After the regular trading session ended, a handful of public companies recorded material share-price moves following earnings releases and regulatory news.
Hewlett Packard Enterprise (HPE)
Hewlett Packard Enterprise led the group, with shares jumping 35% in after-hours trading after gaining roughly 9% during the regular session. The move followed a sizable second-quarter beat: HPE reported earnings per share of $0.79 and revenue of $10.7 billion. Management issued markedly higher guidance for both the third quarter and full fiscal 2026, and those updates surpassed Wall Street expectations across the board, supporting the sharp after-hours rally.
Credo Technology Group Holding (CRDO)
Credo Technology Group Holding fell about 12% in extended trading despite reporting a fourth-quarter EPS of $1.16 and revenue of $437 million, both of which topped analysts' estimates. The connectivity solutions provider offered revenue guidance for the first quarter of fiscal 2027 in a range of $465 million to $475 million, a figure that narrowly exceeded consensus. Even with the beat and slight guidance upside, the stock declined after hours.
Fulcrum Therapeutics Inc. (FULC)
Fulcrum Therapeutics plunged 30% after announcing it will discontinue its pociredir program for sickle cell disease. The decision followed feedback from the U.S. Food and Drug Administration raising concerns about potential malignancy risks associated with the program. In response to the regulatory setback, the biopharmaceutical company initiated a strategic review to evaluate next steps, explicitly including the possibility of a merger or acquisition among the alternatives under consideration.
Abivax (ABVX)
Shares of Abivax climbed 20% after the company reported positive Phase 3 results for its ulcerative colitis treatment obefazimod. The trial successfully met its primary endpoint and all key secondary endpoints. Both once-daily dose levels achieved clinical remission rates above 50% at Week 44, significantly outperforming placebo in the ABTECT maintenance trial, according to the reported data.
Microchip Technology Inc. (MCHP)
Microchip Technology rose 6% after emphasizing strong momentum in its Data Center Solutions business unit. That unit posted revenue growth of 62.9% in the March 2026 quarter. Microchip said the Data Center Solutions unit generated $302.7 million in calendar year 2025 and expects roughly 65% growth to reach about $500 million in calendar year 2026, figures the company disclosed.
These after-hours moves underscore how quarterly results, guidance and regulatory feedback can trigger divergent investor reactions across sectors, from enterprise technology and semiconductors to biotechnology and specialty pharmaceuticals.
