New debt facility - €825 million refinancing in place to underpin growth

SigmaRoc plc, Europe's leading lime and minerals group, announces that, further to the indications given in our 2025 results RNS, it has signed and closed an agreement to refinance its principal banking arrangements with an increased facility of up to €825 million on investment grade terms together with a €300 million uncommitted accordion.

The facility delivers significant additional capacity based on a new 5-year revolving credit facility (RCF), an unsecured structure, a 100bps improved margin profile over EURIBOR for all margin brackets and more flexible covenants. The facility is aimed to support the funding of the existing business and future acquisitions.

Jan van Beek, CFO, commented:

"We are delighted to have secured this facility with a consortium of leading banks. The offer was oversubscribed and adds to SigmaRoc's ability to grow its business, lowers funding costs, allows flexibility in decision-making and ultimately, simplifies the capital structure of the group. We thank all of the banks involved for their support."

Information on the Company is available on its website, www.sigmaroc.com.
