Emerson Completes AspenTech Buyout After Portfolio Overhaul
Global – October 31, 2026 -- Emerson completed the acquisition of all outstanding AspenTech common stock it did not already own in March 2025, the latest step in a portfolio reshaping that began with an all-cash $1.6 billion deal in 2020.
Emerson built a 55% AspenTech stake in 2022 before moving to full ownership
In May 2022, Emerson and AspenTech closed the combination of Emerson's industrial software businesses, OSI Inc. and its Geological Simulation Software business, with AspenTech. The deal created what the companies called a global industrial software leader, "new AspenTech." Emerson held 55% on a fully diluted basis, and AspenTech shareholders held the remaining 45%.
In November 2024, Emerson proposed to acquire all remaining AspenTech shares. It also began exploring strategic alternatives, including a cash sale, for its Safety & Productivity segment.
