The negotiations have ended (terminated) and the *potential acquirer* may be announced as the final buyer (acquirer) once they accept, sign off, and finish (wind down) what they need to.
You wind down that part of the business being sold as it is transitioned with new ownership. The rest is still up and running.
My intepretation below highlighted with additions:
Atrinsic, Inc. (PINK: ATRN) announced today that it has decided to wind down support for its agency business following(after) the termination of negotiations(once that is accomplished) with a potential acquirer for the business. The company, in consultation with its strategic advisors, is continuing its efforts to maximize the value of its remaining assets(the part not being sold) for all of its stakeholders."
We will know shortly I would think if the company would clarify this obfuscation but I would not hold my breath.
