STRL

Sterling is a high-quality, accelerating business. FY2025 revenue rose 17.7% to $2.49B even after deconsolidating RHB, while operating income jumped 53.4% to $406M and gross profit climbed 34.3% — margins are expanding, not just volume. Operating margin reached 16.3%, net margin 11.7%, and return on equity a standout 26.2%. The five-year arc is textbook compounding: revenue from $1.41B (FY2021) to $2.49B and net income from $62.6M to $290M. The balance sheet is genuinely strong — $391M cash against roughly $291M of total debt (net cash), liabilities/equity of just 1.38x, and $440M of operating cash flow on only $77.3M of capex, signaling an asset-light, high-conversion model with room to fund growth and buybacks ($74.2M repurchased).

The MD&A explains where the durability comes from: the E-Infrastructure segment is levered directly to multi-year data-center, AI, semiconductor and advanced-manufacturing capex from hyperscalers and colocation providers — the strongest secular construction tailwind available. Management is deliberately upgrading mix: shifting Transportation away from low-bid heavy highway toward design-build, and bolting on capability via the $562M CEC specialty electrical/mechanical acquisition and the Drake concrete deal in DFW. The audit is unqualified with no goodwill or long-lived-asset impairments across 2023-2025.
