Email to 25k+ pre-registrations in Reg A Sale Subject Line: Following up on your Blockstack Pre-registration Hi (name), I oversee Investor Relations at Blockstack and I wanted to connect with you directly in advance of our potential Reg A offering. I see that you’ve requested an amount of $$ in the pre-registration. I'm here to answer any additional questions about the project and the sale. I look forward to hearing from you to discuss your interest. Thank you, Brittany Laughlin Investor Relations, Blockstack PBC Important Disclaimer: This communication may be deemed “testing the waters” material under Regulation A under the Securities Act of 1933. We are not under any obligation to complete an offering under Regulation A. We may choose to make an offering to some, but not all, of the people who indicate an interest in investing, and that offering might not be made under Regulation A. We will only be able to make sales after the Securities and Exchange Commission (SEC) has “qualified” the offering statement that we have filed with the SEC. The information in that offering statement will be more complete than the information we are providing now, and could differ in important ways. You must read the documents filed with the SEC before investing. No money or other consideration is being solicited, and if sent in response, will not be accepted. No offer to buy the securities can be accepted and no part of the purchase price can be received until the offering statement filed by the company with the SEC has been qualified by the SEC. Any such offer may be withdrawn or revoked, without obligation or commitment of any kind, at any time before notice of acceptance given after the date of qualification.

An indication of interest involves no obligation or commitment of any kind.
