Bull points
- Despite these military margin impacts, earnings growth remains strong, reflecting our exceptional growth trajectory.
- Driven by the strong top line performance, long gap adjusted EBITDA increased 44% from the prior year period to $78 million.
- Diluted earnings per share in the first quarter of 2026 were $0.48, representing an increase of 37% from the first quarter of 2025.
Bear points
- Gross margin was impacted by an increased amount of outsourced components to drive growth and share gains.
- Overhead expenses associated with the Memphis facility impacted segment margin by $9.8 million. Excluding these costs, Oklahoma margins were 29.6 percent. The remaining gap to our historical highs in the upper 30s is explained by three items, outsourcing, tariff-related pressures, and general inflation.
