Daily history updates are delayed. Available history through 2026-10-23 remains visible; a current quote does not establish that daily history has been updated.
Requests to the historical-data source are rate limited, delaying daily-price updates. Existing verified periods are retained; trading days not yet retrieved are not fabricated.
The history starts with the provider’s first actual observation; this starting point is not a verified initial listing date.
The earliest available price is not proof of the listing date. Coverage since listing remains unverified.
Trading dates checked for 2000-09-19 — 2026-10-23: all 6,563 expected dates are present. Complete dates do not establish independent verification of every price.
Security basis: The current security identity has been checked. Continuity with earlier issuers has not been independently verified; listing-date coverage is shown separately. Historical closes use the provider's split adjustments and exclude dividend distributions. Full-history adjustment factors have not been independently recalculated. Price changes do not represent total returns including dividends.

Each panel has its own value axis; dates and the cursor are synchronized. Dense daily plots retain the first, last, highest and lowest observations in each pixel interval. The cursor, data table, CSV and statistics still use all original values. Operating data appear only on their observed dates; other dates are left blank. US daily prices are checked against the verified 1997–2027 trading calendar. A missing expected trading day breaks the line; weekends and recorded exchange holidays do not. Annual observations retain annual frequency; guidance and scenarios are labeled separately. Operating data are positioned at the actual period end, which is not necessarily the date of public disclosure. Drag within the chart to zoom and move the range window below to pan.

Gross profit / revenue × 100
Company-wide reported gross margin is not the margin of any individual product, segment or order. Uses explicit period boundaries, the reported currency and the selected SEC concept. Cumulative reconstructions retain signed inputs. The filing-version date is not a verified first-disclosure date. Missing values are neither replaced with zero nor interpolated into daily observations.

Operating income / revenue × 100
Uses reported operating income, not adjusted earnings. Differences in expense classification can still limit comparisons across companies. Uses explicit period boundaries, the reported currency and the selected SEC concept. Cumulative reconstructions retain signed inputs. The filing-version date is not a verified first-disclosure date. Missing values are neither replaced with zero nor interpolated into daily observations.

Selected net-income concept / revenue × 100
May reflect differences in non-controlling interests, taxes and one-time gains or losses. The specific net-income concept is retained for each observation.

Uses explicit period boundaries, the reported currency and the selected SEC concept. Cumulative reconstructions retain signed inputs. The filing-version date is not a verified first-disclosure date.

The excerpts below come from this record. Verify signed status separately from actual completion.
The amount associated with a relationship cannot substitute for the company's revenue, earnings or stock-price impact. Applies to this relationship; the original document determines the specific legal entities and attribution.
Analytical framework, not a realized impact
INTC supplies products or services to UMC; a customer list is not an irrevocable order.
Verify purchasing, inventory preparation, delivery and quality acceptance; monitor alternative supply and capital tied up in inventory.
Assess purchasing costs, gross profit and working capital; verify supply volumes and revenue recognition separately.
First verify the sustainability of earnings and cash flows, then compare valuations; do not infer share-price upside directly from a partnership announcement.
Cross-check relationship events against subsequent disclosures of company revenue, costs, working capital and cash flows; movements in the same direction alone do not establish causation.
Metrics test operating processes; an overall change cannot be attributed to a single relationship. Expand the definitions to check calculation methods and their applicable boundaries.

Key relationships were reviewed using public information available through 2026-10-23. Historical relationships have not all been individually reverified. Their original dates are retained; delisted entities remain in the relationship archive but are excluded from market-cap weights. Review coverage through 2026-10-23.
Signed status does not mean that the full amount has been paid or that capacity has been delivered. Assess contract value, period revenue, investment, loans, prepayments and guarantee caps separately; do not sum them as a single exposure. Distinguish total power capacity from critical IT load. Company-level metrics cannot be attributed directly to an individual relationship.
Source facts and operating implications are distinguished, with forecasts and conditional scenarios identified as such. Missing relationships mean that this graph has no record of them. Data version 60aad2cdea0eff4f82e9dafe344d1e57aa2b950269b621d7e5bddfef10520644.
