CONFIDENTIAL Central Bank Digital Curr e ncies 2 0 21

What is C entral Bank Digi t al Curre n cy? Circle Internet Financial | Confidential | 2 Central Bank Digital Currency (“CBDC”) is a government issued digital form of a country’s fiat currency. Most governments are exploring CBDC and its potential use cases including interfacing at the consumer and retail level. While Central Banks research CBDC, Circle has already created a digital dollar where the underlying asset operates within the regulatory perimeter for financial services in the U.S. Source BIS: “Central bank digital currencies: foundational principles and core features” (October 2020). Atlantic Council: “The rise of Central Bank digital currencies.”

Future of Dollar Digital Currency Innovation If the Federal Reserve were to garner control over the flow of money to the retail level, this would be an unprecedented action and would disrupt the custodianship model currently operating in the U.S. Circle imports all the good conduct and macroprudential expectations that trusted central banks have in their fiat and financial system. Circle Internet Financial | Confidential | 4 Today, the financial services industry operates under two - tier models where central bank policy is transmitted through the private sector. Examples of two - tier models under the Federal Reserve where private firms operate on the core infrastructure: (1) Nacha.org - April 15, 2021 - ACH Network Volume Rises 11.2% in First Quarter as Two Records are Set. (2) Frbservices.org - Fedwire Funds Service - Monthly Statistics. (3) Average daily payments in February 2021. OPERATING UNDER A TWO - TIER MODEL This model creates the autonomy needed to drive innovation in the private market, while maintaining regulatory control. For example, ACH payments volume averaged 118 million payments per day 1 while the Fed processed 800 thousand payments through Fedwire 2 3

USDC design and product market fit is highly supportive of maintaining the U.S. Dollar as the world’s most trusted currency . While other countries are exploring issuing digital currency directly to consumers disintermediating the financial services sector, the U.S. is advancing with a superior model that preserves regulatory oversight and control over monetary policy while harnessing the power of blockchain technology and private market innovation.

CeFi Circle Internet Financial | Investor Presentation, June 2021 | 7

CeFi AUM has experienced an explosive growth trajectory Centralized finance, or “CeFi,” allows individuals to earn interest or borrow funds through a centralized corporation using cryptocurrencies as collateral. Corporations act as lenders and bear custody of their clients’ funds/assets while they put them to use to provide interest for the lenders. Unlike in DeFi lending protocols, lenders transfer risks to these corporations.

DeFi Circle Internet Financial | Investor Presentation, June 2021 | 13

DeFi lending protocols have accelerated despite complex UX to date DeFi broadly refers to smart contracts and protocols that provide decentralized access to traditional instruments like lending and yield products. DeFi protocols are a category of decentralized applications built on top of smart contract - enriched blockchains — primarily the Ethereum network. These protocols inherently democratize and open access to a credit and rates markets for retail and institutional entities worldwide, often with little barrier to entry or arbitrary regulations. We believe that DeFi has the potential for widespread adoption Total USD Value Locked in DeFi Lending Protocols 1 Top Lending Protocols 2 12.2B 11.3B 1 0 . 1 B Medium to long term, DeFi - based infrastructure is expected to have a much larger market share than CeFi.

In the longer term, Circle intends to provide a gateway to the broader set of services that are set to redefine financial infrastructure, much broader than initial borrow / lending capabilities Decentralization of existing financial infrastructure would enable Circle to provide services including escrow, borrowing, tokenized securities and crypto liquidity execution Simple, safe access to radically more efficient Decentralized Finance protocols expected to radically improve, and eventually replace, current financial services architecture.
