ESG Report

From Our President & CEO

2022/2023

ESG Report

When I joined AspenTech in 1993, our customers faced a wide range of challenges, from how to maximize their output and meet quality standards to increasing efficiencies and driving operational performance.

Today, asset-intensive industries face a Dual Challenge - how to meet the increasing demand for resources from a growing population while also addressing sustainability goals. As a strategic partner and an industry steward, we are trusted by our customers to guide them as they take on this challenge.

With more than 40 years of innovation and deep domain knowledge, we enable asset-intensive industries to advance a wide array of sustainability pathways, from converting oil refineries into biofuel-producing assets to scaling and optimizing hydrogen production to the recycling of plastics.

Over the past year, AspenTech has undergone a transformation that has significantly enhanced our ability to impact the energy transition and sustainability. Our customers recognize how uniquely positioned we are to help them achieve this.

Our transaction with Emerson, which closed in May 2022, added two new solutions to the AspenTech portfolio. OSI Digital Grid Management extends our capabilities into electricity transmission and distribution, while Subsurface Science & Engineering enhances our solutions for carbon storage and geothermal energy. Through our partnership, we are also combining AspenTech's innovative software with Emerson's industry-leading automation portfolio to create joint sustainability solutions for emissions management, energy efficiency, bio-feedstocks, hydrogen, and carbon capture, utilization and storage (CCUS).

With the support of Emerson, we have accelerated our ability to acquire new offerings. Inmation, a leader in industrial real- time information management software, enables customers to generate insights that improve operations and drive their sustainability programs. We also announced an agreement to acquire Micromine, a global leader in design and operational solutions for the mining industry.

To accelerate the development of our long-term sustainability vision and align our product plans with this vision, we recently hired a Chief Product and Sustainability Officer.

FROM OUR PRESIDENT & CEO

AspenTech is also evaluating pathways to achieve net-zero emissions across our own operations. We are developing an environmental sustainability program to reduce our carbon footprint, informed by an assessment of our global emissions.

Environmental sustainability is only part of the picture. AspenTech is also committed to helping our global organization thrive by embracing diversity, equity and inclusion and providing continuous development opportunities for current and future generations of the workforce.

Diversity and inclusion have always been important to me. I was born and raised in Latin America and my heritage is a critical part of who I am. I have always believed that the diversity of AspenTech employees is among our greatest strengths and as our workforce has grown significantly in the past year, we have placed even more emphasis on our corporate value around Diversity, Equity and Inclusion (DEI). We have also made strides in the representation of women and the ethnic / racial diversity of both AspenTech's executive team and the Board of Directors.

Because we recognize that our employees are critical to everything we do, we invest significantly in our own culture of operational and organizational excellence, in training and educational programs and in developing the next generation of leaders.

We understand that our work on diversity, equity and inclusion can never be complete. I - and AspenTech as a whole - am dedicated to continuing our efforts, because we know we

are stronger and more successful when we celebrate and appreciate the unique qualities of each employee.

I am honored to serve alongside a talented, experienced and passionate Board of Directors who oversee and support AspenTech's Environmental, Social and Governance (ESG) initiatives, which are a key part of our strategy. More than three

quarters of the Board members are independent, including the Board Chair. Following the close of the Emerson transaction, we took steps to further strengthen our corporate governance including adopting a code of business conduct and ethics for directors, officers and employees and establishing new charters for our committees.

As a software company, we recognize the importance of cybersecurity. Through rigorous processes, advanced tools and continuous employee training, we aim to deliver secure products and help protect our customers so they can securely operate critical infrastructure, like the electrical grid, oil and bio refineries and chemical plants.

It's been an exciting year at AspenTech, one in which we transformed our capabilities to address the Dual Challenge and made significant progress in our ESG initiatives. It

is important for me to recognize that our employees, customers and partners deserve a large measure of the credit. With their talents, passion and innovative spirit, I look forward to continuing

our leadership role in achieving a more sustainable future.
