| Item 1.01 | Entry into a Material Definitive Agreement. |
On November 20, 2025, Inhibikase Therapeutics, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies LLC, BofA Securities, Inc. and Cantor Fitzgerald & Co., as representatives of the several underwriters listed on Schedule A thereto (collectively, the “Underwriters”), relating to an underwritten public offering (the “Offering”) of (i) 46,091,739 shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”) and (ii) in lieu of Common Stock to certain investors, pre-funded warrants to purchase up to an aggregate of 22,873,779 shares of Common Stock (the “Pre-Funded Warrants” and the Common Stock issuable upon exercise of the Pre-Funded Warrants, the “Warrant Shares”). The Company also granted the underwriters a 30-day option to purchase up to an additional 10,344,827 shares of Common Stock at the public offering price, less underwriting discounts and commissions. All of the Shares and the Pre-Funded Warrants in the Offering were sold by the Company. Each Share was offered and sold at an offering price of $1.45, and each Pre-Funded Warrant was offered and sold at an offering price of $1.449, which is equal to the offering price per share of Common Stock less the $0.001 exercise price of each Pre-Funded Warrant. The Offering is expected to close on November 24, 2025, subject to customary closing conditions.
Each Pre-Funded Warrant has an initial exercise price per share of $0.001, subject to certain adjustments. The Pre-Funded Warrants are exercisable immediately and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.
Under the Pre-Funded Warrants, the Company may not effect the exercise of any Pre-Funded Warrant, and a holder will not be entitled to exercise any portion of any Pre-Funded Warrant (i) if immediately prior to the exercise, holder (together with its affiliates), beneficially own an aggregate number of shares of Common Stock greater than 4.99% or 9.99%, as applicable (the “Maximum Percentage”) of the total number of issued and outstanding shares of Common Stock of the Company without taking into account any Warrant Shares, or (ii) to the extent that immediately following the exercise, holder (together with its affiliates) would beneficially own in excess of the Maximum Percentage of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of such shares of Common Stock, which such percentage may be changed at the holder’s election to a higher or lower percentage not in excess of 19.99% upon 61 days’ notice to the Company.
The Company estimates that the net proceeds from the Offering will be approximately $93.6 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, or $107.7 million, if the underwriters exercise their option in full.
The Offering was made pursuant to a shelf registration statement on Form S-3 (File No. 333-288213) as filed with the U.S. Securities and Exchange Commission (“SEC”) on June 20, 2025 and declared effective on June 27, 2025, as supplemented by a final prospectus supplement dated November 20, 2025, filed on November 21, 2025.
The Underwriting Agreement contains customary representations, warranties, covenants, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, and other obligations of the parties. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties. The foregoing is only a brief description of the terms of the Underwriting Agreement, does not purport to be a complete statement of the rights and obligations of the parties under the Underwriting Agreement and the transactions contemplated thereby, and is qualified in its entirety by reference to the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.
The foregoing is only a brief description of the terms of the form of Pre-Funded Warrant, does not purport to be a complete statement of the rights and obligations of the parties thereto and the transactions contemplated thereby, and is qualified in its entirety by reference to the form of Pre-Funded Warrant that is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.
A copy of the legal opinion of Goodwin Procter LLP relating to the issuance and sale of the Shares and the Pre-Funded Warrants in the Offering is filed as Exhibit 5.1 to this Current Report on Form 8-K and is filed with reference to, and is incorporated herein by reference.
| Item 8.01 | Other Events. |
Effective November 20, 2025, the Company and the holders of all of the outstanding Series A-1 Warrants to Purchase Common Stock or Pre-Funded Warrants (each, a “Series A-1 Warrant”) and outstanding Series B-1 Warrants to Purchase Common Stock or Pre-Funded Warrants (each, a “Series B-1 Warrant”) issued on October 21, 2024, amended the terms of the Series A-1 Warrants (the “Amendment to Series A-1 Warrant”) and the Series B-1 Warrants (the “Amendment to Series B-1 Warrant”) to reflect the Company’s plan to advance IKT-001 to a global pivotal Phase 3 clinical trial in PAH.
The descriptions of the Amendment to Series A-1 Warrant and the Amendment to Series B-1 Warrant do not purport to be complete and are qualified in their entirety by the terms and conditions of the Amendment to Series A-1 Warrant and the Amendment to Series B-1 Warrant. Copies of the form of the Amendment to Series A-1 Warrant and the form of the Amendment to Series B-1 Warrant are attached hereto as Exhibits 4.2 and 4.3, respectively, and are incorporated herein by reference.
