Rhea-AI Filing Summary

OmniAb, Inc. reported weaker 2025 results but outlined growth plans and tighter cost control. Full-year 2025 revenue was $18.7 million, down from $26.4 million in 2024, mainly due to lower license, milestone and service revenue, partly offset by new xPloration and higher royalty revenue. The company posted a 2025 net loss of $64.8 million, or $0.57 per share, slightly higher than the prior year’s $62.0 million loss.

Research and development expense fell to $47.8 million and general and administrative expense to $29.2 million, helped by lower headcount, share-based compensation and legacy ion channel spending, though results included a $3.9 million impairment. OmniAb ended 2025 with $54.0 million in cash, cash equivalents and short-term investments.

For 2026, OmniAb guides to $25–$30 million in revenue and $80–$85 million in GAAP costs and operating expenses, with non‑GAAP cash costs of $50–$55 million, and expects year-end cash of $30–$35 million and an effective tax rate of approximately 0%. The company highlights 107 active partners, 407 active programs, the launch of its OmniUltra transgenic chicken platform, and multiple partner programs progressing through clinical development.

Insights

Revenue declined but guidance, pipeline breadth and cost discipline frame a stabilizing story.

OmniAb’s 2025 revenue dropped to $18.7 million from $26.4 million, reflecting fewer license, milestone and service revenues as legacy ion channel work tapered. Despite this, the company expanded to 107 active partners and 407 active programs, including 32 in clinical or commercial stages.

Operating structure is shifting toward a leaner model. Research and development fell to $47.8 million and general and administrative to $29.2 million, although results included a $3.9 million impairment. Ending cash of $54.0 million and a 2026 non‑GAAP cash cost target of $50–$55 million imply a continued cash burn that narrows if revenue reaches the guided $25–$30 million range.

Guidance for year-end 2026 cash of $30–$35 million and an effective tax rate near 0% suggests management expects ongoing losses but manageable liquidity through at least 2026. Progress of partner programs like IMVT‑1402, batoclimab, TEV‑'408 and precemtabart tocentecan, along with uptake of OmniUltra and xPloration, will be key drivers of future milestone and royalty revenue as disclosed timelines into 2027 unfold.

OmniAb Reports Fourth Quarter and Full Year 2025 Financial Results and Business Highlights
Conference Call Begins at 4:30 p.m. Eastern Time Today

EMERYVILLE, Calif. (March 4, 2026) – OmniAb, Inc. (NASDAQ: OABI) today reported financial results for the quarter and year ended December 31, 2025, and provided operating and partner program updates.

“OmniAb exited 2025 with an expanded base of 107 active partners and a growing portfolio of 407 active programs. Our differentiated technologies support our business outlook and allow us to add programs while maintaining a disciplined cost structure. As our partner pipeline continues to advance, several later-stage assets are emerging with potential to generate meaningful milestones and, ultimately, recurring royalty revenue,” said Matt Foehr, Chief Executive Officer of OmniAb. "Our focus on innovation was evident in the recent launch of OmniUltra, which strengthens our ability to attract new partners and service new programs. Additionally, we continue to see strong interest in the xPloration partner access program and are excited about its contributions to the business.”

Fourth Quarter 2025 Financial Results

Revenue for the fourth quarter of 2025 was $8.4 million, compared with $10.8 million for the same period in 2024, with the decrease primarily related to a decline in license revenue and service revenue, partially offset by an increase in milestone and royalty revenue and the addition of xPloration revenue.

Research and development expense was $13.9 million for the fourth quarter of 2025, compared with $13.3 million for the same period in 2024, with the increase due to a $3.9 million impairment charge primarily related to certain small molecule ion channel property and equipment, partially offset by lower personnel expenses related to reduced headcount and share-based compensation expense, and lower external expenses associated with legacy small molecule ion channel programs. General and administrative expense was $6.8 million for the fourth quarter of 2025, compared with $7.4 million for the same period in 2024, with the decrease primarily due to lower share-based compensation expense.

Net loss for the fourth quarter of 2025 was $14.2 million, or $0.11 per share, compared with a net loss of $13.1 million, or $0.12 per share, for the same period in 2024.

Full Year 2025 Financial Results

Revenue for 2025 was $18.7 million, compared with $26.4 million for 2024. The decline was primarily due to a decrease in license revenue of $2.5 million and milestone revenue of $1.6 million. Service revenue declined as a result of the completion or discontinuation of certain legacy small molecule ion channel programs. These decreases were offset by the addition of $0.8 million in xPloration revenue reflecting the sale of an instrument and related consumables.

Cost of xPloration revenue was $0.3 million for 2025 and consisted of direct costs associated with the sale of the xPloration instrument and associated consumables. Research and development expense was







$47.8 million for 2025, compared with $55.1 million for 2024, primarily due to lower personnel expenses related to reduced headcount and share-based compensation expense, lower external expenses associated with legacy small molecule ion channel programs and a decline in contract research costs, partially offset by a $3.9 million impairment charge primarily related to certain small molecule ion channel property and equipment. General and administrative expense was $29.2 million for 2025, compared with $30.7 million for 2024 with the decrease primarily due to lower legal fees and share-based compensation expense. Other operating income, net for 2025 was $2.5 million and reflected a gain of $3.0 million from the sale of a small molecule Kv7.2 program partially offset by a $0.3 million increase in contingent liability expense attributed to changes in certain ion channel programs. Other operating income, net during 2024 was $2.4 million and included a $2.5 million reduction in contingent liabilities primarily attributed to changes in small molecule ion channel programs.

Net loss for 2025 was $64.8 million, or $0.57 per share, compared with a net loss of $62.0 million, or $0.61 per share, for the same period in 2024.

As of December 31, 2025, OmniAb had cash, cash equivalents and short-term investments of $54.0 million.

2026 Financial Guidance

OmniAb expects 2026 revenue to be in the range of $25 million to $30 million, and costs and operating expenses to be in the range of $80 million to $85 million. Cash costs and operating expenses is expected to be in the range of $50 million to $55 million (see note regarding "Use of Non-GAAP Financial Measure" below for further discussion of this non-GAAP measure). The Company expects to end the year with cash and cash equivalents in the range of $30 million to $35 million. The 2026 effective tax rate is expected to be approximately 0%.

Fourth Quarter 2025 and Recent Business Highlights

During the fourth quarter of 2025, OmniAb entered into new license agreements including with Dana Farber Cancer Institute, Mabtrx Biosciences and two global pharmaceutical companies. As of December 31, 2025, the Company had 107 active partners and 407 active programs, including 32 OmniAb-derived programs in clinical development or being commercialized.

In December 2025, the Company launched OmniUltra™, the industry’s first and only transgenic chicken engineered to express ultralong CDRH3 domains on a human antibody framework. OmniUltra also enables the isolation of picobodies™, the smallest known natural antibody-derived binding domain (4–6 kDa), which are approximately one-third the size of a nanobody®. OmniUltra is designed to deliver pre-optimized specificity, affinity and structural stability, streamlining hit-to-lead identification. By generating both antibodies and picobodies, it is ideal for applications such as bispecifics, multispecifics, CAR-T, radioligands and stand-alone peptide therapeutics.

OmniAb and GSK published a paper titled “Voltage sensor interaction site for a selective small molecule Nav1.1 sodium channel potentiator that enhances firing of fast-spiking interneurons” in the October 2025 edition of Molecular Pharmacology. The paper highlights the potential for Nav1.1 as a therapeutic target for seizure disorders.








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

IMVT-1402 & batoclimab

The potentially registrational trial with IMVT-1402 in difficult-to-treat rheumatoid arthritis is fully enrolled, with topline data expected in the second half of this year.

Note Regarding Use of Non-GAAP Financial Measure

This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also projected cash costs and operating expenses, which is a non-GAAP financial measure, adjusted to exclude share-based compensation, depreciation and amortization of intangibles. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, OmniAb believes the presentation of projected non-GAAP cash costs and operating expenses, when viewed in conjunction with GAAP figures, provides investors with a more meaningful understanding of future operating performance. Cash costs and operating expense is not intended to be considered in isolation or as a substitute for costs and operating expenses. A reconciliation between projected cash costs and operating expenses and projected GAAP costs and operating expenses is provided later in this press release.
