TOKYO (Reuters) - Demand for hybrids is likely to deliver another quarter of double-digit growth for Japan's Toyota Motor ( TM ) when it reports earnings on Thursday, although it is expected to show signs of slowing after a run of record profits.

Analysts will be paying close attention to how much momentum the world's top-selling automaker has lost from previous quarters, given challenges like a tough market in China and fallout from a certification scandal.

Sales data already give a hint of the potential slowdown. Toyota's ( TM ) global sales declined 2% in April-June versus a year earlier as robust U.S. and European demand wasn't enough to make up for declines at home and in China.

For the April-June quarter, Toyota ( TM ) is expected to deliver a 20% rise in operating profit to 1.3 trillion yen ($8.50 billion) the average prediction of six analysts shows, as per LSEG.

That would be the company's weakest profit growth since July-September 2022. The automaker has already forecast a 20% decline in full-year profit, citing looming investment in both its strategy and suppliers.

Toyota ( TM ) has benefited from a slowdown in global demand for electric vehicles, allowing it to sell more hybrids, which typically command higher margins than regular gasoline cars.

The company's inventories in the U.S. are also tight, reducing the risk of incentive spending to entice customers to buy cars, said James Hong, head of mobility research at Macquarie.

"You basically have one of the largest market players with the lowest level of inventory," he said, adding that, together with the company's growing hybrid offering, was likely to help keep earnings at a high level.

Hybrids made up 39% of Toyota's ( TM ) global sales in the first six months of the year, or 1.9 million vehicles, including the luxury Lexus brand, according to company data.

The strategy to boost hybrid sales in the U.S. over the short term instead of battery-electric vehicles might also shield it from potential changes in U.S. government policy on EVs.

Former President Donald Trump, the Republican candidate in the U.S. presidential election, has said he would end the government EV mandate if he wins.

Shares of Toyota ( TM ) are up 13% so far this year, but have not performed well over the past months, coming down 25% from a peak in late March.

In dollar terms, they are up 6%, compared to a 10% decline in Tesla over the same period.

Toyota's ( TM ) strong financial performance and gains in its share price belie pressure that Chairman Akio Toyoda has faced over certification irregularities at Toyota Group companies and the automaker itself.

In an interview published on Monday, the grandson of the company's founder said he may not be re-elected as a board director if shareholder support for him, which slid to 72% this year from 85% in 2023, continues to fall at the pace it did.

While strong in hybrids, Toyota ( TM ) still trails behind rivals such as Tesla and European and Chinese automakers when it comes to EVs, which accounted for only 1.5% of its global sales in the first half of the year.

Toyota's ( TM ) China sales were down 11% to 785,000 vehicles over the first six months of 2024, compared to a 14% gain to 1.2 million vehicles in the U.S over that period.
