Houston Public Companies

The following is a list of public companies in the Houston area. I have included companies who have their operational headquarters in Houston, even if they have their official registered office overseas.

The list of public companies is very fluid and there may be errors or omissions. I will do my best to keep this list updated.

Market capitalization as of May 31, 2024.
