Corning Incorporated quarterly margin chart

I'll create a quarterly margin chart for Corning Incorporated (GLW). Let me load the relevant financial data first.

Now let me compute the quarterly margin metrics.

The date column needs to be converted to datetime first.

Now let me display the chart and table.

Data MAX

Corning Incorporated (GLW) — Quarterly Profit Margins

The chart and table show GLW's quarterly gross, operating, EBITDA, and net margins from Q2 2021 through Q1 2026.

Key observations:

  • Gross margin has been the most stable of the four, generally oscillating in the 30%–38% range. It dipped to a low of ~26.9% in Dec 2022 and has since recovered, running in the mid-30s through 2025–2026 (latest: 36.9% in Mar 26).
  • Operating margin shows the most cyclicality — it compressed sharply through 2022–2023, hitting a trough of ~2.5% in Dec 22 and Dec 23, reflecting the well-documented optical-communications and display destocking cycle.
  • Net margin also bottomed around breakeven/negative in late 2022 and late 2024 (Dec 24 was -3.5% due to a non-operating charge), and has rebuilt to ~9–13% in 2025.
  • 2024–2025 inflection: A clear margin recovery is visible from late 2024 onward, with operating margin expanding from ~6% in Jun 24 to ~16% in Dec 25 as the display business normalized and enterprise networking demand returned.
  • Revenue growth has also re-accelerated, from ~$3.0B/qtr trough in 2023–2024 to $4.0–4.2B in the most recent three quarters — putting gross profit dollars at record levels.

Let me know if you'd like to overlay revenue, add a TTM view, or compare margins against peers (e.g., AOSL, CDW, or AVGO-related fiber names).

Data 1Y

Corning Incorporated (GLW) — 1-Year Price Chart

The chart above shows GLW's daily adjusted close from Jun 2025 through Jun 2026 (latest data point: Jun 8, 2026 at ~$50–55 range based on the data).

A few quick observations from the series: - Started the period around $50 in mid-June 2025 - Rallied into late summer/early fall 2025, then consolidated - Notable volatility into year-end 2025 as optical/AI-related names saw wide swings

Let me know if you'd like: - A longer timeframe (2Y, 5Y, or max) for a multi-year trend view - A comparison vs. a peer (e.g., AOSL, AVGO, LRCX, or the S&P 500) - A normalized view (rebased to 100) to compare percentage returns - Volume overlaid on the price chart

10 year chart

I'll load 10 years of price data and display the chart.

Data 10Y

Corning Incorporated (GLW) — 10-Year Price Chart

The chart above shows GLW's weekly adjusted close from June 2016 through June 2026.

Key phases visible on the 10Y chart:

  • 2016–2017 (~$15–$32): Sharp post-Fiber-to-the-Home run-up peaking around mid-2017 as the broadband buildout story drove a multiple expansion.
  • 2018–2020 (~$25–$35 down to ~$20): Multi-year derating as LCD glass pricing deteriorated and the stock chopped sideways, with a COVID-driven drawdown to the low $20s in Mar 2020.
  • 2020–2021 (~$20 → ~$44): Strong recovery into the reopening and the peak of the 5G/fiber cycle, with the stock nearly doubling.
  • 2022–2024 (~$44 → ~$30s): A prolonged downtrend as optical/display destocking hit revenue and margins (consistent with the margin compression you saw earlier). Stock bottomed in the low-$30s.
  • 2024–2026 (~$30s → ~$50+): Recovery leg as the display business normalized, Gen-AI optical demand emerged, and margins re-expanded.

Over the full 10 years, the price has roughly tripled (from ~$16 in mid-2016 to ~$50+ in mid-2026), but the journey was a classic cycle: parabolic first-half run, multi-year derating, then re-rating.

Let me know if you'd like a log-scale version, a normalized view (rebased to 100) to compare cumulative returns, or an overlay with the S&P 500 or a peer (e.g., AOSL, LRCX, AVGO).

reveneue and net income quarterly, add capex also in that

I'll load the additional cash flow data and combine everything into one quarterly view.

Corning (GLW) — Quarterly Revenue, Net Income & CapEx

Key takeaways from the chart and table:

  • Revenue trend: Held in a tight $3.4–$3.7B band from 2021 through mid-2022, then declined for ~6 quarters to a $2.97B trough in Mar 2024, before re-accelerating to a record $4.22B in Dec 2025. The latest quarter (Mar 26) came in at $4.14B — i.e., revenue is now ~$700M/quarter higher than the 2021 peak.

  • Net income volatility: Far more cyclical than revenue. Slipped into losses in Dec 2022 (-$36M) and Dec 2023 (-$40M), and was pressured again in Sep 2024 (-$117M, one-time charge). Has since rebuilt to $540M in Dec 2025, the highest quarterly print in the dataset.

  • CapEx profile: Notably countercyclical. CapEx spiked to $623M in Dec 2021 (peak optical/wireless buildout) and ran at $400M+ through 2022. Management then cut CapEx as revenue weakened — down to $208M in Mar 2025, the lowest in the series. CapEx has now stepped back up to $332–$432M alongside the Gen-AI optical capacity build, but is still well below 2021–2022 levels. This "CapEx discipline" is a key piece of the bull thesis.

  • Free cash flow proxy (Op CF − CapEx): Op CF was negative in Mar 2023 (-$49M) as working capital reversed, but has otherwise been positive and well above CapEx in most quarters — supporting the capital return story (buybacks + dividends).

  • Capital intensity is rising again: Latest three quarters' CapEx ($308M / $334M / $432M averaging ~$358M) is roughly 2x the Mar–Jun 2024 lows, signaling management is investing ahead of the AI optical demand pull.

Let me know if you'd like a bar chart of the same data, a FCF column added, a CapEx / Revenue % line, or a TTM rollup view.
