I may be wrong but I understand that use of NOL tax credits are limited if the main propose of the acquisition is to avoid taxes. IRS SEC. 269: ACQUISITIONS TO EVADE OR AVOID TAX
Carry is time limited but a large suitor with a large profitable operation could use the credits before they expire.
I'm not a CPA and have paid way too much in taxes in my life time so could be wrong:-)
