ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., August 26, 2024 (GLOBE NEWSWIRE)Ad hoc announcement pursuant to Art. 53 LR: Molecular Partners AG (SIX: MOLN; NASDAQ: MOLN), a clinical-stage biotech company developing a new class of custom-built protein drugs known as DARPin therapeutics ("Molecular Partners" or the "Company"), today announced corporate highlights and unaudited financial results for the first half-year of 2024.

“In the first half of 2024, we made substantial progress with our Radio-DARPin Therapy (RDT) platform. We nominated the first RDT candidate, MP0712 targeting DLL3, and we look forward to bringing it to patients in 2025 with our partner Orano Med, the leader in the 212Pb field. With them, we entered into a strategic collaboration earlier this year, to access and leverage their supply and manufacturing capabilities, as well as clinical experience, with radiopharmaceuticals, to co-develop Radio-DARPin Therapeutics together,” said Patrick Amstutz, Ph.D., Molecular Partners’ Chief Executive Officer. “Additionally, we progressed our immune cell engagers, including the cKit Switch-DARPin MP0621 into pre-clinical studies, and progressed MP0533 in AML to the top planned dose, seeing initial clinical responses and now testing dose intensification.”


Research & Development Highlights

Radio-DARPin Therapy (RDT) Platform and MP0712
Molecular Partners has leveraged the intrinsic properties of DARPins, such as small size, high affinity and specificity, to engineer Radio-DARPins as ideal vector candidates for radiopharmaceutical therapeutics and to create a Radio-DARPin Therapy (RDT) platform amenable to a broad range of tumor targets. Historically, small protein-based vectors faced challenges with kidney accumulation and toxicity, as well as suboptimal tumor uptake. Molecular Partners’ RDT platform addresses these limitations with its half-life extension technologies and surface engineering approaches, while preserving the advantages of the small protein format.

Throughout H1 2024, Molecular Partners has continued to demonstrate the RDT platform's ability to deliver on its intended design. The Company has engaged with scientific experts in radiopharmaceutical innovation, as well as investor and clinical communities to build awareness of the unique offering of Radio-DARPins and to identify opportunities for potential RDT portfolio growth.

In January 2024, Molecular Partners entered into a strategic collaboration with Orano Med to co-develop 212Pb-based RDTs for patients with solid tumors. The partnership combines Molecular Partners' leadership in DARPins, as a highly differentiated modality for tumor-targeted delivery of radioisotopes,


https://cdn.kscope.io/4312621bb2f479e25d234ca5e1ee2679-image_0a.jpg
with Orano Med’s leading expertise and capabilities in Targeted Alpha Therapy to further advance the RDT platform and expand Molecular Partners’ RDT portfolio. 212Pb represents the next generation of targeted alpha therapies, with a selective, safe, and potent profile in patients: in addition to virtually endless supply of starting material, Orano Med has established robust and independent supply and manufacturing capabilities required for seamless delivery of targeted alpha therapies to clinical sites.

In June 2024, Molecular Partners nominated MP0712 as its first RDT candidate, a 212Pb-based DLL3-targeting RDT in its co-development program with Orano Med. The supporting preclinical data were presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2024 Annual Meeting which took place in Toronto, Canada.

DLL3 is a priority target for radiopharmaceutical therapy based on its abundant expression in over 85% small cell lung cancer (SCLC) patients and other aggressive neuroendocrine tumors, while its expression in healthy tissues is low. SCLC is an aggressive form of lung cancer, with a poor five-year survival prognosis and a high unmet need for patients.

The data presented at SNMMI provide strong support for the clinical development of MP0712 in SCLC and other DLL3-expressing neuroendocrine tumors. In vivo data demonstrated strong and homogeneous tumor uptake, as well as substantial and durable inhibition of tumor growth at clinically relevant doses. Furthermore, the in vivo data suggested a favorable preclinical safety profile and support MP0712's potential for clinical use. Achieving favorable tumor to kidney ratios and biodistribution are key design objectives for this program. In both areas MP0712 performed well in mouse xenograft tumor models; tumor to kidney ratios over two were observed, and close to 60% of the injected dose per gram of tissue was detectable in the tumor.

The replicable learnings from the development and optimization of MP0712, as well as additional RDT platform improvements, are being taken forward to the broader RDT portfolio. Molecular Partners will present additional data in an oral presentation at the 2024 Congress of the European Association of Nuclear Medicine (EANM) in October 2024, and plans to initiate a first-in-human clinical trial of MP0712 in 2025.

In addition to the above updates, Molecular Partners continued to progress its RDT portfolio of projects in partnership with Novartis and is evaluating additional targets for RDT programs.

MP0533
MP0533, a novel tetra-specific T cell-engaging DARPin, is currently being evaluated in a Phase 1/2a clinical trial for patients with relapsed/refractory acute myeloid leukemia (r/r AML) and myelodysplastic syndrome/AML (MDS/AML) (ClinicalTrials.gov: NCT05673057). The mechanism of action of MP0533 is designed to preferentially kill AML cells (blasts, leukemic progenitor and stem cells) that express any combination of the three cell surface antigens CD33, CD123, and CD70, while sparing healthy cells, which tend to express only one or none of these targets. The immune activation against the malignant cells is achieved through CD3-mediated T cell-engagement.

In April 2024, comprehensive preclinical data supporting MP0533’s proposed unique mechanism of action for the treatment of AML was published in Cancer Immunology Research (https://doi.org/10.1158/2326-6066.CIR-23-0692), a journal of the American Association for Cancer Research.

In the ongoing Phase 1/2a clinical trial, as of 29 July 2024, MP0533 has demonstrated an acceptable safety profile with the majority of adverse events reported being infusion-related reactions and cytokine release syndrome. Four clinical responses have been observed among the 28 patients across dosing regimens (DR) 1–6. These included a complete response in DR 4 and a morphologic leukemia-free state in three patients, one each in DRs 3, 5 and 6. Furthermore, an encouraging trend in bone marrow blast cell reductions was observed as of the data cut-off date; 7 of 26 evaluable patients and 5 of 11 patients with low disease burden at baseline (blasts <20%) displayed a blast reduction over 50%.

At present, data are being collected for DR7 and dose escalation continues with DR 8 open. Based on the observed safety profile and encouraging initial antitumor activity data, and following discussion with treating physicians and key opinion leaders, Molecular Partners is amending the protocol to further


https://cdn.kscope.io/4312621bb2f479e25d234ca5e1ee2679-image_0a.jpg
increase dosing and improve the exposure profile of MP0533. The Company's aim is to achieve higher response rates, as well as improved depth and duration of responses in r/r AML patients. Molecular Partners plans to present a clinical update on the program in H2 2024, and on the amended dosing scheme for MP0533 in 2025.

Switch-DARPin Platform and first candidate MP0621
The Switch-DARPin platform represents a novel innovative DARPin-based approach by Molecular Partners that provides a logic-gated “on/off” function (the “Switch”) to multispecific DARPin candidates, allowing target activation only in the presence of a defined set of antigens. The goal is conditional activation of a targeted immune response. The first Switch-DARPin program, MP0621 (cKit x CD16a x CD47), was introduced in January 2024 and is designed to induce killing of hematopoietic stem cells as a next-generation conditioning regimen. Molecular Partners’ intends to extend access to potentially curative HSCT for more patients with AML as well as those with other hematologic malignancies or genetic diseases requiring HSCT.

In June 2024, the Company presented preclinical proof-of-concept data from MP0621 at the European Hematology Association (EHA) 2024 Hybrid Congress which took place in Madrid, Spain. The safety, efficacy and pharmacokinetic data supported MP0621’s ability to selectively kill cKit positive cells and conditionally block the immunosuppressive protein CD47, with limited systemic side effects.

Crucially, these preclinical data also validated the Switch-DARPin concept, demonstrating that a logic-gated immune activation with a reversible switch can be achieved with a DARPin design. This provides another novel DARPin approach for conditional activation of anticancer immunotherapies and its utilization to locally engage immune-modulating targets not amenable to other treatment modalities. Further preclinical studies are ongoing with updates for the MP0621 program planned for H2 2024.

MP0317
MP0317 is a CD40 agonist designed to activate immune cells specifically within the tumor microenvironment (TME) by anchoring to fibroblast activation protein (FAP) which is expressed in high amounts around tumors. This tumor-localized approach has the potential to deliver greater efficacy with fewer side effects compared to systemic CD40-targeting therapies.

In June 2024, the Company presented positive data from its completed Phase 1 dose-escalation clinical trial of MP0317 at the American Society of Clinical Oncology (ASCO) Annual Meeting 2024 which took place in Chicago, IL, USA.

The final analysis included 46 patients with advanced solid tumors and confirmed earlier reported interim results. MP0317 displayed a favorable and manageable safety profile across all nine planned dosing cohorts (0.03–10 mg/kg) administered intravenously weekly or every 3 weeks with only one patient experiencing a dose-limiting toxicity (transient asymptomatic grade 3 elevation of liver enzymes). The most frequently observed adverse reactions were fatigue and lower grade infusion-related reactions (grade 1–2). MP0317 treatment resulted in target occupancy in tumor biopsies with evidence of TME remodeling. In terms of clinical response, one patient achieved an unconfirmed partial response and stable disease was observed in 14 additional patients.

The positive data support further clinical evaluation of MP0317 in combination with complementary anticancer therapies and demonstrated the ability of the DARPin design to deliver on a targeted, tumor-localized CD40 activation mechanism. Molecular Partners is in discussion with leading academic centers regarding potential investigator-initiated combination trials.

About DARPin Therapeutics
DARPin (Designed Ankyrin Repeat Protein) therapeutics are a new class of custom-built protein drugs based on natural binding proteins that open new dimensions of multi-functionality and multi-target specificity in drug design. The flexible architecture, intrinsic potential for high affinity and specificity, small size and high stability of DARPins offer benefits to drug design over other currently available protein-based therapeutics. DARPin candidates can be radically simple, with a single DARPin unit acting as the delivery vector to a specific target; or multispecific, with the possibility of engaging more than five targets, and combining multiple and conditional functionalities in a unique DARPin drug candidate. The DARPin platform is designed to be a rapid and cost-effective drug discovery engine, producing drug candidates with optimized properties and high production yields. DARPin therapeutics have been clinically validated across several therapeutic areas and developed through to the registrational stage.

Exhibit 99.2
Business Update
Molecular Partners AG (SIX: MOLN; NASDAQ: MOLN), a clinical-stage biotech company developing a new class of custom-built protein drugs known as DARPin therapeutics ("Molecular Partners" or the "Company"), today announced corporate highlights and unaudited financial results for the first half-year of 2024.

“In the first half of 2024, we made substantial progress with our Radio-DARPin Therapy (RDT) platform. We nominated the first RDT candidate, MP0712 targeting DLL3, and we look forward to bringing it to patients in 2025 with our partner Orano Med, the leader in the 212Pb field. With them, we entered into a strategic collaboration earlier this year, to access and leverage their supply and manufacturing capabilities, as well as clinical experience, with radiopharmaceuticals, to co-develop Radio-DARPin Therapeutics together,” said Patrick Amstutz, Ph.D., Molecular Partners’ Chief Executive Officer. “Additionally, we progressed our immune cell engagers, including the cKit Switch-DARPin MP0621 into pre-clinical studies, and progressed MP0533 in AML to the top planned dose, seeing initial clinical responses and now testing dose intensification.”


Research & Development Highlights
Radio-DARPin Therapy (RDT) Platform and MP0712
Molecular Partners has leveraged the intrinsic properties of DARPins, such as small size, high affinity and specificity, to engineer Radio-DARPins as ideal vector candidates for radiopharmaceutical therapeutics and to create a Radio-DARPin Therapy (RDT) platform amenable to a broad range of tumor targets. Historically, small protein-based vectors faced challenges with kidney accumulation and toxicity, as well as suboptimal tumor uptake. Molecular Partners’ RDT platform addresses these limitations with its half-life extension technologies and surface engineering approaches, while preserving the advantages of the small protein format.

Throughout H1 2024, Molecular Partners has continued to demonstrate the RDT platform's ability to deliver on its intended design. The Company has engaged with scientific experts in radiopharmaceutical innovation, as well as investor and clinical communities to build awareness of the unique offering of Radio-DARPins and to identify opportunities for potential RDT portfolio growth.

In January 2024, Molecular Partners entered into a strategic collaboration with Orano Med to co-develop 212Pb-based RDTs for patients with solid tumors. The partnership combines Molecular Partners' leadership in DARPins, as a highly differentiated modality for tumor-targeted delivery of radioisotopes, with Orano Med’s leading expertise and capabilities in Targeted Alpha Therapy to further advance the RDT platform and expand Molecular Partners’ RDT portfolio. 212Pb represents the next generation of targeted alpha therapies, with a selective, safe, and potent profile in patients: in addition to virtually endless supply of starting material, Orano Med has established robust and independent supply and manufacturing capabilities required for seamless delivery of targeted alpha therapies to clinical sites.

In June 2024, Molecular Partners nominated MP0712 as its first RDT candidate, a 212Pb-based DLL3-targeting RDT in its co-development program with Orano Med. The supporting preclinical data were presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2024 Annual Meeting which took place in Toronto, Canada.

DLL3 is a priority target for radiopharmaceutical therapy based on its abundant expression in over 85% small cell lung cancer (SCLC) patients and other aggressive neuroendocrine tumors, while its
1


expression in healthy tissues is low. SCLC is an aggressive form of lung cancer, with a poor five-year survival prognosis and a high unmet need for patients.

The data presented at SNMMI provide strong support for the clinical development of MP0712 in SCLC and other DLL3-expressing neuroendocrine tumors. In vivo data demonstrated strong and homogeneous tumor uptake, as well as substantial and durable inhibition of tumor growth at clinically relevant doses. Furthermore, the in vivo data suggested a favorable preclinical safety profile and support MP0712's potential for clinical use. Achieving favorable tumor to kidney ratios and biodistribution are key design objectives for this program. In both areas MP0712 performed well in mouse xenograft tumor models; tumor to kidney ratios over two were observed, and close to 60% of the injected dose per gram of tissue was detectable in the tumor.

The replicable learnings from the development and optimization of MP0712, as well as additional RDT platform improvements, are being taken forward to the broader RDT portfolio. Molecular Partners will present additional data in an oral presentation at the 2024 Congress of the European Association of Nuclear Medicine (EANM) in October 2024, and plans to initiate a first-in-human clinical trial of MP0712 in 2025.

In addition to the above updates, Molecular Partners continued to progress its RDT portfolio of projects in partnership with Novartis and is evaluating additional targets for RDT programs.

MP0533
MP0533, a novel tetra-specific T cell-engaging DARPin, is currently being evaluated in a Phase 1/2a clinical trial for patients with relapsed/refractory acute myeloid leukemia (r/r AML) and myelodysplastic syndrome/AML (MDS/AML) (ClinicalTrials.gov: NCT05673057). The mechanism of action of MP0533 is designed to preferentially kill AML cells (blasts, leukemic progenitor and stem cells) that express any combination of the three cell surface antigens CD33, CD123, and CD70, while sparing healthy cells, which tend to express only one or none of these targets. The immune activation against the malignant cells is achieved through CD3-mediated T cell-engagement.

In April 2024, comprehensive preclinical data supporting MP0533’s proposed unique mechanism of action for the treatment of AML was published in Cancer Immunology Research (https://doi.org/10.1158/2326-6066.CIR-23-0692), a journal of the American Association for Cancer Research.

In the ongoing Phase 1/2a clinical trial, as of 29 July 2024, MP0533 has demonstrated an acceptable safety profile with the majority of adverse events reported being infusion-related reactions and cytokine release syndrome. Four clinical responses have been observed among the 28 patients across dosing regimens (DR) 1–6. These included a complete response in DR 4 and a morphologic leukemia-free state in three patients, one each in DRs 3, 5 and 6. Furthermore, an encouraging trend in bone marrow blast cell reductions was observed as of the data cut-off date; 7 of 26 evaluable patients and 5 of 11 patients with low disease burden at baseline (blasts <20%) displayed a blast reduction over 50%.

At present, data are being collected for DR7 and dose escalation continues with DR 8 open. Based on the observed safety profile and encouraging initial antitumor activity data, and following discussion with treating physicians and key opinion leaders, Molecular Partners is amending the protocol to further increase dosing and improve the exposure profile of MP0533. The Company's aim is to achieve higher response rates, as well as improved depth and duration of responses in r/r AML patients. Molecular Partners plans to present a clinical update on the program in H2 2024, and on the amended dosing scheme for MP0533 in 2025.

Switch-DARPin Platform and first candidate MP0621
The Switch-DARPin platform represents a novel innovative DARPin-based approach by Molecular Partners that provides a logic-gated “on/off” function (the “Switch”) to multispecific DARPin candidates, allowing target activation only in the presence of a defined set of antigens. The goal is conditional activation of a targeted immune response. The first Switch-DARPin program, MP0621 (cKit x CD16a x CD47), was introduced in January 2024 and is designed to induce killing of hematopoietic stem cells as a next-generation conditioning regimen. Molecular Partners’ intends to extend access to potentially curative HSCT for more patients with AML as well as those with other hematologic malignancies or genetic diseases requiring HSCT.

In June 2024, the Company presented preclinical proof-of-concept data from MP0621 at the European Hematology Association (EHA) 2024 Hybrid Congress which took place in Madrid, Spain. The safety, efficacy and pharmacokinetic data supported MP0621’s ability to selectively kill cKit positive cells and conditionally block the immunosuppressive protein CD47, with limited systemic side effects.

Crucially, these preclinical data also validated the Switch-DARPin concept, demonstrating that a logic-gated immune activation with a reversible switch can be achieved with a DARPin design. This provides another novel DARPin approach for conditional activation of anticancer immunotherapies and its utilization to locally engage immune-modulating targets not amenable to other treatment modalities. Further preclinical studies are ongoing with updates for the MP0621 program planned for H2 2024.

MP0317
MP0317 is a CD40 agonist designed to activate immune cells specifically within the tumor microenvironment (TME) by anchoring to fibroblast activation protein (FAP) which is expressed in high amounts around tumors. This tumor-localized approach has the potential to deliver greater efficacy with fewer side effects compared to systemic CD40-targeting therapies.

In June 2024, the Company presented positive data from its completed Phase 1 dose-escalation clinical trial of MP0317 at the American Society of Clinical Oncology (ASCO) Annual Meeting 2024 which took place in Chicago, IL, USA.

The final analysis included 46 patients with advanced solid tumors and confirmed earlier reported interim results. MP0317 displayed a favorable and manageable safety profile across all nine planned dosing cohorts (0.03–10 mg/kg) administered intravenously weekly or every 3 weeks with only one patient experiencing a dose-limiting toxicity (transient asymptomatic grade 3 elevation of liver enzymes). The most frequently observed adverse reactions were fatigue and lower grade infusion-related reactions (grade 1–2). MP0317 treatment resulted in target occupancy in tumor biopsies with evidence of TME remodeling. In terms of clinical response, one patient achieved an unconfirmed partial response and stable disease was observed in 14 additional patients.

The positive data support further clinical evaluation of MP0317 in combination with complementary anticancer therapies and demonstrated the ability of the DARPin design to deliver on a targeted, tumor-localized CD40 activation mechanism. Molecular Partners is in discussion with leading academic centers regarding potential investigator-initiated combination trials.

Financial highlights
Over the course of 2024, the Group continued to invest in its clinical and preclinical programs as well as in research and development in order to progress its portfolio of DARPin candidates towards value-creating milestones.
The strong balance sheet continues to provide our Group with financial flexibility and a forecasted cash runway into 2027 beyond the envisaged key value inflection points expected to be captured until then.
Molecular Partners’ broad pipeline across multiple indications in oncology, its collaborations with pharma companies, and its financial position, all combine to provide our Group a robust position within the biotech sector. The Group continues to employ its financial and human resources into the evolution of its proprietary DARPin technology, the progression of innovative programs as well as the advancement of its pipeline of proprietary and outlicensed drug candidates in clinical development, targeting high-value indications.
Revenues
In H1 2024, the Group recognized total revenues and other income of CHF 4.3 million (2023: CHF 3.5 million). The revenue in the first six months of 2024 and 2023 was solely attributable to the Group's collaboration with Novartis.
As of June 30, 2024 the Group has CHF 0.6 million of contract liabilities under the Novartis collaboration agreement. This contract liability is expected to be recognized as revenue in the current year as the Group performs its collaboration activities.
Operating expenses (incl. depreciation and amortization)
The Group’s operating expenses consist primarily of costs associated with research, preclinical and clinical testing, personnel-related costs and, to a lesser extent, facility expenses, professional fees for legal, tax, audit and strategic purposes, administrative expenses and depreciation of property, plant and equipment.
Overall, total operating expenses increased by CHF 1.6 million (5%) to CHF 36.1 million in H1 2024 (compared to CHF 34.5 million in H1 2023). The two major expense categories were personnel expenses of CHF 20.2 million (56% of total operating expenses) and research and development projects related costs totaling CHF 10.5 million (29% of total operating expenses).
Total R&D expenses in H1 2024 increased by CHF 2.9 million (12%) to CHF 27.2 million (H1 2023: CHF 24.3 million), mainly due to higher costs associated with manufacturing and clinical activities for MP0533, during 2024 as compared to 2023.
Total SG&A expenses in H1 2024 went down by CHF 1.2 million (12%) to CHF 8.9 million (H1 2023: CHF 10.2 million), mainly due to an decrease in director and officers insurance and professional fees.
As of June 30, 2024, the Group had 161.9 full-time employees (FTEs) on its payroll, including 135.7 FTEs (84%) in R&D and 26.2 FTEs (16%) in SG&A.

Operating result
In the first six months of 2024, the Group generated an operating loss of CHF 31.8 million (compared to an operating profit of CHF 31.0 million in the same period in 2023).
Financial income and expenses
In the first six months of 2024, Molecular Partners recorded a net financial gain of CHF 5.4 million, compared to a net financial gain of CHF 0.2 million in the same period in 2023.
The financial income amounted to CHF 5.4 million, is driven by income generated from interest on the Group's cash balances. The Group does not hedge for translation risks as it pursues a stringent natural hedging policy by optimizing the matching of cash in/out flows in the respective currencies.
Income and deferred taxes
Molecular Partners AG did not have to pay or accrue any income taxes in the reporting periods. Future taxable income in Switzerland will be subject to federal, cantonal and communal income taxes. The Company’s applicable income tax rate in Switzerland is 19.3%.
Net result
In H1 2024, the Group recorded a net loss of CHF 26.4 million (H1 2023: CHF 30.8 million net loss).
Balance sheet and capital resources
As of June 30, 2024, the Group’s position on cash and cash equivalents plus short-term time deposits decreased by CHF 27.8 million compared to year-end 2023 to CHF 159.1 million (or 93% of the total assets).
Compared to year-end 2023, the total shareholders’ equity position decreased by CHF 20.9 million to CHF 155.6 million as of June 30, 2024 (December 31, 2023: CHF 176.4 million). The Group’s balance sheet continued to be debt-free throughout H1 2024.
Liabilities in the balance sheet are primarily comprised of contract liabilities, trade payables and accrued expenses from our operations as well as pension liabilities as per IAS19. Total liabilities as of June 30, 2024 amount to CHF 15.0 million (December 31, 2023: CHF 21.9 million).

Cash flow statement
In the first six months of 2024, Molecular Partners recorded a net cash outflow from operations of CHF 32.8 million, compared to the net cash outflow from operations of CHF 29.8 million in the same period in 2023.
Cash inflow from investing activities during the first six months of 2024 was CHF 30.8 million, compared to a CHF 7.4 million cash inflow in the same period of 2023. The cash flows from investing activities are largely driven by the shift of cash into short-term time deposits and vice versa. During the first six months of 2024 a CHF 0.3 million outflow was recorded for capital expenditures in equipment and intangible assets.
Net cash outflow from financing activities in the first six months of 2024 was CHF 0.6 million. Overall, the cash flow activities resulted in a net decrease of the Group’s total cash and cash equivalents balance of CHF 1.6 million from CHF 67.3 million at the end of 2023 to CHF 65.7 million as per June 30, 2024.
Financial risk management
The Group is developing several products and is currently not generating a constant revenue stream. At present, the lack of consistent positive operating cash flow may expose the Group to financing risks in the medium term. Risk management is carried out centrally under policies approved by the Board of Directors. Furthermore, the Group manages financial risks such as foreign exchange risk and liquidity.
Molecular Partners conducts its activities primarily in Switzerland, EU and U.S. As a result, the Group is exposed to a variety of financial risks, such as foreign exchange rate risk, credit risk, liquidity risk, cash flow and interest rate risk. The Group’s overall financial risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the financial performance of the Group. The Group is not exposed to market price development as it has no saleable products.
The following is a summary of how we manage and mitigate the key financial risks:
Foreign exchange risk: In order to reduce its foreign exchange exposure, Molecular Partners may enter into currency contracts (forwards and options) with selected high-quality financial institutions to hedge against foreign currency exchange rate risks. The Group’s primary exposure to financial risk is due to fluctuation of exchange rates between CHF, EUR, and USD. The Group’s hedging policy is (1) to maximize natural hedging by matching expected future cash flows in the different currencies and (2) if markets conditions allow, to consider hedging certain of the remaining expected net currency exposure as the need arises. However, due to market volatilities and uncertainties in the cash flows, a 100% hedging of the currency exposure is impossible or not appropriate. Molecular Partners does not engage in speculative transactions.
Interest rate risk: Molecular Partners earns interest income or may pay negative interest on cash and cash equivalents and its profit and loss may be influenced by changes in market interest rates. The Group is investing a portion of its cash balances in short-term time deposits in line with its treasury guidelines.
Credit risk: The maximum credit risk on financial instruments corresponds to the carrying amounts of the Group’s cash and cash equivalents and receivables. The Group has not entered into any guarantees or similar obligations that would increase the risk over and above
10


the carrying amounts. All cash and cash equivalents are held with three major Swiss banks with ratings between A and AAA as per Standard & Poor’s. The Group enters into partnerships with partners which have the appropriate credit history and a commitment to ethical business practices. Other receivables with credit risk mainly include interest receivables.
Liquidity risk: Based on the Group’s Business Plan 2024-2028, management estimates that the Group is financed into 2027 .

Financial Outlook 2024
For the full year 2024, at constant exchange rates, the Group expects total expenses of CHF 65-75 million (previously estimated at CHF 70 - 80 million), of which approximately CHF 8 million will be non-cash effective costs for share-based payments, IFRS pension accounting and depreciation.
With CHF 159 million in cash and cash equivalents plus short-term time deposits and no debt as of June 30, 2024, Molecular Partners expects to be funded into 2027, excluding any potential receipts from R&D partners.

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 six months ended June 30, 2024 were approved for issuance by the Board of Directors on August 26, 2024.
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, 2023. They do not include all the information required for a complete set of consolidated financial statements prepared in accordance with 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, 2023.
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 alliance contracts 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, 2024. These standards are not expected to have any significant impact on the Group’s accounting policies and did not require any retrospective adjustments.

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 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    Revenue and 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 Partner’s previously disclosed RDT target DLL3 (delta-like ligand 3) will be included in the collaboration with Orano Med. Both companies are developing additional radioligand therapy candidates in partnership with other companies, with Molecular Partners having announced its first collaboration with Novartis in December 2021.
Molecular Partners maintains the option to explore DLL3 for targeted therapy outside of the radiotherapy space. Both companies agree to share the cost of preclinical and clinical development with additional commitments to supply their respective materials.
On December 14, 2021, the Group entered into a License and Collaboration Agreement with Novartis to develop DARPin-conjugated radioligand therapeutic candidates for oncology. The Group is able to recharge Novartis its employee related expenses associated with the research activities. During the six months ended June 30, 2024, the Group recognized as revenue an amount of TCHF 541 in relation to this recharge (six months ended June 30, 2023: TCHF 678). During the three months ended June 30, 2024, the Group recognized as revenue an amount of TCHF 230 in relation to this recharge (three months ended June 30, 2023: TCHF 292).
As part of the same agreement, the Group received in January 2022 an upfront fee of USD 20 million (CHF 18.6 million). Revenue related to the upfront payment is recognized over time in line with the progress made over the duration of the contractually agreed research plan.
During the six months ended June 30, 2024, the Group recognized as revenue an amount of TCHF 3,748 (six months ended June 30, 2023: TCHF 2,787) related to the upfront payment received in January 2022. During the three months ended June 30, 2024, the Group recognized as revenue an amount of TCHF 1,321 (three months ended June 30, 2023: TCHF 123) in relation to the same upfront payment.

5.7    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 144,483 as of December 31, 2023. 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.

5.9    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 component of the remeasurement as of and for the six month period ended June 30, 2024, relates to an increase in the funding status of our main pension provider.
5.10    Related parties
The Group did not enter into any related party transactions in the interim periods presented.
5.11    Putative Class Action
On July 12, 2022, a putative class action complaint was filed in the U.S. District Court for the Southern District of New York against the Company, its directors, and certain of its executive officers. On May 23, 2023, an amended complaint was filed. The amended complaint alleged that the defendants violated federal securities laws by, among other things, making misrepresentations and omissions regarding its product candidate MP0310 and an associated licensing agreement. The amended complaint sought among others unspecified compensatory damages on behalf of persons and/or entities which purchased the Company's American Depositary Shares (ADSs) pursuant to certain offering documents issued in connection with the Company's initial public offering of ADSs. The Company and named individual defendants moved to dismiss the amended complaint on July 24, 2023. On February 5, 2024, the court dismissed the amended complaint without prejudice. On February 29, 2024, the court ordered the case closed.
5.12    Events after the balance sheet date
No 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.

Independent Auditors’ Report on Review of Condensed Consolidated Interim Financial Information to the Board of Directors of Molecular Partners AG, Schlieren

Introduction
We have been engaged to review the accompanying condensed consolidated interim statement of financial position of Molecular Partners AG as at June 30, 2024 and the related condensed consolidated interim statements of comprehensive loss for the six and three-months periods ended June 30, 2024, the related condensed consolidated interim cash flow statement and statement of changes in equity for the six-month period then ended, and selected explanatory notes (the condensed consolidated interim financial information). The Board of Directors is responsible for the preparation and presentation of this condensed consolidated interim financial information in accordance with International Accounting Standard 34 Interim Financial Reporting. Our responsibility is to express a conclusion on this condensed consolidated interim financial information based on our review.

Scope of Review
We conducted our review in accordance with the International Standard on Review Engagements 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion
Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial information as at and for the six and three-months periods ended June 30, 2024 is not prepared, in all material respects, in accordance with International Accounting Standard 34 Interim Financial Reporting.
