Avista Corporation and Hydro One Limited are both regulated electricity and natural gas companies, and if the merger just proposed goes through, they will together become one of the largest regulated utilities in North America, serving Ontario, Washington, Oregon, Idaho, Montana, and Alaska. But the complaint for this class action claims that shareholders are not being given enough information to assess the deal. The complaint alleges the Proxy does not provide enough information about key inputs and assumptions underlying analyses. Further, where non-GAAP measures are used, the Proxy does not provide comparable GAAP measures or the line-item metrics used to calculate them.
