(NYSE: BWXT) announced today a contract award from the U.S. Department of Energy's National Nuclear Security Administration (DOE/NNSA) to deliver a conceptual design for the first module of a new Lithium Processing Facility to be constructed at the Y-12 National Security Complex. Lithium reprocessing is an ongoing function currently conducted in aging facilities. NNSA's national security mission requires modernization in order to continue direct reuse, purification, component production and salvage efforts. "This project represents an important investment in modernizing the nation's nuclear security infrastructure and ensuring NNSA has the capabilities needed to support its mission well into the future," said Heatherly Dukes, president of BWXT's Technical Services Group. "Our decades of experience managing and operating complex, high-consequence sites give us unique insight into designing and constructing facilities that are ready to operate." BWXT is teamed with Edgewater Technical Associates, Evans General Contractors, Process Engineering Associates and Merrick & Co. on this project. Acceptance of BWXT's proposal followed a competitive process selecting two companies to advance a multi-phase approach for Lithium Processing Facility construction. In phase one (a four-month, $4 million contract), NNSA will evaluate both companies' conceptual designs for the facility's Machining and Inspection Module. At the second phase of design completion, NNSA then intends to down-select to one company and initiate the third phase of contract negotiations for construction of the module with one single qualified developer team. Additional modules of the Lithium Processing Facility would be designed and built under separate contracts. Forward-Looking Statements BWXT cautions that this release contains forward-looking statements, including statements relating to the performance, timing, impact and value of the contract to deliver a conceptual design for the first module of a new Lithium Processing Facility to be constructed at the Y-12 National Security Complex, and the award or exercise of any contract options or orders. These forward-looking statements involve a number of risks and uncertainties, including, among other things, modification or termination of the contract and delays.

Merrick & Company and Teledyne Optech strengthen strategic partnership to advance geospatial innovation. COLORADO - July 14, 2026 - Merrick & Company is strengthening its longstanding strategic partnership with Teledyne Optech (Teledyne), reinforcing a more than decade-long collaboration focused on advancing geospatial technology, improving data collection capabilities, and delivering greater value to clients. Merrick's latest investment in Teledyne's next-generation airborne mapping technology represents another milestone in a relationship built on innovation, trust, and a shared commitment to continuous improvement. As part of the continued partnership, Merrick recently integrated Teledyne's dual Galaxy Edge+ G2 lidar sensor suite and upgraded aerial imaging capabilities into its geospatial operations. The enhanced platform expands Merrick's ability to support applications such as transmission line mapping, transmission line routing, and large-area elevation mapping programs while strengthening the company's capacity to meet evolving client needs. For more than 15 years, Merrick and Teledyne have worked together to evaluate emerging technologies, test new software and hardware capabilities, and provide real-world operational insight to shape future product development. Merrick's geospatial team has long-served as an early adopter and trusted testing partner to Teledyne, providing feedback that helps refine solutions for the evolving needs of the geospatial industry. Rather than a traditional supplier-customer relationship, the collaboration between the two firms has evolved into a strategic partnership centered on advancing the capabilities of airborne mapping technology and helping clients solve increasingly complex infrastructure and geospatial challenges. "We've always considered Teledyne to be a true partner," said Blaine Horner, Merrick's Geomatics Business Unit Leader. "Their team seeks our feedback, values our operational experience, and works collaboratively with us to improve the technology. That shared commitment to innovation has made this relationship incredibly valuable for both of our companies and, ultimately, for our clients." The new sensor suite allows Merrick to collect data more efficiently while providing flexibility to tailor data acquisition strategies to specific project requirements. By leveraging the expanded capabilities of the new system, Merrick can optimize collection approaches for a wide range of infrastructure and mapping needs while maintaining the high-quality data clients expect. The partnership has also created opportunities for innovation beyond the technology itself. Working closely together, Merrick and Teledyne developed a configuration for the Edge+ G2 suite that allows Merrick to collect nadir and oblique imagery from fixed-wing aircraft - an approach that offers a more efficient and cost-effective alternative to traditional helicopter-based collection methods while maintaining high-quality results. "Teledyne Optech and Merrick have built a strong partnership over the years, with Merrick bringing valuable real-world insight and technical expertise to the table," said Jean-Jacques Dupont, Vice President of Teledyne Optech. "Their willingness to test new capabilities and collaborate on advanced solutions with our teams helps us continue to improve our technology and deliver better outcomes for customers." By combining Merrick's operational expertise with Teledyne's technology leadership, the partnership positions both organizations to respond more effectively to evolving market demands and emerging client needs. It also strengthens continued collaboration on future advancements in geospatial data collection, processing, and analysis. For clients, the benefits extend beyond access to new technology. The partnership provides confidence that Merrick is investing in both the tools and industry relationships necessary to deliver efficient, innovative, and forward-looking geospatial solutions. "This investment reflects more than Merrick's commitment to new technology," said Horner. "It reflects our commitment to building strong relationships with industry leaders who share our passion for innovation. By continuing to strengthen our partnership with Teledyne, we're expanding our capabilities, enhancing the services we provide, and ensuring our clients benefit from the latest advancements in the geospatial industry."
