AbCellera's third quarter of 2025 was a build-out quarter as its two lead Phase 1 programs, ABCL635 (NK3R antagonist for vasomotor symptoms) and ABCL575 (OX40-ligand antibody for atopic dermatitis), progressed to plan toward 2026 readouts and the company started activities at its new Vancouver clinical-manufacturing facility with platform investments substantially complete. The standout organizational move was hiring Dr. Sarah Noonberg, a veteran physician-scientist, as Chief Medical Officer to steer the maturing clinical pipeline, while SVP of Development Jeff Nickel stepped down. Financially the quarter reflected the deliberate shift to internal drug development: revenue slipped to about $9 million as partner research fees declined, R&D climbed about $14 million to roughly $55 million on ~$15 million of program-specific spend, and the net loss widened to about $57 million (-$0.19 per share). The company ended the quarter with roughly $520 million in cash and marketable securities and about $680 million in total available liquidity including committed government funding. Management reiterated that it remained on track to nominate a fourth development candidate by year-end and that the pivotal ABCL635 proof-of-concept data would come as a single disclosure around mid-2026, and it acknowledged that partner-initiated programs are progressing to the clinic more slowly than once expected.
Thank you. Hello, everyone. Thank you for joining us for AbCellera's third quarter 2025 earnings call. I'm Tryn Stimart, AbCellera's Chief Legal and Compliance Officer. Dr. Carl Hansen, AbCellera's President and CEO, and Andrew Booth, AbCellera's Chief Financial Officer, are also on today's call. During this call, we anticipate making projections and forward-looking statements based on our current expectations and in accordance with the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995. Our actual results could differ materially due to several factors outlined in our latest Form 10-K and subsequent Forms 10-Q and 8-K filed with the Securities and Exchange Commission. AbCellera is not obligated to update any forward-looking statements, whether due to new information, future events, or otherwise. Our presentation today, our earnings press release, and our SEC filings are available on our Investor Relations website.
The information we provide about our pipeline is intended for the investment community and is not promotional. As we transition to our prepared remarks, please note that all dollars referred to during the call are U.S. dollars. After our prepared remarks, we will open the lines for questions and answers. Now, I'll turn the call over to Carl.
Thanks, Tryn, and thank you, everyone, for joining us today. Last quarter, we completed our transition from a platform company to a clinical-stage biotech with the initiation of our phase I clinical trials for ABCL 635 and ABCL 575. Both trials are progressing to plan and remain on track for readouts next year. I'm pleased to report that this quarter, we have also started activities at our new clinical manufacturing facility, and we have substantially completed our platform investments. We ended the quarter with approximately $680 million in available liquidity to execute on our strategy, and as we close out the year, we are confident in achieving all our corporate priorities, including advancing at least one more development candidate into IND enabling studies. A highlight of this quarter was the appointment of Dr. Sarah Nunberg as Chief Medical Officer.
Sarah is a physician scientist with over 20 years of clinical drug development experience. She has a broad—pardon me—she has worked across a broad range of modalities and indications and has led programs through all stages of development, from discovery through to approval. You can expect Sarah to join future earnings calls to provide updates on our clinical pipeline. With Sarah taking the helm, Dr. Jeff Nickel will be stepping down as our SVP of Development. I'd like to thank Jeff for his leadership in building development as we transitioned from a platform company to a clinical-stage biotech. With that, I will hand it over to Andrew to discuss our financials. Andrew?
Thanks, Carl.
As Carl pointed out, AbCellera continues to be in a strong liquidity position with approximately $520 million in cash and cash equivalents and with roughly $160 million in available committed government funding to execute on our strategy. We are continuing to execute on our plans with a focus on internal programs and leveraging our CMC and GMP investments. Looking at our business metrics, in the third quarter, we started work on one additional partner-initiated program, which takes us to a cumulative total of 103 programs with downstream participation. With phase I trials for ABCL 635 and ABCL 575 underway, we maintained a cumulative total of molecules to have reached the clinic at 18, including both our own pipeline and those led by partners. As we have stated previously, we view the overall progress of molecules in the clinic as a potential source of near and mid-term revenue.
Downstream milestone fees and royalty payments in the longer term. Turning to revenue and expenses, revenue for the quarter was $9 million, predominantly from research fees relating to work on partnered programs. This compares to revenue of approximately $7 million in the same quarter of last year. With respect to research fee revenue, as we have mentioned in the past, we expect these to continue to trend lower as we increasingly focus on our internal pipeline. Our research and development expenses for the quarter were $55 million, approximately $14 million more than last year. This expense reflects the focus on investment in our internal and co-development programs. The increase over the recent run-rate expense levels in Q3 is largely due to specific investments of $15 million on two internal programs.
In sales and marketing, expenses for Q3 were just under $3 million, a small reduction relative to the same quarter of last year. In general administration, expenses were approximately $22 million, compared to roughly $19 million in Q3 of 2024. Included in these expenses are the ongoing expenses related to the defense of our intellectual property. Looking at earnings, we're reporting a net loss of roughly $57 million for the quarter, compared to a loss of about $51 million in the same quarter of last year. In terms of earnings per share, this result works out to a loss of $0.19 per share on a basic and diluted basis. Looking at cash flows, operating activities for the first nine months of 2025 used approximately $97 million in cash and equivalents. Excluding investments in marketable securities, investment activities amounted to $49 million year to date.
This is predominantly in property, plant, and equipment, driven by investments in establishing clinical manufacturing, which are now substantially complete as we had expected. The investments in PP&E were partially offset by government contributions. As a part of our Treasury strategy, we have $413 million invested in short-term marketable securities. Our investment activities for the quarter included a $62 million net divestment of these holdings. Altogether, we finished the quarter with $523 million of total cash, cash equivalents, and marketable securities. As a reminder, we have received commitments for funding for the advancement of our internal pipeline from the Government of Canada's Strategic Innovation Fund and the Government of British Columbia.
This available capital does not show up on our balance sheet, and with over $520 million in cash and equivalents and the unused portion of our secured government funding, we have approximately $680 million in available liquidity to execute on our strategy. In addition, we have available liquidity in our ownership of both Vancouver-based lab and office buildings, as well as our GMP manufacturing facility, both of which have been financed off of our balance sheet. The operating cash usage for the remainder of 2025 will continue to prioritize advancing our two lead programs through their phase I clinical studies and building a strong pre-clinical pipeline. With respect to our overall company expenditures, our capital needs are very manageable, and we continue to believe that we have sufficient liquidity to fund well beyond the next three years of increasing pipeline investments.
We will be happy to take your questions. Operator?
