FRANKFURT, April 23 (Reuters) - Deutsche Bank DBKGn.DE is expected to announce by Friday at the latest an update on its merger talks with Commerzbank CBKG.DE, which are now in their sixth week, people familiar with the matter said on Tuesday.
The banks are still crunching the numbers behind a possible tie-up, and the chances of striking an eventual deal are at least 50 percent, the people said.
Friday is significant because that is when Deutsche Bank is scheduled to report first-quarter earnings, which are likely to show a 75 percent decline in net profit and a 9 percent decline in revenue, according to a consensus forecast posted on the bank's website.
Last month, Deutsche Chairman Paul Achleitner said the banks would aim to announce more concrete steps on the merger by the time Deutsche published its earnings on April 26.
The banks declined to comment.
The merger talks have come amid stiff resistance from unions and employees, as well as scepticism from some major investors.
