Micron Technology Inc. (MU) did not update its full-year guidance during its presentation at the 53rd Annual JPMorgan Global Technology, Media and Communications Conference. The company reported that the May quarter is tracking well, supported by healthy DRAM and NAND bit shipment growth as consumer and smartphone/PC inventories normalize. Despite this, Micron's shares declined by 2.5% in pre-market trading, following a rebound in the chip sector, as investors had anticipated an upward revision to third-quarter guidance. Meanwhile, Fiserv Inc. (FI) experienced a 13% drop in shares after its CFO indicated that second-quarter volume growth in its Clover business is expected to remain similar to the first quarter's 8% growth. Clover's revenue growth was reported at 27% year-over-year, but the company faces challenges with gateway conversion headwinds expected to peak in the second quarter before easing in the third. Fiserv's market outlook heavily depends on Clover delivering 30% revenue growth in both 2025 and 2026 to meet targets set during its Investor Day.
