The exceptional costs -- including IT, customer response lines and other charges associated with the attack -- totalled between £40 million and £45 million. The remaining £15 million is attributed to trading losses. It's not all doom and gloom for the company, though: revenues grew by 1.8 percent and 489,000 customers accepted TalkTalk's offer of a free upgrade, which it believes helped raise consumer confidence and ultimately stopped some customers from leaving.
While TalkTalk's operations have largely been "dominated by the cyber attack," investors are positive that the company has put the worst behind it. That's led to a small rise in TalkTalk's share price, which plummeted following the October announcement and hasn't really recovered since. With BT currently the subject of a regulatory review, TalkTalk believes decisions could go in its favour, allowing it to capitalize on its position as "the value for money telecoms provider" in the UK market.
