In its recent blog post, VentureCaseLaw covers a 2015 Delaware decision and how Delaware law deals with appraisal in instances where a Company has drag-along rights. In summary:

Venture-backed companies should not assume an implied waiver of minority appraisal rights in a merger that utilizes a voting agreement’s drag-along rights if procedural requirements are not followed. When a waiver of appraisal rights has procedural requirements, they need to be followed or eliminated via an amendment. Alternatively, the drag-along can require minority stockholders to explicitly approve the sale, instead of having the sale be de facto valid without their signatures given the drag-along.
