Navigating the Current Environment: Performance and Strategic Response

The recent past has presented a complex backdrop for the life sciences industry. Following the significant tailwinds and subsequent runoff from the COVID-19 pandemic, 2023 was characterized by challenging comparisons and a more muted market environment. Despite this, Thermo Fisher's operational discipline allowed it to manage costs effectively and continue investing in its strategic priorities.

Entering 2024, market conditions began to show sequential improvement, aligning with the company's expectations. This trend continued into Q1 2025, where Thermo Fisher delivered revenue of $10.36 billion, flat compared to Q1 2024. This reported performance included the impact of two fewer selling days and an approximately 3% headwind from the runoff of COVID-19 vaccine and therapy-related revenue. Excluding these factors, organic revenue growth stood at a respectable 1% in the quarter, demonstrating underlying business strength.

Profitability metrics in Q1 2025 reflected the ongoing operational focus. GAAP operating income grew 3% to $1.716 billion, with the GAAP operating margin expanding by 0.5 percentage points to 16.6%. Adjusted operating income was flat year-over-year at $2.269 billion, resulting in a slight decrease in the adjusted operating margin by 0.1 percentage point to 21.9%. Management attributed this margin dynamic primarily to unfavorable business mix, strategic investments, and foreign exchange impacts, which were largely offset by "very strong productivity improvements" driven by the PPI business system.

Segment performance in Q1 2025 showed varied trends reflecting market dynamics and strategic focus:

• Life Sciences Solutions: Reported revenue grew 2% (2% organic), driven by strength in the bioproduction business. Biosciences revenue was lower due to reduced demand from academic and government customers. Margins were impacted by mix and the Olink acquisition, offset by productivity.
• Analytical Instruments: Reported revenue grew 2% (3% organic), primarily fueled by strong demand in the electron microscopy business. This growth was partially offset by lower demand for chemical analysis products, particularly in China. Margins were affected by strategic investments and FX, offset by productivity.
• Specialty Diagnostics: Reported revenue grew 3% (4% organic), led by the healthcare market channel and the immunodiagnostics and transplant diagnostics businesses. Segment income margin remained flat.
• Laboratory Products and Biopharma Services: Reported revenue declined 1% (1% organic), primarily due to the moderation of COVID-19 related revenue. This headwind was largely offset by strong growth in the pharma services business and the research and safety market channel. Segment income margin was flat, with productivity offsetting unfavorable mix and strategic investments.

Beyond the quarterly numbers, Thermo Fisher continues to execute on its strategic initiatives. The acquisition of Olink, completed in July 2024, is enhancing the company's position in the high-growth proteomics market and is being integrated into the Life Sciences Solutions segment. The recently announced agreement to acquire Solventum's Purification Filtration business for $4.1 billion, expected to close by the end of 2025, will further broaden bioproduction capabilities, adding purification and filtration technologies complementary to existing offerings. These acquisitions, along with the successful integration and performance of past deals like The Binding Site (Protein Diagnostics), underscore Thermo Fisher's disciplined approach to M&A as a key value creation lever.

Furthermore, the company announced a significant $2 billion investment in its United States manufacturing and R&D capabilities over the next four years. This investment is strategically aimed at strengthening American innovation, supporting customer needs for a resilient US healthcare supply chain, and adding capacity in manufacturing and lab services. This move aligns with potential shifts in policy focus and positions Thermo Fisher to capitalize on opportunities for increased domestic activity.

Outlook and the Impact of Shifting Macro Dynamics

Thermo Fisher updated its 2025 guidance to reflect the Q1 performance and, critically, the expected net impact of new macroeconomic factors that have emerged. The updated guidance range for revenue is $43.3 billion to $44.2 billion, implying organic revenue growth of 1% to 3% (2% at the midpoint). The adjusted EPS guidance range is $21.76 to $22.84.

This updated EPS guidance represents a $1 reduction at the midpoint compared to the company's prior outlook. Management explicitly detailed the components of this change: $0.70 is attributed to the expected impact of US-China tariffs, and $0.30 is due to changes driven by the current US policy focus.

The US-China tariffs are anticipated to create a $400 million revenue headwind in 2025, primarily impacting sales of US-produced products into China. This is expected to result in a $375 million headwind to adjusted operating income, net of aggressive mitigation actions already underway. These mitigation efforts, including supply chain adjustments and shifting production, are expected to largely offset the tariff impact, with full benefits realized rapidly in 2026. Non-China related tariffs are also increasing costs but are expected to be offset by mitigation actions and favorable foreign exchange impacts, resulting in no net adjusted EPS impact in 2025.

Changes in US policy focus are expected to lead to more muted purchases from US academic and government customers, particularly for instruments, as funding dynamics are evaluated. This, along with lower expected clinical trials work related to vaccine studies, is projected to reduce the guidance midpoint by $500 million in revenue and $150 million in operating income, translating to the $0.30 adjusted EPS impact.

Despite these headwinds, the updated guidance implies an adjusted operating income margin between 22% and 22.6%. While tariff-related changes reduce the reported margin by 120 basis points (due to FX and tariff costs partially offset by pricing), management emphasized they are focused on protecting profit dollars through productivity and cost management.

The wider guidance range reflects the inherent uncertainty and fluidity of the current macro environment. Management acknowledged that a more significant dampening of the macroeconomic outlook could lead to results at the lower end of the range, while scenarios closer to their original guidance are possible if conditions improve or mitigation actions are more effective than currently assumed.

Beyond 2025, management expressed confidence that the financial impact of these macro-driven changes will reduce rapidly as mitigation actions take full effect and the company capitalizes on new opportunities, such as leveraging its expanded US manufacturing capabilities. The expected free cash flow for 2025 remains robust, projected between $7 billion and $7.4 billion, providing ample capacity for continued strategic investments, M&A, and capital return to shareholders (including $2 billion in assumed share buybacks and approximately $600 million in dividends).

Risks and Considerations

While Thermo Fisher's scale and strategic execution provide significant resilience, investors must consider the key risks highlighted by the company:

• Macroeconomic Uncertainty: The fluid nature of global economic conditions, including potential slowdowns or changes in customer spending patterns, could impact demand across segments.
• Tariffs and Trade Policies: The specific impacts of US-China and other tariffs, while being actively mitigated, introduce near-term headwinds to revenue and profitability. Future changes in trade policy could create additional uncertainty.
• US Policy Focus: Shifts in government funding and priorities, particularly affecting academic and government research and clinical trials, could impact demand in these key end markets.
• Integration Risk: While the company has a strong track record, successfully integrating significant acquisitions like Solventum's Purification Filtration business is crucial to realizing expected synergies and avoiding operational disruption.
• Competition: The competitive landscape remains intense, with specialized players challenging Thermo Fisher in specific niches. Maintaining technological leadership and operational efficiency is essential to defending and expanding market share.
