Westlake has seen its share price move around in recent years, and that raises a simple question for anyone looking at the stock today. Is the current market value properly reflecting the cash the business is expected to generate over time, or has sentiment drifted away from what its cash flows can reasonably support?
- Over the past 3 years the stock has fallen 37.6%, which puts the focus squarely on whether the current valuation is still anchored to the cash the business can produce.
- The recent expansion of Westlake Pipe & Fittings' PVCO facility in Wichita Falls may support expectations for future cash generation, while also tying up capital that investors will want to see earn a solid return.
- If you'd rather focus on sales, this one's for you. See why Westlake's 0.8x P/S tells a different valuation story.
For investors, the debate is whether Westlake's current share price around US$71, when set against its cash flows and intrinsic value estimate from a Discounted Cash Flow (DCF) approach, can be justified.

Is Westlake Getting Expensive on Cash Flow?
The Discounted Cash Flow (DCF) model here is built on a 2 Stage Free Cash Flow to Equity approach that projects future cash that could accrue to shareholders. Westlake is coming off latest twelve month free cash flow of a loss of $314.9m, so the model leans heavily on the view that cash generation recovers into positive territory over the next decade rather than staying at recent levels.
Analyst and internal projections used in this DCF point to growing annual free cash flows in the coming years, which are then discounted back and compared with today’s share price of $71.17. The recent completion of the large PVCO pipe expansion in Wichita Falls helps explain why the Discounted Cash Flow (DCF) projections put Westlake's estimated intrinsic value substantially below the current share price, because significant capital has already gone into the ground and still needs to translate into stronger cash outcomes.
