MKS Inc. sells Ophir Optics to TTM Technologies for $650m

MKS Inc. (NASDAQ: MKSI) has signed a definitive agreement to sell its Ophir Optics business to TTM Technologies for $650 million in cash, subject to customary closing adjustments. The purchase price represents a multiple of more than 18x the unit's projected FY 2026 adjusted EBITDA, according to the company. The transaction is expected to close in the second quarter of 2027, pending regulatory approvals and other customary conditions.

Ophir Optics supplies high-precision infrared thermal imaging and laser optics systems to customers across defence, security and industrial markets. TTM Technologies, the acquirer, is a global manufacturer of printed circuit boards, RF components, microwave assemblies and mission-critical systems, making Ophir a complementary fit for its advanced electronics portfolio.

The deal

MKS president and chief executive John T.C. Lee framed the divestiture as a balance-sheet strengthening move rather than an exit from optics entirely. "This transaction represents an opportunity for MKS to capitalise on the value we've created with the Ophir Optics business and further strengthen our balance sheet," he said, adding that TTM is well positioned to support the next phase of the unit's growth.

Notably, the transaction does not include the separately operated Ophir Instruments business, which makes laser power measurement and beam profiler products, nor does it transfer the Ophir brand itself. MKS says customers of Ophir Instruments will see no change to products, services or support. J.P. Morgan Securities is acting as exclusive financial adviser to MKS; Herzog Fox and Neeman is lead legal counsel.

Market context

The deal reflects a broader pattern of semiconductor and photonics conglomerates streamlining their portfolios around core process-control and advanced-packaging capabilities. MKS has been building out its semiconductor manufacturing and electronics-packaging technology stack, and the Ophir Optics unit, while profitable at an implied EBITDA margin that justifies an 18x-plus multiple, sits in the defence and specialty industrial segment rather than in the advanced chip-fabrication supply chain where MKS is investing most heavily.

For TTM Technologies, the acquisition adds precision optical content to an existing RF and interconnect franchise that already serves defence primes and government customers. Infrared optics and thermal imaging are in sustained demand across defence electronics programmes, driven by increased procurement budgets in the US, Europe and Asia-Pacific. That demand environment is likely to underpin the business's growth trajectory under new ownership.

Regulatory and financial considerations

The deal structure is all-cash with no share component, limiting integration complexity. Regulatory consents are required, and given that the target serves defence and security end markets, relevant government permit processes may extend the timeline toward the later end of the expected Q2 2027 window. MKS disclosed the EBITDA multiple using a non-GAAP adjusted figure and noted it cannot provide a full GAAP reconciliation due to the difficulty of estimating items such as intangible amortisation and restructuring charges. Investors should treat the headline multiple with that caveat in mind.

With the divestiture proceeds, MKS is positioned to reduce the debt load it accumulated through prior acquisitions, most significantly its 2022 purchase of Atotech. The company's ability to deploy capital back into its semiconductor and electronics-packaging core will be a key metric for analysts watching whether the strategic refocus translates into improved operating leverage over the next two to three years.
