Insights

Large fund-level sale to issuer and IPO restructuring, neutral signal.

The filing shows an investment fund associated with Hans Kobler selling 6,041,206 Class B Units of Enchanted Rock Holdings, LLC to ERock, Inc. for about $119.9 million, with a matching number of Class B common shares cancelled. This is an internal capital-structure move rather than an open-market trade.

An investment committee at Energy Impact Partners LLC controls voting and investment decisions and its members, including Kobler, disclaim beneficial ownership beyond their pecuniary interests, suggesting a fund-level restructuring more than a personal stake change.

  1. These securities are directly held by Energy Impact Fund (FT-B) LP ("FT-B").

These securities are directly held by EIP Flagship Fund I ER Holdings LLC ("Flagship"). Each of EIF ER Holdings LLC ("EIF ER Holdings", as the sole owner of Flagship), Energy Impact Fund (FT-D) LP ("FT-D", as owner of EIF ER Holdings), Energy Impact Partners LLC ("EIP LLC", as the managing member of EIF ER Holdings and the general partner of FT-D) and the Reporting Person, a nominee to the Issuer's Board of Directors ("Board") (as the managing member of EIP LLC), may also be deemed to be the beneficial owners having shared voting power and shared investment power of the securities held by Flagship. Each of FT-B, EIP LLC (as the general partner of FT-B) and the Reporting Person (as the managing member of EIP LLC) may also be deemed to be the beneficial owners having shared voting power and shared investment power of the securities held by FT-B. Voting and investment decisions with respect to the securities described in this Form 4 are made by the investment committee of EIP LLC, which is comprised of seven individuals, including the Reporting Person, (Continued from footnote 4) Lindsay Luger and Sameer Reddy, each of whom is a nominee to the Issuer's Board. Each member of this investment committee disclaims beneficial ownership of all securities described by Form 4 except to the extent of his or her pecuniary interest therein. The Issuer used approximately $119.9 million of the net proceeds from the closing of the Offering to purchase 6,041,206 Class B Units from Flagship. An equal number of shares of the Issuer's Class B common stock were cancelled in connection with the repurchase of the Class B Units. Shares of the Issuer's Class B common stock ("Class B Common Stock") have no economic value and have one vote per share. One share of Class B Common Stock is issued for each Class B Unit ("Class B Units") of Enchanted Rock Holdings, LLC ("ER Holdings") held. Upon an exchange of Class B Units for shares of the Issuer's Class A common stock ("Class A Common Stock"), an equivalent number of shares of Class B Common Stock held by such holder will be automatically cancelled.

Class B Units financial
"The Issuer used approximately $119.9 million of the net proceeds from the closing of the Offering to purchase 6,041,206 Class B Units from Flagship."
Blocker Mergers financial
"EIF ER Blocker LLC merged with and into the Issuer pursuant to the Blocker Mergers as defined in the Issuer's prospectus."
initial public offering financial
"In connection with the Issuer's initial public offering of Class A common stock, EIF ER Blocker LLC merged with and into the Issuer."
An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.
beneficial owners financial
"Each related entity may also be deemed to be the beneficial owners having shared voting power and shared investment power of the securities held by Flagship and FT-B."
Beneficial owners are the people or entities that actually enjoy the economic benefits and control of shares or other assets, even when legal title is held by someone else such as a broker, custodian or trustee. Investors pay attention because beneficial owners hold the real voting power, receive dividends and can influence strategy and takeover outcomes — like the driver of a car who uses and maintains it while the bank holds the title — so disclosure shows who truly controls and benefits.
pecuniary interest financial
"Each member of this investment committee disclaims beneficial ownership of all securities described by Form 4 except to the extent of his or her pecuniary interest therein."
