Why MTX stock is down today
Minerals Technologies (MTX) fell 4.50% to $72.81 in morning trading on Thursday, marking one of the largest declines in recent weeks. The stock opened at $76.25 but quickly reversed course after hitting an intraday high of $76.48 at market open. The sharp drop followed a string of earnings-related developments and internal sales by top executives.
What Happened
The stock's decline came amid a backdrop of mixed earnings results and downward guidance. The company reported second-quarter sales of $548 million, up 4% year over year, and earnings per share of $1.60, a 3% increase. However, both figures missed estimates, with adjusted EPS of $1.60 falling short of the $1.64 forecast and sales missing the $558.825 million estimate. The company also revised its third-quarter outlook, forecasting GAAP earnings between $1.55 and $1.60, below the $1.75 estimate, and sales of $550 million versus the $562.45 million estimate.
In addition, the stock has been under pressure from recent insider transactions. CEO Dietrich Douglas T and VP Jordan Timothy sold shares on May 14 and May 11, respectively, adding to investor concerns. The stock has also been impacted by the parent company's funding of a $450 million talc personal injury trust from non-debtor affiliates, as part of its Chapter 11 reorganization plan for its subsidiaries.
What The Data Shows
MTX opened sharply higher but reversed quickly, hitting a session low of $72.37 shortly after the open. The stock traded at $72.81 at the time of writing, with a volume of 0.1 million shares, which is 0.3 times the 3-month average. The stock has been volatile recently, rising 3.1% over the past 8 sessions, but remains below its 52-week high of $84.34. The company has a market cap of $2.4 billion, but it remains unprofitable with a trailing twelve-month EPS of -2.17 and a net margin of -3.1%.
What To Watch
Investors will need to monitor the company’s upcoming earnings report and any further developments in its Chapter 11 proceedings. Truist Securities recently raised its price target to $90 and maintained a Buy rating, but the market may react to any additional guidance or operational updates.
