Telesis Bio, a leading provider of DNA and mRNA synthesis solutions to accelerate therapeutic discovery with fast and flexible on-site automated foundries, today announced that it has entered into a convertible preferred stock purchase agreement (the Purchase Agreement) to sell shares of a new series of convertible preferred stock in a private placement. The financing was led by Novalis LifeSciences and Northpond Ventures and is expected to result in gross proceeds to the Company of up to approximately $21 million.

The Company's recently launched proprietary next-generation enzymatic synthesis platform, Gibson SOLA™, allows customers to take full control of their nucleic acid supply-chain, protect valuable IP, and maintain ownership of data and insights to feed new generations of AI drug discovery models. The Gibson SOLA reagent platform and comprehensive software suite allows customers to use standard automated liquid handling equipment to perform overnight synthesis of long, complex constructs necessary for biologics, vaccine and cell therapy research and development.

"Gibson SOLA is game-changing technology that delivers on our vision of true on-demand overnight synthesis, allowing researchers to accelerate their timelines and stop sharing proprietary data with external service providers," said Eric Esser, President and CEO of Telesis Bio, adding, "This financing gives us a strong balance sheet with no debt, and sufficient capital to reach cash-flow breakeven while continuing to serve existing customers and expanding adoption of this next-generation platform."

"Telesis Bio is a true innovator in the synthetic biology space and the only company offering a proven, scalable on-site synthesis solution. The platform, powered by Gibson SOLA technology, delivers tremendous customer value and we are excited by the future growth prospects for the company," said Paul Meister, Partner, Novalis LifeSciences.

Financing

The Purchase Agreement provides for the sale and issuance of convertible preferred stock in two closings (the initial tranche and the second tranche). The initial tranche included the sale and issuance of approximately $17 million in shares of convertible stock of which $8 million was tied to cash infusion, and $9 million related to conversion of outstanding debt into convertible stock. Subject to the determination of the Company's Board of Directors (the Board) to affect the second tranche closing on or before March 6, 2026, the second tranche is expected to include the sale and issuance of $4 million in shares of convertible preferred stock.

As a condition to the private placement, the holders of the Company's redeemable convertible preferred stock consented to convert such securities into common stock, and certain holders of warrants exercisable for the Company's securities consented to terminate such warrants, which were converted and terminated, as applicable, at the first tranche closing.

The securities issued and sold in the private placement have not been registered under the Securities Act of 1933, as amended (the Securities Act), or any state's securities laws, and are being issued and sold in reliance on Section 4(a)(2) of the Securities Act. The securities may not be offered or sold in the United States, except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act.

Gibson SOLA

DNA and mRNA are critical raw materials that power therapeutic research and molecular diagnostics, and demand for high-quality and increasingly complex nucleic acids is large and growing rapidly. Gibson SOLA allows researchers to break free from their complicated and unreliable external supply chain by allowing them to make DNA and mRNA in their own labs on standard liquid handling equipment, overnight, on-demand, reliably and with high-throughput.

Even better, customers keep their own proprietary data. With the rise of AI-powered drug discovery models, data from every step in the process from sequence to molecule is more important and valuable than ever. Gibson SOLA lets researchers gain insights that can be used to feed AI models instead of giving that valuable data away for free to external service providers.

The Gibson SOLA reagent platform and comprehensive software suite can be used to deploy automated on-site synthesis solutions for a wide variety of targets, molecules, and applications, from low- to high-throughput. Learn more about it here.
