Exhibit 99.1

Agreement Between AspenTech and Emerson
Today, AspenTech and Emerson jointly announced an agreement under which Emerson will acquire all outstanding shares of common stock of AspenTech not already owned by Emerson. Upon the closing of the transaction, AspenTech will become a wholly owned subsidiary of Emerson. The press release detailing this news can be found here.
This agreement was reached following a unanimous recommendation from the Special Committee of AspenTech’s board, which conducted a diligent and independent process to evaluate Emerson’s proposal from November 2024. This included extensive discussions with Emerson and listening to feedback from our minority shareholders.
I am excited about this progression in our relationship with Emerson and believe this will position AspenTech as an even stronger partner for our customers as well as an employer of choice for top talent. This is a significant milestone in bringing our two companies together. Emerson understands our business and the criticality of AspenTech’s proven software and recognizes the value of our unmatched domain expertise and continuous innovation, all of which have successfully positioned AspenTech as an industrial software leader. We want to thank you all for your contributions and dedication in getting us here.
This agreement is subject to a non-waivable condition that requires at least a majority of the AspenTech common stock held by minority stockholders be tendered and not withdrawn. Until the transaction is completed, which we expect will occur in the first half of calendar year 2025, we will remain separate companies and it will be business as usual.
Our Q2 All Employee call will be held on February 6 and we will review our Q2 results and focus for the second half of FY25. I am limited in what I am able to communicate regarding the AspenTech and Emerson agreement but will provide as much information as possible, as the process moves forward.
It is likely that our customers and partners will have questions related to this announcement. As was advised in November, it is important to reassure our customers and partners that we remain committed to our continued relationships and the execution of our innovation and strategic priorities. In this regard, on Tuesday January 28, we will issue letters to customers and partners updating them on the announcement. Separately, if you receive any media inquiries, please pass their information on to Aimee Rhone in Corporate Communications.
Thank you for your hard work and continued commitment to AspenTech. The driving force behind our success has always been the passion and dedication of our people and what we have created together over the past 40+ years. It is the exceptional work by everyone across the company that makes AspenTech the industrial software leader it is today.
Let’s stay focused on executing in the second half of FY25 and continuing to deliver value to our customers.
