OmniAb Reports First Quarter 2025 Financial Results and Business Highlights

Conference Call with Slides Begins at 4:30 p.m. Eastern Time Today

OmniAb, Inc. (NASDAQ:OABI) today reported financial results for the three months ended March 31, 2025, and provided operating and partner program updates.

"We have started the year with robust deal flow, including both platform and asset-based deals. Our business remains strong as our diversified pipeline of partner programs is progressing with recent and expected new clinical entrants and data readouts," said Matt Foehr, Chief Executive Officer of OmniAb. "Today we announced the xPloration® Partner Access Program for OmniAb partners, enhancing the scalability of our technology platforms and creating new business opportunities that we believe will be accretive to both earnings and cash flow in short- and long-term. This initiative furthers our mission to push the frontiers of discovery technologies along with our focus on creating value for our partners and our stakeholders. As we look ahead, our 2025 outlook remains on track with our commitment to running an efficient and leverageable business."

First Quarter 2025 Financial Results

Revenue for the first quarter of 2025 was $4.2 million, compared with $3.8 million for the same period in 2024, with the increase primarily due to the recognition of a $1.0 million Phase 1 milestone payment and higher license fees, partially offset by lower service revenue.

Research and development expense was $12.6 million for the first quarter of 2025, compared with $14.6 million for the same period in 2024, with the decrease primarily due to lower share-based compensation expense and lower external expenses associated with our small-molecule ion channel programs and technology development. General and administrative expense was $7.9 million for the first quarter of 2025, compared with $8.3 million for the same period in 2024, with the decrease primarily due to lower legal fees and share-based compensation expense.

Net loss for the first quarter of 2025 was $18.2 million, or $0.17 per share, compared with a net loss of $19.0 million, or $0.19 per share, for the same period in 2024.

As of March 31, 2025, OmniAb had cash, cash equivalents and short-term investments of $43.6 million.

2025 Financial Guidance

OmniAb affirms guidance for 2025 revenue to be in the range of $20 million to $25 million, and revises operating expense guidance to be in the range of $85 million to $90 million from the previous range of $90 million to $95 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. The 2025 full year effective tax rate is expected to be approximately 0%.

First Quarter 2025 and Recent Business Highlights

During the first quarter of 2025, OmniAb entered into three new platform license agreements including the Wyss Institute at Harvard University, Takis Biotech S.r.l. and Orion Corporation.

OmniAb entered into a research collaboration and license agreement with Orion Corporation to discover and generate an antibody-based compound for a specific ion-channel target. Under the terms of the agreement, OmniAb will receive an upfront payment of $250,000 and is eligible to receive service payments. OmniAb is also eligible to receive development, regulatory and commercialization milestone payments totaling to over $55 million. OmniAb will receive low- to mid-single digit tiered royalties on net sales, should the program reach commercialization.

As of March 31, 2025, the Company had 95 active partners and 378 active programs, including 33 OmniAb-derived programs in clinical development or being commercialized.

Post-quarter close, OmniAb entered into an asset-based sale with Angelini Pharma for a small molecule Kv7.2 program. OmniAb will receive an upfront payment of $3 million, and potential milestones of over $170 million and royalties.

In addition, OmniAb launched the offering of xPloration to existing partners through a 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, such as limited antibody diversity and lengthy processes. We believe it offers a competitive edge over current market offerings for B-cell screening with unmatched screening throughput, superior hit recovery, exceptional ease-of-use and reliability. OmniAb will showcase xPloration at the 21^st Annual PEGS Boston Summit, taking place May 12-16 at the Omni Boston Hotel at the Seaport.

First quarter 2025 and recent partner and business highlights include the following:

IMVT-1402

• Immunovant announced that potentially registrational trials for IMVT-1402 are currently enrolling patients in four indications: myasthenia gravis (MG), chronic inflammatory demyelinating polyneuropathy (CIDP), Graves' disease (GD) and difficult-to-treat rheumatoid arthritis.
• A fifth potentially registrational trial for Sjogren's disease is planned to begin in the summer of 2025. Additionally, a proof-of-concept study has been initiated in a sixth indication, cutaneous lupus erythematosus.

Batoclimab

• Immunovant announced positive study results for batoclimab in MG and CIDP. The pivotal study in MG met its primary endpoint, showing a change from baseline in the Myasthenia Gravis Activities of Daily Living score in the acetylcholine receptor antibody positive population at 12 weeks. The 680mg dose arm showed a 5.6-point improvement with a 74% mean immunoglobulin G (IgG) reduction, while the 340mg dose arm showed a 4.7-point improvement with a 64% mean IgG reduction.
• Initial CIDP results from Period 1, following standard-of-care washout, demonstrated a mean improvement in the adjusted Inflammatory Neuropathy Cause and Treatment (aINCAT) disability score of 1.8 across study arms. An 84% responder rate (with response defined as an aINCAT improvement ≥1) was observed among all patients whose IgG was reduced by ≥70%.
• In both batoclimab studies, deeper IgG reductions correlated with better clinical outcomes across a range of assessments and timepoints.
• Immunovant expects to announce additional data for batoclimab in GD, including six-month remission data, this summer. Additionally, top-line results for batoclimab from potentially registrational Phase 3 trials in thyroid eye disease are expected in the second half of 2025.

Sugemalimab

• CStone Pharmaceuticals announced the submission of a Type II variation application to the European Medicines Agency (EMA) for sugemalimab, seeking approval for the treatment of unresectable stage III non-small cell lung cancer (NSCLC) in patients who have not progressed following platinum-based chemoradiotherapy. This is CStone's second regulatory submission for sugemalimab to the EMA, following its 2024 approval for metastatic NSCLC.

TEV-53408

• Teva Pharmaceuticals initiated a Phase 2 trial of TEV-53408 in adults with celiac disease. The primary efficacy objective is to assess the ability of TEV-53408 to attenuate gluten-induced enteropathy. Additional objectives include the safety assessment of TEV-53408.

RNDO- 564

• Rondo Therapeutics published preclinical data for RNDO-564, a CD28 x Nectin-4 bispecific antibody for bladder cancer, in the Journal of Immunotherapy of Cancer. In vitro studies demonstrated that RNDO-564 enhanced T-cell activation and cytotoxicity against Nectin-4 positive tumor cells. The antibody demonstrated significant tumor regression in tumor-bearing mouse models, both alone and with an immune checkpoint inhibitor. Favorable pharmacokinetic and tolerability profiles were observed in non-human primates.

OmniAb recently appointed Philip J. Gotwals, Ph.D., and Steve Crouse to its Board of Directors. Dr. Gotwals, with 30 years of biopharmaceutical experience in R&D, business development, product development, and therapeutic area strategy, along with Mr. Crouse, who brings over 20 years of expertise in life sciences sales and marketing, product development, business development, and general management, will help advance the Company's strategic initiatives.

OmniAb reported that partners presented data on nine OmniAb derived molecules at the American Association for Cancer Research Annual Meeting 2025, held April 25-30. These presentations showcased clinical trial designs, as well as data across various preclinical and clinical studies.

The Company also expects that multiple partners will be presenting data from programs developed with OmniAb technology at the American Society of Clinical Oncology Annual Meeting taking place May 30 - June 3, 2025.
