Upsized $300 Million Initial Public Offering

New York, NY, Nov. 4, 2021 — Concord Acquisition Corp III (the “Company”), today announced the pricing of its initial public offering of 30,000,000 units, upsized from 25,000,000 units, at a price of $10.00 per unit. The units are expected to be listed on the New York Stock Exchange (the “NYSE”) and trade under the ticker symbol “CNDB.U” beginning November 4, 2021. Each unit consists of one share of the Company’s Class A common stock and one-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one share of Class A common stock at a price of $11.50 per share. Once the securities comprising the units begin separate trading, the Company expects that its Class A common stock and warrants will be listed on the NYSE under the symbols “CNDB” and “CNDB.WS,” respectively.

The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. While the Company may pursue a merger opportunity in any industry or sector, it intends to capitalize on the ability of its management team and sponsor to identity, acquire and manage a business in the financial services and financial technology sectors, including payments, enterprise software, and data analytics.

Citigroup Global Markets Inc. and Cowen and Company, LLC are serving as the joint book running managers for the offering. The Company has granted the underwriters a 45-day option to purchase up to an additional 4,500,000 units at the initial public offering price to cover over-allotments, if any.
