HTC saw its monthly revenue in May surpass NT$40 billion for the first time in the company’s history. Taiwan Economic News reports on Thursday that HTC’s May revenue came in at NT$40.6 billion, or US$1.6 billion, thanks to continued high demand for its smartphones. Revenue was up 115% compared to the same month last year, and up from NT$38.73 billion last month, which had also set a company record.
