Bob Robotti on WLK and the revenge of the old economy

Episode Summary

Executive Summary: The episode argues that Westlake is a classic “revenge of the old economy” and “revenge of the stock picker” story: a U.S.-centered, vertically integrated chemicals/building-products company benefiting from durable North American energy advantages, tight industry supply, and disciplined capital allocation. Bob Rabati emphasizes that Westlake’s returns, free cash flow, and acquisition record suggest earnings are more sustainable than the market implies, making the stock look cheap despite cyclical fears.

Main Topics: Westlake as an old-economy structural winner (Priority: 5/5): Westlake is framed as a chemically intensive, U.S.-based industrial business benefiting from cheap North American natural gas and long-cycle industry consolidation, rather than a typical cyclical commodity producer. Chloralkali economics and pricing power (Priority: 5/5): The core chloralkali business (chlorine and caustic soda) is described as highly consolidated, with limited North American capacity, barriers to entry, and meaningful pricing power as supply discipline has improved. Capital allocation and acquisition-led growth (Priority: 5/5): Westlake’s history of buying underperforming assets, improving operations, and expanding downstream has driven growth in revenues, EBITDA, and free cash flow per share without equity issuance. Why the stock looks cheap (Priority: 5/5): Rabati argues the market is incorrectly treating current earnings as peak cyclical profits, when the business has structurally improved returns on capital and should generate durable cash flow at a low multiple. Vertical integration in housing and infrastructure (Priority: 4/5): Westlake’s move into PVC-based building products is defended as strategically logical because owning more of the supply chain can reduce risk and improve supply reliability in a constrained market. Management quality, family control, and buybacks (Priority: 4/5): The controlling family’s long-term ownership and EVA-based incentives are viewed positively, with the caveat that shareholders must trust management’s capital deployment; buybacks are acknowledged but seen as secondary to acquisitions. Broader regime change in cyclicals and small caps (Priority: 4/5): The discussion widens to argue that many old-economy businesses, especially in chemicals, building products, and materials, are structurally different now and may offer opportunity as capital rotates away from mega-cap growth.

Key Arguments: North American natural gas creates a lasting cost advantage for U.S. chemical and industrial producers versus global competitors. Westlake’s industry has consolidated to a few low-cost producers, enabling stronger pricing discipline and higher profitability. The business has delivered strong long-term growth without issuing stock, indicating real economic compounding rather than financial engineering. The family’s ~70%-plus ownership aligns incentives and reduces the risk of short-term market-driven decisions. Current valuation looks too low because the market is assuming peak earnings, while Rabati believes earnings are sustainable and may improve. Acquisitions have historically been value-creating because Westlake buys distressed or poorly run assets and improves operations, capacity utilization, and employee alignment. Vertical integration into housing and infrastructure can be advantageous post-pandemic because supply chain control matters more than pure outsourcing efficiency. The old economy is being mispriced because investors still anchor on the post-financial-crisis era of low rates and weak inflation, which Rabati sees as an anomaly. Capital allocation should be judged by long-term returns on incremental capital, not by whether buybacks look theoretically better than acquisitions in the abstract. Smaller public companies may become increasingly attractive targets for private capital and activist/special-situational investors as large-cap valuations remain crowded.

Data Points: Revenue growth (10 years): 14% compounded - Westlake’s reported 10-year compounded revenue growth cited on the podcast EBITDA growth (10 years): 24% - Westlake’s long-term EBITDA growth cited as evidence of operating compounding Free cash flow per share growth (10 years): 29% - Used to support the claim that the business has created real per-share value Family ownership: About 70%-75% - Control stake held by the founding family, cited as alignment with shareholders Return on equity (last decade): ~15% - Used to rebut the argument that Westlake is only a low-return cyclical Fully integrated chloralkali plant build cost: 5 years and $5 billion - Investor day figure mentioned to illustrate barriers to new supply Olin EBITDA: From $600 million to over $2 billion - Example of how industry consolidation and pricing power improved profitability in 18 months Time horizon for Dow-DuPont chloralkali contract: Expires in 2025 - Potential inflection point mentioned for chloralkali supply/demand dynamics Builders FirstSource buybacks: $2 billion - Referenced as an example of a related housing-construction beneficiary returning capital aggressively Westlake valuation: ~6x EBITDA / ~6-8x free cash flow - Approximate trading multiple discussed as evidence of cheapness North American integrated chloralkali producers: 3 major low-cost producers - Used to explain pricing discipline and oligopoly-like structure Housing demand: 800,000-1,000,000 homes/year supply fit - Industry capacity has been right-sized to a level below broader U.S. housing need Westlake control ownership in one mention: 75% - Another reference to family control and limited float Westlake acquisition timing: 2018 - AxiAll acquisition highlighted as a key strategic move Thermal/industrial energy advantage duration: Next decade, possibly longer - Rabati’s view on North American hydrocarbon advantage Specialty chemical / commodity cycle backdrop: Post-2008, post-pandemic - Macro framing for the current regime shift in old-economy industries

Pivotal Quotes: "“It’s the revenge of the old economy.”" — Bob Rabati: Central thesis explaining why chemicals, materials, and other industrials may be structurally better than investors assume "“There’s three guys in North America who were the low-cost producer who pretty much control most of the productive capacity.”" — Bob Rabati: Explanation of the chloralkali industry’s tight structure and pricing power "“This is not a business that can’t continue to generate increased returns.”" — Bob Rabati: Rebuttal to the bear case that Westlake is only earning peak cyclical profits

Implications: Listeners should view Westlake and similar old-economy names as potentially mispriced structural compounders, not just cyclical trades. If supply stays tight and capital allocation remains disciplined, these businesses could keep compounding cash flow while the market catches up.
