Lineage Cell Therapeutics Reports Third Quarter 2024 Financial Results and Provides Business Update

• OpRegen^® Granted Regenerative Medicine Advanced Therapy (RMAT) Designation From FDA
• ReSonance™ (ANP1) Preclinical Results Presented at 59th Annual Inner Ear Biology Workshop
• Added to 2024 Russell 3000^® Index

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing allogeneic cell therapies for unmet medical needs, today reported its third quarter 2024 financial and operating results. The Company will host a conference call today at 4:30 p.m. Eastern Time to discuss these results and to provide a business update.

“We were delighted to see our partners’ continued commitment to the OpRegen program, in this instance by seeking and successfully obtaining RMAT designation,” stated Brian M. Culley, Lineage CEO. “We believe OpRegen continues to showcase itself as an asset with the potential to be ‘a transformational medicine’ and view the recent RMAT designation as additional positive progress for this pioneering cell transplant program. As we worked to return our second cell transplant program, OPC1 for spinal cord injury, back into the clinic, we also presented promising preclinical results from our third program, ReSonance, for sensorineural hearing loss. We look forward to continuing to create value through the advancement of our clinical and preclinical pipelines, applying both our technology and extensive manufacturing expertise to validate our cell transplant approach.”

Recent Operational Highlights

- RG6501 (OpRegen)

• Roche and Genentech, a member of the Roche Group, announced receipt of RMAT designation from the U.S. FDA for OpRegen, for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration (AMD).
• Continued execution under our collaboration with Roche and Genentech across multiple functional areas, including support for the ongoing Phase 2a clinical study (the “GAlette Study”) in patients with GA secondary to AMD.
• Continued activities under the separate services agreement with Genentech to support ongoing development of OpRegen. Lineage has been providing additional clinical, technical, training and manufacturing services funded by Genentech, that further support the ongoing advancement and optimization of the OpRegen program and include: (i) activities to support the ongoing Phase 1/2a study and currently-enrolling Phase 2a study; and (ii) additional technical training and materials related to Lineage’s cell therapy technology platform to support commercial manufacturing strategies.

- OPC1

• DOSED (Delivery of Oligodendrocyte Progenitor Cells for Spinal Cord Injury: Evaluation of a Novel Device) clinical study for the treatment of subacute and chronic spinal cord patient start-up activities and FDA interactions continue.

- ReSonance (ANP1)

• Preclinical results presented at 59^th Annual Inner Ear Biology Workshop
  • ReSonance manufactured by a proprietary process, developed in-house, at clinical scale, with relevant in-vitro functional activity
  • Immediate-use, thaw-and-inject formulation durably engrafted in multiple preclinical hearing loss models
  • ReSonance is currently being evaluated in a functional model of hearing loss through a collaboration with the University of Michigan Kresge Hearing Research Institute.

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities of $32.7 million as of September 30, 2024 is expected to support planned operations into Q1 2026.

Third Quarter Operating Results

Revenues: Revenue is generated primarily from collaboration revenues, royalties, and other revenues. Total revenues for the three months ended September 30, 2024 were $3.8 million, a net increase of approximately $2.5 million as compared to approximately $1.2 million for the same period in 2023. The increase was primarily driven by more collaboration revenue recognized from deferred revenues under the collaboration and license agreement with Roche.

Operating Expenses: Operating expenses are comprised of research and development (R&D) expenses and general and administrative (G&A) expenses. Total operating expenses for the three months ended September 30, 2024 were $7.6 million, a decrease of $0.3 million as compared to $7.9 million for the same period in 2023.

R&D Expenses: R&D expenses for the three months ended September 30, 2024 were $3.2 million, a net decrease of approximately $0.6 million as compared to $3.7 million for the same period in 2023. The net decrease was primarily driven by $0.6 million for our OPC1 program, $0.4 million for our preclinical programs, and partially offset by $0.5 million for our OpRegen program.

G&A Expenses: G&A expenses for the three months ended September 30, 2024 were $4.4 million, a net increase of $0.4 million as compared to $4.0 million for the same period in 2023. The net increase was primarily driven by $0.3 million for personnel costs and $0.1 million for stock-based compensation expense.

Loss from Operations: Loss from operations for the three months ended September 30, 2024 were $3.8 million, a decrease of $2.9 million as compared to $6.7 million for the same period in 2023.

Other Income/(Expenses): Other income (expenses) for the three months ended September 30, 2024 reflected other income of $0.8 million, compared to other expenses of approximately ($0.4) million for the same period in 2023. The change was primarily driven by exchange rate fluctuations related to our international subsidiaries.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended September 30, 2024 was $3.0 million, or $0.02 per share (basic and diluted), compared to a net loss attributable to Lineage of $7.1 million, or $0.04 per share (basic and diluted), for the same period in 2023.

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing novel, “off-the-shelf,” cell therapies to address unmet medical needs. Lineage’s programs are based on its proprietary cell-based technology platform and associated development and manufacturing capabilities. From this platform, Lineage designs, develops, manufactures, and tests specialized human cells with anatomical and physiological functions similar or identical to cells found naturally in the human body. These cells are created by applying directed differentiation protocols to established, well-characterized, and self-renewing pluripotent cell lines. These protocols generate cells with characteristics associated with specific and desired developmental lineages. Cells derived from such lineages are transplanted into patients in an effort to replace or support cells that are absent or dysfunctional due to degenerative disease, aging, or traumatic injury, and to restore or augment the patient’s functional activity. Lineage’s neuroscience focused pipeline currently includes: (i) OpRegen, a retinal pigment epithelial cell therapy in Phase 2a development under a worldwide collaboration with Roche and Genentech, a member of the Roche Group, for the treatment of geographic atrophy secondary to age-related macular degeneration; (ii) OPC1, an oligodendrocyte progenitor cell therapy in Phase 1/2a development for the treatment of spinal cord injuries; (iii) ReSonance (ANP1), an auditory neuronal progenitor cell therapy for the potential treatment of auditory neuropathy; (iv) PNC1, a photoreceptor neural cell therapy for the potential treatment of vision loss due to photoreceptor dysfunction or damage; and (v) RND1, a novel hypoimmune induced pluripotent stem cell line being developed in collaboration with Factor Bioscience Limited.
