Coles Group reported 2.5% sales growth and 10.2% EBIT growth in 1H26. The key driver of earnings was higher gross profit margins, which should persist in 2H26e, but then fade in future years. Cost savings and productivity benefits from its supply chain investment are also boosting profit margins. Coles sales trends have slowed highlighting the Woolworths DC strike benefit was transitory. However, its growth still outstripped Woolworths on a two-year basis. Coles has de-rated over the past month and its sales momentum is likely to converge with Woolworths over the next 3-6 months.
