**WHY YOUR VOTE MATTERS**

The Company's Board of Directors unanimously recommends that stockholders vote "**FOR**" **the election of each of the director nominees named in the Director Election Proposal and** "**FOR**" **each of the following proposals: the Asset Sale Proposal, the Change of Control Proposal, the Related Party Proposal, the Issuance Proposal, the Reverse Stock Split Proposal, the Authorized Stock Increase Proposal and the Adjournment Proposal**.

Following a broad review of strategic alternatives initiated in late 2025, the Company's Board of Directors has unanimously approved two major, concurrent transactions that together provide an actionable path to monetize the Company's portfolio, deliver value to stockholders, and protect the integrity of our brands:

● **$18 Million Sale of Marquee Brand Portfolio** 

The Company has entered into an agreement to sell substantially all of its leading e-commerce brands—including Mueller Living, PurSteam, hOmeLabs, Squatty Potty, Healing Solutions, and Photo Paper Direct—for **$18 million in cash**, prior to certain adjustments as described in our proxy statement filed on June 9, 2026:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Expected **net proceeds of approximately $10.6 million to $14.2 million** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Estimated **$0.85 to $1.14 per share** returned to stockholders

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Anticipated **cash distributions (including CVRs) in Q3 2026** 

● **$7 Million Strategic Investment** <br> Concurrently, Aterian has secured a **$7 million capital investment** to support future strategic opportunities and reposition the Company for growth.

***It***'***s important to know that the strategic investor has waived rights to the dividend of any asset sale proceeds***—***ensuring that stockholders fully benefit from the value generated by the transactions.***

**Forward-Looking Statements**

All statements other than statements of historical facts included in this communication 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 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, all of which are difficult to predict and many of which are beyond our control and 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 at all; 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, shareholders and other business relationships and on its 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 you may obtain for free on the SEC's website at <u>www.sec.gov</u>. 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.
