Telegram hit by $500M Russian bond freeze

A few interesting quotes about (unaudited) financials:

> According to previously unreported half-year disclosures, Telegram had $910mn in cash and cash equivalents at June 30, up from $142mn a year prior.

> Telegram’s revenues in the first half of 2025 jumped more than 65 per cent to $870mn, compared with $525mn in the same period the previous year.

> Nearly a third of Telegram’s revenue — or $300mn — came from so-called exclusivity agreements (probably related to the toncoin cryptocurrency)

> Advertising revenue was up 5 per cent to $125mn in the first half of the year. Meanwhile, premium subscriptions jumped 88 per cent to $223mn, compared with $119mn in the same period in 2024 as the number of paying users rose.

Is it me or the remaining 25% of the revenue sources (222mn of 910mn) are not detailed at all?
