Disney doesn't have to provide the vote total. All they need to do is say something like:
The numbers cited by your source are erroneous, and not reflective of the actual voting tallies. We remain committed to ensuring competent board leadership, and avoiding the distraction that these baseless figures create.
And like that, Disney has clarified that the source is bunk WHILE avoiding giving specifics. But instead, Disney decided to attack the individual who leaked them. Not the substance of the leak, but the character of the leaker. Alternatively, if the lawyers are a little squeamish over that, Disney could follow a different strategy:
The Walt Disney Company refuses to comment on the validity of these specific figures, but we do encourage your readers to be skeptical of any unverified data. If our shareholders or the media are interested in learning about this proxy fight, please visit thewaltdisneycompany.com and votedisney.com. The Walt Disney Company remains focused on ensuring that our qualified list of candidates are successful in our upcoming shareholder meeting.
This move is also effective, because Disney has not commented at all on the voting tally. But they still manage to put it under a cloud of suspicion. It's "unverified" and therefore suspect, whether or not it's true. They could also pull the following:
We are dismayed to see that supporters of Trian's nominees seem to be spreading rumors about the voting tallies. For official information on the proxy fight, please visit thewaltdisneycompany.com and votedisney.com. We are confident that our highly qualified board nominees will be victorious.
This is also a good one, because the rumors could be true or untrue. But after you have labelled something a "rumor" anyone will question it and take it as suspicious. Instead, they went with the following:
While we don't have the full quote, it seems like we didn't get a strong denial or even a hint of doubt being thrown over the figures. That suggests either the spokesman was shooting from the hip (a mistake), or they didn't want to actually cast doubt on the figures because they're real. Disney also could have updated their votedisney.com website if they felt their comment had been misconstrued by the WSJ.
But ultimately, each individual can make up their own determination.
