Yes to my knowledge any warning should have issued prior to now (30 days prior to results), certainly not an expert in this but from memory that's the rule with regards to missing guidance but only if it is expected to differ by more than 10% to previously guided expectations.
I don't recall a particular guidance number, if none is given I would expect last years numbers would have to be use as a proxy?
Either way results must therefor most definitely be a profit for the half and no dividend is going to be paid so balance sheet should improve even further.
I'm not expecting great results but unlike others I don't see David Jones doing badly as a foregone conclusion that MYR is doing badly, that logic is flawed IMO as if one of the companies changes tack and gains more traction the customers and sales they pick up must come from somewhere, most logical place would be the most similar business to them previously IMO.
MYR were closing stores, rationalizing their ranges, cutting costs and reinvigorating their customer service focus, essentially a blueprint for what David Jones is now saying it will do, good chance that is driven by losing market share to competitors.

Ps: so in essence I'm calling for an out-performance of David Jones results, HOWEVER, this does not necessarily mean profit growth, likely just less decline, I'm not obtuse to how poor the retail industry in general is performing, considering I was picking the retail industry as the turnaround story in 2019 I think it's fair to say I have a pretty good idea how badly retail is doing, I think my position is right but timing was out by 12-18 months
