Slater portfolio company Arctura says ALP20 wind turbine coating shows zero confirmed new lightning damage in field test

• Slater Technology Fund portfolio company Arctura reported field results for its ALP20 lightning-protection coating on operating wind turbines.
• During the 2025-2026 lightning season, 15 ALP20-coated turbines absorbed 35 lightning flashes with zero confirmed new blade damage.
• At the same wind farm, 91 untreated turbines took 198 flashes; 13 turbines showed new repair-level damage, or 6.6 findings per 100 flashes.
• Average exposure was similar: 2.33 flashes per coated turbine versus 2.18 for untreated turbines, suggesting no reduction in strike frequency.
• U.S. lightning-related blade repairs were estimated above USD 255 million in 2025; Arctura plans another monitored season to strengthen evidence.
