Lineage Cell Therapeutics Reports Third Quarter 2019 Financial Results and Provides Business Update

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel cellular therapies for unmet medical needs, reported financial and operating results for the third quarter ended September 30, 2019. Lineage management will host a conference call and webcast today at 4:30 p.m. Eastern Time/1:30 p.m. Pacific Time to discuss its third quarter 2019 financial results and to provide a business update.

"We are excited about our cell therapy programs and how they may benefit patients with serious medical conditions such as dry AMD, spinal cord injury, and cancer," stated Brian M. Culley, CEO of Lineage. "We believe that Lineage has one of the largest and most comprehensive patent estates in cell therapy and that our clinical-stage programs are making important advances. We also recently implemented additional cost-cutting measures that will reduce our planned 2020 net operational spend to $16 million, $8 million to $12 million less than our previous estimate of $24 million to $28 million. Under this plan, our primary goal will be to complete enrollment in our Phase I/IIa clinical study of OpRegen early next year and collect the follow-up data to guide our late-stage study design and partnership discussions. We also have completed the transfer of OPC1 to our manufacturing facility and will continue our efforts to introduce manufacturing enhancements to OPC1 in preparation for the initiation of a randomized clinical study in 2021. We believe reducing our cash burn and focusing on OpRegen, our nearest-term high value asset, as well as on finding a strong marketing partner for Renevia, is the best way to create near-term shareholder value. In August 2020, we also are entitled to receive our final payment of $24.6 million in principal and interest for the 2018 sale of AgeX Therapeutics shares to Juvenescence, an amount which exceeds our anticipated cash needs from now through the end of next year."

"Additionally, we are looking forward to hosting two therapeutic area experts in ophthalmology and spinal cord injury at Solebury Trout's KOL Event for analysts and investors in New York City on November 15, 2019," added Mr. Culley. "Our executive team will be joined by renowned experts Allen C. Ho, M.D. FACS, Wills Eye Hospital Attending Surgeon and Director of Retina Research, and John Steeves, B.Sc., Ph.D., Emeritus Principal Investigator at ICORD and Professor in the Department of Neuroscience at the University of British Columbia. We will be providing an update on our OpRegen and OPC1 clinical programs, as well as an update on the SCiStar Clinical Study for the treatment of spinal cord injury."

Recent Significant Highlights

• Provided an update of our Phase I/IIa clinical study of OpRegen in patients with dry age-related macular degeneration (dry AMD) with geographic atrophy at the 2019 American Academy of Ophthalmology Annual Meeting (AAO 2019) in San Francisco, CA on October 14, 2019. Data from the study demonstrated that treatment with OpRegen continued to be well tolerated and, at the furthest time point collected, all four Cohort 4 patients treated to date had better visual acuity on an Early Treatment Diabetic Retinopathy Scale (ETDRS) in the treated eye (range +8 to +19 letters) than in the untreated eye (range -2 to +7 letters). The largest increase recorded at any single timepoint in a Cohort 4 patient was +22 letters. Cohort 4 patients have better baseline vision and less advanced disease than Cohorts 1-3 patients, who were legally blind at baseline. Previously reported structural improvements in the retina and decreases in drusen density observed in some patients were maintained and there was evidence of the continued presence of transplanted OpRegen cells in patients treated in the first 3 cohorts, some over 3 years following administration. Of note, the first patient successfully dosed using the Orbit Subretinal Delivery System (Orbit SDS) as well as a new Thaw-and-Inject (TAI) formulation of OpRegen was also demonstrating signs of improved visual acuity, having gained 13 letters in the 3 months following administration as assessed by ETDRS. Overall, OpRegen appeared well tolerated with preliminary evidence of improved structural changes and potential improvement in visual acuity following treatment in some patients.

• Announced that Renevia, the Company's facial aesthetics product, has been granted a Conformité Européenne (CE) Mark. Renevia received a Class III classification with an intended use in adults as a resorbable matrix for the delivery of autologous adipose tissue preparations to restore and/or augment facial volume after subcutaneous fat volume loss for the treatment of facial lipoatrophy. The CE Mark provides Lineage, or its authorized agent, the authority to market and distribute Renevia throughout the European Union (EU) and in other countries that recognize the CE Mark. The Company has engaged an EU-based business development agent to identify opportunities to partner this asset and has begun the process of engaging with commercially capable partners for Renevia.

• Completed the launch of our new corporate brand and identity as well as a change in corporate name to Lineage Cell Therapeutics, Inc., reflecting our commitment to becoming an innovative, leading cell therapy company and highlighting our extensive cell therapy platform. In conjunction with the name change, the Company's ticker symbol was changed to "LCTX" on August 12, 2019. The Company also relocated its corporate headquarters to Carlsbad, California, effective August 12, 2019, a move which provides proximity to world-leading academic centers, public and private cell therapy peers, and offers more centralized decision-making, cost-savings, and access to an extensive network of experienced staff. The Company also terminated shared services with OncoCyte Corporation (OncoCyte, NYSE American: OCX) and AgeX Therapeutics, Inc. (AgeX, NYSE American: AGE) on September 30, 2019, an important step in our plan to simplify our business structure.

• Converted approximately 43% of our investment in OncoCyte into cash to support our operations with the sale of 6,250,000 shares of OncoCyte common stock for net proceeds totaling $10.7 million. Lineage continues to own approximately 16% or 8.4 million shares of OncoCyte's outstanding common stock. Based on the closing price of OncoCyte's common stock on November 8, 2019, the value of our remaining OncoCyte shares is approximately $14.1 million.

Near Term Milestones for 2019 and 2020

• Complete patient enrollment in the United States with the Orbit SDS in the ongoing Phase I/IIa clinical study of OpRegen for the treatment of dry AMD, expected in Q1 2020.
• Obtain VAC2 immunogenicity data from the initial patients in the ongoing Phase I study in NSCLC (non-small cell lung cancer) run by Cancer Research UK, expected around year end.
• Present new OpRegen data from the ongoing Phase I/IIa clinical study at the Association for Research in Vision and Ophthalmology Meeting (ARVO) in May 2020.
• Advance the OPC1 manufacturing program by introducing enhancements to the manufacturing process in our GMP manufacturing facility, ongoing throughout 2020.
• Meet with the FDA to discuss the manufacturing and clinical development of OPC1, around the middle of 2020.
• Identify an external partner for commercialization of Renevia in Europe, targeted for the first half of 2020.
• Continue engagement with the investment and medical communities with participation at medical and healthcare industry conferences, ongoing throughout 2020.
• Strengthen existing partnerships with the National Institutes of Health, the Israel Innovation Authority, the California Institute for Regenerative Medicine and Cancer Research UK.

Balance Sheet Highlights

Cash, cash equivalents and marketable securities totaled $35.7 million as of September 30, 2019. Marketable securities include our remaining ownership stakes in OncoCyte, AgeX and Hadasit Bio-Holdings Ltd (Hadasit), which are now all under 20% of their respective total outstanding shares. Lineage sold 6,250,000 shares of OncoCyte's common stock in the third quarter of 2019 for net proceeds of $10.7 million. Lineage also sold 651,839 shares of AgeX common stock in the third quarter of 2019 for net proceeds of $1.6 million and 647,397 shares of Hadasit common stock in July 2019 for net proceeds of $1.2 million.

Lineage's promissory note due from Juvenescence Limited had an outstanding balance (principal plus accrued interest) of $23.2 million as of September 30, 2019. Unless earlier converted into Juvenescence ordinary shares, the promissory note is payable in cash, plus accrued interest at 7% per year, at maturity in August 2020. If Juvenescence completes an initial public offering (IPO) resulting in gross proceeds of not less than $50.0 million, the promissory note automatically converts into the Juvenescence securities issued in the IPO based on the per-share price to the public in the IPO, subject to an upward adjustment in the number of shares that would be issued to Lineage upon such conversion if the 20-day volume-weighted average trading price of one share of common stock of AgeX before the IPO is priced above $3.00. If the promissory note is converted, the Juvenescence ordinary shares will be a marketable security that Lineage may use to supplement its liquidity, as needed and as market conditions allow.

In summary, as of September 30, 2019, the value of the Company's cash, marketable securities, and the balance of a promissory note due to it in August 2020 were in excess of $58.9 million.

Lineage expects to spend approximately $6 million in the fourth quarter of 2019. The Company has implemented significant cost savings initiatives and now anticipates that net operational spend for 2020 will be $16 million. This planned spending level represents a significant reduction from 2019 forecasted spending levels of $34 million and 2018 spending levels of $43 million for Lineage and Asterias Biotherapeutics, Inc. (Asterias) combined. Lineage acquired Asterias on March 8, 2019.

Third Quarter Operating Results

Note regarding AgeX: On August 30, 2018, Lineage deconsolidated AgeX from its consolidated financial statements due to the sale by Lineage of 14,400,000 shares of AgeX common stock to Juvenescence and the related decrease of Lineage's ownership position in AgeX from 80.4% to 40.2%. Accordingly, Lineage ceased recognizing revenue and expenses related to AgeX and its programs on such date.

Revenues: Lineage's revenue is generated primarily from research grants, licensing fees and royalties. Total revenues for the three months ended September 30, 2019 were $0.6 million, a decrease of $0.4 million as compared to the same period in 2018. The decrease was primarily related to a $0.4 million decrease in grant revenues, which is primarily based on the timing of grant-related activities.

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, 2019 were $8.9 million, a decrease of $2.4 million as compared to the same period in 2018.

R&D Expenses: R&D expenses for the three months ended September 30, 2019 were $4.3 million, a decrease of $0.6 million as compared to the same period in 2018. The decrease was primarily related to a $0.8 million decrease from the AgeX deconsolidation and the absence of AgeX R&D expenses incurred after August 30, 2018, offset by a net increase of $0.2 million in Lineage programs primarily related to: (1) an increase of $1.4 million in OPC1 and VAC2 expenses (these programs were acquired in the Asterias merger) offset by (2) decreases of $1.2 million in Renevia, OpRegen and other research-related expenses.

G&A Expenses: G&A expenses for the three months ended September 30, 2019 were $4.6 million, a decrease of $1.8 million as compared to the same period in 2018. The decrease was primarily attributable to a $0.8 million decrease in AgeX related general and administrative expenses, a $0.5 million reduction in legal and patent expenses, a $0.4 million decrease in salaries, benefits and severance costs primarily related to terminated personnel and a $0.3 million reduction in consulting expenses, offset by a $0.2 million increase in rent expense, which is primarily related to the implementation of ASC 842 Leases in 2019.

Loss from Operations: Loss from operations for the three months ended September 30, 2019 was $8.4 million, a decrease of $2.0 million as compared to the same period in 2018.

Other Income/(Expenses), Net: Other income/(expenses), net for the three months ended September 30, 2019 reflected other expense, net of ($9.1) million, compared to other income, net of $76.9 million for the same period in 2018. The variance was primarily related to the gain on the deconsolidation of AgeX in 2018 and the changes in the value of investments in marketable equity securities for the applicable periods.
