For purposes of this policy, Inside Information includes any material, non-public information about the Company. All information you learn about the Company or its business plans is potentially nonpublic information until we publicly disclose it. Pre-Trading Clearance: Except in accordance with Section 12, the following procedure will be followed to ensure compliance with this policy.

These methods include: PULTRUSION • Fibers are impregnated with liquid thermoset resins, then pulled through a heated die to cure the resin and form the product • This continuous, automated manufacturing process creates constant cross section profiles of any pre-determined length with consistent, uniform quality and exceptional mechanical performance • Applications include rods and profiles of various lengths and complexities, such as utility poles, insulator core rods and structural beams CONTINUOUS FILAMENT WINDING • Combines the principles of filament winding with pultrusion to create constant or tapered cross- sectional tubing in precision sizes • The unique axial and biaxial fiber orientation provides flexural and tensile strength, as well as crush and burst resistance • Applications include lightweight shelter frames and sporting goods components CONTINUOUS RESIN TRANSFER MOLDING (CRTM™) • Engineered core materials are sandwiched between structural composite laminate face sheets • Continuous composite sandwich panels feature high specific strength and stiffness-to-weight ratio • Applications include ballistic resistant panels, truck floors and rail car doors CONTINUOUS FIBER REINFORCED THERMOPLASTICS • Fully recyclable tape, X-Ply™ (0°/90°), and other multi-ply configurations with widths up to 10' wide • Sandwich panels in unlimited lengths, up to 6" thick and 10' wide • High volume production capacity • Applications include structural and aerodynamic components in transportation, and reinforcement of materials such as wood and metal THERMOSET COMPOSITE LAMINATES & BARSTOCK • Unidirectionally reinforced barstock, laminates and hybrid composites engineered to maximize deflection and fatigue resistance • Customizable shapes and sizes • Applications include archery bow limbs, flat springs, prosthetics, sporting equipment THERMOSET FINISHING OPERATIONS • Customized finishing capabilities for barstock and laminates including machining, water-jet cutting, profiling/shaping, sanding, slitting, laminating, molding and coatings TESTING CAPABILITIES • Mechanical – Flexural, tensile, compression, shear, fatigue, impact resistance • Physical – Specific gravity/density, Barcol hardness, water absorption, void content, resin/fiber content, dye penetrant, viscosity • Thermomechanical – Coefficient of linear thermal expansion, glass transition temperature, deflection temperature, degree of cure, curing properties • Electrical – High-voltage, low current dry arc resistance of solid electrical insulation, dielectric strength, water diffusion ABOUT AVIENT ADVANCED COMPOSITES The Avient advanced composites portfolio consists of Glasforms™, Gordon Composites™ and Polystrand™ branded materials.
