Radionor Communications grew revenue fast and still ended the year holding more cash

Revenue went up steeply, and the cash went up with it

Radionor Communications AS is a Norwegian maker of radio communication equipment based in Trondheim. An AS (aksjeselskap) is a Norwegian private limited company, roughly the equivalent of a Czech s.r.o. The figures below cover the company on its own, in Norwegian kroner, for calendar years.

In 2023 the company took NOK 229m in revenue. In 2024 it took NOK 1.0bn. In 2025 it took NOK 2.5bn. That is average growth of 228.1% a year over the period, and 143.3% in the latest year alone.

Growth at this pace normally comes with a bill. More orders mean more components bought in advance, more stock on the shelves, more invoices waiting to be paid and more people hired before the revenue arrives. Fast-growing manufacturers often report rising profits and a shrinking bank balance at the same time. Radionor did the opposite. Cash rose by NOK 1.2bn to NOK 1.9bn at the end of 2025, an increase of 192.6%. Operating profit, the profit from running the business before interest and tax, reached NOK 2.0bn, up 150.2% from NOK 809m.

So the tension is this: a company growing faster than almost any industrial business can sustainably grow did not need outside money to do it, and it became more profitable per krone of sales on the way.

A margin this wide changes how growth behaves

The operating margin, the share of each krone of revenue left after operating costs, was 79.7% in 2024 and 82.0% in 2025, a widening of 2.3 pp. The net margin, what remains after tax and financial items, rose from 63.8% to 64.9%.

Those are unusual numbers for a company that makes physical equipment. In most manufacturing, materials and wages take the bulk of revenue, and an operating margin in the low teens counts as good. When more than four fifths of revenue survives as operating profit, the usual growth mechanics flip. Each new order costs little to deliver relative to what it brings in, so the profit from this year's sales can fund the stock and receivables needed for next year's, with plenty left over.

The balance sheet bears that out. Equity, the owners' stake in the company, rose by NOK 1.4bn to NOK 2.2bn, while net profit for 2025 was NOK 1.6bn. Most of the year's profit therefore stayed inside the company rather than leaving as dividends. The equity ratio, equity as a share of total assets, moved from 68.2% to 72.6%. Total assets grew from NOK 1.1bn to NOK 3.0bn, and cash makes up most of that.

Why the margin is so wide is a separate question, and the accounts do not answer it. The usual candidates in a business like this are a product with little direct competition, contracts priced on capability rather than on cost, a cost base that was built earlier and has not yet had to grow, or a handful of very large orders. Each points to a different future. A product edge can last years. A cost base that has not grown yet will grow. A few large orders can end with the next budget cycle. The figure that would settle it is revenue split by customer and by contract length, and the company's annual accounts do not show that split.

The risk is not cash, it is the base the growth was built on

The lead problem in fast growth is usually financing. Here it is not. The risk sits elsewhere: in the expectations that a run like this sets for everyone, inside the company and outside it.

When revenue rises 228.1% a year on average, hiring plans, supplier commitments, production capacity and the board's view of what a normal year looks like all adjust upwards. That is rational while orders keep coming. It also means the cost base is quietly being sized for the next step up. If revenue merely holds steady at NOK 2.5bn, a level that would have looked extraordinary in 2023, the margin will start to fall as those costs arrive. A flat year after a steep climb can feel like a decline even when it is not.

The company also has new people at the top. The Norwegian business register, Brønnøysundregistrene, records a new chief executive (daglig leder), a new chair of the board and several new board members. A change of leadership after a period like this is common. The new team inherits a strong balance sheet, and also the job of deciding how much of the recent growth to treat as the new baseline.

What to check in your own company

You do not need Radionor's margins to run the same test. Take your last three financial years and put three lines side by side: revenue, operating profit and cash at year end. Then work out how much cash grew for every krone, euro or koruna of operating profit over the same years. If revenue and profit rose and cash did not, the growth was financed by stock, unpaid customer invoices or a credit line, and someone is carrying that bill.

Then do the harder half. Ask your finance team which costs were added in the past two years because of growth you expected, not growth you already had: people hired ahead of demand, leases signed for capacity, minimum volumes agreed with suppliers. Add them up and compare the total with your operating profit. That number tells you how a flat year would look, which is more useful than knowing how a good one looks.

Finally, look at your revenue by customer. If your largest few customers account for most of the increase, the trend is a set of relationships, not a market, and each one has its own renewal date.

Radionor Communications grew fast and ended 2025 with more cash, more equity and a wider margin than it had in 2023. Its accounts show a company that can afford its growth. What they cannot show is whether that growth is a level or a peak, and that is the question the new management will be judged on.
