Whispir received a non-binding indicative offer from Zipline Cloud, trading as Pendula, to acquire all its shares or main undertaking.
The offer would be made through a scheme of arrangement or combination of cash and stock, with the proposal expected to be higher than a previous offer made by Soprano Design Technology of 48 cents per share.
Whispir's board warned shareholders that while Pendula has stated its intent, there is no certainty a binding offer will be made.
The board is evaluating Pendula's letter of intent and advised shareholders to take no action regarding Soprano's offer.
