Eos Energy Director Joseph Nigro Exercises Warrants for 2,773 Shares

What Happened
Joseph Nigro, a director of Eos Energy Enterprises (EOSE), participated in the company’s July 21, 2026 rights offering and related derivative activity. The Form 4 shows he exercised warrants to acquire 2,773 shares by paying $5.48 per share (total cash paid $15,196). The filing also records conversion/disposition entries tied to subscription rights and unit conversions that resulted in an additional 1,217 shares being recorded as acquired (no cash amount reported for that line).

Key Details

• Transaction date: July 21, 2026 (reported on Form 4 filed Aug 6, 2026 — filing was late relative to the usual 2-business-day deadline).
• Paid to acquire common stock: 2,773 shares at $5.48 each = $15,196.
• Additional entries: 2,773 shares listed as disposed (derivative) and 1,217 shares listed as acquired (derivative) at $0.00 in the filing (these reflect conversion of subscription rights into units).
• Shares owned after transaction: not specified in the provided filing summary.
• Footnotes: F1 — the actions stem from conversion of subscription rights in a rights offering; each right was exercisable for a unit of (i) 1 share and (ii) 0.4388 of a warrant. F2 — the warrants became exercisable immediately and expire in 10 years if not exercised.

Context

• These entries reflect participation in a rights offering and subsequent exercise/conversion mechanics, not an open-market buy or sale. Nigro paid cash to exercise certain warrants (a bullish or neutral signal depending on investor view, but not a sale).
• The filing’s zero-dollar derivative lines represent conversion of subscription rights into units and warrants (standard mechanics for rights offerings), and any unexercised warrants will expire without value after their term.
