Vulcan Materials (VMC)

The sleeper story is that Vulcan's cost structure is quietly becoming best-in-class through technology deployment - unit costs fell 2% during a volume surge that should have spiked costs. The obvious headline is strong volume recovery, but this masks pricing deceleration and growing dependence on public infrastructure spending. The binding constraint is residential demand destruction from affordability crisis, which forces VMC to rely entirely on data centers and highways for growth. Most revealing quote: 'Single-family will continue to be challenging until we get some affordability issues behind us.' My view changes if mortgage rates drop below 6% or if private nonres acceleration proves sustainable beyond data centers.
