Latham Group, Inc.
One of the largest makers of in-ground residential swimming pools in North America, Australia, and New Zealand, Latham builds fiberglass and vinyl-liner pools, wall panels, steps, liners, and automatic safety covers used by pool builders and homeowners. It began in 1956 as a small aluminum siding business in Latham, New York, founded by Herb Latham, before pivoting to pools in the mid-1970s and growing through acquisitions. Its stock trades under the ticker symbol SWIM — a fitting nod to its backyard roots.
