The shares are equivalent to a stake of about 5.9% in Grupo Heineken, the Mexican company said in a statement. FEMSA announced in February an offering of around 3 billion euros worth of common shares in Heineken N.V. and Heineken Holding N.V, after saying it would sell its 14% stake in the European company over the next three years.

Filings later showed FEMSA had sold some of the shares. Heineken bought around 1 billion euros of the shares across both of its entities, while American tycoon Bill Gates bought 10.8 million shares - or a 3.76% stake - in the Dutch beverage giant from FEMSA.

FEMSA also announced Tuesday a simultaneous offer of up to 250 million euros of bonds exchangeable for shares of the Dutch brewer due in 2026.

The new bonds "will be consolidated and form a single series" with the ones issued in February for around 500 million euros at a rate of 2.625% and maturing within two years, it said.FEMSA's shares on the Mexican stock market fell 0.26% after the announcement, after an initial 0.04% gain. They still outperformed the main Mexican stock index which fell 1.4% on Tuesday.
