Circle Internet Group stock tumbled more than 5% in extended trading Tuesday after it said it would offer 10 million Class A shares to the public. Two million of the shares will be offered by the company, and 8 million shares will be sold by existing shareholders.

Circle has completed its first quarter as a public company, reporting $658 million in returns on its stablecoin reserves — its main source of profit — while holding onto $251 million of that after distribution costs.
