Capital structure and capital return

• January 27, 2025 (8-K filed January 29, 2025, 0000707549-25-000011). Lam entered a Third Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A. as administrative agent. It raises the unsecured revolving facility from $1.5 billion to $2.0 billion, with an option to expand by up to $750 million. The facility matures January 25, 2030. This predates fiscal 2026 and is included because it sets the liquidity backstop for the year.
• March 2026, senior notes. The cash flow statement in the April 22, 2026 release (0000707549-26-000020) and the June 2026 release (0000707549-26-000033) shows principal debt payments of $751.2 million in the March 2026 quarter. The company's 10-Q for that quarter (0000707549-26-000022) states that the $750.0 million of 3.75% Senior Notes due March 15, 2026 were settled at maturity with cash on hand. No replacement debt issuance appears in the filings.
• Dividends. The quarterly dividend declared per share was $0.23 in the June 2025 quarter and $0.26 in the March and June 2026 quarters (0000707549-26-000033). Fiscal 2026 declared dividends were $1.04 per share, against $0.92 in fiscal 2025.
• Share repurchases. Treasury stock purchases were $246.6 million in the June 2026 quarter and $1,162.8 million in the March 2026 quarter (0000707549-26-000033). The 10-K (0000707549-26-000037) reports a $200.0 million accelerated share repurchase agreement entered March 11, 2026.
