Western Digital filings document material events for an operating storage company whose common stock trades on the Nasdaq Global Select Market under WDC. Recent 8-K disclosures record quarterly operating and financial results, dividend and capital-structure matters, shareholder voting and governance items, and material agreements.
The filing record also describes security-structure changes, including the mandatory conversion of Series A Convertible Perpetual Preferred Stock into common stock, the Certificate of Elimination for that preferred series, and redemptions or discharge of senior-note obligations. These documents frame WD's public-company reporting around results, debt and equity instruments, governance, and corporate actions following the completed Flash business separation.
