... in Dell and DFC Glob. Corp. v. Muirfield Value P’rs, L.P., 172 A.3d 346 (Del. 2017), the Delaware Supreme Court threw some cold water on the practice of appraisal arbitrage.

In Verition Partners Master Fund, Ltd., et al. v. Aruba Networks, Inc., C.A. No. 11448-VCL, memo. op. (Del. Ch.

As a result, he awarded the dissenters the pre-deal market price of $17.13 per share, a figure significantly below the merger price of $24.67 per share.
