“The closing of 4D pharma’s merger with Longevity represents a transformational milestone for the Company,” commented Duncan Peyton, Chief Executive Officer, 4D pharma.
“Becoming a dual-listed company both in the UK and the US broadens our global reach. In conjunction with the NASDAQ listing, the closing of the merger and concurrent fundraise give 4D pharma an additional $40 million of capital and puts the company in a very strong financial position to execute across our robust pipeline,” he added.
In connection with the merger, 4D has also issued new warrants convertible into ordinary shares, which, if exercised, would bring in an additional $29 million.
