“It’s been another great year. I’d like to thank my brilliant Diploma colleagues for their skill, dedication and passion. They make it happen. These strong results demonstrate how we balance ambitious earnings growth and disciplined returns – in good times and bad – to build on our long track record of sustainable quality compounding. We have great momentum going into the new year. The quality and diversity of our portfolio position us well for structural organic growth. Our acquisition pipeline is healthy.
