10-K risk factors (Item 1A), filed 2025-09-18 to 2026-09-17

Which 10-K filers newly named tariff exposure as a risk

We read each 10-K's risk factors against the same company's filing a year earlier and record who names tariffs as a new risk.

Named tariff exposure as a risk for the first time this year
333
Comparable filers, both years read
4,551
Name tariff exposure as a risk
3,731

Three counts, one denominator

Each bar is out of the 4,551 comparable filers. A keyword search finds the first. The second needs this year's paragraphs read, and the third needs last year's read the same way. The ochre bar is the first-time count.

How it was counted

Every comparable 10-K filer, this year against last

Per-company tools show what one filer changed. This covers every comparable 10-K filer against its own prior 10-K, including those that disclosed nothing, so every count arrives with its denominator.

Four editions a year, on 15 March, 30 April, 31 July and 31 October. Each covers every filer's latest 10-K in the trailing twelve months, compared with its prior 10-K.

Licence terms

Why this is not the free version

A keyword search finds 3,841 filers that mention tariffs. Only reading both years finds the 333 that named it for the first time.

Free alternatives are hand-picked lists of a few dozen companies, each with a quotation. They state no denominator and make no comparison with last year. This covers every comparable 10-K filer in the window, states how many there are, separates a new disclosure from a carried one, and counts, per SIC group, the peers who did not. The filings themselves are free from EDGAR; reading all of them is the work.
