Companies in Ireland that spend the most on R&D
Research and development expense is what the company charged to R&D in the income statement for the year. Most companies report no R&D at all — the line is absent rather than zero — so this ranking covers the roughly 40% of filers that do. Figures are for fiscal year 2025 and are read directly from each company's SEC filings; the source column on every row links to the document.
Medtronic (MDT) tops the list with $2.9B in r&d expense for fiscal 2025, ahead of PDD Holdings ($2.4B) and Accenture ($817M). The top 10 together report $9.7B in r&d expense; the gap between #1 and #10 is ×10.52. 16 companies in Ireland report r&d expense, 1.3% of the 1270-filer universe. The last place on the list, Dole, comes in at $9.2M.
