July 31 (Reuters) - Petrochemicals manufacturer

LyondellBasell on Friday beat Wall Street estimates for

second-quarter profit, as global supply disruptions lifted

polymer margins, and increased operating rates at its North

American assets.

LyondellBasell said geopolitical instability created

supply-constrained conditions across its businesses, driving

higher polymer margins and favorable co-product pricing.

Here are some details:

* The chemicals maker operated its North American olefins

and polyolefins assets at about 90% utilization during the

second quarter.

* It reported adjusted earnings of $4.30 per share for the

quarter ended June 30, compared with analysts' average estimate

of $3.41 per share, according to data compiled by LSEG.

* Quarterly sales rose 20% to $9.18 billion from a year ago,

narrowly exceeding estimates of $9.15 billion.

* Shares of LyondellBasell were up 3.19% in premarket

trading following the results.

* Net income for the quarter rose to $559 million, or $1.71

per diluted share, from $115 million, or 34 cents per share, a

year earlier.

* Results also improved at its Europe, Asia and

international olefins and polyolefins business, helped by

stronger polymer spreads and joint venture contributions.

* Higher margins for oxyfuels, methanol and propylene oxide

derivatives lifted earnings in its intermediates and derivatives

segment.

* The company said an unplanned outage at its Bayport PO/TBA

plant partly offset those gains. The facility restarted in June

and exited the quarter at full operating rates.

* LyondellBasell completed the sale of four European assets

in the quarter, recording a $734 million pre-tax loss on the

divestiture.

* The company remains on track to generate $500 million in

incremental cash by the end of 2026 through fixed-cost cuts and

lower capital spending.

* It warned that uncertainty over when conflict-disrupted

Middle East supply would return could keep energy and

petrochemical markets volatile into 2027.
