Korean corporate sales rise 26.7 percent as margins expand
South Korean non-financial corporations recorded a 26.7 percent year-on-year sales increase in the second quarter of 2026, alongside improved profitability and lower debt ratios, according to Bank of Korea financial statement data.
Manufacturing leads revenue and margin gains
Corporate top-line revenue expanded across South Korean enterprises in the second quarter of 2026, with sales increasing 26.7 percent year-on-year, up from 13.5 percent in the first quarter.
Total assets rose 6.8 percent year-on-year, compared to 0.2 percent in the second quarter of 2025.
Profitability indicators also strengthened, as the operating income to sales ratio rose from 5.1 percent to 16.9 percent over the same period.
The pre-tax income to sales ratio advanced to 23.1 percent from 5.3 percent.
In manufacturing, sales grew 39.6 percent, operating margins reached 24.0 percent, and pre-tax profit margins climbed to 34.0 percent.
Deleveraging cushions balance sheets
Corporate balance sheets also strengthened during the period.
The average debt-to-equity ratio fell to 84.5 percent at the end of June from 87.0 percent at the end of March, with manufacturing debt declining to 65.7 percent.
Total borrowings and bonds payable relative to total assets declined to 22.8 percent from 23.9 percent.
The survey covers 4,260 externally audited non-financial corporations using stratified systematic sampling from the national business register.
A flattering top-line narrative
The sharp margin expansion highlights strong operational resilience among large corporate exporters.
However, the heavy concentration of gains in manufacturing obscures vulnerabilities in smaller domestic sectors.
Relying on top-tier balance sheet strength risks masking broader credit risks across the economy.
