The filing shows **Hanwha Aerospace Co., Ltd.** making three open‑market purchases of **NextDecade Corp** common stock on 11/17/2025, 11/18/2025, and 11/19/2025. The purchases total **1,064,424** shares at weighted average prices of $5.8683, $5.9247, and $6.0362, within stated price ranges around each average. After these transactions, the reporting person holds **20,898,622** shares directly and **17,536,369** shares indirectly through **Hanwha Ocean LLC**.

The disclosure describes these as acquisitions coded "P" (open‑market or private purchases) and reports no derivative securities in Table II. The footnotes clarify that the reported prices are weighted averages, that detailed trade‑by‑trade information is available on request, and that Hanwha Aerospace may be deemed to beneficially own the shares held by Hanwha Ocean LLC, while expressly disclaiming beneficial ownership beyond its pecuniary interest. The remarks also note that the reporting person may be deemed part of a Section 13(d) "group" owning more than 10% of the common stock, while disclaiming membership in any such group.

This matters because it documents a meaningful increase in an already large position and confirms that a major holder remains a net buyer over this short window. Key items to monitor include any future Forms 4 that change the **20,898,622** direct or **17,536,369** indirect share counts, and any later Schedule 13D/13G or group‑related filings that clarify the ownership structure or group status over time.
