Zacks Industry Outlook Highlights Arista Networks, Corning and TESSCO

For Immediate Release

Chicago, IL – April 28, 2023 – Today, Zacks Equity Research discusses Arista Networks, Inc. ANET, Corning Inc. GLW and TESSCO Technologies Inc. TESS.

Industry: Communications


The Zacks Communication - Components industry appears to be mired in a challenging macroeconomic environment and uncertain business conditions despite a gradual revival in post-pandemic market conditions. In addition, high capital expenditures for infrastructure upgrades, margin erosion, inflationary pressures, supply-chain disruptions driven by the prolonged Russia-Ukraine war and high customer inventory levels have dented the industry’s profitability.


Nevertheless, Arista Networks, Inc., Corning Inc. and TESSCO Technologies Inc. might benefit in the long run as demand for scalable infrastructure rises for seamless connectivity with the wide proliferation of IoT, fiber densification and accelerated 5G rollout.

Industry Description

The Zacks Communication - Components industry primarily comprises companies that provide diverse telecom products and services to develop scalable network architecture, demand-driven video solutions and broadband access equipment. These include various building blocks such as small cells, routers and antennas incorporated into equipment and facilities and subsequently utilized by service providers to build networks for end users.

The product portfolio encompasses optical and copper connectivity products, hybrid fiber-coaxial equipment, edge routers, metro Wi-Fi, storage and distribution equipment for cable TV operators, modems, EMTAs (Embedded Multimedia Terminal Adapter), gateways, set-top boxes, analog and digital microphones, audio processors, glass substrates for LCD TVs and notebooks, ceramic substrates for mobile and laboratory filtration products.

What's Shaping the Future of the Communication Components Industry

Inflated Equipment Prices: The industry is continuously facing a shortage of chips, which are the building blocks for various equipment used by telecom carriers. Uncertainty regarding chip shortage and supply-chain disruptions leading to a dearth of essential fiber materials, shipping delays and shortages of other raw materials are likely to affect the expansion and rollout of new broadband networks.

Extended lead times for basic components are also likely to adversely impact the delivery schedule and escalate production costs. Moreover, high raw material prices due to the prolonged Russia-Ukraine war and the consequent economic sanctions against the Putin regime have affected the operation schedule of various firms. Although various steps have been taken to address the global shortage of semiconductor chips and devise ways to increase domestic production, the demand-supply imbalance has crippled operations and largely affected profitability due to inflated equipment prices.

Fiber Densification: Fiber networks are essential for the growing deployment of small cells that bring the network closer to the user and supplement macro networks to provide extensive coverage. Telecom service providers are increasingly leaning toward fiber optic cable to meet the burgeoning demand for cloud-based business data and video-streaming services by individuals.

Moreover, the fiber-optic cable network is vital for backhaul and last-mile local loop, which are required by wireless service providers to deploy the 5G network. Higher utilization of advanced routers to deliver data packets from one network to another is gaining prominence, while state-of-the-art antenna systems remain essential architectural components for seamless connectivity. Telecom firms are aiding their customers to move away from an economy-of-scale network operating model to demand-driven operations by offering easy programmability and flexible automation.

The industry participants enable customers to manage the exponential bandwidth costs effectively through steady investments in state-of-the-art technologies. These include DOCSIS (Data Over Cable Service Interface Specification), DSL (Digital Subscriber Line) and Next Generation PON (Passive Optical Network) platforms that enable service providers to deliver the highest bandwidth to subscribers across any physical connection.

Margin Woes Persist: The exponential growth of mobile broadband traffic and home Internet solutions has resulted in a massive demand for advanced networking architecture, forcing service providers to spend more on routers and switches as carriers aim to upgrade their networks. Further, there is a continuous need for network tuning and optimization to maintain superior performance standards, creating demand for state-of-the-art wireless products and services.

Although higher infrastructure investments will eventually help minimize service delivery costs to support broadband competition and wireless densification, short-term profitability has largely been compromised. High technological obsolescence of most products has escalated operating costs with steady investments in R&D. In addition, high customer inventory levels and a conservative approach for indenting high-value items remain other headwinds.
