Cyborg Score Rationale
DEME holds a market-leading position in marine engineering with 150 years of heritage, a global presence across five continents, and diversified revenue streams across high-demand sectors (renewable energy, port infrastructure, offshore). However, it operates in cyclical sectors and faces execution risks on large projects. Growth is driven by global energy transition and climate adaptation needs.
