ADBRI Limited (ASX:ABC) (Adelaide Brighton) is open to a ­potential merger with its largest shareholder, Barro Group Pty Ltd., but says navigating the housing downturn remains its immediate priority. “We have been clear in the past we do believe there are likely synergies through a combination of Barro assets in concrete, cement and aggregates with the Adelaide Brighton assets,” Adelaide Brighton Deputy Chairman Zlatko Todorcevski told shareholders at its annual general meeting. “However, at this time there are no active conversations and I think it’s probably best left at that”. Investors quizzed the company and Chairman Raymond Barro about their ­intentions, but the Chairman said he was unaware of any push by ­remaining shareholders for a deal to proceed.
