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
  • TotalEnergies, No. 23, $218.9 billion, U.S. headquarters in Houston
  • BP, No. 25, $213 billion, U.S. headquarters in Houston
  • Chevron, No. 29, $200.9 billion, global headquarters relocating to Houston in 2024
  • Phillips 66, No. 52, $149.9 billion, global headquarters in Houston
  • Engie, No. 130, $89.3 billion, North American headquarters in Houston
  • Sysco, No. 163, $76.3 billion, global headquarters in Houston
  • ConocoPhillips, No. 235, $58.6 billion, global headquarters in Houston
  • Enterprise Products Partners, No. 303, $49.7 billion, global headquarters in Houston
  • Plains GP Holdings, No. 311, $48.7 billion, global headquarters in Houston
  • LyondellBasell, No. 368, $41.1 billion, global headquarters in Houston

8 Houston energy companies land on Time's top greentech list for 2025

top honor

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.

What a difference a year makes. I have been coming to CERAWeek for as long as I can remember and the Agora track within CERAWeek since it originated. Although freshness likely distorts my thinking, I cannot remember a CERAWeek that seemed so different from the previous year's than this one.

This certainly isn’t a comprehensive summary of the conference, but some of my key take forwards from last week's events. Continue reading Barbara J. Burger's takeaways.

From raging wildfires to dangerous dust storms and fierce tornadoes, Texans are facing extreme weather conditions at every turn across the state. Recently, thousands in the Texas Panhandle-South Plains lost power as strong winds ranging from 35 to 45 mph with gusts upwards of 65 mph blew through. Meanwhile, many North Texas communities are still reeling from tornadoes, thunderstorms, and damaging winds that occurred earlier this month.

With the extreme weather conditions increasing in Texas and nationally, recovering from these disasters will only become harder and costlier. When it comes to examining the grid’s capacity to withstand these volatile changes, we’re past due. As of now, the grid likely isn’t resilient enough to make do, but there is hope.
