QGEN Investor Alert: Levi & Korsinsky Investigates Qiagen (QGEN) for Potential Securities Fraud

Qiagen's forward-looking non-GAAP guidance lacked required GAAP reconciliations under SEC Regulation S-K Item 10(e) -- institutional investors who relied on these figures for portfolio allocation decisions may have been deprived of material information.

NEW YORK, May 13, 2026 /PRNewswire/ -- Qiagen N.V. (NASDAQ: QGEN) shares dropped approximately 10% after the company slashed its FY 2026 sales-growth outlook from "at least 5% CER" to approximately 1-2% CER and cut adjusted diluted EPS guidance to at least $2.43, down from the $2.50 floor issued just weeks earlier. Institutional shareholders and fiduciaries who allocated capital based on Qiagen's forward-looking non-GAAP metrics are encouraged to submit information regarding their losses here . You may also contact Joseph E. Levi, Esq. via email at [email protected]  or by telephone at (212) 363-7500.

Qiagen presented adjusted diluted EPS guidance -- the primary metric used by analysts and institutional portfolio managers to model the company's valuation -- without providing the corresponding GAAP reconciliation. In its November 6, 2025 Form 6-K filing, the company stated: "We do not reconcile forward-looking non-GAAP financial measures to the corresponding GAAP measures ... reconciliations ... are not available without unreasonable effort." SEC Regulation S-K Item 10(e) requires such reconciliations when non-GAAP measures are presented. Fiduciaries conducting due diligence on QGEN lacked a GAAP baseline against which to evaluate the adjusted figures that anchored the company's investment thesis.

Separately, Qiagen's 2026 Form 20-F disclosed that $498.4 million of debt previously classified as long-term as of December 31, 2024, was reclassified to current. The company characterized this correction as "not material to the previously issued financial statements." Institutional investors relying on prior balance sheet presentations for liquidity analysis, covenant monitoring, or credit assessment operated with a materially different picture of the company's near-term obligations than what the corrected financials reflected.
