USD lines in millions; EPS per share. Annual columns are fiscal years, labeled by their period-end month (a filer's own fiscal label may differ). “—” is an honest gap: the filer did not tag that line for that period. *TTM (twelve months ended 2026-05-09) is computed from filed periods — latest fiscal year plus newer quarters minus their year-ago pairs; each line’s full trail rides the CSV export. Every column cites its accession in the export. Figures as filed via SEC EDGAR, never estimated.
Answers come strictly from AZO's 10-K filed 2025-10-27, and every answer links the exact passages it used. Questions asking what to do with the stock are refused — that's the point.
Operating income as a share of revenue — what remains after both the direct cost of sales and the operating expenses (R&D, sales & marketing, G&A) that run the business. It measures how much of the gross margin survives the cost of operating the company.
Operating margin = Operating income ÷ Revenue
Each one computed from the same filings and cited the same way.
