The manager says he needs to know more about the new company’s dividend policy and structure before he decides what to do with his position.
"It’s got quite a long way to go on this," he said. "It’s fraught with political problems. I think it will go ahead but it will take a while."
The share price of French-listed EADS also took a hit, losing 10 per cent of its value on the news.
Invesco’s £894.9m European Equity fund, run by Jeffrey Taylor, holds nearly 3 per cent in the company.

Mike Jennings, co-manager of the £51.8m Premier Global Strategic Growth fund, also has a significant position in EADS.
He says he was disappointed by today's announcement and more than halved the fund's exposure to EADS this morning because he thought the move was “illogical” for the aerospace company.
In a recent FE Trustnet article, Jennings and co-manager Jake Robbins highlighted the aerospace industry as one of their biggest sector bets.
Jennings and Robbins will review their remaining holdings in the stock over the next several days.
"[The announcement] dilutes my enthusiasm for owning EADS," Jennings said. "When the news broke yesterday we had to read it twice because the logical move would have been for BAE to buy EADS’ defence business off of them."
"So we would have expected the opposite of this. That would have seemed a logical move for both of them and I would have expected the stocks to have rallied on the back of that."
Jennings says the firm had a strong commercial proposition in Airbus and claims the move would "diversify the company away from a strong commercial story to a very uncertain defence story".
