The original version of this story included some factual inaccuracies due to misinformation from a source. The story below has been corrected.

In a 130,000 square-foot facility outside of Bryan-College Station, iBio is growing the makings of new types of therapeutics for fibrosis, cancer, and even COVID-19.

The company, which moved its headquarters from New York to Texas in July, uses novel biopharma methods to produce the vital molecules and antigens used for vaccines and other types of medical treatments through plants in a fast, sustainable way.

Other methods of creating biopharmaceutical require scientists to engineer cells to create a desired protein, which can be one of the most time consuming parts of the process, IBio's CEO Tom Isett explains. However, through iBio's FastPharming method, the team let's the plants do most of the work.

IBio introduces an Agrobacterium carrying a desired gene to manipulate the plant's DNA.

"[The bacteria] takes over the machinery of the plant leaves and it then produces the protein of interest or the biopharmaceutical that we were going to want to make for people," Isett says.

IBio then harvests the leaves and purifies the proteins to make the biopharmaceutical of interest. The entire process can save anywhere from six to 18 months in development, he estimates.

Too, if there's demand for more of the product, through this process, all scientists need to do is grow more plants.

"We have a linear scale up, it's very straightforward," says Peter Kipp, iBio's VP of translational science and alliance management. "And using some of the other competing methodologies, as you go to a bigger scale, you have new technical problems that you have to solve, but we don't."

The team discovered that an Australian species of the tobacco plant could be one of their biggest conduits in their process.

"It just grows like a weed. And that's why we like it," Kipp says.

The plant expends most of its energy in creating its leaves, where IBio extracts most of its proteins from. The plants are grown in the company's indoor, vertical hydroponic facility and are able to be harvested about every six weeks, and (it's important to note) does not contain nicotine.

IBio used their FastPharming process to introduce two vaccine candidates and a therapeutic in about six week's time. However, Isett says they're not just a COVID-19 vaccine company.

"We're mostly focused in other areas. But when [COVID] showed up, we did want to go in and see if we could address it using the speed of our system," he says.

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

27 Houston companies make Fortune 500 for 2026, led by energy giants

Houston HQs

Editor's note: This article has been updated to correct the number of companies based in the Dallas-Fort Worth area.

Houston is a giant among U.S. hubs for corporate headquarters.

The 2026 Fortune 500 lists 27 companies based in the Houston area, with many energy companies claiming top spots. Houston ties with Chicago for the second-most Fortune 500 headquarters, preceded only by New York City (53). Dallas-Fort Worth is home to 24 Fortune 500 headquarters.

Texas leads the nation for Fortune 500 headquarters (57), with California in the No. 2 spot and New York at No. 3.

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

The 2026 Fortune 500 ranks the largest U.S. corporations based on revenue in fiscal year 2025.

Here’s a rundown of the 27 Fortune 500 companies based in the Houston area.

  • No. 9 ExxonMobil
  • No. 21 Chevron
  • No. 29 Phillips 66
  • No.55 Sysco
  • No. 75 ConocoPhillips
  • No. 89 Enterprise Products Partners
  • No. 103 Plains GP Holdings
  • No. 133 Hewlett Packard Enterprise
  • No. 149 NRG Energy
  • No. 157 Quanta Services
  • No. 164 Baker Hughes
  • No. 173 Occidental Petroleum
  • No. 179 Waste Management
  • No. 201 EOG Resources
  • No. 204 Group 1 Automotive
  • No. 207 Halliburton
  • No. 223 Cheniere Energy
  • No. 236 Corebridge Financial
  • No. 262 Targa Resources
  • No. 266 Kinder Morgan
  • No. 388 Westlake
  • No. 435 CenterPoint Energy
  • No. 438 APA
  • No. 440 Comfort Systems USA
  • No. 455 NOV
  • No. 488 KBR
  • No. 496 Coterra Energy. Oklahoma City, Oklahoma-based Devon Energy and Houston-based Coterra Energy merged in early May, with the combined company retaining the Devon Energy name and the Houston headquarters.

The Greater Houston Partnership notes the Houston area soon will welcome its 28th Fortune 500 company. Expand Energy (formerly Chesapeake Energy), appearing at No. 362 on the 2026 list, says it’s moving its headquarters from Oklahoma City to Spring this year.

As the natural gas producer prepares to relocate to Texas, it’s hunting for a new leader. Nick Dell’Osso stepped down as president and CEO earlier this year. Board Chairman Michael Wichterich is interim president and CEO.

Dell’Osso became president and CEO of Oklahoma City-based Gulfport Energy effective May 28.
