After the market closed, Woodward came out and categorically denied the WSJ's report, saying that it was not in talks. Period.
Its not necessarily nefarious, but the WSJ does in fact publish stories that rely on questionable sources. It's absolutely not out of the question that that could have happened here as well.
Note that since [1] was published, Woodward has not been acquired by Boeing, and its stock took a dive after the WSJ's poorly sourced story caused the stock to shoot up ~10% when it published. A lot of people that bought it on the WSJ's bad report lost a lot of money.
