The starting point is the disappearance of the pandemic windfall.
From 2022 revenue of KRW 853.6bn and operating profit of KRW 196.5bn (a 23.0% operating margin), revenue collapsed to KRW 367.4bn in 2023 with an operating loss of KRW 30.1bn, and 2024 stayed in the red with revenue of KRW 414.3bn and an operating loss of KRW 16.5bn.
In 2025 revenue reached KRW 474.2bn, up roughly 14%, with operating profit of KRW 34.5bn (a 7.3% margin) and net profit attributable to owners of KRW 48.3bn, restoring profitability at the operating line.
Quarterly, the path ran from 2Q25 revenue of KRW 114.1bn with operating profit of KRW 3.1bn and a KRW 0.1bn net loss to owners, through KRW 113.5bn and KRW 9.6bn in 3Q25 and KRW 130.6bn and KRW 6.9bn in 4Q25, to 1Q26 revenue of KRW 129.1bn with operating profit of KRW 23.6bn (an 18.2% margin) and 2Q26 revenue of KRW 136.0bn with operating profit of KRW 21.6bn (15.9%) - a clear step up in margin level.
First-half 2026 totals were revenue of KRW 265.1bn, operating profit of KRW 45.1bn and net profit to owners of KRW 60.7bn.
Management attributed the first-quarter improvement to a 32.6% rise in non-respiratory syndromic sales, HPV tender wins and wider entry into screening markets, demand shifting to PCR, and better cost structure and expense control.
That said, Daol Investment & Securities wrote in a July 2026 report that the first quarter included one-off items such as a reversal of equipment valuation losses, with that effect fading in the second quarter, so the 1Q26 margin should not be read as a steady-state level.
Repeated quarters in which net profit exceeded operating profit point to sizeable non-operating contributions such as interest income from a net-cash balance sheet and foreign-exchange items, which makes quarterly net income more volatile than operating profit.
Cash generation has been firmer than reported earnings, with operating cash flow of KRW 149.3bn in 2025 versus KRW 85.4bn in 2024 and KRW 94.9bn in 2023, and at end-2025 total equity stood at KRW 1,015.8bn against total liabilities of KRW 220.0bn, a 21.7% debt-to-equity ratio.
