DNA Script Raises $38.5 Million in Series B Financing

Oversubscribed round led by LSP will fund accelerated product development and commercial operations in the U.S.

PARIS, May 16, 2019 - DNA Script today announced an oversubscribed Series B fundraising of $38.5M led by LSP, one of Europe's largest and most experienced healthcare investment rms. Bpifrance, through its Large Venture fund, joined the round, alongside existing investors Illumina Ventures, M. Ventures, Sonnova Partners, Kurma Partners and Idinvest Partners. The proceeds will enable DNA Script to accelerate the development of the company's rst products based on its industry-leading enzymatic technology for de novo synthesis of nucleic acids. The company is prioritizing the recruitment of top talent in the U.S. for its product development and commercialization teams in preparation for product launch, as well as on expanding its Paris-based research team.

DNA Script's innovative technology provides affordable, rapid, high-quality production of important genomic experimental precursors, such as oligonucleotides. The technology overcomes many of the ineciencies of today's synthetic DNA production. It features a novel biochemical process for nucleic acids synthesis based on the use of highly ecient enzymes, thus enabling enhanced performance while minimizing the use of harsh chemicals. The product portfolio based on DNA Script's proprietary enzymatic synthesis platform will enable molecular biology researchers to accelerate their experiments — with the goal of moving from design to results within a day for a broad range of applications.

"In less than two years since our last nancing round, the DNA Script team has developed enzymatic synthesis technology at an incredibly fast pace and extended the company's lead in this exciting and quickly expanding sector. As we announced earlier this year at the AGBT General Meeting, DNA Script was the rst company to enzymatically synthesize a 200mer oligo de novo with an average coupling eciency that rivals the best organic chemical processes in use today. Our technology is now reliable enough for its rst commercial applications, which we believe will deliver the promise of same-day results to researchers everywhere, with DNA synthesis that can be completed in just a few hours," said Thomas Ybert, CEO and cofounder of DNA Script.

"We are thrilled to lead this round with participation of such a respected group of founders and investors. We see DNA Script as the clear leader in this nascent eld," said Joachim (JR) Rothe, Managing Partner at LSP and new member of DNA Script's board. "The progress made by DNA Script in only two years is amazing, and we believe the company will shift the current DNA synthesis paradigm, not only in the research market but also in the broader pharma business — for personalized therapies and diagnostics in particular."
