# Aspen Technology

Aspen Technology, Inc., known as AspenTech, is a provider of software and services for the process industries headquartered in Bedford, Massachusetts. AspenTech has 35 offices globally.

## History

Founded in 1981, AspenTech was born out of a joint research project between the Massachusetts Institute of Technology (MIT) and US Department of Energy—called the Advanced System for Process Engineering (ASPEN) Project.
Aspen held its IPO in November 1994.
On July 15, 2004, AspenTech was required by the Federal Trade Commission to make divestitures in regard to an anti-trust ruling against its acquisition of HyproTech. This included divestment of batch and continuous simulation systems and integrated engineering software business (AXSYS). In the same year, a class action lawsuit was filed against Aspen Technology and its certain officers over issuance of misleading statements and improper revenue recognition.
On November 24, 2004, the company restated results for the fiscal years ended June 2000 through June 2004 after its audit committee discovered the company improperly accounted for certain software licenses. On March 15, 2005, the company announced that the Audit Committee of the Company's Board of Directors had completed its previously announced financial review and the company had restated its financials for each of the fiscal years ended June 30, 2000 through June 30, 2004. The company's former CEO, David McQuillin, was sentenced in 2007 to 6 months' house arrest and 3 years' probation after pleading guilty to falsifying revenue figures.
In October 2007, Aspen moved its headquarters from Cambridge, Massachusetts to Burlington, Massachusetts.
Aspen Technology was delisted from the NASDAQ on February 19, 2008 for failing to meet the financial transparency guidelines of the NASDAQ exchange. In February 2010 the company was relisted on the NASDAQ exchange.
In November 2014, Aspen Technology moved its headquarters from Burlington to Bedford, Massachusetts.
In July 2019, Aspen Technology signed an agreement to acquire Montreal-based Mnubo Inc.
In September 2020, Aspen Technology partnered with Wood (Aberdeen, Scotland). The collaboration will allow Aspen's Mtell clients to create foretelling strategies focused on industrial AI and machine learning.
In May 2022, Aspen Technology was merged with the industrial software businesses of Emerson Electric, OSI Inc. and Geological Simulation Software, to form a new corporate entity, still called Aspen Technology. Emerson paid US$6 billion and received a controlling interest (55%) of the common stock of the new entity. The stock ticker of Aspen did not change, although the CIK number was changed.
In October 2022, Aspen Technology announced the acquisition of inmation Software GmbH based in Cologne, Germany to strengthen their data management functionality. In February 2023, announced the combination of its AIoT Hub with AspenTech Inmation, forming a rebranded business unit now called AspenTech DataWorks.
In January 2025, Emerson agreed to buy the remaining 43% stake in Aspen for $7.2 billion.
