It is a major player in the European seafood industry and also owner of sister company, Findus AB, based in Malmö, Sweden.

The next generation of the Young family - brothers Gordon, Stanley, Douglas, and Malcolm - took over in the late 1930s and set up a new subsidiary for its wholesaling business.

Another subsidiary added dockside purchasing and processing operations in Grimsby, which later emerged as the United Kingdom's (and for a time, the world's) busiest fishing port.

By the mid-1980s, however, Imperial was caught in an era of hostile takeovers, becoming the target of a number of companies including United Biscuits Plc (UB).

Bluecrest, founded in 1975 by Frank Flear, was a British manufacturer and processor of fish products based in Grimsby, England, UK.

In 1999 Booker sold Bluecrest to a management buyout of rival Young's Seafood, backed by Legal & General Ventures (LGV).

The newly capitalised company made its first acquisition (of the chilled seafood division of Albert Fisher, based in Newcastle), in June 2003.

The Young's Foodservice subsidiary focuses on the restaurant and catering industry whilst Polarfrost Seafoods specializes in fish frozen at sea.

Young's was the official sponsor of Grimsby Town F.C., taking over the kit sponsorship from the final home match of the 2003–2004 football season.

At the end of the 2021–22 season it was announced that Grimsby would not be renewing the sponsorship deal after an 18-year spell as the club's primary kit sponsor.
