Embattled Chinese tech giant Huawei said first-quarter revenue fell after it sold its lower-priced Honor smartphone brand – but profitability has improved.

Sales declined 16.5% from a year earlier to 152.2 billion yuan (£16.9 billion) due in part to lower revenue for its consumer unit, the company said.

It gave no earnings, but said its profit margin improved by 3.8 percentage points to 11.1%.

Huawei, China’s first global tech brand, is struggling to hold onto its global market share following US sanctions that devastated its smartphone sales, which were once among the world’s highest.

The company also is the biggest maker of network gear used by phone and internet carriers.

Washington says the company is a security risk and might facilitate Chinese spying, an accusation Huawei denies.

The sanctions bar access to US processor chips and services including Google’s music and other popular apps.

Huawei designs its own chips, but manufacturers are barred from using US technology required to produce them.

Honor was sold in November in the hopes of reviving sales by separating it from the sanctions on the parent company.

Wednesday’s announcement gave no details of sales by network gear, consumer and other business lines.

Eric Xu, one of three executives who will take a turn as Huawei chairman, said that 2021 “will be another challenging year for us, but it’s also the year that our future development strategy will begin to take shape”.

Huawei has responded by emphasising its sales in China and for electric and self-driving cars, industrial networks and other technology that is less vulnerable to US pressure.

The firm has a stockpile of US chips for high-end smartphones but executives have said these are being used up.

Wednesday’s announcement gave no details of sales by its network equipment or other business lines.

Huawei, headquartered in the southern city of Shenzhen, says it is owned by the Chinese employees who make up half its workforce of 197,000 in 170 countries.

The company began reporting financial results a decade ago to try to defuse western security concerns.

Huawei’s founder, Ren Zhengfei, suggested in a letter to employees the company might considering having one of its business units join a stock exchange for the first time, The South China Morning Post of Hong Kong reported.

Mr Ren warned employees not to falsify accounting numbers, saying that might be a legal issue “if one of our businesses gradually enters the capital market in the future”, the Post reported.

It said Mr Ren gave no indication the company has such a plan.

Huawei reported earlier its sales of phones, network gear and other technology rose 3.8% in 2020 over a year earlier to 891.4 billion yuan (£97.7 billion), but that growth was down from 2019’s 19.1%.
