Aterian Reports First Quarter 2023 Results

Reports First Quarter 2023 Net Revenue of $34.9 Million

Announces Headcount Reduction Geared to Achieve Adjusted EBITDA Profitability Target

NEW YORK, May 9, 2023 – Aterian, Inc. (Nasdaq: ATER) (“Aterian” or the “Company”) today announced results for the first quarter ended March 31, 2023.

First Quarter Highlights

“Despite weakness in consumer demand, we are continuing to execute on our goal of becoming adjusted EBITDA profitable in the second half of this year,” commented Yaniv Sarig, Co-Founder and Chief Executive Officer of Aterian. “To that end today we announced a headcount reduction that will save an annualized $6 million toward our target of adjusted EBITDA profitability. It is a difficult decision but one that will put Aterian on a better footing with a solid balance sheet. This cost savings coupled with our portfolio’s market share position will allow us to build forward with emphasis and focus on both growth and profitability.”

Headcount Reduction

The Company plans to reduce expenses by implementing a reduction in its current workforce leading to approximately $6.0 million of annualized savings. This headcount reduction will impact approximately 70 employees and 30 contractors, primarily in the Philippines. The reduction in headcount is part of the Company’s strategy to increase efficiency and to drive focus as part of its second half 2023 adjusted EBITDA profitability goal. The Company expects to substantially complete the reduction in headcount by the end of the second quarter of 2023. The Company expects to recognize restructuring charges in connection with the headcount reduction plan, primarily from severance, of between $1.0 million to $1.3 million. The Company expects the charges will be recognized primarily in the second quarter of 2023, with the majority of such charges anticipated to be paid by the end of the third quarter of 2023.

As part of this headcount reduction, our Chief Supply Chain Officer, Michal Chaouat-Fix, will be transitioning away from the Company. Arturo Rodriguez, our Chief Financial Officer, will also assume the additional responsibilities of supply chain and operations as our Interim Chief Operating Officer. In addition, Tim Stanton, our Chief E-Commerce Officer, will transition away from the Company, Phil Lepper, our Senior Vice President of Revenue will assume Tim’s responsibilities.

Second Quarter 2023 & Second Half of 2023 Outlook

For the second quarter of 2023, taking into account the current global environment and inflation, we believe that net revenue will be between $37 million and $44 million. For the second quarter of 2023, the Company expects an Adjusted EBITDA loss of between $(5.2) million to $(6.2) million including the restructuring charges from our headcount reductions.

As a result of the headcount reduction, the Company is reconfirming its prior guidance of expecting to be Adjusted EBITDA profitable in the second half of 2023.

Non-GAAP Financial Measures

For more information on our non-GAAP financial measures and a reconciliation of GAAP to non-GAAP measures, please see the “Non-GAAP Financial Measures” section below. The most directly comparable GAAP financial measure for EBITDA and Adjusted EBITDA is net loss and we expect to report a net loss for the three months ending March 31, 2023 and the second half of 2023, due primarily to interest expense and stock-based compensation expense. We are unable to reconcile the forward-looking statements of EBITDA and Adjusted EBITDA in this press release to their nearest GAAP measures because the nearest GAAP financial measures are not accessible on a forward-looking basis and reconciling information is not available without unreasonable effort.

Non-GAAP Financial Measures

We believe that our financial statements and the other financial data included in this Quarterly Report have been prepared in a manner that complies, in all material respects, with generally accepted accounting principles in the U.S. (“GAAP”). However, for the reasons discussed below, we have presented certain non-GAAP measures herein.

We have presented the following non-GAAP measures to assist investors in understanding our core net operating results on an on-going basis: (i) Contribution Margin; (ii) Contribution margin as a percentage of net revenue; (iii) EBITDA (iv) Adjusted EBITDA; and (v) Adjusted EBITDA as a percentage of net revenue. These non-GAAP financial measures may also assist investors in making comparisons of our core operating results with those of other companies.

As used herein, Contribution margin represents gross profit less e-commerce platform commissions, online advertising, selling and logistics expenses (included in sales and distribution expenses). As used herein, Contribution margin as a percentage of net revenue represents Contribution margin divided by net revenue. As used herein, EBITDA represents net loss plus depreciation and amortization, interest expense, net and provision for income taxes. As used herein, Adjusted EBITDA represents EBITDA plus stock-based compensation expense, changes in fair-market value of earn-outs, profit and loss impacts from the issuance of common stock and/or warrants, changes in fair-market value of warrant liability, litigation settlements, impairment on goodwill and intangibles, gain from extinguishment of debt and other expenses, net. As used herein, Adjusted EBITDA as a percentage of net revenue represents Adjusted EBITDA divided by net revenue. Contribution margin, EBITDA and Adjusted EBITDA do not represent and should not be considered as alternatives to loss from operations or net loss, as determined under GAAP.

We present Contribution margin and Contribution margin as a percentage of net revenue, as we believe each of these measures provides an additional metric to evaluate our operations and, when considered with both our GAAP results and the reconciliation to gross profit, provides useful supplemental information for investors. Specifically, Contribution margin and Contribution margin as a Non-GAAP Financial Measure percentage of net revenue are two of our key metrics in running our business. All product decisions made by us, from the approval of launching a new product and to the liquidation of a product at the end of its life cycle, are measured primarily from Contribution margin and/or Contribution margin as a percentage of net revenue. Further, we believe these measures provide improved transparency to our stockholders to determine the performance of our products prior to fixed costs as opposed to referencing gross profit alone.

In the reconciliation to calculate contribution margin, we add e-commerce platform commissions, online advertising, selling and logistics expenses (“sales and distribution variable expense”) to gross profit to inform users of our financial statements of what our product profitability is at each period prior to fixed costs (such as sales and distribution expenses such as salaries as well as research and development expenses and general administrative expenses). By excluding these fixed costs, we believe this allows users of our financial statements to understand our products performance and allows them to measure our products performance over time.

We present EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue because we believe each of these measures provides an additional metric to evaluate our operations and, when considered with both our GAAP results and the reconciliation to net loss, provide useful supplemental information for investors. We use these measures with financial measures prepared in accordance with GAAP, such as sales and gross margins, to assess our historical and prospective operating performance, to provide meaningful comparisons of operating performance across periods, to enhance our understanding of our operating performance and to compare our performance to that of our peers and competitors. We believe EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue are useful to investors in assessing the operating performance of our business without the effect of non-cash items.

Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue should not be considered in isolation or as alternatives to net loss, loss from operations or any other measure of financial performance calculated and prescribed in accordance with GAAP. Neither EBITDA, Adjusted EBITDA or Adjusted EBITDA as a percentage of net revenue should be considered a measure of discretionary cash available to us to invest in the growth of our business. Our Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue may not be comparable to similar titled measures in other organizations because other organizations may not calculate Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA or Adjusted EBITDA as a percentage of net revenue in the same manner as we do. Our presentation of Contribution margin and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by the expenses that are excluded from such terms or by unusual or non-recurring items.

We recognize that EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue, have limitations as analytical financial measures. For example, neither EBITDA nor Adjusted EBITDA reflects:

• our capital expenditures or future requirements for capital expenditures or mergers and acquisitions;

• the interest expense or the cash requirements necessary to service interest expense or principal payments, associated with indebtedness;

• depreciation and amortization, which are non-cash charges, although the assets being depreciated and amortized will likely have to be replaced in the future, or any cash requirements for the replacement of assets;

• changes in cash requirements for our working capital needs; or

• changes in fair value of contingent earn-out liabilities, warrant liabilities, and amortization of inventory step-up from acquisitions (included in cost of goods sold).

Additionally, Adjusted EBITDA excludes non-cash expense for stock-based compensation, which is and is expected to remain a key element of our overall long-term incentive compensation package.

We also recognize that Contribution margin and Contribution margin as a percentage of net revenue have limitations as analytical financial measures. For example, Contribution margin does not reflect:

• general and administrative expense necessary to operate our business; •research and development expenses necessary for the development, operation and support of our software platform;

• the fixed costs portion of our sales and distribution expenses including stock-based compensation expense; or

• changes in fair value of contingent earn-out liabilities, warrant liabilities, and amortization of inventory step-up from acquisitions (included in cost of goods sold).

Contribution Margin

Contribution margin represents gross profit less e-commerce platform commissions, online advertising, selling and logistics expenses (included in sales and distribution expenses). Contribution margin as a percentage of net revenue represents Contribution margin divided by net revenue. The following table provides a reconciliation of Contribution margin to gross profit and Contribution margin as a percentage of net revenue to gross profit as a percentage of net revenue, which are the most directly comparable financial measures presented in accordance with GAAP:

Adjusted EBITDA

The following table provides a reconciliation of EBITDA and Adjusted EBITDA to net loss, which is the most directly comparable financial measure presented in accordance with GAAP:

Each of our products typically goes through the Launch phase and depending on its level of success is moved to one of the other phases as further described below:

i. Launch phase: During this phase, we leverage our technology to target opportunities identified using AIMEE (Artificial Intelligence Marketplace e-Commerce Engine) and other sources. This phase also includes revenue from new product variations and relaunces. During this period of time, due to the combination of discounts and investment in marketing, our net margin for a product could be as low as approximately negative 35%. Net margin is calculated by taking net revenue less the cost of goods sold, less fulfillment, online advertising and selling expenses. These primarily reflect the estimated variable costs related to the sale of a product.

ii. Sustain phase: Our goal is for every product we launch to enter the sustain phase and become profitable, with a target of positive 15% net margin for most products, within approximately three months of launch on average. Net margin primarily reflects a combination of manual and automated adjustments in price and marketing spend.

iii. Liquidate phase: If a product does not enter the sustain phase or if the customer satisfaction of the product (i.e., ratings) is not satisfactory, then it will go to the liquidate phase and we will sell through the remaining inventory. Products can also be liquidated as part of inventory normalization especially when steep discounts are required.

The following tables break out our first quarter of 2022 and 2023 results of operations by our product phases (in thousands):
