Adobe has been subject to quite a bit of takeover speculation lately, though nothing has materialized. This reminds me of the chatter going around with IMAX, the stock is just a yoyo...
The company stated:
"Adobe recommends rejection of below-market tender offer from TRC Capital. Adobe has been notified of an unsolicited "mini-tender" offer by TRC Capital to purchase up to 3M shares. Adobe does not endorse TRC's offer and recommends that Adobe stockholders do not tender their shares in response to the offer because it is a mini-tender offer at a price below the current market price for Adobe shares and is subject to numerous conditions. "
