Perrigo Furnishes Third-Quarter 2026 Results Under Item 2.02

Perrigo Company plc (NYSE:PRGO), incorporated in Ireland, filed a Current Report on Form 8-K on November 4, 2026, disclosing that it released earnings for the third quarter ended September 26, 2026. According to the filing, the press release containing those results is attached as Exhibit 99.1 and is furnished, not filed, meaning it is not subject to the liabilities of Section 18 of the Securities Exchange Act of 1934.

The filing describes the company's use of non-GAAP financial measures alongside its GAAP results. According to the filing, these measures exclude items such as "amortization expense, unusual litigation, impairment charges, restructuring charges, and acquisition and integration-related charges." The company disclosed that the intangible asset amortization excluded from non-GAAP measures "represents the entire amount recorded within the Company's GAAP financial statements" and is excluded because it is not affected by operations of any particular period unless an impairment or useful-life revision occurs. The revenue generated by the associated intangible assets, the company noted, has not been excluded.

The filing also describes a "Core" Perrigo category of measures, which the company states reflects "its go-forward business and excluding Infant Formula and previously announced divestitures." For its fiscal 2026 outlook, the company stated it cannot reconcile expected organic net sales growth, adjusted margins, adjusted earnings per share, and related metrics to GAAP equivalents without unreasonable effort, citing uncertainty around non-recurring Infant Formula charges, timing and amount of restructuring charges, and related income tax effects. The filing states these "reconciling items could be significant to the Company's future GAAP results."
