AcquiScan

Extract acquisition and subsidiary information from SEC filings.

Features

• No API keys required. AcquiScan works directly with SEC EDGAR's public API. LLM integration is optional.
• Exhibit parsing (exhibits mode) extracts subsidiaries from structured EX-21 and EX-8 exhibit documents attached to annual filings. This mode is fast and deterministic.
• LLM-powered extraction (llm mode) finds acquisition-related excerpts across 10-K, 10-Q, 8-K, 20-F, and 6-K filings using keyword matching, then sends them to an LLM to extract the company name, acquisition date, ownership structure (full or partial), strategic rationale, any rebranding or integration into other products, and subsequent divestitures.
• Date filtering with --from-date and --to-date to scope results to a specific time range for ongoing monitoring.

Modes

exhibits (default)

Parses EX-21 and EX-8 exhibit documents from 10-K/20-F filings to extract a list of subsidiaries.

Coverage

• exhibits parses structured subsidiary lists from EX-21/EX-8 exhibits of 10-K and 20-F filings, but these exhibits only include subsidiaries that are significant enough to require disclosure. Smaller acquisitions and recently completed deals may not appear.
• llm extracts acquisitions mentioned in the narrative text of 10-K, 10-Q, 8-K, 20-F, and 6-K filings and picks up deals that are discussed in context. However, companies are not required to discuss every entity they acquire or own. Acquisitions that were completed quietly may not appear in any filings. LLM responses may also contain inaccuracies and you should treat them as leads for further research.

Installation

pip install acquiscan

On first run, AcquiScan creates a config file at ~/.acquiscan.yaml where you set your SEC user-agent and (optionally) an OpenAI API key.
