Liquidity is insufficient, with a current ratio of 0.86 (12.05 in 2024), below 1. Short-term debt is 3.3% and cash 0% of total assets. 83.3% of the assets are financed with debt and provisions.
Calculation

The band follows from the bankruptcy probability. 10 more points roughly halve it.

75-100 Excellent under 0.55%
60-74 Healthy 0.55% to 1.5%
45-59 Fair 1.5% to 4.2%
25-44 Weak 4.2% to 15.0%
0-24 Critical over 15.0%

Where the company stands within its band depends half on the bankruptcy probability and half on how it does against its sector peers (NACE 71, micro). It does better than 20% of them on solvency, 33% on liquidity, 29% on profitability and 37% on growth.

The bankruptcy probability was computed on 02-11-2026 by the bankruptcy model of 2 October 2026, which learns from Belgian bankruptcies and reads the registers, the annual accounts and the Belgian Official Gazette.

Some facts cap the score, however low the probability. With negative or zero equity, a heavy loss, a special status in the KBO, one missing filing or accounts filed more than 90 days late, the score is Fair at most (59). With two missing filings, it is Weak at most (44). During a judicial reorganisation or at the company's end (bankruptcy, dissolution, liquidation), it is Critical at most (24).
