(Nasdaq: GMII, GMIIW and GMIIU), a special purpose acquisition company formed by affiliates of The Gores Group and Metropoulos & Co., announced strategic amendments to the terms of their previously announced definitive agreement (the “Merger Agreement”) to combine. These amendments and associated incremental investments by leading institutional investors to adapt to current market conditions strongly position Sonder for long-term growth, and underscore Sonder’s and Gores Metropoulos II’s collective commitment to driving long-term value creation for all stockholders.

As part of the amended terms of the transaction, the combined company’s implied pro forma enterprise value will be $1.925 billion. Sonder will receive approximately $110 million in additional capital from affiliates of Gores Metropoulos II and other leading investors, including Fidelity Management & Research LLC, funds and accounts managed by BlackRock, Atreides Management, LP, and Senator Investment Group (the “New PIPEs”), in addition to the $200 million previously announced PIPE (the “Existing PIPE”). Moreover, Sonder has signed a non-binding term sheet for Delayed Draw Notes of $220 million with existing PIPE investors, to be available following the closing of the proposed business combination, which enables the Company to fund its growth over the next several years.

“Sonder continues to generate impressive results amid the ongoing recovery of the travel industry and is well positioned for future growth given their unique value proposition. We strongly believe that Sonder is the hospitality brand of tomorrow and have high conviction that the company will continue to grow, which is why we are increasing our initial investment,” said Alec Gores, Chairman and CEO of The Gores Group and CEO of Gores Metropoulos II. “In response to evolving market dynamics, we are also amending the terms of our merger agreement, reflecting our commitment to driving long-term value creation, transparency and stockholder alignment in this high-performing and innovative business.”

“We continue to see a rebound in leisure travel, and we are aggressively pursuing our expansion plans and capturing significant consumer demand. We reported company-record quarterly revenue in Q2 and are eager to pursue continued growth,” said Francis Davidson, Co-Founder and CEO of Sonder. “We’re thrilled to have a committed and creative partner in Gores and the amendments, and incremental investment announced today will allow us to pursue our ambitious growth and expansion strategy in full force. In the past year alone, we’ve launched in three additional countries and expanded our operations in dozens of other markets, and we expect to continue to scale our business and innovate to adapt to the needs of emerging traveler segments like digital nomads.”

Sonder recently announced its entry into France with the opening of a property in Paris near the iconic Champs-Élysées, as well as large expansions of its operations in the Middle East and Mexico. The Company also launched a corporate travel offering, opening its doors to even more business travelers and continues to grow its extended stays offering to capture new traveler groups.
