Alzheimer’s disease

• Announced topline results from the Phase 2a CLEAR MIND trial of Lomecel-B™ for the treatment of mild Alzheimer’s disease:

  • The study met the primary safety endpoint, and no patient experienced Alzheimer’s Related Imaging Abnormality (ARIA);

  • The study also met its secondary endpoint, a prespecified composite Alzheimer’s Disease (CADS) endpoint with a prespecified p-value of p<0.1.

• Additional clinical data and biomarker data announced in December, 2023 showed statistically significant improvements in the following clinical and biomarker endpoints in specific Lomecel-B™ groups compared to placebo, as follow:

  • Cognitive function improved as measured by Montreal Cognitive Assessment (MoCA) (p<0.05);

  • Daily life activity increased as assessed by the caregiver and measures by Alzheimer’s Disease Cooperative Study Activities of Daily Living (ADCS-ADL) (p<0.05);

  • Brain MR imaging demonstrated whole brain volume loss slowed accompanied by significant preservation of left hippocampal volume (both p<0.05);

  • Brain neuroinflammation as measured by diffuse tensor imaging (DTI) also diminished (p<0.01).

• These results support the therapeutic potential of Lomecel-B™ in the treatment of mild Alzheimer’s disease and provided evidence-based support for further clinical development;

• Company anticipates presenting CLEAR MIND results at major medical meetings in 2024.

Aging-related Frailty

• Company has discontinued its clinical trial in Japan to evaluate Lomecel-B™ for Aging-related Frailty in order to focus on its strategic priority in HLHS;

• Longeveron management continues to believe in the potential of Lomecel-B™ in this disease state and will evaluate options for continued development at a future date.

Financial Results for Year Ended December 31, 2023

• Revenues, Cost of Revenues and Gross Profit: Revenues for the years ended December 31, 2023 and 2022 were $0.7 million and $1.2 million, respectively. 2023 revenues decreased $0.5 million, or 42%, when compared to 2022 as a result of decreased grant and lower participant demand for our Bahamas Registry Trial. Grant revenue for the years ended December 31, 2023 and 2022 was less than $0.1 million and $0.3 million, respectively. The decrease of $0.2 million, or 85%, when compared to 2022, was primarily due to a reduction in grant funds available due in part to the completion of the grant-funded clinical trials. Clinical trial revenue, which is derived from the Bahamas Registry Trial, for the years ended December 31, 2023 and 2022 was $0.7 million and $0.9 million, respectively. Clinical trial revenue for the year ended December 31, 2023 decreased by $0.2 million, or 29%, when compared to 2022 as a result of decreased participant demand.

• Related cost of revenues: Cost of revenues was $0.5 million and $0.7 million for the years ended December 31, 2023 and 2022, respectively. The decrease of $0.2 million, or 33%, was primarily due to the decrease in the revenues earned from the Bahamas Registry Trials and reduced direct costs associated with our grants program. This resulted in a gross profit of approximately $0.2 million for the year ended December 31, 2023, a decrease of $0.3 million, or 56%, when compared with a gross profit of $0.5 million for 2022.

• General and Administrative Expense: General and administrative expenses for the year ended December 31, 2023 increased to approximately $11.4 million, compared to $8.1 million for the same period in 2022. The increase of approximately $3.3 million, or 40%, was primarily related to an increase of $1.6 million for compensation and benefit expenses (including $0.4 million of separation costs), $1.0 million in legal, professional and consulting fees, $0.4 million of public company expenses, $0.2 million in equity-based compensation costs allocated to general and administrative expenses, and $0.1 million for higher board fees.

• Research and Development Expenses: Research and development expenses for the year ended December 31, 2023 decreased to approximately $9.1 million, from approximately $9.4 million for the same period in 2022. The decrease of $0.3 million, or 3%, was primarily due to decreases of $0.5 million in equity-based compensation allocated to research and development expenses and $0.3 million in compensation and benefits, offset by increases of $0.4 million in supplies and costs to manufacture Lomecel-B™ and $0.2 million in research and development expenses that were not reimbursable by grants.

• Selling and Marketing Expenses: Selling and marketing expenses for the years ended December 31, 2023 and 2022 were $0.8 million and $1.0 million, respectively. The decrease of $0.2 million, or 24%, was primarily due to decreases in investor relations and international development expenses.

• Non-operating Lawsuit expense: Non-operating Lawsuit expense for the years ended December 31, 2023 and 2022 was less than $0.1 million and approximately $1.4 million, respectively. Additional detail can be found in Part I, Item 3 “Legal Proceedings” of this Form 10-K. Legal expenses incurred in ordinary business activities are reported within general and administrative expenses.

• Other tax credits: Other tax credits for each of the years ended December 31, 2023 and 2022 was less than $0.1 million and $0.3 million, respectively. Other tax credit was greater in 2022 due to receiving the Employee Retention Credit under the CARES Act which encourages businesses to keep employees on their payroll. Eligible businesses receive a refundable tax credit of up to 50% of up to $10,000 in wages paid.

• Other Expense (Income), net: Other expense for the years ended December 31, 2023 and 2023 was $0.4 million and $0.8 million, respectively. Other expense for 2023 decreased mainly as a result of non-operating lawsuit expenses of $1.4 million in 2022, compared to less than $0.1 million in 2023. This decrease was partially offset by realized losses on sales of marketable securities of $0.3 million, write-offs of intangible assets of $0.3 million and reduced benefit of tax credits of $0.3 million. Also recorded in other (expense) income in 2022 was approximately $27,000 for a gain resulting from foreign currency changes and $27,000 of sublease rental income.

• Net Loss: Net loss increased to approximately $21.4 million for the year ended December 31, 2023, from a net loss of $18.8 million for the same period in 2022. The increase in the net loss of $2.6 million, or 14%, was for reasons outlined above.

• Subsequent events:

  • In line with the Company’s 2024 strategic direction to focus its resources on HLHS and AD and to manage its cash spend, the Company decided to discontinue its previously disclosed clinical trial in Japan to evaluate Lomecel-B™ for Aging-related Frailty.

  • On February 21, 2024, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to effect a reverse stock split of its outstanding shares of Class A common stock and Class B common stock at a ratio ranging from one-for-five (1:5) to one-for-fifteen (1:15), with the exact ratio to be set within that range at the discretion of its Board of Directors without further approval or authorization of its stockholders. The date of the reverse stock split and the ratio has not yet been determined.

As of December 31, 2023, the Company had $5.4 million in cash and cash equivalents and marketable securities. We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2024. We are actively seeking financing opportunities to extend our cash runway while taking measures to reduce our cash expenditures as we focus our resources on our primary strategic program in HLHS. These cost saving measures include the discontinuation of our Aging-related Frailty clinical trial in Japan, related staff reductions and continued prudent management of discretionary spend.

Conference Call and Webcast

Management will host a conference call today at 5:00 p.m. ET to discuss the Company’s third quarter 2023 financial results and provide a business update.
