WeissLaw is investigating whether PTLA's board acted to maximize shareholder value prior to entering into the acquisition agreement.  Notably, at least one analyst set a target price of $31.00 per PTLA share, or approximately $13.00 above the per-share consideration.  Additionally, ALXN hopes to leverage the success of Andexxa, PTLA's marquee drug for the treatment uncontrolled bleeding in people taking certain anticoagulants, to improve its market positioning. According to the ALXN's CEO, Andexxa "is well-aligned with [ALXN's] demonstrated expertise in hematology, neurology and critical care."  Finally, ALXN anticipates the addition of Andexxa to its portfolio to be accretive to shareholder value.

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.
