Leading Independent Proxy Advisory Firm ISS Recommends Avalara Shareholders Vote “FOR” the Transaction with Vista Equity Partners

Avalara Urges Shareholders to Vote “FOR” Value Maximizing Transaction on WHITE Proxy Card

SEATTLE, WA – September 30, 2022 – Avalara, Inc. (NYSE: AVLR), a leading provider of tax compliance automation for businesses of all sizes, today announced that leading independent proxy advisory firm Institutional Shareholder Services (“ISS”) has recommended that shareholders vote “FOR” the pending transaction with Vista Equity Partners (“Vista”) at the Company’s upcoming Special Meeting of Shareholders (the “Special Meeting”) scheduled for October 14, 2022.

In its September 30, 2022, report, ISS noted¹:

The Company is pleased that ISS shares its belief that the transaction with Vista is in the best interests of all Avalara shareholders and supports the Board’s unanimous recommendation that shareholders vote FOR the transaction. The transaction with Vista delivers significant, immediate and certain value to shareholders, eliminating shareholders’ exposure to the execution risks and significant macroeconomic headwinds associated with continuing as a standalone company. The Company strongly urges all Avalara shareholders to follow the recommendation of ISS by voting “FOR” the value maximizing transaction with Vista on the WHITE proxy card today to receive $93.50 per share in cash.

The transaction is expected to close in the second half of 2022, subject to customary closing conditions, including approval by Avalara shareholders.
