Breaking Down Westlake Corporation (WLK) Financial Health: Key Insights for Investors

You're looking at Westlake Corporation's stock chart and scratching your head, right? The consensus from analysts is still a 'Buy,' but the latest earnings report shows a massive GAAP net loss of $782 million for the third quarter of 2025, which translates to a diluted loss of ($6.06) per share, largely due to a non-cash goodwill impairment. That's a jarring headline, but as a seasoned analyst, I can tell you that the true financial health is defintely more nuanced than that single number suggests; the company is still on track for an annual revenue of around $11.48 billion, and they're making smart, proactive moves. They just completed a near-$1.2 billion debt refinancing to push out near-term obligations, and they've targeted $200 million in structural cost reductions for 2026 to combat the global oversupply hitting their Performance and Essential Materials segment. We need to look past the impairment charge to see the real operational risks and the clear opportunities in their Housing and Infrastructure Products segment.

Revenue Analysis

You need to know where Westlake Corporation (WLK)'s money comes from, especially in a challenging year like 2025, to map out your investment risk. The direct takeaway is this: Westlake's revenue is on track to hit about $11.48 billion for the full 2025 fiscal year, but it's a story of two segments, with the chemical side facing significant headwinds.

To be fair, the company's diversified model is what keeps the lights on. Westlake Corporation's revenue streams break down into two main segments: Performance and Essential Materials (PEM) and Housing and Infrastructure Products (HIP). The PEM segment, which includes commodity chemicals like PVC resin and chlorine, is defintely the larger contributor, but it's also the current pain point.

Here's the quick math on the expected contribution for the full 2025 fiscal year, based on the total projected revenue of $11.48 billion and management's outlook for the HIP segment:

• Performance and Essential Materials (PEM): Expected to contribute roughly $7.08 billion, or about 61.7% of total revenue.
• Housing and Infrastructure Products (HIP): Expected to contribute at the low end of the guidance range, around $4.4 billion, or about 38.3% of total revenue.

The HIP segment, which sells products like siding, roofing, and pipe, is the more stable player, with its full-year 2025 revenue expected to land between $4.4 billion and $4.6 billion. That's a solid, predictable base.

When we look at the year-over-year revenue growth rate, the picture is one of contraction. The trailing twelve months (TTM) revenue for Westlake Corporation ending September 30, 2025, was $11.48 billion, which represents a decline of about 5.32% compared to the prior year's TTM revenue. That's a clear signal of the weak global industrial demand impacting the business.

The significant change in revenue streams is not a structural shift in product mix, but a dramatic difference in segment performance. The PEM segment is seeing lower average sales prices and margin compression due to weak global industrial demand, particularly for chlorovinyls. For example, in the first quarter of 2025 alone, the PEM segment reported net sales of $1.850 billion, but also a loss from operations of $163 million. Meanwhile, the HIP segment, while facing its own sequential sales volume decline in the third quarter, has shown more resilience against the macroeconomic tide.

To see how these segments stack up quarter-by-quarter in 2025, look at the net sales data:

What this estimate hides is the potential for a quicker rebound in the PEM segment if global industrial activity picks up, but for now, the chemical side is the drag on overall revenue growth.

Profitability Metrics

You need to know if Westlake Corporation (WLK)'s recent profit dip is a structural problem or a cyclical low. The Q3 2025 results show profitability has been severely compressed by a major one-time charge, but even the adjusted figures point to significant underlying margin pressure from lower pricing power and demand.

Here's the quick math on the third quarter of 2025 (Q3 2025) performance: Westlake Corporation reported an unadjusted net loss of $782 million on net sales of $2.838 billion, resulting in a negative net profit margin of -27.55%. That's a stark swing from the net income of $108 million reported in Q3 2024. This is defintely a challenging environment.

The primary driver of this unadjusted loss was a $727 million non-cash goodwill impairment charge in the Performance and Essential Materials (PEM) segment (the chemical side of the business). Excluding this and other identified items, the adjusted net loss was a more modest $38 million, which translates to an adjusted net profit margin of -1.34% for Q3 2025.

• Gross Profit Margin: 8.32% in Q3 2025, showing a slight sequential improvement from Q1 2025's 8%.
• Operating Profit Margin: -27.06% (Unadjusted loss from operations of $766 million).
• Net Profit Margin: -27.55% (Unadjusted net loss of $782 million).

What this estimate hides is the true cyclical pressure on the core business. Net sales fell to $2.838 billion in Q3 2025 from $3.117 billion in Q3 2024, a clear sign of lower average sales prices and reduced demand, especially in the PEM segment.

Industry Comparison and Operational Efficiency

When we look at the industry averages for 2025, Westlake Corporation's margins are clearly underperforming. The company operates in two main areas: chemicals (PEM) and building products (HIP). For context, the average gross profit margin for the Basic Chemical industry is around 13.75%, and for Building Materials, it's about 30.94%.

Westlake Corporation's consolidated Q3 2025 Gross Profit Margin of 8.32% is significantly below both benchmarks. This gap highlights the intense pressure on product pricing and the high cost of goods sold (COGS), which is a major red flag for operational efficiency right now. The PEM segment is particularly exposed to global commodity price swings, which are eating into its margins.

Here is a quick comparison of Westlake Corporation's Q3 2025 performance against the industry averages:

The Housing and Infrastructure Products (HIP) segment, which is tied to construction, showed some resilience but still saw its operating income drop to $151 million in Q3 2025, a $71 million decrease sequentially. The good news is that management is taking clear action on costs. They have identified $200 million in cost savings expected to be achieved in 2026, plus another $100 million in annual loss removal from footprint optimization actions like the Pernis Shutdown. This focus on cost management and asset rationalization is the right move to help restore margins closer to historical and industry norms in the near-term.

Debt vs. Equity Structure

You're looking at Westlake Corporation (WLK) to understand how they finance their operations, which is smart because capital structure tells you everything about a company's risk tolerance. The direct takeaway is that Westlake Corporation maintains a conservative, equity-heavy balance sheet relative to its peers, but recent debt activity points to a strategic shift toward funding growth and managing near-term maturities.

As of the third quarter of 2025, Westlake Corporation's debt profile is manageable, sitting at a total of approximately $4.656 billion. This is broken down into a net long-term debt of $3.906 billion and a current portion of long-term debt (short-term debt) of $750 million. This low short-term debt component suggests minimal immediate refinancing pressure, which is defintely a good sign in a volatile interest rate environment.

The company's debt-to-equity (D/E) ratio is the clearest indicator of this conservative approach. With total stockholders' equity at $9.426 billion as of September 30, 2025, the calculated Debt-to-Equity ratio stands at roughly 0.49. Here's the quick math: Total Debt ($4.656B) divided by Total Equity ($9.426B). This is a low leverage position.

• Westlake Corporation's D/E ratio of 0.49 is significantly below the US Chemicals industry average of 0.85.
• This low ratio indicates Westlake Corporation relies more on shareholder capital than debt to fund assets, translating to lower financial risk.

Still, the company is actively managing its debt maturity schedule. In November 2025, Westlake Corporation priced a $1.2 billion senior unsecured notes offering. This new debt is strategically staggered, with $600 million due in 2035 at a 5.550% rate and another $600 million due in 2055 at a 6.375% rate. The primary use of proceeds is to refinance the outstanding 3.600% Senior Notes due 2026, plus fund the pending acquisition of the ACI/Perplastic Group's global compounding solutions business.

This is how Westlake Corporation balances the two: they use debt strategically for large, accretive acquisitions and forward-looking refinancing, but their long-term bias is toward deleveraging. S&P Global Ratings affirmed Westlake Corporation's issuer credit rating at 'BBB+' in November 2025, but the outlook remains Negative. This negative outlook isn't a surprise; it reflects the expectation that their funds from operations (FFO) to debt will remain below 45% over the next few quarters due to weaker margins in their Performance and Essential Materials (PEM) segment, even as they take cost-cutting measures.

What this estimate hides is Westlake Corporation's proven track record of using its strong free cash flow to repay debt after major acquisitions, which is a key part of their capital allocation philosophy. They have a history of prioritizing debt repayment over excessive financial leverage.

Liquidity and Solvency

You need to know if Westlake Corporation (WLK) can cover its short-term bills, especially with the recent operational headwinds. The good news is the company maintains a strong liquidity cushion, but the cash flow trends show a clear strain from capital spending that you need to watch defintely.

Assessing Westlake Corporation (WLK)'s Liquidity Positions

Westlake Corporation's short-term financial health, measured by its current and quick ratios, is robust. The current ratio sits at a healthy 2.47, meaning the company has $2.47 in current assets for every dollar of current liabilities. This is a strong buffer, well above the typical 1.0 benchmark for safety.

The quick ratio (acid-test ratio), which strips out inventory-often the least liquid current asset-is also strong at 1.75. This tells me Westlake Corporation can cover its immediate obligations even if it sold zero inventory. This is a sign of excellent short-term solvency. You don't see this level of immediate coverage in many capital-intensive industries.

Working Capital and Cash Flow Trends

While the ratios look great, the underlying working capital trend for the trailing twelve months (TTM) ending September 2025 shows a negative shift of $-441 million. This negative change in working capital means that over the last year, the growth in current assets (like inventory or receivables) was outpaced by the growth in current liabilities, or simply that cash was tied up in the operating cycle. Here's the quick math on the recent cash flow picture (in millions):

Net cash provided by operating activities (OCF) was $182 million in Q3 2025, which is an improvement from the $135 million in Q2 2025. But, capital expenditures (CapEx), a major component of investing cash flow, were $239 million in Q3 2025. This means the company had negative free cash flow in Q3, and also in Q1 2025, which was $(325) million. The business is spending more on maintaining and expanding assets than it generates from operations right now.

Liquidity Strengths and Near-Term Actions

The primary strength is the sheer size of the cash hoard. As of September 30, 2025, Westlake Corporation held $2.1 billion in cash, cash equivalents, and fixed-income investments. This is a massive war chest that fully mitigates the negative free cash flow we've seen this year. Total debt remains at $4.7 billion, but the company's high cash balance and strong ratios mean debt servicing is not a near-term concern.

• Maintain a cash balance over $2 billion.
• Cover short-term debts 1.75x without selling inventory.
• Fund CapEx from the balance sheet, not just operations.

The near-term risk is that the negative free cash flow persists, which forces the company to draw down its cash balance to fund capital projects and dividends. Management is addressing this by targeting cost reductions, which should improve profitability and, eventually, operating cash flow. You can review the strategic rationale for these moves in the Mission Statement, Vision, & Core Values of Westlake Corporation (WLK).

Valuation Analysis

You're looking at Westlake Corporation (WLK) after a significant price drop, wondering if it's a value trap or a genuine buying opportunity. The direct takeaway is that Westlake Corporation is currently trading at a discount based on book value and analyst price targets, suggesting it is undervalued right now, but the negative earnings point to serious near-term profitability risks you can't ignore.

The stock's performance over the last 12 months (52 weeks) has been brutal, with the price falling by over 53.85% as of November 2025. The price has ranged from a high of $133.51 to a recent low of $56.33, with the stock trading around $59.03 near the end of November 2025. This steep decline reflects the challenging macroeconomic environment, particularly the pressure on sales prices and margins in the Performance and Essential Materials (PEM) segment.

Here's the quick math on the key valuation multiples, using data primarily from the trailing twelve months (TTM) ended September 2025:

• Price-to-Book (P/B) Ratio: At 0.80, the stock is trading below its book value. This is a classic indicator of potential undervaluation, suggesting the market values the company's assets at less than their accounting value.
• Price-to-Earnings (P/E) Ratio: The TTM P/E is effectively non-existent or negative, reported around -111.64, because the company posted a net loss in the TTM period ended September 2025, with an Earnings Per Share (EPS) of -$7.410. When a company loses money, the P/E ratio is not a useful valuation tool. However, the forward P/E, based on next year's earnings forecasts, is cited as a high 99.66, which signals that investors are paying a premium for the expected recovery in earnings.
• Enterprise Value-to-EBITDA (EV/EBITDA) Ratio: This multiple, which strips out capital structure differences, is around 9.5x for the latest twelve months. To be fair, this is significantly below the industry median of approximately 13.995, which suggests the company is currently cheaper than its peers on an operating basis.

The dividend picture is interesting, but also a bit of a red flag. Westlake Corporation pays an annual dividend of $2.12 per share, giving a current dividend yield of about 3.6%. Still, the payout ratio is reported as -28.57% because the company has negative earnings. This means the dividend is currently being paid out of cash reserves or debt, not current profit, which is defintely not sustainable long-term without an earnings turnaround. They have a 19-year history of dividend increases, though, which shows a commitment to shareholder returns.

The consensus among the sixteen Wall Street analysts covering Westlake Corporation is a Moderate Buy. The average twelve-month price target is $87.53, ranging from a low of $75.00 to a high of $103.00. This average target implies a significant upside from the current price, reinforcing the idea that the stock is undervalued based on future expectations. You can read more about the company's fundamentals in our full analysis: Breaking Down Westlake Corporation (WLK) Financial Health: Key Insights for Investors.

So, the technical and book value metrics scream 'buy,' but the negative earnings and P/E ratio are a stark warning. The market is pricing in a major cyclical recovery, but until that forecasted EPS of $1.69 for next year materializes, this is a speculative value play.

Risk Factors

You need a clear-eyed view of Westlake Corporation's (WLK) risk landscape, and the core takeaway is this: their diversification is a crucial buffer, but the cyclical chemical business-Performance and Essential Materials (PEM)-is currently a significant drag on the entire enterprise. The near-term challenge is less about solvency and more about margin compression and operational execution as they restructure.

Here's the quick math on the pressure points: PEM's loss from operations was substantial, hitting $163 million in Q1 2025, followed by a $188 million loss in Q2 2025, and another $158 million in Q3 2025. This segment's struggles, driven by global oversupply and high feedstock costs, are what prompted the company's aggressive response.

External and Industry Headwinds

The external risks are largely macroeconomic and industry-specific. The chemical sector is struggling with global supply-demand imbalances, especially in chlorovinyls and polyethylene. Plus, rising costs for natural gas and other feedstocks continue to pressure margins; you can't control the price of raw materials, so the profit margin (the spread) shrinks. We also see softening demand in North American residential construction, which is the primary market for their more stable Housing and Infrastructure Products (HIP) segment. HIP is resilient, still projected to deliver EBITDA of about $900 million in 2025, but a housing slowdown is defintely a headwind.

• Global oversupply in chemicals keeps prices low.
• High feedstock and energy costs squeeze PEM margins.
• Tariff-related uncertainties disrupt global trade flows.

Operational and Financial Risks

The biggest financial risk highlighted in the 2025 filings is the non-cash goodwill impairment charge of $727 million recorded in Q3, which fully impaired the goodwill associated with the North American chlorovinyls business. This is an accounting measure, but it signals that the long-term cash flow forecasts for that business unit have been significantly reduced. Operational risks have also been costly, with approximately $200 million in costs incurred so far in 2025 from a combination of planned turnarounds (like the Petro-1 ethylene cracker) and unplanned outages. You can't make product if the plant is down.

Another key financial metric to watch is the company's credit profile. S&P Global Ratings revised the outlook to negative, projecting that Westlake Corporation's Funds From Operations (FFO) to debt ratio will remain below 45% for the next few quarters. This is a critical liquidity measure that reflects the weaker earnings in the PEM segment.

Mitigation and Strategic Actions

Westlake Corporation is not sitting still; they are executing a clear strategy to combat these pressures. The primary lever is cost reduction. Management has raised its 2025 company-wide cost reduction target to a range of $150 million to $175 million, with an eye toward achieving $200 million by 2026. They are also optimizing their global footprint, which includes the permanent closure of the Pernis, Netherlands epoxy facility, a move expected to save about $100 million annually.

The company also reduced its 2025 capital spending (CapEx) by 10% to $900 million, a clear signal of financial discipline in a tough market. This is a necessary move to protect cash flow while the PEM segment recovers. The resilience of the HIP segment, which is forecast to deliver 2025 revenue of $4.2 billion to $4.4 billion with an EBITDA margin of 20%-22%, provides the financial stability to execute this turnaround.

Growth Opportunities

You're looking past the current cyclical trough in the chemical sector, and you're right to focus on where Westlake Corporation (WLK) is building its future. The direct takeaway is that while the Performance and Essential Materials (PEM) segment is struggling now-evidenced by the $727 million non-cash impairment charge in Q3 2025-the company's strategic growth is firmly anchored in its Housing and Infrastructure Products (HIP) segment and aggressive cost-cutting.

The core growth drivers are clear and actionable, focusing on diversification and operational efficiency. Here's the quick math: Westlake Corporation is on track to achieve between $150 million and $175 million in structural cost reductions in 2025, plus they are planning for an additional $200 million by 2026, with about 75% of that benefiting the PEM segment. That's a serious move to improve margins. The company is defintely positioning for the next up-cycle.

The HIP segment is the rock right now, with revenue projected to be in the range of $4.2 billion to $4.4 billion for the full year 2025, and an EBITDA margin expected between 20% and 22%. This resilience stems from a few key areas:

• Infrastructure Spending: A significant portion of the North American pipe infrastructure-about 33% of all installed pipe-is over 50 years old, creating a massive, non-cyclical demand for replacement and new construction.
• Product Innovation: Innovations like their PVCO pipe, an advanced molecular-oriented PVC product, use 40% less PVC while delivering superior performance, directly addressing customer needs for efficiency and sustainability.
• Market Expansion: The acquisition of ACI is a strategic move to expand the product offering and market reach of the global compounds business, which is a high-margin area.

Analysts are projecting a challenging fiscal year 2025 with a consensus Earnings Per Share (EPS) forecast of -$1.04, reflecting the current market headwinds and the Q3 net loss of $38 million (excluding the impairment). But, the forward-looking estimates show a strong rebound, with EPS expected to grow to $1.87 in 2026. This is a classic cyclical play. Furthermore, revenue is forecast to grow at an average of 4.6% annually over the next three years, outpacing the broader U.S. Chemicals industry forecast of 4.1%.

Westlake Corporation's competitive advantage is its integrated business model, which provides a streamlined supply chain from raw materials to finished building products, offering a cost and pricing edge. Plus, they maintain a strong balance sheet with $2.1 billion in cash and investments as of September 30, 2025, giving them flexibility for strategic investments like the new PVCO pipe facility in North Texas. They are also making a clear strategic pivot toward sustainability, including a deal to generate around 160,000 megawatt-hours of solar energy annually.

Here's a snapshot of the forward-looking financial trajectory and key drivers:

What this estimate hides is the potential for a faster-than-expected recovery in the PEM segment, which would significantly boost those 2026 earnings estimates. To be fair, the global supply-demand imbalance in the chlorovinyl chain is still a risk.
