Exhibit 99.5

FAQ

Q: What is a SPAC?

A: SPAC stands for Special Purpose Acquisition Company. It is a publicly traded company created for the purpose of acquiring or merging with an existing company, like Quantum-Si.

Q: Are we being acquired? Will the company’s name stay the same, or are we becoming HighCape?

A: At the closing of the transaction, we will be combining with HighCape Capital Acquisition Corp. Upon completion of the transaction, the combined company will operate as Quantum-Si Incorporated. The publicly traded entity will be renamed Quantum-Si Incorporated and will be listed on the NASDAQ under the QSI ticker symbol.

Q: Why are we going public through a SPAC?

A: Working with a top tier institutional investor as a vehicle to enter the public market is a streamlined and efficient way to tell the compelling story of Quantum-Si’s success and continued growth potential in disrupting the proteomics space.

We are thrilled to partner with HighCape Capital Acquisition Corp. to help usher Quantum-Si into its next phase of growth and reach our full potential as we work to revolutionize the growing field of proteomics with our first next-generation protein sequencing platform. This combination will enable us to continue our efforts to democratize medicine, by developing the field of proteomics to make a significant impact on drug discovery, academic research, and diagnostics in the years to come.

Q: When will we go public?

A: The next step involves HighCape Capital Acquisition Corp. submitting certain filings to the Securities and Exchange Commission, or the SEC, which will provide additional information about the transaction and the company going forward, and will be publicly available. The SEC will then engage in a comment and review process involving the proposed disclosure. Once the SEC review process is complete, and subject to certain other closing conditions of the transaction, we expect to complete the combination and become a public company with securities listed on the NASDAQ in the second quarter of 2021.

Q: How does this change our jobs until we go public?

A: Our jobs and our mission remain the same. Now more than ever it’s critically important that everyone remain focused on delivering upon our near- and long-term goals. In the initial period after the announcement and later as a public company, compliance with company policies, especially those involving communicating with the press and trading in company securities, will become extremely important. We will be working through public company-readiness requirements and will provide more information to employees before the closing.
