SEC filings & market structure

Tender Offers (Schedule TO)

Returns SEC Schedule TO filings — public tender offer disclosures. Use this when the user asks about: who's bidding to acquire company X, what M&A offers are in flight, share buyback announcements, amendments to existing tender offers (price increases / extensions), or to pair with 13D activist stakes for the 'stake → bid' story.

Filters

accession_number	EDGAR accession number (e.g., '0001140361-26-020397'). Direct doc lookup, fastest path.
target_ticker	Target company ticker (e.g., 'KZR'). For SC TO-T this is the company being bid for; for SC TO-I this is the company buying back its own shares…
target_cik	Target's SEC CIK (10-digit zero-padded). Use when ticker is ambiguous (multiple share classes).
target_name	Case-insensitive substring against target_name. Useful when ticker isn't known (e.g., private companies in TO-T filings).
bidder_cik	Bidder's SEC CIK. Find all tender offers by a particular acquirer.
bidder_name	Case-insensitive substring against bidder_name. Bidders in SC TO-T are often private SPVs ('2025 Acquisition Company, LLC') — use this to find them…
form_type	Exact form match. Useful for narrowing to amendments only ('SC TO-T/A') or original offers only ('SC TO-T').
third_party_only	When true, restricts to SC TO-T family (third-party offers). Default false.
issuer_only	When true, restricts to SC TO-I family (issuer buybacks). Default false.
exclude_amendments	When true, drops /A amendment filings. Default false (amendments included).
since	Filing date lower bound (ISO YYYY-MM-DD inclusive).
until	Filing date upper bound (ISO YYYY-MM-DD inclusive).
sort_order	Default: desc (most recent filings first).
limit	Maximum filings to return. Default 50, max 500.
