Heidmar Maritime Holdings Corp. (HMR)

Heidmar Maritime Holdings Corp. is a commercial and technical management company serving the tanker shipping industry. Rather than relying mainly on owning ships, Heidmar manages vessels on behalf of third-party shipowners, including through commercial pools in which multiple owners' tankers are operated together to improve employment and earnings.

Its services cover chartering, voyage operations, and commercial management for crude oil and refined products tankers, as well as related technical and maritime services. The company earns fees tied to the vessels it manages and the cargoes they carry, and it works with oil majors, traders and other charterers.

Heidmar is based in Athens, Greece, and became a Nasdaq-listed company in 2025 through a business combination with MGO Global.
