U.S. Auto Parts Network, Inc. Reports Full Year 2007 Results

CARSON, California, March 6, 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 fourth quarter and year ended December 31, 2007.

Net sales for 2007 were $161.0 million, an increase of 34% from $120.1 million for 2006.  The Company entered into a memorandum of understanding on January 30, 2008 pursuant to which it reached a preliminary settlement of its outstanding securities litigation, which settlement is subject to court approval and confirmatory discovery.  As a result of this preliminary settlement, the Company recorded a $4.5 million settlement charge in 2007.  Inclusive of the securities litigation settlement charge, net loss for the year ended December 31, 2007 was $3.6 million, or $0.13 per diluted share on approximately 28.3 million shares outstanding, compared to net income of $3.5 million, or $0.17 per diluted share on approximately 20.0 million shares outstanding in 2006.

Net sales for the quarter ended December 31, 2007 were $37.3 million, an increase of 1.4% from $36.8 million in the prior year period.  Net loss for the fourth quarter of 2007, which is inclusive of the fourth quarter portion of the securities litigation settlement costs of $3.9 million, was $5.5 million, or $0.18 per diluted share, compared to a net loss of $0.02 million, or $0.00 per diluted share for the prior year period.   Diluted EPS for the quarters ended December 31, 2007 and 2006 included amortization expense related to intangibles of $2.1 million or $0.07 per diluted share and $2.1 million or $0.9 per diluted share, respectively.

The Company generated adjusted EBITDA of $7.8 million in 2007 compared to $13.3 million in 2006.  Adjusted EBITDA excluded share-based compensation expense of $2.2 million in 2007 and $0.9 million in 2006.  Results for the full year 2007 included the $4.5 million securities litigation settlement charge and approximately $1.1 million in costs associated with the hiring of a new CEO and severance expense for recent management changes.  Adjusted EBITDA is a non-GAAP financial measure.  For further information regarding Adjusted EBITDA, including a reconciliation of Adjusted EBITDA to net income (loss), see Non-GAAP Financial Measures below.

Mr. Evangelist noted, "I believe U.S. Auto Parts has a tremendous opportunity to capture a significant share of the existing online auto parts market and the expected future growth.  Over the last four months, we have listened to consumers, assessed the competitive landscape and analyzed the supply chain complexities.  From these efforts, we have developed a strategy that addresses our near term operational opportunities, and we believe will position U.S. Auto Parts to take advantage of the long-term shift of auto parts buying from brick and mortar retail to online."

4Q 2007 Financial Highlights

Michael McClane, Chief Financial Officer, added, "2007 was a year of many accomplishments and learning opportunities that we believe have set the foundation for future successes to build upon.  We recruited new leadership focused on execution and improving the consumer experience, attracted a world-class board, completed the Partsbin integration, reduced shareholder uncertainty by resolving the lawsuit and most importantly, architected a plan to drive the business over the next several years.  We believe we have a tremendous growth opportunity and we are highly focused on capturing additional market share."

4Q 2007 Operating Metrics

To better manage and measure the business, the Company plans to use a new method to calculate key operating metrics.  The new measurement will be based on placed orders instead of the current method of using net orders.  The Company is doing this to reduce the impact of returns, out of stock orders, and incomplete payment processing on the key operating metrics. In addition, the Company is adjusting the measurement of monthly unique visitors, which the Company believes will improve consistency and usability.

Outlook for 2008

The Company is updating its preliminary guidance for full year 2008 as follows:

Guidance for the quarter ended March 31, 2008 is as follows:

For the year ended December 31, 2008, the Company expects revenues on a year-over-year basis to decline in the first half of 2008 versus the prior year period and increase in the second half of 2008 versus the prior year period as the Company's 2008 operational strategy takes hold.  

Commenting on the Company's guidance policy, Mr. Evangelist stated, "As we are in the early stages of implementing our 2008 operational strategy, we will not be providing full year 2008 guidance.  However, we have identified opportunities that upon full execution, could contribute approximately $45 million in incremental sales, which on an annualized basis should approach $200 million in sales in the next few years.  We believe that the operating leverage inherent in the model can allow us to achieve a 10% Adjusted EBITDA margin on that level of revenue.  We believe we have identified, and are focused on, the right opportunities for operational improvement and while we cannot commit to a specific time table around completion, we believe that we are moving in the right direction to achieve our strategic and financial goals."

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 expense, net; (b) income tax provision; © amortization of intangibles; (d) depreciation and amortization; and (e) share-based compensation expense related to stock option grants and other equity instruments.

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.

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.

The table below reconciles net income (loss) to Adjusted EBITDA for the periods presented:

*Includes $3.9 million and $4.5 million in charges recorded in the fourth quarter of 2007 and the full year 2007, respectively, resulting from the Company's preliminary agreement to settle the shareholder litigation.    

Conference Call

As previously announced, the Company will conduct a conference call with analysts and investors to discuss the results today, Thursday, March 6, 2008, at 2:00 pm Pacific Time (5:00 pm Eastern Time).  The conference call will be conducted by Shane Evangelist, Chief Executive Officer, and Michael McClane, Chief Financial Officer, and will be broadcast live over the Internet and accessible through the Investor Relations section of the Company's website at www.usautoparts.net where the call will be archived until March 20, 2008.  To view the press release or the financial or other statistical information required by SEC Regulation G, please visit the Investor Relations section of the U.S. Auto Parts website at investor.usautoparts.net.
