Technology shares delivered mixed premarket performances Wednesday as investors weighed quarterly results against elevated expectations. Dell Technologies rose 8% after reporting fiscal second-quarter adjusted earnings of $7.04 per share and revenue of $46.97 billion, both above analyst estimates of $4.91 and $44.95 billion. AI-optimized server revenue doubled to a record $16.4 billion, while AI server orders reached $60.9 billion and backlog expanded to $95 billion. Management also raised its full-year fiscal 2027 outlook. MongoDB fell approximately 13% despite second-quarter adjusted earnings of $1.90 per share and revenue of $772 million, above estimates of $1.61 and $734 million. Revenue increased 30% year over year, and the company raised its fiscal 2027 adjusted earnings and revenue guidance, but investors appeared to have expected an even stronger result or found the outlook insufficient relative to the stock's valuation. Palo Alto Networks slipped nearly 2% despite adjusted fiscal fourth-quarter earnings of $1.02 per share, revenue of $3.41 billion and above-consensus fiscal 2027 guidance; it also announced the acquisition of AI-native platform Console. Credo Technology dropped about 9% after beating revenue and earnings estimates and issuing stronger-than-expected second-quarter revenue guidance, as its 68% non-GAAP gross margin narrowly missed the 68.3% consensus. GitLab surged more than 17% in extended trading after exceeding revenue and adjusted earnings estimates and raising its fiscal 2027 outlook. Sirius XM gained more than 3% after Deutsche Bank upgraded the stock to buy with a $45 price target. Vertiv edged lower after announcing a $1.45 billion acquisition of UtilityInnovation Group, including up to $1.15 billion in additional consideration tied to EBITDA targets over 12- and 24-month periods. The market reaction underscored the premium investors are placing on tangible AI infrastructure demand, including power, cooling and connectivity, while software companies face a higher valuation hurdle.
