CARLSBAD, Calif. / May 22, 2023 / Business Wire / Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing allogeneic cell therapies for unmet medical needs, today reported that the Company is expected to be added to the broad-market Russell 3000^® Index at the conclusion of the 2023 Russell indexes annual reconstitution, effective as of the U.S. market open on June 26, 2023, according to a preliminary list of additions posted to the FTSE Russell website, following the close of the U.S. markets on May 19, 2023.

Annual Russell indexes reconstitution captures the 4,000 largest U.S. stocks as of April 28, 2023, ranking them by total market capitalization. Membership in the U.S. all-cap Russell 3000^® Index, which remains in place for one year following reconstitution, means automatic inclusion in the large-cap Russell 1000^® Index or small-cap Russell 2000^® Index as well as the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.

“We are pleased that Lineage is expected to be added into the Russell 3000 Index next month. Our inclusion among larger market cap companies should help to expand investor awareness, increase institutional ownership, and provide additional liquidity in our stock,” stated Brian M. Culley, Lineage CEO, “This recognition of our progress comes during an exciting time, as our partners Roche and Genentech enroll patients in a Phase 2a clinical trial of OpRegen^® for the treatment of dry age-related macular degeneration, as we prepare for further clinical testing of our OPC1 treatment for spinal cord injury, and as we advance our other treatments for cancer, hearing loss, and vision loss. Overall, we believe a deeper understanding of Lineage’s strategic objectives can help increase support for our novel and exciting approach to cell transplant medicine.”

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Lineage’s programs are based on its robust proprietary cell-based therapy platform and associated in-house development and manufacturing capabilities. With this platform Lineage develops and manufactures specialized, terminally differentiated human cells from its pluripotent and progenitor cell starting materials.

Lineage’s clinical and preclinical programs are in markets with billion dollar opportunities and include five allogeneic (“off-the-shelf”) product candidates: (i) OpRegen, a retinal pigment epithelial cell therapy in Phase 2a development for the treatment of geographic atrophy secondary to age-related macular degeneration, is being developed under a worldwide collaboration with Roche and Genentech, a member of the Roche Group; (ii) OPC1, an oligodendrocyte progenitor cell therapy in Phase 1/2a development for the treatment of acute spinal cord injuries; (iii) VAC2, a dendritic cell therapy produced from Lineage’s VAC technology platform for immuno-oncology and infectious disease, currently in Phase 1 clinical development for the treatment of non-small cell lung cancer; (iv) ANP1, an auditory neuronal progenitor cell therapy for the potential treatment of auditory neuropathy; and (v) PNC1, a photoreceptor neural cell therapy for the potential treatment of vision loss due to photoreceptor dysfunction or damage.
