Purpose of Transaction (Item 4)
Funicular Funds, LP
Item 4 is hereby amended to add the following: On November 17, 2025, with the prior authorization of Cede & Co. as contributory, Funicular Funds, LP filed a petition with the Grand Court of the Cayman Islands Financial Services Division, In the Matter of Section 94 of the Companies Act (2025 Revision) and In the Matter of Nabors Energy Transition Corp. II. The petition seeks the appointment of court-supervised liquidators and the commencement of a just and equitable winding up process on the grounds that the substratum of the Issuer has failed and the Reporting Persons have justifiably lost trust and confidence in the management of the Issuer.Item 4 of the SCHEDULE 13D/A filed 2025-11-19
ATG Fund II LLC
The Reporting Persons acquired the position in the Class A Ordinary Shares of the Issuer in the belief that the Class A Ordinary Shares represented an attractive investment opportunity. The acquisitions of the Class A Ordinary Shares were made in the ordinary course of the Reporting Persons' investment activities and are currently held for investment purposes. The Reporting Person believes that Issuer's apparent intention to redeem or liquidate securities of the Issuer while Nabors Energy Transition Sponsor II LLC, the sponsor of the issuer (the "Sponsor"), will retain for itself certain valuable assets or consideration received in connection with the Issuer's prior failed transaction is improper and inconsistent with the Issuer's and the Sponsor's fiduciary and contractual obligations to the Issuer's shareholders. In the Reporting Person's view, any termination fees, rights, claims, or other contingent or actual assets generated during the Issuer's business combination process belong to the Issuer and must be allocated pro rata among all shareholders of the Issuer. The Reporting Person considers any attempt by the Sponsor to appropriate such assets for its own benefit-while shareholders of the Issuer are limited to the cash held in the trust account-to be unacceptable.Item 4 of the SCHEDULE 13D filed 2025-11-28

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
