EIF ER Holdings LLC 4

What Happened

Energy Impact Partners LLC (reported as a 10% owner/beneficial owner group) was involved in IPO-related transactions on June 11, 2026. As part of blocker mergers tied to ERock’s IPO, FT-B (an EIP-related fund) received 19,350,897 shares of ERock Class A common stock and approximately $27.8 million in cash as merger consideration. Separately, 6,041,206 Class B Units held by a related EIP entity (Flagship) were repurchased/cancelled by the issuer; the filing treats those repurchases as dispositions (one entry is coded as a derivative sale).

No per‑share price is reported for these entries (N/A). The issuer used approximately $119.9 million of IPO net proceeds to repurchase 6,041,206 Class B Units from Flagship (footnotes).

• Shares/units after transactions: FT‑B directly holds 19,350,897 Class A shares (per footnote). Flagship’s 6,041,206 Class B Units were repurchased/cancelled.
• Notable structure/footnotes: Class B common stock has no economic value and is issued one‑for‑one with Class B Units; Class B Units are exchangeable one‑for‑one into Class A shares. The transactions arise from corporate restructuring in connection with the IPO (Blocker Mergers and unit repurchase), not a routine open‑market investment.
• Filing timeliness: Form filed June 15, 2026 for June 11 transactions (no late‑filing flag shown in the record provided).

Context

• This is institutional/placement activity tied to the company’s IPO and corporate reorganization (blocker mergers and repurchase of Class B Units), not a typical insider buy/sell by an individual executive.
• Benefit and voting attribution: Several related entities and individuals (EIP LLC, FT‑B, Flagship and nominee directors) are disclosed as sharing beneficial ownership or voting/investment power per the footnotes; investment decisions are made by EIP’s investment committee.
• For retail investors: these entries reflect IPO‑related corporate transactions and fund restructurings (receiving IPO shares and cash, and selling/ cancelling Class B Units), not a straightforward market sentiment signal like an open‑market purchase by an executive.
