Aeva Technologies vs. Cognex: Which Computer Vision Stock Is a Better Buy in 2026?

Computer vision is part of our automated future — and present. Aeva Technologies (NASDAQ:AEVA) and Cognex Corporation (NASDAQ:CGNX) offer different paths into the computer vision market. One is a speculative high-growth play, while the other provides steady returns from established industrial technologies.

Aeva is pioneering next-generation sensing technology, while Cognex dominates the mature field of machine vision. Investors often compare them because both are essential for the expansion of robotics and automation. While their technologies overlap in purpose, their financial stages and risk profiles are worlds apart for your portfolio.

Aeva sells 4D lidar-on-chip systems that combine sensing and processing on a single silicon chip. Its primary markets include automated driving, robotics, and consumer devices. The company is part of the fast-growing tech stocks landscape, targeting automated driving and robotics. Customer concentration like this adds a layer of risk to the business, as the top three customers accounted for 64% of total revenue in 2025, although that reliance is decreasing. In 2024, Aeva’s top two customers accounted for 74% of revenue.

In FY 2025, revenue reached $18.1 million, up from approximately $9.1 million in the previous year. Despite this 99.4% revenue growth, the company reported a net loss of approximately $145.4 million. This indicates that while the business is expanding its top line, it remains far from profitability. This high valuation is reflected in a steep P/S ratio , which compares the stock price to its revenue per share to help value companies that do not yet have consistent profits.

As of its December 2025 balance sheet, the debt-to-equity ratio stands at roughly 7.7x. This metric, which compares total debt to shareholder equity, suggests a high level of leverage relative to its net worth. The current ratio is approximately 4.3x, showing the company has enough short-term assets to cover its immediate liabilities. Free cash flow was negative at nearly $119.7 million, as the company spent more on operations and equipment than it brought in from sales.

Cognex provides machine vision products that allow robots and automated systems to interpret their surroundings. The company serves the automotive, logistics, and electronics industries, which require high-precision automation. Large customers occasionally account for a material portion of revenue, which can affect pricing power and net margins. The loss or significant reduction of orders from these major clients could significantly hurt the company’s financial performance.

In FY 2025, revenue reached approximately $994.4 million, up nearly 8.7% from the prior year. The company is consistently profitable, reporting net income of close to $114.4 million for the period. This resulted in a net margin of 11.5%, which measures the percentage of revenue remaining after all expenses are paid. Investors often look at the Forward P/E, a metric that uses future earnings estimates to determine how expensive a stock is relative to its profit potential.

As of its December 2025 balance sheet, the debt-to-equity ratio is approximately 0.1x. This indicates a very low level of debt relative to shareholders’ equity. The current ratio is close to 3.8x, showing a healthy ability to meet short-term financial obligations. Free cash flow was strong at nearly $236.8 million, providing capital for reinvestment or shareholder returns. This positive cash generation allows the company to fund its own research and development without relying on external debt.
