Pegatron Corp., one of Apple’s iPhone assemblers, on Friday reported that first-quarter revenue declined 33.38 percent from the previous quarter and was 5.31 percent lower than a year earlier.

Consolidated revenue in the January-to-March period totaled NT$278.49 billion (US$9.25 billion), compared with NT$418.01 billion in the previous three months and NT$294.11 billion a year earlier, the electronics manufacturer said in a regulatory filing.

Besides handsets, Pegatron manufactures notebooks and desktop computers, wearable devices and game consoles, for companies inclusing Apple, Sony Corp, Microsoft Corp and Asustek Computer.

Pegatron is expected to see a sequential increase in revenue this quarter, as it last month resumed full production in China and is ready to produce new products for clients, as well as orders from the first quarter that were delayed due to COVID-19. The company expects its second-quarter revenue to grow 18 percent from the first quarter to NT$324.2 billion.

The COVID-19 pandemic has also an impact to Quanta Computer’s first-quarter revenue, which was decreased 36.02 percent quarterly and 14.04 percent annually to NT$190.264 billion -- its lowest in 10 years.

Quanta said that the pandemic had an impact to its laptop production in China in the first quarter, but the companby expects laptop and server shipments to grow this quarter after production resumes at its Chinese plants.

Other major contract electronics manufacturers also reported an annual decline in sales last quarter as the coronavirus outbreak affected shipments, with Inventec Corp’s revenue decreasing 22.8 percent to NT$88.58 billion, Wistron Corp’s falling 15.8 percent to NT$173.68 billion and Compal Electronics Inc’s dropping 13.56 percent to NT$182.05 billion.
