Western Digital Corp. stock (ISIN US9581021055) closed at USD 411.96 on the Nasdaq on September 15, 2026, down 3.5 percent from the prior session as memory-chip names weakened across the United States market.

Convertible notes redemption reshapes financing mix

As The Globe and Mail reported on September 15, 2026, Western Digital announced on September 14, 2026 that it will redeem all USD 109.5 million outstanding of its 3.00 percent Convertible Senior Notes due 2028 on November 16, 2026 at 100 percent of principal plus accrued interest, removing this layer of debt from its capital structure.

According to the same release cited by The Globe and Mail, noteholders may convert their holdings up to November 12, 2026 at a fixed conversion rate of 26.5231 shares per USD 1,000 face value, with Western Digital settling principal in cash and any excess value in common shares, a structure that could modestly increase the share count while cutting interest expense.
