Bunnings store tour and management presentation provided plenty of initiatives the retailer is pursuing to grow sales and margins, despite its large market share and high return on capital. Bunnings sales per square metre is less than half US peer Home Depot. Bunnings will add product ranges like auto, solar and cleaning to lift sales productivity. The company is positioned for margin expansion when the building sector recovers. For each 1% sales improvement, EBT could rise by 2.3% on our estimates. Bunnings also has margin upside from retail media, which could add $100-200 million in EBT over time.
