Guidance

Initial 2026 guidance: 19% revenue growth, 26% Adjusted EBITDA growth

Management provides strong initial 2026 guidance with 19% revenue growth and 26% Adjusted EBITDA growth, citing unprecedented infrastructure demand and record backlog. All segments expected to contribute.

Risks flagged

Free cash flow declined significantly in FY2025 due to growth investments, which may pressure returns if growth slows.

“Free cash flow $342M in FY2025 vs $1,039M in FY2024, a 67.1% decline.”

Margin pressure in Communications segment from ramping new business volume could persist.

“Communications EBITDA margin declined 50 bps to 8.5% due to short-term impact of ramping new business volume.”

Execution risk in maintaining growth trajectory and margin expansion given large backlog and guidance expectations.

“Guidance assumes 19% revenue growth and 26% Adjusted EBITDA growth, which may be challenging to achieve if demand moderates.”
