Lineage Reports Third Quarter 2021 Financial Results and Highlights Progress From Clinical Cell Therapy Programs

• OpRegen^® Continues to Demonstrate Functional and Anatomical Improvements in Patients with Dry AMD
• Performance Testing Underway to Support New Delivery Device for OPC1 Clinical Trials
• Cash, Cash Equivalents, and Marketable Securities of $65.1 Million

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing allogeneic cell therapies for unmet medical needs, today reported financial and operating results for the third quarter 2021. Lineage will host a conference call today at 4:30 p.m. Eastern Time to discuss its third quarter 2021 financial results and to provide a business update.

“Lineage’s approach is to produce specific types of human cells and stably transplant those cells as a treatment for serious medical conditions. We believe our approach, in certain settings, can generate clinical outcomes beyond the reach of traditional methods, as evidenced by the restoration of retinal tissue in patients in our dry AMD trial and the restoration of a tissue matrix in patients in our spinal cord injury trial,” stated Brian M. Culley, Lineage CEO. “During the third quarter, we reported positive interim outcomes in patients with dry AMD with geographic atrophy, initiated performance testing of our OPC1 delivery device for spinal cord injury, and we expanded our executive team with the appointment of a new General Counsel. Looking ahead, we are preparing for engagement with FDA for our OpRegen program to discuss aspects of product designation, manufacturing plans, and later-stage clinical development. In parallel, we look forward to the initiation of our OPC1 and novel delivery device clinical safety study early next year. We believe our technology platform has broad potential beyond even the indications we currently are pursuing and while we continue to advance our three clinical-stage programs, we also are evaluating new applications of our technology, either on our own or through strategic alliances.”

Some of the milestones achieved in the third quarter include:

- Presented OpRegen clinical data at the 54^th Annual Scientific Meeting of the American Retina Society from the ongoing Phase 1/2a study of OpRegen for the treatment of dry-AMD with GA; statistically significant evidence of a treatment effect with OpRegen was observed in Cohort 4 better vision patients.

- Reported continued positive interim clinical data with OpRegen: 8/12 (67%) of the Cohort 4 patients’ treated eyes were at or above baseline visual acuity at their last assessment, based on per protocol scheduled visits ranging from 9 months to over 3 years post-transplant, while visual acuity predictably declined in the majority of untreated eyes; notably, three patients with evidence of retinal restoration and confirmed history of GA growth continued to demonstrate areas of retinal restoration as of their last per protocol assessments, ranging from 9 months to 33 months following treatment.

- Announced the appointment of George A. Samuel III as General Counsel and Corporate Secretary. Mr. Samuel brings extensive corporate, transactional, intellectual property and commercial expertise which spans nearly 15 years across the life sciences and technology sectors as well as in private practice.

- Featured in the B. Riley Securities Fall 2021 “Growth Biotech Best Idea” Virtual Series as well as the 2021 Cantor Fitzgerald Virtual Global Healthcare Conference.

Some of the events and milestones anticipated by Lineage include:

- OpRegen Program

• Additional interim data from the Phase 1/2a clinical study to be featured at the 2021 American Academy of Ophthalmology Annual Meeting in a presentation on November 13, 2021, as part of the Gene and Cell-Based Therapies Session, by Michael S. Ip, M.D., Professor, Department of Ophthalmology at the David Geffen School of Medicine at the University of California, Los Angeles.
• Multiple interactions with the U.S. Food and Drug Administration (FDA) planned to discuss product designation, manufacturing plans, and later-stage clinical development, anticipated to begin in Q4 2021 and continue in Q1 2022.

- OPC1 Program

• Complete evaluation of a novel Parenchymal Spinal Delivery (PSD) system in non-clinical testing; anticipated in Q4 2021.

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities totaled $65.1 million as of September 30, 2021. Marketable securities of $4.3 million as of September 30, 2021 include the Company’s remaining ownership in OncoCyte Corporation (“OncoCyte”) and Hadasit Bio-Holdings Ltd.

Third Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from research grants, royalties, and licensing fees. Total revenues for the three months ended September 30, 2021 were approximately $2.3 million, an increase of $1.7 million as compared to $0.6 million for the same period in 2020. The increase was primarily related to a $1.6 million increase in royalty revenues, and a $0.3 million increase in licensing revenues in connection with a collaboration agreement, partially offset by a $0.2 million decrease in grant revenues.

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, 2021 were $8.1 million, an increase of $0.9 million as compared to $7.2 million for the same period in 2020.

R&D Expenses: R&D expenses for the three months ended September 30, 2021 were $2.8 million, a decrease of approximately $0.8 million as compared to $3.6 million for the same period in 2020. The decrease was primarily driven by lower VAC program expenses, related to a non-recurring prior year accrual of a $1.6 million signature fee to Cancer Research UK, partially offset by an increase in OPC1 expenses resulting from a return of unspent project funds of approximately $0.8 million in the prior year period from a former Asterias BioTherapeutics, Inc. (“Asterias”) service provider.

G&A Expenses: G&A expenses for the three months ended September 30, 2021 were $5.3 million, an increase of approximately $1.7 million as compared to $3.6 million for the same period in 2020. The increase was primarily attributable to increases of $0.8 million in litigation and other expenses related to Lineage’s merger with Asterias, and $0.5 million in share-based compensation.

Loss from Operations: Loss from operations for the three months ended September 30, 2021 was approximately $6.8 million, an increase of $0.1 million as compared to $6.7 million for the same period in 2020.

Other Income/(Expenses), Net: Other income/(expenses), net for the three months ended September 30, 2021 reflected other expense, net of ($2.0) million, compared to other expense, net of ($1.2) million for the same period in 2020. The variance was primarily related to a decrease in the value of Lineage’s OncoCyte shares, a decrease in interest income following settlement of the Juvenescence Limited note receivable in the prior year, and no sales of marketable equity securities as compared to the prior year’s quarter.

Net loss attributable to Lineage: The net loss attributable to Lineage for the three months ended September 30, 2021 was $7.8 million, or $0.05 per share (basic and diluted), compared to a net loss attributable to Lineage of $7.8 million, or $0.05 per share (basic and diluted), for the same period in 2020.
