Keysight Technologies (US49338L1035) remains one of the larger electronic test and measurement names on the NYSE and is a member of the S&P 500 index, a status that secures it a place in many international equity portfolios. The group has recently attracted attention again after closing the acquisition of UK-based Spirent Communications via a scheme of arrangement, adding network test and assurance capabilities to its communications portfolio.
What the Spirent acquisition adds
The scheme of arrangement for Keysight Technologies to acquire Spirent Communications became effective in 2025, with Keysight now owning the entire issued ordinary share capital of Spirent, according to a regulatory announcement filed in London. Spirent shareholders receive 199.0 pence in cash per share under the agreed terms, while a previously announced 3.5 pence dividend paid on July 23, 2025 is not deducted from the offer price.
Spirent is known for test and assurance solutions in areas such as 5G, cloud, and positioning, which complements Keysight’s existing design and test tools for wireless, aerospace, and data center customers. The combination broadens Keysight’s presence in network emulation and performance testing at a time when operators and equipment makers prepare for 6G and more complex cloud-native architectures.
Analysts see cautious optimism
Beyond M&A, the sell-side view on Keysight Technologies has shifted toward what one analysis describes as "cautious optimism" as the electronic measurement sector recovers from a cyclical downturn that started in late 2024. Analysts cited by Bitget see Keysight as a primary beneficiary of accelerating 6G development, rising AI-driven data center investment, and a renewed upturn in the semiconductor industry, all areas where test intensity tends to be high.
Valuation metrics referenced in that analysis show Keysight’s forward price-to-earnings ratio typically in a 22x to 26x corridor and a price-to-book ratio around 5.5x to 6.0x, which puts the stock roughly in line with or slightly below the broader electronic test and measurement peer group that includes names such as Rohde & Schwarz (unlisted) and Tektronix (part of Fortive). The S&P 500 inclusion and NYSE listing also keep Keysight directly comparable with large US technology hardware and semiconductor equipment stocks in many institutional portfolios.
