LYB — LyondellBasell

TL;DR

LyondellBasell is a global polyolefins and refining company — the largest producer of polypropylene compounds globally and a major PE producer. The Iran conflict is the single biggest earnings windfall for LYB among the three petchem names: FY26 EBITDA nearly doubles vs. prior estimates. BofA nonetheless rates the stock Underperform at 68 PO — the conflict tailwind is temporary, ~1 year of overearning appears priced in, and the post-conflict base case is a return to global oversupply.1

Business

LyondellBasell operates across Olefins & Polyolefins (Americas and Europe/Asia), Intermediates & Derivatives (propylene oxide, oxyfuels), Refining, and a growing Technology licensing segment. LYB is highly leveraged to PE and PP price-cost spreads, with feedstock costs varying by region (NGL in North America, naphtha in Europe). The company generates strong free cash flow at cycle peaks and has a history of aggressive buybacks and dividends.1

Thesis

  • Biggest near-term beneficiary, but also the most cyclically exposed. BofA’s FY26 EBITDA estimate of 2,546mn — the largest percentage uplift of the three names. The same leverage works in reverse when prices normalize.1
  • ~1 year of overearning priced into current shares. At 68 PO, BofA calculates excess market cap / excess EBITDA at 3.6 quarters (~1.0 year) of peak earnings implied. More conservative than DOW’s 1.7 years, but still unfavorable risk-reward.1
  • Conflict resolution → return to oversupply. Global PE utilization was in the high-60s to low-70s% before the disruption. China continues to add capacity; BofA does not expect the structural closures (~2mn tonnes) needed to permanently tighten markets.1
  • 2026 pricing peaks mid-year, then fades. BofA models a +35cpp US PE increase through Q2 2026, with contract prices declining in H2 2026 and further into 2027. Year-end 2026 pricing stays above January levels but the trend is decisively lower.1
  • 2027–2028 are the normalized earnings anchor. BofA’s $68 PO is based on 6.0x FY26 EBITDA, also consistent with ~6.5x on 2028 EBITDA — treating 2026 as a cyclical peak, not the run rate.1

Risks

  • Upside: Stronger-than-expected global PE demand; higher crude oil prices boosting product prices while US NGL stays cheap; faster conflict resolution with some structural capacity loss; LYB-specific margin improvement in European operations as trade dislocations correct.1
  • Downside: Lower oil prices compress product prices; higher US natural gas and NGL feedstock costs squeeze spreads; weaker global economic growth reduces PE demand; fast post-conflict normalization accelerates pricing decline before contracts reset lower.1

Recent catalysts

  • 2026-04-06 — BofA downgrades LYB to Underperform from Neutral; raises PO to 55; raises FY26 EBITDA to 532mn. LYB identified as the biggest near-term beneficiary of market dislocations among BofA’s covered petchem universe.1

Second-order reads

  • 2026-04-06 — BofA US Chemicals note — US PE contract-to-spot export spread now at ~8.65cpp; wide differential likely difficult to hold as dislocations normalize. Implication for LYB: near-term earnings beats likely but contract repricing risk builds through H2 2026.1

The 6.0x multiple is a discount to LYB’s historical averages; BofA treats 2026 as a cyclical peak and anchors to 2027–2028 normalized estimates. The PO is also roughly consistent with a 6.5x multiple on 2028 EBITDA.1
