AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.
**Bottleneck theme:** Construction & MEP **Focus:** $EME — EMCOR Group, Inc. EMCOR is, alongside Comfort Systems ($FIX), one of the two large-scale U.S. mechanical/electrical/plumbing (MEP) contractors built for the AI data-center super-cycle. The Q1-Q2 26 prints showed RPO (remaining performance obligations) at a record $15.6B — multi-year forward visibility on contracted work — with mission-critical electrical and mechanical construction now the largest growth driver in the mix. Hyperscaler campuses don't get built on schedule without companies like EMCOR pulling conduit, hanging ductwork, plumbing chilled-water loops, and tying in switchgear at tens of thousands of trades-hours per MW. The investment case is mix shift plus operating leverage: EMCOR's labor base is the moat — tradesmen are a hard cap on industry growth, and EMCOR has spent decades acquiring regional specialists. The bear case overlaps with $FIX: a hyperscaler capex pause, labor-cost inflation outrunning pricing, and a forward valuation that has already rerated significantly from the post-COVID lows. Trades at a relative discount to $FIX with similar end-market exposure but a different mix (more industrial, less pure tech), making it a complementary rather than redundant position.
