| (1) | See “—Non-GAAP financial measures” for reconciliation of Adjusted EBITDA to net income (loss) 
 from continuing operations.                                                                   |

USDC in circulation and average USDC in circulation USDC in circulation is the total amount of USDC minted and outstanding as of the end of the reporting period. Average USDC in circulation is calculated as the simple daily average of USDC in circulation, with the daily USDC in circulation determined at the end of each day. In each case, we exclude:

| • |     | “tokens allowed but not issued,” which are tokens that exist on the Algorand, Hedera, Polkadot, and                                                                                                                                                    
 Solana blockchains due to the technical implementation of USDC on those blockchains. These tokens are held by us in restricted, segregated “tokens allowed but not issued” blockchain addresses. We do not receive any funds for their                 
 creation, and they are not redeemable for the U.S. dollar. These tokens are restricted for use while held in such blockchain addresses. These tokens cannot be redeemed for the U.S. dollar as the private keys are securely controlled by us and the  
 blockchain addresses are not configured to allow redemption requests to be established by Circle Mint. When a minting request is received for USDC on these blockchains and the funds underlying such request is received, the corresponding amount of 
 “tokens allowed but not issued” is transferred from the segregated “tokens allowed but not issued” addresses to the minting address via a system controlled process administered by us, at which point the tokens are considered to                    
 be USDC in circulation.                                                                                                                                                                                                                                |

| • |     | “access denied tokens,” which are tokens that are restricted from being accessed by the holder to                   
 comply with a law, regulation, or legal order from a duly recognized and authorized court of competent jurisdiction |
