What is DEFA14A?

DEFA14A covers additional soliciting materials a company files after or alongside its definitive proxy statement: supplements that correct or update the proxy, letters to shareholders, investor presentations, website content and press releases about the vote.

During contested elections and close say on pay votes, companies file DEFA14A materials almost daily, which makes the feed a record of how management argues its case. Merger announcements also produce DEFA14A filings when communications relate to a future vote.

Who files

Companies soliciting proxies that send additional written materials to shareholders.

When it is filed

No later than the date the material is first sent or used, under Rule 14a-6(b) and (c).
