going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.

Houston-based Fervo Energy bumps up IPO target to $1.82 billion

IPO update

Houston-based geothermal power company Fervo Energy is now eyeing an IPO that would raise $1.75 billion to $1.82 billion, up from the previous target of $1.33 billion.

In paperwork filed Monday, May 11 with the U.S. Securities and Exchange Commission, Fervo says it plans to sell 70 million shares of Class A common stock at $25 to $26 per share.

In addition, Fervo expects to grant underwriters 30-day options to buy up to 8.33 million additional shares of Class A common stock. This could raise nearly $200 million.

When it announced the IPO on May 4, Fervo aimed to sell 55.56 million shares at $21 to $24 per share, which would have raised $1.17 billion to $1.33 billion. The initial valuation target was $6.5 billion.

A date for the IPO hasn’t been scheduled. Fervo’s stock will be listed on Nasdaq under the ticker symbol FRVO.

Fervo, founded in 2017, has attracted about $1.5 billion in funding from investors such as Bill Gates-founded Breakthrough Energy Ventures, Google, Mitsubishi Heavy Industries, Devon Energy (which is moving its headquarters to Houston), Tesla co-founder JB Straubel, CalSTRS, Liberty Mutual Investments, AllianceBernstein, JPMorgan, Bank of America and Sumitomo Mitsui Trust Bank.

Fervo’s marquee project is Cape Station in Beaver County, Utah, the world’s largest EGS (enhanced geothermal system) project. The first phase will deliver 100 megawatts of baseload clean power, with the second phase adding another 400 megawatts. The site can accommodate 2 gigawatts of geothermal energy. Fervo holds more than 595,000 leased acres for potential expansion.

Cape Station has secured power purchase agreements for the entire 500-megawatt capacity. Customers include Houston-based Shell Energy North America and Southern California Edison.

Houston geothermal unicorn Fervo officially files for IPO

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.

Financiers plan to launch a Texas-based stock exchange

A group of financial firms and investors is planning to launch a Texas-based private market stock exchange and offer traders an alternative to the New York Stock Exchange and Nasdaq.

The group, which includes BlackRock, Citadel Securities and about two dozen investors, raised approximately $120 million of capital to create the Texas Stock Exchange, which would be headquartered in Dallas. They are now seeking registration with the U.S. Securities and Exchange Commission to operate as a national securities exchange later this year.

“Texas and the other states in the southeast quadrant have become economic powerhouses. Combined with the demand we are seeing from investors and corporations for expanded alternatives to trade and list equities, this is an opportune time to build a major, national stock exchange in Texas,” said James Lee, founder and CEO of TXSE Group.

Stock exchanges are private institutions where stocks, bonds and other securities are traded. If the SEC clears TXSE to begin operations, it will be the first stock exchange to launch in the country in recent years.

According to the Wall Street Journal, which first reported on the creation of the new exchange, TXSE promises to be more CEO-friendly than other exchanges and wants to capitalize on discontent over new rules and rising compliance costs at Nasdaq and NYSE.

“If we look at the three states with the largest economy, New York has two stock exchanges. Texas, comparably to California, is growing economically and demographically really fast, and already has a big number of Fortune 500 biggest companies headquarters, so it makes sense Dallas would be an ideal place,” said Steven Pedigo, a professor at the University of Texas at Austin’s LBJ School of Public Affairs and an expert in economic and urban development.

But it could be difficult for a new exchange to take off in the U.S. listings market, where the Nasdaq and NYSE have dominated for decades. The U.S. exchange business consists of about 16 equities exchanges with NYSE accounting for more than 20% of the volume in equities trading in May and Nasdaq over 15%, according to Bloomberg. Nasdaq acquired the Philadelphia Stock Exchange and Boston Stock Exchange, two of the oldest exchanges in the country, in 2007. The NYSE bought the Chicago Stock Exchange in 2018.

“What makes this project interesting is the big companies that supported and financed the new stock exchange, that is why it could be a serious competitor. But it is a ‘to be continued’ story,” Pedigo said.

TXSE founders said they chose Texas as the home for the new national securities exchange because of the state’s rapid economic and population growth. Texas has been a leader in attracting business relocations and expansions in recent years. More than 7,200 firms relocated to Texas between 2010 and 2019, creating nearly 103,000 jobs, according to data from the Federal Reserve Bank of Dallas. Businesses that relocated to Texas mostly went to the state’s major metropolitan areas, with Dallas and Houston being the favored destinations.

Major corporations like Tesla and Toyota have chosen the state as their new home base in recent years. Big financial companies like Goldman Sachs have also made big investments lately in Dallas.

Pedigo said this new stock exchange wouldn’t necessarily lead to more jobs being created in the state but would help further bolster the pro-business image Texas has been working on for years.

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.

Houston company with revolutionary neurodegenerative disease treatment shares milestones since IPO

ring that bell

After announcing its initial public offering earlier this year, a Houston therapeutics company has celebrated the milestone and announced recent growth as well.

Coya Therapeutics (Nasdaq: COYA) rang the closing bell last week. The clinical-stage biotech company, which has developed a biologics therapy that prevents further spreading of neurodegenerative diseases by making regulatory T cells functional again, announced the closing of its $15.25 million IPO in January.

"We launched our IPO into one of the toughest biotech capital markets in recent memory and are enormously grateful to all our investors for the confidence they then showed in our prospects," says Howard Berman, CEO and chairman of Coya, in a June 12 letter to stockholders. "I believe that to date, we’ve executed strongly against the goals we then established, and I remain excited about our future."

In the letter, Berman shares some of the recent clinical successes from two treatments — COYA 302, a treatment for ALS, and COYA 301, a treatment for Alzheimer’s Disease. Both treatments have seen strong clinical proof of concept data in the respective open-label studies.

Earlier this year, Coya expanded its C-suite to include Dr. Arun Swaminathan as chief business officer. He has over 20 years of hands-on health care business executive experience. Prior to Coya, Swaminathan served in the same role for Actinium Pharmaceuticals.

"Arun is actively engaged in exploring potential strategic opportunities across our portfolio of assets as we believe successful partnering efforts have the potential to enhance our scientific bona fides, leverage our technology into new areas of unmet medical need, and importantly, possibly secure upfront fees and associated non-dilutive funding," Berman writes in the letter. "We look forward to pursuing additional value creation catalysts that further highlight our entrepreneurialism and ability to execute, while maintaining focus on our core assets."

The latest addition to the Coya team is Guillaume Dorothée, who joins the company's scientific advisory board. A leading expert on the role that the immune system and peripheral-central immune crosstalk play in the pathophysiology of Alzheimer's, he's a tenured research director and team head in neuroimmunology at the French National Institute of Health and Medical Research in Paris.

“I am glad and honored to join such eminent scientists on the prestigious SAB of Coya Therapeutics," he says in a June 5 statement from Coya. "I am fully convinced that innovative Treg-based immunomodulatory approaches, as developed by Coya, are highly promising therapeutic strategies for the treatment of neurodegenerative disorders and other neuroinflammatory conditions. I will be happy to help Coya Therapeutics in this exciting endeavor.”

Recently, Berman joined the Houston Innovators Podcast to discuss Coya's mission and plan post IPO.

Rice University launches new venture fund for university-affiliated startups

startup support

Rice University has launched its new One Giant Leap Ventures Fund I, which will invest in the university’s spinouts and alumni-founded startups.

The early-stage institutional venture fund will function with a hybrid structure that allows for participation from traditional equity investors and philanthropic investors. According to the university, the fund will invest up to $500,000 per Rice-affiliated company.

To be considered eligible for funds, companies must use intellectual property licensed by the university or be led or founded by alumni.

One Giant Leap will draw on support and mentorship from Rice’s pool of 60,000 alumni and aims to create educational opportunities within the investment phases, work with graduate and undergraduate venture students, explore the scaling and commercialization of their ideas, and help investigate all the facets of venture capital.

“Rice alumni bring an extraordinary depth of experience as entrepreneurs, investors and industry leaders, and One Giant Leap creates new ways to put that expertise to work for the next generation of Rice innovators,” Stephen Bayer, vice president for development and alumni relations, said in a news release. “It strengthens the connection between our alumni and the university while giving them meaningful opportunities to mentor, advise and support Rice-affiliated companies as they grow.”

The fund held its first close in August and made its first investment into Rice brain health spinout Motif Neurotech. Led by Rice faculty member Jacob Robinson, Motif is working to commercialize a minimally invasive neurostimulator that targets treatment-resistant depression. In May, the FDA approved the company to move forward with its first clinical trial.

“Research produces breakthrough technologies and our academic environment forms outstanding entrepreneurs,” said Adrian Trömel, the fund’s managing director, a Rice alumnus and a startup founder who also serves as Rice’s interim chief innovation officer.

One Giant Leap joins the already long list of Rice-led programs that foster innovation, including the Liu Idea Labs for Innovation and Entrepreneurship’s Innovation Fellows and Summer Venture Studio, the Rice Alliance’s Business Plan Competition, the Ion District, Woodside Rice Decarbonization Accelerator, Rice Nexus, the Biotech Launchpad and RBL Ventures and its upcoming 200,000 square-foot research lab the Arc.

“With One Giant Leap, I am excited that we are creating a unique structure that brings together traditional investment and philanthropic participation to invest in and help catalyze our startups, engage the deep expertise within the Rice ecosystem and transform those strengths into real-world impact,” Trömel added in the release.

New statewide plan aims to eliminate cervical cancer in Texas by 2032

fighting cancer

MD Anderson, on behalf of a coalition of health systems, has announced a new plan to eliminate cervical cancer in Texas.

The five-year Texas Lone Star Cervical Cancer Elimination Plan was launched during the Cancer Prevention and Research Institute of Texas (CPRIT) 2026 Innovations Conference in Galveston this month.

The plan focuses on three major pillars with goals to be achieved by 2032:

  • HPV vaccination: Increase the percentage of Texas boys and girls up to date on human papillomavirus (HPV) vaccination by age 15 from 50.5 percent to 80 percent
  • Cervical cancer screening: Raise the share of Texas women up to date on cervical cancer screening from 64 percent to 80 percent
  • Timely follow-up, diagnosis and treatment: Ensure 80 percent of women receive diagnostic follow-up and treatment when needed through community outreach, patient navigation, provider training and survivorship support

Overall, the coalition wants to see fewer than four new cases of cervical cancer annually per 100,000 Texas women by 2032, according to a news release from MD Anderson. Currently, Texas has an incidence rate of 9.5 women per 100,000 diagnosed with cervical cancer, compared with 7.5 women per 100,000 nationally.

“Texas has the tools to prevent nearly every case of cervical cancer, but tools can save lives only when people can utilize them,” Dr. Ernest Hawk, vice president and division head of Cancer Prevention and Population Sciences at MD Anderson, said in the release. “The Lone Star Cervical Cancer Elimination Plan gives us a shared roadmap to vaccinate more of our children, screen more of our women and make sure every abnormal result leads to care. With innovations like HPV self-collection and the commitment of partners across the state, elimination is within reach.”

About 40 other hospitals, health care organizations and companies join MD Anderson in the coalition that launched the Lonestar Plan. Those based in Houston include Houston Methodist, Rice University, UTHealth Houston, Texas Children's Hospital, Houston Health Department and others.

The CPRIT also announced its Texans Conquer Cancer Awards and its CPRIT Champion awards during the Innovations Conference this week. Several are based in Houston, including:

  • Zhiqiang An, co-founder of CrossBridge Bio, Director of the Texas Therapeutics Institute, and Vice President of Drug Discovery at the University of Texas Health Science Center at Houston
  • Dr. Abbey Berenson, Director of the UTMB Center for Interdisciplinary Research in Women's Health Care
  • Dr. Michael Taylor, Chair of Pediatric Neuro-Oncology at Texas Children's Cancer and Hematology Center and Director of Texas Children's Pediatric Brain Tumor Research Program

To date, the CPRIT has awarded more than $4.2 billion in grants to fight cancer in the state. Over the summer, it awarded four $2 million grants to institutions in Houston and Bryan for the creation or expansion of “core” cancer research facilities.

Texas Medical Center Innovation recently announced that its $2 million grant would renew its Accelerator for Cancer Therapeutics for five years. Read more from TMCi about the renewal here.
