**OmniAb Reports First Quarter 2026 Financial Results and Business Highlights**

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

**EMERYVILLE, Calif. (May 7, 2026) – OmniAb, Inc. (NASDAQ: OABI)** today reported financial results for the three months ended March 31, 2026, provided operating and partner program updates, and increased 2026 financial guidance.

"OmniAb experienced strong momentum during the first quarter as multiple partnered programs advanced into later-stage clinical development, reinforcing the diversity and value of our portfolio. With a very strong start to the year, we are raising our 2026 revenue guidance," stated Matt Foehr, Chief Executive Officer of OmniAb. "Continued progression of partner programs highlights the value of our technology platform and positions our business well for the future. Our innovation efforts continue to differentiate our platform as demonstrated by the launch of OmniUltra<sup>™</sup> and our xPloration<sup>®</sup> partner access program."

**First Quarter 2026 Financial Results**

Revenue for the first quarter of 2026 was $14.4 million, compared with $4.2 million for the same period in 2025, with the increase primarily related to milestone revenue.

Research and development expense was $9.6 million for the first quarter of 2026, compared with $12.6 million for the same period in 2025, with the decrease due to lower personnel expense, share-based compensation expense, and external expenses associated with legacy small molecule ion channel programs. General and administrative expense was $6.6 million for the first quarter of 2026, compared with $7.9 million for the same period in 2025, with the decrease primarily due to lower personnel expense, share-based compensation expense, and legal fees.

Amortization of intangibles increased to $6.0 million for the first quarter of 2026, compared with $3.2 million for the same period in 2025, primarily due to a $2.9 million non-cash impairment related to the discontinuation of certain legacy small-molecule ion channel programs.

Total costs and operating expenses were $22.3 million for the first quarter of 2026, compared with $23.0 million for the same period in 2025. Cash costs and operating expenses were $12.3 million for the first quarter of 2026, compared with $14.7 million for the same period in 2025 (see note regarding "Use of Non-GAAP Financial Measure" below for further discussion of this non-GAAP measure).

Net loss for the first quarter of 2026 was $7.7 million, or $0.06 per share, compared with a net loss of $18.2 million, or $0.17 per share, for the same period in 2025.

**2026 Financial Guidance**

OmniAb revises 2026 financial guidance and now expects revenue to be in the range of $28 million to $33 million, versus $25 million to $30 million previously, and costs and operating expenses to be in the range of $83 million to $88 million, versus $80 million to $85 million previously. Cash costs and operating expenses remain unchanged and are 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 now expects to end the year with cash and cash equivalents in the range of $33 million to $38 million, versus $30 million to $35 million previously. The full-year 2026 effective tax rate is expected to be approximately 0%.

**First Quarter 2026 and Recent Business Highlights**

During the first quarter of 2026, OmniAb entered into a new license agreement with Florida State University. As of March 31, 2026, the Company had 107 active partners and 409 active programs, including 32 OmniAb-derived programs in clinical development or being commercialized.

Business and partner highlights from the first quarter of 2026 and recent weeks included the following:

<u>IMVT-1402 & batoclimab</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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. Topline data from the proof-of-concept trial with IMVT-1402 in cutaneous lupus erythematosus is also expected in the second half of this year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Potentially registrational studies with IMVT-1402 in Graves' disease (GD), myasthenia gravis (MG), chronic inflammatory demyelinating polyneuropathy and Sjögren's disease remain on track with topline data in GD and MG expected in 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Immunovant announced topline data from its two Phase 3 studies evaluating batoclimab as a treatment for active, moderate-to-severe thyroid eye disease and intends to review future plans for the development of batoclimab with its partner HanAll Biopharma Co. Immunovant remains focused on rapidly advancing the clinical development of IMVT-1402.

<u>TEV- '408</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Teva Pharmaceuticals announced a funding agreement with Royalty Pharma of up to $500 million to accelerate the clinical development of Teva's anti-IL-15 antibody TEV-'408 for vitiligo.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Topline results of the Phase 1b trial evaluating TEV-'408 for vitiligo are expected in the first half of this year. Topline results of the Phase 2a trial evaluating TEV-'408 for celiac disease are expected in the second half of this year.

<u>Precemtabart tocentecan (M9140)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At the American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium, pooled data on precemtabart tocentecan, a novel anti-CEACAM5 antibody-drug conjugate with a topoisomerase 1 inhibitor payload, from the PROCEADE-CRC-01 study in patients with metastatic colorectal cancer were presented that showed an objective response rate of 26.8% and median progression-free survival of 6.9 months. The overall safety profile was consistent with earlier data with no new or unexpected treatment-emergent adverse events.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Merck KGaA indicated that based on Phase 1 data, it plans to advance precemtabart tocentecan directly to Phase 3 trials in metastatic colorectal cancer, with study initiation anticipated in the second or third quarter of 2026.

**Partner Information**

The information in this press release regarding partnered products and programs comes from information publicly released by our partners.

**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 actual and 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 actual and projected non-GAAP cash costs and operating expenses, when viewed in conjunction with GAAP figures, provides investors with a more meaningful understanding of our 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 actual and projected GAAP costs and operating expenses and non-GAAP costs and operating expenses is provided later in this press release.
