"Our intent to separate our wholly owned biopharma programs from our royalty assets provides investors with the opportunity to realize and enhance the potential value of two distinct sets of assets. Jemperli sales grew to $785 million YTD with GSK indicating dMMR endometrial market share is now ~5% greater than Keytruda1, reflecting Jemperli’s differentiated overall survival data and supporting GSK’s peak sales guidance of far more than $2.7 billion2 in monotherapy indications," said Daniel Faga, president and chief executive officer of Anaptys. "Our biopharma portfolio is strategically positioned with multiple attractive, high-potential assets, including rosnilimab, ANB033 and ANB101. Rosnilimab’s transformational profile was highlighted in a late-breaking presentation of Phase 2b data in RA at ACR Convergence 2025 and we anticipate reporting top-line Phase 2 data through Week 12 in ulcerative colitis in November or December."
INTENT TO SEPARATE BUSINESS
Announced intent to separate biopharma operations from substantial royalty assets by YE 2026
Designed to unlock potential value by creating two independent, publicly traded companies with different business objectives and opportunities
The royalty management company will manage royalties and milestone payments from financial collaborations, including Jemperli with GSK and imsidolimab with Vanda, with a focus on protecting and returning their value to shareholders
The biopharma operations company will focus on development and potential commercialization of innovative immunology therapeutics for autoimmune and inflammatory diseases, including rosnilimab, ANB033 and ANB101
ROYALTY MANAGEMENT CO
GSK Jemperli Financial Collaboration
GSK announced strong commercial performance for Jemperli ($303 million/£230 million in Q3 2025 sales; $785 million/£600 million in YTD 2025 sales) with >16% USD and >17% GBP quarter-over-quarter growth1
In Q4 2025, Anaptys anticipates accruing a one-time $75 million commercial sales milestone from GSK once Jemperli achieves $1 billion in worldwide net sales
>$390 million in annualized Jemperli royalties payable to Anaptys at GSK’s peak sales guidance of >$2.7 billion2, which Anaptys expects to be achieved before 2031

Substantial GSK investment in additional monotherapy and potential combination trials for Jemperli including –
AZUR-1 – pivotal Phase 2 – dostarlimab monotherapy in untreated stage II/III dMMR/MSI-H locally advanced rectal cancer
Top-line data expected in H2 2026; U.S. FDA Breakthrough Therapy Designation
AZUR-2 – pivotal Phase 3 – dostarlimab versus standard of care in untreated TN40 or stage III dMMR/ MSI-H resectable colon cancer
AZUR-4 – Phase 2 – dostarlimab plus chemotherapy versus standard of care (chemotherapy) in untreated stage III MMRp/MSS resectable colon cancer
JADE – pivotal Phase 3 – dostarlimab monotherapy versus placebo in locally advanced unresected head and neck squamous cell carcinoma (PD-L1 high) post chemoradiation
Vanda Imsidolimab Financial Collaboration
Vanda anticipates FDA BLA submission for imsidolimab in generalized pustular psoriasis (GPP) in Q4 2025
BIOPHARMA CO
Rosnilimab (Pathogenic T Cell Depleter)
Presented Phase 2b data for rosnilimab, a pathogenic T cell depleter, in rheumatoid arthritis as a late-breaking oral presentation at American College of Rheumatology (ACR) Convergence 2025
In both the overall and b/tsDMARD-experienced populations, response rates across multiple higher-order endpoints, including ACR50, ACR70, CDAI LDA, CDAI remission, and patient-reported outcomes increased between Week 12 and Week 28 and are maintained off-drug for at least 3-months through Week 38
Regardless of prior therapy, including JAKs, similar responses were observed on more stringent endpoints, such as ACR50, ACR70, CDAI LDA and CDAI remission
Safety data through Week 38 demonstrate rosnilimab was well-tolerated, including no malignancies and no deaths
The presentation is available for download on the Anaptys website here
Top-line data through Week 12 of global Phase 2 trial in moderate-to-severe UC (N=136, ~50% advanced therapy experienced) on track for November/December 2025
Assessing Q2W and Q4W dose levels of subcutaneously administered rosnilimab vs. placebo (randomized 1:1:1)
Will report data on primary statistical analysis at Week 12 on well-established endpoints, including the primary endpoint of change from baseline in modified Mayo Score (mMS) and key secondary endpoints, such as clinical response and remission on mMS
All patients in all three study arms treat-through to Week 24 and remain blinded to treatment arm. Placebo-treated patients who achieved clinical response on partial mMS (pmMS) at Week 12 remain on placebo, while placebo-treated patients who are non-responders are crossed over to the high dose Q2W rosnilimab treatment arm
Patients who are in clinical response on pmMS at Week 24 are eligible for an additional 26-week (50 weeks of total treatment) blinded treatment extension period (TEP)
Blinded surveillance data to date suggest a favorable safety and tolerability profile consistent with prior rosnilimab trials
ANB033 (CD122 antagonist)
Hosted virtual investor event on ANB033 including preclinical and Phase 1a data

Third Quarter 2025 Financial Results
Cash, cash equivalents and investments totaled $256.7 million as of September 30, 2025, compared to $420.8 million as of December 31, 2024, for a decrease of $164.1 million due primarily to $113.9 million used for operating activities and $65.2 million in shares repurchased offset by $15 million upfront payment received from Vanda Pharmaceuticals for the license of imsidolimab.
Collaboration revenue was $76.3 million and $126.4 million for the three and nine months ended September 30, 2025, compared to $30.0 million and $48.2 million for the three and nine months ended September 30, 2024. The increase was due primarily to Jemperli total sales for 2025 exceeding $750 million which earned a $50 million commercial sales milestone in Q3 under the license agreement. Jemperli royalties increased 80% from $13.8 million to $24.9 million and 110% from $30.1 million to $63.2 million for the three and nine months ended September 30, 2025, and $9.7 million in revenue recognized for the Vanda license agreement.
Research and development expenses were $31.4 million and $110.4 million for the three and nine months ended September 30, 2025, compared to $42.2 million and $121.3 million for the three and nine months ended September 30, 2024. The decrease for the three and nine months ended September 30, 2025, was primarily due to lower development costs for ANB032 and imsidolimab, offset by higher costs relating to the Phase 1 trials for ANB033 and ANB101. The R&D non-cash, stock-based compensation expense was $4.5 million and $13.3 million for the three and nine months ended September 30, 2025, as compared to $4.0 million and $10.9 million in the same period in 2024.
General and administrative expenses were $10.2 million and $34.9 million for the three and nine months ended September 30, 2025, compared to $10.6 million and $32.2 million for the three and nine months ended September 30, 2024. The increase was due primarily to transaction costs associated with the Vanda Pharmaceuticals license agreement. The G&A non-cash, stock-based compensation expense was $4.7 million and $14.2 million for the three and nine months ended September 30, 2025, as compared to $4.2 million and $14.9 million in the same period in 2024.
Net income was $15.1 million for the three months ended September 30, 2025, or a net income per share of $0.54 and a net loss of $62.8 million for the nine months ended September 30, 2025, or a net loss per share of $2.16, compared to a net loss of $32.9 million and $123.4 million for the three and nine months ended September 30, 2024, or a net loss per share of $1.14 and $4.46.
