Item 1.01. Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On June 25, 2026, ASP Isotopes Inc., a Delaware corporation (“ASPI” or the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among ENDRA Life Sciences Inc., a Delaware corporation (“ENDRA”), Noble Africa LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of the Company (“Noble”), Renergen Limited, a company incorporated under the laws of the Republic of South Africa and a direct, wholly-owned subsidiary of the Company (“Renergen”), the Company, and Kruger Merger Sub LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of ENDRA (“Merger Sub”), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Noble (the “Merger”), with Noble surviving the Merger as a direct wholly-owned subsidiary of ENDRA (the “Surviving Company”).

Concurrently with the entry into the Merger Agreement, Noble entered into subscription agreements (“Subscription Agreements”) with the Company and certain investors pursuant to which Noble agreed to sell approximately (i) 4,594,218 Class A Units of Noble (“Class A Units”) and/or pre-funded warrants to purchase Class A Units of Noble (the “Pre-Funded Warrants”) to certain institutional investors and other persons and (ii) 3,054,185 Class B Units of Noble (“Class B Units” and, together with the Class A Units, the “Units”) to the Company, at a price per unit of $6.57 (or $6.57 less the Pre-Funded Warrant exercise price of $0.0001 for the Pre-Funded Warrants), for aggregate gross proceeds to Noble of approximately $50 million (the “Noble Investment”). Pursuant to the Subscription Agreements, the Noble Investment shall close immediately prior to the Merger.

Additionally, prior to the effective time of the Merger (the “Effective Time”), the Company will contribute all of its equity interest in Renergen to Noble in exchange for 55,500,000 of Noble’s Class B Units (the “Contribution”). The shares of Class B Common Stock (as defined below) received by the Company upon conversion of the Class B Units in connection with the Merger will entitle the Company to 10 votes per share on all matters submitted to a vote of the stockholders of ENDRA.

Subject to the terms and conditions of the Merger Agreement, at the Effective Time, all of the units of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and become units of the Surviving Company (“Surviving Company Units”) and ENDRA shall be admitted as the sole member of the Surviving Company as the holder of all Surviving Company Units. Additionally, at the Effective Time, (i) each Class A Unit of Noble outstanding immediately prior to the Effective Time (other than any units of Noble held by ENDRA, Merger Sub, Noble or any of their respective subsidiaries (the “Excluded Company Units”), which shall be automatically cancelled), by virtue of the Merger, shall be converted into the right to receive one share of Class A Common Stock (as defined below), as adjusted for the Reverse Stock Split (as defined below), if applicable, (ii) each Class B Unit of Noble outstanding immediately prior to the Effective Time (other than any Excluded Company Units), by virtue of the Merger, shall be converted into the right to receive one share of Class B Common Stock (as defined below) as adjusted for the Reverse Stock Split (as defined below), if applicable and (iii) each Pre-Funded Warrant that is outstanding and unexercised immediately prior to the Effective Time, will be converted into and become a warrant to purchase Class A Common Stock, and ENDRA shall assume the terms of the Pre-Funded Warrant by which such Pre-Funded Warrant is evidenced (with changes to such documents as the Company and ENDRA mutually agree are appropriate to reflect the substitution of the Pre-Funded Warrant by ENDRA to purchase shares of Class A Common Stock). Pursuant to the A&R Certificate of Incorporation (as defined below), at the Effective Time, each share of ENDRA’s common stock issued and outstanding or held as treasury stock immediately prior to the Effective Time shall, automatically and without further action by any ENDRA stockholder, be reclassified as one share of Class A Common Stock.

Immediately prior to the Effective Time, ENDRA shall file with the Secretary of State of the State of Delaware an amended and restated Certificate of Incorporation (the “A&R Certificate of Incorporation”), pursuant to which ENDRA will be renamed Noble Africa Inc. The A&R Certificate of Incorporation will establish two classes of common stock, consisting of Class A common stock, par value $0.0001 per share (“Class A Common Stock”), and Class B common stock, par value $0.0001 per share (“Class B Common Stock”). The A&R Certificate of Incorporation will authorize 1,000,000,000 shares of Class A Common Stock, 200,000,000 shares of Class B Common Stock, and 50,000,000 shares of preferred stock. Pursuant to the A&R Certificate of Incorporation, the holders of shares of Class A Common Stock and Class B Common Stock shall vote together as one class on all matters, with each holder of Class A Common Stock entitled to one vote for each share of Class A Common Stock held as of the applicable record date and each holder of Class B Common Stock entitled to ten votes for each share of Class B Common Stock held as of the applicable record date. The holders of the Class A Common Stock and Class B Common Stock shall be entitled to share equally, on a per share basis, in any dividends or other distributions declared by ENDRA’s Board of Directors (the “Board”). In the event of involuntary liquidation, dissolution, distribution of assets or winding up of ENDRA, the assets of ENDRA would be divided among and paid ratably to the holders of the Class A Common Stock and Class B Common Stock, treated as a single class. Each share of Class B Common Stock will be convertible into one share of Class A Common Stock at the option of the holder. Additionally, each share of Class B Common Stock shall automatically be converted into one share of Class A Common Stock upon any transfer of such Class B Common Stock other than a Permitted Transfer (as defined in the A&R Certificate of Incorporation), or upon the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock. The A&R Certificate of Incorporation also provides that, without the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting as a separate class, in addition to any other vote required by law or ENDRA’s bylaws or the A&R Certificate of Incorporation, ENDRA shall not, by merger, consolidation, conversion or otherwise, amend, alter, repeal, adopt any inconsistent provision with, or waive Section 4.2 of the A&R Certificate of Incorporation, which pertains to the rights and terms of the Class A Common Stock and the Class B Common Stock, or effect any reclassification of the Class A Common Stock or Class B Common Stock. The A&R Certificate of Incorporation provides that the Board shall be divided into three separate classes, as nearly equal in number as possible, with the first class to hold a term expiring at the first annual meeting of the stockholders following the filing of the A&R Certificate of Incorporation (“Class I”), the second class to hold a term expiring at the second annual meeting of the stockholders following the filing of the A&R Certificate of Incorporation (“Class II”) and the third class to hold a term expiring at the third annual meeting of the stockholders following the filing of the A&R Certificate of Incorporation (“Class III”). At each annual meeting of stockholders beginning with the first annual meeting of stockholders following the filing of the A&R Certificate of Incorporation, successors to the class of directors whose term expires at that annual meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders to be held in the third year following the year of their election.

Immediately after the Effective Time, the Board is expected to consist of seven directors, of which (i) one is anticipated to be the Chief Executive Officer of the Surviving Company (the “CEO Director”), (ii) five are to be non-executive directors designated solely by Noble (the “Noble Directors”) and (iii) one is to be a non-executive director designated solely by ENDRA (the “ENDRA Director”). Class I shall be comprised of two of the Noble Directors, Class II shall be comprised of one of the Noble Directors and the ENDRA Director and Class III shall be comprised of two of the Noble Directors and the CEO Director.

Pursuant to the Merger Agreement, on the closing date of the Merger prior to the Effective Time, subject to the prior receipt of stockholder approval, ENDRA may implement a reverse stock split (the “Reverse Stock Split”) for the purpose of maintaining compliance with Nasdaq listing standards, at a reverse split ratio approved by the Board.

In connection with the Merger, ENDRA plans to seek the approval of its stockholders at a special meeting (the “Special Meeting”) of, among other things, (i) the issuance of the shares of Class A Common Stock and Class B Common Stock as the Merger Consideration, (ii) the Reverse Stock Split, (iii) the adoption of a new incentive equity plan, and (iv) the A&R Certificate of Incorporation (all such voting proposals in this paragraph, the “ENDRA Stockholder Matters”).

The Merger Agreement includes customary representations, warranties and covenants, including, among others, covenants relating to (i) ENDRA’s obtaining the approval of its stockholders of the ENDRA Stockholder Matters, (ii) ENDRA’s non-solicitation of alternative acquisition proposals, (iii) the conduct of their respective businesses during the period between the date of signing the Merger Agreement and the Closing, (iv) ENDRA’s filing with the U.S. Securities and Exchange Commission (the “SEC”) and causing to become effective a registration statement on Form S-4 to register the shares of the Class A Common Stock and Class B Common Stock to be issued in connection with the Merger (the “Registration Statement”), and (v) ENDRA’s preparing and submitting to Nasdaq an initial listing application or notification form for notifying Nasdaq of the change in its name and the listing of the Class A Common Stock and Class B Common Stock to be issued as Merger Consideration. The representations and warranties will not survive Closing, except with respect to intentional fraud, and there will be no escrow or price adjustments for any breaches of the representations, warranties, and covenants of any party following Closing.

Each of ENDRA, Renergen, the Company and Noble has agreed, subject to certain exceptions with respect to unsolicited proposals, not to directly or indirectly solicit competing acquisition proposals or to enter into discussions concerning, or provide confidential information in connection with, any unsolicited alternative acquisition proposals. However, ENDRA may provide information to any person who has made an unsolicited, bona fide written acquisition proposal, if such proposal is made after the date of the Merger Agreement, ENDRA’s Board determines in good faith, after consultation with outside legal counsel, (i) that such proposal would reasonably be expected to be a superior proposal and (ii) that failure to provide information in connection with such proposal would reasonably be expected to be inconsistent with its fiduciary duties to ENDRA and ENDRA’s stockholders under Delaware law, and such person executes and delivers a confidentiality agreement to ENDRA containing substantially the same terms and conditions as the confidentiality agreement between ENDRA and the Company.

Consummation of the Merger is subject to certain closing conditions, including the accuracy of the representations and warranties of the other parties, subject to applicable materiality standards, the approval of the ENDRA Stockholder Matters, the Registration Statement being declared effective by the SEC, the approval for listing on Nasdaq (or any other public stock market or exchange in the United States as may be agreed by Noble and ENDRA) of the Class A Common Stock and Class B Common Stock to be issued as the Merger Consideration, the receipt by Noble of the proceeds of the Noble Investment, Noble’s receipt of a written consent of the U.S. Internal Development Finance Corporation (formerly known as the Overseas Private Investment Corporation) (“OPIC”) as required under that certain Finance Agreement by and between OPIC and a subsidiary of Renergen, ENDRA’s having an amount of cash equal to or greater than $3.8 million, the Company having effected the Contribution, and the performance in all material respects by the applicable parties of their agreements, obligations and covenants under the Merger Agreement required to be performed on or prior to the date of the Closing.

The Merger Agreement contains certain termination rights of each of ENDRA and Noble. The Merger Agreement may be terminated at any time prior to Closing by mutual written agreement between ENDRA and Noble or by either party if Closing shall not have occurred by December 24, 2026. Either ENDRA or Noble may also terminate the Merger Agreement if the representations or warranties of the other party were inaccurate as of the date of the Merger Agreement or become inaccurate thereafter due to a breach of a covenant or agreement of that party prior to Closing, or if the ENDRA Stockholder Matters are not approved by the ENDRA stockholders at the Special Meeting.

Concurrently with the Closing, ENDRA will enter into a registration rights agreement and certain business continuity agreements with the Company, including a master transaction agreement, shared services agreement, employee matters agreement and tax sharing agreement. The master transaction agreement will contain key provisions relating to the conduct of future transactions and govern the ongoing relationship between the Company and ENDRA after the Closing, including sales of helium, certain indemnification obligations and a requirement for ENDRA to maintain the same auditor and fiscal year as the Company for so long as the Company is required to consolidate the financial statements of the Company under GAAP. Under the shared services and employee matters agreements, the Company will provide certain administrative services to ENDRA in exchange for a service fee equal to the operating cost plus a margin.

In connection with ENDRA’s entry into the Merger Agreement, ENDRA stockholders that participated in ENDRA’s October 15, 2025 private placement (the “October 2025 Private Placement”) waived their right to cause ENDRA to repurchase warrants issued in the October 2025 Private Placement following a change of control of ENDRA for their Black-Scholes value.

At or prior to the Closing, the Company, ASPI South Africa Proprietary Limited, a wholly owned subsidiary of the Company (“ASPI SA”), and Renergen, shall enter into the fifth addendum to that certain ASPI Term Loan Facility, dated May 19, 2025, by and between the Company, ASPI SA and Renergen, pursuant to which the Company may provide loans to Renergen up to $200 million.

In connection with the Noble Investment, Noble entered into Subscription Agreements with certain of the Company’s directors and officers, pursuant to which Noble agreed to sell to the following directors and officers Class A Units of Noble in the amounts and for the aggregate purchase prices set forth below:
