Corona and Modelo Are Shrinking While Pacifico and Victoria Are Booming. Here's What That Means for Constellation Brands Stock.

STZ beat Q2 earnings expectations with 6% organic revenue growth, but the quarter's composition tells a more complicated story: its two flagship beer brands are shrinking while smaller labels carry the growth.

Corona depletions fell 5% and Modelo depletions fell 2%. Those declines sit alongside outsized gains from Pacifico, up 19%, and Victoria, up 15%. The net result: STZ gained 0.8% in overall market share.

The wine and spirits segment also delivered strong growth, which the company attributed to repositioning its portfolio toward premium brands.

Interpretation: the headline beat masks a mix shift. Growth is coming from brands that are smaller than the two that anchor the beer portfolio, so the earnings quality question centers on whether Pacifico and Victoria can keep expanding fast enough to offset flagship erosion. The market share gain suggests the portfolio is outperforming the category overall, but that is a different claim than the core brands holding steady.
