We’re proud of the progress we’ve made, from building deeper operational excellence around established names in the roofing industry to bringing new rainware and accessory brands into the OmniMax family. We see this next step as an opportunity to continue strengthening the value we deliver to customers together with Gibraltar. We look forward to working with the Gibraltar team to complete the transaction and build a strong future together.”
