HM Transport Inc.

Before HM Transport was formed, a bus company named Laguna Transport Company Inc. or LTCI, a sister company of JAM was established in the early 1980s. It services routes from Santa Cruz, Laguna, to Lawton, Manila via Taft Avenue, and Cubao, Quezon City, along with other competitors, Kapalaran Bus Lines, also a provincial bus company that is established in the same decade; however, it was phased out in the mid-1990s due to labor disputes, and Batangas Laguna Tayabas Bus Company Inc. (now Del Monte Land Transport Bus Company or DLTBCo).

In 2001, a major split out occurred. This resulted to forming of HM Transport Inc. that serves routes from Santa Cruz, Laguna, to Cubao, Quezon City, and Alabang, Muntinlupa. Another one is Green Star Express, a provincial bus company servicing routes, this time, from the same place to Lawton, Manila. Thus, the brand name Laguna Transport Company Inc. was then changed into its new name Laguna Express Inc. or LEI, but it was rebranded into Calamba Megatrans Inc. in 2007. This bus company services Calamba-Plaza Lawton, Manila route, the Santa Cruz - Cubao route, and for a time, the Alabang - Santa Cruz route.

Both HM Transport and Green Star Express dominate other provincial buses in Laguna. With its terminal at Barangay Pagsawitan, Pagsanjan, Laguna after passing through Santa Cruz, Laguna, these bus companies share each other at the old garage of defunct Kapalaran Bus Lines. After the JAC Liner Inc. buy out of Green Star Express Inc and Laguna Express Inc., the terminal was moved to the former HM Liner terminal.

In July 2019, HM Transport launched their P2P route for Balagtas, Pandi making the first bus route in the city, and Plaridel from Trinoma.

In March 2024, HM Transport launched their route between Alabang and Tutuban as part of their bus augmentation of the PNR Metro Commuter Line, following the construction of North–South Commuter Railway.

In May 2026, HM Transport announced to launched their inter-provincial route between Turbina, Calamba and Baguio City with a total of 12 trips per day.
