ServiceNow vs. Snowflake: Which Tech Stock Is the Better Buy for 2027?

Should you invest in the operational brain of the modern office or the central engine of its data? We look at ServiceNow (NYSE:NOW) and Snowflake (NYSE:SNOW) to see which is the better buy.

ServiceNow specializes in automating workflows and digitizing business processes, making life easier for employees. Snowflake provides a cloud-native platform for storing, sharing, and analyzing massive amounts of data. Both companies are high-growth leaders in their respective categories, but they follow very different business models and possess distinct financial profiles.

ServiceNow: The workflow engine inside the enterprise

ServiceNow operates an AI platform that connects people and processes by automating manual tasks across departments such as IT, HR, and customer service. The company serves roughly 8,700 enterprise customers, including more than 600 clients that generate over $5 million in annual contract value. It has expanded its reach through strategic alliances with major tech companies.

On a trailing-12-month basis through the September quarter, revenue reached nearly $15.4 billion, representing growth of approximately 22% compared with the prior fiscal year. The company remains consistently profitable, reporting net income of close to $1.4 billion for the period. This resulted in a net margin of roughly 9.4%, demonstrating the ability to generate significant earnings while continuing to invest in its global expansion and AI integration.

As of its September 2026 balance sheet, the debt-to-equity ratio is approximately 0.6x, indicating that its total debt is low relative to its shareholders' equity. The current ratio, which measures the ability to cover short-term bills, is roughly 0.7x.

TTM free cash flow was roughly $4.7 billion, though note that stock-based compensation accounted for roughly 35.9% of operating cash flow, inflating reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

Snowflake: Faster growth, but no profit yet

Snowflake provides the AI Data Cloud, a platform that allows organizations to break down data silos and collaborate across multiple cloud environments. The company has grown its customer base to over 13,328 accounts, including nearly 800 of the Forbes Global 2000. It relies on a deep network of partners, including global systems integrators such as Accenture and Infosys, to help customers implement and scale their data strategies.

TTM revenue through Snowflake's July quarter reached nearly $5.4 billion, a growth rate of approximately 32% year over year. Despite this rapid top-line expansion, the company reported a net loss of close to $1.1 billion over the same period. This resulted in a net margin of roughly -20%, as the business continues to prioritize customer acquisition and product development over immediate GAAP profitability.

As of its July 2026 balance sheet, the debt-to-equity ratio is roughly 1.3x, calculated by dividing total debt by shareholders' equity. Its current ratio is approximately 0.9x, providing a healthy cushion to meet short-term obligations.

TTM free cash flow through July was nearly $1.2 billion, but note that stock-based compensation represented roughly 130.9% of operating cash flow, meaning this non-cash add-back heavily inflates cash generation.

Risk profile comparison

ServiceNow faces intense competition from legacy and AI-native vendors, including Salesforce and Oracle, which may put pressure on pricing. The company also addresses the complexities of integrating AI technology while maintaining high levels of data security.

Furthermore, ServiceNow navigates significant government contracting hurdles and the constant challenge of attracting and retaining highly skilled AI talent in a tight labor market.

Snowflake faces significant competitive pressure from large public cloud providers, such as Alphabet and Microsoft, that both host its platform and offer competing data tools. Its consumption-based revenue model introduces volatility, making it difficult for investors to forecast quarterly results with precision.

Additionally, Snowflake must manage security vulnerabilities and the challenges of scaling professional services while complying with evolving global data privacy and AI-specific legislation.

Valuation comparison

ServiceNow appears significantly more affordable on a price basis, trading at a much lower multiple for both its sales and future earnings estimates.

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?

Both companies have steadily grown revenue at high rates, despite competition in their respective market. However, I would buy ServiceNow for a few reasons.

ServiceNow stock is down over worries that agentic AI tools will reduce demand for its software. But subscription revenue growth has remained fairly steady throughout 2026, and management's guidance calls for 21% year-over-year growth in constant currency for the full year.

It appears to have a successful path to positioning itself as the crucial governance and security layer for agentic AI. Its backlog grew 21% year-over-year last quarter, indicating demand for its offering remains strong.

Snowflake is also remaining resilient despite concerns about competition in its market. But I prefer to buy ServiceNow because of its lower valuation. Snowflake trades at high multiples of earnings and sales, while ServiceNow trades at a more average multiple of forward earnings despite above-average revenue growth and margins. I believe ServiceNow is likely undervalued and can outperform the market, possibly in 2027 and in the coming years.
