Item 7.01. Regulation FD Disclosure.

On July 10, 2026, Aterian, Inc. (the “Company” or “Aterian”) convened and adjourned, without conducting any business, the special meeting of its stockholders (the “Special Meeting”). At the Special Meeting, a total of 5,278,277 shares, or 48.65% of the shares of the Company’s common stock, par value $0.0001 per share, issued and outstanding and entitled to vote as of May 29, 2026, the record date for the Special Meeting, were present virtually or represented by proxy, constituting a quorum. However, because there were not sufficient votes to approve the Asset Sale Proposal (as defined below) at the time of the Special Meeting, the Company decided to adjourn the Special Meeting.

The Special Meeting will reconvene on July 17, 2026 at 9:30 a.m. Eastern Time via live webcast at www.virtualshareholdermeeting.com/ATER2026SM to provide the Company’s stockholders with additional time to vote on the proposal to approve the sale of substantially all of the assets of the Company (the “Asset Sale”) pursuant to the Asset Purchase Agreement, dated April 27, 2026, by and between the Company and Trademark Global, LLC (as it may be amended, restated, supplemented or otherwise modified from time to time in accordance with the terms thereof) (the “Asset Sale Proposal”), and the other proposals described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (“SEC”) on June 9, 2026, as supplemented from time to time. No changes have been made to the proposals to be voted on by stockholders at the Special Meeting.

The record date for determining stockholder eligibility to vote at the Special Meeting remains the close of business on May 29, 2026. Proxies previously submitted will be voted at the reconvened Special Meeting unless properly revoked, and stockholders who have already submitted a proxy or otherwise voted and do not wish to change their vote need not take any action.

The information furnished pursuant to this Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities under that Section, or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Forward-Looking Statements

All statements other than statements of historical facts included in this Current Report on Form 8-K that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. Examples of these forward-looking statements include statements concerning the proposed Asset Sale, the Investment Transaction, the transactions contemplated thereby, the timing of completing the proposed transactions, the potential benefits of the proposed transactions and the declaration and timing of any potential dividend or distribution of contingent value rights (“CVRs”). These forward-looking statements are based on management’s current expectations and beliefs and are subject to a number of risks and uncertainties and other factors that are difficult to predict, many of which are beyond our control, and that could cause actual results to differ materially and adversely from those described in the forward-looking statements. These risks and uncertainties include, among others: the terms, structure, benefits and costs of each of the Asset Sale, the Investment Transaction, and the transactions contemplated by each of the foregoing; the timing of such transactions and whether such transactions will be consummated; the risk that the Asset Sale, the Investment Transaction, and the transactions contemplated by each of the foregoing, and the announcement of the same, could have an adverse effect on the ability of the Company to retain and hire key personnel and maintain relationships with partners, suppliers, employees, stockholders and other business relationships and on the Company’s operating results and business generally; the risk that the Asset Sale, the Investment Transaction, and the transactions contemplated by each of the foregoing could divert the attention and time of the Company’s management; the risk of any unexpected costs or expenses resulting from the Asset Sale, the Investment Transaction, and the transactions contemplated by each of the foregoing; the risk that any anticipated distributions of proceeds (whether via a dividend or CVR) may not be declared and paid; the risk of any litigation relating thereto; the uncertainties and variables inherent in business, operating and financial performance, including, among other things, competitive developments and general economic, political, business, industry, regulatory and market conditions, future exchange and interest rates, and changes in tax and other laws, regulations, rates and policies; our ability to continue as a going concern; our ability to maintain the listing of our common stock on Nasdaq; our ability to meet financial covenants with our lenders; our business model and our technology platform; reliance on third party online marketplaces; and other factors discussed in the “Risk Factors” section of our most recent periodic reports filed with the SEC, all of which may be obtained for free on the SEC’s website at www.sec.gov. Although we believe that the expectations reflected in our forward-looking statements are reasonable, we do not know whether our expectations will prove correct. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, even if subsequently made available by us on our website or otherwise. We do not undertake any obligation to update, amend or clarify these forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.
