Black Hills Corp. (BKH) (the “Company”) today announced the pricing of a registered public offering of 5.5 million shares of its common stock at $40.25 per share, for total gross proceeds of approximately $221.4 million. In addition, the Company announced the pricing of its registered public offering of 5.2 million equity units, for total gross proceeds of $260.0 million. The offerings (which are not conditioned on one another) are expected to close on or about Nov. 23, 2015, subject to customary closing conditions.

The Company has granted the underwriters a 30-day option to purchase up to an additional 825,000 shares of its common stock, and a 13-day option to purchase up to 780,000 additional equity units, upon the same terms as their respective offerings.

Each equity unit will be issued in a stated amount of $50 and will initially consist of a contract to purchase Company common stock and a 1/20, or 5%, undivided beneficial ownership interest in $1,000 principal amount of remarketable junior subordinated notes due 2028. Pursuant to the purchase contracts, holders are required to purchase Company common stock no later than Nov. 1, 2018.

Total annual distribution on the equity units will be at the rate of 7.75%, consisting of quarterly interest payments on the remarketable junior subordinated notes at a rate of 3.50% per year and quarterly contract adjustment payments on the purchase contracts at a rate of 4.25% per year. The reference price for the equity units is $40.25 per share. The minimum settlement rate under the purchase contracts is 1.0572 shares of Company common stock, which is approximately equal to the $50 stated amount per equity unit, divided by the threshold appreciation price of $47.2938 per share, which represents a premium of approximately 17.5% over the reference price. The maximum settlement rate under the purchase contracts is 1.2422 shares of Company common stock, which is approximately equal to the $50 stated amount per equity unit, divided by the reference price. Each of the settlement rates is subject to adjustment in certain circumstances.

The Company intends to use the proceeds from these offerings, which are expected to be approximately $465.8 million in the aggregate or approximately $535.7 million in the aggregate if the options to purchase additional shares and equity units are exercised in full (after deducting underwriting discounts and commissions but before deducting estimated offering expenses), to partially fund the pending acquisition of SourceGas Holdings LLC. The acquisition is expected to close in the first half of 2016.
