The deal with Pfizer was hammered out BEFORE the ANDA,(abbreviated new drug application).
Astute investors should know that LABS does not have any existing commercialized drugs registered with the FDA and therefore cannot submit the ANDA. The ANDA was submitted by LABS to the FDA in conjunction with Pfizer, which does have existing commercialized drugs registered with the FDA.
Imho, I believe it will not be a complete take over but rather a tightly controlled joint venture with majority control resting with Pfizer.
Hopefully no one forgot that the horse comes before the carriage as it applies to the ANDA.
