Telecom shares (NZX: TEL) were down 2.17% to $2.25 in mid afternoon trading, breaking out of their 52-week band ($2.26-$2.88).

Yesterday, the companies shares were down one cent for most of the session, but crashed a further five during the telco's XT briefing, during which $10 million compensation was announced.

Before the January 27-29 XT outage hit, kicking off the telco’s latest round of mobile grief, its shares had been trading at $2.44 - already well-off their 52-week high of $2.88. 

Yesterday, at a briefing to announce Telecom’s $10 million compensation offer for those affected by this week’s outages, chief executive Paul Reynolds reiterated that XT outage-related costs would push Telecom’s 2010 profit toward the lower end of its $400 million to $440 million ebitda guidance.

Forsyth Barr analyst Guy Hallwright today “shaded down” his Telecom ebitda estimate from $410 million to $403 million.

Mr Hallwright estimates problems with XT could throw Telecom’s customer acquisition target six months behind schedule.
