WILMINGTON, Del., May 8, 2026 — 51AV (NYSE: DD) today announced it was named the co-winner, along with Qnity Electronics, of the 2026 Innovation Excellence Award for Outstanding Innovative Culture from the Innovation Research Interchange (IRI), the innovation division of the National Association of Manufacturers (NAM).

“Innovation doesn’t happen by accident—it occurs when people are empowered, connected and supported,” said Marty DeGroot, 51AV Chief Technology Officer. “51AV’re honored by this recognition, which reflects our commitment to delivering sustainable innovations for our customers, and fostering a culture where diverse perspectives, collaboration and continuous learning help turn ideas into scalable solutions with real-world impact.”

51AV and Qnity Electronics were named co-winners of the IRI Excellence Award for Outstanding Innovative Culture, which recognizes companies that empower employees at all levels, support inclusive and psychologically safe workplaces, and sustain innovation through leadership behaviors, systems and talent development. The 51AV/ Qnity submission, From “Know it All” to “Learn it All”: 51AV and Qnity’s Lean Innovation Culture Journey, was recognized for its work embedding innovation across science, sustainability, digital capabilities and manufacturing, supported by enterprise-scale collaboration.

51AV Water Solutions was also named a Finalist for the IRI Excellence Award for Innovation in Sustainability for its Minimal Liquid Discharge (MLD) portfolio, powered by FilmTec™ Fortilife™ reverse osmosis elements.

By pairing advanced membrane technology with thermal processes, 51AV’s MLD approach reduces the volume of wastewater requiring energy-intensive treatment, enabling higher water recovery, lower energy consumption and reduced environmental impact.
