What happened

Lithium prices fell sharply in October. The most-traded lithium carbonate futures contract in China fell 11.8% in a single day on 12 October, to about US$15,640 per tonne — its lowest level since December 2025 and roughly half its peak on 13 May, amid growing worries about demand in 2027 [1]. Albemarle (NYSE: ALB), which produces lithium from brine at Chile’s Salar de Atacama, reports third-quarter results on 4 November [2]. Its main project in Chile is a US$3.1bn plan to add direct lithium extraction (DLE) to its existing operations, which is now under Chile’s environmental review [3]. The obvious question is whether lower prices make that spending harder to justify.

What people are missing

The answer depends on how much lithium the current process loses. Albemarle pumps brine into evaporation ponds and lets the sun remove the water, and the route from pumping to finished product can take up to 24 months [4]. As the water evaporates, other salts crystallise out and are removed, while the lithium concentration increases from about 0.2% to 6% [5]. Solar evaporation recovers less than half of the lithium in the brine [4], so more than half of the lithium Albemarle pumps never reaches the customer. DLE works differently. The brine passes over a solid material, such as a manganese, titanium or aluminium oxide, that picks up lithium ions and leaves most of the other dissolved salts behind [4]. Albemarle’s pilot plant recovered more than 94% of the lithium [6].

Why it matters

Albemarle currently takes a net 442 litres of brine per second out of the salt flat (the amount pumped out minus the amount put back), and the DLE plan does not require an increase in the permitted extraction volume [3][6]. So the way to grow in Chile is to get more lithium out of the same brine. With the first DLE line, Albemarle expects to recover nearly twice as much lithium while cutting net pumping to 342 litres per second, and to as little as 142 with all six lines [3]. Getting more lithium from less pumping means each tonne costs less to produce. When prices fall, the producers with the lowest costs are the ones that keep making money, so lower prices make the case for DLE stronger, as long as Albemarle can afford to build it.

What we are watching next

At the results on 4 November [2], we are watching for any change to the DLE timeline. Albemarle has already cut its 2026 capital spending plan to about US$500m, down 15% on 2025 [7], and plans to start with one production line while it proves the technology at commercial scale [8]. A further delay would suggest that lower prices are slowing the project down.

What happened

Heidelberg Materials has agreed to buy NCC’s aggregates and asphalt businesses in Sweden and Norway for about SEK 5.5bn [1]. It is Heidelberg’s part of NCC’s SEK 8.2bn sale of its Industry division, with CRH buying the Danish and Finnish operations [2]. The deal includes 106 aggregates sites and 44 hot-mix asphalt plants. Heidelberg says the acquisition strengthens its exposure to infrastructure spending — the obvious reading is that the company wants more capacity. The more important point is where the new capacity sits.

What people are missing

Aggregates are heavy and relatively cheap, so transport quickly becomes a major part of the delivered cost. A quarry close to a road project has a clear advantage over one much farther away, even if both produce the same material at the same factory cost. UK competition authorities have often treated aggregates as local markets, with around 30 miles used as a typical starting point for a quarry’s catchment area [3]. The quarries also come with permits, which are slow to get — Heidelberg knows this from its own limestone quarry at Slite on Gotland, where a long-term permit was refused in 2021 and a 30-year licence only came through in 2025 [4].

Asphalt is even more local. Hot-mix asphalt has to be compacted before it cools to about 80°C [5], and it cools faster in cold air and wind [6], so the distance a plant can serve shrinks in a Nordic spring or autumn. European Commission merger analysis has treated asphalt markets as highly local, with around 40km used as a service radius in some cases [7]. That means Heidelberg is buying 150 extra production points, not simply more tonnes of output. A denser network should cut delivery distances and put more infrastructure projects within reach of a Heidelberg site.

Why it matters

If Heidelberg has a site 15km from a project while a rival is 70km away, the rival starts with a transport-cost disadvantage. So Heidelberg is not only betting on stronger Nordic infrastructure demand — it is making sure more of that demand sits close to one of its own sites. The main risk is warm-mix asphalt, which can be compacted at lower temperatures [6]. If it becomes standard, asphalt plants could serve a wider area and the advantage of being close would shrink.

What we are watching next

Regulatory approval comes next, and NCC expects the deal to complete in the second half of 2027 [2]. Regulators are likely to focus on areas where Heidelberg and NCC sites serve the same catchment. Any forced quarry or asphalt-plant sales would support the idea that location is the key source of value in the deal.
