Jeremy Sullivan, investment advisor Hamilton Hindin Greene, said there were some wide estimates as to how much the claims would cost.
He said $50m to $100m for an Australia-wide fix had been talked about, adding FBU was not likely to be “on the hook” for the total.
Market pricing suggests FBU shares, when trading resumes on Monday, could fall to $4.59 - down 21 cents or 4.3 per cent from its last traded price - representing a $164m hit to its market capitalisation.
“Our take is that this is likely to result in a lengthy legal battle,” he said. “I would expect that this may drag on for several years and the final costs will not be known for quite some time,” he said.
Shares in Sky TV rallied by 33 cents (13.3 per cent) to $2.80 after the company said it had started engaging with a potential acquirer, although discussions were at an early stage. Sky said that as such, “there can be no certainty that any transaction will eventuate”.
Sullivan said Sky had been a potential takeover target for a number of years.
News of the approach to Sky came from an announcement regarding its share buyback.
“What that tells me is that Sky, whilst obliged to disclose it, does not feel that it has the legs to go through.”
