The calculation period is scheduled from February 27, 2026, to May 21, 2026, but can be subject to earlier termination or acceleration. Wells Fargo has the discretion to accelerate the valuation date for all or part of the transaction starting April 9, 2026. The $100,000,000 prepayment was funded using borrowings under Trex's existing line of credit. The ASR program is intended to comply with Rule 10b5-1(c) and repurchases will be effected in accordance with Rule 10b-18.
