AMSTERDAM (Reuters) – Dutch specialty chemicals maker DSM on Tuesday beat analyst expectations with a 10% jump in first-quarter core profit to 487 million euros ($511 million), as demand for its food ingredients and materials remained strong despite elevated prices. Analysts in a company-compiled poll on average had predicted adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) would rise to 466 million euros, from 441 million a year before.
