MILAN (Reuters) -Luxury sports-car maker Ferrari said on Tuesday its core earnings rose 15% in the first quarter supported by a richer product mix and demand for personalisation of vehicles, but reiterated U.S. tariffs could hit profitability this year

The Italian company said its earnings before interest, tax, depreciation and amortization (EBITDA) amounted to 693 million euros ($784 million), broadly matching an analyst consensus of 689 million euros in a Reuters poll.

Milan-listed shares in the company, which confirmed its forecasts for its full-year results, were down 1% by 1055 GMT.
