As disclosed by the Company in the 8-K filed with the SEC on July 9, 2019:

 

On July 8, 2019, Acacia Communications, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Cisco Systems, Inc., a California corporation (the “Parent”), and Amarone Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of the Parent (the “Merger Sub”). The Merger Agreement provides, subject to its terms and conditions, for the acquisition of the Company by the Parent at a price of $70.00 per share of the Company’s common stock, $0.0001 par value per share (each, a “Share”), in cash, without interest and subject to deduction for any required withholding tax (the “Merger Consideration”), through the merger of the Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of the Parent. The Company’s Board of Directors (the “Board”) has unanimously approved the Merger and the Merger Agreement and recommended that stockholders adopt the Merger Agreement, and the Company has agreed to hold a stockholders’ meeting to submit the Merger Agreement to its stockholders for their consideration.

 

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”):

 

·      each Share that is issued and outstanding immediately prior to the Effective Time (other than Shares held in the treasury of the Company or owned by the Parent or any direct or indirect wholly owned subsidiary of the Company or subsidiary of the Parent immediately prior to the Effective Time (all of which will be canceled) and Shares held by holders who properly exercise their appraisal rights under Delaware law) will be automatically converted into the right to receive the Merger Consideration;

 

·      each Company stock option that is outstanding, vested and unexercised immediately prior to the Effective Time will be canceled and converted into the right to receive in cash the excess, if any, of the Merger Consideration over the exercise price per share of such stock option; provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the Merger Consideration, such stock option will be canceled, without any consideration being payable in respect thereof and have no further force or effect;

 

·      each Company stock option that is outstanding and unvested immediately prior to the Effective Time will be canceled and converted into the right to receive in cash the excess, if any, of the Merger Consideration over the exercise price per share of such stock option to the extent, and at the applicable times, such unvested option would have become vested under the vesting schedule in place for such option immediately prior to the Effective Time, including under the terms of the Company’s Amended and Restated Severance and Change in Control Benefits Plan (the “CIC Plan”) and any scheduled retention

agreement after giving effect to any applicable employment offer documents received from the Parent; provided that, in the event that the exercise price of any such unvested stock option is equal to or greater than the Merger Consideration, such stock option will be canceled, without any consideration being payable in respect thereof and have no further force or effect;

 

·      each Company restricted stock unit (“RSU”) and performance-based restricted stock unit (“PSU”) that is outstanding and vested and has not been settled immediately prior to the Effective Time will be canceled and converted into the right to receive the Merger Consideration; and

 

·      each RSU and PSU that is outstanding and unvested immediately prior to the Effective Time will be canceled and converted into the right to receive the Merger Consideration to the extent, and at the applicable times, such unvested RSU or PSU would have become vested under the vesting schedule in place for such RSU or PSU immediately prior to the Effective Time, including under the terms of the CIC Plan and any scheduled retention agreement after giving effect to any applicable employment offer documents received from the Parent.

 

The Merger Agreement contains customary representations and warranties from both the Company, on the one hand, and the Parent and the Merger Sub, on the other hand. It also contains customary covenants, including covenants providing for each of the Company and the Parent to use its reasonable best efforts to cause the Merger to be consummated, subject to certain limitations, and covenants requiring the Company, among other things, (i) to use commercially reasonable efforts to conduct its business in the ordinary course during the interim period between the execution of the Merger Agreement and the Effective Time, (ii) not to engage in specified types of transactions during such period and (iii) not to solicit proposals or engage in discussions relating to alternative acquisition proposals or change the recommendation of the Board to the Company’s stockholders regarding the Merger Agreement, in each case except as otherwise permitted by the Merger Agreement, including in connection with the compliance by the Board with its fiduciary duties under applicable law.

 

(d)           No other person is known by the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any Shares that are beneficially owned by the Reporting Persons.
