Key Financial Metrics

Note: The company has no revenue and operates at a loss. Margins are not applicable.

Material Changes vs. Prior Period

• Net Loss Increase: Net loss increased by $10.97 million (51%) compared to Q1 2024, driven primarily by higher operating expenses.
• G&A Expense Surge: General and administrative expenses increased by $9.09 million (120%). This was primarily due to a $7.5 million increase in third-party legal fees and associated costs, alongside a $1.4 million increase in employee compensation and stock-based compensation.
• R&D Expense Growth: R&D expenses increased by $1.43 million (9%), attributed to increased headcount, equity awards, and clinical trial costs for cardiovascular programs (LX2006 and LX2020).
• Liquidity Position: Total cash, cash equivalents, and investments decreased by approximately $21.6 million from the beginning of the period to $106.9 million as of March 31, 2025.

Guidance, Outlook, and Risks

Capital Reallocation and Runway: In April 2025, management identified approximately $20 million in capital to redeploy from preclinical and non-cardiac pipeline activities toward the lead programs LX2006 and LX2020. This included a limited reduction in force impacting approximately 15% of employees. Management estimates current resources are sufficient to fund operations into 2027.

Clinical Progress:

• LX2006 (FA Cardiomyopathy): Interim data showed dose-responsive increases in frataxin expression and improvements in cardiac biomarkers. The company has aligned with the FDA on a registrational development plan with an accelerated approval pathway.
• LX2020 (PKP2-ACM): Early data showed increased PKP2 protein expression and reduction in PVCs. An interim data readout is expected in the second half of 2025.

Financing: On March 24, 2025, the company entered into a Sales Agreement for an At-The-Market (ATM) program to sell up to $75.0 million of common stock. No shares had been sold under this program as of March 31, 2025.

Risks and Contingencies:

• Litigation: The company is involved in ongoing litigation with Rocket Pharmaceuticals, Inc., alleging misappropriation of trade secrets. Lexeo has filed counterclaims. Management does not currently expect a material adverse effect on timelines but notes the uncertainty.
• Regulatory & Development: Risks include the novel nature of gene therapy, potential manufacturing delays, and the unpredictability of clinical trial outcomes.
• Capital Needs: The company expects to incur significant losses for the foreseeable future and will require additional funding to achieve profitability.

Investor Verification Checklist

• Verify the status and terms of the newly established $75 million ATM program and any subsequent sales activity.
• Monitor the outcome of the ongoing litigation with Rocket Pharmaceuticals, Inc., including potential financial exposure or operational injunctions.
• Confirm the timeline for the anticipated interim data readout for LX2020 in the second half of 2025.
• Review the impact of the 15% workforce reduction on the company's ability to execute its accelerated development plan for LX2006.
• Assess the sufficiency of the $106.9 million cash balance against the projected burn rate to ensure the runway extends into 2027 as stated.
