ESCO Technologies Inc.

What they do

ESCO operates through three segments: Aerospace & Defense (A&D), Utility Solutions Group (USG), and RF Test & Measurement (Test). A&D designs and manufactures filtration products, electro-explosive devices, precision components, and signature and power management solutions for naval and aerospace customers. USG provides diagnostic testing solutions for electric power grid operators and renewable energy decision support tools. Test (ETS-Lindgren) makes products that identify, measure, and control magnetic and electromagnetic energy.

Revenue drivers

• Aerospace & Defense (A&D) — Largest segment; Q3 2026 sales of $168.2M, up 23% y/y, driven by navy and aerospace orders; includes Maritime (acquired April 2025) contributing $22.7M in the quarter.
• Utility Solutions Group (USG) — Q3 2026 sales of $100.0M, up 8% y/y; growth led by Doble (protection testing, offline test equipment, services) offset by NRG weakness in renewables.
• RF Test & Measurement (Test) — Q3 2026 sales of $70.9M, up 5% y/y, driven by U.S. and European operations, partially offset by Asian decline.

Recent performance

In Q3 FY2026 (ended June 30, 2026), sales rose 14% to $339.0M, GAAP EPS from continuing ops increased 31% to $1.26, and Adjusted EPS increased 38% to $2.20. For the first nine months of FY2026, sales were $938.0M and net earnings were $95.0M, compared to $742.7M and $71.4M in the prior-year period. Backlog reached a record $1,540.5M at June 30, 2026, up from $1,133.6M at September 30, 2025.

Strategy

ESCO focuses on organic growth, performance improvement through the 'ESCO Operating System' initiative, and strategic acquisitions. In April 2025, it acquired the Signature Management & Power (Maritime) business, expanding naval offerings. Management emphasizes margin expansion, pricing discipline, and cost control. The divestiture of VACCO in July 2025 (exit from Space) generated ~$270M in net proceeds, used to pay down debt.

Risks

• U.S. Government spending and appropriations — Approximately 23% of FY2025 revenues came from U.S. Government sales – defense spending cuts, shutdowns, or priority changes could impact A&D revenues.
• A&D program concentration — Significant reliance on major U.S. Navy programs (e.g., Virginia Class, Columbia Class); delays or reductions in these programs could hurt results.
• Renewables market weakness at NRG — USG results pressured by lower solar and wind product shipments due to market weakness and expiration of U.S. renewables tax credits.
• Maritime acquisition integration — Acquired backlog of $364.2M will not repeat; integration and performance of Maritime must sustain growth to justify the acquisition.

Outlook

Management raised full-year FY2026 guidance, citing double-digit organic growth across aerospace, Navy, Test, and Doble businesses. Record backlog of $1.54B at June 30, 2026 supports confidence in continued above-market growth. The company expects broad-based demand in utility and defense end markets, with NRG remaining a soft spot.
