Our customers typically negotiate the terms of those licenses during research and preclinical development. We refer to these arrangements as SPL partnerships, the terms of which contain not only higher annual, non-exclusive fees for the clinical use of the instrument, but also allow us to share in the economics of the customer’s programs.

Our future milestone revenue under our SPL partnerships will depend in large part on the clinical and regulatory achievements of our customers. Generally, precommercial milestone payments become larger as programs move through clinical development. We rely in part on our customers’ public disclosures around regulatory timelines to forecast our receipt of precommercial milestone payments.

In addition, as customers use instruments they have either purchased or included with their license, they typically replenish their supplies of PAs and consumables through recurring purchases.
The amount of each milestone payment is typically correlated in size with value-creating, precommercial clinical progress events or commercial sales levels. Of the over 160 programs associated with our current SPLs, one is in commercial stage, and 16 of those programs are currently active in clinical development, meaning they have at least an FDA-cleared IND application or foreign equivalent.

This license fee varies based on whether the instrument is being used for preclinical or clinical purposes. Once we have leased an instrument to a customer, we generally have high visibility into future lease revenue from this customer.

For any of these reasons, a customer could determine not to renew or to enter into additional instrument leases with us, which could result in our actual future lease revenues differing from our estimates and projections. Our installed base of electroporation instruments has grown to over 680 instruments as of December 31, 2023.
For any of these reasons, a customer could determine not to renew or to enter into additional licenses with us, which could result in our actual future license revenues differing from our estimates and projections.

However, our actual milestone revenue from these agreements will likely be considerably lower than this amount, as not all programs covered by each agreement will become and remain active programs in a 77 Table of Contents customer’s development pipeline or successfully complete the clinical development process.

To date, we have funded our operations primarily with proceeds from sales of common stock, borrowings under loan agreements and cash flows associated with sales and licenses of our products to customers. On August 3, 2021, we completed our U.S. IPO, generating gross proceeds of $201.8 million.
As of December 31, 2024, we had an accumulated deficit of $216.9 million.
