Arista Networks vs. ServiceNow: Which Technology Stock Is a Better Buy for 2027?
Arista's near-zero debt and 39% net margin stand in sharp contrast to ServiceNow's cheaper valuation, and the gap between them may decide which stock deserves your capital.
Arista Networks and ServiceNow are two technology stocks that investors may consider for growth potential in 2027. Arista Networks specializes in high-performance networking platforms and software for data centers and artificial intelligence environments. In 2025, the company reported $9.0 billion in revenue, a 28.6% increase from the previous year, with a net margin of 39%.
It has low debt and strong liquidity, making it an attractive option for investors seeking profitability. However, Arista Networks faces risks from customer concentration, dependence on critical silicon components, and geopolitical threats.
On the other hand, ServiceNow offers a cloud-based platform for automating complex business tasks. The company generated $13.3 billion in revenue in 2025, with a net margin of 13.2%. It has a conservative debt-to-equity ratio and strong liquidity, but faces competition from established software leaders and cybersecurity risks. ServiceNow's shares have experienced volatility in 2026 due to concerns about generative AI replacing SaaS businesses, but management sees an opportunity to leverage its core IT strength with new GenAI tools.
Comparing the two, Arista Networks appears to have stronger revenue growth and profitability, while ServiceNow offers a more conservative valuation with lower forward P/E and P/S ratios. Ultimately, the better pick depends on an investor's risk tolerance and investment goals.
