CDMO Signal tracks 158 biopharma CDMOs with confirmed United States manufacturing facilities, of which 84 are fully scored across the four-pillar composite Signal Score. Across all modalities, Pfizer CentreOne, Bristol Myers Squibb (CGT Mfg), and Pharmaron lead the United States ranking by composite score. Signal Score integrates FDA inspection history, EMA/MHRA GMP certificate density, ClinicalTrials.gov sponsor footprint, and monitored capacity signals. For modality-specific rankings within United States — AAV, cell therapy, biologics, and 10 other tracked modalities — see the modality-region breakdown below. Full methodology at cdmosignal.com/methodology.
US-based CDMOs ranked by CDMO Signal's composite Signal Score, filtered to manufacturers with confirmed United States facilities. This ranking is the subset of our global directory with US manufacturing presence — a CDMO with US + EU + Asia sites appears in each corresponding region ranking. Filtering is derived from each CDMO's declared facility locations.

FDA jurisdiction — how the ranking scores US-based CDMOs
The Signal Score's Quality Compliance pillar (35% of the composite) is dominated by FDA inspection data for US-based CDMOs: Establishment Inspection Report classifications (NAI, VAI, OAI), Form 483 observation counts, and Warning Letter history. For a CDMO whose primary facility footprint is US, this pillar carries direct weight — an inspection on the site slated for a sponsor's program applies without translation. For CDMOs with mixed US + international facility footprint, the ranking reflects the composite regulatory posture; sponsors evaluating for a specific program should verify inspection history on the exact US site under consideration via that CDMO's profile page.
Which US CDMOs also cover EU and UK regulatory geographies?
Many top-tier US-based CDMOs maintain EU (EMA) and UK (MHRA) GMP certification for facilities used to supply EU and UK trials or commercial markets. The Signal Score's Quality Compliance pillar includes EMA + MHRA certificate density as a component — a US-headquartered CDMO with dense EU/UK certificates typically ranks higher on this pillar than a US-only competitor. Sponsors running dual-jurisdiction programs should cross-check the individual CDMO profile pages for specific certificate coverage; the Europe region ranking surfaces CDMOs that also appear in the European jurisdiction ranking, indicating multi-region regulatory posture.
How CDMO Signal identifies US manufacturing presence
Region attribution is derived from each CDMO's declared facility locations in our directory. A CDMO's facility list is validated against corporate filings, press releases, and — where public — the FDA facility registration (FEI number lookups). Region matching is done at the country level: a US state name or two-letter abbreviation in the facility list places the CDMO in the US region. CDMOs with US + international sites appear in every applicable region ranking, which reflects operational reality — such a CDMO is a legitimate candidate for programs in any of those jurisdictions.
