Westlake (WLK) has wrapped up FY 2025 with fourth quarter revenue of US$2.5b and a basic EPS loss of US$4.24, alongside net income excluding extra items of a US$544m loss, setting a cautious tone around profitability. Over recent periods the company has seen quarterly revenue range from US$2.8b to US$3.0b while EPS shifted from a small profit of US$0.05 in Q4 2024 to a series of quarterly losses in 2025. That kind of earnings pressure keeps the focus squarely on margins and how quickly profitability can recover from here.

With the latest numbers on the table, the next step is to see how these results stack up against the widely followed growth and risk narratives around Westlake and where those stories might need updating.

US$1.5b trailing loss puts profit recovery in focus

• On a trailing twelve month basis, Westlake booked a net income loss of US$1.5b on US$11.2b of revenue, which lines up with quarterly losses through FY 2025, including a US$544m loss in Q4 on US$2.5b of revenue.
• Bears point to these losses as evidence that profitability is under pressure, and the bearish narrative assumes profit margins move from about a 13.5% loss today to a 2.3% profit in roughly three years, yet:
  • Trailing EPS swung from a profit of US$4.66 per share at the end of 2024 to a loss of US$11.76 per share by Q4 2025, which is a large shift for the bearish case to reverse.
  • The bearish scenario also looks for earnings to reach US$255.7m by around 2029 from today’s US$1.5b loss, so current losses are exactly the kind of starting point that underpins their caution.

DCF fair value sits above today’s price

• Westlake trades at a P/S of 1.2x on a share price of US$103.09, roughly in line with the US chemicals industry average of 1.2x but above the peer average of 0.7x, while a DCF fair value of about US$131.49 sits well above where the stock is currently priced.
• Supporters of the bullish narrative highlight this gap as a possible sign of upside, and they also lean on earnings forecasts that point to profitability within three years, yet:
  • The DCF framework implies the shares sit roughly 21.6% below that US$131.49 fair value even though the business is loss making on a trailing basis, which is a key tension for anyone focusing on valuation.
  • At the same time, consensus analysts group around a separate price target of US$96.79, which is below the current US$103.09 price, so not all forward looking models line up with the DCF signal.

Bulls and skeptics are looking at the same DCF gap and drawing very different conclusions, so it can help to see how the optimistic camp connects the dots: 🐂 Westlake Bull Case

Modest 3.3% revenue growth vs faster market

• Revenue is forecast to grow at about 3.3% per year, compared with a 10.4% per year benchmark for the broader US market, and over the last year reported trailing revenue eased from US$12.1b to US$11.2b while quarterly sales moved between US$2.5b and just under US$3.0b.
• The consensus narrative leans on longer term demand for housing and infrastructure to support the Housing and Infrastructure Products (HIP) segment, and it expects revenue to reach US$13.0b with margins improving to 6.9%, but:
  • HIP is guided in the commentary to US$4.4b to US$4.6b of revenue at a 19% to 21% EBITDA margin in 2026, which would need to offset softer chemical pricing in the Performance and Essential Materials segment for that margin story to play out.
  • With revenue growth forecasts sitting below the broader market and current losses still large, the balanced view really hinges on HIP providing steadier cash generation while PEM works through global overcapacity and pricing pressure.
