Which business segments contributed most to the solid Q2 performance and are there any notable changes in product mix?

Answer

Based on the information that was provided in the Business Wire release, the only quantitative detail that was disclosed is the overall financial performance for Q2 2025:

• Net sales rose 7 % year‑over‑year to $534 million, which represents 6 % growth on a constant‑exchange‑rate (CER) basis—a rate that exceeds the company’s outlook of at least 5 % CER growth.
  
• The company reaffirmed the adjusted diluted EPS target that had been raised earlier in the year and also raised its full‑year 2025 net‑sales‑growth outlook.

What the release does ** not ** contain:

• A breakdown of which business segments (e.g., Core, Sample‑to‑Answer, NGS, or any other specific line‑of‑business) contributed most to the Q2 performance.
• Any explicit mention of changes in product mix (e.g., shifts between consumables, instrumentation, reagents, or services) that might have driven the growth.
• Details on the relative contribution of individual product categories or geographic regions.

Conclusion

The news excerpt you have shared does not provide the level of granularity needed to answer the question about which specific business segments drove the “solid” Q2 performance or whether there were notable changes in the product mix. To obtain those specifics, you would need to consult the full earnings press release, the accompanying investor presentation, or a more detailed earnings commentary from QIAGEN that includes segment‑level sales figures and product‑mix commentary.
