WMS Industries Inc. was formed in 1974 and achieved great success in the pinball, video arcade and home video game markets. With a demonstrated track record as a company that could "make great games", video and software technology, and manufacturing facilities all in place, WMS' foray into gaming was a natural progression for the corporation.

WMS Gaming Inc. started out in the video lottery terminal (VLT) business in 1991. The company created, manufactured and placed VLTs in jurisdictions throughout North America. Once successfully established in the video lottery market, WMS Gaming moved into the casino gaming business with the introduction of a video poker game. A year later, the Company unveiled a complete line of technically advanced upright slot machines.

In 1997, the company premiered what would be, and still is, its most successful video slot machine to date, Reel 'em In®. This multi-coin, multi-line game offered tons of bells and whistles for the slot player. In an effort to produce an enhanced playing experience, WMS Gaming installed full color high-resolution screens in its games, created full color, detailed graphics, provided an entertaining game theme with many betting options, and increased the hit frequency. These features translated to tremendous player acceptance, increased play and therefore, increased earnings.

Since 1998, WMS Industries has been engaged entirely in the manufacture, sale, leasing and licensing of gaming machines.

WMS Industries Inc. is traded on the New York Stock Exchange (symbol: WMS). The Company's subsidiary is WMS Gaming Inc.
