Celtic Pharma
Celtic Pharma, founded in 2004, acquires pharmaceutical royalties and late-stage drug assets for institutional investors from its London base.
Celtic Pharma
Celtic Pharma was founded in 2004 by Stephen Evans-Freke, a veteran biotechnology financier who previously co-founded SG Cowen's healthcare banking franchise, alongside John Mayo, the former finance director of Glaxo Wellcome. The firm emerged from the premise that pension funds and sovereign wealth investors needed a specialized vehicle to access pharmaceutical royalties and late-stage clinical assets — a strategy distinct from traditional biotech venture capital. Evans-Freke had already established a track record in the space through Royalty Pharma, the dominant player in drug-royalty acquisitions, and Celtic became a separate, actively managed platform operating from London. The firm acquires royalty streams, revenue interests, and direct ownership stakes in approved and Phase III pharmaceutical products. Target assets include therapies for oncology, infectious disease, and neurology. Celtic Pharma does not operate as a fund-of-funds and rarely participates in early-stage venture rounds; it underwrites the regulatory and reimbursement risk on single assets, structuring transactions directly with originator biotech companies or their lenders. Confirmed historical positions include royalties on ustekinumab (Stelara) and certolizumab pegol (Cimzia), both blockbuster immunology drugs (public record, per EvaluatePharma). The firm's geographic focus centers on products approved in the United States and major European markets. Team size and total deployment remain undisclosed. The firm has not raised blind-pool funds in the traditional private equity model; it structures transactions on an asset-by-asset basis. This architecture allows Celtic to bypass the fundraising cycle and align capital calls with specific milestones. In recent years, the firm established Celtic Pharma Management LP, a Delaware-registered entity, to manage certain US-facing royalty acquisitions — a structural adaptation to a portfolio increasingly weighted toward North American assets (public record, per SEC filings). No adjacent philanthropic vehicles or membership clubs have been disclosed. The firm's structural distinction lies in its pure-play asset finance model. Unlike most healthcare private equity managers that take equity in operating companies — with their attendant clinical, regulatory, and management burdens — Celtic underwrites specific drug revenue curves. This allows pension fund and sovereign wealth allocators to access pharmaceutical cash flows without the J-curve dynamics of traditional biotechnology fund commitments. The approach leans heavily on the actuarial pricing of FDA-approved or advanced-stage products, a skill set that more closely resembles specialty insurance underwriting than venture capital portfolio management.

Frequently asked questions
Who runs investment decisions at Celtic Pharma?
Stephen Evans-Freke and John Mayo are the firm's managing directors. Evans-Freke built his career in healthcare investment banking at PaineWebber and SG Cowen before co-founding Celtic in 2004. Mayo was group finance director of Glaxo Wellcome and later Marconi plc. The two principals jointly approve all asset acquisitions, per the firm's official communications.
Is Celtic Pharma structured as a single family office or does it operate more like a venture firm?
Neither. Celtic Pharma is a specialized private equity firm that acquires pharmaceutical royalties and late-stage drug revenue interests. It does not manage family wealth, and it does not operate as a traditional venture capital firm making equity investments in early-stage biotechs. The firm underwrites specific drug assets, structuring transactions as royalty acquisitions or revenue-interest purchases directly from originator companies.
Does Celtic Pharma participate in fund commitments or only direct deals?
Celtic Pharma does not raise closed-end blind-pool funds and does not invest as a limited partner in other managers. The firm structures transactions on an asset-by-asset basis, matching institutional capital to specific drug-royalty or revenue-interest acquisitions. Investors participate through vehicles established for individual assets rather than through a pooled fund commitment.
What investment stages does Celtic Pharma typically target?
The firm targets pharmaceutical products that are already approved or in Phase III clinical trials. Celtic underwrites the regulatory and reimbursement risk on therapies nearing or in commercialization, avoiding early-stage drug discovery and preclinical assets. This late-stage focus is designed to reduce binary clinical-trial risk for institutional allocators.
How is Celtic Pharma related to Royalty Pharma?
Stephen Evans-Freke was a co-founder of Royalty Pharma in the 1990s before establishing Celtic Pharma in 2004 as a separate, actively managed platform. The two firms are independent entities, though both operate in the pharmaceutical royalty acquisition space. Celtic is significantly smaller and structures deals on a more bespoke, asset-by-asset basis compared to Royalty Pharma's publicly traded, large-scale aggregation model.
