Supply-chain alpha

A1

TSMC's contribution to Pinnacle West's load is currently flat year-over-year, meaning even the current robust 9.6% sales growth is driven by diversification (residential and smaller C&I) and not the big fab lines yet; the main TSMC ramp is pending.

“notwithstanding the robust year-over-year weather normalized sales growth we've seen, the TSMC FAB contribution is relatively flat year-over-year.”
Ted Geisler
A2

Pinnacle West's 20,000-acre economic corridor and an additional 30 million sq ft mixed-use development (Halo Vista) surrounding TSMC implies a significant, long-term increase in demand for a wider set of infrastructure and utility services beyond just Pinnacle's core growth.

“Nearly 20,000 acres of surrounding land are now in various stages of planning and development, giving rise to an entirely new economic corridor in the region.”

Pinnacle West's 20,000-acre economic corridor and an additional 30 million sq ft mixed-use development (Halo Vista) surrounding TSMC implies a significant, long-term increase in demand for a wider set of infrastructure and utility services beyond just Pinnacle's core growth. — The ripple effect of TSMC's investment will drive sustained, robust demand for power and construction, underpinning a multi-year capex cycle.
