Feb 12 (Reuters) - Constellation Brands STZ.N said on Thursday it appointed Nicholas Fink as its top boss, replacing Bill Newlands, as the beermaker battles demand pressures.

Fink, who was previously the CEO at the security and digital products firm Fortune Brands Innovations, will take over as the top boss of the Modelo beer maker on April 13. He had served on Constellation's board for the past five years.

Newlands, who joined the company in 2015 and has been at the helm of the company since 2019, will step down from the board in April, but will continue to serve as a strategic advisor over the next several months to help ensure a smooth transition of leadership, Constellation said.

Constellation has been battling weak alcohol sales as Hispanic consumers pull back on purchases amid the Trump administration's crackdown on immigration and a broader economic uncertainty driven by volatile trade policies and rising living costs.

Shares of the company were down 1.5% in extended trade.
