Corning (GLW)

The desk's stance

On our research list, not on the slate.

What the company does

Makes the cover glass on every iPhone and Apple Watch. Apple committed $2.5B in 2025 to Corning’s Harrodsburg, Kentucky plant so that all of it is made in America — the showcase of Apple’s $600B US-manufacturing pledge and its tariff shield.

In short: Specialty glass and optical connectivity. Category: Optical Infrastructure & Specialty Glass. Sector: Technology, Electronic Components.

Our current thesis

Updated Oct 12, 2026

The thesis

  • Hyperscaler multi-billion-dollar optical interconnect contracts accelerate high-density fiber demand for AI data centers.
  • Four straight quarterly EPS beats confirm improving operating leverage and manufacturing capacity scaling.
  • Upfront customer co-funding and prepayments de-risk multi-year manufacturing capital expenditure ramps.

Risks

  • Forward P/E of 35.8x trades at a sharp premium to AVGO and TSM.
  • Net margin of 11.2% significantly lags hardware and semiconductor peers despite AI tailwinds.
  • Capital-intensive optical expansions expose cash flows to carrier or hyperscaler capex digestion.

What we're watching

  • Q3 2026 earnings on October 27, 2026, targeting core EPS of $0.85 to $0.89.
  • Operating cash flow conversion from multi-billion-dollar hyperscaler supply agreements with Meta and Amazon.
  • Technical support consolidation and volume stabilization around the $150 to $160 level.

Latest

Corning trades at $156.68, down 42% from its 52-week high of $271.78 following a multi-month pullback. Q2 2026 revenue rose to $4.51 billion with four consecutive quarters of expanding EPS beats driven by generative AI optical demand. However, a forward P/E of 35.8x and trailing net margin of 11.2% maintain valuation friction against more profitable peers.

Key numbers

As of Oct 16, 2026: market cap $113.7B · revenue growth +16.6% year over year · gross margin 36.4% · net margin 11.2% · forward P/E 30.2 · next earnings Oct 27, 2026.
