The case for Arista Networks

Arista Networks provides high-performance networking solutions for companies among tech stocks, specifically focusing on massive data centers. The company has a significant revenue concentration with two end customers, which represented 16% and 26% of total revenue in 2025, respectively. Customer concentration like this adds a layer of risk to the business, as it depends heavily on capital spending from a few major tech firms.

In FY 2025, revenue reached nearly $9.0 billion, which represents a 28.6% increase over the previous year. The company reported net income of approximately $3.5 billion for the same period. This resulted in a net margin of 39%, reflecting the company’s ability to turn a high portion of sales into actual profit.

As of its December 2025 balance sheet, the current ratio is nearly 3.0x, indicating the company has three dollars in assets for every dollar of liabilities due within a year. Arista also holds a debt-to-equity ratio of 0.0x, which means it carries no debt relative to its shareholder equity. It generated nearly $4.3 billion in free cash flow, representing the cash remaining after the business pays for operations and equipment.

The case for AppLovin

AppLovin operates an advertising platform that helps developers grow and monetize their apps using advanced artificial intelligence tools. In June 2025, the company completed the sale of its internal apps business to focus entirely on its software and advertising platform. It serves a global market of advertisers, including mobile gaming firms and consumer brands seeking to optimize their digital spending.

In FY 2025, revenue reached approximately $5.5 billion, marking a significant 70% growth rate compared to the prior fiscal year. This growth helped the company achieve a net income of nearly $3.3 billion and a net margin of 60.8%. These figures highlight the massive scale the company has reached since the launch of its Axon AI engine.

As of the December 2025 balance sheet, the current ratio is nearly 3.3x, suggesting the company maintains a strong buffer to cover short-term obligations. The debt-to-equity ratio of 1.7x indicates that total liabilities exceed shareholder equity. AppLovin generated nearly $3.9 billion in free cash flow, which is the cash left over after supporting its platform operations and infrastructure.

Risk profile comparison

Arista Networks faces significant revenue concentration, as a few cloud titans dictate its financial success through their capital expenditure priorities. The company relies heavily on Broadcom for essential switching chips, creating a supply chain vulnerability. Furthermore, it must compete against Cisco and low-cost hardware providers while keeping pace with rapid technological shifts in AI networking.

AppLovin is highly dependent on third-party mobile platforms like Apple and Alphabet, which can change privacy policies at any time. The company faces intense competition from Meta Platforms, Amazon, and Unity for advertising dollars and data capabilities. Additionally, evolving global privacy laws pose ongoing compliance risks that could impact how the company targets users with ads.

Valuation comparison

AppLovin currently carries a lower Forward P/E and P/S ratio than Arista Networks. These metrics compare the stock price to future earnings estimates and annual sales.

Which stock would I buy in 2026?

I’d go with Arista Networks, and after its most recent quarter, this stock is deserving of your attention. The company just posted its first-ever $3 billion quarter and raised its full-year outlook for the third time this year. Demand for its AI-specific networking products has gone from a trickle to a flood, with the customer count crossing one hundred in under two years. Operating margins are expanding even as revenue grows at a pace that keeps surprising analysts to the upside.

AppLovin’s AI-powered advertising platform is one of the more profitable software businesses being built right now, and the long-term vision of expanding beyond mobile gaming into e-commerce and other verticals is worth taking seriously. But the Q2 revenue miss and below-consensus guidance introduced uncertainty at a moment when the stock was already under significant pressure.

Supply chain headwinds are something Arista is managing carefully, but every major metric is pointing in the right direction. For a long-term investor, Arista’s position at the center of the AI networking build-out, with the results to back it up, makes it the stronger pick right now.
