Halper Sadeh LLC, an investor rights law firm, is investigating whether the sale of NorthWestern Energy Group, Inc. (NASDAQ: NWE) to Black Hills Corp. for 0.98 shares of Black Hills for each share of NorthWestern is fair to NorthWestern shareholders. Upon completion of the proposed transaction, NorthWestern shareholders will own approximately 44% of the combined company.

The investigation concerns whether NorthWestern and its board of directors violated the federal securities laws and/or breached their fiduciary duties to shareholders by failing to, among other things: (1) obtain the best possible consideration for NorthWestern shareholders; (2) determine whether Black Hills is underpaying for NorthWestern; and (3) disclose all material information necessary for NorthWestern shareholders to adequately assess and value the merger consideration.

On behalf of NorthWestern shareholders, Halper Sadeh LLC may seek increased consideration for shareholders, additional disclosures and information concerning the proposed transaction, or other relief and benefits. We would handle the action on a contingent fee basis, whereby you would not be responsible for out-of-pocket payment of our legal fees or expenses.
