of 2008 and $0.6 million in the prior year period.  Adjusted EBITDA also excludes an impairment charge on its intangible assets of $18.4 million in the second quarter of 2008.  For further information regarding Adjusted EBITDA, including a reconciliation of Adjusted EBITDA to net income (loss), see Non-GAAP Financial Measures below.

2Q 2008 Financial Highlights

·  
Net sales for the second quarter ended June 30, 2008 were $43.1 million, an increase of 2.4% from $42.1 million in the second quarter of 2007.  The increase was primarily attributable to a 1.9% increase in our e-commerce channel and an18.9% increase in our online marketplaces channel, both partially offset by a decrease in our offline sales of $0.6 million or 14.3%.  

·  
Gross profit was $14.6 million or 33.9% of net sales for the second quarter of 2008 compared to $13.8 million or 32.8% of net sales for the second quarter of 2007.  The increase in gross margin was primarily due to a mix shift to in stock product distribution, lower product costs from certain suppliers, partially offset by higher outbound freight costs.

·  
Online advertising expense was $2.5 million or 5.8% of net sales for the second quarter of 2008 compared to $2.2 million or 5.2% of net sales for the prior year period.  The increase in marketing spend was largely the result of the termination of marketing co-op reimbursements from a significant supplier, which is now included as a reduction in direct product costs, partially offset by increased efficiency in marketing spend as well as the introduction of additional affiliate marketing relationships.

·  
Marketing expense, excluding advertising expense, was $4.1 million or 9.5% of net sales for the second quarter of 2008 compared to $2.7 million or 6.4% of net sales in the prior year period.  The increase was primarily due to costs associated with establishing and deploying category teams, website development and the expansion of our call center operations.

·  
General and administrative expense was $4.6 million or 10.7% of net sales for the second quarter of 2008 compared to $3.7 million or 8.8% of net sales in the prior year period.  This increase was primarily due to $0.5 million of higher payroll and related expenses due to increased headcount; an increase of $0.3 million in amortization expense and an increase in other administrative costs.

·  
Fulfillment expense was $2.4 million or 5.6% of net sales in the second quarter of 2008 compared to $1.9 million or 4.5% in the prior year period.  The increase in fulfillment was primarily due to higher payroll and associated costs related to the hiring of additional warehouse and purchasing personnel and increased depreciation expense.

·  
Technology expense was $0.8 million or 1.9% of net sales in the second quarter of 2008 compared to $0.5 million or 1.2% of net sales in the prior year period.

·  
Capital expenditures for the second quarter of 2008 totaled $1.0 million, including $0.5 million of internally developed software and website development costs compared to $1.0 million in the same period last year.

·  
Cash, cash equivalents and short term investments were $34.1 million at June 30, 2008.  The Company includes $6.7 million of investments in auction rate preferred securities in long-term assets, which are not included in cash.

“During the second quarter, we focused on driving sustainable improvements in our operating metrics and optimizing our performance drivers,” stated Michael McClane, Chief Financial Officer.  “We have seen some early wins in revenue capture, conversion rate and gross margin, and anticipate increased progress during the remainder of the year.  The entire team is focused on driving sales growth, while closely managing our expenses and improving our cost structure.”

2Q 2008 Operating Metrics

·  
Conversion rate - The conversion rate in the second quarter of 2008 was 1.39% compared to 1.37% during the corresponding period of 2007 and 1.21% for the first quarter of 2008.

·  
Customer acquisition cost - The customer acquisition cost in the second quarter of 2008 was $5.23 per customer, compared to $4.83 during the corresponding period of 2007, and compared to $5.11 in the first quarter of 2008.   Excluding the marketing co-op from all periods, customer acquisition cost would have been $5.77 in the second quarter of 2008 compared to $6.67 in the prior year period and $6.26 in the first quarter of 2008.  Going forward we will report customer acquisition cost excluding marketing co-op reimbursements.  Customer acquisition costs after marketing co-op, are lower as a result of higher levels of organic traffic and more efficient advertising spend.

·  
Unique visitors - The number of monthly unique visitors in the second quarter of 2008 rose to 24.1 million, an increase of 7.6% compared to the second quarter of 2007, and a decrease of 8.7% over the first quarter of 2008.

·  
Orders - The number of orders placed through our e-commerce websites was approximately 334,000 orders in the second quarter of 2008 compared to 306,000 in the corresponding period of 2007 and 320,000 in the first quarter of 2008.

·  
Average order value - The average order value of purchases on our websites was $128 during the second quarter of 2008, down from $132 during the corresponding period of 2007, and just above $126 for the first quarter of 2008.
 
Guidance

Guidance for the quarter ended September 30, 2008 is as follows:

·  
Net sales are expected to be in the range of approximately $38 million to $41 million
·  
Adjusted EBITDA is expected to be in the range of approximately $1.8 million to $2.8 million

For the year ended December 31, 2008, the Company continues to expect revenues in the second half of 2008 to increase in comparison to the second half of 2007 as the Company’s 2008 operational strategy takes hold.

Non-GAAP Financial Measures

Regulation G, "Conditions for Use of Non-GAAP Financial Measures," and other provisions of the Securities Exchange Act of 1934, as amended, define and prescribe the conditions for use of certain non-GAAP financial information. We provide "Adjusted EBITDA,” which is a non-GAAP financial measure. Adjusted EBITDA consists of net income before (a) interest income (expense), net; (b) income tax provision (benefit); (c) amortization of intangibles and impairment loss; (d) depreciation and amortization; and (e) share-based compensation expense related to stock options.

The Company believes this non-GAAP financial measure provides important supplemental information to management and investors. This non-GAAP financial measure reflects an additional way of viewing aspects of the Company's operations that, when viewed with the GAAP results and the accompanying reconciliation to corresponding GAAP financial measures, provides a more complete understanding of factors and trends affecting the Company's business and results of operations.

Management uses Adjusted EBITDA as a measurement of the Company's operating performance because it assists in comparisons of the Company's operating performance on a consistent basis by removing the impact of items not directly resulting from core operations. Internally, this non-GAAP measure is also used by management for planning purposes, including the preparation of internal budgets; for allocating resources to enhance financial performance; for evaluating the effectiveness of operational strategies; and for evaluating the Company's capacity to fund capital expenditures and expand its business. The Company also believes that analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate the overall operating performance of companies in our industry.  Additionally, lenders or potential lenders use Adjusted EBITDA to evaluate the Company’s ability to repay loans.

This non-GAAP financial measure is used in addition to and in conjunction with results presented in accordance with GAAP and should not be relied upon to the exclusion of GAAP financial measures. Management strongly encourages investors to review the Company's consolidated financial statements in their entirety and to not rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names. In addition, the Company expects to continue to incur expenses similar to the non-GAAP adjustments described above, and exclusion of these items from the Company's non-GAAP measures should not be construed as an inference that these costs are unusual, infrequent or non-recurring.
