RTX’s Pratt & Whitney segment has delivered consistent double-digit organic sales growth, with Q2 2026 adjusted sales reaching $8.9 billion, up 17% year-over-year, fueled by a 19-23% surge in commercial aftermarket volumes and higher MRO throughput that reduced GTF engine AOGs. Military engine sustainment, including F135 contracts, and the initial rollout of GTF Advantage engines have further supported the segment, prompting RTX to raise full-year 2026 Pratt guidance to high-single-digit growth and overall company organic sales to 8-9%. Traders are monitoring Q3 results, expected in late October, for confirmation that aftermarket momentum and defense backlog conversion outweigh any commercial OE mix headwinds.
