Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties, including those described in the section titled “Special Note Regarding Forward Looking Statements.” Our actual results and the timing of selected events could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those set forth under the section titled “Risk Factors” included elsewhere in this Annual Report.

Overview

We are a biotechnology company developing a portfolio of novel and proprietary MGDs. MGDs are small molecule drugs that employ the body’s natural protein destruction mechanisms to selectively degrade therapeutically relevant proteins. MGDs work by inducing the engagement of defined surfaces identified on target proteins by an E3 ligase, such as cereblon. We have developed a proprietary and industry-leading protein degradation discovery engine, called QuEENTM, to enable our unique, target-centric, MGD discovery and development process and our rational design of MGD products. We believe our small molecule MGDs may give us significant advantages over existing therapeutic modalities, including other protein degradation approaches. We prioritize our product development on therapeutic targets backed by strong biological and genetic rationale with the goal of discovering and developing novel medicines.

Monte Rosa Therapeutics AG, a Swiss operating company, was incorporated under the laws of Switzerland in April 2018. Monte Rosa Therapeutics, Inc. was incorporated in Delaware in November 2019. In 2020, through a common control reorganization, Monte Rosa Therapeutics, Inc. acquired the net assets and shareholding of Monte Rosa Therapeutics AG. Monte Rosa Therapeutics, Inc. includes wholly owned subsidiaries Monte Rosa Therapeutics AG and Monte Rosa Securities Corporation. We are headquartered in Boston, Massachusetts with research operations in both Boston and Basel, Switzerland.

Liquidity

To date, we have financed our operations primarily through the issuance and sale of convertible promissory notes, convertible preferred stock, public offerings of our common stock or warrants to purchase common stock, registered direct offerings, and through our collaboration agreements. From our inception through the date hereof, we raised an aggregate of $834.8 million of gross proceeds from such transactions. Since inception, we have had significant operating losses. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures and, to a lesser extent, general and administrative expenditures. Our net loss was $72.7 million and $135.4 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, we had an accumulated deficit of $438.6 million and $377.0 million of cash, cash equivalents, restricted cash, and marketable securities.

Impact of global economic and political developments

The development of our product candidates could be disrupted and materially adversely affected in the future by global economic or political developments. In addition, economic uncertainty in global markets caused by political instability and conflict, and economic challenges caused by global pandemics or other public health events, may lead to market disruptions, including significant volatility in commodity prices, credit and capital market instability and supply chain interruptions. Our business, financial condition and results of operations could be materially and adversely affected by negative impacts on the global economy and capital markets resulting from these global economic conditions, particularly if such conditions are prolonged or worsen.

Components of operating results

Collaboration revenue

Collaboration revenue represents amounts earned from our collaboration and license agreements with Roche and Novartis. We expect that our revenue for the next several years will be dervied primarily through our current collaboration and license agreements and any additional collaborations that we may enter into in the future.

Roche agreement

On October 16, 2023, Monte Rosa AG entered into a Collaboration and License Agreement with Roche Basel and Roche US, and together with Roche Basel, Roche, or the “Roche Agreement”. Pursuant to the Roche Agreement, the parties will seek to identify and MGDs against cancer or neurological disease targets using our proprietary drug discovery platform for an initial set of targets in oncology and neuroscience selected by Roche, with Roche having an option to expand the collaboration with an additional set of targets under certain conditions, each target being subject to certain substitution rights owned by Roche. We will lead preclinical discovery and research activities until a defined point. Upon such point, Roche gains the right to exclusively pursue further preclinical and clinical development activities.

Under the Agreement, Roche will have a worldwide, exclusive license under patents and know-how controlled by us to develop and commercialize products directed to applicable targets. The research collaboration activities governed by the Agreement will be overseen by a joint research committee.

Under the terms of the agreement, we received an upfront payment of $50 million, and are eligible to receive future preclinical, clinical, commercial and sales milestone payments that could exceed $2 billion, including up to $172 million for achieving preclinical milestones. Roche has an option to expand the collaboration with an additional set of targets under certain conditions. For the optional additional targets, we are entitled to receive from Roche an upfront payment of up to $28 million, and potential preclinical, clinical, commercial, and sales milestones exceeding $1 billion. We are also eligible to receive tiered royalties ranging from high-single-digit percent to low-teens percent on any products that are commercialized by Roche as a result of the collaboration.

Unless earlier terminated, the Agreement will remain in effect for each product licensed under the Agreement until expiration of the royalty term for the applicable product. The parties have included customary termination provisions in the agreement, allowing termination of the Agreement in its entirety, on a country-by-country or a target-by-target basis.

Novartis agreement

On October 25, 2024, Monte Rosa AG and Novartis entered into a global exclusive development and commercialization license agreement, or the Novartis Agreement. Pursuant to the Novartis Agreement, we granted to Novartis an exclusive, royalty-bearing, sublicensable and transferable license to develop, manufacture, and commercialize VAV1 MGDs, including MRT-6160, which is currently in Phase 1 clinical development for immune-mediated conditions. We are responsible for completing the ongoing Phase 1 clinical study and Novartis is responsible for all subsequent development and commercial activities starting at Phase 2. Development and commercial activities governed by the Novartis Agreement will be overseen by a Development Committee and a Commercialization Committee.

Pursuant to the Novartis Agreement, we received from Novartis an upfront payment of $150 million, and are eligible to receive from Novartis (1) up to $2.1 billion in development, regulatory, and sales milestones, beginning upon initiation of Phase 2 studies including (a) potential development and regulatory milestone payments, exceeding $1.5 billion if multiple indications achieve regulatory approval in multiple territories, (b) potential sales milestones payments in connection with sales outside of the United States, and (2) tiered royalties on sales outside of the United States. We will continue to be responsible for costs associated with the ongoing Phase 1 clinical study and Novartis will be responsible for costs associated with any subsequent clinical studies. We and Novartis also agreed to a net profit and loss sharing arrangement, pursuant to which we will co-fund any global clinical development from Phase 3 onwards and will share 30% of any profits and losses associated with the manufacturing and commercialization of the licensed products in the United States. We have defined opportunities to opt out of the net profit and loss sharing arrangement, in such case, sales in the United States would be entitled to the potential sales milestones payments and tiered royalties on sales available outside of the United States. Any costs for any co-funded development and commercialization activities are subject to budgets reviewed by the Development Committee and Commercialization Committee, respectively. The Novartis Agreement includes customary termination provisions, including Novartis’ ability to terminate the Novartis Agreement in its entirety. On December 11, 2024, we announced the closing of the Novartis Agreement.

Research and development expenses

Our research and development expenses include:

expenses incurred under agreements with consultants, third-party service providers that conduct research and development activities on our behalf;

personnel costs, which include salaries, benefits, pension and stock-based compensation;

laboratory and vendor expenses related to the execution of preclinical and clinical studies;

laboratory supplies and materials used for internal research and development activities; and

facilities and equipment costs.

Most of our research and development expenses have been related to the development of our QuEENTM discovery engine and advancement of our GSPT1 and VAV1 programs, and advancement of our disclosed and undisclosed programs including for NEK7, CDK2, and CCNE1.

We expense all research and development costs in the periods in which they are incurred. Costs for certain research and development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors and third-party service providers.

The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects, the costs of related clinical development costs or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

We expect our research and development expenses to increase substantially for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates, including investments in manufacturing, as we advance our programs and conduct clinical trials. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects, the costs of related clinical development costs or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses

Our general and administrative expenses consist primarily of personnel costs and other expenses for outside professional services, including legal fees relating to patent and corporate matters, professional fees for accounting, auditing, tax and administrative consulting services, insurance costs and other operating costs. We expect our general and administrative expenses to increase over the next several years to support our continued research and development activities, manufacturing activities, and the potential commercialization of our product candidates and development of commercial infrastructure. We also anticipate our general and administrative costs will increase with respect to the hiring of additional personnel, fees to outside consultants, lawyers and accountants, and increased costs associated with being a public company, such as expenses related to services associated with maintaining compliance with Nasdaq listing rules and SEC reporting requirements, insurance and investor relations costs.

Non-operating income and expense

Our non-operating income and expense includes (i) interest earned on our investments, including principally marketable securities and cash; (ii) gains and losses on transactions of our Swiss subsidiary denominated in currencies other than the U.S. Dollar; (iii) proceeds from the sale of fixed assets; and (iv) realized losses on the sale of marketable securities.

Results of operations for the years ended December 31, 2024 and 2023

The following sets forth our results of operations:

Year endedDecember 31,

Operating expenses:

Collaboration revenue

Collaboration revenue for the year ended December 31, 2024 was $75.6 million, of which $34.0 million and $41.6 million were attributable to our license and collaboration agreements with Roche and Novartis, respectively. We did not recognize collaboration revenue for the year ended December 31, 2023.

Research and development expenses

We use our personnel and infrastructure resources across the breadth of our research and development activities, which are directed toward identifying and developing product candidates. As such, we do not track all of our internal research and development expenses on a program-by-program basis. The following table summarizes our research and development expense for each period presented (program expenses are not separately included in the table below prior to the year they are disclosed):

Year Ended December 31,

External research and development expense:

As of December 31, 2024, and December 31, 2023, we had 105 employees engaged in research and development activities in our facilities in the U.S. and Switzerland.

Most of our research and development expenses were driven by the successful achievement of key development milestones in our research and development organization, including the continuation of the MRT-2359 clinical study, the advancement of MRT-6160 into the clinic, the progression of our preclinical pipeline including research performed for our collaboration with Roche, and the continued development of the Company’s QuEENTM discovery engine, and reflect increased personnel expense and external R&D costs to achieve these milestones. Research and development expenses included non-cash stock-based compensation of $10.6 million and $8.9 million for the years ended December 31, 2024 and 2023, respectively.

136

General and administrative expenses

General and administrative expenses to support our business activities were comprised of:

Year endedDecember 31,

As of December 31, 2024, and December 31, 2023, respectively, we had 29 and 28 employees engaged in general and administrative activities principally in our U.S. facility. Personnel and professional service costs increased in the year ended December 31, 2024, as compared to 2023 as a result of increased headcount and expenses in support of our growth and operations as a public company. General and administrative expenses included non-cash stock-based compensation of $7.5 million and $7.7 million for the years ended December 31, 2024 and 2023, respectively.

Other expenses, net

Other income (expense), net was comprised of:

Year endedDecember 31,

Foreign currency exchange gain (loss), net 416 (930 )

Gain on disposal of fixed assets — 24

Loss on sale of marketable securities — (131 )

The increase in interest income for the year ended December 31, 2024, is principally attributable to higher interest rates on marketable securities.

Foreign exchange gain on transactions of our Switzerland based subsidiary denominated in currency other than the U.S. dollar increased in the year ended December 31, 2024, as to compared to the loss for year ended December 31, 2023, principally due to the strengthening of the U.S Dollar with respect to, principally, the Swiss Franc.

Provision for income taxes

For the year ended December 31, 2024, we recorded a provision for income taxes of $2.6 million, primarily driven by the current federal and state taxes related to the $50.0 million upfront payment for Roche Agreement, which will be recognized as taxable Global Intangible Low Tax Income, or GILTI.

Liquidity and capital resources

Overview

Due to our significant research and development expenditures, we have generated operating losses since our inception. We have funded our operations primarily through the issuance and sale of convertible promissory notes, convertible preferred stock, public offerings of our common stock or warrants to purchase common stock, registered direct offerings, and through our collaboration agreements.

In May 2024, we entered into an underwriting agreement with TD Securities (USA) LLC, as representative of the several underwriters, related to an underwritten public offering, or the Offering, of 10,638,476 shares of common stock at a price of $4.70 per share, and, in lieu of Common Stock to certain investors, pre-funded warrants to purchase 10,638,524 shares of Common Stock at a price of $4.6999 per pre-funded warrant, which represents the price per share at which shares of Common Stock were sold in this Offering, minus $0.0001, which is the exercise price of each pre-funded warrant. The pre-funded warrants are immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. Aggregate gross proceeds from the Offering were $100 million, or aggregate net proceeds of $96.4 million after deducting the underwriter discounts, commissions, and other offering costs.

137

In December 2024, we also announced the closing of the global exclusive development and commercialization License Agreement with Novartis to advance VAV1-directed MGDs, including MRT-6160. Under the terms of the agreement, we received from Novartis an upfront payment of $150 million.

As of December 31, 2024, we had cash, cash equivalents, restricted cash, and marketable securities, of $377.0 million and an accumulated deficit of $438.6 million. We believe that our cash, cash equivalents, restricted cash, and marketable securities will be sufficient to fund our planned operations for at least one year past the issuance date of these financial statements.

Cash flows

The following table summarizes our cash flows for the periods indicated:

Year endedDecember 31,

Net cash provided by (used in):

Net increase in cash, cash equivalents and restricted cash $ 96,436 $ 72,491

Operating activities

During the year ended December 31, 2024, net cash provided by operating activities of $42.0 million was attributable to our net loss of $72.7 million off-set by an increase in deferred revenue of $83.4 million, $23.3 million in non-cash charges, and changes in our working capital accounts of $8.0 million. Non-cash charges primarily include stock-based compensation expense of $18.1 million and depreciation expense of $8.1 million.

During the year ended December 31, 2023, net cash used in operating activities of $43.8 million was attributable to our net loss of $135.4 million off-set by an increase in deferred revenue of $50.0 million, $19.1 million in non-cash charges, and changes in our working capital accounts of $22.5 million. Non-cash charges primarily include stock-based compensation expense of $16.7 million and depreciation expense of $6.2 million.

Investing activities

Cash used in investing activities of $44.5 million during the year ended December 31, 2024, was primarily attributable to the purchases of marketable securities of $230.4 million and property and equipment of $4.0 million, off-set by cash provided by financing activities attributable to the maturities of marketable securities of $189.9 million.

Cash provided by investing activities of $88.8 million during the year ended December 31, 2023, was primarily attributable to proceeds from maturities of marketable securities of $165.3 million and proceeds from the sale of marketable securities of $45.6 million, off-set by purchases of marketable securities of $103.2 million and property and equipment of $19.0 million.

Financing activities

Net cash provided by financing activities for the year ended December 31, 2024 amounted to $98.9 million principally attributable to net proceeds from our stock offerings of $97.3 million.

Net cash provided by financing activities for the year ended December 31, 2023 amounted to $27.5 million principally attributable to the sale of pre-funded warrants for aggregate net proceeds of $24.9 million.

Funding requirements

Any product candidates we may develop may never achieve commercialization and we anticipate that we will continue to incur losses for the foreseeable future. We expect that our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase. As a result, until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, third-party clinical research, manufacturing and development services, costs relating to the build-out of our headquarters, laboratories and manufacturing facility, license payments or milestone obligations that may arise, laboratory and related supplies, clinical costs, manufacturing costs, legal and other regulatory expenses and general overhead costs.

138

Based upon our current operating plan, we believe that the existing cash, cash equivalents, restricted cash, and marketable securities of $377.0 million, will enable us to fund our operating expenses and capital expenditure requirements for at least the next twelve months. We base this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

We will continue to require additional financing to advance our current product candidates through clinical development, to develop, acquire or in-license other potential product candidates and to fund operations for the foreseeable future. We will continue to seek funds through equity offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at

all. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders, will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies. If we are unable to raise capital, we will need to delay, reduce or terminate planned activities to reduce costs.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

the scope, progress, results and costs of researching, developing and manufacturing our current product candidates or any future product candidates, and conducting preclinical studies and clinical trials;

the timing of, and the costs involved in, obtaining regulatory approvals or clearances for our lead product candidates or any future product candidates;

the number and characteristics of any additional product candidates we develop or acquire;

the cost of manufacturing our lead product candidate or any future product candidates and any products we successfully commercialize, including costs associated with building-out our manufacturing capabilities;

our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of any such agreements that we may enter;

the expenses needed to attract and retain skilled personnel;

the costs associated with being a public company;

the timing, receipt and amount of sales of any future approved or cleared products, if any; and

the effect of global economic uncertainty and financial market volatility caused by economic effects of rising inflation and interest rates, global health crises, geopolitical events, changes in international trade relationships and military conflicts on any of the foregoing or other aspects of our business or operations.

Further, our operating plans may change, and we may need additional funds to meet operational needs and capital requirements for clinical trials and other research and development activities. We currently have no credit facility or committed sources of capital. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated product development programs.

Critical accounting policies and significant judgments and estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

139

We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Research and development expense and accruals

We record research and development expenses to operations as incurred. Research and development expenses represent costs incurred by us for development of our technology discovery engine and the discovery and development of our product candidates and include: employee-related expenses, including salaries, benefits and non-cash stock-based compensation expense; external research and development expenses incurred under arrangements with third parties, including preclinical testing organizations, non-profit institutions and consultants; and other expenses, which include direct and allocated expenses for laboratory, facilities and other costs.

As part of the process of preparing financial statements, we are required to estimate and accrue expenses. We estimate costs of research and development activities conducted by service providers. Payments made prior to the receipt of goods or services to be used in research and development are deferred and recognized as expense in the period in which the related goods are received or services are rendered. If the costs have been prepaid, this expense reduces the prepaid expenses in the balance sheet, and if not yet invoiced, the costs are included in accrued expenses in the balance sheet. We classify such prepaid assets as current or non-current assets based on our estimates of the timing of when the goods or services will be realized or consumed. These costs are a significant component of our research and development expenses.

We estimate these costs based on factors such as estimates of the work completed and budget provided and in accordance with our agreements with established third-party service providers. We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued expense balance in each reporting period. As actual costs become known, we adjust our estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed may vary from our estimates and could result in us reporting amounts that are too high or too low in any particular period. Our accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from external third-party service providers. Amounts ultimately incurred in relation to amounts accrued for these services at a reporting date may be substantially higher or lower than our estimates.

We have and may continue to enter into license agreements to access and utilize certain technology. We evaluate if the license agreement is an acquisition of an asset or a business. To date none of our license agreements have been considered to be an acquisition of a business. For asset acquisitions, the upfront payments to acquire such licenses, as well as any future milestone payments made before product approval, are immediately recognized as research and development expense when due, provided there is no alternative future use of the rights in other research and development projects.

Revenue Recognition

To date, our revenues have primarily consisted of consideration related to the Roche License and Collaboration Agreement and the Novartis License Agreement. Goods and service that we are required to provide to Roche and Novartis under these agreements are accounted for under ASC 606. In accordance with ASC 606, we recognize revenue when our customers obtain control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services.

To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, we perform the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the assessment of the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when, or as we satisfy each performance obligation.

As part of the accounting for arrangements under ASC 606, we must use significant judgment to determine the performance obligations based on the determination under step (ii) above. We also use judgment to determine whether milestones or other variable consideration, except for royalties and sales-based milestones, should be included in the transaction price as described below. We recognize revenue based on those amounts when, or as, the performance obligations under the contract are satisfied.

140

The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method, depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in management’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. The consideration to be received is allocated among the separate performance obligations based on relative standalone selling prices. Determining the standalone selling price of each performance obligation requires significant judgment and is discussed in further detail in Note 9.

We utilize judgment to assess the nature of the performance obligation to determine whether the performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition. The measure of progress, and the resulting periods over which revenue should be recognized, are subject to estimates by management and may change over the course of the arrangement, which are subject to review by the joint research committee, or JRC. Such a change could have a material impact on the amount of revenue we record in future periods. We concluded that the transfer of control to the customer for the performance obligation occurs over the time period that the research and development services are provided by us. We recognize revenue for the performance obligation as those services are provided using an input method, based on the cumulative costs incurred compared to the total estimated costs expected to be incurred to satisfy the performance obligation. The percentage of completion method is, in management’s judgment, the best measure of progress towards satisfying the performance condition.

At the inception of each arrangement that includes research, development or regulatory milestone payments, we evaluate whether the milestones are considered likely to be met and estimate the amount to be considered for inclusion in the transaction price using the most-likely-amount method. If it is probable that a significant reversal in the amount of cumulative revenue recognized would not occur, the associated milestone value is included in the transaction price. For milestone payments due upon events that are not within our control, such as regulatory approvals, we are not able to assert that it is likely that the regulatory approval will be granted and that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur until those approvals are received. In making this assessment, we evaluate factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone. There is considerable judgment involved in determining whether it is probable that a significant reversal in the amount of cumulative revenue recognized would not occur.

We reevaluate the transaction price and our total estimated costs expected to be incurred at the end of each reporting period and as uncertain events, such as changes to the expected timing and cost of certain research, development and manufacturing activities that we are responsible for, are resolved or other changes in circumstances occur. If necessary, we will adjust our estimate of the transaction price or our estimates of the total costs expected to be incurred. To date, we have not had any significant changes in our estimates.

For a complete discussion of our significant accounting policies and recent accounting pronouncements, see Note 2 to our consolidated financial statements appearing elsewhere in this Annual Report.

Contractual obligations and commitments

Roche Collaboration and License Agreement

141

On October 16, 2023, we entered into a Collaboration and License Agreement with Roche, for the discovery and development of molecular glue degraders against targets in cancer and neurological diseases. Under the Roche Agreement, we will lead the discovery and certain preclinical activities against multiple select targets. Following the completion of certain preclinical studies, Roche has the option to continue the further development and potential commercialization of compounds identified and generated under the collaboration and products containing such compounds at its sole responsibility and at its own cost. The initial scope of the agreement is limited to a specified number of targets but may be expanded to include additional targets subject to certain conditions and additional compensation payable to us. Pursuant to the terms of the Roche Agreement, we granted to Roche an exclusive license to use certain of its platform technology for the exploitation of compounds and products discovered and developed under the agreement. We received an upfront payment of $50.0 million and milestone payments of $9 million from Roche under the terms of the Roche Agreement. Additionally, we are eligible to receive additional contingent payments from Roche upon the occurrence of defined research, development, regulatory and sales-based events exceeding $3 billion. We are also entitled to tiered royalties on sales of products containing compounds identified and generated from activities conducted under the arrangement. The Roche Agreement term commences on the execution date and continues until no payment obligations remain, unless otherwise terminated earlier.

Novartis License Agreement

On October 25, 2024, we entered into a License Agreement with Novartis. Pursuant to the Novartis Agreement, we will grant to Novartis an exclusive, royalty-bearing, sublicensable and transferable license to develop, manufacture, and commercialize VAV1 MGDs, including MRT-6160, which is currently in Phase 1 clinical development for immune-mediated conditions.

Limitations on effectiveness of controls and procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of disclosure controls and procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated, as of December 31, 2024, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act).

Based on this assessment, our management concluded that, as of December 31, 2024, our internal control over financial reporting was effective.

Nominating and Corporate Governance Committee

Anthony Manning, Ph.D., Andrew Schiff and Jan Skvarka, Ph.D, MBA, serve on the nominating and corporate governance committee, which is chaired by Jan Skvarka, Ph.D, MBA. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2024, the nominating and corporate governance committee met three (3) times. The nominating and corporate governance committee’s responsibilities include:

reviewing the composition of the board of directors to ensure that it is composed of members containing the appropriate skills and expertise to advise us;

Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described in our proxy statement under the heading “Stockholder Proposals.” The nominating and corporate governance committee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described in our proxy statement under the heading “Stockholder Proposals.”

150

Identifying and Evaluating Director Nominees. Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Insider Trading Policies and Procedures

We have adopted an insider trading policy that governs the purchase, sale, and/or other transactions of our securities by our directors, officers, employees and designated consultants that we believe is reasonably designed to promote compliance with applicable insider trading laws, rules and regulations, and listing standards applicable to us. A copy of our insider trading policy is filed as Exhibit 19.1 to this Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Our insider trading policy prohibits our directors, officers, employees and certain designated consultants, and their affiliated persons, from trading in company securities while in possession of material nonpublic information about our company. The policy also prohibits tipping (i.e., disclosing material nonpublic information about our company to others who may trade of the basis of that information). Under our insider trading policy, designated insiders may only trade in company securities at a time when they do not possess material nonpublic information about our company. We also require our directors, officers and certain other employees to receive approval before trading in company securities. Our insider trading policy also expressly prohibits short sales; purchases or sales of puts, calls, or other derivative securities or hedging transactions; using company securities as collateral in a margin account; or pledging company securities as collateral for a loan. Any waiver of the provisions of this policy requires the approval of our Audit Committee. To date, no such requests have been made or approved. We have also adopted an additional policy that governs adoption, modification and termination of written securities trading plans, known as Rule 10b5-1 plans, by our directors, executive officers and certain other persons. Our policy provides that all Rule 10b5-1 plans must comply with SEC rules applicable to the Rule 10b5-1 safe harbor and imposes additional requirements and limitations.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the corporate governance section of our website, which is located at https://ir.monterosatx.com/corporate-governance/documents-and-charters. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8-K.

Narrative to 2024 Summary Compensation Table

Our board of directors and compensation, nomination and corporate governance committee review compensation annually for our executive officers. In setting executive base salaries and bonuses and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our Company. We target a general competitive position, based on independent third-party benchmark analytics to inform the mix of compensation of base salary, bonus or long-term incentives.

Our compensation, nomination and corporate governance committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our executive compensation programs and related policies. In fiscal year 2024, the compensation, nomination and corporate governance committee continued to retain Radford, an AonHewitt Company, or Radford, to provide it with market information, analysis and other advice relating to executive compensation on an ongoing basis. The compensation, nomination and corporate governance committee engaged Radford to, among other things, assist in developing a group of peer companies to help us determine overall compensation for our executive officers, as well as to assess each separate element of compensation. The goal was to ensure that the compensation we offer to our executive officers, individually as well as in the aggregate, is competitive and aligned with our business and executive talent requirements. We do not believe the retention of, and the work performed by, Radford creates any conflict of interest because Radford performs no other work for the Company besides advising the compensation, nomination and corporate governance committee.

Our compensation, nomination and corporate governance committee is responsible for determining the compensation for all executive officers. Based on its discretion, taking into account the factors noted above, the compensation, nomination and corporate governance committee sets the compensation for each executive officer, including for the Chief Executive Officer, without the Chief Executive Officer present.

Base Salaries

152

Base salaries for our named executive officers are reviewed periodically and adjusted from time to time based on factors including market-competitive compensation levels, job responsibilities, individual performance and experience. The 2024 base salaries for Dr. Warmuth, Dr. Janku, and Dr. Nickson were $616,400, $500,000, and $473,611, respectively.

Annual Bonuses

For the fiscal year 2024, each named executive officer was eligible to earn an annual cash bonus pursuant to our Senior Executive Cash Incentive Bonus Plan based on achievement of certain company and individual-performance goals as determined by the Company in its sole discretion. The target annual bonus for each of Dr. Warmuth, Dr. Janku, and Dr. Nickson were 50%, 40%, and 40% of each of the named executive officer’s annual base salary.

Equity Compensation

Our equity grant program is intended to align the interests of our named executive officers with those of our stockholders and to motivate them to make important contributions to our performance. In 2024, we granted stock options to each of our named executive officers, as reflected in the “Outstanding Equity Awards at 2024 Fiscal Year End Table” below.

401(k) Plan

We maintain a tax-qualified retirement plan that provides all regular U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. Under our 401(k) plan, participants may elect to defer a portion of their compensation on a pre-tax basis or after tax (Roth) basis subject to applicable annual limits under the Code. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. Employee elective deferrals are 100% vested at all times. As a U.S. tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan and all contributions are deductible by us when made and earnings on Roth contributions are not taxable when distributed from the 401(k) Plan. We make safe-harbor match contributions of 100% of the first 4% of each participant’s eligible compensation.

Other Benefits

Our named executive officers are eligible to participate in our employee benefit plans on the same basis as our other employees, including our health and welfare plans.

Employment Arrangements with Our Named Executive Officers

We entered into employment agreements with each of Dr. Warmuth, Dr. Janku, and Dr. Nickson, effective upon our initial public offering in 2021. The employment agreements contain substantially similar terms that provide for each of the named executive officer’s continued employment and annual base salary, and set forth the terms of their annual bonus, the at-will nature of their employment, certain expense reimbursements, the terms of severance payments payable upon certain terminations of employment and their eligibility to participate in our benefit plans generally.

In the event that Dr. Warmuth’s, Dr. Janku’s, or Dr. Nickson’s service with the Company is terminated without “cause” or for “good reason” (in each case, as defined in his employment agreement), within three month prior to or twelve months after a “change in control” (as defined in his employment agreement), such named executive officer will be entitled to the following severance benefits, subject to the executive executing a separation agreement and it becoming effective, (i) a lump-sum payment equal to equal to the sum of (a) 12 months (or, in the case of Dr. Warmuth, 18 months) of such named executive officer’s then-current base salary or the base salary in effect immediately prior to the change in control, if higher, plus (b) one times (or, in the case of Dr. Warmuth, 1.5 times) such named executive officer’s annual target bonus for the then-current year; (ii) up to 12 months (or, in the case of Dr. Warmuth, 18 months) of the employer portion of COBRA premium payments; and (iii) in the case of Dr. Warmuth, any vested stock options granted prior to the effective date of his employment agreement shall be exercisable until the earlier of the expiration date of such options or the first anniversary of his date of termination unless the equity documents pursuant to which such stock options are granted require or authorize earlier termination in connection with a liquidation or sale of the Company.

153

In the event that Dr. Warmuth’s service with the Company is terminated without “cause” or for “good reason,” in each case, other than in connection with a change in control, such named executive officer will be entitled to the following severance benefits, subject to such executive executing a separation agreement and release and it becoming effective: (i) payments equal to the sum of (a) 12 months of Dr. Warmuth’s then-current base salary, plus (b) his annual target bonus for the then-current year; and (ii) up to 12 months of the employer portion of COBRA premium payments.

In the event that Dr. Janku’s or Dr. Nickson’s service with the Company is terminated without “cause” or for “good reason,” in each case, other than in connection with a change in control, such named executive officer will be entitled to the following severance benefits, subject to such executive executing a separation agreement and release and it becoming effective: (i) payments equal to 12 months of such named executive officer’s then-current base salary, and (ii) up to 12 months of the employer portion of COBRA premium payments.

Upon the occurrence of a change of control, all payments and benefits received by Dr. Warmuth, Dr. Janku, and Dr. Nickson in connection with a change of control that constitute “excess parachute payments” under Section 280G of the Code will be subject to a modified economic cutback treatment such that the “excess parachute payments” to be received by each such affected named executive officer will either be (i) paid in full or (ii) reduced below such named executive officer’s threshold amount under Code Section 280G in order to avoid triggering the excise tax that would otherwise be payable on such “excess parachute payment” amounts.

In addition, each of our named executive officers previously entered into our standard confidential information, non-competition, non-solicitation, and invention assignment agreement with us which continues to remain in effect and contains protections of confidential information, requires the assignment of inventions and contains other restrictive covenants.

Compensation Risk Assessment

We believe that although a portion of the compensation provided to our named executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. Our compensation programs are designed to encourage our named executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits derivative transactions of our stock by our executive officers, directors and employees. Our insider trading policy expressly prohibits purchases of any derivative securities that provide the economic equivalent of ownership.

Compensation Recovery Policy (Clawback Policy)

On September 27, 2023, we adopted a Compensation Recovery Policy (the “Clawback Policy”) in compliance with the requirements of the Dodd-Frank Act, final SEC rules and applicable Nasdaq listing standards (the “final clawback rules”), which covers our current and former executive officers, including all of our named executive officers. Under the Clawback Policy, in the event that we are required to prepare a restatement of our previously issued financial statements due to our material noncompliance with any financial reporting requirement under securities laws, we are required to recover (subject to certain limited exceptions described in the Clawback Policy and permitted under the final clawback rules) any cash or equity incentive-based compensation received by any current or former executive officer after the effective date of the Clawback Policy and in the three years prior to the date we are required to restate our financial statements that is in excess of the amount that would have been received based on the restated financial statements.

Policy on the Timing of Awards of Options and Other Option-Like Instruments

Our compensation committee has generally granted annual equity awards, including stock option grants to our named executive officers, in the first quarter of each fiscal year, specifically early January. In addition, new hires receive stock option grants at the time of their hiring. Eligible employees, including our named executive officers, may voluntarily enroll in our Employee Stock Purchase Plan and receive an option to purchase shares at a discount using payroll deductions accumulated during the prior six months, with purchase dates occurring at the Administrator’s (as defined under the Employee Stock Purchase Plan) discretion. During 2024, our compensation

155

committee did not take into account any material nonpublic information when determining the timing and terms of equity incentive awards, and we did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. During 2024, we did not grant stock options to our named executive officers during any period beginning four business days before and ending one business day after the filing or furnishing of a Form 10-Q, 10-K or 8-K that discloses material nonpublic information.

Director Compensation

The table below shows all compensation earned by or paid to our non-employee directors during the year ended December 31, 2024, or fiscal year 2024. During fiscal year 2024, Markus Warmuth, M.D., our President and Chief Executive Officer, served as a member of our board of directors, as well as an employee, and received no additional compensation for his services as a member of our board of directors in 2024. Dr. Warmuth’s compensation for service as an employee during fiscal years 2023 and 2024 is set forth in the section of this this Annual Report on Form 10-K captioned “Executive Compensation — 2024 Summary Compensation Table.”

Non-Employee Director Compensation Policy

Our non-employee directors are compensated pursuant to a formal policy, which we most recently amended and restated in June 2024, pursuant to which we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairman of each committee receives a higher retainer for such service. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:

Annual Retainer for Board Membership

Annual service on the board of directors $ 40,000

Additional Annual Retainer for Committee Membership

*Committee established in June 2024

Non-employee directors are given the opportunity to elect to receive all or a portion of their cash retainer and committee fees in the form of an equity award of unrestricted shares having a grant date fair value equal to the amount (or portion of the amount) of such retainer and committee fees. We also reimburse our non-employee directors for reasonable out-of-pocket expenses incurred by our non-employee directors in connection with attending our meetings of the board of directors and committees thereof.

During 2024, pursuant to the terms of the non-employee director compensation policy then in effect, each new non-employee director elected to our board of directors was eligible to receive an option to purchase 44,200 shares of our common stock on the date of such director’s election or appointment to the board of directors, which would vest ratably in thirty-six (36) equal monthly installments following the grant date, subject to the director’s continued service on our board of directors through such vesting date and subject to 100% acceleration upon a change in control. In addition, on the date of our 2024 annual meeting of stockholders of our company, each continuing non-employee director was granted an option to purchase 22,100 shares of our common stock, which vests in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting, subject to the director’s continued service on our board of directors through such vesting date and subject to 100% acceleration upon a change in control.

This program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders.

Employee directors receive no additional compensation for their service as a director.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Certain Relationships and Transactions

Other than the compensation agreements and other arrangements described under the sections entitled “Executive Compensation” and “Director Compensation” in this this Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and the transactions described below, since January 1, 2023, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which:

the amount involved exceeded, or will exceed, $120,000 (or, if less, 1% of the average of our total asset amounts at December 31, 2024); and

in which any director, executive officer, holder of 5% or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.

October 2023 Offering

In October 2023, we sold in a registered direct offering, pursuant to a securities purchase agreement, pre-funded warrants to purchase 10,000,400 shares of the our common stock at a purchase price of $2.4999 per pre-funded warrant. Certain existing holders of five percent or more of a class of our capital stock participated in the transaction, as evidenced by the table below.

May 2024 Offering

In May 2024, we sold in an underwritten public offering, 10,638,476 shares of common stock at a public offering price of $4.70 per share and pre-funded warrants to purchase 10,638,524 shares of the our common stock at a purchase price of $4.6999 per pre-funded warrant. Certain existing holders of five percent or more of a class of our capital stock participated in the transaction, as evidenced by the table below.

Indemnification Agreements

We have entered into agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts incurred by such person in any action or proceeding on account of any services undertaken by such person on behalf of our Company or any other company or enterprise to which such person provides services at our request to the maximum extent allowed under Delaware law.

Agreements with Our Stockholders

In connection with our preferred stock financings prior to our IPO, we entered into investors’ rights, voting and right of first refusal and co-sale agreements as well as management rights letters containing registration rights,

162

information rights, voting rights and rights of first refusal, among other things, with certain holders of our convertible preferred stock and certain holders of our common stock. The management rights letters provide for certain information rights and rights to consult with our management. These stockholder agreements and management rights letters terminated immediately prior to the completion of our IPO, other than the provisions relating to registration rights, which continued in effect following the completion of our IPO and entitle the holders of such rights to demand that we file a registration statement, subject to certain limitations, and to request that their shares be covered by a registration statement that we are otherwise filing.

Related Person Transaction Policy

Our board of directors adopted a written related person transaction policy providing that transactions with our directors, executive officers and holders of five percent or more of our voting securities and their affiliates, each a related person, must be approved by the audit committee. This policy became effective on June 23, 2021 in connection with our initial public offering, or IPO. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person will be defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.

Director Independence

Our common stock was approved for listing on The Nasdaq Global Select Market. Under the Nasdaq listing rules, independent directors must comprise a majority of a listed company’s board of directors within twelve months from the date of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation, nomination and corporate governance committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (2) be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board of directors must consider, for each member of a compensation, nomination and corporate governance committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation, nomination and corporate governance committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that all members of the board of directors, except Markus Warmuth, are independent directors, including for purposes of the rules of Nasdaq and the SEC. In making such independence determination, our board of directors considered the relationships that each director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each director. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers.

Audit Committee Pre-approval Policy and Procedures

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Monte Rosa Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Monte Rosa Therapeutics, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows, for each of the two years in the period ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 23 headings are on that chain and 17 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
