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

"Throughout 2024, we made substantial progress across multiple fronts, advancing our programs, expanding collaborations, and strengthening our balance sheet to support significant anticipated milestones," stated Brian M. Culley, Lineage's CEO. "Our lead asset OpRegen continues to make progress in the ongoing GAlette Study, and we are encouraged by Roche and Genentech's commitment to the OpRegen program. Our partner's efforts to advance OpRegen for the treatment of dry AMD with GA include adding clinical sites and seeking and obtaining RMAT designation. We view these actions as positive indicators for this pioneering cell transplant and look forward to further updates on the program."

"We anticipate our internal programs will similarly advance through important milestones during 2025," added Mr. Culley. "We will focus on conducting the recently-initiated DOSED clinical study of a novel OPC1 delivery system, advancing ReSonance for the treatment of sensorineural hearing loss, and advancing other carefully selected early-stage initiatives. In parallel, we will continue our efforts to demonstrate an in-house manufacturing capability that supports Lineage having an industry-leading position in allogeneic cell banking and production. As the power of our cell differentiation and manufacturing platforms are further demonstrated and validated, we believe that our pipeline of internally-owned assets and cell-based know-how will make us a desirable development partner and an attractive opportunity for investors."

Fourth Quarter Operating Results

Revenues: Revenue is generated primarily from collaboration revenues, royalties, and other revenues. Total revenues for the three months ended December 31, 2024 were approximately $2.9 million, a net increase of $0.8 million as compared to $2.1 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 December 31, 2024 were $7.8 million, a decrease of $0.4 million as compared to $8.2 million for the same period in 2023.

R&D Expenses: R&D expenses for the three months ended December 31, 2024 were $3.4 million, a decrease of $0.5 million as compared to $3.9 million for the same period in 2023. The net decrease was primarily driven by $1.2 million for our OPC1 program expenses and $0.2 million for other research and development expense programs, partially offset by $0.4 million for our OpRegen program expenses and $0.5 million for our preclinical programs.

G&A Expenses: G&A expenses for the three months ended December 31, 2024 of $4.4 million were primarily in line with expenses for the same period in 2023.

Loss from Operations: Loss from operations for the three months ended December 31, 2024 was $5.1 million, a decrease of $1.3 million as compared to $6.4 million for the same period in 2023.

Other Income/(Expenses): Other income/(expenses) for the three months ended December 31, 2024 reflected other income of $1.8 million, compared to other income of $1.6 million for the same period in 2023. The net increase was primarily driven by changes in fair value of warrant liability, largely offset by exchange rate fluctuations related to Lineage's international subsidiaries and certain warrant-related transaction costs incurred as part of the November 2024 financing.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended December 31, 2024 was $3.3 million, or $0.02 per share (basic and diluted), compared to a net loss of $4.8 million, or $0.03 per share (basic and diluted), for the same period in 2023.

Full Year Operating Results

Revenues: Revenue is generated primarily from collaboration revenues, royalties, and other revenues. Total revenues for the year ended December 31, 2024 were $9.5 million, a net increase of $0.6 million as compared to $8.9 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 R&D expenses and G&A expenses. Total operating expenses for the year ended December 31, 2024 were $31.0 million, a decrease of $2.7 million as compared to $33.7 million for the same period in 2023.

R&D Expenses: R&D expenses for the year ended December 31, 2024 were $12.5 million, a decrease of $3.2 million as compared to $15.7 million for the same period in 2023. The decrease was primarily driven by $2.7 million for our OPC1 program expenses, $1.1 million for our preclinical and other research and development programs. These decreases were partially offset by $0.6 million for our OpRegen program.

G&A Expenses: G&A expenses for the year ended December 31, 2024 were $18.2 million, an increase of approximately $0.9 million as compared to $17.3 million for the same period in 2023. The net increase was primarily driven by $0.6 million for stock-based compensation expense and $0.4 million for personnel costs, partially offset by an overall decrease in costs incurred for services provided by third parties.

Loss from Operations: Loss from operations for the year ended December 31, 2024 was $21.5 million, a decrease of $3.2 million as compared to $24.7 million for the same period in 2023.

Other Income/(Expenses): Other income (expenses) for the year ended December 31, 2024 reflected other income of $2.9 million, compared to other income of $1.5 million for the same period in 2023. The net increase of $1.4 million was primarily driven by changes in the fair value of warrant liability, exchange rate fluctuations related to Lineage's international subsidiaries, and fair market value changes in marketable equity securities. This increase in other income was partially offset by certain warrant-related transaction costs incurred as part of the November 2024 financing, as well as the non-recurring prior year employee retention credit.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the year ended December 31, 2024 was $18.6 million, or $0.09 per share (basic and diluted), compared to a net loss of $21.5 million, or $0.12 per share (basic and diluted), for 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 under a gene editing partnership.
