Who really paid the interest on JOB AIR Technic's loans?

More aircraft through the hangar, no profit left for the lenders

If you have flown from Ostrava, you may have passed the large hangars at Mošnov airport. That is the home of JOB AIR Technic, a Czech s.r.o. (a limited liability company) that maintains and repairs airliners for airlines. It is a business of big buildings, skilled mechanics and aircraft that must leave on time. In November 2026 the company changed owner and got a new managing director. The numbers they inherit carry one awkward fact.

In 2025 JOB AIR Technic took CZK 1.3bn in revenue, up 29.4% from CZK 992m a year earlier. The figures cover the company on its own, for the calendar year, under Czech accounting standards. Sales are only the first line, though. The operating result, what is left after paying for people, parts, energy and the wear on hangars and tools, did not follow. It was a loss of CZK 7.0m, against a loss of CZK 3.0m in 2024. The operating margin stood at -0.5%.

Now set that next to the loans. Interest expense in 2025 came to CZK 6.1m. A business pays interest out of its operating profit. Here there was no operating profit to pay it from. The lenders were paid, but the repair work did not earn their money.

Why a busier hangar can earn less

Aircraft maintenance looks like a growth business when the order book fills up. The economics are less generous. A heavy check on an airliner needs a hangar slot, a team of licensed mechanics and a long list of parts. The hangar and most of the staff cost the same whether the bays are full or not. Parts are often bought in and passed on to the airline with a thin markup. When a large share of new revenue is material rather than labour, sales jump while margin barely moves.

There is a second squeeze. Mechanics with aviation licences are scarce, and their wages rise faster than many contracts allow prices to. A maintenance shop that signs fixed prices for a season and then pays more for overtime absorbs the difference itself.

The accounts show the pattern, not the cause. EBITDA, the operating result before the charge for the wear on buildings and equipment, was CZK 36.2m in 2025, down from CZK 38.4m. As a share of revenue it fell from 3.9% to 2.8%. So the extra sales of CZK 292m came with less cash earnings, not more. Depreciation of CZK 43.2m then pushed the result below zero. The accounts do not split revenue into labour and parts, and that split is the figure that would show whether the growth is thin by design or thin by accident.

For context, a small benchmark of three Czech companies classified in the same industry had a median operating margin of 4.3% in 2025. JOB AIR Technic sat 4.8 pp below it. I would not lean hard on that comparison, because the group is mixed, but the direction is clear.

The profit came from below the line

Despite the operating loss, JOB AIR Technic ended 2025 with a net profit of CZK 12.9m, after a net loss of CZK 16.1m in 2024. A turn of CZK 29.0m in a single year looks like a recovery. It is not a recovery of the hangar business. With operations in the red and interest to pay, the profit had to come from items below the operating line, such as financial income or one-off gains. The accounts do not show which item it was, and that decides whether the result repeats.

Cash tells the other half. It fell 48.0% to CZK 48.2m at the end of 2025, from CZK 92.6m a year earlier. More work in progress, more parts on the shelf and longer payment terms for airlines all tend to tie up cash when a maintenance shop grows quickly. The accounts do not say which of these applies here.

None of this is a crisis. Equity stood at CZK 905m, which is 68.7% of total assets, a thick cushion for any company. Before depreciation, the operations still produced more than enough to cover the interest. The problem is subtler: the hangars earn their running costs, but not the cost of replacing themselves and paying the bank at the same time.

What it means for airlines, the new owner and anyone with a loan

For the airlines that bring their aircraft to Mošnov, a maintenance provider at break-even is a provider that will look hard at prices. When a new owner arrives at a shop running at a loss, the usual levers are higher rates, fewer fixed-price deals and more selective contracts. That does not mean any of them will be pulled here, but it is where the pressure points.

For the new owner, the first question is simple. Can the hangars carry their own interest from the work they do? In 2025 they could not. The answer for 2026 depends on whether the growth in revenue starts to bring margin with it, not on another good result below the line.

For anyone running a business with a loan, the check is the same one. Divide your operating profit by your interest cost. If the answer is below one, your lender is being paid from somewhere other than your trade. Then repeat the sum with loan rates a few points higher and operating profit a fifth lower. If that version makes you uncomfortable, the time to fix it is before the bank asks.

JOB AIR Technic grew into a bigger hangar business in 2025 and finished the year in profit. The profit came from somewhere other than the hangars, and the new owner now has to make the repairs pay for the loans themselves.
