Innodata vs. Nebius: Which Technology Stock Is a Better Buy for 2027?

Investors choosing between Innodata (INOD -2.29%)and Nebius Group (NBIS -9.92%)are weighing two different approaches to the artificial intelligence boom. Both companies target high-growth niches, but which is the better buy today?

Innodata focuses on data engineering and evaluation frameworks, helping giant technology firms refine their large language models. Nebius Group operates as an AI cloud company, providing the essential infrastructure and compute power needed to train and deploy these systems. Comparing them requires looking at how they scale their very different operational models.

The case for Innodata

Innodata provides data engineering and evaluation frameworks to help companies build trusted artificial intelligence systems. It uses a global workforce of over 6,000 professionals to serve some of the largest companies among tech stocks today. Customer concentration like this adds a layer of risk, as one customer in the Digital Data Solutions segment accounted for nearly 58% of revenue in 2025.

In the 12 months ended Sept. 30, 2026, revenue reached nearly $350.2 million, which represents a growth of approximately 46.9% over the prior twelve-month period. Net income for the same period was approximately $48.5 million. This growth trend reflects a significant increase in demand for the specialized human-in-the-loop data services required to train modern generative models.

As of its December 2025 balance sheet, the current ratio is approximately 2.7x, indicating the ability to cover short-term liabilities with short-term assets. Its debt-to-equity ratio is 0.0x, a metric that compares total debt to shareholder equity to assess financial leverage. In the fiscal year ended Dec. 31, 2025, free cash flow was nearly $35.6 million. Note that stock-based compensation accounted for roughly 23.8% of operating cash flow, inflating reported cash generation, as SBC is a non-cash expense added back to cash flow.

The case for Nebius

Nebius Group operates as a full-stack infrastructure provider, supporting the artificial intelligence lifecycle from initial data training to final production deployment. The company serves a diverse range of start-ups and global enterprises across North America, Europe, and the Middle East. It currently employs over 1,300 professionals to manage its data center operations and cloud software offerings.

In the 12 months ended June 30, 2026, revenue reached approximately $1.4 billion, a growth of nearly 460.9% compared to the prior twelve-month period. The company reported a net income of nearly $42.4 million during this period. This rapid expansion in sales highlights the intense global demand for high-performance compute resources and AI-specialized cloud services.

As of the December 2025 balance sheet, Nebius Group carries a debt-to-equity ratio of approximately 1.1x. Its current ratio is roughly 3.1x, providing a healthy cushion for meeting its upcoming financial obligations. In the fiscal year ended Dec. 31, 2025, free cash flow was roughly -$3.7 billion, and stock-based compensation accounted for nearly 21.6% of operating cash flow, indicating that non-cash equity awards significantly affect reported cash generation.

Risk profile comparison

Innodata faces several challenges, starting with its high revenue concentration since a single customer accounted for approximately 58% of revenue in 2025. The company also deals with intense competition from specialized AI data firms and large business process service providers. Additional risks include legal and regulatory hurdles, such as an ongoing securities class action and a legacy labor judgment in the Philippines.

Nebius Group operates in a capital-intensive industry where building and maintaining data center infrastructure requires significant investment. The company faces stiff competition from established cloud giants such as Amazon (AMZN -0.29%)and Microsoft (MSFT +0.17%). These rivals possess vastly greater financial resources and existing customer bases, which could limit the growth of smaller infrastructure providers.

Valuation comparison

Innodata appears to be the more value-oriented choice today, as its valuation multiples sit much lower than those of Nebius Group.

Valuation metrics include those sourced from Financial Modeling Prep (FMP) and may differ from those of other data providers.

Which stock would I buy for 2027?

When comparing Innodata and Nebius, investors should consider a few key factors. Let’s have a look at them and see what that tells us about each stock.

Firstly, we should consider revenue growth. Both companies are growing rapidly. However, Nebius gains an edge in this category, given its 398% revenue growth over the last three years. Innodata’s average revenue growth of 68% is also impressive, but Nebius gains the edge given its truly astonishing growth.

Another factor to consider is each company’s profitability. Here, Innodata has the advantage. Its operating margin of 14.5% indicates that it is turning a decent profit. Nebius, on the other hand, has a current operating margin of -22.3%, showing a lack of consistent profits.

Finally, there’s valuation. We’ll examine price-to-sales (P/S) ratios. Once again, Innodata has an edge. Its P/S ratio of 3.6x is more affordable than Nebius’ 15.1x multiple.

To sum up, both of these tech stocks may appeal to growth-oriented investors. Indeed, those focused squarely on growth will likely prefer Nebius given its incredible growth. However, taking the whole picture into account, Innodata gets the nod in my view, given its better profitability and more reasonable valuation.
