Simplify's Take
What believers are saying
- FY2026 revenue hit $1.518 billion, up 40%, with 21.0% Q3 operating margin.
- July 2026 SHIELD-6G funding deepens VIAVI's role in European 6G security research.
- August 2026 Vertex 6.0 and AI Experts extend momentum into 6G, Wi-Fi 7, and AI labs.
What critics are saying
- January 2026 restructuring cuts 5% of staff, proving management still needs cost surgery.
- Traditional telecom spending stays cyclical; FY2026 growth leaned on Spirent and AI infrastructure demand.
- Stock-based compensation, leverage, and a $557 million equity raise dilute holders and compress returns.
What makes Viavi Solutions unique
- VIAVI owns compliance-test franchises for PCIe 6.0, Ultra Ethernet, and 6G channel emulation.
- Spirent acquisition added $145 million FY2026 revenue and deepened network test breadth.
- VIAVI bridges wireless, optical, aerospace, and defense testing with one integrated platform stack.

↑ 6%VIAVI Solutions has introduced Vertex 6.0, the industry's first channel emulator designed for 6G and Wi-Fi 7/8 testing. The platform features 400 MHz instantaneous bandwidth and supports carrier frequencies up to 23.6 GHz. Vertex 6.0 extends VIAVI's wireless portfolio by recreating real-world RF propagation conditions in laboratory environments. It represents the first Vertex upgrade following VIAVI's acquisition of Spirent Communications' high-speed Ethernet, network security and channel emulation testing business. Each 6U Vertex chassis supports 36 RF ports, 256 digital links and up to 1.6 GHz of bandwidth. The platform provides emulation for cellular, Wi-Fi, military and aerospace RF technologies, supporting configurations from 2x2 up to 8x8 for Wi-Fi applications.
Paul McNab, executive vice president and chief marketing and strategy officer at Viavi Solutions, sold 1,595 shares of the company on 10 August 2026 for approximately $60,000, according to an SEC Form 4 filing. The shares were sold at $37.37 each, slightly above the $37.20 closing price on the transaction date. Following the sale, McNab retains 13,876 directly held shares. The transaction reduced his direct position by 10%. Viavi Solutions provides network testing, monitoring, and assurance solutions to telecommunications providers, enterprises, and government organisations globally. The company operates through three segments: Network Enablement, Service Enablement, and Optical Security and Performance Products. At market close on 10 August 2026, Viavi had a market capitalisation of $8.7 billion.
StockStory analysed three cash-producing stocks, recommending investors avoid two while highlighting one with stronger prospects. Allegro MicroSystems faces end-market challenges, with flat sales over two years and operating margin falling to 2% over five years. The power management chip designer trades at 37.6x forward P/E. Viavi Solutions showed weak performance with 3.4% annual growth over five years, whilst earnings per share remained flat despite revenue growth. The telecommunications testing company trades at 26.2x forward P/E. Merck emerged as the recommended stock, boasting a 21.5% trailing 12-month free cash flow margin. The pharmaceutical company's portfolio includes the blockbuster cancer immunotherapy Keytruda. The analysis emphasises that strong cash flow alone doesn't guarantee superior returns without efficient capital allocation.
VIAVI Solutions has been awarded $1.1 million in funding from the European Smart Networks and Services Joint Undertaking and Horizon Europe to advance the SHIELD-6G project. The company will develop digital twins using its TeraVM AI RAN Scenario Generator, enabling AI-driven security models to be tested before commercial 6G networks launch. The SHIELD-6G project aims to create a comprehensive AI-driven cyber threat intelligence platform for 6G networks. VIAVI will use its technology to simulate, detect and analyse potential threats across network environments. VIAVI joins a European consortium coordinated by University College Dublin, working alongside Ericsson, Nokia, Thales and network operators Telefónica and LMT of Latvia. SHIELD-6G is part of Horizon Europe's initiative to accelerate European 6G research, which selected 20 new projects.
Viavi Solutions shares have surged 167.9% year to date, outpacing the industry's 150.2% growth and competitors Keysight Technologies (72.3%) and Ciena (109.7%). The company is benefiting from strong demand in AI infrastructure, particularly in its Network and Service Enablement segment. Recent innovations include the industry's first Ultra Ethernet Transport validation solution for AI fabrics and AI Experts, an AI-driven software layer for testing platforms. Viavi also secured PCIe 6.0 Certification and acquired Spirent's high-speed Ethernet business, expanding its customer base and capabilities. Operating margins improved to 21% in Q3 fiscal 2026 from 16.7% year-ago, whilst revenue grew 42.8% and non-GAAP operating income increased 79.2%. The company expects further margin expansion in Q4.
