Insights

TL;DR: Reporting group holds a large, disclosed block (42.2%) after internal reorganizations; amendment increases public transparency about derivative exposure.

The filing documents a substantial beneficial position of 70,470,018 shares (42.2%) and records internal corporate reorganizations finalized on August 11, 2025. These disclosures clarify which legal entities now hold the stake and who may be deemed to share beneficial ownership. The Schedule 13D amendment also supplements Item 4 and Item 6 to describe new option transactions, improving investor visibility into arrangements that create economic exposure separate from the disclosed beneficial ownership.

TL;DR: Atlas entered into European-style call spread transactions with three banks for capped economic exposure up to 1,111,111 shares each, exercisable in 40 tranches.

The amendment describes call spread option transactions executed on August 11, 2025 with Credit Agricole, Societe Generale and Natixis.

The arrangements are exercisable in 40 separate tranches with staggered expirations and may be settled in Common Shares or cash.
