Woolworths reported a strong improvement in profit margins in 1H23 driven by its Australian Food segment. COVID-19 costs have unwound and cost efficiency programs are delivering results. We expect further margin gains in 2H23e, albeit at a smaller rate. The challenge for Woolworths is its profit margins will be close to long-term averages by the end of FY23e and EPS growth may step down to single-digits in FY24e and beyond.
