(OTCQB: XERI) ("Xeriant" or the "Company"), a company focused on the discovery, development, and commercialization of transformative technologies, today announced that its NexBoard™ fire-resistant construction panel has achieved a Class A fire rating based on the ASTM E84 certification testing, the highest classification available under the standard. ASTM E84, commonly referred to as the Steiner Tunnel Test, is one of the construction industry's most stringent and widely recognized standards for evaluating the surface burning characteristics of building materials. The test measures flame spread and smoke development, providing critical performance data used by builders, architects, engineers, regulators and insurers. “This is a major accomplishment for NexBoard and an important validation of the years of development behind our technology,” said Brigadier General Blaine Holt, President of Xeriant’s Factor X Research Group. “Not only is this a game changer for the homebuilders we've been working with who are seeking safer, more resilient building materials, but the response has been equally enthusiastic from companies in several other industries.” NexBoard is designed as a next-generation alternative to traditional drywall and other conventional construction panels. In addition to its fire-resistant properties, the product is engineered to provide resistance to water, mold, insects, and environmental degradation, making it well-suited for modern construction methods, including modular and prefabricated building. “This achievement will help unlock our commercialization backlog that have been awaiting third-party certification and validation before advancing toward purchase orders,” stated Keith Duffy, CEO of Xeriant. “The ASTM E84 test is a foundational milestone and one of several building materials tests currently underway as part of a comprehensive certification program.” For additional information about Xeriant and its advanced materials platform, visit <a href="https://www.globenewswire.com/Tracker?data=BPBoia8_0GRCvLsonVeQ6ex_-8QlIy0iH0PX1CIi5ZdnvsAn1IBrGPxUWbJx0-91rCsqxo4LrRKYtRKnjcVvsg==" rel="nofollow" target="_blank" title="">www.xeriant.com</a>.
