EMERYVILLE, Calif. (March 30, 2023) – OmniAb, Inc. (NASDAQ: OABI) today reported financial results for the three and 12 months ended December 31, 2022, and provided operating and partner program updates.

“Following the closing of the spin-off and business combination transactions last November, OmniAb is well-positioned for continued growth by offering cutting-edge antibody discovery platforms and complementary technologies,” said Matt Foehr, Chief Executive Officer of OmniAb. “Leveraging a rich heritage of innovations designed to facilitate the discovery of novel therapeutics including those targeting ion channels and transporters, OmniAb is at the forefront of antibody discovery with the industry’s only four-species platform facilitating fully human and bispecific antibody discovery, supported by a highly dedicated staff and world-class scientific and business advisors.

"2022 was another terrific year for the business as we added a record-high 13 new partnerships and our partners continued to increase their number of programs. We are excited about the future as we leverage our highly scalable business model and invest in our technologies,” he added. “We are planning to introduce new technologies and innovations later this year as we serve current partners and add new ones, while enhancing our best-in-class technology stack."

On November 1, 2022, OmniAb completed a spin-off from Ligand Pharmaceuticals Incorporated (NASDAQ: LGND), resulting in OmniAb becoming an independent publicly traded company. Financial results prior to November 1, 2022, are presented on a carve-out basis derived from Ligand’s historical accounting records, as if OmniAb were an independent company.

Revenue for the fourth quarter of 2022 was $35.3 million, compared with $15.3 million for the same period in 2021, with the increase primarily attributable to the recognition of a $25.0 million milestone payment related to the first commercial sale of TECVAYLI™ (teclistamab) in the U.S. OmniAb expects to recognize a $10.0 million milestone payment related to the first commercial sale in the European Union (EU) in 2023.

Research and development expense was $12.9 million for the fourth quarter of 2022, compared with $11.0 million for the same period in 2021, with the increase primarily due to investments in facilities, headcount and technology innovation. General and administrative expense was $10.2 million for the fourth quarter of 2022, compared with $4.3 million for the same period in 2021, with the increase primarily due to higher headcount related to becoming an independent publicly traded company.

Net income for the fourth quarter of 2022 was $6.8 million, or $0.07 per diluted share, compared with a net loss of $3.1 million, or $0.04 per share, for the same period in 2021.

Revenue for 2022 was $59.1 million, compared with $34.7 million for 2021, with the increase attributable to the recognition of the $25.0 million TECVAYLI™ (teclistamab) milestone payment following the first commercial sale in the U.S. and royalty revenue from our partners' sales of zimberelimab and sugemalimab.

Research and development expense for 2022 was $48.4 million, compared with $39.2 million for 2021, with the increase primarily due to continued investments in facilities, headcount and technology innovation. General and administrative expense for 2022 was $24.9 million, compared with $16.9 million for 2021, with the increase primarily due to expenses associated with the spin-off and business combination, as well as headcount-related expenditures as we prepared to become an independent public company.

Net loss for 2022 was $22.3 million, or $0.26 per share, compared with a net loss of $27.0 million, or $0.33 per share, for 2021. Cash used to fund operating activities was $3.6 million for 2022.

As of December 31, 2022, OmniAb had cash, cash equivalents and short-term investments of $88.3 million. Subsequent to the close of the year, in January 2023 OmniAb received $35.0 million in milestone payments from Janssen related to TECVAYLI™ (teclistamab). The current cash, cash equivalents and short-term investments balance, along with the cash the Company generates from operations are expected to be sufficient to fund operations for the foreseeable future. The Company expects its 2023 year-end cash, cash equivalents and short-term investments balance to be slightly higher than year-end 2022.

In 2022, the company signed 13 new licenses, including one in the fourth quarter with the Wistar Institute. In addition, during the quarter three new programs entered the clinic: M9140 (Merck KGaA), an antibody-drug conjugate anti-CEACAM5 in advanced solid tumors; GEN1053 (Genmab/BioNTech), a hexabody anti-CD27 in malignant solid tumors; and JNJ-79635322 (Janssen), a trispecific in relapsed or refractory multiple myeloma. As of December 31, 2022, the company had 69 active partners with 26 OmniAb-derived programs in clinical development or being commercialized, and a total of 291 programs being pursued or commercialized.

During the quarter, OmniAb entered into an agreement with mAbsolve Ltd. for STR, mAbsolve’s Fc-silencing platform technology. The agreement provides OmniAb with exclusive, sublicensable right to incorporate the STR technology with antibodies that have been generated using OmniAb’s antibody discovery platform.

Fourth quarter 2022 and recent partner highlights include the following:

TECVAYLI™ (teclistamab)

•Janssen Biotech, Inc. received approval from the U.S. Food and Drug Administration for TECVAYLI™ (teclistamab) for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy.

Batoclimab

•Immunovant announced initiation of a Phase 3 clinical trial of batoclimab in thyroid eye disease and a Phase 2b clinical trial in chronic inflammatory demyelinating polyneuropathy.

Sugemalimab

•EQRx announced the Marketing Authorization Applications for sugemalimab in combination with chemotherapy for the first-line treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) were accepted for review by both the Medicines and Healthcare products Regulatory Agency in the United Kingdom and the European Medicines Agency for the EU.

•CStone announced the National Medical Products Administration of China accepted the supplemental new drug application (sNDA) for sugemalimab in combination with chemotherapy as a first-line treatment of unresectable locally advanced or metastatic gastric/gastroesophageal junction adenocarcinoma. The sNDA is based on the GEMSTONE-303 study, in which sugemalimab in combination with chemotherapy as a first-line treatment for unresectable locally advanced or metastatic gastric adenocarcinoma/gastro-esophageal junction adenocarcinoma with PD-L1 expression ≥5% met one of its primary endpoints, progression-free survival. CStone also announced topline results from the GEMSTONE-304 study, in which sugemalimab in combination with chemotherapy as a first-line treatment of unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma met its primary endpoints.

Zimberelimab

About OmniAb®

OmniAb, Inc.’s discovery platform provides pharmaceutical industry partners access to diverse antibody repertoires and high-throughput screening technologies to enable discovery of next-generation therapeutics.

At the heart of the OmniAb platform is the Biological Intelligence™ (BI) of our proprietary transgenic animals, including OmniRat®, OmniChicken® and OmniMouse® that have been genetically modified to generate antibodies with human sequences to facilitate development of human therapeutic candidates. OmniFlic® (transgenic rat) and OmniClic® (transgenic chicken) address industry needs for bispecific antibody applications though a common light chain approach, and OmniTaur™ features unique structural attributes of cow antibodies for complex targets. We believe the OmniAb animals comprise the most diverse host systems available in the industry and they are optimally leveraged through computational antigen design and immunization methods, paired with high-throughput single B cell phenotypic screening and mining of next-generation sequencing datasets with custom algorithms to identify fully human antibodies with superior performance and developability characteristics. An established core competency focused on ion channels and transporters further differentiates our technology and creates opportunities in emerging target classes. OmniAb antibodies have been leveraged across modalities, including bispecific antibodies, antibody-drug conjugates and others.
