Management Commentary

“During the quarter we saw robust sales that reinforced our confidence in achieving our long-term goal of 20 to 25% compounded top line growth” said Lev Peker, CEO of CarParts.com. “The expansion of our DC network into Grand Prairie Texas increased our revenue capacity as well as our ability to meet the exponential growth in demand that we are seeing from customers.”

“The success we achieved is a testament to our data science, inventory forecasting, and global sourcing teams. By optimizing the assortment in Texas, we were able to maximize our sales capabilities despite the facility still being in the ramp up stages. Additionally, our warehouse operations teams worked tirelessly to fulfill an unprecedented amount of customer orders.”

“We also recently began discussions to expand our Texas facility by 156k square feet which will bring our total warehouse footprint to more than 1 million total square feet across the country. This is an exciting milestone for us, and the increased space will allow us to carry a full line of products to serve one of our biggest markets.”

“In the quarter, we also welcomed Henry Maier to our board of directors. Henry is a 35-year veteran of FedEx Corporation, where he currently serves as president and CEO of the FedEx Ground operating unit.”

First Quarter 2021 Financial Results

Net sales in the first quarter of 2021 were $144.8 million compared to $87.8 million in the year-ago quarter. The growth in sales was primarily driven by increased revenue growth from our flagship website, CarParts.com.

Gross profit in the first quarter increased 65% to $49.2 million compared to $29.8 million in the first quarter last year, with gross margin up 10 bps to 34.0% compared to 33.9%. These improvements were driven by favorable channel and product mix, partially offset by higher inbound and outbound freight costs and seasonal surcharges from our carriers.

Total operating expenses in the first quarter were $51.7 million compared to $30.1 million in the first quarter last year. The increase was driven by personnel costs related to the new Texas DC, technology spend, marketing spend and non-cash charges.

Net loss in the first quarter increased to ($2.7) million compared to ($1.0) million in the first quarter last year. The net loss for the first quarter of 2021 was primarily driven by an increase in non-cash charges.

Adjusted EBITDA in the first quarter decreased to $3.6 million compared to $4.3 million in the year-ago quarter, with the decrease driven primarily by the continued ramp up of our Texas DC, adverse weather, and targeted investments in brand awareness campaigns that did not exist in the prior year quarter.

On April 3, 2021, the Company had no revolver debt, no outstanding trade letters of credit (“LCs”) and a cash balance of $45.9 million, compared to no revolver debt, no outstanding trade LCs and a $35.8 million cash balance at prior fiscal year-end January 2, 2021.

Non-GAAP Financial Measures

Regulation G, 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 loss before (a) interest expense, net; (b) income tax provision; (c) depreciation and amortization expense; (d) amortization of intangible assets; and (e) share-based compensation expense. A reconciliation of Adjusted EBITDA to net loss is provided below.

The Company believes that 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 one 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 stock compensation expense and the costs associated with the customs issue, as well as other items that we do not believe are representative of our ongoing operating performance. 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; and for evaluating the effectiveness of operational strategies. The Company also believes that analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate the ongoing operations 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 all unusual, infrequent or non-recurring.

Safe Harbor Statement

This press release contains statements which are based on management’s current expectations, estimates and projections about the Company’s business and its industry, as well as certain assumptions made by the Company. These statements are forward looking statements for the purposes of the safe harbor provided by Section 21E of the Securities Exchange Act of 1934, as amended and Section 27A of the Securities Act of 1933, as amended. Words such as “anticipates,” “could,” “expects,” “intends,” “plans,” “potential,” “believes,” “predicts,” “projects,” “seeks,” “estimates,” “may,” “will,” “would,” “will likely continue” and variations of these words or similar expressions are intended to identify forward-looking statements. These statements include, but are not limited to, statements regarding our future operating results and financial condition, our potential growth and our ability to expand and improve our product offerings. We undertake no obligation to revise or update publicly any forward-looking statements for any reason. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict. Therefore, our actual results could differ materially and adversely from those expressed in any forward-looking statements as a result of various factors.

Important factors that may cause such a difference include, but are not limited to, competitive pressures, our dependence on search engines to attract customers, demand for the Company’s products, the online market and channel mix for aftermarket auto parts, the economy in general, increases in commodity and component pricing that would increase the Company’s product costs, the operating restrictions in its credit agreement, the weather, the impact of the customs issues and any other factors discussed in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including the Risk Factors contained in the Company’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are available at www.carparts.com/investor and the SEC’s website at www.sec.gov. You are urged to consider these factors carefully in evaluating the forward-looking statements in this release and are cautioned not to place undue reliance on such forward-looking statements, which are qualified in their entirety by this cautionary statement. Unless otherwise required by law, the Company expressly disclaims any obligation to update publicly any forward-looking statements, whether as result of new information, future events or otherwise.
