If you and others have not received notification from TECO of the shares being issued and you have a copy of the ratified contract to buy those shares and you purchased those shares with a given purpose which obviously hasn't taken place; a lawsuit is justified.
The lawsuit is probably more costly financially and to all shareholders than it's worth. It's not time yet but when all is said and done; if shareholders eventually collaborated on a class action pending the SEC outcome then the justice or aggravation to those incompetent and/or fraudulent aholes might be worth it. It's so much easier to forgive and forget when one knows the total story. These bits and pieces we receive only to have a zero outcome and additional lost monies is ignorant of the TECO insiders.
TECO'S excuse for a lack of communication with shareholders is now "their attorney's gag order". I believe all "material events" need to publicized by SEC rules so what kind of attorney gags the company from publicizing material events? At the minimum shareholders should be PR'd on the FINRA appeal decision once documented. Six years a shareholder this coming June and I can't believe the saga continues.
