Scroll to zoom. Drag to pan. Click any marker to open the BOMForge company profile or primary-source SEC filing. Filter chips above subset by event class. Timeline below scrubs by date — auto-plays on load. Note: "8-K" categories are SEC corporate filings made by public companies about their own activity (acquisitions, plant closures, bankruptcies, carve-outs, add-ons); they are events on the manufacturer, not necessarily PE deals. Hand-verified PE portfolio companies are marked ★.
About this data
This atlas plots 3,764 events affecting US manufacturers between January 2020 and April 2026. Every dot carries a primary-source URL. Working draft; do not cite without independent verification.
Substrate composition
3,706 SEC EDGAR 8-K filings — public companies disclosing corporate events (acquisitions, bankruptcies, plant closures, carve-outs, add-ons). Click any "8-K" dot to open the direct filing-index page on SEC.gov (the actual 8-K document, not a search).
22 verified PE portfolio companies (★) — manual portfolio crawl across American Industrial Partners, KPS Capital, Platinum Equity, and Genstar. Each carries an acquisition year + exit type. 20 of 22 have Wikipedia entries linked. One additional portco (Princess Yachts UK) honestly dropped from the US map.
24 verified asset-manager M&A deals — BlackRock → GIP ($12B), BlackRock → HPS ($12B), Brookfield → Oaktree, T. Rowe → Oak Hill, etc. Each with 3-4 primary-source URLs (CNBC, Reuters, law firm announcements).
12 additional PE-backed manufacturers — companies flagged pe_backed=true in BOMForge production not already surfaced via the above.
Time window
The substrate covers January 2020 – May 19, 2026. The EDGAR 8-K crawler was re-run this session and added 117 new events for the May 1-19 window (mostly acquisition disclosures plus 14 Chapter 11 filings). DB max date verified at 2026-05-19. Press-release enrichment of the May events is queued (Google News RSS rate-limited the re-pass after the 3,400-event bulk run; will retry in a separate session).
Pre-2020 filings (the 2015-2019 Carlyle / KKR / Apollo LMM rollup wave; the 2008-2010 financial-crisis distress events; the late-1990s LBO boom) are not in the EDGAR substrate — the original crawler ran with a 2020-01-01 start date. Verified portcos go back further (Heil Trailer 2011, Carlstar Group 2013) because they were hand-curated independently of the EDGAR crawler. Pre-2020 EDGAR backfill is a Phase 2 work item.
Honest caveats
Filer-self-8K contamination. All 3,706 SEC EDGAR rows have target_name == acquirer_name — they're public companies filing 8-Ks about their own activity (Stanley Black & Decker filing about its own plant closure; Mallinckrodt filing about its own Chapter 11). These are real signals about industrial-base distress, but they are NOT "PE acquired this company" deals. Tooltips disclose this explicitly when you click a self-filing dot.
Geocoding. Verified portcos use hand-curated locations (e.g. Briggs & Stratton → Wauwatosa WI). 8-K events use the filer's address from EDGAR or the linked manufacturer's city/state. No state-centroid fallback — events that couldn't be geocoded are dropped, not faked.
Substrate vs. cohort. Prior versions of this page led with an n=188 "PE-backed manufacturer mortality" cohort claim. That filter is the most conservative possible slice of the data (pe_backed=true AND NAICS 31-33) and the page no longer leads with it; numbers carried over from earlier dossiers should not be inferred from what's plotted here.
No press-release or news-article enrichment. Source URLs are either SEC EDGAR (direct filing pages, not search) or the 24 alt-manager rows' hand-curated press URLs. We have NOT cross-referenced PR Newswire, Business Wire, WSJ, Bloomberg, or local newspapers — those require licensed APIs or fragile scraping. Wikipedia for verified portcos is the closest news-equivalent we ship today.
Filter chips & lenses
★ PE-owned mfg (LMM) — subsets to the 22 verified portcos + 12 pe_backed mfg + active-under-PE manufacturers. Excludes the 3,706 8-K corporate self-filings. This is the lower-mid-market verified-PE cohort — the cleanest cut for "who owns what" analysis. ~34 dots, all hand-verifiable.
★ PE portco bankruptcy / secondary exit / active / consolidated — sub-cuts of the 22 verified portfolio companies by exit status.
Bankruptcy / Plant closure / Acquisition / Carve-out / Add-on (8-K) — SEC corporate filings, NOT PE deals. Use these for industrial-distress signal mapping, not PE-acquisition counts.
Asset-manager M&A — financial-industry consolidation (BlackRock buying PE firms, etc.). Adjacent to PE but not "PE acquired a US mfg."
