Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 7.9% to $983.6 million, driven by growth in modules and sub-assemblies ($43.5M increase), components ($15.1M), and integrated solutions ($13.0M). Key growth areas included Land, Naval, and Space platforms, partially offset by a decrease in Airborne platform revenue.
• Margin Expansion: Gross margin improved by 70 basis points to 28.6%, primarily due to lower manufacturing variances and favorable changes in estimates at completion (EAC) on over-time programs.
• Profitability: The company narrowed its GAAP net loss by $8.2 million year-over-year. Adjusted EBITDA grew 25.8% to $150.2 million, reflecting operational improvements and cost management.
• Debt Reduction: The company repaid $150.0 million on its revolving credit facility during the period, reducing outstanding borrowings from $591.5 million to $441.5 million.
• Restructuring: Restructuring charges decreased to $5.9 million (vs. $7.2 million in FY2025), associated with workforce reductions of approximately 100 positions.

Guidance, Outlook, and Risks

Management Commentary: Management highlighted strong demand reflected in a record backlog of $1.9 billion. The company is executing a strategy focused on performance excellence, margin expansion, and cash release. They have begun applying AI and automation to internal operations to improve efficiency.

Outlook: The company anticipates continued growth driven by geopolitical tensions, prime contractor outsourcing trends, and increasing electronics content in defense platforms. They expect to continue reducing debt depending on market conditions and cash flows.

Risks and Contingencies:

• Legal Proceedings: The company settled a securities class action lawsuit for $32.5 million (funded by D&O insurance). A separate lawsuit by Starboard Value LP remains pending. Additionally, an internal investigation regarding potentially inaccurately reported test results for a government program is ongoing, though the customer has stated there is no impact to system performance.
• Supply Chain: Risks include reliance on sole-source suppliers for critical components (FPGAs, ASICs) and potential disruptions from trade policies or tariffs.
• Government Funding: Approximately 97% of revenue is derived from defense programs subject to Congressional appropriations and potential termination.
• AI Risks: The company notes risks associated with the use of third-party AI tools in internal operations and the integration of AI capabilities into customer hardware, including cybersecurity and regulatory compliance.

Investor Verification Checklist

• Backlog Conversion: Verify the rate at which the $1.9 billion backlog is being converted to revenue, given the significant increase from the prior year.
• Legal Exposure: Monitor the status of the Starboard Value LP litigation and the outcome of the internal investigation regarding product test results.
• Debt Covenants: Confirm continued compliance with the Revolver's financial covenants, specifically the minimum consolidated EBITDA and leverage ratios.
• Customer Concentration: Review the stability of the top three customers (RTX, Lockheed Martin, Northrop Grumman), which collectively accounted for 36% of FY2026 revenue.
• Inventory Levels: Assess inventory valuation risks, as inventory balances increased to $367.0 million, requiring ongoing evaluation for obsolescence.
