Clearfield Inc., the Brooklyn Park-based optical fiber company that began as a corporate spinoff in 2008, has never had an unprofitable year. It also has never had a year like 2021.
Revenue climbed 50% to $140 million in Clearfield's fiscal year ended September. Expenses didn't rise nearly as much, and its bottom line doubled to just over $20 million.
Investors saw not just performance at Clearfield but, with broadband heading to individual homes, more opportunity ahead.
Clearfield's share price more than tripled from $24 to $84.42 at the close Friday, pushing its market value above $1 billion and making it the second-best performer of Minnesota's 77 major public companies in 2021.
"We saw an explosion of demand. We executed," Cheri Beranek, the company's co-founder and chief executive, said last week. "We're going to deploy as much fiber in the next five years as the last 20 ... We are as much a value at $80 as we were at a fraction of that."
In a year when the S&P 500 delivered a total return of around 27%, the Piper Sandler Minnesota index rose 23%. That difference is shaped by some big Minnesota names that underperformed the S&P including Best Buy, which was down about 5% in 2021, and Medtronic, whose shares are down more than 10%.
The best Minnesota stock performer? Late-charging Brooklyn Park-based Insignia Systems, the provider of digital and in-store advertising displays for consumer goods companies. The company announced it was exploring strategic alternatives on Dec. 6, and speculators have since driven up the share. Its share price nearly tripled for the year with all of the growth in the last weeks.
The Russell 2000 index, a broader survey of smaller-capitalization stocks worth $2 billion or less, jumped 14% in 2021.
