There's no trace of a scheduled earnings announcement except for an Investopedia article. There's not even an announcement on their own site!
That will surely piss off the stockholders they do have. Are they trying to hide from the media? Good luck, word will still get around about the terrible Q4 results. Sears execs obviously don't know about how media works. They will get their information regardless.
I'm not too surprised that it falls on the same day that the big layoffs are supposed to happen. Usually layoffs and big changes take place on or very close to the day earnings are announced.
