UNITED KINGDOM (From news reports) -- Graphic Packaging Holding's acquisition of AR Packaging Group AB is under investigation by the United Kingdom's Competition and Market's Authority (CMA).

The CMA is considering if the combination of the two packaging companies will be "expected to result in a substantial lessening of competition within any market or markets in the United Kingdom."

According to the CMA's website, interested parties have until September 1, 2021 to comment on the planned merger.

Graphic Packaging struck a deal in May to acquire AR Packaging Group for $1.45B. AR Packaging is Europe's second largest producer of fiber-based consumer packaging.
