Coherent Confirms Receipt of Unsolicited Proposal from MKS Instruments

SANTA CLARA, CA, February 8, 2021 – Coherent, Inc. (NASDAQ: COHR) (“Coherent”) today announced that it has received an unsolicited acquisition proposal from MKS Instruments, Inc. (NASDAQ: MKSI) (“MKS”) to acquire Coherent in a cash and stock transaction. Under the terms of MKS’ proposal, each share of Coherent common stock would be exchanged for $115.00 in cash and 0.7473 of a share of MKS common stock at the completion of the transaction, subject to customary closing conditions including receipt of U.S. and foreign antitrust approvals and stockholder approvals. ​

On January 19, 2021, Coherent announced that it had entered into a merger agreement with Lumentum Holdings Inc. (NASDAQ: LITE) (“Lumentum”) pursuant to which Lumentum agreed to acquire Coherent and each share of Coherent common stock would be exchanged for $100.00 in cash and 1.1851 shares of Lumentum common stock at the completion of the transaction, subject to customary closing conditions including receipt of U.S. and foreign antitrust approvals and stockholder approvals.

Coherent’s board of directors is evaluating MKS’ proposal and has not made a determination as to whether it is superior to the Lumentum transaction under the terms of Coherent’s merger agreement with Lumentum. After consulting with its financial and legal advisors, however, Coherent’s board of directors has determined that MKS’ proposal could lead to a transaction that is superior to its pending transaction with Lumentum and, accordingly, Coherent has determined to engage in discussions with MKS to further evaluate the comparative benefits and risks of MKS’ proposed transaction relative to Coherent’s pending transaction with Lumentum, including the near and long term financial opportunities of each transaction, the expected completion timing of each transaction, and the closing risks associated with each transaction. There can be no assurances that Coherent will conclude that the transaction proposed by MKS is superior to Coherent’s pending transaction with Lumentum and Coherent investors are encouraged to await a final determination from Coherent’s board of directors.

Notwithstanding its receipt of MKS’ proposal and pending discussions between Coherent and MKS, Coherent’s board of directors continues to recommend Coherent’s merger agreement with Lumentum to its stockholders. Coherent’s board of directors is not modifying or withdrawing its recommendation with respect to the Lumentum merger agreement and the Lumentum merger at this time, or proposing to do so, and is not making any recommendation with respect to MKS’ proposal at this time.

Bank of America is serving as financial advisor to Coherent and Skadden, Arps, Slate, Meagher & Flom LLP is serving as legal advisor.

Important Information and Where You Can Find It

In connection with the proposed transaction between Coherent and Lumentum (the “Proposed Transaction”), Lumentum plans to file with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 that will include a joint proxy statement of Coherent and Lumentum and will constitute a prospectus with respect to shares of Lumentum’s common stock to be issued to Coherent’s stockholders at the completion of the Proposed Transaction (the “Joint Proxy Statement/Prospectus”). Coherent and Lumentum may also file other documents with the SEC regarding the Proposed Transaction. This communication is not a substitute for the Joint Proxy Statement/Prospectus or any other document which Coherent or Lumentum may file with the SEC in connection with the Proposed Transaction.
