Houston’s ERock, the company formerly known as Enchanted Rock, is looking to plug into Wall Street in a big way with an initial public offering that could raise roughly $600 million to $642 million. The firm is offering 27.9 million Class A shares at an expected price range of $20 to $23 per share and has applied to list on the New York Stock Exchange under the ticker EROC. Company leaders say the cash infusion would help ramp up Houston manufacturing capacity and turn a hefty contracted backlog into power systems in the field.
Amendment No. 2 to its registration statement dated June 1 shows ERock is offering 27,906,977 shares of Class A common stock and has granted the underwriters a 30‑day option to buy up to 4,186,046 additional shares, moves that could push gross proceeds to roughly $642 million if the top of the range is reached, as laid out in StreetInsider. The filing lists Morgan Stanley and J.P. Morgan as joint lead book‑running managers and names Barclays, BofA Securities, Evercore ISI, Guggenheim, Wolfe | Nomura Alliance and BNP Paribas among the syndicate. The document also outlines expected uses of proceeds, including purchases of Class A units from ER Holdings and repayment of indebtedness, with the balance earmarked for general corporate purposes.
Company Financials and Customers
Per the company’s registration statement filed with the SEC, ERock reported $31.7 million of revenue for the quarter ended March 31, 2026 and a contracted power‑system sales backlog of about $1.3 billion as of the same date. The prospectus says ERock operates roughly 1,000 megawatts across some 400 operational sites and lists major customers including Walmart, H‑E‑B and a 63‑MW resiliency project for Microsoft in San Jose. Those figures are drawn from SEC filings and form the backbone of management’s growth case.
Houston Assembly and Growth Plan
ERock says it assembles proprietary engines and generators at its Titan facility in Houston and is building a Hyperion site that it expects will increase annual assembly capacity toward roughly 1.2 GW by the end of 2026. Local reporting and the company’s release emphasize that Houston’s assembly footprint is central to the plan to convert backlog into revenue; Houston Business Journal earlier covered the firm’s local expansion. The company announced the S‑1 in a press release that described the IPO as a step to “enable energy for a new era.”
Why Investors Are Watching
Market coverage has framed ERock’s offering against surging demand for fast, dispatchable power from data centers and AI infrastructure, a backdrop that helps explain why investors are circling the deal. Bloomberg and Investing.com flagged the company’s strong backlog and said the filing could support a multi‑billion‑dollar valuation as data‑center builds accelerate. Still, analysts and the prospectus both point to execution risk as ERock scales assembly and installs systems on tight timelines.
Structure and Legal Notes
The prospectus describes a UP‑C structure and a Tax Receivable Agreement that could require substantial future cash payments to pre‑IPO owners, a liability the filing explicitly warns could reduce cash available to public shareholders. The SEC filing also highlights recent net losses and cautions that realizing backlog revenue depends on timely execution and supply‑chain stability. Investors should review the “Risk Factors” and “Use of Proceeds” sections of the SEC documents for detailed caveats.
ERock says it will use a portion of net proceeds to buy Class A units from ER Holdings, repay term‑loan debt and support continued expansion of its assembly and service business, with remaining funds for corporate needs. “ERock is enabling energy for a new era,” the company wrote in its announcement via ERock. Market calendars and IPO trackers show the deal could price in early June, with Renaissance Capital listing the week of June 8 as a possible pricing window.
