Insights

Financial Analyst

TL;DR: Significant open-market purchases increased reported direct ownership to 18.54 million shares across two days; weighted-average prices near $7.01.

The reported acquisitions on 09/23/2025 and 09/24/2025 total 1,001,329 shares bought at weighted averages of $6.9856 and $7.0193. These are non-derivative purchases, implying cash-funded open-market activity rather than option exercises. Reported direct beneficial ownership rose to 18,537,697 shares, and an additional 17,536,369 shares are held indirectly by Hanwha Ocean LLC. The filing includes standard disclaimers about beneficial ownership and group status, limiting affirmative claims about control or intent.

Corporate Governance Expert

TL;DR: Insider purchases are material for disclosure but the filing includes disclaimers about beneficial ownership and group status.

The Form 4 properly discloses two purchase transactions and specifies weighted-average price ranges for each day. The report notes indirect holdings through Hanwha Ocean LLC and contains a disclaimer about beneficial ownership and possible group affiliation. For governance and Section 16 purposes, these disclosures clarify transaction timing and ownership quantities but stop short of asserting control or group membership.
