Now the public knows how much cloud file-sharing company Box recently spent to pick up two-man medical-imaging software startup MedXT.

Box paid out new stock shares worth $3.84 million to do the acquisition, according to a document Box filed today with the U.S. Securities and Exchange Commission.

“Beyond this filing, we’re not disclosing the terms of the transaction, but can confirm this Form D is specific to the deal,” a Box spokesman told VentureBeat in an email. It’s unclear if the exit included additional compensation, like bonuses.

The amount might be a nice exit for MedXT’s Cody Ebberson and Reshma Khilnani, a couple of years after the Y Combinator-backed startup began. But Box needs to watch its spending ahead of an initial public offering, whenever that might come. The company has a history of net losses, and it’s in Box’s best interest to keep its finances looking good once it does hit public markets.

Then again, it’s also smart for Box to bolster its capabilities in health care-related technology. That’s because health care represents one of the top areas of focus for Box. So young startups might be just perfect fodder for this Los Altos, Calif.-based company.
