• Engineering & specialty facilities: design & build for semiconductor fabs, pharmaceutical plants, data centers.
• Consulting & services: project management, environmental engineering, safety/compliance advisory.
• Renewable energy & infrastructure investments: EPC and ownership stakes in solar, wind, hydrogen projects.

• Contract revenue - fixed‑price, cost‑plus and milestone billing on construction and civil engineering contracts domestically and overseas; large EPC contracts generate most project revenues.
• Real estate income - one‑time gains on property sales and recurring rental income from retained investment properties and leased developments.
• Engineering & O&M fees - lump‑sum and fee‑based work for highly specialized facilities (semiconductor, pharma), plus long‑term maintenance contracts.
• Consulting & advisory fees - fee income from pre‑construction planning, environmental remediation, and safety/compliance services.
• Investment returns - returns and recurring cash flow from renewable energy assets and infrastructure equity stakes; capital recycling through asset sales.
• Strategic M&A - acquisitions expand capabilities, client access and geographic reach (e.g., purchase of GCON Inc. in October 2025 to broaden offerings and revenue potential).

• Progress billing: recognized as construction stages complete; cash timing tied to milestone certification and retention release.
• Backlog conversion: a multi‑year pipeline-order backlog converts to recognized revenue as projects progress.
• Margin variability: project complexity, fixed‑price exposure, commodity and labor cost movement affect margins; risk management and subcontractor control are key.
• Recurring income: property leasing and O&M contracts smooth cyclicality from lump‑sum project revenues.

• Integrated EPC + developer model: captures upstream development gains and downstream construction fees.
• Specialty engineering focus: profit enhancement via high‑margin, high‑spec projects (semiconductor fabs, pharmaceutical facilities).
• Sustainability pivot: investment in renewables and green construction supports new contracted work and recurring asset income.
• M&A & partnerships: inorganic expansion (e.g., GCON Inc., Oct 2025) to add technical capabilities and market access, increasing tender competitiveness.

• Order intake and backlog - signals future revenue and capacity utilization.
• Gross/operating margins by segment - indicates project pricing power and execution efficiency.
• Net property holdings and recurring rental yields - stability of non‑project cash flows.
• Capex and investment in renewables - scale of new recurring-asset generation.
