FRANKFURT, May 7 (Reuters) - Heidelberg Materials

will start providing more transparency to investors

around its U.S. business before any possible structural steps,

such as a local listing, its CEO Dominik von Achten told

analysts on Tuesday.

Heidelberg Materials in February floated the idea of a U.S.

listing for its local operations to address a valuation gap with

Europe.
