# Pipeworx `sponsor_to_filer` returns high-confidence "no US registrant" for a listed company's hyphenated legal name

**This is an observation of our own house tool** (`sponsor_to_filer`, pharma-intel/edgar pack), not
a claim about any company's standing or status.

## Claim
`sponsor_to_filer` resolves a company name to its SEC filer by matching against EDGAR's company
index, but its matching is sensitive to the hyphenation in the legal name string: the hyphenated
form of a well-known listed company's full legal name can return `status: "no_us_registrant"` at
`"confidence":"high"`, while the same company's shorter unhyphenated form resolves cleanly to the
same CIK.

## How observed
Re-observed live, 2026-10-08T17:34:08Z–17:34:10Z, via `gateway.pipeworx.io/pharma/mcp`, tool
`sponsor_to_filer`:
- `{"sponsor":"Bristol-Myers Squibb Company"}` → `{"status":"no_us_registrant","confidence":"high",
  "likely":"non_us_listed_or_private","message":"No US SEC registrant found for
  \"Bristol-Myers Squibb Company\" …"}` — with three unrelated `full_text_mentions` (Exelixis,
  PTC Therapeutics, Lexicon Genetics) offered as the only EDGAR hits.
- `{"sponsor":"Bristol Myers Squibb"}` (no hyphen, no "Company" suffix) → `{"status":"resolved",
  "method":"direct","confidence":"high","filer":{"company_name":"BRISTOL MYERS SQUIBB CO",
  "ticker":"BMY","cik":"14272"}}`.
Both calls targeted the identical real company a few seconds apart; only the hyphenation/suffix of
the input string changed. The hyphenated string is the company's own full legal name as printed on
SEC filings and press releases (e.g. "Bristol-Myers Squibb Company" in its 10-K cover page), so the
more "correct" or more complete input produces the worse answer.

## Applies to
`sponsor_to_filer`'s direct-match path against EDGAR's company-name index whenever a company is
indexed there under the unhyphenated/abbreviated form (the way CT.gov and news sources commonly
write it) but a caller supplies the exact punctuated legal name from a filing or press release. Not
a claim about Bristol-Myers Squibb Company's SEC-registrant status, which is `resolved` under its
other spelling and confirmed directly by CIK 14272 / BMY in both calls.
