Select Water Solutions Reveals Definitive Agreement with ISE Chemicals Corporation Providing for the Development of Commercial Iodine Production Facilities Utilizing Produced Water Infrastructure Across Texas, New Mexico and Oklahoma; Initial Commercial Iodine Facility Expected To Be Commissioned In 2027 In Permian Basin

Select Water Solutions, Inc. ("Select", NYSE and NYSE Texas: WTTR) announced today that subsidiaries of Select and ISE Chemicals Corporation ("ISE Chemicals") (TSE: 4107) have entered into a definitive agreement providing for the development of commercial-scale iodine extraction and refining facilities utilizing produced water sourced through Select's Water Infrastructure network across Texas, New Mexico and Oklahoma.

Under the agreement, ISE Chemicals would fund, design, construct, own, and operate iodine extraction and refining facilities, while Select would provide produced water sourcing, transportation, storage, pretreatment, recycling, and infrastructure support through its existing Water Infrastructure platform, for which Select will receive a royalty payment. The formal collaboration is intended to establish a new U.S. domestic source of iodine while creating an additional value stream from produced water managed across Select's comprehensive network.

The initial commercial facility is expected to be commissioned in 2027 and will be located within Select's core Permian Basin footprint. The facility represents the first phase of a broader development program designed to evaluate scalable expansion opportunities across Select's extensive produced water infrastructure network, with ~3,000 tonnes per year of iodine production targeted by the end of 2030.
