• Agreement to divest Spirent’s high-speed ethernet, network security, and channel emulation business lines

SANTA ROSA, Calif. & LONDON--(BUSINESS WIRE)--Jun. 3, 2025-- Keysight Technologies, Inc. (NYSE: KEYS) ("Keysight") is pleased to confirm that Keysight and Spirent Communications PLC (London Stock Exchange Symbol: SPT) (“Spirent”) have entered into a consent decree with the United States Department of Justice (“DOJ”) in connection with its review of Keysight’s proposed acquisition of Spirent (the “Acquisition”), pursuant to which Keysight and Spirent have agreed to divest Spirent’s high-speed ethernet, network security, and channel emulation business lines (the “Divestment Business”) to VIAVI Solutions, Inc. ("VIAVI") (NASDAQ: VIAV) or another acquirer approved by DOJ. The consent decree is an important milestone that moves the Acquisition one step closer to closing, pending other regulatory approvals and the satisfaction of customary closing conditions.

Pursuant to the settlement process, DOJ has filed in court a proposed settlement (“Proposed Final Judgment”) and an Asset Preservation and Hold Separate Stipulation and Order (“APSO”). Keysight and Spirent have also entered into a short side letter in respect to the settlement process with DOJ (“Side Letter”).

Copies of the Proposed Final Judgment, APSO, and Side Letter will be made available on Spirent and Keysight’s websites at https://corporate.spirent.com/ and https://investor.keysight.com/investor-resources/proposed- acquisition-of-spirent/.

With support and assistance from Spirent, Keysight remains committed to working quickly and constructively with the State Administration for Market Regulation of the People’s Republic of China to obtain clearance for the Acquisition.

Proposed Divestment

In connection with the consent decree, Keysight notes that, on or around the date of this announcement, Keysight and VIAVI have entered into an amendment agreement in respect of the sale of the Divestment Business, pursuant to which Spirent’s channel emulation business line has been added to the scope of the divestiture previously announced by Keysight on March 3, 2025. The sale of the Divestment Business remains subject to closing conditions, including regulatory approvals and completion of the Acquisition. Keysight continues to expect the sale of the Divestment Business to complete shortly after the Acquisition becoming effective.

Timing of the Acquisition

Completion of the Acquisition remains subject to the satisfaction or (if capable of waiver) waiver of the remaining conditions to the Acquisition set out in Part III of the Scheme Document, (the “Conditions”) including the Condition relating to sanction of the Scheme by the Court. Keysight continues to expect that the Scheme will become effective during the third quarter of Keysight’s current fiscal year (period ending July 31, 2025). The parties continue to keep the timetable under close review and will provide any updates as required.

Capitalized terms in this announcement, unless otherwise defined, have the same meanings given to them in the Update on Regulatory Clearances announcement in relation to the Acquisition published on December 2, 2024.
