Sleep Number Faces Securities Fraud Investigation After Stock Collapse

A 22.45% single-day share price drop followed by a subsequent 70% plunge has triggered a formal investigation into Sleep Number Corporation. The law firm Wolf Haldenstein Adler Freeman & Herz LLP is now probing whether the mattress manufacturer’s leadership misled investors regarding the company’s precarious financial position.

The scrutiny follows a disastrous first-quarter earnings report released on May 12, 2026. Sleep Number posted a GAAP loss of $2.19 per share, missing market expectations by a significant margin. Revenue for the period stalled at $318.99 million, also falling short of consensus estimates. Compounding the investor exodus, the company suspended its financial guidance while confirming it had retained Guggenheim Securities to explore strategic and financing alternatives.

Market confidence evaporated as the company signaled it was laying the groundwork for a potential bankruptcy filing. By June 4, the stock had cratered to $0.35 per share, representing a total collapse from its earlier valuation. Shareholders who incurred losses during this period are now being urged to contact Gregory Stone at Wolf Haldenstein to discuss potential class-action litigation and the protection of their remaining interests.
