This morning, we issued our earnings press release and posted our presentation slides on our website. I will begin the call today with a brief review of the fiscal year, followed by an aerospace product spotlight and some end market commentary supporting our fiscal 2027 outlook. Pat will cover the quarterly financial results as well as the fiscal 2027 outlook. For the last several years, we have used a systematic approach to our growth initiatives, which includes identifying the most attractive opportunities and allocating the resources needed to capitalize on them.
We broadened our growth platforms this year through wins tied to AI-powered data centers, defense programs, mining projects, and next-generation vehicle powertrains. In addition to the growth we saw from our own strategic initiatives, we experienced improvements in several of our end markets. The final component of sales growth is price, driven by higher tungsten costs. Full year organic sales increased 19% year-over-year, driven by additional price realization and modest volume.
From an end market perspective for fiscal 2026, all end markets experienced growth on a constant currency basis. For the full year, adjusted EPS increased to $4.57 compared to $1.34 in the prior year. Adjusted EBITDA margin was 26.9% compared to 15.2% in the prior year. As expected, free cash flow was adversely impacted by increased working capital requirements related to tungsten prices.
