What Gannet BioChem does
Gannet BioChem is a specialty Contract Development and Manufacturing Organization (CDMO) providing custom polymer science services for complex therapeutics. The company's core capabilities span activated polymers, polyethylene glycol (PEG) chemistry, and bioconjugation, supporting therapeutic developers from early discovery through clinical development and commercial cGMP manufacturing. End markets include PEGylation of proteins, peptides, and small molecules, polymer-enabled drug delivery, and medical device polymer applications. Gannet BioChem is headquartered in Huntsville, Alabama in a 124,000+ sq. ft. FDA-inspected facility with seven manufacturing suites scaling up to 800L, supplemented by a 16,000 sq. ft. FDA-registered activated PEG manufacturing facility in Arab, Alabama acquired via the January 2026 Laysan Bio transaction.
The company's technology platform is built on more than three decades of PEG chemistry expertise originating with Shearwater Polymers (founded 1992 by Dr. Milton Harris) and continued through Nektar Therapeutics, from which Gannet was spun out in 2024. Differentiated capabilities include PEG architectures spanning <500 Da to ~60 kDa across linear, branched, multi-arm, and forked configurations; polymer-specific analytical methods (MALDI-TOF, GPC/SEC, qNMR, LC-MS); process development tools (EasyMax reactors, AKTA chromatography, preparative HPLC, small-scale agitated filter dryers); and cold-chain storage at 2–8°C, -20°C, and -80°C. The company has supported 9 FDA-approved therapies and reports a 100% on-time, in-full delivery record across PEG reagent manufacturing programs.
The business model combines two revenue streams: (1) custom CDMO services (process development, analytical method development, cGMP manufacturing) sold through enterprise direct sales to pharma and biotech customers, priced via quote-based custom and cGMP contracts; and (2) catalog PEG reagent product sales (monofunctional, bifunctional, heterobifunctional, multi-arm, and specialty reagents) priced from $24 to $1,200 per unit via a self-service online storefront at catalog.gannetbiochem.com. Distribution is global, with domestic FedEx overnight and international priority shipping. The company is privately held and backed by Ampersand Capital Partners, a Boston-based healthcare-focused private equity firm with $3 billion in assets under management.
