Corning Incorporated — 2021 Form 10-K Summary
Business context and reporting period
Corning is a materials-science manufacturer serving optical communications, mobile and consumer electronics, display, automotive emissions-control, and life-sciences markets.

This Form 10-K covers the fiscal year ended December 31, 2021, filed February 14, 2022. The filing is annual rather than a standalone fourth-quarter report; the source does not provide a separate Q4 income statement or cash-flow presentation.
Financial performance and key metrics
| Metric | 2021 | 2020 | Change |
|---|---|---|---|
| Net sales | $14.082 billion | $11.303 billion | +25% |
| Gross margin | $5.063 billion; 36% | $3.531 billion; 31% | +43%; margin +5 points |
| Operating income | $2.112 billion | $509 million | +315% |
| Net income attributable to Corning | $1.906 billion | $512 million | +272% |
| Diluted EPS | $1.28 | $0.54 | +137% |
| Core net income | $1.811 billion | $1.237 billion | +46% |
| Core diluted EPS | $2.07 | $1.39 | +49% |
| Net cash from operations | $3.412 billion | $2.180 billion | +$1.232 billion |
| Capital expenditures | $1.637 billion | $1.377 billion | +$260 million |
| Cash and cash equivalents | $2.148 billion | $2.672 billion | -$524 million |
| Total debt | $7.044 billion | $7.972 billion | -$928 million |
Operating cash flow less capital expenditures was approximately $1.8 billion. Cash used in financing activities was $2.452 billion, primarily reflecting debt repayments, the preferred-stock-related share repurchase, common-stock repurchases, and dividends.
Working capital was $2.853 billion, the current ratio was 1.6:1, and total debt represented approximately 36% of total capital. Corning had no commercial paper outstanding and no borrowings under its $1.5 billion revolving credit facility at year-end. Management stated that available cash, operating cash flow, and financing resources were sufficient for operations, capital expenditures, scheduled debt repayments, dividends, acquisitions, and planned share repurchases for the next 12 months.
Segment results and material changes
| Segment | 2021 sales | 2021 segment net income | Sales change |
|---|---|---|---|
| Display Technologies | $3.700 billion | $960 million | +17% |
| Optical Communications | $4.349 billion | $553 million | +22% |
| Specialty Materials | $2.008 billion | $371 million | +7% |
| Environmental Technologies | $1.586 billion | $269 million | +16% |
| Life Sciences | $1.234 billion | $194 million | +24% |
| All Other | $1.243 billion | $(51) million | +167% |
- Display Technologies benefited from mid-teens volume growth and stable pricing.
- Optical Communications grew in carrier and enterprise products, supported by 5G, broadband, and cloud-computing demand.
- Life Sciences benefited from pandemic-response demand, laboratory recovery, bioproduction vessels, and diagnostic consumables.
- Environmental Technologies increased sales of heavy-duty diesel products and gasoline particulate filters.
- Specialty Materials sales increased, but segment income declined 12% because of increased investment in innovation programs approaching commercialization.
- All Other sales benefited substantially from the full-year consolidation of HSG, which had been consolidated only from September 9, 2020 in the prior-year comparison.
Gross-margin expansion reflected higher volume across segments and lower severance and capacity-realignment charges, partially offset by elevated freight, logistics, and raw-material costs. Research, development, and engineering expense declined 14%, primarily because 2020 included a $211 million asset impairment related to discontinued research programs. The 2021 restructuring, impairment, and other charge total was $110 million versus $827 million in 2020.
Guidance, outlook, unusual items, and risks
Management expected 2022 to be another year of growth and strong cash-flow generation, with full-year net sales of approximately $15 billion. Capital expenditures were expected to remain consistent with 2021. On February 2, 2022, the board approved a 13% increase in the quarterly common dividend, from $0.24 to $0.27 per share.
In April 2021, Corning converted its Series A preferred stock into 115 million common shares and immediately repurchased 35 million shares from Samsung Display for approximately $1.5 billion. The transaction reduced net income available to common shareholders by $803 million for EPS purposes; approximately $1.014 billion remained payable at year-end in two installments.
Corning redeemed $625 million of debentures during 2021 and recorded $31 million of bond-redemption losses. Foreign-currency hedging generated a $354 million translated-earnings contract gain, and translation of Japanese yen-denominated debt generated a $180 million gain. These items materially affected reported GAAP earnings and make core measures important for evaluating operating trends.
- COVID-19, supply-chain interruptions, transportation constraints, labor availability, semiconductor shortages, inflation, and higher input costs may reduce shipments or margins.
- Display Technologies generates a significant share of profits and cash flow and remains exposed to pricing pressure, excess capacity, technology shifts, and market-share changes.
- Customer concentration is significant at the segment level; three Display Technologies customers represented 55% of segment sales, while three Environmental Technologies customers represented 77%.
- Corning is exposed to foreign-currency movements, particularly the Japanese yen, South Korean won, Chinese yuan, Taiwan dollar, and euro. A hypothetical 10% adverse currency move would have reduced derivative fair value by approximately $0.7 billion, largely offset by hedged exposures.
- Environmental, intellectual-property, litigation, cybersecurity, geopolitical, trade, tax, and regulatory risks could adversely affect operations and financial results.
- Corning had accrued approximately $55 million for environmental cleanup and related litigation involving 15 active hazardous-waste sites. Management considered a materially higher loss unlikely.
- Corning reported a $350 million non-current receivable for disputed South Korean tax assessments and refund claims, subject to an appeal process. Recovery depends on prevailing in the tax disputes.
Most important facts for investors to verify
- Reconcile GAAP net income of $1.906 billion and diluted EPS of $1.28 with core net income of $1.811 billion and core diluted EPS of $2.07, including the preferred-stock redemption and foreign-currency impacts.
- Assess whether the 2022 sales outlook of approximately $15 billion is supported by sustainable demand, particularly in Optical Communications, Display Technologies, and Life Sciences.
- Monitor freight, logistics, raw-material, labor, and energy inflation and its effect on the 36% gross margin.
- Evaluate Display Technologies pricing, volume, capacity utilization, and customer concentration.
- Review HSG’s contribution to All Other sales and the related customer deposits, deferred revenue, debt, and long-term supply obligations.
- Confirm debt maturities, including approximately $55 million due in 2022, $141 million in 2023, and $293 million in 2024, against expected operating cash flow and planned capital spending.
- Track the remaining Samsung Display share-repurchase payments and the potential 2024–2027 option for Samsung Display to sell additional shares.
- Review the outcome and timing of the $350 million South Korean tax dispute receivable, environmental reserves, and other legal contingencies.
