Summary:

JetBrains s.r.o. went negative because a large foreign-exchange loss overwhelmed a much smaller operating profit. The report explicitly identifies CZK 1.516 billion of currency losses caused by the Czech koruna strengthening against major foreign currencies. But “it was just accounting” would be incomplete: operating profit also fell 63.2%. These accounts use Czech accounting rules, not IFRS.

So two separate things happened: operations deteriorated by CZK 1.291 billion, and the financial result deteriorated by CZK 2.016 billion. Lower taxes cushioned the fall rather than causing it. Approximately 61% of the deterioration before tax came from the financial section and 39% from operations.

For cash generation, the reported operating cash flow is positive—but requires caution. It increased from CZK 5.059 billion to CZK 6.353 billion. However, the 2025 statement includes CZK 6.672 billion of positive net working-capital adjustments, while its before-working-capital subtotal is negative CZK 60.926 million. The positive final figure therefore should not be read as CZK 6.353 billion of recurring cash earnings.

Removing only that disclosed currency loss would produce CZK 1,191.121 million of profit before tax. That is a mechanical sensitivity calculation—not an IFRS profit figure or a fully currency-neutral result. It leaves derivative gains and all other reported amounts unchanged, and it should not be treated as adjusted after-tax profit. The report says the 2025 “other financial income” line consists mainly of derivative income.
