2. Historical Background

Viavi Solutions Inc. (NASDAQ: VIAV) boasts a rich and complex history, deeply intertwined with the evolution of the telecommunications industry. Its lineage traces back through a series of mergers and acquisitions, most notably stemming from the formation of JDS Uniphase Corporation (JDSU), and culminating in its current identity as a leader in network test, measurement, and optical technologies.

The foundation of Viavi's heritage lies in two distinct pioneering companies:

• Uniphase: Founded in 1979 in a San Jose, California garage, Uniphase began as a manufacturer of lasers for chip makers and scanners.
• JDS Optics: Established in 1981 in Ottawa, Ontario, by Jozef Straus, Philip Garel-Jones, Gary Duck, and Bill Sinclair. This company later became JDS Fitel through a partnership with Fitel, specializing in fiber optics and optical connectors.

The pivotal early milestone was the 1999 merger of JDS Fitel and Uniphase Corporation, which gave birth to JDS Uniphase Corporation (JDSU). This merger created a formidable entity in the burgeoning fiber optic communication and test equipment market, poised to capitalize on the dot-com bubble's enthusiasm for optical components. JDSU experienced rapid growth and embarked on an aggressive acquisition strategy during this period.

However, the telecom bust of the early 2000s brought significant challenges, leading to substantial write-downs, business losses, and a dramatic reduction in workforce for JDSU. Despite these headwinds, the company continued to strategically evolve through key acquisitions that bolstered its test and measurement capabilities:

• In 2005, JDSU acquired Acterna for $760 million. Acterna, itself a product of the 2000 merger of Wavetek Wandel Goltermann (WWG) and TTC, brought extensive expertise in network testing and advanced optical test instruments, significantly strengthening JDSU's position in this sector.
• In 2013, JDSU further expanded its network performance management offerings by acquiring Network Instruments for $200 million, adding products like Observer GigaStor to its portfolio.

The most transformative event in the company's recent history occurred in August 2015, when JDS Uniphase Corporation executed a strategic split into two independent, publicly traded companies:

1. Viavi Solutions Inc. (NASDAQ: VIAV): This new entity inherited JDSU's Network Enablement (NE), Service Enablement (SE), and Optical Security and Performance Products (OSP) businesses. Its focus was squarely on network test, measurement, and assurance technology, alongside optical technology for diverse applications such as anti-counterfeiting and 3D motion sensing.
2. Lumentum Holdings Inc. (NASDAQ: LITE): This company comprised JDSU's former Communications and Commercial Optical Products (CCOP) division, concentrating on optical networking, laser materials processing, biotechnology, and 3D sensing.

This separation was designed to create more focused and agile companies, better equipped to pursue distinct market opportunities. Following the split, JDSU was renamed Viavi Solutions Inc., with its shares commencing trading under the ticker VIAV on August 4, 2015. Richard Belluzzo served as interim CEO before Oleg Khaykin was appointed President and CEO.

Since the 2015 spin-off, Viavi Solutions has continued its trajectory of transformation and growth:

• Next-Generation Network Focus: Viavi has remained at the forefront of developing solutions for emerging technologies like 5G, 6G, and hyperscale data centers, introducing 400G test solutions and actively participating in 6G and AI research, including the development of a 6G city-scale digital twin.
• Strategic Acquisitions: The company has continued to bolster its portfolio with targeted acquisitions, such as Jackson Labs Technologies (enhancing its Position, Navigation, and Timing capabilities crucial for 5G and defense) and, more recently, Spirent Communications' High-Speed Ethernet Network Security and Channel Emulation Testing Business.
• Headquarters Relocation: A strategic move saw the company relocate its corporate headquarters from Milpitas, California, to Chandler, Arizona, signaling a commitment to future growth and expansion of manufacturing facilities.
• AI and Automation: Viavi is heavily investing in AI-driven solutions to enhance network management, aiming for greater efficiency, agility, and intelligence in network operations, pushing towards predictive and semi-autonomous networks.

Viavi Solutions Inc. today leverages this deep legacy of innovation, tracing its roots back over a century through its acquired entities, to drive advancements across critical technological frontiers, from fundamental radios to advanced 5G networks and sophisticated 3D sensing applications.
