Aether Holdings, Inc.

Item 1.01 Entry into a Material Definitive Agreement. On May 13, 2026, Aether Holdings, Inc., a Delaware corporation (the “Company”), entered into a note purchase agreement (the “Purchase Agreement”) with Streeterville Capital, LLC, a Utah limited liability company (the “Lender”), pursuant to which the Company issued and sold to the Lender a secured promissory note in the original principal amount of $3,240,000.00 (the “Note”). The Note carries an original issue discount of $240,000.00, which is included in the original principal amount of the Note, and the Company agreed to pay $30,000.00 to the Lender for legal fees, accounting costs, due diligence and other transaction expenses, which amount was deducted from the purchase price funded to the Company at closing. The purchase price for the Note was $3,000,000.00. The Note matures eighteen (18) months after the Purchase Price Date (as defined in the Note) and bears interest on the outstanding balance at a rate of 8.0% per annum, compounded daily. The Company may prepay the Note in full at any time by paying 110% of the outstanding balance. If the Note remains outstanding on the six-month anniversary of the Purchase Price Date, a one-time monitoring fee will be added to the outstanding balance, subject to the forgiveness provisions set forth in the Note. Beginning on the six-month anniversary of the Purchase Price Date, the Lender may redeem up to $250,000.00 of the outstanding balance per calendar month. Upon the occurrence of a Limited Redemption Event (as defined in the Note), the Lender may also exercise limited redemptions up to the Maximum Limited Redemption Amount (as defined in the Note), with each redemption payable in cash within three trading days of the applicable redemption notice. The Company’s obligations under the Note and the other transaction documents are secured by (i) a first-position security interest in substantially all of the Company’s assets pursuant to a Security Agreement, (ii) a first-position security interest in the Company’s intellectual property pursuant to an Intellectual Property Security Agreement, and (iii) a Guaranty by the Company’s subsidiaries. The Purchase Agreement requires the Company to refrain, without the Lender’s prior written consent, from making Restricted Issuances (as defined in the Purchase Agreement), granting liens on assets, or selling, transferring or issuing equity or voting rights in its subsidiaries. The Company also agreed not to permit its subsidiaries to incur debt other than in the ordinary course of business. The Purchase Agreement also prohibits the Company from entering into agreements that would restrict the Company from entering into a variable rate transaction with the Lender or from issuing securities to the Lender or its affiliates. In addition, so long as the Note is outstanding, the Purchase Agreement contains a most favored nation provision with respect to more favorable economic terms granted to future debt holders. Upon the occurrence of a Trigger Event under the Note, the Lender may increase the outstanding balance by applying a 15% Trigger Effect for each Major Trigger Event or a 5% Trigger Effect for each Minor Trigger Event, in each case subject to the limitations set forth in the Note. Trigger Events include, among other things, payment defaults; bankruptcy and insolvency events; entry into or consummation of a Fundamental Transaction without repayment of the Note in full; breaches of covenants in Section 4 of the Purchase Agreement or other material obligations under the transaction documents; materially false or misleading representations; a reverse stock split without twenty trading days’ prior notice to the Lender; certain money judgments in excess of $500,000.00; and certain breaches of other agreements with the Lender or its affiliates. If a Trigger Event is not cured within the applicable five-trading-day cure period, or automatically upon the occurrence of certain insolvency-related Trigger Events, the Note may become immediately due and payable at the Mandatory Default Amount, and default interest may accrue at 15% per annum. 2 The Purchase Agreement provides specified exceptions to certain covenant restrictions, including exceptions for a commercial mortgage on the Company’s New York property up to $2,000,000.00 and a working capital line of credit up to $1,000,000.00, in each case subject to the limits set forth in the transaction documents. The Purchase Agreement and the related transaction documents contain arbitration provisions governed by Utah law and provide the Lender with specified equitable remedies, including injunctive relief and specific performance, in certain circumstances.
