CordenPharma is one of the three large peptide contract development and manufacturing organizations supplying the GLP-1 and broader peptide-therapeutics pipeline, alongside Bachem and PolyPeptide. The company operates a multi-site network across the US (Boulder Colorado, Plankstadt Germany), Europe, and Asia, with peptide-specific capacity concentrated at Boulder. In 2024-2025, CordenPharma announced a $500M+ investment to more than double the Boulder site's solid-phase peptide synthesis (SPPS) reactor capacity — adding 25,000L of SPPS capacity to reach a total of more than 42,000L by 2028.
The capacity build targets the incretin demand wave: semaglutide and tirzepatide active pharmaceutical ingredient at commercial scale, plus the early-stage pipeline of retatrutide, amycretin, NK2R agonists, and peptide-drug conjugates that will need GMP scale-up over 2026-2030. CordenPharma's TIDES USA 2026 presence in Boston May 12-14 centered on large-scale SPPS economics and the macromolecule supply chain question. The company is also building out its first-in-human peptide injectable services (PepCellerate™) for the clinical-stage cohort.

AmbioPharm announced June 16 a $118.96 million expansion of its Aiken County, South Carolina headquarters, adding a 68,000-square-foot modular manufacturing building at its existing 1024 Dittman Court campus in North Augusta and creating more than 200 new jobs. The facility will offer commercial-scale GMP synthesis including solid-phase peptide synthesis (SPPS), liquid-phase peptide synthesis (LPPS), and hybrid approaches, mirroring upgrades made to AmbioPharm's Shanghai facility. Operations target end of 2027. The announcement arrives roughly three weeks after the May 27, 2026 close of CordenPharma's acquisition of AmbioPharm, which secured CordenPharma a second US peptide site (joining Boulder, Colorado) and its first Shanghai-based supply node. AmbioPharm shareholders are reinvesting in the combined entity. The expansion is the largest single US peptide-manufacturing capacity addition of 2026 to date.
SNS Insider published its 2026 Peptide Synthesis Market Report on Tuesday May 19, projecting the global peptide synthesis market to reach $1,889.88M by 2035 from current levels, anchored on GLP-1 receptor agonist demand and the broader peptide therapeutics pipeline. The report tracks the major SPPS capacity expansions: CordenPharma's $500M+ Boulder Colorado site adding 25,000L+ to reach 42,000L total by 2028, Bachem's three-site expansion (Bubendorf Switzerland, St Helens UK, Vista California) plus a new Sisseln Switzerland facility, and PolyPeptide's €200M credit facility supporting the doubling of 2023 revenue by 2028. The structural read: incretin-class peptide demand (semaglutide, tirzepatide, retatrutide, mazdutide, survodutide, eleglipron) plus the next-generation pipeline (NK2R agonists, amylin combos, peptide-drug conjugates) is the demand wave the CDMOs are positioning against.
TIDES USA 2026 wrapped at the Hynes Convention Center in Boston on Thursday May 14 after four days of peptide and oligonucleotide CDMO programming. The CMC strategy tracks featured Bachem, PolyPeptide, CordenPharma, AmbioPharm, and Gilead on GMP capacity, large-scale SPPS economics, and the supply-chain economics of oral macromolecule manufacturing. The closing-day Robert Langer keynote framed peptide-LNP delivery as the next major engineering frontier. The conference concluded with Catalent's Zydis fast-dispersion + oral macromolecule platform presentations and Novo Nordisk's CMC strategy panel on oral semaglutide and the next-generation amycretin program. The week's combined manufacturing footprint (TIDES + the PolyPeptide EUR 200M credit facility on May 9 + the May 6 Lilly Lebanon $4.5B investment) anchors the CDMO buildout heading toward the 2028 capacity targets.
CordenPharma's Boulder, Colorado expansion is now confirmed at $500 million, with the first phase coming online in 2026 and full completion in 2028. The site will add new large-scale manufacturing lines and a greenfield facility that more than doubles its solid-phase peptide synthesis (SPPS) capacity to over 42,000 liters by 2028 — positioning Boulder among the largest peptide production sites worldwide. CordenPharma Colorado leased 64,000 square feet at BioMed Realty's Flatiron Park 5505 Central — Boulder's first purpose-built speculative lab building — and will add more than 200 employees to the existing 700-person workforce. The expansion sits within CordenPharma's broader €900M+ ($1B+) global peptide platform investment that also includes a >€500M greenfield site near Basel.
