Micron Pops, Kratos Drops: After-Hours Movers to Watch

Several high-profile stocks made sharp moves after the closing bell on Wednesday, with earnings beats and strategic surprises driving after-hours volatility.

Micron Technology (MU) surged nearly 4% after the chipmaker posted impressive fiscal Q3 results. Earnings landed at $1.91 per share on $9.3 billion in revenue, crushing analyst expectations of $1.60 and $8.87 billion, respectively. Even more bullish? The company’s Q4 guidance came in stronger than Wall Street anticipated.

H.B. Fuller (FUL) climbed over 6% following its latest earnings report. The adhesives manufacturer reported $1.18 per share, beating the $1.08 estimate, and reaffirmed a solid full-year earnings forecast.

Not everyone was celebrating. Kratos Defense & Security Solutions (KTOS) tumbled nearly 7% after announcing a $500 million public offering of common stock—a move that often signals dilution to investors.

MillerKnoll (MLKN) had a more complicated day. The stock jumped 9% on $961.8 million in quarterly sales, up over 8% year-over-year. But profits were down: EPS fell from 67 cents to 60 cents, suggesting margin pressure even as revenues climb.

Finally, Jefferies Financial (JEF) dipped over 2% after posting 40 cents EPS, missing the 44-cent forecast, though revenue of $1.63 billion slightly beat estimates.


​Bottom line: Chipmakers and industrials stole the show after hours, while capital-raising and earnings misses brought volatility to others. As earnings season ramps up, expect more fireworks in extended trading.
