Values are as tagged by the issuer in XBRL. Revenue for banks and insurers is net of interest expense where that is the reported line. Fiscal years that do not follow the calendar are shown by their period-end date. No price, market cap, or valuation multiple is shown because Yield Theory does not republish unlicensed market data.

Diluted EPS is the earnings figure behind the price-to-earnings ratio; the P/E multiple compression calculator shows how a change in that multiple moves a share price. Shares outstanding multiplied by the share price gives market capitalization.

What investors should watch in MCK

  • ◆Medicare and drug-pricing policy
  • ◆Demographics and an aging population
  • ◆GLP-1 and obesity-drug demand

Key questions for the MCK thesis

Each question starts with what the filings show, then why it matters. None of these is a rating or a forecast.

Does MCK's reported profit turn into cash?

Operating cash flow was $6.2B, 1.29 times net income of $4.8B, for the fiscal year ended March 31, 2026.

Cash from operations exceeded reported earnings. Non-cash charges such as depreciation, amortization and stock-based compensation usually explain the gap; the cash-flow statement shows which.

How much of MCK's revenue is left as profit?

Net income was 1.2% of revenue for the fiscal year ended March 31, 2026, based on revenue and net income reported for the same period.

Net margin reflects the business model as much as execution, so compare it with companies in the same SEC industry and read the income statement for one-time items before treating it as a run rate.

When does McKesson Corporation's fiscal year end?

The SEC lists McKesson Corporation's fiscal year end as March 31, not December 31. The latest annual figures here run from April 1, 2025 to March 31, 2026.

Annual results cover a different 12 months from calendar-year peers. Align periods before comparing growth or margins across companies.
