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

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (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.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.

8 Houston energy giants top global corporate startup index for 2025

Global Group

Eight major players in Houston’s energy industry rank among the world’s top 20 energy companies for corporate startup activity.

The inaugural Corporate Startup Activity Index 2025, published by StartupBlink, ranks global corporations by industry. The eight Houston-area employers fall into the index’s energy and environment category.

Researchers from StartupBlink, an innovation research platform, scored more than 370 companies based on three factors: corporate involvement in startup activity, startup success and ecosystem integration.

The eight Houston-area energy employers that landed in the energy and environment category’s top 20 are:

  • No. 3 BP. Score: 13.547. U.S. headquarters in Houston.
  • No. 5 Saudi Aramco. Score: 7.405. Americas headquarters in Houston.
  • No. 7 Eni. Score: 6.255. Headquarters of Eni U.S. Operating Co. in Houston.
  • No. 8 Shell. Score: 6.217. U.S. headquarters in Houston.
  • No. 11 Occidental Petroleum. Score: 5.347. Global headquarters in Houston.
  • No. 15 Engie. Score: 3.352. North American headquarters in Houston.
  • No. 17 Repsol. Score: 2.980. U.S. headquarters for oil and gas operations in The Woodlands.
  • No. 19 Chevron. Score: 2.017. Global headquarters in Houston.

“Building a startup is hard, and navigating corporate innovation can be just as complex. This ranking is a step toward making the connection between startups and corporations more transparent, enabling startups and corporations to collaborate more effectively for mutual success,” said Eli David Rokah, CEO of StartupBlink.

Salesforce topped the global index with a score of 380.090, followed by Intel, Google, Qualcomm, and Comcast.

Telsa eyes Houston area for $10 billion solar manufacturing plant

under review

Electric vehicle and clean energy company Tesla is considering building a new $10.1 billion solar cell manufacturing facility in Fort Bend County, according to documents filed with the Texas Comptroller’s Office.

If approved, the plant, called Project Sun City, would be located on a 3,050-acre site off FM 762 and FM 1994 in Richmond, Texas. Tesla aims to finish construction in 2028, with the plant being operational by early 2029.

The plant will manufacture photovoltaic (PV) solar cells and modules that can convert sunlight into electricity. PV Magazine reports that the facility is "the largest single manufacturing investment Tesla has proposed on paper."

Advisory and consulting firm Kroll submitted the documents to the Texas Comptroller of Public Accounts and noted if an agreement regarding tax incentives isn't reached, the project will exit Texas.

Tesla has requested credits under the Jobs, Energy, Technology, and Innovation (JETI) Act. The incentive program aims to attract large, capital-intensive economic development projects by lowering the property taxes an entity must pay over 10 years if it meets requirements related to job creation and investment. For example, pharmaceutical giant Bristol Myers Squibb Co. recently announced that its forthcoming $2.3 billion Houston-area manufacturing site is a qualified project under the JETI program.

Kroll predicts that the facility would create 9,712 new full-time jobs, over 1,100 construction jobs and billions of dollars in future property tax revenue, the documents show. Additionally, it says the project will spur $1.1 billion in local business expenditures and that Texas would increase its GDP by approximately $107 billion as a result of the project activities.

Tesla opened its $200 million Megafactory in Brookshire, Texas, last year. The company is continuing its goal to deploy 100 gigawatts of solar manufacturing in the U.S before the end of 2028. According to the U.S. Energy Information Administration, 100 gigawatts is equal to about 8 percent of the country's power grid capacity.

Houston researchers land $10M grant to study how climate change drives disease threats

climate health research

Researchers from Rice University, Baylor College of Medicine and the University of Texas School of Public Health have received a $10 million grant to support research and public education on how climate change is linked to public health.

The funding comes from North Carolina-based Burroughs Wellcome Fund and is known as the organization’s Climate + Health Excellence (CHEX) award. It will be used over the next five years to launch the new FORECAST initiative, led by Rice professors and co-investigators Sylvia Dee and Joseph Campan.

FORECAST will “study how a rapidly changing environment and weather drive the emergence and expansion of deadly pathogens in human populations,” according to a release from Rice.

“This grant supports novel research linking climate change projections to health care solutions while simultaneously ensuring the next generation of scientists, leaders and policymakers have the training to assess and respond to the climate change risks that we already know are increasing every year,” Dee said in the release.

The funding will go toward a variety of new initiatives and centers.

At Rice, the funding will help launch the new Center for Climate and Environmental Health, as well as cross-campus multidisciplinary collaborations, seed grants, postdoctoral and graduate positions, and more, according to the university.

The grant will also support the statewide “Middle to Medical” climate-health educational program for youth. The program will focus on teaching how pathogens spread and how climate change plays a role in the process.

“FORECAST will prepare youth across Texas to make informed health decisions that protect themselves and their families and communities from extreme weather and disease-related risks,” Nancy Moreno, a professor of education, innovation and technology at Baylor College of Medicine and co-investigator on this grant, added in the release.

Anthony Maresso, professor of molecular virology and microbiology at Baylor College of Medicine, will share expertise in viral pathogen sewage detection that was developed during the COVID-19 pandemic; while Eric Boerwinkle, dean of the UT School of Public Health, will share insights from the Texas Wastewater Environmental Biomonitoring Network, which tracks disease-causing viruses and bacteria by testing wastewater weekly at Texas sites.

“Hotter days, bigger storms, new disease threats — Texas’s future demands preparation,” Boerwinkle added in the release. “With support from the Burroughs Wellcome Fund, the FORECAST team is helping Texas detect threats earlier and respond faster, saving lives and strengthening our economy.”

EV surge could shutter 40 refineries by 2040, Wood Mackenzie report warns

ev outlook

The rise of electric vehicles could spell trouble for Houston’s oil and gas sector, a new report suggests. But the oil and gas industry stands to benefit from potential sluggishness in U.S. adoption of EVs.

If worldwide EV adoption rises as expected, global oil demand could fall by five million barrels per day by 2040, accelerating the closure of about 40 oil refineries, says the report, published by energy research and consulting firm Wood Mackenzie. The firm’s North American hub is in Houston.

Those closures might spell trouble for refinery operators with a sizable Houston-area presence, including BP, ExxonMobil, Marathon, Saudi Aramco, and Valero. In 2025, the five companies collectively earned roughly $33 billion from downstream operations, including refineries. One caveat: Each company assigns a different definition to “downstream.”

Refineries in Organization for Economic Co-operation and Development (OECD) countries, including the U.S. but excluding Middle Eastern heavyweights, “are most at risk due to their high energy costs and carbon prices,” the Wood Mackenzie report says.

On the flip side, an abundant U.S. oil supply means American drivers have less of an incentive to switch from traditional cars to electric vehicles, despite stubbornly high fuel prices, according to the report.

Wood Mackenzie predicts EVs will account for 20 percent of the U.S. personal and commercial vehicle fleet in 2040, up from three percent in 2025. That compares with a global forecast of 25 percent in 2040, up from 4 percent last year.

Another U.S. roadblock to EV adoption cited in the report: the country’s relative lack of advanced battery manufacturing.

“Without advanced battery technologies, the U.S. auto sector is at risk of ceding its home market to non-Chinese EVs and falling behind competitors internationally,” the report says.

Furthermore, according to the report, Chinese investment in EV manufacturing in the U.S. probably will remain a no-go and tariffs on Chinese EV imports likely won’t be lifted, even if Democrats resurrected EV incentives following a White House win in 2028.

“Competition among EV manufacturers in international markets will only intensify,” the report notes. “Companies that can offer competitive products in high-growth markets will be best positioned for long-term success.”
