Looking at annual results, CTK posted a heavy loss in 2022 with revenue of KRW 69.4 billion, an operating loss of KRW 15.2 billion (operating margin of -21.9%), and a net loss attributable to owners of KRW 17.7 billion, before turning profitable in 2023 with revenue of KRW 88.9 billion, operating profit of KRW 2.7 billion (margin 3.1%), and net income attributable to owners of KRW 6.9 billion.
In 2024, however, revenue slipped slightly to KRW 83.6 billion and operating profit shrank to just KRW 0.13 billion (margin 0.2%), while net income attributable to owners swung back to a loss of KRW 3.3 billion.
In 2025, revenue grew again to KRW 89.2 billion, but the operating loss widened to KRW 5.7 billion (margin -6.4%) and the net loss attributable to owners expanded to KRW 7.0 billion.
The company attributed the top-line growth to newly consolidated subsidiaries and higher sales at key subsidiaries, while explaining the deteriorating bottom line as a result of one-off costs from equipment maintenance and facility relocation, rising interest expense, and fluctuations in foreign exchange and financial asset valuation.
On a quarterly basis, Q2 2025 saw revenue of KRW 22.5 billion, operating profit of KRW 0.23 billion, and net income attributable to owners of KRW 1.25 billion, but Q3 2025 revenue rose to KRW 31.1 billion while the company swung to an operating loss of KRW 4.06 billion and a net loss of KRW 4.59 billion; Q4 2025 revenue fell to KRW 16.0 billion with an operating loss of KRW 2.21 billion and a net loss of KRW 3.62 billion.
Q1 2026 posted revenue of KRW 24.5 billion with an operating loss of KRW 1.74 billion and a net loss of KRW 4.28 billion, but Q2 2026 revenue rose to KRW 29.0 billion with an operating profit of KRW 0.47 billion, ending three straight quarters of operating losses.
Even so, net income attributable to owners in Q2 2026 remained negative at KRW -1.98 billion despite the operating profit turnaround, indicating that non-operating items such as financial costs and foreign exchange effects continue to weigh on the bottom line.
On the cash flow side, operating cash flow was negative in every year except 2023 (KRW +10.6 billion), registering KRW -8.8 billion in 2022, KRW -7.2 billion in 2024, and KRW -8.2 billion in 2025, while the debt ratio also jumped sharply from 22.1% in 2024 to 75.5% in 2025, marking a notable shift in the balance sheet structure.
