CommScope vs. Arista: Which Networking Stock Packs More Power Now?

The article evaluates networking infrastructure firms CommScope (COMM) and Arista Networks (ANET), concluding that CommScope presents a more compelling investment opportunity. CommScope, a Zacks #1 Strong Buy, has seen its stock gain 256.8% over the past year, driven by strategic divestitures, key acquisitions like Casa Systems' Cable Business, and cost-cutting, positioning it for wireline/wireless network convergence. The company projects 4,400% EPS growth for 2025 and trades at a forward P/E of 10.59. Conversely, Arista Networks, a Zacks #2 Buy, leads in high-performance Ethernet switches and benefits from strong enterprise demand and a software-driven approach, but faces headwinds from rising operating costs and supply chain issues, with its shares up 76% and a forward P/E of 46.65.

Analysis

CommScope (COMM) and Arista Networks (ANET) present contrasting investment profiles within the networking infrastructure market. CommScope is executing a significant turnaround strategy, characterized by stringent cost-cutting, the divestiture of its non-core Home Networks business, and the strategic acquisition of Casa Systems' Cable Business to bolster its position in Access Network Solutions. This restructuring is reflected in dramatic forward estimates, with the Zacks Consensus for 2025 pointing to 11.2% sales growth and an extraordinary 4,400% EPS increase, supported by EPS estimates that have risen 46.6% in the past 60 days. Despite its stock price skyrocketing 256.8% over the past year, COMM trades at an attractive forward P/E of 10.59. However, the company faces considerable risks from intense competition, US-China trade tensions, and raw material price volatility. In contrast, Arista Networks is an established leader in high-performance Ethernet switches, benefiting from strong enterprise demand for its software-driven solutions like the EOS and CloudVision stack. ANET projects robust 2025 growth with sales expected to rise 24.6% and EPS by 23.8%. This stability and market leadership come at a premium valuation, with a forward P/E of 46.65. Headwinds for Arista include rising operating expenses, which grew 13.8% year-over-year to $452.4 million in Q2 2025, margin erosion from product redesigns, and supply chain bottlenecks that are tying up working capital in inventory.

Key Decisions for Investors

• Investors may consider CommScope as a high-potential turnaround play, given its exceptionally low forward P/E of 10.59 and a projected 4,400% EPS growth, but should closely monitor the execution of its restructuring and the impact of external competitive and geopolitical risks.
• For Arista Networks, the premium valuation with a forward P/E of 46.65 warrants caution; investors should scrutinize future earnings for evidence of margin stabilization and resolution of supply chain issues, as persistent cost pressures could challenge the stock's current multiple.
• A relative value assessment suggests that investors with a higher risk tolerance seeking growth at a reasonable price may find CommScope's combination of strong price momentum, significant upward estimate revisions, and lower valuation more compelling than Arista's stable but expensive profile.
