Westlake Corporation (WLK) is a diversified global manufacturer and marketer of performance and essential materials, as well as housing and infrastructure products. With a storied history spanning over three decades, Westlake has evolved into a vertically integrated titan, commanding leading positions across its key business segments.

Business Overview

Westlake's origins trace back to 1986, when the Chao family founded the company. Brothers James Y. Chao and Albert Y. Chao, along with their father T.T. Chao, played pivotal roles in establishing Westlake. Since its inception, the company has pursued a disciplined growth strategy focused on plant acquisitions, new plant construction, and internal capacity expansions.

The company's evolution has been marked by numerous strategic acquisitions and expansions. In 2014, Westlake formed Westlake Chemical Partners LP to operate, acquire, and develop ethylene production facilities and related assets. A significant milestone was reached in 2019 when Westlake acquired an additional 34.8% of the membership interests in LACC, LLC, a joint venture with Lotte Chemical USA Corporation, increasing its ownership to 50%. This venture was established to build and operate an ethylene facility, further strengthening Westlake's position in the market.

Westlake's growth trajectory continued with key acquisitions in 2021, including the purchase of the global epoxy business of Hexion Inc. and the acquisition of LASCO Fittings, Inc. and DX Acquisition Corp. (Dimex). These strategic moves have significantly expanded Westlake's product portfolio and market reach.

The company operates in two principal segments: Performance and Essential Materials (PEM) and Housing and Infrastructure Products (HIP). The PEM segment encompasses Westlake's production and marketing of a wide array of petrochemicals, including polyethylene, styrene monomer, chlor-alkali chemicals, and epoxy resins. These products serve as critical inputs for a diverse range of industries, from packaging and coatings to renewable energy and healthcare. Westlake's extensive downstream integration and advantaged feedstock position enable the company to maintain a competitive edge in this cyclical landscape.

On the other hand, the HIP segment leverages Westlake's vertically integrated capabilities to manufacture and market a comprehensive portfolio of building products, such as vinyl siding, trim, mouldings, stone veneer, roofing, and PVC pipes and fittings. This business benefits from Westlake's strong brand recognition and reputation for quality, serving both residential and infrastructure markets across North America.

Throughout its history, Westlake has faced various challenges, including the cyclical nature of the petrochemical industry and volatility in raw material prices and energy costs. To mitigate these challenges, the company has implemented a vertical integration strategy and focused on operational efficiency. For instance, Westlake's ethylene production capabilities provide a cost advantage by enabling the company to use ethane feedstock rather than more expensive naphtha.

Financials and Operations

Financials

Over the past five years, Westlake has delivered consistent financial performance, underscoring the strength of its diversified business model. In 2024, the company reported net sales of $12.14 billion and net income of $602 million, or $4.64 per diluted share. The company's financial position remains robust, with $2.92 billion in cash and cash equivalents and a net debt to EBITDA ratio of 0.7x as of December 31, 2024.

Westlake's operational excellence is exemplified by the record-breaking performance of its HIP segment, which achieved income from operations of $807 million and an EBITDA margin of 24% in 2024. This marks the fifth consecutive year of record earnings for the HIP business, demonstrating the division's ability to capitalize on strong demand for housing and infrastructure products in North America.

While the PEM segment faced some headwinds in 2024 due to weaker global demand and margin compression, Westlake has taken proactive steps to mitigate these challenges. The company implemented $170 million in cost-saving initiatives during the year, exceeding its initial target of $125-$150 million. Additionally, Westlake has strategically reduced the footprint of its European epoxy business, realigning the asset base to improve long-term competitiveness.

In the most recent quarter (Q4 2024), Westlake reported revenue of $2.84 billion, representing a modest year-over-year growth of 0.6%. Net income for the quarter was $7 million, with operating cash flow of $434 million and free cash flow of $149 million. The company noted that Q4 2024 results were impacted by lower sales prices for PVC resin, epoxy resin, caustic soda, and chlorine, partially offset by higher sales volumes. Additionally, the company accrued $75 million in expenses related to the decision to mothball two units within the European Epoxy business.

Liquidity

Westlake's liquidity position remains strong, as evidenced by its substantial cash reserves and low leverage ratio. The company's prudent financial management has enabled it to maintain flexibility in its capital allocation strategy, allowing for continued investment in growth initiatives and shareholder returns.

As of December 31, 2024, Westlake had a debt-to-equity ratio of 0.0006, a current ratio of 2.8, and a quick ratio of 2.04. The company has a $1.5 billion revolving credit facility, of which no amounts were drawn as of the end of 2024, further enhancing its financial flexibility.

Looking ahead, Westlake expects the HIP segment to maintain its momentum, forecasting revenue between $4.4-$4.6 billion and an EBITDA margin of 20-22% for 2025. The company also anticipates continued demand growth in its PEM end markets, such as packaging, coatings, and construction, and plans to drive further efficiencies through its cost-reduction efforts.

For 2025, Westlake has provided the following guidance:

• Total capital expenditure spend is expected to be similar to its depreciation run rate, including costs for a planned turnaround at its PetroOne ethylene unit.
• The effective tax rate is projected to be approximately 23% for the full year.
• Cash interest expense is anticipated to be approximately $160 million.
• The company aims to deliver $125 million to $150 million in cost reductions.

Segment Overview

Performance and Essential Materials (PEM)

The PEM segment includes a diverse portfolio of products that are fundamental to many industries. This segment comprises Westlake North American Vinyls, Westlake North American Chlor-alkali Derivatives, Westlake European Asian Chlorovinyls, Westlake Olefins, Westlake Polyethylene, and Westlake Epoxy.

Westlake is a leading global producer of chlor-alkali products, with the capacity to produce approximately 7.4 billion pounds of chlorine and 8.1 billion pounds of caustic soda annually. These products are used both internally and sold to external customers.

The company is also a major producer of PVC, with the capacity to produce approximately 6.8 billion pounds of commodity PVC and 1.0 billion pounds of specialty PVC per year. Westlake's polyethylene business has the capacity to produce 1.5 billion pounds of low-density polyethylene (LDPE) and 1.1 billion pounds of linear low-density polyethylene (LLDPE) annually.

The recently acquired Westlake Epoxy business is a leading global producer of epoxy specialty resins, modifiers, and curing agents, with a total capacity of 580 million pounds per year.

Housing and Infrastructure Products (HIP)

The HIP segment includes Westlake's building products, pipes and fittings, and PVC compounds businesses. This segment manufactures and markets products such as residential siding, trim and moldings, stone, roofing, windows, outdoor living products, PVC pipe and fittings, and custom PVC compounds.

In 2024, the HIP segment reported net sales of $4.32 billion, up from $4.21 billion in 2023, driven by higher sales volumes for pipe and fittings and siding and trim products. Income from operations for this segment increased to $807 million in 2024, up from $710 million in 2023, primarily due to higher sales volumes and lower raw material and energy costs, partially offset by lower product pricing.

Risks and Challenges

As a global manufacturer, Westlake is exposed to various risks, including macroeconomic volatility, supply chain disruptions, and environmental regulations. The cyclical nature of the petrochemical industry can also introduce earnings volatility, as evidenced by the recent margin compression in the PEM segment.

Furthermore, Westlake faces competitive pressures across its business lines, as the company competes with large, multinational players as well as regional producers. The company's ability to maintain its competitive edge will be crucial in navigating these challenges.

Geopolitical tensions, trade policies, and changing consumer preferences also pose potential risks to Westlake's operations and financial performance. The company's diverse geographic footprint and product portfolio help mitigate these risks to some extent, but the company remains vigilant in monitoring and addressing these evolving factors.

The housing market started softening in the second half of 2022 due to factors like rising mortgage rates, elevated construction costs, and tariffs. However, Westlake expects the Infrastructure Investment and Jobs Act to have a favorable long-term impact on the Housing & Infrastructure Products segment.

Conclusion

Westlake Corporation's diversified business model, vertically integrated operations, and proven track record of operational excellence have positioned the company as a formidable player in the global chemicals and building products industries. While the company faces various cyclical and structural challenges, Westlake's strategic initiatives, cost-saving efforts, and focus on sustainable innovation suggest that the company is well-equipped to navigate the volatile market environment and continue delivering value to its shareholders.

The company's strong performance in the HIP segment, coupled with its proactive measures to address challenges in the PEM segment, demonstrates Westlake's resilience and adaptability. As Westlake continues to optimize its operations and capitalize on growth opportunities, particularly in North America where demand has remained relatively strong, the company is poised to maintain its competitive position in the industry.
