Second Quarter 2025 Financial Results

Revenue for the second quarter of 2025 was $3.9 million, compared with $7.6 million for the same period in 2024. License and milestone revenue decreased primarily due to a $1.8 million decline in milestone revenue. Service revenue declined primarily due to the discontinuation of a small-molecule ion channel program and the related acceleration of non-cash revenue in the prior year period. These decreases were offset by $0.6 million in xPloration revenue as a result of the sale of an instrument and related consumables.

Cost of xPloration revenue was $0.3 million for the second quarter of 2025 and consists of direct costs associated with the sale of the xPloration instrument and associated consumables. Research and development expense was $10.9 million for the second quarter of 2025, compared with $13.9 million for the same period in 2024, with the decrease primarily due to lower share-based compensation expense and reduced headcount, and lower external expenses associated with the small-molecule ion channel programs. General and administrative expense was $7.7 million for the second quarter of 2025, compared with $8.0 million for the same period in 2024, with the decrease primarily due to lower legal fees and share-based compensation expense. Other operating income, net was $1.9 million, which included a gain of $3.0 million from the sale of a small molecule program to Angelini Pharma partially offset by a $1.0 million contingent liability adjustment associated with that program. Other operating income, net for the prior-year period was $2.5 million, which included a $2.6 million reduction in contingent liabilities attributed to changes in partner small molecule ion channel programs.

Net loss for the second quarter of 2025 was $15.9 million, or $0.15 per share, compared with a net loss of $13.6 million, or $0.13 per share, for the same period in 2024.

Cash use in the second quarter of 2025 was $2.0 million.

Year-to-Date Financial Results

Revenue for the first half of 2025 was $8.1 million, compared with $11.4 million for the same period in 2024. License and milestone revenue decreased primarily due to a $0.8 million decline in milestone revenue, partially offset by a $0.2 million increase in license revenue. Service revenue declined primarily due to the discontinuation of a small-molecule ion channel program and the related acceleration of non-cash revenue in the prior year period. These decreases were offset by $0.7 million in xPloration revenue as a result of the sale of an instrument and related consumables.

Cost of xPloration revenue was $0.3 million for the first half of 2025 and consists of direct costs associated with the sale of the xPloration instrument and associated consumables. Research and development expense was $23.5 million for the first half of 2025, compared with $28.5 million for the same period in 2024, primarily due to lower share-based compensation expense and reduced headcount, and lower external expenses associated with the small-molecule ion channel programs and screening technology development. General and administrative expense was $15.6 million for the first half of 2025, compared with $16.3 million for the same period in 2024 with the decrease primarily due to lower legal fees and share-based compensation expense. Other operating income, net for the first half of 2025 reflected a gain of $3.0 million from the sale of a small molecule program to Angelini Pharma, partially offset by a $1.0 million contingent liability adjustment associated with that program, whereas the prior-year period included a $2.6 million reduction in contingent liabilities attributed to changes in partner small molecule ion channel programs.

Net loss for the first half of 2025 was $34.1 million, or $0.32 per share, compared with a net loss of $32.6 million, or $0.32 per share, for the same period in 2024.

As of June 30, 2025, OmniAb had cash, cash equivalents and short-term investments of $41.6 million.

2025 Financial Guidance

OmniAb affirms guidance for 2025 revenue to be in the range of $20 million to $25 million, and for costs and operating expense to be in the range of $85 million to $90 million. In addition, OmniAb continues to expect 2025 cash use to be lower than cash use in 2024. Cash use in 2024 was $38.9 million, excluding the 2024 ATM issuance.

Business and partner highlights from the second quarter of 2025 and recent weeks included the following:

xPloration^®

• In May, OmniAb launched the xPloration Partner Access Program. xPloration is a high-throughput single B-cell screening instrument that leverages machine learning and artificial intelligence to address challenges in primary B-cell screening with traditional methods. xPloration’s competitive edge includes unmatched screening throughput, superior hit recovery, exceptional ease-of-use and reliability.

• OmniAb highlighted case studies utilizing xPloration in a presentation titled “xPloration: Simplifying Deep Antibody Mining for Maximum Impact” at the 21^st Annual PEGS Boston Conference and Expo, where xPloration was awarded 2025 Best of Show. The presentation illustrated the platform’s capabilities across various assay formats, including multiplex cell surface binding and cross-blocking assays.

IMVT-1402

• In May, Immunovant started recruitment of a randomized, placebo-controlled, double-blind Phase 3 study to assess the efficacy and safety of IMVT-1402 in patients with mild-to-severe generalized myasthenia gravis.

• Immunovant is also enrolling patients in potentially registrational trials of IMVT-1402 in chronic inflammatory demyelinating polyneuropathy, Graves’ disease, difficult-to-treat rheumatoid arthritis and Sjogren’s disease. Additionally, a proof-of-concept study has been initiated in a sixth indication, cutaneous lupus erythematosus.

TEV-53408

• Teva Pharmaceutical announced that the U.S. Food and Drug Administration (FDA) granted Fast Track designation for investigational TEV-53408, an anti-IL15 antibody, for the treatment of people with celiac disease on a gluten-free diet. TEV-53408 is currently being evaluated in Phase 2a and Phase 1 clinical trials to assess the efficacy and safety in adults with celiac disease and vitiligo, respectively.

TEV-56278

• Teva Pharmaceutical and Shanghai Fosun Pharmaceutical announced that the companies, through their respective subsidiaries, entered into a strategic partnership for the development of investigational TEV-56278, an anti-PD1-IL2 ATTENUKINE therapy. Teva's proprietary ATTENUKINE technology provides a new mechanism of action, potentially offering high efficacy and low toxicity in a broad array of oncology indications

JNJ-5322

• At the American Society of Clinical Oncology (ASCO) Annual Meeting, Johnson & Johnson presented initial Phase 1 results of JNJ-5322, a next-generation trispecific T-cell redirecting antibody targeting BCMA x GPRC5D x CD3, in patients with relapsed or refractory multiple myeloma. JNJ-5322 demonstrated a 100% overall response rate (ORR) at the recommended Phase 2 dose of 100 mg in anti-BCMA/-GPRC5D naïve patients, with convenient dosing every four weeks. Initial data with JNJ-5322 suggest a paradigm shift, offering ORRs similar to CAR-Ts but as an off-the-shelf therapy intended for outpatient dosing.

M9140

• At the ASCO Annual Meeting, Merck KGaA presented data on M9140, a novel antibody-drug conjugate with topoisomerase 1 inhibitor payload targeting tumors that express carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5). In the Phase 1 PROCEADE-CRC-01 study, M9140 showed a predictable, manageable safety profile and promising early clinical activity in heavily pretreated metastatic colorectal cancer (mCRC) patients. The ORR of 31% (17.2% confirmed) and median progression free survival (mPFS) of 6.9 months at 2.8 mg/kg every three weeks compares favorably with current monotherapy standard of care (ORRs 1-2%, mPFS 1.9-3.7 months) and recent Phase 3 data with trifluridine–tipiracil + bevacizumab (ORR 6.1%, mPFS 5.6 months) in 3L+ mCRC. These results suggest 2.8 mg/kg as the recommended Phase 2 dose for further development in colorectal cancer, and other solid tumors.

• Merck KGaA also presented the PROCEADE PanTumor Phase 1b/2 clinical trial study design at the American Association for Cancer Research Annual Meeting (AACR). This study will assess the antitumor activity, tolerability, safety and pharmacokinetics of M9140 either as monotherapy or in combination with other anticancer agents in patients with advanced/metastatic gastric cancer, non-small cell lung cancer (NSCLC) and pancreatic adenocarcinoma.

Sugemalimab

• CStone Pharmaceuticals announced the publication of long-term survival data from its Phase 3 GEMSTONE-302 trial in The Lancet Oncology. This study evaluates sugemalimab combined with platinum-based chemotherapy as a first-line treatment for both squamous and non-squamous, non-oncogene-addicted metastatic NSCLC. This marks the trial’s third publication in a top-tier journal, following earlier publications of final progression-free survival results in The Lancet Oncology (2022) and interim overall survival results in Nature Cancer (2023).

• CStone Pharmaceuticals also announced an exclusive partnership with Istituto Gentili, a European biopharmaceutical company with a century-long heritage in oncology, to commercialize sugemalimab across Western Europe and the UK. Under the agreement, Gentili received exclusive commercialization rights for sugemalimab in 23 European countries, as well as the UK and other geographies.

BC3195

• At the ASCO Annual Meeting, BioCity presented data on BC3195, a first-in-human antibody-drug conjugate targeting CDH3. BC3195 demonstrated a manageable safety profile and favorable pharmacokinetics, with impressive preliminary antitumor activity in heavily pretreated NSCLC patients – most of whom had EGFR mutations – achieving an ORR of 50%. Dose optimization and expansion are ongoing.
