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 43, small). It does better than 23% of them on solvency, 13% on liquidity, 51% on profitability and 74% on growth.

The bankruptcy probability was computed on 09-11-2026 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.

The probability rests on the annual accounts with balance sheet date 31-12-2025.

Of the companies with a bankruptcy probability in the low class on 30-06-2025, 0.8% went bankrupt within twelve months.

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).

Comparable companies, two years later

In July 2024, 4,107 companies had the same profile as ISOLUTION has now. Each dot stands for 11 companies, two years later.

97.9%
were still trading
0.9%
stopped another way
1.0%
went bankrupt
  • Small
  • 10 to 20 years old
  • solvency 10 to 30%
  • a profit under 5% of the balance sheet

Another 0.2% stopped without a precise date, possibly only after those two years.

That fits the bankruptcy probability of ISOLUTION itself: 0.6% within 12 months.

Test of the method

The method was tested on the 497,447 companies of July 2024. Each company was given the bankruptcy share of the same profile a year earlier, in July 2023. The expectation was that 1.6% would go bankrupt within 24 months. In fact 1.7% went bankrupt.

The companies in ten equal groups, from the lowest to the highest expected share
Group Expected Actual
1 0.2% 0.2%
2 0.3% 0.5%
3 0.5% 0.6%
4 0.7% 0.8%
5 0.9% 0.9%
6 1.3% 1.5%
7 1.6% 1.8%
8 1.8% 1.8%
9 3.0% 3.1%
10 5.6% 6.2%

A company that went bankrupt had a higher expected share than one that kept going in 74.5% of comparisons. The level depends on the economy. In a year with more bankruptcies than the year before, the actual share is higher than the expected one.

This is an observation about 4,107 companies, not a prediction for ISOLUTION. The sector does not count, because the KBO no longer lists a sector for a company that has stopped. By sector, mostly the survivors would count, which would paint too rosy a picture.

Credit verdict

Credit of up to €30,000 on 30-day terms is acceptable

Liquidity is tight, with a current ratio of 1.11 (1.23 in 2024), below the usual 1.5. Short-term debt is 68.9% and cash 6.7% of total assets. 78.8% of the assets are financed with debt and provisions.
