Financial Highlights

• Cash, cash equivalents, short-term and long-term investments totaled $62.9 million as of December 31, 2023.
• Selling, general, and administrative (SG&A) costs decreased versus the prior year, 16% for the twelve months ended December 31, 2023.

Full Year 2023 Financial Results Compared to Prior Year Period

Research and development expenses increased $1.4 million, or 3.1%, compared to year ended December 31, 2022. Salaries, benefits, and other personnel costs increased $2.8 million due to an increase in the hiring of employees to support the growth in the Company's development activities, and to a lesser extent, increases in salaries of our continuing employees. These increases were offset by less expenses incurred related to preclinical research programs for the comparable period.

SG&A expenses decreased $7.6 million, or 15.8%, compared to the year ended December 31, 2022. This decrease was primarily driven by a reduction in professional fees of $6.5 million, due to decreased legal fees associated with certain litigation matters, and $0.7 million decreased insurance-related premiums.

Total revenues decreased $20.7 million, or 76.9%, compared to the year ended December 31, 2022. Collaboration and licensing revenues decreased $14.6 million, or 99.5%, compared to the year ended December 31, 2022, primarily due to the prior year period non-cash recognition of revenue related to historical collaboration agreements for which revenue was previously deferred. Product and services revenues decreased $5.9 million, or 48.8%, compared to the year ended December 31, 2022. This decrease is related to reductions in services performed at Exemplar as well as the recognition of revenue in the first quarter of 2022 related to agreements for which revenue was previously deferred that did not occur in 2023.

Total other income, net, increased $8.5 million, compared to the year ended December 31, 2022. This was primarily due to $6.3 million in reduced interest expense associated with the Convertible Notes as they were fully retired in the second quarter of 2023, and $3.1 million increased interest income due to higher interest rates on investments. This increase was partially offset by a $0.9 million decrease in gain recorded on the early retirement of a portion of our Convertible Notes compared to the year ended December 31, 2022.

The Company recorded a $10.4 million impairment charge in the fourth quarter of 2023 related to its Exemplar subsidiary as a result of the Company's annual goodwill impairment test.

Loss from continuing operations was $95.9 million, or $(0.39) per basic and diluted share, compared to loss from continuing operations of $79.8 million, or $(0.40) per basic and diluted share, in year ended December 31, 2022.

UltraCAR-T^®
UltraCAR-T is a multigenic autologous CAR-T platform that utilizes Precigen's advanced non-viral Sleeping Beauty system to simultaneously express an antigen-specific CAR to specifically target tumor cells, mbIL15 for enhanced in vivo expansion and persistence, and a kill switch to conditionally eliminate CAR-T cells for a potentially improved safety profile. Precigen has advanced the UltraCAR-T platform to address the inhibitory tumor microenvironment by incorporating a novel mechanism for intrinsic checkpoint blockade without the need for complex and expensive gene editing techniques. UltraCAR-T investigational therapies are manufactured via Precigen's overnight manufacturing process using the proprietary UltraPorator^® electroporation system at the patient's medical center and administered to patients only one day following gene transfer. The overnight UltraCAR-T manufacturing process does not use viral vectors and does not require ex vivo activation and expansion of T cells, potentially addressing major limitations of current T cell therapies.

UltraCAR-T^® Clinical Program
Precigen's UltraCAR-T platform is currently under clinical investigation for hematological and solid tumors, including a Phase 1/1b study of PRGN-3005 UltraCAR-T in patients with advanced, recurrent platinum resistant ovarian, fallopian tube or primary peritoneal cancer (NCT03907527), a Phase 1/1b study of PRGN-3006 UltraCAR-T in patients with relapsed or refractory acute myeloid leukemia (AML) or higher risk myelodysplastic syndrome (MDS) (NCT03927261) and a Phase 1/1b study of PRGN-3007 UltraCAR-T incorporating PD-1 checkpoint inhibition in patients with ROR1-positive (ROR1⁺) chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma (DLBCL) and triple negative breast cancer (TNBC) (NCT05694364). PRGN-3006 UltraCAR-T has been granted Orphan Drug Designation and Fast Track Designation in patients with AML by the US Food and Drug Administration (FDA).

UltraCAR-T^® Library Approach
Precigen's UltraCAR-T library approach is designed to transform the personalized cell therapy landscape for cancer patients. Precigen's goal is to develop and validate a library of non-viral plasmids to target tumor-associated antigens. Enabled by design and manufacturing advantages of UltraCAR-T, coupled with the capabilities of the UltraPorator® system, Precigen is working to empower medical centers to deliver personalized, autologous UltraCAR-T treatment with overnight manufacturing to any cancer patient. Based on the patient's cancer indication and biomarker profile, one or more non-viral plasmids would be selected from the library to build a personalized UltraCAR-T treatment. After initial treatment, this approach has the potential to allow for redosing of UltraCAR-T targeting the same or new tumor-associated antigen(s) based on the treatment response and the changes in antigen expression of the patient's tumor. Precigen believes that the combination of the advanced UltraVector^® DNA construction platform and the ease of overnight manufacturing gives this library approach a proprietary advantage over traditional T-cell therapies.

UltraPorator^®
The UltraPorator system is an exclusive device and proprietary software solution for the scale-up of rapid and cost-effective manufacturing of UltraCAR-T therapies and potentially represents a major advancement over current electroporation devices by significantly reducing the processing time and contamination risk. The UltraPorator device is a high-throughput, semi-closed electroporation system for modifying T cells using Precigen's proprietary non-viral gene transfer technology. UltraPorator is being utilized for clinical manufacturing of Precigen's investigational UltraCAR-T therapies in compliance with current good manufacturing practices.

AdenoVerse^™ Immunotherapy
Precigen's AdenoVerse immunotherapy platform utilizes a library of proprietary adenovectors for the efficient gene delivery of therapeutic effectors, immunomodulators, and vaccine antigens designed to modulate the immune system. Precigen's gorilla adenovectors, part of the AdenoVerse library, have potentially superior performance characteristics as compared to current competition. AdenoVerse immunotherapies have been shown to generate high-level and durable antigen-specific T-cell immune responses as well as an ability to boost these responses via repeat administration. Superior performance characteristics and high yield manufacturing of AdenoVerse vectors leveraging UltraVector^® technology allows Precigen to engineer cutting-edge investigational gene therapies to treat complex diseases.

AdenoVerse^™ Immunotherapy Clinical Program
Precigen's AdenoVerse immunotherapy platform is currently under clinical investigation in a Phase 1/2 study of PRGN-2009 AdenoVerse immunotherapy alone or in combination with an anti-PDL1/TGF-Beta Trap in patients with HPV-associated cancers (NCT04432597), a Phase 2 study of PRGN-2009 in combination with pembrolizumab in newly diagnosed patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) (NCT05996523), a Phase 2 study of PRGN-2009 AdenoVerse immunotherapy in combination with pembrolizumab in patients with recurrent or metastatic cervical cancer (NCT06157151), and a Phase 1/2 study of PRGN-2012 AdenoVerse immunotherapy in patients with recurrent respiratory papillomatosis (RRP) (NCT04724980). PRGN-2012 has been granted Orphan Drug Designation and Breakthrough Therapy Designation in patients with RRP by the FDA and Orphan Drug Designation by the European Commission.
