Companies whose shareholders reject takeover bids because the purchase price is too low typically end up being purchased at a later date for higher prices.
Obviously it's possible that this does not happen. However, assuming such a bid does take place it will likely be above the $14.30 offer made months ago.
I suspect ALCS will get an offer of at least $16-18 which will get approved by shareholders. That's not bad premium in the short term. Would make for a Greta arbitrage play. I believe the agreement with Argonne stipulated that there would be a termination fee only if the company was sold to a third party within one year of its big being rejected.
