Date: March 26, 2021

This morning, we announced that an agreement has been reached for MSG Entertainment to acquire MSG Networks. We believe that this transaction would benefit both companies, as together, our businesses would be stronger and better positioned to support our long-term plans. For MSG Networks, that would mean benefiting from being part of a larger company with significant growth potential.

MSG Entertainment and MSG Networks share a long history, and this would clearly be a homecoming for MSG Networks as we would, once again, join forces to build on a shared legacy of delivering exceptional entertainment and media experiences. We are continuing to work through the transaction and expect to close the transaction in the third quarter of calendar 2021. Until then, let’s stay focused on the work at hand and continue to bring the passion and dedication that make MSG Networks such a great success. Thank you for all you do to make that success a reality.

We will keep you updated as we have more information to share. If you have any questions in the meantime, please feel free to reach out to me or your manager.

Thank you.
