Samsung Heavy Industries delivered a defining quarter in the emerging shipbuilding supercycle. Operating profit of ₩273.1 billion surged 121.9% from ₩123.1 billion a year earlier, and the operating margin nearly doubled from 4.93% to 9.41% — two metrics that confirm the structural inflection point from loss-cycle trough to sustained margin recovery. Revenue grew 16.4% to ₩2,902.3 billion, but operating profit expanded at roughly 7.4 times that rate, demonstrating precisely how the industry's heavy fixed-cost base behaves when high-priced order intake meets rising utilization. Simultaneously, the balance sheet underwent accelerated rehabilitation: operating cash flow reversed from negative ₩131.1 billion to positive ₩1,488.8 billion, funding aggressive debt reduction and driving net debt-to-total capital from 23.75% to 3.42% within a single quarter. Against that backdrop, however, reported net income rose only 11.0% to ₩100.0 billion — and that gap between operating profit growth and bottom-line outcome is where the analysis that matters most begins.
