For next year, the company is targeting revenues to jump by 50 to 100 percent to be driven by the full effect of newly launched post-quantum chips, completion of its consolidation with IC’ALPS, and higher revenues from Quantix Edge.

9. Lithium Americas Corp. (NYSE:LAC)

Lithium Americas surged by 18.78 percent week-on-week, as investors positioned portfolios amid the surging prices of lithium.

Latest data from Trading Economics showed that prices of lithium jumped by 18.45 percent in November, and by 0.48 percent to $93,750 on Friday alone.

The overall optimism spilled over Lithium Americas Corp. (NYSE:LAC), owner of the Thacker Pass mine—one of the largest lithium resources in the US—supported by the US government’s earlier backing in the company following the acquisition of a 5 percent stake and another 5 percent in the Thacker Pass mine.

Just recently, Lithium Americas Corp. (NYSE:LAC) announced the results of its earnings performance in the third quarter of the year, where it widened its net loss by 2,243 percent to $199.16 million from only $8.5 million in the same period last year, dragged by higher losses on financial instruments measured at fair value.

Operating expenses also jumped by 58 percent to $9.7 million from $6.15 million year-on-year, amid higher exploration expenditures.

Despite the dismal results, Lithium Americas Corp. (NYSE:LAC) remained upbeat about its business, saying that it was “full steam ahead on construction” for the Thacker Pass mine project.

“Our workforce continues to grow each week, with approximately 700 workers now on-site and over 80% of detailed engineering complete. We’re making tangible progress across all fronts—from steel and concrete work to site infrastructure and the expansion of our Workforce Hub,” said Lithium Americas Corp. (NYSE:LAC) President and CEO Jonathan Evans.
