FST Corp. Launches KBS TOUR V-X Steel Iron Shaft Family, Engineered for Best-in-Category Stability and Dispersion

Boulder, Colorado--(Newsfile Corp. - September 24, 2026) - FST Corp. (NASDAQ: KBSX) ("FST" or the "Company"), a leading manufacturer and marketer of steel and graphite golf shafts and a provider of other golf-related services, today announced the launch of the KBS TOUR V-X family of steel iron shafts, comprising the KBS TOUR V-X and KBS TOUR V-X Lite.

The V-X family represents the Company's newest steel iron shaft platform, engineered to maximize the strength-to-weight ratio while maintaining the signature KBS feel. Its proprietary flex profile and geometric design allow KBS to deliver greater stiffness and stability at a given shaft weight, providing more precise control of shaft deflection through impact. In Company testing, the family achieved a strength-to-weight ratio up to approximately 20% higher than many of the Company's existing steel iron shafts.
