10 Years of Impact: Introducing the AdvanSix 2025 Sustainability Report

In 2026, AdvanSix marks its 10-year anniversary as an independent company, providing an opportunity to celebrate our progress and reaffirm our commitment to a resilient future. President and CEO Erin Kane reflects on our progress not only in 2025, but over the last decade:

As we approach our 10-year anniversary as AdvanSix, I am reflecting on the power of good chemistry and the lasting impact delivered to help foster a more sustainable, resilient future.

As a vertically integrated chemistry company serving diverse end markets, we play a vital role in global supply chains by delivering essential chemistries. In recognition of that, I'm proud to share our 2025 Sustainability Report.

This year, we reflect on nearly a decade of progress and the important investments we've made throughout our history that reinforce our commitment to environmental stewardship, community engagement and operational excellence.

Some key highlights that show our values in action:

• AdvanSix was recognized with a Gold rating by EcoVadis, an independent corporate social responsibility assessment agency, placing us in the top three percent of all companies assessed.
• We were honored to earn an A- score from CDP (formerly the Carbon Disclosure Project) in water stewardship, representing Leadership-level environmental transparency and performance.
• We were honored to earn an A- score from CDP (formerly the Carbon Disclosure Project) in water stewardship, representing Leadership-level environmental transparency and performance.
• We continued to advance our Sustainable U.S. Sulfate to Accelerate Increased Nutrition (SUSTAIN) initiative to help increase the domestic availability of fertilizer and nutrient alternatives for U.S. farmers.
• We completed a renovation of the dock at our Frankford site as part of continued investment in maintaining safe, stable and sustainable operations and enhancing the resilience of Philadelphia's waterfront.
• We have made significant capital investments since 2018 to improve AdvanSix's emissions and energy footprint. To put that in perspective, our annual carbon dioxide (CO2) emissions have been reduced by more than 300,000 tons, representing a decrease of more than 58%, our company-wide GHG emissions have been reduced by 13% and energy consumption has been reduced by 20%.

A Decade of Progress. A Future of Possibility.

Our commitment to our teammates and the communities in which we operate remains at the forefront of our progress. We continue to give back to our hometown communities and support initiatives that help create opportunities and build resilience for years to come.

As we look ahead, we remain focused on building on our progress, strengthening our community partnerships and delivering long-term value for all stakeholders. Thank you for your continued trust and partnership as we build a more sustainable tomorrow-together.

Sincerely,

Erin Kane
President and CEO
