Mobile Mini offers a wide range of storage options, including big, metal units you may have seen at construction sites. The company does business in the United States, Canada and the United Kingdom.

President and CEO Erik Olsson said they’ll keep growing.

“We’ve added 17 or 18 territories since the beginning of the year. I’m not going to come out with a specific number here, but obviously we look to continue to do this,”  Olsson said.

Mark Funk, executive vice president and CFO, said this marks the 21st consecutive quarter of year-to-year growth in rental revenues.

"Our increase in portable storage rental revenues were driven by both a solid increase in units on rent as well as a 2.3 percent increase in our rental rates," he said.

Olsson said the company plans to continue raising rental rates. In June, Mobile Mini shareholders are scheduled to get a cash dividend of nearly 21 cents per share.
