Cogeco is accusing Rogers and Altice of engaging in “bad faith tactics,” including announcing their $10.3-billion takeover offer without disclosing that Cogeco had already rejected it. Rogers and Altice sent Cogeco a letter accusing the latter’s board of having “failed to fulfill their most basic duties” by turning down the takeover offer within one day after receiving it. (The Logic)

Talking point: When Rogers first went public with its takeover bid earlier this month, it was all smiles. The telcom praised the Audet family, which controls Cogeco, and offered an $800-million premium to the family if it would agree to sell. Cogeco’s letter is reportedly atypically terse for the firm. It came after the missive from Rogers, which has spent the past few weeks repeatedly saying it wants to buy Cogeco despite the rejection from that company’s board. Earlier this week, Cogeco CFO Patrice Ouimet said his firm is looking at offering wireless services to compete directly with Rogers, and is looking to make more acquisitions in the U.S.
