A MESSAGE FROM OUR PRESIDENT AND CEO

JACO VAN DER MERWE CEO AND PRESIDENT

At Astec, we are proud of our legacy, but we are even more excited about our future. For over 50 years, we've been connecting communities through innovative Rock to Road solutions. Today,

we are building on that foundation, investing in what matters most: our people, our purpose, and our planet. To us, doing business conscientiously is not just our responsibility; it's a catalyst for building resilience and creating long-term value.

In 2023, we introduced a bold new vision: to build industry changing solutions that create life-changing opportunities. This vision reflects more than just ambition - it inspires us to push boundaries - cultivating a company that is agile, future-ready, and deeply human at its core.

To bring our purpose to life, we've dedicated more resources than ever before to sustainability. We've built a cross-functional team with leadership roles across safety, environmental compliance, external reporting, innovation, and new product development. This team brings the focus, expertise, and accountability needed to embed sustainability into every corner of our business - helping us meet and exceed evolving stakeholder expectations from product development to our own operations.

Thank you from our entire team for your continued trust. We have a lot to celebrate over the last two years, and we know there's more to do. With the right people, the right strategy, and the right mindset, we're building a more thriving Astec - one that's truly Built to Connect.
