The IPO, the first by a US wind developer, was priced at $22 per share, above its $19-21 range anticipated by Pattern earlier this month.

Underwriters have been granted a 30-day option from the offering’s closing date to purchase up to an additional 2.4 million shares at the same price.

Pattern, based in San Francisco, will use the proceeds to pay down debt, expand its business and working capital.
