Exact spokesman J.P. Fielder said Sampleminded has more than 20 employees who are now Exact Sciences employees, and are based in Salt Lake City. “We will continue to grow and expand that team,” Fielder said.

Fielder would not say if this is Exact’s first acquisition, saying, “We don’t typically comment on acquisitions that we’ve made.”

Conroy said Exact plans to buy land “near our headquarters in Madison” during the fourth quarter. The company currently leases office space at the former Spectrum Brands headquarters, 601 Rayovac Drive. Exact is expected to announce soon that it will build a second laboratory at the site.

Exact is expanding its current processing lab in the town of Madison to raise capacity from the current 1 million samples a year to 2.5 million samples a year. Conroy told analysts the new lab will be able to process 2 million test results a year to start, “with the ability to expand that location further on a long-term basis,” he said.

Exact has more than 1,000 employees, with more than 750 of them in the Madison area.

Exact Sciences stock hit a new high of $57.95 before closing at $54.99, up $4.89, or 9.8 percent, from Monday’s close.

Trading was heavy, with 6.4 million shares traded, up from the average daily volume of 1.4 million shares.
