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

- Net sales increased to $161 million for 2007
- Securities litigation preliminarily settled

CARSON, Calif., March 6 /PRNewswire-FirstCall/ -- 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

    -- Net sales for the fourth quarter ended December 31, 2007 were $37.3
       million, an increase of 1.4% from $36.8 million in the prior year
       period.  The sales growth primarily reflected higher website traffic
       (unique visitors), offset by a lower conversion rate.

    -- Gross profit was $12.7 million or 34% of net sales for the fourth
       quarter of 2007 compared to $12.0 million or 33% of net sales for the
       fourth quarter of 2006.  The year-over-year increase in gross margin
       was primarily due to a 1.3% increase in online margins which resulted
       from higher prices on certain products, lower product costs from
       certain suppliers and lower shipping costs.

    -- Marketing expense was $5.8 million or 16% of net sales for the fourth
       quarter of 2007 compared to $5.0 million or 14% of net sales for the
       prior year period.  Marketing costs increased primarily due to a $0.3
       million increase in paid search in the first half of the 2007 fourth
       quarter.  We continue to evaluate our investment in paid search in
       order to balance our return on investment in marketing spend with our
       ability to drive organic traffic.

    -- General and administrative expense was $8.9 million or 24% of net sales
       for the fourth quarter of 2007 compared to $2.6 million or 7% of net
       sales in the prior year period.  G&A expense increased over the same
       period in the previous year primarily due to the inclusion of the $3.9
       million litigation settlement charge, an increase of $0.7 million in
       costs associated with the hiring of a new CEO, an increase of $0.4
       million in severance expense related to recent management changes, and
       an increase of $0.2 million in share-based compensation expense.

    -- Capital expenditures for the fourth quarter of 2007 totaled $1.5
       million, including $0.7 million of internally developed software and
       website development costs.

    -- Cash, cash equivalents and short term investments were $42.0 million at
       December 31, 2007.

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.

    -- Conversion rate -- The conversion rate in the fourth quarter of 2007
       was 1.0% compared to 1.2% during the corresponding period of 2006.
       Conversion based on our new measurement criteria remained stable at
       1.2% for the third and fourth quarters of 2007.

    -- Customer acquisition cost -- The customer acquisition cost in the
       fourth quarter of 2007 was $10 per customer, compared to $9 during the
       corresponding period of 2006.  The increase in customer acquisition
       cost was primarily due to increased paid search costs in the current
       quarter.  Customer acquisition cost based on our new measurement
       criteria was $8 per customer for the fourth quarter of 2007, compared
       to $5 for the third quarter of 2007.

    -- Unique visitors -- The number of monthly unique visitors in the fourth
       quarter of 2007 rose to 24 million, an increase of 20% compared to the
       fourth quarter of 2006.  The increase primarily reflects increases in
       both paid and organic search.  Unique visitors based on our new
       measurement criteria were 25 million for the fourth quarter of 2007,
       compared to 24 million for the third quarter of 2007.

    -- Orders -- The number of orders placed through our e-commerce websites
       was approximately 238,000 orders in the fourth quarter of 2007 compared
       to 241,000 in the corresponding period of 2006.  The decrease in orders
       was primarily a result of a decrease in conversion rate.  E-commerce
       orders based on our new measurement criteria were 293,000 for the
       fourth quarter of 2007, compared to 297,000 for the third quarter of
       2007.

    -- Average order value -- The average order value of purchases on our
       websites was $118 during the fourth quarter of 2007, down from $119
       during the corresponding period of 2006.  The reduction in average
       order value was primarily the result of lower sales volume of higher
       value products, in addition to promotional discounts offered in the
       fourth quarter of 2007.  Average order value based on our new
       measurement criteria was $125 for the fourth quarter of 2007, compared
       to $127 for the third quarter of 2007.

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:

    -- Net sales are expected to be in the range of approximately $38 million
       to $40 million.
    -- Adjusted EBITDA is expected to be in the range of approximately $1.6
       million to $2.1 million.

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; (c) 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.
