Sure, but no company ever trades at a PE of 10 and maintains that profit for the next year. i.e. if it trades at a PE of 10 at an EPS of 42, the market is expecting EPS to drop in the following year (and in almost all cases the marked is correct). I don't think this applies to DDR. They did have a tailwind from the WFH movement but even prior to this phenomenon DDR was logging strong growth. For it to go from a growth stock to flat earnings is unlikely. I think that mid to high single digit growth can be achieved in the long term simply from a lifting IT spend in the broader industry.

Historically there was one year where the PE was 10 so I guess never say never. I would consider a PE between 14 and 16 bargain basement provided that company reports confirmed mid to high single digit growth. At an EPS of 42cps, this equates to ~$6.30.
It's impossible to predict the SP so I'm certainly not holding my breath for the SP to get that low. I think the only way this will go below $7.50 is if EPS in FY23 comes in lower than FY22.
