Balance Sheet Highlights

Cash, cash equivalents, and marketable securities totaled $72 million as of June 30, 2022, which is expected to support operations through Q2 2024.

Second Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from licensing fees, royalties, collaboration revenues, and research grants. Total revenues for the three months ended June 30, 2022 were approximately $4.6 million, a net increase of $4.0 million as compared to $0.5 million for the same period in 2021. The increase was primarily related to licensing fees recognized from deferred revenues in connection with the $50.0 million upfront licensing payment received in the first quarter of 2022 from 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 June 30, 2022 were $8.6 million, an increase of $1.1 million as compared to $7.5 million for the same period in 2021.

R&D Expenses: R&D expenses for the three months ended June 30, 2022 were $3.3 million, a net increase of $0.4 million as compared to $2.9 million for the same period in 2021. The net increase was driven by $0.1 million in higher OpRegen related expenses to support the Roche Collaboration. Another $0.2 million and $0.1 million of the increase was related to R&D spending on the new auditory neuron and photoreceptor cell therapy programs, respectively.

G&A Expenses: G&A expenses for the three months ended June 30, 2022 were $5.3 million, a net increase of approximately $0.7 million as compared to $4.5 million for the same period in 2021. The increase was primarily attributable to $0.4 million in payroll and related benefits expense, and $0.5 million in share-based compensation, partially offset by $0.2 million in lower investor relations expense.

Loss from Operations: Loss from operations for the three months ended June 30, 2022 was $4.2 million, a decrease of $2.9 million as compared to $7.1 million for the same period in 2021.

Other Income/(Expenses), Net: Other income (expenses), net for the three months ended June 30, 2022 reflected other expense, net of ($2.5) million, compared to other income, net of $2.1 million for the same period in 2021. The net change was primarily driven by exchange rate fluctuations related to Lineage’s international subsidiaries, as well as a decrease in the value of marketable equity securities, and partially offset by the gain on extinguishment of debt from Lineage’s Paycheck Protection Program loan forgiveness recognized in the prior year’s quarter.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended June 30, 2022 was $6.8 million, or $0.04 per share (basic and diluted), compared to a net loss attributable to Lineage of $4.8 million, or $0.03 per share (basic and diluted), for the same period in 2021.
