Order, Supreme Court, New York County (Saliann Scarpulla, J.), entered June 13, 2019, which, to the extent appealed from as limited by the briefs, denied defendants' motion to dismiss the cause of action for breach of contract except for the merger-related claims asserted by plaintiffs Alexa Mateen and Justin Mateen, and the causes of action for tortious interference with contractual relations and tortious interference with prospective economic advantage, unanimously affirmed, without costs.

The court properly found that CPLR 7601 does not apply to bar plaintiffs' claims. CPLR 7601 permits, but does not require, the commencement of a special proceeding to enforce a valuation agreement. Although plaintiffs' claims undoubtedly relate to a dispute over the valuation process, plaintiffs are not seeking to enforce the valuation agreement and are properly seeking relief in a plenary action (see Matter of Penn Cent. Corp. [Consolidated Rail Corp.], 56 NY2d 120, 130 [1982]). In light of the foregoing, the parties' other arguments about the application of CPLR 7601 are moot.

The motion court properly found that issues of fact exist as to whether plaintiffs acquiesced to the transaction at issue. Although plaintiff Rad's unvested options vested immediately upon the merger, and he exercised them all, the equitable defense of acquiescence is "fact intensive, often depending . . . on an evaluation of the knowledge, intention and motivation of the acquiescing party" (Julin v Julin, 787 A2d 82, 84 [Del 2001]).

Contrary to defendants' contention, those plaintiffs whose employment terminated prior to the merger have standing to assert merger-related claims. While they were obligated to sell their outstanding options upon leaving the company, those options were not valued until the merger. Concur—Richter, J.P., Gische, Kapnick, Kern, Moulton, JJ.
