Cisco first announced the acquisition of Acacia in July of 2019. Under the original arrangement, Cisco would pay Acacia shareholders $70 per share, which worked out to about $2.6 billion in total. It seems that Cisco has blinked first. The company announced on Thursday that it had agreed to pay Acacia shareholders $115 per share, or $4.5 billion total, in an amended agreement. Cisco may have avoided a protracted court battle by agreeing to the higher price tag. Now what The acquisition is now expected to be complete by the end of the first quarter of 2021, with CEO Raj Shanmugaraj and all Acacia employees joining Cisco's optics business. "I am delighted that Cisco and Acacia have decided to come together in this mutual deal," Cisco CEO Chuck Robbins said. I'm guessing Cisco is not actually delighted about paying a much higher price for Acacia than it originally agreed to, but it appears the company was anxious enough to close the deal that it was willing to throw in an extra couple of billion dollars. That equates to a nice payday for Acacia investors. 10 stocks we like better than Acacia CommunicationsWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
