Aterian Reports 2025 First Quarter Financial Results

Updates Progress of Tariff Mitigation Strategy and Announces Cost Optimization Plan Designed to Reduce Annual Spending by $5 - $6 Million

SUMMIT, NEW JERSEY, May 14, 2025 – Aterian, Inc. (Nasdaq: ATER) (“Aterian” or the “Company”), a consumer products company, today announced financial results for the first quarter ended March 31, 2025 (“Q1 2025”). The Company also provided an update on a series of initiatives that are underway to mitigate the impact of tariffs on the Company’s performance, including the commencement of a cost optimization plan designed to produce annual savings of approximately $5 - $6 million.

“While tariffs did not have a direct impact on our first quarter results, the uncertainty in the broader macroeconomic environment led to some softness in consumer demand,” said Arturo Rodriguez, Chief Executive Officer. “That said, sales seasonality remained consistent with prior years, and we continued to see solid performance across our core products.”

First Quarter 2025 Highlights

All comparisons are to the first quarter ended March 31, 2024 (“Q1 2024”)

Tariff Mitigation Initiatives and Cost Optimization Plan

Mr. Rodriguez continued, “The uncertainty created by tariffs and broader macroeconomic conditions has energized our team to manage those elements of Aterian’s business that are within our control, including: 1) reducing fixed costs; 2) accelerating our plan of re-sourcing and diversifying our manufacturing; 3) hastening our advance towards a more resilient business model by deepening our expansion into consumables, the majority of which will be US-manufactured; and 4) strategically raising prices.”

“The actions we are taking will allow us to maintain an acceptable level of revenue during this transition period, conserve cash, preserve margin, maximize cash flow, and optimize our cost structure, all while maintaining the high level of innovation and customer service that has defined our company. This is a significant undertaking; however, we believe that these initiatives will mitigate the effects of tariffs on our results in 2025 and position Aterian to pivot towards a return to growth and profitability beyond 2025, even under prolonged tariff pressure.”

Tariff Response

Cost Optimization Plan

These initiatives include emphasizing targeted workforce reductions and vendor savings. The plan is expected to generate $5-$6 million of pre-tax cost savings, $5 million of which is expected to be realized by the end of 2025 with the balance realized in 2026. The Company currently estimates that it will incur approximately $2.3 million in total costs associated with the plan.

Guidance Commentary

Josh Feldman, Chief Financial Officer, commented, “The current economic landscape is marked by significant uncertainty, and the rapidly changing market conditions make it challenging to predict future developments. Because of that, we are withdrawing our previously issued net revenue and Adjusted EBITDA guidance for 2025. However, we do believe that the steps underway will soften the impact of tariffs and their related costs for much of 2025. We will continue to evaluate our ability to provide guidance as the year progresses.”

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 are reporting a net loss for the quarter ending March 31, 2025 due primarily to our operating losses, which includes stock-based compensation expense, and interest 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 press release 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 amortization of inventory step-up from acquisitions (included in cost of goods sold) and 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 warrant liability, restructuring expenses, 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 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:

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:

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 relaunches. 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 2024 and 2025 results of operations by our product phases (in thousands):
