Lilly reported $22.965 billion of Mounjaro revenue and $13.542 billion of Zepbound revenue in 2025. By channelling the revenue back to Ireland, the American company saves on tax, and in turn throws off a revenue windfall for the Irish exchequer. Not only should the fact that an American company is paying twice as much tax in Ireland as it does in America, where the revenue is generated, annoy all Americans, but the money is destroying the Irish economy from the inside. If the economy or society becomes overdependent on one sector or company, the economy flatters to deceive. At the standard 12.5 per cent corporation tax rate, it would pay €500,000 × 12.5 per cent = €62,500 in corporation tax.
