Good morning!

Since Transfix was founded in 2013, our mission has been to deliver simple, smart and sustainable solutions for shippers and carriers, powered by the best people and technology. Throughout our journey we have had the opportunity to work with incredible partners, like you, who help keep America moving every day. Thank you for your partnership and trust over the years.

Today, we are incredibly excited and proud to announce the next step in positioning Transfix for the future — our plans to go public through a merger with G Squared Ascend I Inc. (NYSE: GSQD), a special purpose acquisition company (SPAC) created specifically to bring a private company like ours into the public markets. Subject to customary closing conditions, upon closing of the transaction, the combined company is expected to be listed on the NYSE and trade under the new ticker symbol “TF” in the first quarter of 2022.

This is an exciting and important milestone for us, and we would not be here without you. Myself, our founders - Drew and Jonathan, and the entire Transfix team, continue to be committed to your ongoing success and focused on providing the superior experience you’ve come to expect from us. We anticipate that with the additional capital, this transaction will enable us to deliver even more value to you through the acceleration of innovative products and offerings and the continued expansion of our services.

Thank you for your business and your ongoing partnership. We look forward to growing our relationship for years to come.

Best Regards,

Lily Shen

CEO & President
