The only thing I can think of at the moment is this line:
"Q2 Revenue are expected to total $0.6M, in line with the revenue reported in the same quarter a year ago." (No change in revenue YOY)
Maybe that's causing some hesitation. But it makes no sense as the last line spells it out plainly:
"As a reminder,a majority of Resonant’s revenuesare based onprepaid royalty contracts, which generate immediate cash but may have delayed revenue recognition."
