Pinned straw:
I'm not following this one as deeply as I used to, and won't be revisiting the results for a while yet. So I'm going to shoot from the hips on my interpretation of what has happened.
The company has admitted that it has been highly dependent on discounting, which is not sustainable, and now requires a complete pivot to the strategy.

They've bulk discounted their way to "success", by offering aggressively discounted bulk deals during the multiple sales periods during the year. In this set of results, they've ceased reporting "average revenue per item" and "items per order".

All the while, the number of new and returning customers have been stagnant for the past 4-5 years.

During the conference call this morning the CEO disclosed that in FY25, 63% of revenue occurred during the sales period. Up from 35% in FY24! Wowwweee!
Despite the dire FY26 EBITDA guidance of $10-12m (down from $17.4m), I wouldn't rule out further downgrades.
Why? Only 37% of FY25 revenue came outside sale periods. STP has conditioned customers to wait for heavy discounts, and management now plans to unwind that behaviour in FY26. That transition could be painful - especially if upcoming sale events offer thinner discounts as expected and shoppers stay away.
