Western Digital stock jumps on S&P upgrade as debt paydown hits filings — what to watch next

New York, Feb 25, 2026, 18:01 EST — After-hours

  • Western Digital finished Wednesday’s session up 7.5%, though the stock dipped after the bell.
  • S&P Global Ratings bumped the hard-drive maker up to investment grade, following a recent cut in its debt load.
  • The filing showed 2029 and 2032 notes were redeemed, and a preferred share class is now gone.

Western Digital Corp jumped 7.5% to finish at $290.95 Wednesday, then slipped around 0.7% after hours as the market processed a credit-rating bump tied to the latest balance-sheet streamlining.

That matters: “investment grade” sits just above junk status, and breaching that threshold opens doors to more bond buyers. For companies tapping debt markets, it can also mean cheaper borrowing down the line.

This comes as investors rush to favor hardware suppliers that consistently generate cash, rather than simply chasing AI-driven growth narratives.

Western Digital disclosed in an SEC filing that it has wiped out its Series A convertible perpetual preferred stock following a mandatory conversion, leaving no preferred shares on the books. The company also said it redeemed all of its 2.850% senior notes due 2029 and 3.100% senior notes due 2032, having deposited enough with the trustee to cover both the redemption price and accrued interest.

S&P is sticking with a stable outlook for Western Digital, citing steady demand for hard disk drives and solid cash flow generation, according to Investing.com. The ratings agency figures Western Digital will keep a net cash position and just $1.6 billion in convertible notes — that’s debt eligible for share conversion — while also leaving its revolving credit facility untapped.

Chief Legal Officer Cynthia Tregillis unloaded 438 shares across two trades on Feb. 23 and Feb. 24, according to a separate Form 4. The sales were made under a pre-set Rule 10b5-1 plan.

Western Digital shares had slipped in the previous session, ending Tuesday at $270.57.

Wall Street finished in positive territory, lifted by fresh gains in tech. Investors seemed reassured after Nvidia posted solid numbers following the close, Reuters said.

The swing isn’t one-way. Western Digital’s stock has seen its share of volatility, and even with a credit upgrade, it’s hardly shielded from weaker data-center demand, softening prices, or an AI sentiment pullback if buyers slam the brakes on spending.

Management heads to Morgan Stanley’s Technology, Media & Telecom Conference on March 3, hitting the stage at 10:45 a.m. ET. Investors are tuning in for any signals on demand trends, pricing shifts, and what’s next for the company’s capital structure.

  • Bathtub ring hints at ancient Martian ocean contours, scientists say
    April 16, 2026, 3:02 AM EDT. New data from NASA's Mars Global Surveyor and other missions strengthen the case that Mars hosted an ancient northern ocean. Researchers identify a ring-like boundary-a Martian bathtub ring-that may mark a coastline and define a broad coastal shelf. Lead author Abdallah Zaki of the University of Texas says rivers dumped sediment, waves rearranged it, and sea levels rose and fell as the ocean fluctuated. The study, published in Nature, compares Martian topography with Earth's continental shelves and estimates the ocean once covered about a third of the planet, about 13% of Earth's ocean area. The work builds on earlier shoreline hints and radar findings from China's Zhurong rover. The water's fate remains debated as Mars cooled and dried.
