TMC Unit Economics — The Boring Math Behind the Weird Idea


Coffee shop, two stools. A napkin and a pen.

You: “Okay, one napkin. Think one truckload = one wet tonne of nodules.”

Friend: “What’s a tonne worth?”

You (scribbling): “Basket of Ni/Cu/Co/Mn ≈ $400/tonne at today-ish prices.”

Friend: “And it costs?”

You: “To lift, ship, process, monitor, run the team—call it $280/tonne.”

Friend: “So profit?”

You (circling):$400 − $280 ≈ $120/tonne cash. That’s our EBITDA per tonne.”

Friend: “How much do they move?”

You: “One system = ~1.3 million tonnes/year1.3M × $120 ≈ $156M EBITDA.”

Friend: “What’s that in stock price?”

You (new line): “Put a boring 10× on $156M → $1.56B EV.

Subtract ~$0.4B debt$1.16B equity.

Divide by ~406M shares~$2.85/share for one system.”

Friend: “And two systems?”

You: “Just double the tonnes: ~$312M EBITDA → about $5–6/share on the same $120/tonne.”

Friend: “What if margins are better?”
