As the trading day wrapped up on March 25, several notable stocks saw significant movement in after-hours trading, following their earnings reports and related announcements. Here is a breakdown of the companies making headlines after the bell:
MillerKnoll Falls 17% Despite Revenue Growth
MillerKnoll, a prominent furniture manufacturer, experienced a steep 17% drop in its stock price after hours. The company reported fiscal third-quarter adjusted earnings of 43 cents per share on revenue of $926.6 million. While revenue rose 6% compared to the same period last year, adjusted earnings declined by 2%.
Investors appeared concerned about MillerKnoll’s outlook. The company issued a cautionary note regarding the impact of ongoing conflict in the Middle East. Specifically, MillerKnoll warned of an expected $8 million to $9 million negative effect on Q4 results, stemming from minimal shipments to the region and increased logistics expenses tied to the geopolitical situation.
Karman Slightly Up on Mixed Earnings Report
Shares of Karman, an aerospace and defense firm, edged higher in after-hours trading despite mixed earnings results. The company posted fiscal fourth-quarter adjusted earnings of 11 cents per share, just below the consensus estimate of 12 cents per share compiled by FactSet.
However, Karman’s revenue of $134.5 million surpassed analyst expectations, which had set the bar at approximately $132.6 million. The modest beat on revenue appeared to underpin the stock’s slight gains after the market closed.
Celcuity Shares Down 2% Following Quarterly Loss
Biotechnology company Celcuity saw its shares decline by 2% after releasing its fourth-quarter results. The company reported a loss of 97 cents per share, which was narrower than the consensus estimate of a $1.04 per share loss according to FactSet.
Celcuity’s research and development spending totaled $37.6 million, aligning with analyst expectations. Despite the somewhat better-than-anticipated loss figure, the stock declined modestly in extended trading.
Worthington Steel Drops 15% on Earnings Decline
Worthington Steel’s stock plummeted nearly 15% following the release of its fiscal third-quarter numbers. The steel processing company posted adjusted earnings of 27 cents per share—a decrease from 35 cents per share reported in the same quarter a year ago.
This decline in profitability weighed heavily on investor sentiment, contributing to the sharp selloff in after-hours trading.
Investors and market watchers will be closely monitoring these companies as they navigate external challenges and strive to meet or exceed analyst expectations in upcoming quarters.
