What the Analysts think about Spirent
Analyst ratings (Buy, Hold, Sell) for Spirent stock.
Bulls say / Bears say
Spirent’s H1 2025 results were resilient, with revenue up 5% to $208.1m, order intake and the order book both up 9%, reflecting strong demand across its offerings despite macroeconomic headwinds.
Spirent and Keysight together control 85% of the high-speed Ethernet testing market, over 60% of the network security testing market, and more than 50% of the radio frequency channel emulation market, demonstrating Spirent’s leading competitive position in critical segments.
Keysight’s proposed £1.16 billion ($1.57 billion) acquisition of Spirent signals significant strategic value and a premium valuation for Spirent’s automated testing solutions, with investors viewing its growth outlook positively.
The U.S. DOJ’s requirement that Keysight divest Spirent’s high-speed Ethernet, network security, and RF channel emulation units before completing the acquisition may break up Spirent’s core businesses and disrupt its integrated test and assurance solutions.
Spirent’s H1 2025 results show Revenue from Lifecycle Service Assurance dropped 2% year-on-year to $83.7m, as a result of slow 5G Standalone upgrades and increasing commoditization in device testing, indicating challenges in a key segment.
The same H1 2025 report shows a reported operating loss of $14.2m, up 53% compared to H1 2024, and a reported loss before tax of $12.8m, a 71% increase year-on-year, underscoring unstable profitability despite higher revenues.
