Venlo, the Netherlands, February 4, 2026 - QIAGEN N.V. (NYSE: QGEN; Frankfurt Prime Standard: QIA) today announced results for the fourth quarter and full-year 2025.

Net sales for Q4 2025 rose 4% to $540 million, with sales at constant exchange rates (CER) up 1% and exceeding the outlook for steady CER results compared to the year-ago period while overcoming macroeconomic challenges and the impact of the 2025 U.S. government shutdown. Solid ongoing trends among the growth pillars, which rose 7% CER, led the performance. Net sales results included headwinds of approximately $10 million from discontinued products (NeuMoDx and Dialunox) and the first-time contributions from the Parse acquisition that was completed in December 2025. Adjusted diluted EPS CER of $0.62 CER was above the outlook for about $0.60 CER.

For full-year 2025, QIAGEN achieved its increased sales outlook for 5% CER growth, which was at the high end of the outlook for about +4-5% CER growth. Net sales included headwinds of about $20 million from discontinued products (NeuMoDx and Dialunox) as well as contributions from the Parse acquisition. Adjusted diluted EPS was $2.38, with adjusted diluted EPS of $2.40 CER ahead of the outlook for about $2.38 CER and $0.12 ahead of the initial outlook for 2025. Diluted EPS was $1.94.

For 2026, QIAGEN expects net sales growth of at least 5% CER from 2025 driven by the growth pillars contributing about 9% CER growth and combined sales of about $1.64 billion CER. Adjusted diluted EPS is expected to be at least $2.50 CER compared with $2.38 in 2025.

“QIAGEN finished 2025 with disciplined execution, exceeding our outlook for sales and adjusted EPS in Q4 2025,” said Thierry Bernard, CEO of QIAGEN. “Our performance underscores the strength of our portfolio and positions us well to demonstrate our commitment to delivering solid profitable growth in a challenging environment. Our growth pillars delivered 8% growth to reach $1.49 billion CER in combined sales in 2025 and keeping us on track toward our 2028 targets. We continue to drive efficiency and digitization across the organization to fund growth investments and expand profitability.”

”We also made good progress in capital allocation,” said Roland Sackers, CFO of QIAGEN. “We returned more than $1.1 billion to shareholders to date ahead of schedule and closed two bolt-on acquisitions with Genoox strengthening our QDI business and Parse expanding our Sample technologies portfolio with our entry into single-cell analysis. At the same time, we maintain significant flexibility to continue investing in growth and shareholder returns."

Please refer to accompanying tables in this release for full income statement information and a reconciliation of reported to adjusted figures.

Tables may have rounding differences. Percentage changes are to prior-year periods.

•Sales: Despite macroeconomic challenges and the impact of the U.S. government shutdown, Q4 2025 net sales rose 1% CER. Sample technologies led the performance among product groups with 5% CER growth followed by Genomics / NGS at 2% CER. Diagnostic solutions grew 1% CER. For FY 2025, total net sales increased 5% CER driven by the growth pillars.

•Operating income: Operating income for Q4 2025 declined 17% to $99 million compared with the prior-year period. Adjusted operating income, which excludes various charges and other items in both periods, declined 3% to $154 million, with the adjusted operating income margin at 28.6%, compared with 30.6% in Q4 2024. This reflected a decline in the adjusted gross margin to 65.8% from 67.1% in the prior-year period, primarily due to U.S. tariffs. It also reflected higher sales and marketing expenses, which increased to 22.3% from 21.8% in Q4 2024, as well as higher general and administrative expenses, which rose to 6.1% from 5.3% in the year-ago period. The increase in general and administrative expenses included the impact of currency movements and IT infrastructure investments. For FY 2025, the adjusted operating income margin rose to 29.5% of sales from 28.7% in 2024, as operational efficiencies more than offset currency and tariff headwinds. Excluding the impact of tariffs, which reduced the margin by 80 basis points and the dilutive impact of currency movements by 40 basis points, the adjusted operating income margin increased 200 basis points, which was above the initial 2025 outlook for at least 150 basis points improvement over 2024.

•Earnings per share (EPS): Diluted EPS for Q4 2025 was $0.49, compared with $0.39 in Q4 2024. Adjusted diluted EPS was $0.62 at both actual and CER. For FY 2025, adjusted diluted EPS increased to $2.40 CER from $2.18 in 2024, which represented an increase of $0.12 from the initial 2025 outlook for at least $2.28 CER.

Tables may have rounding differences. Percentage changes are to prior-year periods.

•Sample technologies: Sales in Q4 2025 rose 5% CER to $175 million, driven by growth in automated consumables at a double-digit CER rate compared to the prior-year period and first-time contributions from the Parse acquisition. Instrument sales were also higher compared to Q4 2024, with continued placements of QIAsymphony, QIAcube Connect and EZ2 Connect systems amid a challenging capital spending environment.

•Diagnostic solutions: Sales rose 1% CER in Q4 2025 to $201 million. QIAstat-Dx led the performance with 15% CER growth, driven by double-digit consumables growth. QuantiFERON latent TB sales grew 5% CER, supported by ongoing conversion from the skin test as results were partially offset by major tenders in the prior-year period, which are expected to end as a headwind in Q1 2026.

•PCR / Nucleic acid amplification: Sales in Q4 2025 were $78 million, representing a 9% decline at CER compared with the prior-year period. QIAcuity again delivered double-digit CER consumables growth and reached over 3,200 cumulative placements since launch, as over 100 instruments were added per quarter in 2025 despite ongoing challenging instrument purchasing trends. Other PCR consumables sales, which includes the OEM business, declined at a double-digit rate compared with Q4 2024 due in part to the timing of customer contracts and funding constraints.

•Genomics / Next-generation sequencing (NGS): Sales rose 2% CER to $69 million compared to Q4 2024. QIAGEN Digital Insights (QDI) sales grew at a double-digit CER rate, reflecting solid underlying demand in both clinical and discovery applications. Consumables sales of universal NGS panels declined reflecting funding constraints.

•Net cash from operating activities was $654 million in 2025 compared with $674 million in 2024, including approximately $54 million in cash restructuring payments for the efficiency program initiated in 2024. Free cash flow was $453 million in 2025 compared to $506 million in 2024, reflecting higher investments in property, plant and equipment for projects such as the ERP system upgrade.

•As of December 31, 2025, cash, cash equivalents and short-term investments totaled $1.1 billion compared with $1.2 billion at year-end 2024. Cash flow during 2025 included the return of approximately $300 million to shareholders in January through a synthetic share repurchase and the first annual cash dividend of about $54 million paid in July 2025. Q4 2025 results include a cash outflow of approximately $474 million for the early redemption of the 2027 convertible notes and approximately $225 million for the cash payment related to the Parse acquisition. In January 2026, QIAGEN completed a $500 million synthetic share repurchase, leading to a pro forma leverage of about 1.3 times net debt to adjusted EBITDA.

Portfolio update

QIAGEN is executing on targeted initiatives across its Sample to Insight portfolio to help customers around the world advance science and improve healthcare.

•Sample technologies: QIAGEN completed the acquisition of Parse Biosciences in December 2025, expanding its portfolio into single-cell analysis and advancing the highly scalable Evercode chemistry through new product launches. In parallel, QIAGEN continues to advance its automation roadmap, with three systems on track for launch: QIAsymphony Connect with full IVDR commercialization targeted for mid-2026, QIAsprint Connect set for launch in February 2026 and QIAmini in Fall 2026.

•QIAstat-Dx: QIAGEN has submitted its first blood culture identification panels for U.S. clearance and CE-IVDR registration, as cumulative placements surpassed 5,200 at year-end 2025. Key projects in development involve new panels for complicated urinary tract infections, pneumonia and companion diagnostics.

•QIAcuity: QIAGEN plans to accelerate development of new gene expression assays in 2026 to support pharmaceutical and biopharma adoption. An automated Nanoplate handling solution co-developed with Hamilton on the Microlab STAR platform will also be launched to enable walkaway automation for regulated workflows. Planned assay launches also include solutions for use in cell and gene therapy as well as other pharmaceutical industry applications.

•QIAGEN Digital Insights: Key priorities for 2026 include AI-enabled tools for pharmaceutical R&D, multilingual automation for clinical reporting and agentic AI-based target identification. QIAGEN also plans to expand the Franklin platform, acquired in 2025 with Genoox and integrate single-cell datasets from Parse to support predictive modeling and drug discovery.

•QuantiFERON: QIAGEN is investigating the use of AI-based approaches to support clinical decision-making in latent tuberculosis infection. A new generation of chemistry for Diasorin’s LIAISON QuantiFERON-TB Gold Plus II assay is planned for U.S. launch in 2026, enabling labs to test up to 75% more patients per hour and deliver results faster on automated platforms.

Outlook

For 2026, QIAGEN has initiated its outlook reflecting a challenging macroeconomic environment, which is expected to weigh on results in the beginning of the year. For the full year, net sales are expected to grow at least 5% CER, supported by new product launches as well as the end of sales headwinds from discontinued products (as of June 30, 2026). This outlook includes approximately $1.64 billion in CER sales from QIAGEN’s growth pillars, representing ~9% CER growth compared to 2025. The adjusted operating income margin is expected to remain steady compared to 2025 while absorbing about 160 basis points of pressure from the Parse acquisition as well as from tariffs and currency movements. Adjusted diluted EPS is expected to be at least $2.50 at CER compared to $2.38 in 2025.

For Q1 2026, net sales are expected to increase at least 1% CER from $483 million in Q1 2025. Adjusted diluted EPS is expected to be at least $0.54 CER compared to $0.55 in Q1 2025, driven by the announced dilutive impacts of the Parse acquisition and tariffs.

Based on exchange rates as of February 3, 2026, for full-year 2026, currency movements against the U.S. dollar are expected to have a positive impact on net sales of about one percentage point and a neutral impact on adjusted EPS results. For Q1 2026, currency movements against the U.S. dollar are expected to have a positive impact on net sales of about two to three percentage points and a neutral impact on adjusted EPS results.

Investor presentation and conference call

A conference call is scheduled for Thursday, February 5, 2026, at 15:30 Frankfurt Time / 14:30 London Time / 9:30 New York Time. A live audio webcast will be available in the Investor Relations section of the QIAGEN website (www.qiagen.com), with a recording accessible after the event. The accompanying presentation will be published in advance under "Events and Presentations" in the same section.

Use of adjusted results

QIAGEN reports adjusted results and constant exchange rate (CER) measures, along with other non-GAAP financial metrics, to provide deeper insight into business performance. These include adjusted gross margin and profit, adjusted operating income and expenses, adjusted operating income margin, adjusted net income, adjusted income before taxes, adjusted diluted EPS, adjusted EBITDA, adjusted tax rate and free cash flow. Free cash flow is calculated as cash flow from operating activities less capital expenditures for property, plant and equipment. Adjusted results are non-GAAP measures that QIAGEN views as complementary to GAAP-reported results. They exclude items considered outside of ongoing core operations, subject to significant period-to-period fluctuation, or that reduce comparability with competitors and historical performance. QIAGEN also uses these non-GAAP and constant currency measures internally for planning, forecasting, reporting and employee compensation purposes. These metrics enable consistent comparison of current and past performance, which QIAGEN has historically presented on an adjusted basis.
