We create value by offering integrated workflows that combine consumables with instruments, automation and bioinformatics. This approach allows customers to standardize research and molecular testing and generate actionable insights across applications faster, better and more efficiently.

Our strategy is anchored by a commitment to deliver solid profitable growth by focusing our resources on a group of pillars that represented $1.5 billion in sales, approximately 72% of sales, in 2025 and that are expected to reach combined annual sales of approximately $2 billion by 2028. We are aligning our investments within these pillars to maximize sales in proven high-growth markets.

The pillars involve three product groups where QIAGEN is developing leadership positions: the digital PCR (Polymerase Chain Reaction) platform QIAcuity, the clinical PCR syndromic testing solution QIAstat-Dx and the QIAGEN Digital Insights portfolio of bioinformatics solutions for improved analysis and interpretation of complex genomic data. Additionally, two pillars involve product groups where QIAGEN has strong top positions and where we want to consolidate our leadership: Sample technologies that are used to gain access to DNA and RNA from a biological sample and the QuantiFERON technology platform for latent disease detection, best known for its use in detecting latent tuberculosis (TB).

We classify our products into two main categories: consumables and related revenues; and instruments and related services. Global Presence by Product Category and Geographic Market and QIAGEN Product Groups provide additional details

We manufacture our products at facilities in the United States, Europe and China. In China, products are primarily made for the local market. For more

information about our manufacturing sites, please refer to the Description of Property section.

Our commercial teams are organized into specialized groups across three major regions: Americas; Europe, Middle East and Africa (EMEA); and Asia Pacific and Japan (including China). In certain markets, we also work with third-party distributors to extend our reach. For more information, please refer to the Sales and Marketing section. Details about our employees can be found in the Employees section.

QIAGEN operates a centralized distribution network with regional hubs responsible for local logistics.

Building a sustainable business

Our products support scientific progress and healthcare by enabling molecular insights that can contribute to improved decision-making and patient outcomes worldwide.

Management Report

QIAGEN N.V. | Annual Report 2025 Overview Corporate Governance Financial Statements Appendices Page 20

Understanding and addressing the interests and expectations of our stakeholders is essential for our business strategy and long-term value creation. In 2025, we actively engaged with stakeholders through various channels, incorporating their insights into our materiality assessment, business processes and capital allocation dialogue. These engagements supported decisions on product portfolio priorities, operational improvements, transparency in external reporting and the way we communicate our approach to profitable growth, investment discipline and long-term shareholder value creation.

In particular, engagement with shareholders and the financial community provided feedback not only on sustainability performance and governance, but also on strategy execution, capital deployment priorities and the balance between investing for future growth and maintaining financial discipline. This dialogue helps us explain how we allocate resources to strategic growth pillars, innovation, operational capabilities and other value-enhancing initiatives, while maintaining a focus on returns, resilience and transparency. In accordance with the Dutch Corporate Governance Code, our Stakeholder Engagement Policy is available on our website.

Management Report

QIAGEN N.V. | Annual Report 2025 Overview Corporate Governance Financial Statements Appendices Page 22

Operating Environment

In 2025, global economic growth remained moderate, with the International Monetary Fund (IMF) estimating real GDP growth of about 3%. Inflation eased in many economies, supporting the start of monetary policy easing in some markets, although underlying price pressures persisted in parts of the advanced economies. Growth remained uneven, with advanced economies expanding by around 1.5% and emerging market and developing economies growing at just above 4%.

Economic activity continued to be influenced by elevated public and private debt levels, trade policy uncertainty and geopolitical tensions, contributing to a cautious operating environment across many sectors.

The Life Sciences and molecular diagnostics industries showed mixed conditions in 2025. While demand growth continued in several application areas-including oncology, infectious disease testing and biopharmaceutical research

‌-customer purchasing patterns remained uneven across regions. Companies increasingly emphasized expanding the use of installed instrument platforms and menu breadth to drive growth in clinical and research settings.

QIAGEN remained positioned to address these trends through its global footprint and commercial scale, supported by key platforms such as QIAstat-Dx,

for which cumulative placements exceeded 5,200 instruments worldwide at year-end 2025.

The addressable Life Sciences and molecular diagnostics segments are estimated at about $12 billion in annual sales, with expectations for continued single-digit growth.

Our leadership in molecular research and testing solutions leverages our product portfolio across a wide range of applications. These are grouped into two main categories:

Consumables and related revenues, which include consumables kits, bioinformatics solutions, royalties, co-development milestone payments and services (90% of total net sales in 2025)

Instruments and related services and contracts (10% of total net sales in 2025)

Sample technologies represent one of our pillars and include products involved in the first step of any molecular lab process.

We sell our products to more than 500,000 customers in two broad customer groups: molecular diagnostics (clinical testing) and Life Sciences (academia, pharmaceutical research and development and applied testing).

At the end of 2025, our current total addressable market was estimated at approximately $12 billion annually, with estimates indicating that this market opportunity would grow about 4-6% annually through 2028.

Molecular diagnostics

The molecular diagnostics market includes healthcare providers engaged in many aspects of patient care that require accurate diagnoses and insights to guide treatment decisions in oncology, infectious diseases and immune monitoring.

We offer one of the broadest portfolios of molecular technologies for healthcare. The success of molecular testing in healthcare depends on the ability to accurately analyze purified nucleic acid samples from sources such as blood, tissue, body fluids and stool. Automated systems process tests reliably and efficiently, often handling hundreds of samples simultaneously. Our range of assays for diseases and biomarkers speeds up and simplifies laboratory workflow and standardizes lab procedures.

Molecular testing is the most dynamic segment of the global in vitro diagnostics market. The pandemic has demonstrated the value of molecular testing in healthcare, and we expect the market to provide significant growth opportunities.

We have built a position as a preferred partner to co-develop companion diagnostics paired with targeted drugs and have created a rich pipeline of molecular tests that are transforming the treatment of cancer and other diseases. We have more than 30 master collaboration agreements with pharmaceutical industry customers, some with multiple co-development projects. Companion

‌The markets for most of our products are very competitive. Competitors may have developed, or could develop in the future, new technologies that compete with our products or even render our products obsolete. In sample technology products, we experience competition in various markets from other companies providing sample preparation products in kit form and assay solutions. These competitors include, but are not limited to, companies with a focus on nucleic acid separation and purification kits, assay solutions, reagents and instrumentation. We compete with other suppliers through innovative technologies and products, offering a comprehensive solution for nucleic acid collection, pre-treatment, separation and purification needs as well as downstream applications. Our products provide significant advantages in terms of speed, reliability, accuracy, convenience, reproducibility and ease of use.

Some of our other products within our molecular diagnostics customer class, such as tests for chlamydia, gonorrhea, hepatitis B virus, herpes simplex virus and CMV (cytomegalovirus), compete against existing screening, monitoring and diagnostic technologies, including tissue culture and antigen-based diagnostic methodologies. We believe the primary competitive factors in the market for gene-based probe diagnostics and other screening devices are clinical validation, performance and reliability, ease of use, time to result, standardization, cost, proprietary position, competitors' market shares, access to distribution channels, regulatory approvals and reimbursement.

We believe our competitors typically do not have the same comprehensive approach to sample-to-insight solutions as we do, nor do they have the ability to provide the broad range of technologies and depth of products and services that we offer.

Current and potential competitors may be in the process of seeking Federal Drug Administration (FDA) or foreign regulatory approvals for their respective products. Our continued future success will depend in large part on our ability to maintain our technological advantage over competing products, expand our market presence and preserve customer loyalty. There can be no assurance that we will be able to compete effectively in the future or that development by others will not render our technologies or products noncompetitive.

Net sales for the product categories are based on those revenues related to sample and assay products and related revenues, including bioinformatics solutions, as well as revenues derived from instrumentation sales.

‌Our business is not significantly impacted by seasonal factors. Historically, a portion of our sales has been to researchers, universities, government laboratories and private foundations whose funding is dependent upon grants from government agencies, such as the National Institutes of Health and similar bodies. To the extent that our customers experience increases, decreases or delays in funding arrangements and budget approvals, and to the extent that customers' activities are slowed, such as during times of higher unemployment, vacation periods or delays in approvals of government budgets or government shutdowns, we may experience fluctuations in sales volumes during the year or delays from one period to the next in the recognition of sales. Additionally, we have customers who are active in the diagnostics testing market, and sales to these customers fluctuate to the extent that their activities are impacted by public health concerns. For example, the timing and severity of viral infections such as influenza or the SARS-CoV-2 virus may impact demand for our products.

We are committed to expanding our global leadership in "Sample to Insight" solutions serving customers in the Life Sciences and clinical diagnostics. We target our research and development resources at the most promising technologies to address the unmet needs of our customers in healthcare and research labs in key geographic markets.

We conduct direct-marketing campaigns to announce new products and special promotions, and we offer electronic newsletters and webinars highlighting molecular biology applications.

For laboratories that frequently rely on our consumables, the QIAstock program maintains inventory on-site to keep up with their requirements. QIAGEN representatives make regular visits to replenish the stock and help with other needs, and we are automating this process with digital technologies. Easy-to-use digital ordering, inventory monitoring and customer-driven changes make QIAstock an efficient system for providing ready access to our products for the hundreds of customers worldwide who use this program.

We have made, and expect to continue making, investments in intellectual property. In 2025, additions to our intangible assets outside of business combinations totaled $6.1 million, and as of December 31, 2025, patent and license rights, totaled a net $38.6 million. While we do not depend solely on any individual patent or technology, we are significantly dependent in the aggregate on technology that we own or license. Therefore, we consider protection of proprietary technologies and products one of the major keys to our business success. We rely on a combination of patents, licenses and trademarks to establish and protect proprietary rights. As of December 31, 2025, we owned 280 issued patents in the United States, 214 issued patents in Germany and 1,569 issued patents in other major industrialized countries. We had 353 pending patent applications. Our policy is to file patent

Management Report

QIAGEN N.V. | Annual Report 2025 Overview Corporate Governance Financial Statements Appendices Page 31

applications in Western Europe, the United States and Japan. Patents in most countries have a term of 20 years from the date of filing the patent application. We intend to aggressively prosecute and enforce patents and to otherwise protect our proprietary technologies. We also rely on trade secrets, know-how, continuing technological innovation and licensing opportunities to develop and maintain our competitive position.

Our practice is to require employees, consultants, outside scientific collaborators, sponsored researchers and other advisers to execute confidentiality agreements at the start of their relationships with us. These agreements provide that all confidential information developed by or made known to the individual during the course of the relationship is to be kept confidential and not disclosed to third parties, subject to a right to publish certain information in scientific literature under specific circumstances and other exceptions. In the case of our employees, the agreements provide that all inventions conceived by individuals in the course of their employment will be our exclusive property, subject to local laws.

See Risk Factors included in Risks and Risk Management for details regarding risks related to our reliance on patents and proprietary rights.

‌We strive to ensure that our quality standards, compliance with laws and regulations as well as environmental and social standards are maintained along the entire value chain of suppliers and partners. We demand the same from our business partners. Suppliers are subjected to a risk analysis with regard to environmental and social criteria based on their geographic location. Our supplier policy, which all new suppliers sign, is available on our website and contains requirements with regard to legal compliance, bribery and corruption, labor rights, nondiscrimination and fair treatment, health and safety as well as environmental protection and conservation. In addition, first-tier suppliers must confirm REACH, RoHS and conflict minerals compliance, as appropriate. As part of our supplier assessment procedures, on a monthly basis, we evaluate the supply performance of our raw material and component suppliers. We assess, on a continuous basis, potential alternative sources of

such materials and components and, on a yearly basis, the risks and benefits of reliance on our existing suppliers.

We strive to maintain inventories at a sufficient level to ensure reasonable customer service levels and to guard against normal volatility in availability. We buy materials for our products from many suppliers and are not dependent on any one supplier or group of suppliers for our business as a whole. Raw materials generally include chemicals, raw separation media, biologics, plastics, electronics and packaging. Certain raw materials are produced under our specifications. We have inventory agreements with the majority of our suppliers, and we closely monitor stock levels to maintain adequate supplies.

In 2025, markets experienced increased pressure because of ongoing geopolitical tensions. QIAGEN's strong material positions and thorough coverage ensure that customer product availability remains unaffected at present. However, uncertainty remains about how markets may develop in 2026 in light of ongoing geopolitical tensions.

U.S. legislation mandates transparency in sourcing conflict minerals-tantalum, tin, tungsten and gold-from mines in the Democratic Republic of Congo (DRC) and its adjoining countries. Some of our instrumentation components, purchased from third-party suppliers, contain gold. As required, we investigate our supply chain and disclose any use of conflict minerals from these regions. Annually, we conduct due diligence to determine the presence and origin of conflict minerals in our products. Since we do not purchase directly from smelters or refineries, we rely on supplier declarations. We filed our latest conflict minerals disclosure with the SEC on Form SD for the year ended December 31, 2024, on May 30, 2025, and will update our disclosures as required.

Our primary production and manufacturing facilities for consumable products are in Germany, the United States, Spain and China. Our software development facilities are in the United States, Germany, Poland, Denmark and

Management Report

QIAGEN N.V. | Annual Report 2025 Overview Corporate Governance Financial Statements Appendices Page 32

Romania, and our Center of Excellence for the development of companion diagnostics for personalized healthcare is in the United Kingdom.

Our production and manufacturing operations are highly integrated and supported by sophisticated inventory control and production-planning processes. Production management personnel are highly qualified, and many have advanced degrees in engineering, business and science. In recent years, we have made capital investments principally in automated and interchangeable production equipment to expand production capacity and improve operating efficiency. We have also invested in enterprise systems to support production planning and operational control, including continued deployment and enhancement of SAP-based systems. SAP R/3 is used to integrate the majority of our operating subsidiaries, and we are in the process of a multi-year implementation of S/4HANA.

In addition, capital expenditures include selected investments intended to support energy efficiency and emissions reduction initiatives, including renewable energy projects. Capital expenditures for property, plant and equipment totaled $201.0 million in 2025, $167.2 million in 2024 and

$149.7 million in 2023. These capital expenditures were financed from operating cash flows, and we expect operating cash flows to remain the primary source of funding for future capital expenditures.

We have an established quality system, including standard manufacturing and documentation procedures, intended to ensure that products are produced and tested in accordance with the FDA's Quality System Regulations, which impose current Good Manufacturing Practice (cGMP) requirements. For facilities that accommodate cGMP production, special areas were built, and these facilities operate in accordance with cGMP requirements.

The consumable products manufactured at QIAGEN GmbH in Germany and QIAGEN Sciences LLC in Maryland are produced under ISO 9001: 2015, ISO 13485:2016, MDSAP. By the end of 2025, we aim to complete the implementation of ISO 50001, a voluntary international standard that aids organizations in managing their energy usage. Our certifications form part of our ongoing commitment to provide our customers with high-quality, state-of-the-art sample and assay technologies under our Total Quality Management system.

Our corporate headquarters are located in Venlo, Netherlands. The below table summarizes our largest facilities. Other subsidiaries throughout the world lease smaller amounts of space.

Risks and Risk Management

Role Responsibility

Our Approach

Our risk management approach is built on four key principles:

Active involvement of the Supervisory Board and senior management

Comprehensive policies and procedures

Audit Committee of the Supervisory Board

The Audit Committee of the Supervisory Board oversees the effectiveness of the Company's risk management and internal control systems, regularly reviews and discusses key risks, the overall risk profile, and emerging threats, and evaluates the adequacy of internal controls related to financial reporting, compliance, and operational risks to ensure robust governance and organizational resilience.

Robust risk monitoring, management and information systems

Effective internal controls

Governance and oversight

QIAGEN is managed by a Managing Board and an independent Supervisory

Managing Board The Managing Board provides strategic oversight and governance to ensure that risk management is fully embedded into QIAGEN's long-term objectives and organizational structures, regularly reviewing principal risks, internal controls, and regulatory compliance while overseeing the effectiveness of the risk management system (RMS); it also ensures accurate and transparent external risk disclosures and supports senior management in sustaining a

strong, organization-wide risk culture.

Board, both appointed at the Annual General Meeting of Shareholders. The

Managing Board oversees our risk management system, developing and implementing strategies, controls and mitigation measures to identify and manage current and emerging risks. These risk management policies are embedded in our corporate governance framework, code of ethics and financial reporting controls. Dedicated functional experts continuously evaluate and address business risks.

Executive Committee

Enterprise Risk Management (ERM)

The Executive Committee approves and aligns the ERM and RMS frameworks with QIAGEN's strategic objectives, promotes a strong risk-aware culture, conducts quarterly reviews of key risks and opportunities, ensures effective governance and resources for risk management, and continuously monitors and improves the organization's risk culture.

The Enterprise Risk Management function develops, implements, and continually enhances the ERM framework and processes while coordinating risk management activities across the organization; guides and supports Risk Owners in identifying, assessing, and reporting risks; prepares and delivers risk reports to the Executive Committee and external stakeholders; monitors key risks and opportunities through workshops and assessments; and serves as the primary contact for external audits and regulatory reporting.

Risk Owners Risk Owners identify, assess, and report risks and opportunities within their responsibility, decide and implement appropriate risk response strategies, continuously monitor risk progression and the effectiveness of mitigation measures, escalate risks to the ERM team when they cannot be adequately mitigated, and maintain the risk register by updating entries and providing incident or ad-hoc reports as necessary.

Employees Employees are expected to understand and manage the risks relevant to their roles, follow all established risk management policies and procedures, and actively contribute to a risk-aware culture through their everyday actions and decision-making.

Management Report

QIAGEN N.V. | Annual Report 2025 Overview Corporate Governance Financial Statements Appendices Page 36

QIAGEN Enterprise Risk Management framework

The risk management framework at QIAGEN is built on the internationally recognized standard ISO 31000, integrating risk management into every aspect of the organization's purpose, governance, strategy and operations. The ERM policy establishes a structured approach for identifying, assessing, and responding to key risks and opportunities that could impact the ability of QIAGEN to achieve its objectives. This framework defines clear roles and responsibilities-spanning the Managing Board, Executive Committee, ERM function, Risk Owners, and the Audit Committee of the Supervisory Board-and sets out principles for risk appetite, tolerance thresholds, and risk profile monitoring. The ERM cycle is continuous and iterative, aligning risk management activities with strategic planning, financial cycles and operational decision-making. Key risks are reviewed at least quarterly, with ad-hoc assessments triggered by significant internal or external events, ensuring that risk management remains dynamic and responsive to change. The policy governing the risk management system (RMS) further details how risk is managed through the Three Lines Model, which delineates accountability across operational management, risk oversight and internal audit. The RMS provides a comprehensive process for risk identification, analysis, evaluation, response and monitoring, supported by tools such as the Risk Universe and Risk Register. Risks are assessed using top-down and bottom-up approaches, with prioritization based on likelihood, impact and alignment with QIAGEN's risk appetite. The framework emphasizes a robust risk culture, transparency, and collaboration, ensuring that risk management is a shared responsibility and embedded in daily business activities. Regular reviews and continuous improvement of the ERM and RMS frameworks ensure that QIAGEN remains resilient, compliant, and well-positioned to capitalize on opportunities while mitigating threats.

Assessment of effectiveness of internal risk management and control systems

The Managing Board assesses the effectiveness of QIAGEN's internal risk management and control systems in relation to operational, compliance and reporting risks on an ongoing basis and at least annually. This assessment is informed by the continuous ERM cycle (including quarterly reviews of key risks

and ad-hoc assessments triggered by significant events), the monitoring performed by Risk Owners and relevant oversight functions and the assurance activities embedded in the Three Lines Model. The outcomes of this monitoring and assurance are reviewed within management governance forums and discussed with the Audit Committee of the Supervisory Board as part of the governance cycle, including the status of remediation actions for identified deficiencies and observations.

Risk classification and assessment

We categorize risks into five main types:

Strategic risk - refers to the potential for losses due to a failed business strategy, planning or decision-making. It is associated with the overall future business plans and strategy of a company, including mergers and acquisitions, management of external network/partnerships or changes in management.

Operational risk - is defined as the risk of loss resulting from inadequate or defective systems and internal processes, from human or technical failure and from damage to physical assets.

Compliance risk - refers to the potential for legal penalties, financial forfeiture, and damage to reputation that a company could face as a result of failing to comply with laws, regulations, industry standards or codes of conduct applicable to its business activities.

Financial risk - refers to the possibility of a company experiencing financial losses due to changes on the financial market or wrong/insufficient financial structure management.

External risk - refers to the potential threats or uncertainties that originate outside of a company's control and can negatively impact its operations, performance, or profitability. These risks arise from the organization's interactions with the natural environment, society and regulatory frameworks, and they can affect the long-term sustainability of the business.

Management Report

All risks are assessed based on their likelihood and potential impact on our ability to achieve business objectives. The goal is to identify risks that could materially threaten our success and to implement timely mitigation actions.

Internal controls and compliance

Our corporate governance framework defines the roles of the Managing Board, Supervisory Board and Audit Committee, as detailed under Corporate Governance. We maintain internal controls to ensure the integrity of financial reporting, further described in Controls and Procedures.

Additionally, our Compliance Committee, composed of senior executives from multiple functions, oversees compliance with legal and regulatory requirements and ensures adherence to corporate policies, including our Code of Conduct and Ethics as described in the Corporate Governance section of this annual report.

Risk appetite

Risk appetite is the amount and category of risk that QIAGEN is willing to pursue or retain in the pursuit of its objectives. The risk appetite is documented in a formal statement owned by the Executive Committee, while the Managing Board provides oversight and approval to ensure alignment with the company's strategic direction. This statement serves as a guiding principle for senior management in daily decision-making.

It defines clear parameters for acceptable and unacceptable risks, ensuring consistent and aligned decisions across the organization, and is reviewed and updated annually to remain aligned with strategic priorities.

QIAGEN maintains a balanced risk appetite, seeking to pursue strategic growth opportunities while maintaining robust controls to ensure that risks are managed within defined tolerances and do not compromise our long-term objectives, regulatory compliance or stakeholder trust.

Our business faces significant risks that also threaten the entire industry. Our business, financial condition or results of operations could be materially and adversely affected if any of these risks occurs. In addition, risks and

uncertainties that are currently unknown to QIAGEN or are considered immaterial might affect its business, operations and financial condition. This report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors including the risks described below and elsewhere in this annual report. The risks described below are grouped into main categories, with the risks within each category listed the significant risks. The risks mentioned reflect our risk assessment but do not imply that the company has no other risks and cannot have a material adverse impact on our results of operations, liquidity, or capital resources.

Summary of risk factors

QIAGEN operates in a complex and evolving global environment that presents a broad range of strategic, operational, financial, compliance and external risks which could, individually or collectively, affect the achievement of its strategic objectives, financial condition or long-term sustainability. We maintain a structured enterprise risk management framework designed to identify, assess, and manage these risks; however, no assurance can be given that all risks can be fully anticipated or mitigated.

Strategic risks arise from the need to continuously align our strategy with rapidly changing market conditions, technological developments and stakeholder expectations. This includes the effective integration of environmental, social and governance considerations into decision-making, the successful development and commercialization of innovative products and the ability to respond to competitive pressures and disruptive technologies. Our broad presence in global markets and the execution and integration of acquisitions may expose us to additional economic, political and regulatory uncertainties, potentially affecting anticipated benefits and growth trajectories.

Operational risks relate to the complexity of the company's global operations and reliance on people, systems, suppliers, and partners. The loss of key personnel, disruptions to manufacturing or supply chains, or insufficient resilience could adversely impact operational performance. Increased reliance on digital platforms, data, and advanced technologies, including artificial

intelligence, may introduce ethical, security and governance challenges. Cyber security incidents, system outages or failures to adequately protect sensitive information could result in operational disruption, regulatory scrutiny or reputational harm.

Compliance risks stem from operating in a highly regulated environment across multiple jurisdictions. We are subject to evolving legal and regulatory requirements related to product approvals, quality standards, data protection, anti-bribery and anti-corruption laws, intellectual property, environmental regulations and supply-chain due-diligence obligations. Failure to comply with these requirements, or delays in adapting to regulatory changes, could result in fines, litigation, restrictions on market access, or damage to our reputation.

Financial risks include exposure to changes in tax laws and interpretations, global minimum tax regimes, foreign exchange fluctuations and the potential impairment of goodwill and intangible assets. Our capital structure and debt obligations may limit financial flexibility, while future capital requirements may depend on market conditions and access to funding on acceptable terms.

Variability in customer purchasing patterns and reimbursement environments may also affect forecasting accuracy and financial performance.

External risks arise from factors largely beyond the company's control, including global economic uncertainty, inflationary pressures, interest rate movements, geopolitical conflicts, trade restrictions and changes in public funding or reimbursement policies. These factors may influence customer demand, supply-chain stability, cost structures and market access. In addition, evolving stakeholder expectations related to sustainability and corporate responsibility may affect competitiveness, reputation and long-term value creation.

While we actively monitor and manage these risks within our defined risk appetite, the realization of any of these uncertainties could materially and adversely affect our business, financial condition, results of operations or strategic objectives.

Strategic risks

Our presence in potential high-growth markets exposes us to economic, political and regulatory risks.

In markets emerging across the Middle East and Asia, we may face heightened risks compared to regions where we have an established presence. These risks include:

Economic volatility, particularly in markets reliant on a limited range of industries;

Weak legal systems, which may hinder contract enforcement and intellectual property protection;

Government instability, policy changes and privatization efforts that could impact operations;

Foreign exchange controls that may restrict the movement of funds; and

Abrupt changes in customs and tax regulations, affecting product movement and financial performance.

Additionally, conducting business across multiple jurisdictions-such as moving products between countries or providing services from subsidiaries abroad-increases exposure to regulatory shifts and compliance challenges. These factors could negatively impact our operations and financial results.

Emerging competitors and rapid technological advances in diagnostics, combined with regulatory hurdles, threaten the market position, profitability and growth prospects of our diagnostic and syndromic testing products.

The competitive landscape for our diagnostic portfolio, including QuantiFERON, QIAcuity and QIAstat-Dx, is evolving rapidly. Competitors may introduce new technologies, expand strategic partnerships or obtain regulatory approvals earlier than anticipated, which could adversely impact adoption of our products, limit market share expansion or render certain offerings less competitive. For example, announcements by major industry participants regarding advancements in latent tuberculosis testing, as well as new point of care syndromic testing platforms introduced in key markets, illustrate the pace

at which competitive dynamics can shift. These developments highlight that the absence of clear current regulatory or clinical progress from competitors does not eliminate the risk of future market disruptions.

Additionally, new instruments and assay systems brought to market by competitors may target both established and emerging market segments, potentially outpacing the capabilities of our current technologies. Competitor expansion into the U.S., Europe, Japan and other regions-coupled with evolving trade policies, including U.S. tariffs-may create pricing pressures, influence customer purchasing behavior or challenge our ability to match product breadth and performance.

Regulatory requirements further contribute to this risk. The need to secure timely approvals for new assays or platform enhancements may delay our product launches, limit our ability to respond to market shifts, or hinder execution of our growth strategies. If we do not meet development timelines or effectively navigate regulatory pathways, we may be unable to achieve anticipated revenue targets or capitalize on market opportunities.

If we fail to keep pace with technological innovation, respond to competitive pressures or obtain required regulatory clearances in a timely manner, our market position could weaken, our profitability could be adversely impacted and our ability to achieve planned growth-particularly in high growth diagnostic segments-could be materially and negatively affected.

Challenges in managing growth and acquisition integration may limit expected benefits and adversely impact our performance.

We have grown significantly in recent years, with total net sales increasing from $1.87 billion in 2020 to $2.09 billion in 2025. This growth has been driven by both organic expansion and strategic acquisitions, including the 2025 acquisitions of Parse Biosciences, Inc. and Genoox. We might continue acquiring businesses that align with our Sample to Insight strategy in molecular research and clinical testing. However, successful integration of acquisitions requires significant resources, coordination and expense.

Our ability to manage ongoing growth and execute on expansion initiatives is subject to risks, and the outcomes may not achieve the anticipated benefits or

align with evolving operational, financial or strategic expectations. As we continue to broaden our activities and pursue opportunities to strengthen our portfolio-including through the acquisition of complementary businesses-we may be required to adapt our internal processes, systems and organizational structures to support a larger and more complex operating model. These efforts may place increasing demands on management attention and require significant capital and human resources.

The successful integration of acquired businesses, technologies and personnel remains inherently uncertain. Expansion activities may expose us to challenges related to aligning operations, maintaining consistent standards, integrating systems and processes, and retaining key talent. Acquisitions can also introduce additional regulatory, commercial and financial considerations, including potential liabilities, shifting market dynamics or delays in realizing intended synergies. Performance may also depend on external parties, such as suppliers, partners or acquired teams, whose activities we do not fully control.

As we grow, we may need to expand or enhance our operational and financial control frameworks to ensure continued reliability, consistency and compliance across a broader footprint. In some cases, implementation of new systems or scaling of existing capabilities may temporarily disrupt operations or increase costs. Divergent stakeholder expectations regarding the pace and direction of expansion may also lead to reputational risks if outcomes are perceived as insufficient or misaligned.

Failure to effectively manage growth or integrate acquisitions could result in operational inefficiencies, delays in execution, increased expenses, or challenges in maintaining expected performance levels. In certain circumstances, these developments may also affect our financial condition, reputation or ability to achieve long-term strategic objectives.

We rely on collaborative commercial relationships to develop and/or market some of our products.

We rely on a variety of external partners to develop, commercialize, and distribute certain products. These collaborations-whether with academic institutions, pharmaceutical and biotechnology companies, or regional
