There is actually nothing concrete happening tomorrow, other than Landstar should officially be gone and Data443 should no longer have any mention of shell. I don't believe they can even request a ticker change until after the merger is complete (which is tomorrow, so theoretically, they could request tomorrow).
All the other stuff about financials and the like is just speculation because the last financials had revenue listed as "-", so many assumed they were waiting for the merger completion to release that. Will it happen, no one really knows. But ridding themselves of Landstar (except for the ticker) is a big step to being able to fully disclose things.
All just my opinion.
