The company's CEO and president claimed that increasing digital sales has had no negative impact on print comics and graphic novels.
Up from "insignificant" revenues from digital in the previous year, Adams revealed that the newer medium is now making "almost exactly" 10% of its equivalent direct market revenue.
"There's just no question at this point that selling comics digitally is definitively not impacting [print] comic book sales," Adams told ICv2.
"If anything you could make the argument that the success of digital is driving more print comic book sales. The correlation at this point is that increased digital has resulted in increased print.
"Whether or not that is a direct correlation, I don't know how you would figure that out. I can say with no uncertainty that our increased digital revenue has come at a time when we've had increased comic book sales."
IDW's direct market sales were up 25% over the last year.
The publisher announced its move to comiXology in December 2011, with all its major titles receiving simultaneous print and digital releases.
