Item 8.01

Other Events.

On March 23, 2026, Outlook Therapeutics, Inc. (the “Company”) commenced a best-efforts public offering (the “Offering”) of its common stock and accompanying warrants to purchase shares of common stock. H.C. Wainwright & Co., LLC acted as exclusive placement agent (the “Placement Agent”) in connection with the Offering. In the Offering, the Company agreed to issue and sell (i) 20,000,000 shares of the Company's common stock, par value $0.01 per share (the “Common Stock”), and (ii) accompanying warrants to purchase up to an aggregate of 20,000,000 shares of Common Stock (the “Warrants”), with each share of Common Stock sold in the Offering accompanied by a Warrant to purchase one share of Common Stock. The combined public offering price of each share of Common Stock and accompanying Warrant is $0.25. The Company has entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain of the investors in the Offering. The Offering closed on March 25, 2026.

The gross proceeds from the Offering, excluding the proceeds, if any, from the exercise of the Warrants and the Placement Agent Warrants (as defined below), were approximately $5.0 million, before deducting the placement agent fees and estimated offering expenses payable by the Company. The net proceeds from the Offering, after deducting placement agent fees and estimated offering expenses, were approximately $4.0 million.

Each Warrant has an initial exercise price per share of $0.25, subject to certain customary adjustments for recapitalizations, stock splits and similar actions. The Warrants are exercisable immediately and will expire five years from the date of issuance. A holder (together with its affiliates and other attribution parties) may not exercise any portion of a Warrant to the extent that immediately after giving effect to such exercise the holder would own more than 4.99% or 9.99%, as applicable, of the Company's outstanding Common Stock immediately after exercise, which percentage may be changed at the holder's election upon 61 days' notice to the Company subject to the terms of the Warrants.

Pursuant to the Purchase Agreement, the Company agreed not to offer for sale, contract to sell, or sell any shares of Common Stock or any securities convertible into, or exercisable or exchangeable for, shares of Common Stock, subject to certain customary exceptions set forth therein. In addition, the Company has agreed not to effect or enter into an agreement to effect any issuance of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until the one-year anniversary of the closing date of the Offering, subject to certain exceptions set forth therein.

Pursuant to an engagement letter (the “Engagement Letter”) dated March 11, 2026 with the Placement Agent, the Company has agreed to pay to the Placement Agent in connection with the Offering (i) a cash fee equal to 7.0% of the aggregate gross proceeds raised in the Offering, (ii) a management fee equal to 1.0% of the aggregate gross proceeds raised in the Offering, (iii) up to $100,000 for fees and expenses of the Placement Agent’s counsel, (iv) a non-accountable expense allowance of $10,000, and (v) up to $15,950 for clearing expenses. In addition, under the Engagement Letter the Company issued to the Placement Agent (or its designees) warrants to purchase 1,400,000 shares of Common Stock, which is equal to 7.0% of the aggregate number of shares of Common Stock sold in the Offering (the “Placement Agent Warrants”). Each Placement Agent Warrant has an exercise price equal to $0.3125, which is 125% of the combined public offering price per share of Common Stock and accompanying Warrant. The Placement Agent Warrants are exercisable immediately and will expire five years from the commencement of sales of the securities in the Offering.

The Offering is being made pursuant to the Company's effective registration statement on Form S-3 (Registration Statement No. 333-278340) previously filed with the Securities and Exchange Commission (the “SEC”) on March 28, 2024 and which became effective on April 5, 2024, and a prospectus supplement thereunder.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Purchase Agreement were made only for the purposes of the Purchase Agreement and as of specific dates and were solely for the benefit of the parties to the Purchase Agreement.

The foregoing descriptions of the terms of the Purchase Agreement, the Warrants, and the Placement Agent Warrants are each qualified in their entirety by reference to the Purchase Agreement, the form of Warrant, and the form of Placement Agent Warrant, respectively, which are attached as Exhibit 10.1, Exhibit 4.1 and Exhibit 4.2 hereto, respectively, and incorporated by reference herein.

A copy of the legal opinion of Cooley LLP relating to the validity of the issuance and sale of the securities in the Offering is attached as Exhibit 5.1 hereto.
