Profitability & Margins

AI Review

The company has reached a major milestone by turning its gross margins positive, reaching around 11% to 20% recently, compared to deeply negative numbers in previous years. This means they can now make each battery cell for less than it costs to sell, thanks to high prices paid by military customers. However, overall profit margins remain negative because of high research and administrative expenses. There is a strong clash over the future of these margins. Optimists expect margins to keep expanding as production scales up and costs drop. Skeptics argue that relying on outside factories will squeeze margins, and any supply chain disruptions or rising material costs will quickly wipe out these recent gains, returning the company to a loss.
