Episode Details

Corning Incorporated (GLW) Q2 2026 — Corning (GLW), the 175-year-old materials-science company that now supplies the optical fiber and connectivity wiring AI data centers, reported Q2 2026 (quarter ended June 30, 2026) before the open on July 28 — and beat. Core EPS of $0.78 topped the $0.75 consensus and rose 30% YoY; core sales of $4.74B beat $4.63B and grew 17%, the ninth straight quarter of YoY growth. Quality improved too: core gross margin +120 bps to 39.6%, core operating margin +190 bps to 20.9%, core ROIC 14.9%. Optical Communications did the heavy lifting — sales +32% to $2.07B (44% of the company) with segment net income +77%, and Enterprise Networks (the data-center piece) up 65%. In the quarter Corning signed a long-term NVIDIA partnership to expand U.S. optical-connectivity capacity 10x and a multiyear, multibillion-dollar Amazon deal. Cash is real: $1.72B operating cash flow and $1.42B adjusted free cash flow, with a $0.28 quarterly dividend and ~$6.4B net debt against $1.7B of quarterly operating cash. And the stock still fell about 15% at the open, from $143.36 to roughly $122 — because Q3 guidance (core EPS $0.85-0.89, sales $4.9-5.0B) landed merely in line, optical is effectively sold out until new capacity ramps in 2027, and GLW was one of the most crowded AI-infrastructure trades on the tape after a ~190% run to a June high near $272. Our owner-earnings DCF on a ~$3.5B/yr base, blending a steady +11%/yr path and the +19%/yr Springboard path at a 9% discount rate, lands fair value near $155 versus ~$122 today — roughly 27% upside, with the market effectively paying only the steady case. Our call: BUY, 3/5 — the pullback is the gift, but it is still a premium multiple on a business whose near-term growth is capacity-gated. Wall Street rates GLW a Buy with an average target near $215 (~76% upside), so we AGREE on direction but are far more measured. Corning beat, and the stock fell 15%. That is the whole episode in one sentence. GLW is a 175-year-old materials-science company — specialty glass, ceramics, optical physics — that has quietly become one of the most strategic suppliers to the AI build-out, making the optical fiber, cable and connectivity that link GPUs and racks inside data centers. Q2 2026 (ended June 30): core EPS $0.78 vs $0.75 expected, up 30% YoY; core sales $4.74B vs $4.63B expected, up 17% — the ninth consecutive quarter of year-over-year growth. Core gross margin expanded 120 bps to 39.6% and core operating margin 190 bps to 20.9%, so this was operating leverage, not just volume. Optical Communications rose 32% to $2.07B — about 44% of sales — with segment net income up 77% and Enterprise Networks up 65%. And it is contracted, not hoped-for: NVIDIA signed a long-term partnership for Corning to expand U.S. optical-connectivity capacity tenfold, and Amazon signed a multiyear, multibillion-dollar agreement. The rest of the portfolio is ballast: Glass Innovations $1.46B (+1%), Automotive $0.47B (+2%), Solar/Hemlock $0.44B (+90%, still a small loss during a plant upgrade), Life Sciences and Emerging $0.29B (-15%). So why the 15% gap down? Three reasons. The Q3 guide — core EPS $0.85-0.89 against an $0.85 consensus, revenue $4.9-5.0B — was merely in line, and for a stock up ~190% on the year that reads as a disappointment. Positioning: GLW was among the most crowded AI-infrastructure trades, with JPMorgan flagging valuation and Morgan Stanley noting that sold-out optical caps near-term upside. And the tape: AI-infrastructure names had been selling off for weeks. The result is a genuinely accelerating business now trading roughly 55% below its June high near $272. On the numbers: operating cash flow $1.72B, adjusted free cash flow $1.42B even while capex ramps (partly funded by NVIDIA and Amazon customer prepayments), a $0.28 quarterly dividend (~0.9% yield), and about $2.5B cash against $8.9B debt — around $6.4B net debt, very manageable. The Springboard plan targets a $20B annualized sales run-
