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 fourth quarter and full year 2023 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 2023, our team has continued to advance our clinical and preclinical pipeline of differentiated cell transplant programs,” stated Brian M. Culley, Lineage CEO. “The most important area of attention has remained our partnership with Roche and Genentech and the support we provide to the ongoing Phase 2a clinical study of OpRegen in patients with geographic atrophy secondary to AMD. With the recent clearance of our IND amendment for OPC1, we are excited for the opportunity to return this program back into the clinic in both subacute and, for the first time, chronic spinal cord injury patients. Following the closing of our recent financing, a transaction conducted without a discount or warrants, our balance sheet has been strengthened, which will help us advance our programs and reach important milestones this year that can help provide a meaningful impact for patients.”

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities of $35.5 million as of December 31, 2023, together with the approximate $13.8 million in net proceeds from the registered direct offering of our common shares completed in February 2024, is expected to support planned operations into Q3 2025.

Fourth Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from collaboration revenues and royalties. Total revenues for the three months ended December 31, 2023 were approximately $2.1 million, a net increase of $0.2 million as compared to $1.9 million for the same period in 2022.

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, 2023 were $8.2 million, a decrease of $0.3 million as compared to $8.5 million for the same period in 2022.

R&D Expenses: R&D expenses for the three months ended December 31, 2023 were $3.9 million, a decrease of $0.2 million as compared to $4.1 million for the same period in 2022. The net decrease was primarily driven by $0.2 million in OpRegen program expenses and $0.4 million for other research and development expense programs, partially offset by $0.2 million in OPC1 program expenses and $0.2 million for preclinical programs.

G&A Expenses: G&A expenses for the three months ended December 31, 2023 of $4.3 million were in line with expenses for the same period in 2022.

Loss from Operations: Loss from operations for the three months ended December 31, 2023 was $6.4 million, a decrease of $0.2 million as compared to $6.6 million for the same period in 2022.

Other Income/(Expenses), Net: Other income/(expenses), net for the three months ended December 31, 2023 reflected other income of $1.6 million, compared to other income of $0.3 million for the same period in 2022. The net change was primarily driven by exchange rate fluctuations related to Lineage’s international subsidiaries and fair market value changes in marketable equity securities.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended December 31, 2023 was $4.8 million, or $0.03 per share (basic and diluted), compared to a net loss of $6.4 million, or $0.03 per share (basic and diluted), for the same period in 2022.

Full Year Operating Results

Revenues: Lineage’s revenue is generated primarily from licensing fees, collaboration revenues, royalties, and research grants. Total revenues for the year ended December 31, 2023 were $8.9 million, a decrease of $5.8 million as compared to $14.7 million for the same period in 2022. The decrease was primarily driven by lower collaboration and licensing 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, 2023 were $33.0 million, a decrease of $3.5 million as compared to $36.5 million for the same period in 2022.

R&D Expenses: R&D expenses for the year ended December 31, 2023 were $15.7 million, an increase of $1.7 million as compared to $14.0 million for the same period in 2022. The increase was primarily driven by $0.4 million in OpRegen program expenses, $1.2 million in OPC1 program expenses, and $2.0 million in preclinical programs. These increases were partially offset by $1.9 million in other research and development programs, primarily related to reduced manufacturing activities.

G&A Expenses: G&A expenses for the year ended December 31, 2023 were $17.3 million, a decrease of approximately $5.2 million as compared to $22.5 million for the same period in 2022. The decrease was primarily attributable to $4.2 million in lower litigation and legal expenses, as well as an overall reduction in costs incurred for services provided by third parties, consulting costs, and rent-related expenses.

Loss from Operations: Loss from operations for the year ended December 31, 2023 was $24.7 million, an increase of $2.2 million as compared to $22.5 million for the same period in 2022.

Other Income/(Expenses), Net: Other income (expenses), net for the year ended December 31, 2023 reflected other income of $1.5 million, compared to other expense of ($3.3) million for the same period in 2022. The net change was primarily attributable to fluctuations in intercompany balances and related exchange rates applicable to Lineage’s international subsidiaries, as well as fair market value changes in marketable equity securities.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the year ended December 31, 2023 was $21.5 million, or $0.12 per share (basic and diluted), compared to a net loss of $26.3 million, or $0.15 per share (basic and diluted), for 2022.

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing novel or "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) 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 Eterna Therapeutics Inc.
