OneStream's $6.4 Billion Acquisition: A Strategic Leap Towards AI-Driven Financial Solutions

In a significant move to bolster its position in the rapidly evolving landscape of artificial intelligence (AI) in finance, OneStream, a leading financial software developer, is set to go private once more. Private equity firm Hg has announced its acquisition of OneStream in an all-cash deal worth approximately $6.4 billion, translating to $24 per share. This strategic decision is anticipated to catalyze OneStream's AI strategy and innovation in the finance sector.

The Deal and Its Implications

In an exclusive interview, OneStream CEO Tom Shea expressed confidence that the acquisition would accelerate the company's growth trajectory. “We really feel strongly that, in the next 24 to 36 months, the AI world, especially within finance, is going to be defined, and there are going to be emerging winners and losers in that space,” Shea stated. This sentiment underscores the urgency with which OneStream aims to enhance its offerings in AI-powered financial solutions.

Hg's acquisition comes just two years after OneStream's debut on the Nasdaq, where it faced challenges in the public market. The company, under majority ownership of KKR, went public in July 2024 with an initial share price of $20, valuing the company at around $4.6 billion. Despite reporting $568 million in annual recurring revenue in 2024 and a robust growth in AI bookings, which surged by 60% year-over-year in the third quarter, OneStream encountered headwinds due to macroeconomic conditions and questions about the return on investment (ROI) from AI in finance.

Returning to Private Ownership

Shea noted that going private again will enable OneStream to focus on long-term goals rather than short-term quarterly results. “For 90% of our existence, we have been a privately held company, with great partners like KKR. We evolved to being a very viable public company,” he remarked. The decision to go private is seen as a strategic pivot that will allow the company to accelerate its investments in AI without the pressure of public market expectations.

Investment and Strategic Partnerships

Alongside Hg, General Atlantic and Tidemark are joining as minority investors in the transaction, which is expected to close in the first half of 2026, pending regulatory approvals. OneStream boasts a diverse portfolio of over 1,700 customers globally, including major players like Toyota, Capital One, and UPS. The acquisition by Hg, a firm with a long-term investment horizon, positions OneStream to regain control over its growth strategy and investment pace.

Leadership Restructuring for AI Focus

In preparation for this new chapter, OneStream is reshaping its leadership to align with its AI-focused ambitions. John Kinzer, a seasoned board member and former CFO of HubSpot, has stepped in as interim CFO, succeeding Bill Koefoed. The company is actively searching for a permanent finance chief who aligns with its growth trajectory, particularly in AI.

Kinzer emphasized the need for a robust understanding of AI's value creation, which goes beyond reliance on large language models. “Hg recognizes something the public markets have largely overlooked—that AI value creation depends on structured data and domain expertise, not just large language models,” he stated. This perspective highlights the importance of developing platforms that enable customers to realize AI's full potential, leveraging OneStream's strong foundation in financial and operational data.

Strategic Focus on Sustainable Growth

As Kinzer settles into his role, his immediate priority is to position OneStream for sustained expansion. Drawing parallels from his experience at HubSpot, where he successfully led the company through its public offering and subsequent growth, Kinzer is focused on ensuring that investments are strategically aligned with areas promising the highest returns—chiefly, AI.

Shea and Kinzer are working closely during this transitional phase, emphasizing the importance of shared strategic goals. Shea is on the lookout for a CFO who can help scale the company to $1 billion in revenue and beyond, ensuring alignment with the company’s long-term vision.

Commitment to Long-Term Vision

Despite the significant corporate shift represented by the buyout, Shea reassured stakeholders that OneStream's mission and independence remain intact. “There’s no deviation in our long-term vision,” he affirmed. “Shared value creation will continue to guide everything we do—for our investors, employees, and customers.” This commitment to long-term objectives is crucial as the company navigates the complexities of the evolving AI landscape.

Conclusion

The acquisition of OneStream by Hg represents a pivotal moment for the company as it seeks to enhance its AI strategy in finance. By returning to private ownership, OneStream aims to focus on long-term innovation and growth, positioning itself as a leader in AI-driven financial solutions. As the company embarks on this new chapter, stakeholders can expect a renewed commitment to leveraging AI's potential to transform financial operations.

As OneStream navigates this transition, the emphasis on structured data and domain expertise will be vital in realizing the full benefits of AI in finance. The future looks promising for OneStream as it strives to redefine the financial software landscape in the coming years.
