The company, which supplies Tesla Inc, General Motors Co and others, reported an operating profit of 633 billion won ($472.6 million) for the January-March period, versus 259 billion won a year earlier.

That compared with an average analyst forecast of 633 billion won compiled by Refinitiv SmartEstimate.

Revenue for the quarter rose 101% to 8.7 trillion won, LG Energy said in a regulatory filing.

Analysts attributed the jump to the solid sales of EVs in the United States, where EV consumers could receive up to $7,500 U.S. EV tax credit under the Inflation Reduction Act, which would help boost sales of EVs.

The U.S. Inflation Reduction Act requires 50% of the value of battery components to be produced or assembled in North America to qualify for a $3,750 credit and 40% of the value of critical minerals sourced from the United States or a free trade partner also for a $3,750 credit.

About 80% of EVs that are eligible for U.S. federal tax credits use batteries from South Korea's three major cell makers - LGES, Samsung SDI Co Ltd and SK On, according to an analysis from brokerage Korea Investment & Securities.

Shares of LG Energy Solution was trading up 0.7%, versus benchmark KOSPI's 0.1% rise as of 0044 GMT.
