WeissLaw is investigating whether TTPH's board of directors acted to maximize shareholder value prior to entering into the acquisition agreement, and whether TTPH shareholders have enough information to cast a fully informed vote on the proposed transaction.  Notably, at least one analyst set a target price of $1.50 per TTPH share, or approximately $1.00 above the per-share consideration.

Moreover, the deal strategic transaction through which ACRX hopes to leverage TTPH's "well-established U.S. salesforce and a high-growth hospital product" to optimize the efficiency of the commercialization of its DSUVIA drug.

Given these facts, WeissLaw is concerned whether the proposed acquisition undervalues the Company, and whether all material information related to the proposed acquisition is fully and fairly disclosed.
