Ecovyst Inc., a leading integrated and innovative global provider of advanced materials, specialty catalysts, virgin sulfuric acid, and sulfuric acid regeneration services, has announced that it has reached an agreement to acquire the sulfuric acid production assets of Cornerstone Chemical Company, located in Waggaman, Louisiana. The acquisition is expected to expand Ecoservices' capacity to serve regeneration and virgin sulfuric acid customers while also providing enhanced flexibility within the Company’s existing plant network in the Gulf Coast.

Ecovyst plans to fund the acquisition using cash on hand, and the transaction is anticipated to close in the second quarter of 2025, subject to customary closing conditions. This move represents a significant strategic step for the company, strengthening its operational presence in the region while further solidifying its position in the sulfuric acid market.

“The acquisition of Cornerstone’s sulfuric acid assets represents a unique opportunity for Ecoservices to strengthen its network of facilities and expand its ability to support the future growth needs of our customers on a cost-efficient basis,” said George L. Vann, President of Ecoservices. “We look forward to serving the Waggaman plant’s existing customers and strategically incorporating the acquired assets to support the future growth needs of Ecoservices’ customers.”

This acquisition is particularly beneficial due to the Waggaman plant’s close proximity to Ecoservices’ existing operations in Baton Rouge, Louisiana. By adding this facility to its portfolio, Ecoservices aims to enhance operational resilience and improve service capabilities for customers in the region. The Gulf Coast is a key industrial hub, and the addition of the Cornerstone assets will contribute to Ecovyst’s ability to meet increasing demand for sulfuric acid regeneration and production services.

Kurt J. Bitting, Ecovyst’s Chief Executive Officer, emphasized the financial and strategic advantages of the deal. “Given its proximity to our existing Baton Rouge site and alignment with our broader Gulf Coast operations, the acquisition of Cornerstone’s sulfuric acid assets not only complements Ecoservices’ current footprint but is also expected to bolster the resilience of its overall plant network. We are acquiring the assets at a cost below replacement value, aligning with our plan for executing on our high-return organic growth initiatives and targeting strategic bolt-on investments in Ecoservices. Additionally, the assets are being acquired at a transaction multiple basis that is favorable compared to Ecovyst’s current trading multiple, considering the expected pro forma EBITDA post-integration.”

The acquisition underscores Ecovyst’s commitment to investing in high-return opportunities while enhancing its ability to provide critical services to key customers. By expanding its sulfuric acid production and regeneration capacity, Ecovyst continues to reinforce its position as a leading provider of high-performance chemistry solutions. Furthermore, the deal aligns with the company’s overarching strategy of maximizing value creation for shareholders and sustaining long-term growth.

As the closing of the transaction approaches, Ecovyst remains focused on a seamless integration process to ensure continuity of service for customers and optimal utilization of the newly acquired assets. The company’s investment in these assets demonstrates its ongoing dedication to operational efficiency, customer support, and strategic expansion in essential industrial markets.
