Explanatory notes to the condensed consolidated interim financial statements

1.    General Information
Molecular Partners AG ("Company") and its subsidiary (collectively "Molecular Partners" or "Group") is a clinical-stage biopharmaceutical company pioneering designed ankyrin repeat proteins (DARPin) candidates to treat serious diseases, with a current focus on oncology and virology. The Company was founded on November 22, 2004, and is domiciled at Wagistrasse 14, 8952 Schlieren, Canton of Zurich, Switzerland. It is subject to the provisions of the articles of association and to article 620 et seq. of the Swiss Code of Obligations, which describe the legal requirements for limited companies (“Aktiengesellschaften”).
Molecular Partners Inc. is a wholly owned subsidiary of Molecular Partners AG. Molecular Partners Inc. was incorporated in the United States in the State of Delaware on October 8, 2018. Molecular Partners Inc. is based in Cambridge, Massachusetts.
The unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2026, were approved for issuance by the Audit and Finance Committee on October 26, 2026.
The Company’s shares are listed on the SIX Swiss Exchange (Ticker: MOLN) since November 5, 2014, and on the Nasdaq Global Select Market (Ticker: MOLN) since June 16, 2021.

2.    Basis of Preparation
These unaudited condensed consolidated interim financial statements have been prepared in accordance with IAS 34 Interim Financial Reporting and should be read in conjunction with the Group's last annual consolidated financial statements as at and for the year ended December 31, 2025. They do not include all the information required for a complete set of consolidated financial statements prepared in accordance with IFRS® Accounting Standards ("IFRS") as issued by the IASB. However, selected explanatory notes are included to explain events and transactions that are significant to gain an understanding of the changes in the Group's financial position and performance since the last annual consolidated financial statements as at and for the year ended December 31, 2025.
The Board of Directors and management have assessed the Group's ability to continue as a going concern for a period of at least twelve months from the date these financial statements are authorized for issue. That assessment concluded that the going concern basis of preparation remains appropriate; however, material uncertainties exist on the current ability to raise funds and on the level of cash and cash equivalents that may cast significant doubt on the Group's ability to continue as a going concern, as described below.
Conditions and events giving rise to material uncertainty
At September 30, 2026, the Group had cash and cash equivalents and short-term financial assets of TCHF57,493. Based on the approved operating plan, existing cash resources are expected to fund operations into Q4 2027. The Company has been unable to obtain additional funding since the last issuance of shares in October 2024. As the Company historically has been dependent on raising funding through the capital markets and to a lesser extent on revenue or cost sharing arrangements, the current situation gives rise to the material uncertainty.
Management's plans and mitigating actions
Management, with oversight from the Board of Directors, has developed and is executing the following plans to address the identified conditions:



•A deepened focus on radiopharmaceuticals and streamlining of capabilities and resources resulting in a pipeline prioritization and operating cost reductions. As a result of this pipeline prioritization, the Company expects there to be no or immaterial impairment exposure. In regard to the operating cost reductions, the Company has informed on October 29, 2026, the Amt für Wirtschaft of Kanton Zürich (Office for Economic Affairs) of its intention to reduce its current workforce by no more than 55 positions, representing a potential of ~44% of all positions. Molecular Partners foresees the full implementation of these changes enacted by Q2 2027 and the reduction of costs to become fully effective early in H2 2027. See note 5.11 for further information.
•Capital raise / equity financing — ongoing efforts to secure additional funding, either through a direct issuance of shares or alternative structures.
The accounting policies set forth in the notes to those annual consolidated financial statements have been consistently applied to all periods presented, except as per below.
The condensed consolidated interim financial statements are presented in thousands of Swiss Francs (TCHF), unless stated otherwise.
The business is not subject to any seasonality. Revenues largely depend on the underlying collaboration agreements and the achievement of agreed milestones, while expenses are largely affected by the phase of the respective projects, particularly with regard to external research and development expenditures.
Due to rounding, the numbers presented in the financial statements might not precisely equal the accompanying notes.
3.    New or Revised IFRS Standards and Interpretations
A number of new or amended standards became applicable for annual periods beginning on or after January 1, 2026. These standards were assessed to not have any significant impact on the Group’s accounting policies and did not require any retrospective adjustments.
A preliminary assessment on the impact of the implementation of IFRS 18 has been performed; based on this assessment, the Company expects there to be no significant impact on the Company's overall financial statements. Based on the initial assessment the Company also expects there to be no Management defined Performance Measures or MPM’s to be reported on. IFRS 18 will not be early adopted. Possible impacts from other new or revised standards have not yet been assessed but are anticipated to be immaterial.
4.    Accounting estimates and judgments
The condensed consolidated interim financial statements have been prepared under the historical cost convention. In preparing these condensed consolidated interim financial statements, management made judgments, estimates and assumptions that not only assess the determination on operating as a going concern, based on the development of our cash balance, but also affect the application of accounting policies and the reported amounts of assets and liabilities, income and expenses. Actual results may differ from these estimates.
5.    Other explanatory notes
5.1    Other group-wide disclosures
On January 5, 2024, the Group announced it entered into a co-development agreement with Orano Med to co-develop 212Pb-based Radio Darpin Therapies (RDT). Under the terms of the co-development agreement, Molecular Partners previously disclosed RDT target DLL3 (delta-like ligand 3) is included in



the collaboration with Orano Med. Both companies agree to share the cost of preclinical and clinical development with additional commitments to supply their respective materials.
The cost sharing in the first nine months of 2026 resulted in a reimbursement of expenses by Orano Med of TCHF710 (First nine months of 2025: TCHF2,030) and for the three months ended September 30, 2026: TCHF285 (Three months ended September 30, 2025: TCHF633) reported under research and development expenses.

5.2    Share capital
As of September 30, 2026, the issued share capital of the Company amounted to CHF 4,037,464 divided into 40,374,641 fully paid registered shares, inclusive of 2,039,227 treasury shares (December 31, 2025: CHF 4,037,464 divided into 40,374,641 shares, of which 2,962,973 were treasury shares).

5.3    Dividends
The Group has paid no dividends since its inception and does not anticipate paying dividends in the foreseeable future.

5.4    Share-based compensation
As of September 30, 2026, a total of 3,253,411 PSUs and 586,723 Restricted Share Units ("RSUs") were outstanding (as of December 31, 2025, a total of 2,918,458 PSUs and 504,543 RSUs were outstanding). The changes in the number of share-based awards (PSUs and RSUs) outstanding during the nine month period ended September 30, 2026, is as follows:

The share-based compensation costs recognized during the nine months ended September 30, 2026, amounted to TCHF 2,784 (TCHF 3,446 for the nine months ended September 30, 2025). For the three months ended September 30, 2026, the share-based compensation costs amounted to TCHF 941 (TCHF 1,076 for the three months ended September 30, 2025).

5.6    Income taxes
The Group has in recent years reported operating losses, with the exception of the year ended December 31, 2022, that resulted in a tax loss carry-forward in Switzerland of TCHF 252,980 as of December 31, 2025. No deferred tax assets have been recognized for these tax loss carry forwards, because it is not probable that such loss carry forwards can be utilized in the foreseeable future. In addition, no deferred tax positions were recognized on other deductible temporary differences (e.g., pension liabilities under IAS 19) due to the significant tax loss carry forwards.

5.8    Other Comprehensive result
In order to recognize remeasurements of the net defined benefit obligation in the period in which they arise, the Group utilizes its independent actuaries to update the calculation of the defined benefit obligation and plan assets at each reporting date. The primary components of the remeasurement as of and for the nine month period ended September 30, 2026, relate to an increase in the value of the assets held under the defined benefit plan and changes to demographic assumptions.
5.9    Related parties
The Group did not enter into any related party transactions in the interim periods presented.
5.10    Restructuring expense
For the nine months ended September 30, 2026 no restructuring expense was recognized. For the nine months ended September 30, 2025, the Group recognized TCHF 2,733 as expenses related to the restructuring initiated June 10, 2025. The restructuring charges primarily consisted of personnel related cost.
5.11    Events after the balance sheet date
On October 29, 2026 the Company has informed the Amt für Wirtschaft of Kanton Zürich (Office for Economic Affairs) of its intention, as part of a company restructuring, to reduce its current workforce by no more than 55 positions, representing a potential of ~44% of all positions. In accordance with Swiss employment law, a consultation process with employees has been initiated. Upon completion of the consultation process, the Company will offer affected employees support. Molecular Partners foresees the full implementation of these changes enacted by Q2 2027 and the reduction of costs to become fully effective early in H2 2027. The financial impact from the restructuring is not estimable at this time, as the Company is still assessing the specifics of affected employees.



Other than the workforce reduction described above, no other events occurred between the balance sheet date and the date on which these condensed consolidated interim financial statements were approved for issuance by the Board of Directors that would require adjustment to these condensed consolidated interim financial statements or disclosure under this section.
