Feb 5 (Reuters) - Dublin-based building materials

supplier CRH's UK unit intends to sell about 171.6

million ordinary shares in SigmaRoc, exiting its entire

15.4% stake in the British quarrying company, a bookrunner said

on Wednesday.

In 2023, CRH sold its European lime operations, including

sites in Ireland, the United Kingdom, Germany, the Czech

Republic and Poland, to SigmaRoc for $1.1 billion.

Following CRH's stake exit, Fidelity Management & Research

Company LLC with 58.3 million ordinary shares would become the

largest shareholder in SigmaRoc, as per data from LSEG.
