Yehiel Tal , CollPlant's Chief Executive Officer , commented : " The acquisition of LightSolver marks CollPlant's strategic entry into high - performance computing ( HPC ) and photonics computing markets , alongside our regenerative medicine activities . LightSolver's pioneering LPU technology , recently validated in a peer - reviewed study with Germany's HLRS demonstrating acceleration of fundamental HPC workloads by up to 80,000 times , provides an exciting opportunity to diversify our portfolio and create long - term shareholder value . We are also pleased to welcome LightSolver co - founder Dr. Ruti Ben Shlomi to our Board , bringing deep scientific and entrepreneurial expertise as we advance the technology toward commercialization . " Mr. Tal continued , " Concurrently , we remain committed to our leadership in regenerative medicine . We are actively advancing our proprietary plant - derived rhCollagen platform and continue to dedicate significant resources toward establishing strategic partnerships with leading global players to utilize our technology in medical aesthetics and 3D bioprinting of tissues and organs . " Second Quarter and Recent Highlights • Completed the Acquisition of LightSolver : In September 2026 , CollPlant completed the acquisition of LightSolver , a pioneer in laser - based pure photonic computing . This transaction positions LightSolver to accelerate the commercialization of its Laser Processing Unit ( LPU ) as a new computing layer alongside CPU's and GPU's . • Significant HPC Acceleration Demonstrated : Joint research by LightSolver and the High - Performance Computing Center Stuttgart ( HLRS ) published in the ACM proceedings demonstrated projected time - to - solution acceleration ranging from approximately 40 × to more than 80,000 × compared with state - of - the - art GPU - based algorithms , depending on the benchmark problem and algorithm evaluated . • Board of Directors Appointment : Following the closing of the acquisition , CollPlant appointed Dr. Ruti Ben Shlomi , CEO and Co - Founder of LightSolver , to its Board of Directors to support the group's diversified commercial and technological roadmap . Because the acquisition of LightSolver was signed and completed after June 30 , 2026 , the financial results presented below for the three and six months ended June 30 , 2026 do not include the results of operations of LightSolver . Three and Six Month - Period Ended June 30 , 2026 Financial Results GAAP revenues for the second quarter ended June 30 , 2026 , were $ 108,000 compared to $ 179,000 for the second quarter ended June 30 , 2025. The decrease was primarily attributable to lower sales of rhCollagen - based products . GAAP revenues for the six months ended June 30 , 2026 , were $ 181,000 compared to $ 2.2 million for the six months ended June 30 , 2025. The decrease was primarily attributable to a $ 2.0 million development milestone payment from a former business collaborator recognized as revenue in 2025 , which did not recur in 2026 . GAAP cost of revenues for the three and six months ended June 30 , 2026 , was $ 564,000 and $ 880,000 , respectively , compared to $ 186,000 and $ 374,000 for the three and six months ended June 30 , 2025 , respectively . The increase of approximately $ 378,000 and $ 506,000 for the three and six - month periods , respectively , was mainly attributable to lower utilization of production facilities and inventory write - downs recorded during the period . CollPlant Regenerative GAAP gross loss for the second quarter ended June 30 , 2026 , was $ 456,000 , compared to a gross loss of $ 7,000 in the second quarter ended June 30 , 2025 .
