Monitor the shareholder vote outcome closely — the May 26 deadline suggests the special meeting is imminent. If the merger is approved, STEL shares will convert to PB shares at the agreed ratio; if rejected, STEL could trade down on deal-break risk. The 78% analyst bullishness on STEL suggests the market expects approval, but the active solicitation campaign indicates management is working to secure votes.
