Additional factors that may affect the future results of Twilio and SendGrid are set forth in their respective filings with the SEC, including each of Twilio’s and SendGrid’s most recently filed Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the SEC, which are available on the SEC’s website at www.sec.gov.
