Future Outlook

Management expects low single-digit revenue growth for fiscal year 2026, with the first half relatively flat year-over-year and volume increasing sequentially in the second half. The revenue outlook contemplates approximately $30 million of accelerated deliveries into Q4 FY25 from FY26. Fiscal year 2026 full-year adjusted EBITDA margin is expected to approach mid-teens, with low double-digit margins in the first half expanding in the second half, and Q4 FY26 margin expected to be the highest of the fiscal year. The company anticipates being free cash flow positive in fiscal year 2026 and is optimistic about achieving its target profile of above-market top-line growth, adjusted EBITDA margins in the low to mid 20% range, and free cash flow conversion of 50% over time.

Management Comments

• "We delivered very strong results in the fourth quarter that were once again in line with or ahead of our expectations, resulting in solid year-over-year growth in backlog, revenue, net income, adjusted EBITDA, and free cash flow for our full fiscal year 2025." Bill Ballhaus, Chairman and CEO.
• Our focus on performance excellence positively impacted our results primarily in two areas: Net adverse EAC change impacts were in line with recent quarters, reflects maturing capabilities in program management, engineering, and operations, and progress in completing development programs.
• Focus on accelerating customer deliveries generated approximately $30 million of revenue and approximately $15 million of adjusted EBITDA planned for FY26.
• We remain focused on the following levers in our efforts to achieve targeted adjusted EBITDA margins in the low to mid 20% range: Backlog margin expansion as we burn down lower margin backlog and replace with new bookings aligned with our target margin profile; ongoing initiatives to simplify, automate, and optimize our operations; and driving organic growth to realize positive operating leverage.
• We are optimistic on achieving our target profile over time of above market top-line growth, adjusted EBITDA margins in the low to mid 20% range, and FCF conversion of 50%.
