Q4 2013 Financial Highlights

•

Net sales decreased to $59.7 million for Q4 2013 compared to $62.8 million for Q4 2012. Our Q4 2013 net sales consisted of online sales, representing 89.3% of the total (compared to 89.8% in Q4 2012), and offline sales, representing 10.7% of the total (compared to 10.2% in Q4 2012). The net sales decrease was primarily due to a decline of $3.1 million, or 5.5%, in online sales. Online sales decreased primarily due to a $4.5 million reduction in sales from websites eliminated in 2013 partially offset by a $1.5 million increase in revenues from our continued sales channels. Overall we realized a net 21.1% reduction in unique visitors and a decline in the total number of orders by 15.2%. Our offline sales, which consist of our Kool-Vue and wholesale operations were essentially flat with last year.

•

Gross profit decreased to $17.5 million for Q4 2013 compared to $17.8 million for Q4 2012. Gross margin rate increased 1.0% to 29.3% in Q4 2013 compared to 28.3% in Q4 2012. Gross margin was unfavorably impacted last year from a write down of inventory slated for return to suppliers.

•

Marketing expense was $9.3 million or 15.5% of net sales in Q4 2013, down from $12.1 million or 19.2% of net sales in Q4 2012. Online advertising expense, which includes catalog costs, was $3.7 million or 7.0% of online sales for Q4 2013 compared to $4.8 million or 8.5% of online sales for Q4 2012. Online advertising expense decreased primarily due to the reduction in our non-catalog online advertising expenses, which includes listing and placement fees paid to commercial and search engine websites. Marketing expense, excluding advertising costs, was $5.6 million or 9.3% of net sales for Q4 2013 compared to $7.3 million or 11.6% of net sales for Q4 2012. The decline was primarily due to lower depreciation and amortization expense due to certain assets that were fully depreciated, lower wages, and lower overhead expenses incurred in Q4 2013 as compared to Q4 2012.

•

General and administrative expense was $3.9 million or 6.6% of net sales in Q4 2013 as compared to $4.3 million or 6.9% of net sales for Q4 2012. The decrease was primarily due to lower merchant processing fees on lower online sales and reduced legal expense compared to Q4 2012.

•

Fulfillment expense was $4.1 million or 6.9% of net sales in Q4 2013 compared to $5.0 million or 8.0% of net sales in Q4 2012. The decrease in Q4 2013 was primarily due to lower depreciation and amortization expense, reduced overhead expenses and lower salaries and warehouse wages as compared to Q4 2012.

•

Technology expense was $1.1 million or 1.8% of net sales in Q4 2013 compared to $1.4 million or 2.3% of net sales in Q4 2012. The decrease was primarily due to a reduction in technology wages, lower consulting expense, and lower telephone expense.

•

We did not incur any impairment charges during Q4 2013. In Q4 2012, we recorded impairment losses on goodwill, property and equipment and intangible assets of $18.9 million, $1.9 million and $5.6 million, respectively, due to declines in the Company’s overall financial performance.

•

Capital expenditures for Q4 2013 were $1.6 million.

•

Cash and cash equivalents and investments were $0.9 million and total debt under our revolver was $6.8 million as of December 28, 2013 compared to $1.2 million and $8.3 million as of September 28, 2013.

As we consolidated to fewer websites, we changed the measurement source of our unique visitors data to different third-party provider of that data in the first quarter of 2013. Previously reported operating metrics data for the fourth quarter of 2012 was revised to conform to the current third-party provider’s data.

2	Visitors do not include traffic from media properties (e.g. AutoMD).

3	Revenue capture is the amount of actual dollars retained after taking into consideration returns, credit card declines and product fulfillment.

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) depreciation and amortization expense; (d) amortization of intangible assets; (e) share-based compensation expense; (f) impairment losses; (g) legal costs; (h) loss on extinguishment of debt and (i) restructuring costs.

The Company believes that this non-GAAP financial measure provides important supplemental information to management and investors. This non-GAAP financial measure reflect 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 measure of the Company’s operating performance because it assists in comparing 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.
