What is a filing amendment (the “/A” suffix)?
An amendment — shown with a “/A” suffix like 10-K/A — revises a previously filed report to correct or add information.
When a company revises a filing
An amendment updates a filing a company has already submitted. You'll spot one by the "/A" suffix on the form type — a 10-K/A amends a 10-K, a 10-Q/A amends a 10-Q, and so on.
Why companies amend
- To correct an error or typo in the original.
- To add information that was incomplete or omitted (a common reason 10-K parts are filed shortly after the main report).
- To restate figures when previously reported numbers turn out to be wrong.
How serious is it?
It depends. Many amendments are routine and minor. But an amendment that restates financial results is significant — it means earlier numbers can no longer be relied on, and it often pairs with an 8-K Item 4.02 ("non-reliance on previously issued financials"). FiledFeed flags restated figures clearly so you know when a number has changed.

Amendments appear in the feed with an "amendment" badge, and the filing detail page links back to the original report it revises so you can compare the two.
