Eos Energy (EOSE) Director Marian Walters Exercises Warrants/Rights

What Happened

• Marian Walters, a director of Eos Energy Enterprises (EOSE), converted subscription rights from a rights offering that closed on July 21, 2026. As part of that conversion she acquired 11,407 shares by paying $5.48 per share (total cash paid $62,510).
• The filing also shows conversion/disposition entries tied to the subscription rights and the related warrants (some recorded at $0 as derivative transactions). The units issued in the rights offering consisted of one common share plus 0.4388 of a warrant per unit.

Key Details

• Transaction date: July 21, 2026; Form 4 filed: August 6, 2026 (filed late relative to the typical 2-business-day rule).
• Paid for shares: 11,407 shares @ $5.48 each = $62,510 cash outlay.
• Derivative activity: entries show 11,407 derivative units disposed at $0 (conversion of rights) and 5,005 derivative units acquired at $0 (warrants/units allocation).
• Shares of record: holdings are reported as held by David Walters and Marian Walters as trustees of the D. and M. Walters Family Trust (per footnote).
• Not a sale: this was a conversion/exercise of rights and receipt of warrants, not an open-market sale.

Context

• The rights offering units included warrants that became exercisable immediately after the offering closed; those warrants carry an exercise price of $5.48 and expire in 10 years (if not exercised they will be worthless).
• This is a purchase/conversion (acquisition) rather than a sale, which is generally more informative to investors than routine sales; no immediate market sale of acquired shares was reported.
• The Form 4 was filed on Aug 6 for the July 21 transactions — a late filing, which is a disclosure/timeliness issue but does not change the substance of the transactions.
