Spirent Communications PLC (LSE: SPT)

Spirent Communications PLC (LSE: SPT) is an FTSE 250-listed provider of automated test and assurance solutions for next-generation devices and networks. This Report covers the Key Recommendation Rationale, Conclusion, and Recommendation on the stock.

Key Recommendation Rationale – Sell at GBX 199.00

• Resistance near Current levels: SPT’s stock price has approached Resistance (R1) which was stated in the previous report on 01 April 2025 therefore, there can be a possibility of a decline from resistance levels. Considering the market conditions and the price action, it is prudent to exit the stock.
• Slower Momentum in Lifecycle Service Assurance Segment - Despite overall revenue growth, the Lifecycle Service Assurance segment experienced a 2% decline, attributed to slow adoption of 5G Standalone by operators and increasing commoditisation in device testing services. This signals that parts of Spirent's portfolio may be more exposed to delays in telecom infrastructure upgrades, potentially affecting medium-term growth unless offset by decent demand in other segments.
• Heavy Reliance on Emerging Technologies for Growth - Spirent’s recent gains, particularly in Networks & Security, appear closely tied to demand for high-speed Ethernet solutions and Positioning systems, driven by sectors like AI data centres and defence. While this diversification is encouraging, it also indicates that the company’s revenue trajectory may be dependent on sustained investment in these fast-evolving, high-tech areas, which are themselves sensitive to macroeconomic conditions and budgetary shifts.
