Yost's species were a yellow-skinned humanoid race from the Delta Quadrant.

In 2375, the USS Voyager encountered Supervisor Yost's ship after Lieutenants Tuvok and Paris and The Doctor crash landed on a planet within a subspace sinkhole. Yost informed Captain Kathryn Janeway that they had lost eleven ships to the anomaly, and that they had decided to close the rift in less than a day rather than lose any more ships to it. Janeway pleaded with him to postpone his mission, but Yost was adamant that he was going to continue. Janeway refused to give up on her stranded crew and eventually managed to transport them out of the sinkhole before Yost closed it. (VOY: "Gravity")

In 2376, several members of Yost's species could be seen in the audience during a game of tsunkatse. (VOY: "Tsunkatse")
