Checked score
About 8 in 1,000 comparable companies go bankrupt within 12 months (an estimate).
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 41, micro). It does better than 92% of them on solvency, 91% on liquidity, 22% on profitability and 25% on growth.
The bankruptcy probability was computed on 31-10-2026 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).

The operating result for 2025 is a loss of €3,659, larger than the loss of €260 in 2024. It is the lowest result since 2021.
Turnover is what the company sold, the result is what was left of it. A loss stands below the zero line.
Assets, equity and debt per financial year.
Above zero, the company can pay its short-term debts with what it holds in the short term.
The EBIT margin is the share of each euro of turnover left from operations. The return on assets is what the assets earn.
The higher the solvency, the better the company absorbs a setback.
A ratio above 1 means the short-term assets cover the short-term debts.
Use the arrow keys on the chart for the figures per year.
The sector band is the middle half of the companies in Construction of residential and non-residential buildings (NACE 41). A quarter of them sit below it, a quarter above. Each year counts only accounts in the same format, and only where there are at least 30. The dashed line is the median. There is a sector band for net result, equity, total assets, working capital, solvency, current ratio and return on assets (ROA).
Comparable companies
These companies have the same main activity as JST CONSTRUCT: general construction of residential buildings (NACE 41001). They are comparable in size and age: total assets between €48,300 and €66,300, founded between 2017 and 2019.

Companies with the same profile, two years later
Historical observationIn July 2024, 3,440 companies had the same profile as JST CONSTRUCT has now. Two years later, 2.3% had gone bankrupt and 90.1% were still going.
- Micro
- 5 to 10 years old
- solvency 30% or more
- a small loss
Another 0.2% stopped without a precise date, possibly only after those two years.
That fits the bankruptcy probability of JST CONSTRUCT itself: 0.8% within 12 months.
Test of the method
The method was tested on the 497,445 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.
| 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 3,440 companies, not a prediction for JST CONSTRUCT. 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.

A Belgian filing has no cash-flow statement. These rows are therefore an approximation, derived from the income statement and the balance-sheet moves.
