YSJA Rabies Vaccine Phase III Clinical Trial Approval for Simplified Regimen

On October 25, 2024, the Company received approval from the National Medical Products Administration (NMPA) in China to conduct a phase III clinical trial evaluating the immunogenicity and safety of a simplified four-dose regimen for its YSJA rabies vaccine. The trial, scheduled to commence in late December 2024, will enroll 2,380 participants and compare the immunogenicity and safety of the YSJA rabies vaccine across two distinct four-dose immunization schedules against the existing Essen regimen (1-1-1-1-1). This randomized, double-blind, controlled study is expected to conclude by the third quarter of 2025.

The study aims to strengthen the competitiveness of the YSJA rabies vaccine in the rapidly growing rabies vaccine market, demonstrate its clinical superiority, and garner broader recognition and support from hospitals, academic institutions, and industry stakeholders in China and globally.

First Half of Fiscal Year 2025 Financial Results

Total Revenues

Total revenues reached RMB 371.9 million, compared to RMB 273.1 million in the same period of FY2024, representing a year-over-year growth of 36.2%. This increase was primarily driven by higher sales volume, attributable to increased batch approvals and doses available for sale, as well as the targeted and effective marketing initiatives.

Gross Profit

Gross profit was RMB 307.3 million, with a gross margin of 82.6%, compared to RMB 220.9 million and an 80.9% gross margin in the same period of FY2024. The improvement in gross margin was primarily driven by a reduction in unit production cost.

Selling and Marketing Expenses

Selling and marketing expenses totaled RMB 137.1 million, compared to RMB 157.7 million in the same period of FY2024, reflecting a 13.1% decrease. This reduction was attributed to cost reduction initiatives during the first half of FY2025.

General and Administrative Expenses

General and administrative expenses were RMB 70.8 million, up from RMB 67.6 million in the same period of FY2024. The increase was mainly driven by costs associated with workforce reduction.

Research and Development Expenses

Research and development expenses were RMB 68.5 million, compared to RMB 178.9 million in the same period of FY2024, representing a 61.7% decrease. This decline was primarily driven by reductions in testing fees, clinical trial fees, and consulting service fees following the conclusion of the Covid-19 vaccine clinical study.

EBITDA and Adjusted EBITDA

EBITDA^[2] (Non-GAAP) and Adjusted EBITDA^[3] (Non-GAAP) was RMB 53.8 million and RMB 57.9 million, compared to negative EBITDA of RMB 138.6 million and negative adjusted EBITDA of RMB 159.5 million (Non-GAAP) respectively, in the same period of FY2024.

FY2025 Guidance Update

The Company also projects Adjusted EBITDA to range between RMB 76 million and RMB 89 million. These projections reflect the Company's positive outlook for the current fiscal year, which would establish significant foundation for fiscal year 2026.

The above outlook is based on information available as of the date of this press release and reflects the Company's current and preliminary views regarding its business situation and market conditions, which are subject to change.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses certain non-GAAP measures, including Adjusted EBITDA and adjusted net income (loss), as supplemental measures to review and assess its operating performance. The presentation of the non-GAAP financial measure is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP. The Company defines EBITDA as net income (loss) before income tax expense (benefit), financial expenses - net and depreciation and amortization. The Company defines Adjusted EBITDA as net income (loss) before income tax expense (benefit), financial expenses - net, and depreciation and amortization ("EBITDA") adjusted to exclude share-based compensation expenses, late fees related to social security insurance, other income (expense) - net, fair value changes of warrant liability, and government grants. The Company defines adjusted net income (loss) as net income (loss) excluding share-based compensation expenses and loss on disposal of property, plant and equipment. The Company presents the non-GAAP financial measures because they are used by the management to evaluate the operating performance and formulate business plans. The Company also believes that the use of the non-GAAP measures facilitates investors' assessment of its operating performance as this measure excludes certain finance or non-cash items that the Company does not believe directly reflect its core operations. The Company believes that excluding these items enables us to evaluate our performance period-over-period more effectively and relative to our competitors.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using Adjusted EBITDA is that it does not reflect all items of income and expenses that affect the Company's operations. Share-based compensation and loss on disposal of property, plant and equipment have been and may continue to be incurred in the business. Further, the non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

The Company compensates for these limitations by reconciling the non-GAAP financial measure to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating the Company's performance. The Company encourages you to review its financial information in its entirety and not rely on a single financial measure.

Reconciliations of LakeShore Biopharma's non-GAAP financial measures to the most comparable U.S. GAAP measure are included at the end of this press release.
