Aterian Reports 2025 Third Quarter Financial Results and Reiterates Guidance

Produced Higher Margins, Lower Operating Expenses, and Significantly Narrowed Losses Compared to Q2 2025

New Product Introductions and Sales Channel Expansion Broadening Market Reach

SUMMIT, NEW JERSEY, November 13, 2025 – Aterian, Inc. (Nasdaq: ATER) (“Aterian” or the “Company”), a consumer products company, today announced financial results for the third quarter ended September 30, 2025 (“Q3 2025”) and reiterated net revenue and Adjusted EBITDA guidance for the six months ending December 31, 2025.

"Our team has executed with precision and purpose along multiple fronts, with a focus on expense control, margin enhancement, sales channel expansion, new product introductions, and sourcing diversification,” said Arturo Rodriguez, Chief Executive Officer. “Although we have endured some revenue challenges primarily related to tariffs, our success in executing these strategies drove significant improvements in Operating expenses, margin, and Adjusted EBITDA loss when compared to the second quarter of 2025. We secured new digital shelf space at some of the nation’s leading retailers and entered the consumables market with two new products to date, each of which extends from a trusted Aterian brand and carries an attractive margin profile and recurring revenue opportunities.”

Mr. Rodriguez concluded, “Our efforts to date have positioned Aterian to meet its goals for 2025 and given us confidence in our ability to deliver improved performance beginning in 2026.”

Josh Feldman, Chief Financial Officer, commented, “When compared to the second quarter of 2025, our Q3 2025 gross margin improved by 180 bps, our contribution margin doubled, and we narrowed our Adjusted EBITDA loss by over 80%. We remain confident in our ability to meet our financial forecasts for the second half of 2025. We expect to realize further operational efficiencies in 2026 when our previously announced workforce reductions and vendor savings initiatives fully take hold. We also expect a working capital benefit in 2026 as we draw down inventory purchased in advance of tariffs to meet anticipated customer demand.”

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 September 30, 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, product remediation costs, 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 general and 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 technology and market data to target opportunities. 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.
