ValueAct’s investment is still less than 5% of American Express, Bloomberg reported citing unnamed sources.

However, American Express is not a core active target of ValueAct and the fund could sell the stake if it decides against a longer-term campaign for changes.

The move comes as the US-based card issuer struggles with its loss from various co-branded partnerships.

American Express said in a statement: "ValueAct is a well-respected firm. We have been speaking with them, as we do with other investors, and look forward to continuing a constructive dialogue.
