Is Owens Corning Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) approach here weighs what Owens Corning can generate in cash against the current $117.53 share price.

Analysts feeding into this DCF framework expect Owens Corning’s free cash flow to remain in the hundreds of millions of dollars each year, with projections indicating a growing profile rather than a shrinking one. When those future cash streams are discounted back and compared with today’s $117.53 market price, the model points to an estimated intrinsic value that sits meaningfully above where the stock currently trades.
