King Slide Works, a maker of server rails—metal frames on which equipment is mounted in server cabinets—has been riding the boom in demand for AI data centers. Shares of the Kaohsiung-based company jumped more than 50% from a year ago, landing founder and chairman Lin Tsung-Chi on the list for the first time with a fortune of $2.9 billion.

Lin set up King Slide in 1986 as a manufacturer of rails and other fittings for furniture, and expanded into server rails in 2001 when the company secured U.S. computer maker Compaq as a client. It proceeded to win over other computer giants, such as IBM and Dell, to eventually become one of the largest suppliers of server rails in the world.

Thanks partly to rocketing U.S. sales, which more than doubled year-on-year in 2024 to account for nearly half of the total, King Slide logged a 76% rise in revenue to NT$10.1 billion ($333 million) while net profit jumped 128% to NT$6.2 billion. Despite the looming tariff war, the company is pressing ahead with a $26 million investment in a new plant in Texas that is slated to open next year.
