Summary
Korund9 is a financial institution; the bankruptcy model is trained on trading and manufacturing companies and does not apply here. The 2025 annual accounts show equity of €1.3m and a net result of -€2.2m. Equity is growing by ~14% per year across the filed fiscal years. Its solvency ranks better than 6% of 2473 sector peers (fiscal year 2025). The company has been active since 2016 and the Belgian State Gazette contains no insolvency or warning signals.
Checked score
Outside the general model
Model not applicable to financial institutions
The Checked score weighs liquidity, leverage and margins against norms for trading and manufacturing companies. A bank, insurer or financial holding has a fundamentally different balance-sheet structure, so those ratios, and hence the score, carry no meaning here. That is why we show no financial axes either.

○neutral
neutral · A punctual record breaks
This company filed 3 consecutive financial years on time. The year that closed on 31-12-2025 was due by 31-07-2026 and was filed on 24-08-2026, 24 days late. Weigh it accordingly: a break into the 1-to-90-day band measures 1.41% abnormal legal state, below the 1.66% market average. It is a change in behaviour, not evidence of elevated risk.

Not every act has been read: a resignation may be missing here
22 of this company's 24 Belgian State Gazette acts have not been read yet. Appointments and resignations recorded in them are missing above: a director who resigned there may therefore still show here as sitting. The acts are in the Timeline.
