Top Manufacturing Companies in Houston
HPE moved its global headquarters to the Houston area in 2022 and uses the campus as a hub for high-performance computing and enterprise infrastructure. Known for building some of the world’s fastest supercomputers, the company has pivoted its entire business model toward building turnkey systems that support the "AI grid,” connecting distributed AI factories across regional and edge sites.
Oceaneering makes underwater robotics and specialized subsea hardware used in deep-sea operations across the offshore energy, defense and aerospace industries. Founded in 1964, its Houston-based applied technology teams also develop animatronics and trackless ride systems for theme parks, including Universal Studios and Disney parks, as well as autonomous mobile robots for warehouse operations and logistics.
Tesla is building a $200 million Megafactory near Houston to produce its Megapack energy storage systems at scale. The site is expected to create about 1,500 jobs by 2028 as the company grows its footprint in grid-level battery storage, leaning into a broader role beyond electric car manufacturing as a physical AI and energy player.
NASA’s Johnson Space Center oversees astronaut training, spacecraft design and mission control, including the upcoming Artemis II lunar flyby. But beyond research and flight operations, the facility functions as a massive manufacturing hub, where full-scale spacecraft and robotic systems are prototyped, tested and assembled. Its new Exploration Park, a 240-acre space systems campus that’s under construction, is designed for private aerospace partners to build human-rated hardware, life-support systems and clean-room operations directly on site.
Honeywell is a global technology and manufacturing company that builds the systems that run factories, refineries, chemical plants and energy operations. Its Houston hub is responsible for designing and producing hardware like smart sensors, gas detectors and temperature control systems, as well as software platforms, including its flagship Experion PKS platform, which is a live central control system. It helps everything from chemical reactors to oil rigs prevent accidents, save energy, cut carbon emissions and keep processes up and running.
Based near the Houston Spaceport, Intuitive Machines is a space infrastructure company that hit a $943 million backlog after its high-profile lunar landings in 2024 and 2025. After becoming the first private company to land on the moon, Intuitive Machines is now expanding into a full-service lunar mission contractor, and aims to roll out a continuous 4G/LTE and satellite web accessible from outer space.
Energy conglomerate ExxonMobil runs its global headquarters from a 385-acre campus in Spring, Texas — a suburb just north of Houston — built to host 10,000 employees. As the largest publicly traded oil and gas company in the world, the company turns crude oil into fuels such as gasoline, diesel and jet fuel, along with petrochemicals used to make plastics, synthetic rubber and industrial materials.
Global pharmaceutical giant Eli Lilly and Company is building a $6.5 billion state-of-the-art manufacturing site at Generation Park in Houston to produce active pharmaceutical ingredients for its newest synthetic medicines. This facility — one of the largest pharma-related investments in the state’s history — will serve as a primary production hub for orforglipron, an oral GLP-1 pill to treat obesity, as well as critical treatments for oncology, immunology and neuroscience.
SLB, formerly Schlumberger, is shifting from traditional oilfield services toward a more software-driven energy model. Founded in 1929, the company supplies the petroleum industry with specialized services — including seismic data processing, directional drilling and well completions — while rapidly pivoting toward carbon capture and groundwater extraction. Its Houston operations combine complex subsea manufacturing with digital platforms for remote drilling and data analysis.
Under Daikin, Goodman operates one of the largest HVAC manufacturing sites in North America at its Texas Technology Park. Recently, the company has been pivoting away from traditional heating and cooling into a mission-critical infrastructure provider — installing smart home systems and high-density cooling for data centers — in response to the global AI boom.
