China National Building Material (SEHK:3323) Faces A Big Fair Value Gap As Losses Land

China National Building Material (SEHK:3323) reported a net loss of CNY 728.3 million for the nine months to September 30, 2026, on sales of CNY 129.99b, following today’s earnings announcement.

China National Building Material's latest earnings setback lands on a weak price chart, with the share price falling about 44% year to date and the 1 year total shareholder return declining roughly 47%. This signals fading momentum as investors reassess the higher perceived risk around the shift to a loss.

Capitalize on the pressure China National Building Material is under by reviewing hand picked building and materials peers with stronger balance sheets and cash flows in our list of solid balance sheet and fundamentals (206 results).

After a slide like this, China National Building Material either offers meaningful upside from a beaten down base, or most of the easy rebound has already played out. The valuation section examines which scenario this currently appears closer to.

Preferred Multiple of 0.1x P/S: Is it justified?

China National Building Material last closed at HK$2.90, and on a P/S ratio of 0.1x the shares are pricing in far lower sales value than both peers and internal estimates suggest. For investors tracking valuation resets after big drawdowns, that gap on revenue multiples is the core question.

The price to sales ratio compares the company’s market value to its annual revenue. For a diversified building materials group like China National Building Material, with cement, new materials and engineering services all contributing, sales based metrics are often used when earnings are distorted by losses or heavy investment.

On this measure the stock is trading at what looks like a deep discount. Management is currently unprofitable and interest payments are not well covered. Yet the P/S ratio of 0.1x is far below the Asian Basic Materials industry average of 1x and the peer average of 7.5x. Our fair price to sales ratio estimate is 0.5x, a level the market could move towards if sentiment around profitability and balance sheet risk improves.

Result: Price-to-Sales of 0.1x (UNDERVALUED)

Still, the ongoing net loss and weak interest coverage mean any setback in funding conditions or construction demand could quickly undercut the China National Building Material rebound story.
