SEC 8-K and 6-K filings classified by Claude with reasoning, plus Form 4 insider transactions. Ingested from EDGAR’s filing stream in near-real time, reconciled overnight.
Open-market buys and sells only — the deliberate trades. Zero here doesn’t mean no filings: grants, option exercises and tax withholding (below) are compensation, not market trades.

Risk exposure broadened and deepened across five distinct themes — regulatory/export controls, supply chain, geopolitical, cybersecurity/AI, and capital structure — with no meaningful offsets. China revenue already contracted 30 percentage points YoY under tightening export controls, rare earth and DRAM shortages carry quantified margin impact in FY2027, and a newly disclosed $2B interest rate swap adds a concrete balance-sheet vulnerability. The cumulative worsening is pervasive rather than concentrated, meeting the bar for a major shift in the overall risk picture.

Fiscal period ending 2025-06-30 versus 2024-06-30 — view filing on EDGAR →
The company faces a materially worsened risk profile driven by converging geopolitical and regulatory pressures: active U.S. tariffs are already hitting cost of revenues and triggering order cancellations, new BIS export controls have cut China revenue from 43% to 33% with backlog harm now disclosed, and Chinese rare earth export controls introduce a fresh supply chain vulnerability. A modest balance sheet improvement — debt down $750M and revolver capacity doubled — provides partial offset but does not meaningfully counterbalance the breadth of operational and regulatory deterioration. Tax law changes (OBBBA, Singapore Pillar Two) and mandatory ESG compliance obligations add further cost and complexity headwinds entering 2026.

KLA's Board declared a quarterly cash dividend of $0.23 per share, payable September 1, 2026 to shareholders of record as of August 17, 2026. This is a routine but material dividend declaration that affects shareholder value and is disclosed via press release attached as Exhibit 99.1.
View raw filing on EDGAR →KLA Corporation issued a press release on July 28, 2026 announcing selected financial and operating results for its fourth quarter and full fiscal year 2026, including GAAP net income of $1.36 billion and $4.83 billion respectively, GAAP diluted EPS of $1.04 and $3.66 respectively, and total revenues of $3.66 billion and $13.58 billion respectively. The press release includes detailed financial statements, segment information, and forward guidance for Q1 FY2027, which is the standard format for a quarterly earnings release disclosure under Item 2.02.
View raw filing on EDGAR →KLA Corporation announced and effected a ten-for-one forward stock split through a Charter Amendment to its Restated Certificate of Incorporation, which became effective on June 11, 2026. While this is a structural capital event that affects share count and authorized shares, it does not fit neatly into the standard taxonomy categories (not an earnings release, executive change, M&A, restatement, auditor change, impairment, covenant breach, or cybersecurity incident). Stock splits are material to investors as they affect share price, trading mechanics, and capitalization structure, warranting disclosure as a material event outside the more specific categories.
