Background of the investigation
On April 27, 2026, Qiagen announced preliminary results for the first quarter of 2026. Among other things, the Company disclosed that net sales declined approximately 1% on a constant exchange rate (“CER”) basis, and that sales of its QuantiFERON product declined approximately 5% CER.
In addition, Qiagen lowered its full-year 2026 outlook, reducing its expected sales growth to approximately 1% to 2% CER. The Company attributed the weaker performance, in part, to a “significant decline in immigration testing demand,” which impacted its QuantiFERON franchise.
Following this disclosure, Qiagen’s stock price declined approximately 10%, damaging investors.
In light of this disclosure, Johnson Fistel is investigating whether Qiagen complied with the federal securities laws. If you suffered losses from your investment in Qiagen stock, contact Johnson Fistel.
