It’s not been a good start to the launch of the HTC One, due mainly to delays caused by supply shortages with the Ultrapixel camera components. Sadly, HTC’s woes are set to continue as the HTC One is still facing component shortages, which are expected to last until the end of April. The component shortage is now becoming a major concern for HTC and the company’s investors, as it’s starting to take a toll on sales and revenue.

The continued stock shortages are leading many to suspect that the HTC One will miss its first quarter sales targets. Investment services firm Macquarie Securities has lowered its shipping forecasts for the HTC One to between 1 million and 1.5 million units, down from 1.5 million to 2 million units, which is a pretty substantial drop.

Macquarie Securities is also expecting HTC’s consolidated sales between January and March to only reach NT$48 billion (New Taiwan dollars). That might sound like a lot of money, but to put this in perspective HTC gave an initial sales target of NT$50 billion-NT$60 billion for the first quarter back in February.

JP Morgan Chase has also echoed these expectations, forecasting HTC’s total revenue to come in at NT$45 billion for the first quarter and further sales problems in the second quarter if the component shortages cannot be resolved by late April.

In light of the looming launch of the Samsung Galaxy S4 you can understand why HTC is starting to feel the pressure. The heat is especially felt by the company’s CEO and president Peter Chou, who reportedly promised to resign if the HTC One flops.

Hopefully HTC can pick up the pieces and put everything back on track soon. After all the HTC One is a really good smartphone.
