More than 60 Texas-based companies appear on Forbes’ 2025 list of the world’s 2,000 biggest publicly traded companies, and nearly half come from Houston, the majority in the energy sector.

Among Texas companies whose stock is publicly traded, Spring-based ExxonMobil is the highest ranked at No. 13 globally.

Rounding out Texas’ top five are Houston-based Chevron (No. 30), Dallas-based AT&T (No. 35), Austin-based Oracle (No. 66), and Austin-based Tesla (No. 69).

Ranking first in the world is New York City-based J.P. Morgan Chase.

Forbes compiled this year’s Global 2000 list using data from FactSet Research to analyze the biggest public companies based on four metrics: sales, profit, assets, and market value.

“The annual Forbes Global 2000 list features the companies shaping today’s global markets and moving them worldwide,” said Hank Tucker, a staff writer at Forbes. “This year’s list showcases how despite a complex geopolitical landscape, globalization has continued to fuel decades of economic growth, with the world’s largest companies more than tripling in size across multiple measures in the past 20 years.”

The U.S. topped the list with 612 companies, followed by China with 317 and Japan with 180.

Here are the rest of the Texas-based companies in the Forbes 2000, grouped by the location of their headquarters and followed by their global ranking.

Houston-based Phillips 66 faces federal charges related to alleged Clean Water Act violations

investigation station

Oil company Phillips 66 has been federally indicted in connection with alleged violations of the Clean Water Act in California, authorities said Thursday.

The Houston-based company is accused of discharging hundreds of thousands of gallons of industrial wastewater containing excessive amounts of oil and grease, the U.S. Department of Justice said.

The company allegedly dumped the wastewater from its Carson oil refinery into the Los Angeles County sewer system in 2020 and 2021 and did not report the violations, prosecutors said.

Phillips is charged with two counts of negligently violating the Clean Water Act and four counts of knowingly violating the Clean Water Act. The company faces up to five years of probation on each count and a maximum of $2.4 million in fines.

An arraignment date has not been set.

“Phillips 66 will continue its cooperation with the U.S. Attorney’s office and is prepared to present its case in these matters in court,” a spokesperson said in a statement Thursday. “The company remains committed to operating safely and protecting the health and safety of our employees and the communities where we operate.”

Last month, Phillips announced it would close its Southern California refinery by the end of 2025, citing market concerns. That refinery accounts for about 8% of California’s refining capacity, according to the state’s Energy Commission.

The company also operates a refinery near San Francisco that accounts for about 5% of California’s refining capacity, according to the state Energy Commission.

Houston energy companies score big on annual Fortune 500 ranking

big cos.

Fourteen businesses with global or regional headquarters in the Houston area appear on Fortune’s new list of the world’s 500 biggest companies.

Oil and gas company Saudi Aramco, whose headquarters for the Americas is in Houston, leads the Houston-area pack. With annual revenue of $494.9 billion, it lands at No. 4 on the Fortune Global 500. Ahead of Saudi Aramco are U.S. retailers Walmart and Amazon, and Chinese electric company State Grid.

To put Saudi Aramco’s annual revenue in perspective, the total is slightly above the gross domestic product for the Philippines.

For the third year in a row, Saudi Aramco stands out as the most profitable member of the Fortune Global 500. The company racked up $121 billion in profit last year.

Overall, Saudi Aramco and 32 other petroleum refiners — many of them with a significant presence in the Houston area — made the Fortune Global 500.

“The Global 500 is the ultimate scorecard for business success. The aggregate revenue of the Fortune Global 500 in 2023 reached $41 trillion, a record level. That sum represents more than a third of global GDP — a sign of how much economic power is concentrated in these companies,” Scott DeCarlo, Fortune’s vice president of research, says in a news release.

Here’s the rundown of Fortune Global 500 companies with global or regional headquarters in the Houston area, including the ranking and annual revenue for each:

  • Saudi Aramco, No. 4, $494.9 billion, Americas headquarters in Houston
  • ExxonMobil, No. 12, $344.6 billion, global headquarters in Spring
  • Shell, No. 13, $323.2 billion; U.S. headquarters in Houston

Following years of speculation, Chevron announces HQ move to Houston

big news

The Energy Capital of the World is adding another jewel to its corporate crown.

With the impending move of Chevron’s headquarters from Northern California to Houston, the Houston area will be home to 24 Fortune 500 companies. Chevron ranks 15th on this year’s Fortune 500.

Oil and gas giant Chevron, currently based in San Ramon, California, will join three Fortune 500 competitors that already maintain headquarters in the Houston area:

  • Spring-based ExxonMobil, No. 7 on the Fortune 500
  • Houston-based Phillips 66, No. 26 on the Fortune 500
  • Houston-based ConocoPhillips, No. 68 on the Fortune 500

Chevron, which posted revenue of $200.9 billion in 2023, employs about 7,000 people in the Houston area and about 2,000 people in San Ramon. The company says its chairman and CEO, Mike Wirth, and vice chairman, Mark Nelson, will move to Houston before the end of 2024.

In an interview with The Wall Street Journal, Wirth acknowledged Chevron’s differences of opinion with California policymakers regarding energy matters.

“We believe California has a number of policies that raise costs, that hurt consumers, that discourage investment and ultimately we think that’s not good for the economy in California and for consumers,” Wirth said.

Chevron expects all of its corporate functions to shift to Houston over the next five years. Jobs that support the company’s California operations will remain in San Ramon, where Chevron employs about 2,000 people. Some Chevron employees in San Ramon will relocate to Houston.

The company’s move to Houston hardly comes as a surprise. Speculation about a relocation to Houston intensified after Chevron sold its 98-acre San Ramon headquarters in 2022 and moved corporate employees to leased office space. Over the past several years, Chevron has shifted various corporate functions to Houston.

“This is just the final step that many industry observers were waiting to happen,” Ken Medlock, senior director of the Baker Institute’s Center for Energy Studies at Rice University, says in a news release.

“To start, Houston provides a world-class location for internationally focused energy companies, which is why there is such a massive international presence here,” Medlock adds. “Texas is also the nation’s largest energy producer across multiple energy sources and is poised to lead in emerging opportunities such as hydrogen and carbon capture, so Houston is a great place for domestically focused activities as well.”

The announcement of Chevron’s exit from California comes just a year after ExxonMobil finalized its relocation from Irving to Spring.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, says in a post on the organization’s website.

“With deep roots in our region,” he adds, “Chevron is [a] key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

Phillips 66 reports full capacity milestone of renewable energy facility

up and running

Houston-based Phillips 66 announced the full conversion of a California renewable energy facility.

The Rodeo Renewable Energy Complex will expand commercial-scale production to “position the company as a leader in renewable fuels,” according to a news release.

The facility, located 200 miles south of San Francisco, California, increased rates to approximately 50,000 barrels per day (or 800 million gallons per year), which reached the company’s goal of achieving full capacity by the second quarter of 2024. This also aligns with its commitment to energy transition and provide customers with lower-carbon solutions.

The Rodeo complex has new pre-treatment units that process lower carbon intensity feedstocks like cooking oil, fats, greases and vegetable oil. It began producing approximately 30,000 barrels per day of renewable fuel at the end of the first quarter of 2024. Rodeo Renewed is designed to produce renewable diesel and sustainable aviation fuel, and was started in 2020, and mostly serves the West Coast and California areas.

“Phillips 66 has reached another important milestone, which is a testament to our employees’ dedication to achieving our company’s strategic priorities,” executive vice president of Refining Rich Harbison said in a news release. “The facility running at full capacity supports the growing demand for renewable fuels, lowers our carbon footprint and creates long-term value for our shareholders.”

Energy sector AI spending is set to soar to $13B, report says

eyes on ai

Get ready for a massive increase in the amount of AI spending by oil and gas companies in the Houston area and around the country.

A new report from professional services firm Deloitte predicts AI will represent 57 percent of IT spending by U.S. oil and gas companies in 2029. That’s up from the estimated share of 23 percent in 2025.

According to the analysis, the amount of AI spending in the oil and gas industry will jump from an estimated $4 billion in 2025 to an estimated $13.4 billion in 2029—an increase of 235 percent.

Almost half of AI spending by U.S. oil and gas companies targets process optimization, according to Deloitte’s analysis of data from market research companies IDC and Gartner. “AI-driven analytics adjust drilling parameters and production rates in real time, improving yield and decision-making,” says the Deloitte report.

Other uses for AI in the oil and gas industry cited by Deloitte include:

  • Integrating infrastructure used by shale producers
  • Monitoring pipelines, drilling platforms, refineries, and other assets
  • Upskilling workers through AI-powered platforms
  • Connecting workers on offshore rigs via high-speed, real-time internet access supplied by satellites
  • Detecting and reporting leaks

The report says a new generation of technology, including AI and real-time analytics, is transforming office and on-site operations at oil and gas companies. The Trump administration’s “focus on AI innovation through supportive policies and investments could further accelerate large-scale adoption and digital transformation,” the report adds.

Chevron and ExxonMobil, the two biggest oil and gas companies based in the Houston area, continue to dive deeper into AI.

Chevron is taking advantage of AI to squeeze more insights from enormous datasets, VentureBeat reported.

“AI is a perfect match for the established, large-scale enterprise with huge datasets—that is exactly the tool we need,” Bill Braun, the company’s now-retired chief information officer, said at a VentureBeat event in May.

Meanwhile, AI enables ExxonMobil to conduct autonomous drilling in the waters off the coast of Guyana. ExxonMobil says its proprietary system improves drilling safety, boosts efficiency, and eliminates repetitive tasks performed by rig workers.

ExxonMobil is also relying on AI to help cut $15 billion in operating costs by 2027.

“There is a concerted effort to make sure that we’re really working hard to apply that new technology … to drive effectiveness and efficiency,” Darren Woods, executive chairman and CEO of ExxonMobil, said during a 2024 earnings call.

SLB partners with renewables company to develop next-gen geothermal systems

geothermal partnership

Houston-based energy technology company SLB and renewable energy company Ormat Technologies have teamed up to fast-track the development and commercialization of advanced geothermal technology.

Their initiative focuses on enhanced geothermal systems (EGS). These systems represent “the next generation of geothermal technology, meant to unlock geothermal energy in regions beyond where conventional geothermal resources exist,” the companies said in a news release.

After co-developing EGS technology, the companies will test it at an existing Ormat facility. Following the pilot project, SLB and Nevada-based Ormat will pursue large-scale EGS commercialization for utilities, data center operators and other customers. Ormat owns, operates, designs, makes and sells geothermal and recovered energy generation (REG) power plants.

“There is an urgent need to meet the growing demand for energy driven by AI and other factors. This requires accelerating the path to clean and reliable energy,” Gavin Rennick, president of new energy at SLB, said in a news release.

Traditional geothermal systems rely on natural hot water or steam reservoirs underground, limiting the use of geothermal technology. EGS projects are designed to create thermal reservoirs in naturally hot rock through which water can circulate, transferring the energy back to the surface for power generation and enabling broader availability of geothermal energy.

The U.S. Department of Energy estimates next-generation geothermal, such as EGS, could provide 90 gigawatts of electricity by 2050.
