Erica McLaughlin, Cabot President and Chief Executive Officer commented: “I am pleased by the strong execution of our teams during a fiscal year that was shaped by a difficult macroeconomic backdrop in many of our key end markets. We finished the year with a strong fourth quarter, delivering Adjusted EPS of $1.61, driven by robust performance in our Performance Chemicals segment. The segment delivered EBIT of $60 million in the quarter and $235 million for the fiscal year. Reinforcement Materials delivered segment EBIT of $87 million in the quarter and $379 million for the full year."

McLaughlin continued, "We also achieved an important milestone in our Battery Materials product line, delivering $43 million of EBITDA for fiscal 2026, a new high for the product line. Building on this momentum, we signed an agreement with the U.S. Department of Energy for a $50 million grant to support our expansion of domestic production of advanced conductive additives for batteries at our facilities in Louisiana and Texas. We expect these investments to strengthen our Battery Materials platform in North America and expand our capabilities to support growing demand for battery energy storage systems, electric vehicles, and other specialty battery applications. As I look ahead, I am excited about Cabot's prospects and our ability to build on our strong foundation in Battery Materials to drive long-term growth and shareholder value."

Fourth Quarter Financial Detail

For the fourth quarter of fiscal 2026, net income attributable to Cabot Corporation was $66 million ($1.25 per common share). Net income reflects an after-tax per share charge from certain items of $0.36, primarily related to charges for restructuring actions. Adjusted EPS for the fourth quarter of fiscal 2026 was $1.61 per share.

Segment Results

Reinforcement Materials – Fourth quarter fiscal 2026 EBIT in Reinforcement Materials decreased by $32 million compared to the fourth quarter of fiscal 2025. The decline in EBIT was primarily driven by lower gross profit per ton, which was partially offset by higher volumes.

Page 2 of 7

Exhibit 99.1

Gross profit per ton declined primarily due to the outcomes of our calendar year 2026 customer agreements and less favorable regional product mix. Volumes increased by 5% in the fourth quarter of fiscal 2026 as compared to the fourth quarter of fiscal 2025 driven by higher volumes in Asia Pacific and the Americas, including higher volumes from our capacity addition in Indonesia and our acquisition in Mexico.

Our results reflect disciplined execution across the organization, particularly in commercial and operational excellence. Performance Chemicals segment EBIT increased 18% year-over-year supported by continued strong momentum in our battery materials product line and higher

volumes in our specialty carbons product line. Reinforcement Materials segment EBIT declined 29% year-over-year, as 3% higher volumes were more than offset by lower gross profit per ton. Overall, I am encouraged by our team’s performance as we navigate dynamic market conditions.”

Keohane continued, “As we continue to optimize our asset footprint, the Company intends to target capacity rationalization at facilities in South America and Europe, subject to local consultation processes. These actions are intended to better align production with demand conditions and enable a more efficient manufacturing network to meet our customer supply needs. We expect these actions will generate annualized fixed cost savings of approximately $22 million once fully implemented.”

Keohane continued, “We continued to generate strong operating cash flow that enabled us to invest in capital expenditures and return cash to shareholders. Our balance sheet remains strong with available liquidity of $1.3 billion and a net debt to EBITDA ratio of 1.5 times as of March 31, 2026. I am pleased with the solid cash flow performance and our strong balance sheet, which enable us to continue to deliver on our capital allocation priorities.”

Segment Results

Reinforcement Materials – Second quarter fiscal 2026 EBIT in Reinforcement Materials decreased by $38 million compared to the second quarter of fiscal 2025.
