2025 Financial Performance

Total revenues of €174.7 million, up from €169.6 million in 2024, including the recognition of variable consideration relating to the Company's research collaboration and licensing agreement for the Lyme disease program
Product sales of €157.9 million, compared to €163.3 million in 2024, reflecting the planned wind-down of third-party sales (-42.3% versus 2024). Proprietary product sales increased by 9% at constant exchange rate (CER)³
Net loss amounted to €115.2 million compared to a net loss of €12.2 million in 2024, while the prior year amount benefited from a €90.8 million net gain related to the sale of the Priority Review Voucher (PRV) received for IXCHIQ^®
Operating cash burn continued to decline, improving to €52.9 million in 2025 compared to €67.2 million in 2024 and €202.7 million in 2023

Reiterated 2026 Outlook and Financial Guidance

First Phase 3 data readout for Lyme disease vaccine candidate (VLA15) anticipated in the first half of 2026, with regulatory submissions expected to follow as planned by Pfizer, subject to positive results
- If approved, VLA15 will be the fourth vaccine successfully developed by Valneva and subsequent commercialization by Pfizer would enable Valneva to further expand and accelerate its pipeline of innovative vaccines in line with the Company's strategic vision
First Phase 2 data for tetravalent Shigella vaccine candidate S4V2 are expected mid-2026, with a decision on subsequent development steps in the second half of 2026
Further enhancement of the Company's R&D pipeline with differentiated vaccine candidates addressing areas of high unmet medical need
Total revenues for full-year 2026 are expected to range between €155 million and 170 million, including product sales between €145-160 million
- The lower product sales guidance in 2026 versus the prior year reflects continued growth of established commercial brands, offset by the planned wind-down of third-party sales, as previously guided.
Disciplined cash management will remain a priority, with operating cash burn expected to decline further in 2026, while continuing to support strategic R&D investments

Peter Bühler, Valneva's Chief Financial Officer, commented, "We are approaching the potentially transformative Phase 3 data readout for our Lyme disease vaccine candidate, an inflection point that could significantly shape our Company's future and strengthen our long‑term strategy. While 2025 tested our resilience, it also underscored the strength of our team's disciplined execution. In 2026, we remain firmly committed to prudent capital allocation to support sustainable growth and advance our strategic vision."

Commercial Portfolio

Valneva's commercial portfolio comprises three vaccines, IXIARO^®/JESPECT^®, DUKORAL^® and IXCHIQ^®. The Company's main third‑party product distribution contract concluded in 2025 and this activity is now expected to naturally wind down, as previously communicated.

Valneva's total product sales in 2025 were €157.9 million compared to €163.3 million in 2024, reflecting a 42.3% planned reduction in third party product sales (€19.2 million in 2025 versus €33.2 million in 2024). Excluding third-party sales, total product sales increased by 9% at CER.

JAPANESE ENCEPHALITIS VACCINE IXIARO^®/JESPECT^®

In 2025, IXIARO^®/JESPECT^® sales increased by 4.6% to €98.4 million, resulting from growth in the traveler's market. This compares with 2024, when IXIARO^®sales were impacted by supply constraints. Sales at CER grew by 7.2% compared to 2025.

In January 2025, Valneva secured a new $32.8 million contract with the United States Department of Defense (DoD)⁵.

CHOLERA / ETEC⁶-DIARRHEA VACCINE DUKORAL^®

In 2025, DUKORAL^® sales were €31.9 million as compared to €32.3 million in 2024. Sales in 2025 were notably affected by €1.0 million of adverse currency effects, as well as lower sales in Germany due to the gradual transition of distribution to CSL Seqirus. Sales at CER grew by 1.8%.

CHIKUNGUNYA VACCINE IXCHIQ^®

In 2025, Valneva reported IXCHIQ^® sales of €8.4 million, compared to €3.7 million in 2024. Sales in 2025 benefited from the vaccine's launch in several European countries, including the supply of doses to help contain a major chikungunya outbreak on the French island of La Réunion. This growth was partly offset by the previously communicated label and user‑restriction constraints⁷.

In January 2026, Valneva voluntarily withdrew the Biologics License Application (BLA) and Investigational New Drug (IND) application for IXCHIQ^® in the United States. The Company remains focused on expanding IXCHIQ^® access and sales in other territories, including Low- and Middle-Income Countries (LMICs), where medical need remains high.

Clinical Vaccine Programs

LYME DISEASE VACCINE CANDIDATE – VLA15

VALOR Phase 3 Results expected in the first half of 2026

Valneva and Pfizer are developing VLA15, a vaccine candidate targeting Borrelia, the bacterium that causes Lyme disease. VLA15 is the most advanced Lyme disease vaccine candidate currently in clinical development, with two Phase 3 trials underway. It leverages an established mechanism of action, inducing antibodies to Borrelia outer surface protein A (OspA) to prevent the transmission of Lyme borreliosis from infected ticks. The vaccine antigens are designed to target the six most prevalent Borrelia serotypes.

Pfizer is conducting a randomized, placebo-controlled Phase 3 field efficacy trial, VALOR (Vaccine Against Lyme for Outdoor Recreationists). Phase 3 vaccinations were completed in 2025 and VALOR trial results are expected to be reported in the first half of 2026.

Subject to positive Phase 3 results, Pfizer intends to submit a Biologics License Application (BLA) to the U.S. FDA and Marketing Authorization Application (MAA) to the European Medicines Agency in 2026. Upon approval and successful commercialization of VLA15, Valneva would be eligible to receive $143 million in initial milestone payments from Pfizer, plus sales royalties ranging from 14% to 22% and up to $100 million in cumulative sales milestones.

CHIKUNGUNYA VACCINE - IXCHIQ^®/ VLA1553

Pilot vaccination campaign ongoing in Brazil

In February 2026, Valneva and Instituto Butantan announced the initiation of a Pilot Vaccination Strategy (PVS) in Brazil using Valneva's single-shot chikungunya vaccine, IXCHIQ^®. The vaccination campaign will serve as the basis for post-marketing commitment studies evaluating the effectiveness and safety of IXCHIQ^® in a real-world setting and generating real-world evidence in a large population.

The PVS, agreed to between the Brazilian Ministry of Health (MoH) and Instituto Butantan, will be implemented in ten Brazilian municipalities strategically selected based on epidemiological and operational criteria in support of the PVS. In line with the current IXCHIQ^® label in Brazil, adults aged 18 to 59 years will be invited to participate, with the objective of achieving 20% to 40% vaccine coverage within the target population. Additionally, Valneva, through its partner Instituto Butantan, will donate up to 500,000 doses of IXCHIQ^® to the Brazilian MoH, for use in the program.

SHIGELLA VACCINE CANDIDATE – S4V2

First Phase 2 results expected mid-2026

S4V2 is the world's most clinically advanced tetravalent vaccine candidate against shigellosis, the second leading cause of fatal diarrhea worldwide. Two clinical trials of S4V2, a Phase 2 infant safety and immunogenicity trial⁸, and a Phase 2b Human Challenge trial (CHIM)⁹, sponsored by LimmaTech Biologics AG, are ongoing. First Phase 2 results are expected mid-2026. Subject to positive results for both trials, Valneva will assume responsibility for all further development¹⁰.

No approved multivalent Shigella vaccine is currently available outside of Russia or China, and the development of Shigella vaccines has been identified as a priority by the World Health Organization (WHO)¹¹. In October 2024, the U.S. FDA granted Fast Track designation to S4V2, recognizing its potential to address a serious condition and fill an unmet medical need¹². The global market opportunity for a vaccine against Shigella is estimated to exceed $500 million annually¹³.

ZIKA VACCINE CANDIDATE – VLA1601

Positive Phase 1 results announced

In 2025, Valneva announced positive safety and immunogenicity results for the Phase 1 clinical trial of VLA1601, its second-generation adjuvanted inactivated vaccine candidate against the Zika virus (ZIKV)¹⁴.

Despite the medical need, regulatory pathways and market opportunity for potential Zika vaccines remain uncertain. Valneva will therefore only consider further potential development steps for VLA1601 if private and public funding opportunities materialize.

Full Year 2025 Financial Review

(Audited¹⁵, consolidated under IFRS)

Revenues

Valneva's total revenues were €174.7 million in 2025 as compared to €169.6 million in 2024. The increase was driven by IXIARO^®/JESPECT^®and IXCHIQ^® sales.

Other revenues, including revenues from collaborations, licensing and services increased to €16.8 million in 2025 as compared to €6.3 million in 2024. The increase for 2025 was mainly attributable to the recognition of variable consideration relating to the Company's research collaboration and licensing agreement for the Lyme disease program.

Operating Result and adjusted EBITDA

Costs of goods and services sold (COGS) were €107.1 million in 2025. The gross margin on commercial product sales, excluding IXCHIQ^®, remained flat at 50.8% as compared to 50.6% in 2024. Positive effects from lower third-party product sales were offset by higher manufacturing expenditure following the completion of the manufacturing transfer to the new Almeida facility in Scotland.

Gross margin for IXIARO^®reached 59.6%, slightly lower than the 61.0% achieved in 2024. The decline for 2025 was mainly driven by higher manufacturing costs at the Almeida facility combined with lower manufacturing volumes during 2025. Gross margin for DUKORAL^® reached 33.3% for 2025 as compared to 38.7% in 2024. Batch failures during the last quarter of 2025 were the primary factor behind this margin compression. Gross margin for IXCHIQ^® was negative, impacted by €8.5 million of inventory write-offs, mostly related to the termination of the supply agreement with Serum Institute of India in December 2025. Finally, COGS of €12.5 million were attributable to the third-party distribution business, €10.8 million related to idle capacity and costs not allocated to products and €7.2 million related to services. For comparison, total COGS in 2024 were €98.5 million, including €90.0 million in cost of goods and €8.5 million in cost of services.

Research and development expenses amounted to €85.3 million in 2025, compared to €74.1 million in 2024. This increase for 2025 was mainly driven by higher costs related to the Shigella vaccine under the R&D collaboration agreement with LimmaTech Biologics AG and increased IXCHIQ^® post-marketing obligations.

Marketing and distribution totaled €37.4 million in 2025, down from €52.4 million in 2024. The decrease for 2025 primarily reflects reduced advertising and promotional spending related to IXCHIQ^®, partly offset by higher warehousing and distribution costs.

General and administrative expenses decreased to €37.3 million in 2025 from €42.8 million in 2024. The reduction for 2025 was primarily driven by lower recruiting costs, reduced insurance charges, and savings in advisory and professional services.

Other income, net of other expenses, decreased to €10.4 million in 2025 from €20.7 million in 2024. The decline for 2025 was mainly driven by lower R&D tax credits in Austria and reduced grant income from Scottish Enterprise recognized during 2025.

Valneva recorded an operating loss of €82.1 million in 2025 compared to an operating profit of €13.3 million in 2024. This change was primarily driven by the absence of the 2024 net gain of €90.8 million related to the PRV sale.

The adjusted EBITDA loss (as defined below) in 2025 was €59.4 million, compared to an adjusted EBITDA profit of €32.9 million in 2024, which in 2024 had benefited from the gain associated with the PRV sale.

Net Result

Valneva recorded a net loss of €115.2 million in 2025, compared to a net loss of €12.2 million in 2024. Net result, operating loss and adjusted EBITDA are not comparable between 2024 and 2025 because of the 2024 gain from the PRV sale.

Finance expense and currency effects resulted in a net finance expense of €32.1 million in 2025, compared to €24.8 million in 2024. This increase was mainly attributable to €17.9 million higher interest expenses, mostly related to one-time effects from the 2025 repayment of the loan with Deerfield Management Company and OrbiMed (D&O).

Cash Flow and Liquidity

Net cash used in operating activities amounted to €52.9 million in 2025, compared to €67.2 million in 2024. The reduction in 2025 was driven by efficient cost management.

Cash used in investing activities amounted to €1.7 million in 2025, compared to cash inflows of €76.9 million in 2024. The 2025 outflows were primarily related to purchases of equipment, partly offset by interest income. In 2024, investing cash inflows were driven by €90.8 million in net proceeds from the sale of the PRV.

Net cash used in financing activities amounted to €0.6 million in 2025, compared to a net cash inflow of €30.7 million in 2024. Financing cash inflows in 2025 included €27.4 million in net proceeds mainly related to transactions using the Company's at-the-market facility program, largely offset by interest payments and one-time effects related to the repayment of the D&O loan.

Cash inflows for 2024 included €57.1 million in proceeds from a private placement.

Cash and cash equivalents were €109.7 million as at December 31, 2025, compared to €168.3 million as at December 31, 2024.

Non-IFRS Financial Measures

Management uses and presents IFRS results as well as the non-IFRS measure of Adjusted EBITDA to evaluate and communicate its performance. While non-IFRS measures should not be construed as alternatives to IFRS measures, management believes non-IFRS measures are useful to further understand Valneva's current performance, performance trends, and financial condition.

Adjusted EBITDA is a common supplemental measure of performance used by investors and financial analysts. Management believes this measure provides additional analytical tools. Adjusted EBITDA is defined as earnings/loss for the period before income tax, finance (income)/expense, foreign exchange (gain)/loss, amortization, depreciation, and impairment.

A reconciliation of Adjusted EBITDA to net loss for the period, which is the most directly comparable IFRS measure, is set forth below:

€ in million	Twelve months ended December 31
(consolidated per IFRS)	2025	2024
Loss for the period	(115.2)	(12.2)
Add:
Income tax expense	1.1	0.8
Total Finance income	(2.6)	(2.4)
Total Finance expense	41.9	24.0
Foreign exchange (gain)/loss – net	(7.2)	3.2
Result from investments in associates	-	-
Amortization	4.8	4.9
Depreciation	16.9	14.7
Impairment	0.9	0.0
Adjusted EBITDA	(59.4)	32.9

Availability of the Full Year 2025 Financial Reports

The URD and 20-F are available on the Valneva website here. In addition, the URD and 20-F are available on the AMF website (www.amf-france.org) and SEC website (www.sec.gov), respectively.

The Company's 2025 URD includes its 2025 annual financial report, annual management report, sustainability report and the Board of Directors' corporate governance report.

The 2025 URD and 20‑F also provide a description of the Company's major agreements, including the Company's exclusive license agreement for Valneva's Clostridioides difficile vaccine candidate, VLA84, with the Austrian biotechnology company Elaris, who is developing a next-generation vaccine. This agreement includes two development‑related milestone payments as well as multiple milestone payments tied to regulatory approval and commercialization.

Additionally, the URD and 20-F describe the FDA's recent inspection of the Company's Almeida manufacturing facility in Scotland. The Company has received a response letter from the FDA, indicating that the FDA is unable to grant approval of the Almeida facility for the manufacturing of IXIARO^®. The Company is actively addressing the FDA's observations to remediate the issues identified. In the meantime, the Almeida facility is approved by the European Medicines Agency and Health Canada and operates under a manufacturers license from the UK's Medicines and Healthcare products Regulatory Agency. Therefore, IXIARO^® doses produced at this facility will be sold in these regions while products manufactured at the Manson site will be distributed in the United States.
