Morgans analyst Alexander Lu said:
WOW delivered a solid 1Q27 sales trading update.
In our view, while trading conditions remain challenging in NZ Food and BIG W, the core Australian Food business (~88% of group EBIT) continues to perform well, supported by improved execution and sustained sales growth ahead of the market.
While we expect this momentum to continue, WOW is now trading on 28x FY27F PE with a yield of 2.7%.
As a result, we see limited upside from current levels, with the valuation largely reflecting the growth outlook.
