Aton said its consolidated operating profit for the second quarter of 2026 rose 92.3% from a year earlier to 3.2 billion won ($2.3 million), lifting operating margin by 9.7 percentage points to 18.1%. Revenue for the quarter fell 11.4% to 17.4 billion won ($12.3 million), while first-half revenue totaled 32.3 billion won ($22.9 million). The company said the sales decline reflected a base effect from large projects concentrated in the prior-year period, but earnings improved as it adjusted its business portfolio, expanded higher-margin operations and improved profitability at consolidated subsidiaries despite revenue adjustments tied to business mix changes. In the first half, Aton expanded its post-quantum cryptography, or PQC, business beyond banks and securities firms to virtual-asset exchanges and fractional investment platforms, while continuing to win financial infrastructure and digital-asset work. Through Project Hangang Phase 2, a follow-up to the Bank of Korea-led CBDC pilot, Aton secured system implementation references for NH NongHyup Bank and KB Kookmin Bank and won additional contracts for core banking systems and financial service buildouts at major banks. The company said revenue from those projects is expected to be recognized sequentially in the second half as development progresses, and it plans to further raise the share of higher-margin solutions and licensing revenue while expanding its Security Center business into the broader enterprise market.
