The eye-popping $4.8 billion sticker price on Spark Therapeutics’ acquisition deal with Roche announced on Monday is shaping up to be the largest exit ever within city limits for a venture-backed company, according to data from financial data provider PitchBook and the Philadelphia Alliance for Capital and Technologies (PACT).
“Filtering down to just Philadelphia proper does reveal that Spark Therapeutics, once the deal closes, will be the biggest exit ever for Philly-based venture-backed exits,” the company said in an email, citing data from an upcoming report.
According to the Seattle-based company’s data, the current holder of the largest Philly-proper exit title goes to Avid Radiopharmaceuticals, which in 2010 announced its acquisition by Lilly in a deal valued at up to $800 million.
Founded in 2013, Spark is a publicly traded spinout of Children’s Hospital of Philadelphia (CHOP), which invested $33 million in the company. The Philadelphia Inquirer reports that CHOP stands to reap a total return of $430 million for its minority stake in Spark Therapeutics.
As part of the acquisition deal, the company will remain based out of 3711 Market St., and continue to do business as a standalone Roche company.
“This transaction demonstrates the enormous value that global biotech companies like Roche see in gene therapy, a field in which Philadelphia is the unquestioned leader,” said Saul Behar, senior VP of advancement and strategic initiatives at the University City Science Center, the West Philly research park where Spark began and grew its operations. “[This] further validates Greater Philadelphia’s status as a biotech hub with a very bright future.”
Spark CEO Jeff Marrazzo said the deep pool of resources from Roche, the company plans to “accelerate the development of more gene therapies for more patients for more diseases and further expedite our vision of a world where no life is limited by genetic disease.”
