Introductory Note

On March 1, 2021, Acacia Communications, Inc., a Delaware corporation (the “Company”), completed its previously announced transaction to be acquired by Cisco Systems, Inc., a Delaware corporation (previously a California corporation until its reincorporation in Delaware) (“Parent”) pursuant to the Amended and Restated Agreement and Plan of Merger (the “Amended and Restated Merger Agreement”), dated as of January 14, 2021, by and among the Company, Parent and Amarone Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Amended and Restated Merger Agreement, Merger Sub merged with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Parent (the “Merger”).

Item 2.01. Completion of Acquisition or Disposition of Assets.

On March 1, 2021, the Merger was consummated and, in accordance with the Amended and Restated Merger Agreement, each share of the Company’s common stock (the “Common Stock” and each, a “Share”) issued and outstanding as of immediately prior to the effective time of the Merger (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 Parent immediately prior to the Effective Time, all of which were canceled at the Effective Time, and Shares held by holders who have properly exercised and perfected appraisal rights under Delaware law) was automatically converted into the right to receive $115.00 in cash, without interest and subject to deduction for any required withholding tax (the “Merger Consideration”), and each former holder of such Shares ceased to have any rights with respect thereto, except the right to receive the Merger Consideration.

At the Effective Time, each outstanding and unexercised vested stock option, vested restricted stock unit and vested performance stock unit terminated and was converted into the right to receive from Parent an amount of cash, without interest, equal to (i) in the case of each stock option, the excess, if any, of the Merger Consideration over the exercise price of such option, and (ii) in the case of each restricted stock unit and performance stock unit, the Merger Consideration (in each case, the “Cash-Out Amount”), subject to all applicable tax withholding. At the Effective Time, each outstanding and unexercised unvested stock option, unvested restricted stock unit and unvested performance stock unit was converted into and substituted for the right to receive from Parent the applicable Cash-Out Amount for such equity award, payable in accordance with the original vesting schedule of such equity award (including any applicable terms relating to accelerated vesting of the equity award under the terms of the Company’s Amended and Restated Severance and Change in Control Benefits Plan and any scheduled retention agreement, after giving effect to any applicable employment offer documents received from Parent), subject to all applicable tax withholding.

The aggregate consideration paid by Parent in the Merger was approximately $4.5 billion on a fully diluted basis, net of cash and marketable securities. Parent funded the payment of the aggregate consideration through its cash-on-hand.

The foregoing description of the Merger and the Amended and Restated Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Amended and Restated Merger Agreement, which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on January 14, 2021 and is incorporated herein by reference.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In connection with the Merger, the Company notified the Nasdaq Global Select Market (“Nasdaq”) on March 1, 2021 of the consummation of the Merger and requested that Nasdaq file with the SEC an application on Form 25 to delist and deregister the Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Common Stock, which traded under the symbol “ACIA,” will cease trading on Nasdaq prior to the open of trading on March 1, 2021. The Company intends to file with the SEC a certification and notice on Form 15 requesting the deregistration of the Common Stock under Section 12(g) of the Exchange Act and the suspension of the Company’s reporting obligations under Section 13 and Section 15(d) of the Exchange Act.
