Shareholder letter

Dear Shareholders

In the first quarter, the general equity market reached unprecedented all-time highs, fueled by reinforced expectations of central bank interest rate cuts later in 2024, a persistently robust economy, and the potential of artificial intelligence to catalyze a new industrial revolution. The broader healthcare sector saw gains, bolstered by solid earnings updates and sustained momentum among leading companies in the field of managing the obesity epidemic. However, biotechnology, as reflected by the broader NBI Index, underperformed during this period. This underperformance was mitigated somewhat by a handful of select, smaller M&A transactions and a rebound in small-cap companies from the troughs experienced in October 2023.

The S&P 500 saw a notable increase of 10.6% in USD, and the Nasdaq Composite Index advanced by 9.3% in USD. Similarly, the Euro Stoxx 50 experienced a substantial rise of 12.9% in EUR. The MSCI World Health Care Index climbed 7.7% in USD, although the Nasdaq Biotechnology Index lagged with a modest total return of 1.6% in USD. Biotech investments, often viewed as vulnerable to fluctuations in the interest rate environment, enjoyed a promising start through the end of February. However, apprehension concerning the Federal Reserve's approach to interest rate cuts in 2024 triggered a downturn in March.

Small-cap biotechnology companies mirrored this trend yet outperformed the broader, large-cap dominated NBI Index. The prospect of significant valuation increases, coupled with M&A activity serving as a crucial performance driver in the biotech sector – predominantly targeting smaller capitalized companies – contributed to the superior performance of this subsegment. Illustrative of this trend is the XBI, which achieved a total return of 6.3% in USD, surpassing the NBI Index's return of 1.6% in USD.

For BB Biotech AG, the total return in the first quarter of 2024 was a positive 11.3% in CHF and 7.6% in EUR, inclusive of a dividend payment of CHF 2.00 per share. The portfolio's total return was 11.2% in CHF, 6.3% in EUR, and 3.8% in USD, slightly surpassing the NBI Index. Central bank policies impacted not just the equity markets; notably, the Swiss National Bank's unexpected rate cut devalued the Swiss Franc against other major currencies like the USD and the Euro. This devaluation provided a significant boost to the portfolio in Q1 2024 due to the USD's strengthening against the Swiss Franc, reversing the trend of strong USD devaluation witnessed in the last quarter of 2023. Overall, the net gain for the first quarter of 2024 amounted to CHF 260 mn, a stark contrast to a net loss of CHF 254 mn during the same period in 2023.

AGM 2024

At the Annual General Meeting, BB Biotech AG's shareholders unanimously approved all proposals put forth by the Board of Directors. The shareholders endorsed the proposal for a gross dividend payout of CHF 2.00 per share. This dividend was distributed on March 27, 2024.

Dr. Thomas von Planta was elected as the new Chairman of the Board of Directors, taking over from Dr. Erich Hunziker, who opted not to seek re-election. The Board expressed its gratitude to Dr. Hunziker for his significant contributions and dedication to BB Biotech over the last 13 years. Furthermore, Camilla Soenderby joined as a new member of the Board. The shareholders also re-elected existing Board members Dr. Clive Meanwell, Laura Hamill, Dr. Pearl Huang, and Prof. Dr. Mads Krogsgaard Thomsen for another one-year term.

Continued high investment level

As the first quarter concluded, our investment level neared the upper limit of our target range, reaching 114.1%. This sustained high level of investment underscores the management team's optimistic outlook, recognizing many companies as attractively valued. The team is committed to adhering to our proven investment guidelines, maintaining investment levels between 95% and 115%. The CHF 110 mn dividend payment was primarily financed through the cash proceeds from the divestiture of established and significant investments.

Portfolio update Q1 2024

In the first quarter, portfolio adjustments primarily involved capitalizing on gains from larger, established long-term holdings. This strategy facilitated the dividend distribution in late March and allowed for selective participation in capital increases, augmenting smaller holdings and introducing one new position.

Profit-taking activities targeted mid-to-larger entities such as Vertex, Argenx, Ionis, Intra-Cellular, Moderna, and Neurocrine, alongside minor tactical sales, generating a substantial cash influx of USD 166 mn (CHF 145 mn). The quarter's capital expenditures included for dividend payouts and USD 70 mn (CHF 62 mn) for bolstering existing smaller positions and establishing a new stake in Annexon. BB Biotech engaged in capital increases for Celldex and Esperion. Further portfolio enhancements involved additions to Sage and Generation Bio, and profits from Crispr Therapeutics were reallocated to Beam Therapeutics. A strategic new portfolio entry in the first quarter of 2024 was Annexon, a clinical-stage company focused on developing therapeutic candidates aimed at the complement system to tackle severe autoimmune disorders. CHF 110 mn

By the close of Q1 2024, BB Biotech's portfolio held 30 positions, maintaining a focus on midcap and larger cap biotechnology firms poised for profitability or with sufficient financial backing to achieve profitability, given their current balance sheet strengths. Approximately 30% of the portfolio was invested in early-stage pipeline companies anticipated to require additional funding in the forthcoming years

Portfolio milestones for the first quarter 2024

The biotechnology markets remained volatile, leading to valuation declines in our significant investments in Alnylam and Ionis, triggered by the postponement of critical clinical trial results from the first to the second quarter. This delay impacted our Net Asset Value (NAV) negatively by approximately 1% per position. Alnylam's decision to defer the HELIOS-B trial outcomes for Vutrisiran in TTR cardiomyopathy patients, along with modifications to the trial's primary endpoint, was double-edged. It introduced risks to the trial's success and potentially diminished the market opportunity. Similarly, Intra-Cellular Therapies shares were marked down after the company postponed the publication of data from its Phase III trial of Caplyta in major depressive disorder to April. The company finally announced positive Phase III topline results on April 16, which led to a recovery of the short-term share price losses.

Conversely, our smaller holdings have rebounded from their lows, driven by anticipation of significant milestones. These companies, trading at deep discounts, present substantial upside potential. A notable example is Macrogenics, which contributed approximately 2% to our NAV's return. It is poised to release pivotal Phase II data for vobra duo, its B7-H3 ADC molecule under trial in men with prostate cancer. An initial update is anticipated in May, with further efficacy data expected in the second half of 2024.

Our smaller holdings have rebounded from their lows, driven by anticipation of significant milestones. These companies, trading at deep discounts, present substantial upside potential.

In the first quarter of 2024, the biotechnology sector witnessed significant activity with multiple Phase III trials and numerous proof of concept studies yielding results, including:

• Vertex reported encouraging outcomes from the VX-548 Phase III program for treating moderate-to-severe acute pain. Although VX-548, a selective NaV1.8 inhibitor, was superior to placebo, it did not demonstrate superiority over hydrocodone bitartrate/ acetaminophen. The investor community is now keenly awaiting results from studies evaluating VX-548 in chronic pain, given its much larger market potential, anticipated in 2026.
• Ionis delivered positive top-line results for donidalorsen in treating hereditary angioedema (HAE) patients, showcasing a significant reduction in the rate of HAE attacks. The company has announced plans to release additional results in 2024, including open-label extension data and findings from a cohort of patients transitioning to donidalorsen from other prophylactic HAE medications.
• Agios unveiled improvements in hemoglobin response rates in non-transfusion dependent alpha- and beta-thalassemia patients treated with AG-348, an orally available pyruvate kinase activator. Pivotal Phase III results for AG-348 in treating more severe transfusiondependent alpha- and beta-thalassemia patients are anticipated in the second half of 2024.
• Celldex announced successful Phase II outcomes for barzolvolimab in chronic spontaneous urticaria patients, demonstrating fast onset of drug response and effectiveness in treatment-experienced/refractory patients. Following these results, Celldex plans to initiate a registrational trial in 2024, and capitalized on these positive outcomes by raising USD 460 mn in a capital increase, with BB Biotech participating.
• Argenx reported that Efgartigimod cleared Phase II evaluations for Sjogren's disease (SjD), with plans for a registrational program to follow. This news was particularly well-received, coming after a setback in the fourth quarter of 2023.

The quarter also saw two product approvals and a notable product label update:

• Crispr Therapeutics and Vertex secured US FDA approval for Casgevy to treat transfusiondependent beta thalassemia, following its late 2023 approval for sickle cell disease treatment. The therapy, a one-time treatment that is potentially curative but requires bone marrow transplantation, is expected to see a gradual launch throughout 2024.
• Argenx achieved approval for the intravenous formulation of Vyvgart to treat adults with primary immune thrombocytopenia, while the failure of the subcutaneous formulation in the same condition is under further analysis by Argenx to determine future steps in the US and EU.
• Furthermore, the FDA updated Esperion's Nexletol product label to incorporate cardiovascular outcomes trial results, significantly expanding its total addressable market (TAM) by approving it for not only statin-intolerant patients with high LDL but also for primary prevention. This expansion prompted BB Biotech to participate in Esperion's USD 75 mn capital increase early in the year.

M&A activity started slowly in 2024, with BB Biotech not engaging in the few smaller-sized public M&A transactions announced. Through the acquisition of Morphosys by Novartis, Incyte secured exclusive global development and commercialization rights to tafasitamab (Monjuvi).

Outlook for 2024

Central bank interest rate decisions continue to be a pivotal short-term factor influencing biotech investments. As demonstrated in the first quarter, any adjustment in the timelines and extent of potential rate cuts significantly affects valuations, especially for smaller and mid-cap companies poised to invest heavily in drug development, with revenues and profits anticipated only a few years down the line, assuming everything proceeds as planned. This ongoing uncertainty has already marked the early weeks of the second quarter.

Despite the vagaries of interest rates, the underlying progress and the quality of biotech players, including those within BB Biotech's portfolio, remain solid. Looking forward, we expect a robust news flow from our portfolio companies throughout 2024.

Key anticipated updates include:

• Alnylam's Phase III HELIOS-B results for vutrisiran in TTR cardiomyopathy patients.
• Agios's ENERGIZE-T results for Pyrukynd in transfusion-dependent alpha- and betathalassemia patients.
• Macrogenics's update on the Phase II TAMARACK study for vobra-duo in metastatic castration-resistant prostate cancer patients.
• Revolution Medicines's presentation for RMC-6236, a multi KRAS inhibitor.
• Moderna's anticipated US approval of the RSV vaccine mRNA-1345 in Q2 2024, in time for the fall 2024 vaccine season.

The US healthcare system's focus on cost control, particularly with the implementation of the Inflation Reduction Act (IRA), will become more pronounced in fall 2024 as the negotiated discounts for the first ten drugs set for discounting in 2026/27 are announced. Additionally, with the US presidential election approaching, new healthcare proposals are expected to emerge.

The impending expiration of patents for established pharma pipelines continues to drive M&A activity, with attractive valuations and promising assets and technologies characterizing potential acquisition targets. We anticipate an uptick in takeover activity for the remainder of 2024, following a relatively slow start in the first quarter.

11 Business Report – Shareholder letter

The capital markets have shown improvement for pipeline biotech companies, with an increase in capital raising activities following significant pipeline progress. After the challenges of the post-pandemic years, investors are once again willing to support pipeline companies, enabling them to pursue their development independently. While the secondary market has seen activity, only a few private companies have completed IPOs so far in 2024. With a better start to the year both on the stock exchanges and in terms of fundamental progress, BB Biotech remains optimistic about the attractive future returns offered by our portfolio companies.

We thank you for your continued trust.

Report on the review of condensed consolidated interim financial statements

Introduction

In accordance with the terms of our engagement, we have reviewed the condensed consolidated interim financial statements (consolidated balance sheet, consolidated statement of comprehensive income, consolidated statement of changes in equity, consolidated statement of cash flow and selected explanatory notes) of BB Biotech AG for the period ended 31 March 2024.

These condensed consolidated interim financial statements in accordance with International Accounting Standard 34 «Interim Financial Reporting» and article 14 of the Directive on Financial Reporting of the SIX Swiss Exchange are the responsibility of the Board of Directors whereas our responsibility is to issue a report on these condensed consolidated interim financial statements based on our review.

Scope of Review

We conducted our review in accordance with the Swiss Auditing Standard 910 (SAS 910) «Engagements to Review Financial Statements» and the International Standard on Review Engagements (ISRE) 2410 «Review of interim financial information performed by the independent auditor of the entity». This Standard requires that we plan and perform the review to obtain moderate assurance as to whether the condensed consolidated interim financial statements are free of material misstatements. A review is limited primarily to inquiries of company personnel and analytical procedures applied to financial data and thus provides less assurance than an audit. We have not performed an audit and 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 statements do not give a true and fair view of all material respects of the net assets, the financial position and results of operations in accordance with International Accounting Standard 34 Interim Financial Reporting and article 14 of the Directive on Financial Reporting of the SIX Swiss Exchange.

Company profile

Excellence in Biotech Investments

The access to fast growing biotechnology companies

invests in companies in the fast growing market of biotechnology and is one of the world's largest investors in this sector with 30 years of experience. The shares of BB Biotech are listed on the SIX Swiss Exchange and the Frankfurt Stock Exchange. Its investments are focused on listed companies that are developing and commercializing novel drugs that offer sound value for the healthcare system. BB Biotech

The competent Board of Directors with its long-standing experience set the investment strategy and guidelines. Investment decisions are taken by the experienced investment management team of Bellevue Asset Management AG based on their extensive investment research.

Biotechnology is one of the most attractive of any sector today with estimated annual growth in the double-digits. Mega trends such as increasing life expectancy and a Westernized diet and lifestyle are powerful growth drivers. These mega trends have led to a tremendous increase in healthcare costs, which, in turn, only amplifies the need for more efficient and effective drugs.

Investment strategy

invests in fast-growing biotechnology companies that are developing and marketing innovative drugs. It focuses on biotech companies whose products address areas of significant unmet medical needs and thus have above-average sales and profit-growth potential. BB Biotech

Besides profitable large cap companies, is building up its investments in promising small and mid cap companies. BB Biotech

Diversified portfolio with focus on small and mid cap biotech companies

The team of investment experts is concentrating not only on established target areas such as oncology, orphan diseases and neurological indications, but also on the technologies of tomorrow that could lead to novel treatment methods with attractive therapeutic profiles and substantial economic rewards. These future technologies include RNA platforms and cell and gene therapies. An overall weighted average cost of capital (WACC) of at least 15% is applied to the discounted cash flow models of our portfolio, aligned with our mid-to long term investment objectives.

The asset classes available to BB Biotech are direct investments in the shares of listed companies, equity interests in unlisted companies, corporate bonds, and options on a range of underlying assets. BB Biotech invests almost exclusively in stocks for liquidity and risk/ return reasons. At least 90% of its shareholdings must be in listed companies, while always holding more than 50% of its assets in equity investments. Corporate bonds are an alternative primarily when stock market trends are negative. Options on the stocks of portfolio companies can be bought and sold at opportune times and as a means of hedging currency exposure.

We are focussing on the technologies of tomorrow.

Multi-stage due diligence process based on bottom-up fundamental analysis

Exhaustive, multi-stage due diligence precedes the selection of individual investments. We must have a thorough understanding of every company we invest in. Before an investment is made, the team analyzes a company's financial statements in detail and assesses its competitive environment, R&D pipeline, and patent portfolio as well as its customers' perceptions of its products and services.

Close contact with company executives is of high importance to us in this due diligence process, but also afterwards, as we believe that it takes strong leaders to achieve strong results.

relies on the long-standing experience of its distinguished Board of Directors and on the fundamental analysis of the experienced Investment Management Team of Bellevue Asset Management AG when making its investment decisions. It can also turn to an extensive international network of physicians and specialists in individual sub-segments of the biotech industry for further support and advice. BB Biotech

The Investment Management Team creates detailed financial models for all portfolio holdings and they must provide compelling arguments that these holdings have the potential to double in value over a four-year time frame. The team is guided by its convictions, not by benchmark considerations. Upside potential is driven in most cases by the power of innovation, the launch of new products for serious or significant illnesses, and successful company management. Each investment case is constantly monitored and evaluated within the scope of our stringent and disciplined risk management process and corrective action will be taken if and when necessary.

We follow our own conviction, not a benchmark.

High conviction portfolio consisting of a maximum of 35 positions

investment portfolio will usually consist of between 20 to 35 biotechnology companies. There are estblished large cap companies as well as small and mid cap companies in the portfolio. Smaller positions will be taken in innovative biotech companies with promising R&D pipelines. From a regional perspective, the US biotech sector has displayed a high level of innovation and so this regional bias is also reflected in portfolio. The predominance of the US biotech industry can be traced to the country's stellar research clusters, industry-friendly regulatory frameworks and myriad financing options, among other factors. BB Biotech's BB Biotech's

New investments in small and mid cap companies will have a weighting of between 0.5% and a maximum of 4% to ensure that both upside potential and R&D risks are adequately addressed. Because it is a holding company, has the flexibility to increase portfolio weightings considerably over time as a position increases in value. Smaller positions may become a top holding as their business develops and milestones such as positive Phase III outcomes, drug approvals, the successful marketing of products, and a sustainable flow of profits are achieved. All positions and their valuations are continually monitored, taking into account their growth potential and other aspects, and will be reduced if and when appropriate. BB Biotech

Investment process

Investment process

Source: Bellevue Asset Management

Using a multi-stage process, the universe of around 1000 companies is systematically analyzed and evaluated. The use of artificial intelligence is being explored to deepen our knowledge and understanding. A detailed financial model is created for each investment, which must convincingly demonstrate the potential to double in value over a four-year period. This potential to double in value is based on innovative strength, new products for serious diseases and outstanding management. Each investment is systematically reviewed for sustainability risks and breaches of elementary human rights. Bellevue Asset Management AG is a signatory of UN Principles for Responsible Investment. Besides upholding strict exclusion criteria – such as serious controversies that violate universal norms regarding the environment, human rights or good corporate governance – environmental, social and governance factors are integrated into the fundamental analysis of every company through an ESG integration process in which the associated financial risks or opportunities are evaluated with respect to future stock market performance. The Investment Management Team strive to have an active and constructive dialogue with the management or other relevant stakeholders of the portfolio companies regarding environmental, social and governance aspects – and via proxy voting we use our voting rights actively at the general meetings.

With all of BB Biotech´s investments focusing on biotechnology as a subsector of the healthcare industry, the UN's Sustainable Development Goal number 3: «Good Health and Well-being», is at the core of BB Biotech's investment strategy and our portfolio companies. The investments of BB Biotech AG provide companies with capital in order to allow for drug development to ensure and improve healthy lives and well-being. Therapies to address high unmet medical needs such as for patients suffering from rare disorders, cancer, neurological diseases and chronic cardiovascular and metabolic disorders etc. are key investment selection criteria.

Sustainability at portfolio level

Our investment process fully implements Bellevue Asset Management's formal ESG investment guidelines and therewith all BB Biotech investments are systematically reviewed for sustainability risks and breaches of elementary human rights (as defined, for example, by UN Global Compact principles). Besides upholding strict exclusion criteria – such as serious controversies that violate universal norms regarding the environment, human rights or good corporate governance – environmental, social and governance factors are integrated into the fundamental analysis of every company through an ESG integration process in which the associated financial risks or opportunities are evaluated with respect to future price development. ESG ratings compiled by the global leading ESG research provider MSCI ESG Research are referenced in this process, all the while exercising the necessary prudence and, in some cases, questioning the ESG score.

Before making a positive investment decision, intensive contact is established with the target company's management, since we are convinced that a superior performance can only be achieved with well managed companies.

After being incorporated into portfolio, intense personal contact is maintained with members of the management of the relevant holdings. This closely knit monitoring of the portfolio companies enables to utilize all strategic options on a timely basis, including the early disposal of an equity interest should the fundamental situation significantly deteriorate.
