How is employer stock worked into a 401(k) takeover? While moving the assets from one plan admin to a new plan admin, how is the stock handled?

With a great deal of care.

Is your question with respect to a corporate transaction in which the acquiring company purchases 100% of the outstanding shares of the corporate sponsor maintaining a 401(k) plan, in which some plan assets are held in employer stock?
