Full withdrawal from polysilicon in Malaysia — booking the impairment and selling the whole stake to OCI (2016)

What settling the bet left behind

At the centre of this decision lay a fork: hold on to a plant that survived impairment, or crystallise the loss and let it go. The confidence of a period when solar demand was swelling and polysilicon was a material with margins above 50% carried the company into the largest overseas investment in its history without preparing for the downside of mass Chinese entry and price collapse. Equipment once brought on line cannot easily be shut down, and losses kept accumulating after the assumptions behind the market had vanished. Repudiating the 2009 design itself and stepping out of the solar-grade market is what gives this withdrawal its weight.

That said, the decade in Malaysia left more than losses. In the shadow of the enormous write-downs, two other seeds — silicon for advanced semiconductors, and dental materials — survived to become the leads of the rebuilding years. Within the same polysilicon, whether to chase scale in commodity grade or to narrow the application at the leading edge was what separated profit from loss, and that fact became the starting point for the portfolio shift that followed the exit. How a process-plant business should hold itself at a distance from commodity markets remains an open question for a company that still carries chemicals and cement.
