Another energy company in Houston is going public amid a flurry of energy IPOs.

Houston-based ERock Inc., which specializes in utility-grade onsite microgrid systems for data centers and other customers, has filed paperwork with the U.S. Securities and Exchange Commission (SEC) to sell its shares on the New York Stock Exchange.

The ERock filing follows the recent $1.9 billion IPO of Houston-based Fervo Energy, a provider of geothermal power that’s now valued at $7.7 billion.

Another Houston energy company, EagleRock Land, just went public in a $320 million IPO that values the company at $3 billion. EagleRock owns or controls about 236,000 acres in the Permian Basin, earning money from royalties, fees, easements, water services and other revenue streams tied to drilling on its land.

According to Barron’s, more than a dozen energy and energy-related companies in the U.S. have gone public since the beginning of 2025, with the bulk of the IPOs happening this year.

ERock’s SEC filing doesn’t identify the per-share pricing range for the IPO or the number of Class A shares to be offered. ERock is a portfolio company of Energy Impact Partners, a New York City-based venture capital and private equity firm that invests in energy companies.

The company previously did business as Enchanted Rock. ERock Inc., formed in January, will function as a holding company that controls predecessor company ER Holdings Ltd.

In 2025, ERock generated revenue of $183.1 million, up 42.5 percent from the previous year, according to the IPO filing. It recorded a net loss of $59 million last year.

As of March 31, ERock boasted a sales backlog of nearly $1.3 billion, up 779 percent on a year-over-year basis. The company attributes most of that increase to greater demand from data centers.

The company primarily serves the power needs of data centers, utilities, industrial facilities, and commercial buildings. Its biggest markets are Texas and California.

“Several U.S. markets, such as Texas and California, face especially acute reliability risks,” ERock says in the SEC filing. “Texas already shows rapid load-growth pressures tied to data centers and industrial expansion, while California faces grid congestion, long interconnection queues, and above-average vulnerability to extreme heat- and weather-driven outages.”

Since its founding in 2018, ERock has installed microgrid systems at more than 400 sites with a capacity of about 1,000 megawatts. Customers include ComEd, Foxconn, H-E-B, Microsoft and Walmart.

By the end of this year, the company plans to expand its production of microgrid systems to a capacity of about 1.2 gigawatts with the opening of its Hyperion facility in Houston.

John Carrington leads ERock as CEO. He joined ER Holdings last year as chairman and CEO. Carrington previously was CEO of Houston-based Stem, a public company that offers AI-enabled clean energy software and services. Earlier, he spent 16 years at General Electric.

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Breaking news: ExxonMobil's HQ officially changed to Houston

now in HOU

As of this month, ExxonMobil's headquarters is officially Houston, according to a recent filing.

ExxonMobil's company page on the United States Securities and Exchange Commission now lists its new Houston-area address — 22777 Springwoods Village Parkway in Spring. While the ExxonMobil's site still lists it's Irving, Texas, address, the SEC filing dated July 5 marks a significant step toward the HQ move that Exxon originally announced in early 2022.

In the initial announcement, the company disclosed that the move, which will combine its chemical and refining divisions, will be completed by 2023. ExxonMobil’s Spring office was opened by former CEO Rex Tillerson in 2014.

With the relocation announcement, ExxonMobil became Houston’s 25th Fortune 500 headquarters, the third highest concentration in the country, after New York and Chicago, per the Greater Houston Partnership. It's slated to be the largest Fortune 500 company to be headquartered in the Houston region, ranking No. 10 in the 2021 listing based on $181.5 billion revenues in 2020.

“ExxonMobil’s move further solidifies Houston’s position as the Energy Capital of the World," the Greater Houston Partnership noted in a January 31 statement. "ExxonMobil is a key participant in our Houston Energy Transition Initiative, and we look forward to working with the company as we continue to position Houston to lead the energy transition to a low-carbon future."

Since the announcement, ExxonMobil has grown its Houston presence by signing on as a founding partner at the Ion, a Midtown Houston 266,000-square-foot building developed and managed by Rice Management Company, last summer. The company joins existing Ion founding partners Aramco, Chevron Technology Ventures, Baker Botts, and Microsoft, as well as affiliate partners bp and Intel. The company joins the Ion "to help develop solutions for the world’s emerging energy issues," per the June 13 news release.

“ExxonMobil has been a leader in energy technology for over a century. Collaboration is essential to both augment our capabilities and accelerate the development of scalable solutions,” said Linda DuCharme, president of ExxonMobil Technology and Engineering Company, in the release. “Our partnership with The Ion will enable us to tap into the extraordinary talent in Houston.”

New study shows Houston is still feeling effects of 2014-16 oil crash

lasting impact

A new study from Rice’s Kinder Institute shows that Houston is still feeling the economic effects of the 2014-2016 oil crash, more than a decade later.

Though Houston, nicknamed the Energy Capital of the World, has continued to grow over the time period, the city has still fallen behind other comparable metropolitan areas in earnings and job creation, according to the research. The report is one part of a three-part series that will take a look at regional economic mobility and suggest ideas to expand opportunity.

“When you look at what’s happened in other locations, we’re losing ground,” Flávio Cunha, director of the Center for Economic Mobility at Rice’s Kinder Institute for Urban Research, said in a release. “Our economy is growing, but it’s no longer growing at the rate it used to.”

Global oil prices fell 70 percent between 2014 and 2016, the report said, marking one of the three largest declines since World War II and the longest-lasting downturn since 1986. The report excluded pandemic-related gaps, and it mentions 2017’s Hurricane Harvey as a possible indicator that economic growth stalled after the 2014-2016 oil price crash recovery.

To understand the long-term impact of the crash, researchers compared Houston’s economic performance with 54 metropolitan areas like San Antonio, Pittsburgh and others with less dependence on the energy industry.

Some of the key findings in the report included:

Job creation: In 2019, Houston had approximately 240,000 fewer private-sector jobs than similar cities. Employment was 15 percent lower in goods-producing industries and 4 percent lower in the services industries than the control group.
Income shifts: Income per resident was 13 percent lower compared to the peer group. Workers who remained employed earned 10 percent less between 2015 and 2019 than in other metros. The 13 percent drop in income equates to roughly $76 billion a year in forgone income, or $10,700 per resident per year in 2025 dollars. The decline was a trend across every age group, education level and sex.
Population changes: The rate of people moving to Houston slowed, rather than a surge of people leaving.
Hiring changes: Hiring fell sharply for young workers ages 19-24.

Cunha says the most surprising finding was that these trends persisted a decade later. According to the report, by 2024, Houston’s wages and income per resident remained about a fifth and a sixth below those in peer cities, and jobs per resident had continued to lose ground.

“What really surprises me is not that there was this change. It’s that this change has been long-lasting,” he added. “We followed it up to 2024, and we still don’t detect that the economy has recovered from that one shock.”

2 fast-growing energy cos. are finalists for Houston Scaleup of the Year

Meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of InnovationMap's 2026 Houston Innovation Awards, the Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award, two of which are in the energy transition sector.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A last month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Oxy inks long-term agreements for 2M tons of CO2 capture, transport

carbon contracts

Houston-based Occidental has made two long-term agreements that will expand its carbon management business in the Delaware Basin and the Permian Basin.

Oxy announced Nov. 9 that it has signed agreements with two unnamed project developers to capture and transport approximately 2 million metric tons of CO2 from their existing and new natural gas processing facilities in the Delaware Basin in West Texas annually. The CO2 will be transported for use in Oxy's enhanced oil recovery (EOR) operations in the Permian Basin.

“Securing reliable, long-term sources of CO2 supports Occidental’s advanced recovery strategy to extend the productive life of existing fields and enhance recovery across our conventional and unconventional resource base,” Vishal Gupta, president and general manager of EOR Ventures at Occidental, said in a news release. “The projects, once operational, will help diversify our CO2 supply, improve access to cost-effective resources and create infrastructure that can connect additional carbon capture projects over time. Federal 45Q incentives are an important support for these investments.”

According to the release, the projects have the potential to expand to handle up to 4 million metric tons of C02 per year combined. The first shipments to Oxy are expected in 2029. The unnamed developers will fund and build the infrastructure to capture, transport and deliver the CO2 to Oxy, the company shared in the release.

Additionally, the agreement stipulates that the projects will also include the build-out of nearly 100 miles of new CO2 pipeline infrastructure. The new pipeline is planned to connect with the existing CO2 pipeline network in the Permian Basin. Oxy adds that the pipelines are being designed to handle additional future capacity to "support future conventional and unconventional recovery opportunities" of CO2.

Oxy uses the EOR process to inject stored CO2 back into a producing oil fields to boost the site's performance. The recycled CO2 displaces trapped oil and gas and is then secured in the reservoir. Oxy says that EOR combined with Direct Air Capture (DAC) technology "remove[s] an amount of CO2 equivalent to that emitted during the production and consumption of [its] products."

Oxy subsidiary 1PointFive is developing a $1.3 billion DAC project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year. After a component delay, 1PointFive shared in May that it would ramp up operations at the project throughout 2026.
