Check out the companies making headlines after the bell : MillerKnoll — The furniture stock plunged 17%. MillerKnoll posted fiscal third-quarter adjusted earnings of 43 cents on revenue of $926.6 million. That reflected a year-over-year decline of 2% for adjusted earnings and an increase of 6% for revenue. The company warned of a roughly $8 million to $9 million impact in the fourth quarter tied to the Middle East conflict, stemming from minimal expected shipments to that part of the world as well as higher logistics costs.

However, Karman’s $134.5 million revenue came in above the $132.6 million consensus estimate. Celcuity — The biotechnology stock shed 2%. The company reported a loss of 97 cents per share in the fourth quarter, which was narrower than the expected consensus of $1.04 a share, per FactSet. Research and development expense of $37.6 million came in line with analysts’ expectations.
