Why TMC stock is up today
TMC stock rose 7.21% to $4.01 in early trading on Monday, driven by the announcement that the company has appointed Liam Mallon, a former executive at ExxonMobil, to its board. The move signals progress in TMC’s deep-seabed mining initiatives and has generated investor optimism about the company’s strategic direction and regulatory outlook.
What Happened
TMC announced the appointment of Liam Mallon to its board as part of its ongoing efforts to advance seabed mining permits. Mallon’s extensive experience in the energy sector, particularly with ExxonMobil, is expected to provide valuable leadership as the company works toward commercializing its seabed mineral extraction projects. The appointment was disclosed in a Form 8-K filing with the SEC, which also noted the election of directors and related compensatory arrangements. The news followed a recent environmental update from the National Oceanic and Atmospheric Administration, which published a notice of intent to prepare an environmental impact statement for TMC’s exploration license application.
What The Data Shows
The stock opened at $3.78, reflecting a 1.0% gap up from the previous close of $3.74. It reached an intraday high of $4.03 at 10:00 AM ET before settling at $4.01. The session saw a volume of 0.8 million shares, which is 0.1 times the 3-month daily average. TMC’s market cap is $1.7 billion, and the stock remains unprofitable with a trailing 12-month EPS of -0.73. The stock has traded between $3.40 and $11.35 over the past 52 weeks. On September 30, the stock printed 10 fresh 52-week highs, indicating a recent surge in momentum.
What To Watch
TMC has no upcoming earnings date scheduled in the near term. Investors should monitor the breadth of coverage and any further developments in the company’s regulatory and permitting process, as well as broader market sentiment toward the materials and mining sector.
