MCKESSON CORP MCK

McKesson's current story is led by filed scale, not market theatre. The latest supplied SEC EDGAR financial rail shows $403.43B of revenue from contracts with customers, excluding assessed tax, for the 10-K period ended March 31, 2026. On that same filed basis, McKesson reported $4.76B of net income attributable to parent, $6.21B of operating income and diluted earnings per share of $38.38.

The company sits in the practical machinery of healthcare supply. The supplied 10-K evidence says sales to McKesson's ten largest customers, including group purchasing organisations, accounted for about 73% of total consolidated revenues in fiscal 2026. Its next two largest customers accounted for 11% and 10%. At March 31, 2026, sales to the largest customer represented about 24% of total consolidated revenues and about 21% of total trade receivables. That is the operating reality underneath the ticker: scale, contracts, inventory and a concentrated customer base.

The filing rail gives a fuller balance-sheet and cash picture. McKesson listed $82.32B of assets, $3.98B of cash and cash equivalents, $24.21B of net inventory, and stockholders' equity attributable to parent of negative $2.17B in the 10-K period ended March 31, 2026. It also reported $6.16B of net cash provided by operating activities, $436.0M of payments to acquire property, plant and equipment, a $1.08B increase in inventories, and 124.1M diluted weighted-average shares outstanding.

No chart route, TradingView snapshot or quoted market level is supplied in this evidence pack, so the daily file cannot claim a candle pattern, support zone, breakout or price move. The source route here is SEC EDGAR: the May 7, 2026 8-K says McKesson reported preliminary results for the quarter and fiscal year ended March 31, 2026, while the May 8, 2026 10-K supplies the filed annual numbers. The June 12 proxy materials, annual report and 8-K add governance and annual-meeting context rather than a parsed trading signal.

The latest named developments are filing developments. SEC EDGAR lists a Form 4 dated June 18, 2026, a Form 144 dated June 17, 2026, and a cluster of June 12 materials including the ARS, DEFA14A, DEF 14A and 8-K. The supplied evidence does not parse the transaction details inside the Form 4 or Form 144, so the disciplined read is narrower: insider and securities-sale filing trail exists on the rail, but the economic meaning has not been extracted here.

The proxy adds one corporate operating detail beyond the financials. McKesson said it introduced LEADRx as part of its Leadership Prescription, a framework designed to unlock team potential and meet the speed, complexity and expectations of customers, patients and partners. The Board said embedding those leadership behaviours would support accountability and execution. That claim is corporate language, but it belongs beside the hard customer-concentration facts because this business depends on a small set of large relationships staying functional at scale.
