Indicating that it is discussing possible acquisitions of outdoor companies in the $25-50 million range, Black Diamond Equipment Inc. said it intends to issue 7.75 million new shares, priced at $7.50, to obtain gross proceeds of about $58.1 million. It is also granting an option to purchase an additional 1,162,500 shares for $8.7 million to the underwriters of the offering, Piper Jaffray and William Smith & Co. Due to close on Feb. 22, the new stock offering is aimed at collecting cash to pay down debt, for capital investments and for potential acquisitions. Black Diamond estimated a few days ago that its revenues probably rose by 16 percent last year to $145 million, and that they would further grow to between $160 and $165 million in 2012.
