Participial Phrase as Verb Modifier?

On the internet, I only read about participial phrases acting as noun modifiers.
But when I read various newspaper articles, it seems that participial phrases are also used as verb modifiers, or even as clause modifiers.

• Suggested example for verb modifier: He came to town, driving in his new car.
• Suggested example for clause modifier: EQZCO posted a quarter loss of $10 million dollars, causing its stocks to decrease by $5 per share.

Can that be?
