Q2 2026 earnings summary7 Aug, 2026

Executive summary

  • Achieved record first-half 2026 revenue of $28.2 million, up 10% year-over-year, driven by ramp-up of three major Navy prime contracts and a robust backlog anchored in AI-enabled cyber, electronic warfare, and C5ISR programs.

  • Maintained a debt-free balance sheet with $16.9 million in cash at June 30, 2026, supporting organic and M&A growth strategies.

  • Net loss for the first half was $1.4 million, with adjusted EBITDA compressed due to planned growth investments.

  • Seven acquisitions since 2019 have expanded capabilities and market reach.

  • Expects full-year 2026 to set a new revenue record, with multi-year revenue visibility supported by a robust backlog and qualified pipeline.

Financial highlights

  • First half 2026 revenue grew 10% year-over-year to $28.2 million; Q2 revenue was $13.9 million, nearly flat year-over-year.

  • Gross profit for the first half was $9.8 million (34.7% margin), up 2% year-over-year; Q2 gross profit was $4.7 million (34% margin), down from $5.1 million (36%) in Q2 2025.

  • Net loss for Q2 2026 was $1.05 million; first half net loss was $1.4 million, improved from $1.55 million in 2025.

  • Adjusted EBITDA for the first half was $0.4 million (1.4% margin), down from $0.6 million in 2025, reflecting front-loaded investments.

  • Cash and equivalents at June 30, 2026, totaled $16.9 million, up from $14.8 million at the end of H1 2025; operating cash flow for the first half was $2.4 million.

Outlook and guidance

  • Expects record full-year 2026 revenue, with focus on converting backlog and pipeline into higher-margin growth.

  • Plans to recognize approximately 16% of backlog over the next 12 months and 48% over the next 24 months.

  • Continued disciplined execution and investment in business development, M&A, and mission technologies to drive multi-year growth.

  • No immediate plans for share buybacks; capital will be prioritized for organic growth and acquisitions.

  • Management expects sufficient liquidity for at least the next 12 months, supported by cash and operating cash flows.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
