The first sign that HTC has reversed its downward spiral was the unconfirmed info that the HTC One had sold 5 million units not long after its end-of-March launch. Now we get something more official from HTC's monthly financial info, which shows a 48% increase in revenue for May compared to April.

The total revenue for May were $969.6 million, just 3.35% down compared to the same month last year. That's quite the reversal, considering HTC was seeing nearly 50% year on year decrease in revenue in the previous months.

The revenue for the January-May period is $3.06 billion, about $1.4 billion from Q1 and $1.6 billion for April and May. HTC should be able to hit its Q2 projection of $2.3 billion in revenue and even surpass it if the increase in sales holds up in June.
