Vivid Seats Team -


I am excited to share the news about an important milestone for our company. Today, we announced that Vivid Seats will become a public company, by merging with Horizon Acquisition Corporation, a special purpose acquisition company, or SPAC.


This is a major step for our company, our partners, our customers, and our entire team. As a public company, we expect that we will be able to accelerate the growth of our business – and this transaction marks Horizon Acquisition Corp.’s confidence in the strength of our business model as a leader in the secondary ticketing marketplace and in our growth potential as a public company. Accessing this capital presents a true opportunity for our entire team.


However, as exciting as this is, we must all remember that this announcement is a milestone, not an endpoint. And while celebration is certainly deserved, it’s important that we remain focused on continuing to execute our responsibilities every day.  If anything, it is more important than ever we remain fiercely dedicated and laser focused on all of our efforts.  As events start safely opening up to fans, we stand poised with a unique opportunity to truly disproportionately catalyze growth and deliver unparalleled value to our buyers, sellers, and partners.





Additionally, it is critical that everyone recall that confidentiality is more important now than ever; sharing confidential details cannot only jeopardize this go-public deal, but could also put the company, and any individuals that leak information, in serious legal trouble with regulators, including potential criminal liability.


Public Company Communications


As a publicly-traded entity, Vivid Seats will have certain responsibilities to investors, regulators, and our employees, while continuing our commitment to transparency and accountability. Unlike privately-held companies, our company will have an increased need to disclose financial information in quarterly earnings reports. Here are some of the other updates that you should keep in mind for our next step:


·Employees cannot share information, especially around important events such as earnings announcements, acquisitions, contracts and awards, and other events material to Vivid Seats’ value that may impact our stock price.
 ·Employees cannot disclose material non-public information to outsiders, including information related to earnings, takeovers, security offerings, or litigation.
 ·Employees cannot have, or benefit from, material information (including information about new contracts, new acquisitions, and other information) before other shareholders/investors are made aware of these developments.


The “Frequently Asked Questions” document attached to this email expands on these points, covering questions related to the transaction itself, employee impact, customer impact, public company regulations, and our overarching business strategy moving forward. Please review the document comprehensively, as it addresses many potential questions or concerns.


Social Media


Attached please also see some guidelines related to commentary on social media. We do encourage you to like and share our social media posts across your own channels to celebrate this news, and we request that you please keep these guidelines in mind across:


 ·And any other platforms you use





Media Policy


And finally, as a reminder, Vivid Seats’ Communications Policy states that only approved spokespeople may speak to the media. Please do not comment on the transaction announced today. If any media reach out, direct them to Michael O’Neil using the below message:


“Thanks for reaching out, however, I am not a Vivid Seats spokesperson. Please contact our media team via email at


This process helps mitigate risk and ensures we’re following the appropriate protocols. Thanks in advance for everyone’s help.


Moving Forward


In the coming weeks, we will go through a regulatory review process and work through other closing conditions before we close the transaction. Once we have closed the transaction, expected in the third quarter of this year, we will become a publicly listed company, and trading will begin.


If you have any questions or concerns, please reach out to me directly or your senior leader, and let us know how we can help.


I am so proud and humbled to work alongside all of you – this is only one part of our plan to Emerge Stronger and I couldn’t be more excited to help fans experience it live!  Thank you for all of your decisively united efforts in working so hard to achieve this milestone.  The gates are here and we’re bursting through!


We will host a town hall later today to review this and provide a live update as well.
