Does REG FD apply to Warren?

Sure.
But it doesn't apply to this situation, for two reasons.

Mainly, there is no suggestion that anything was disclosed to someone-but-not-everyone, the essence of the rule. Telling the SEC doesn't count!
And of course none of these changes is material to the value of a Berkshire share. The test is "material non-public information".

To break the rule, Mr B would have to (say) sell the railroad to Amazon and tell his barber on the sly.
