Reports Record Second Quarter 2026 Financial Results

Executive Commentary

Chief Executive Officer Benjamin Gliklich commented, "Element Solutions delivered a record quarter of revenue, adjusted EBITDA and adjusted EPS. Our strategic execution - marrying operational excellence and prudent capital allocation - continues to generate exceptional profit growth. Core markets remain healthy, and customer engagements continue to accelerate to meet our supply chain's ever-more challenging technical roadmaps. The organic outlook for the year improved over the course of the second quarter as reflected in our increased full year adjusted EBITDA guidance, while progress against strategic priorities, including the Micromax integration and Kuprion scale up, reinforces our confidence in the long-term trajectory for the Company."

Mr. Gliklich continued, "Our proposed transaction with Solstice intends to accelerate value creation by forming a stronger, more differentiated electronics portfolio and unlocking compelling synergies. Element Solutions' market leadership positions and strong, entrepreneurial culture complement Solstice's operational expertise and process discipline. Our combined company is poised to create significant long-term value, leading the market in profitability and cash flow generation with many years runway of double digit earnings growth."
