OneStream (OS) announced a strategic alliance with Microsoft during Microsoft Ignite 2025. This partnership brings its SensibleAI Agent technology to Microsoft 365 and Azure. The collaboration is designed to accelerate AI adoption in enterprise finance.

After announcing this deepened partnership with Microsoft, OneStream’s stock has shown signs of renewed interest, notching a strong 14.6% share price return over the past month as excitement builds around its expanded role in enterprise AI. Despite this recent upside, momentum has yet to offset the longer-term dip. The one-year total shareholder return is -30.3%, reflecting a market still calibrating the company’s future potential as it forges new tech alliances.

With the recent surge in share price but lingering long-term losses, the key question for investors is whether OneStream remains undervalued given its fresh Microsoft alliance, or if the market has already accounted for its future growth prospects.

Most Popular Narrative: 26% Undervalued

With OneStream's current price significantly below the narrative’s $28.26 fair value estimate, investors are watching to see whether momentum can sustain a long-term turnaround. The narrative’s discount rate of 8.40% provides a framework for ambitious assumptions on growth and profitability.

“Ongoing large-scale digital transformation across industries, with CFOs increasingly seeking unified platforms to replace legacy financial systems, strongly positions OneStream to capture expanding market share, supporting sustained subscription revenue and new customer growth.”

However, ongoing public sector uncertainty and slower SaaS migration could weigh on revenue growth. This may present challenges to the optimistic outlook surrounding OneStream’s future performance.

Another View: What Does the Sales Multiple Say?

Looking through another lens, OneStream is trading at a price-to-sales ratio of 6.9x. This is higher than the US Software industry average of 4.7x, but still below the peer group, which sits at 8.2x. The fair ratio, where the market might eventually settle, is 6.3x. Is this a sign of upside, or does it hint at valuation risk that could keep shares grounded?
