Case Study

San Diego's Life Sciences Cluster

EXECUTIVE SUMMARY

San Diego has become one of the most active global acquisition destinations for pharmaceutical and biotech companies seeking the next generation of medicine. From 2021 through 2025, international pharmaceutical companies (from Switzerland, Germany, France, Japan, Belgium, Sweden, and Italy) committed more than $20 billion in acquisition and licensing activity targeting San Diego life sciences companies.1 The Novartis acquisition of Avidity Biosciences ($12 billion, completed February 2026) is the headline.2

The story underneath is more important: seven nations, a dozen confirmed transactions, and the most documented example of acquisition interest converting into permanent presence: Novartis made so many acquisitions here that it decided to build its own $1.1 billion global research center.3 Bayer's Vividion, acquired for $1.5 billion in 2021, has expanded to 270 employees in a new San Diego headquarters.4 M&A interest is producing retained capital and jobs, not just transaction headlines.

This case study examines the flywheel, and the City's role in accelerating it, through three frames:

Novartis is the proof: three acquisitions, then a $1.1 billion research center. The question is whether the region builds the conditions for the next Novartis to follow the same path.


SAN DIEGO LIFE SCIENCES BY THE NUMBERS

$20B+ International M&A
(2021-2026)
7 Source Nations
$1.1B Novartis Greenfield
71,448+ Direct Jobs

San Diego is the third-largest US biotech and life sciences hub by venture capital investment:

$3.8 billion in VC raised in 20246 2,000 life sciences companies in the region.7 71,448+ direct employment jobs, average annual salaries exceeding $171,000.8
$54.1 billion in total life sciences economic output (2024)9 $1 billion+ in NIH grants to San Diego institutions in FY2024 (fourth nationally).10 $1.73 billion in UC San Diego grants and awards.11

The research anchors (UC San Diego, Scripps Research, Salk Institute, Sanford Burnham Prebys) produce the basic science from which commercial biotech is built. They attract international researchers, collaborators, and funding; generate the IP that pharmaceutical companies acquire; and sustain the relationships across which the next wave of investment flows.

San Diego's structural advantage is the proximity of world-class basic research to a deep commercial biotech pool, surrounded by CROs, contract manufacturers, specialized law and finance, and a public health research network anchored by the VA medical system. International companies acquire here partly for the IP, and partly because proximity to the research cluster is itself valuable, and acquisition is the most direct way to establish it.


The Research Foundation

Everything that follows in this case study begins here. The $20 billion in acquisitions, the Novartis greenfield, the seven-nation investment pattern: all of it traces back to four research institutions and the scientists they attract.

$1.73B UCSD Grants & Awards
8,134 International Students
4,100 Graduate Researchers
100+ Countries
UC San Diego The anchor institution

$1.73 billion in grants and awards in FY2024.11 8,134 international students (Fall 2024), including approximately 4,100 graduate researchers from more than 100 countries. These are not a tuition line item: they are the scientists who produce the research that attracts pharmaceutical licensing deals, discovery partnerships, and ultimately the acquisitions that define San Diego's international life sciences economy.

Those students are under active federal pressure. In April 2025, the federal government revoked F-1 visas for 36 UCSD students without explanation, all reversed by May 2025 following litigation, but the precedent was set.23 Nationally, new international enrollment fell 17 percent in Fall 2025; California faces a projected 15 percent decline representing more than $1 billion in lost tuition and living-expense revenue, before downstream research losses. The City's February 2026 Council resolution opposing ICE enforcement tactics and authorizing amicus briefs is, in economic terms, a signal that San Diego's governing institutions regard international scientists as a protected asset, not a political liability. For researchers with multiple international options, that signal is competitive, not symbolic.

Scripps Research #1 US stand-alone biomedical research institute (Nature Index, 2019). #1 globally for research influence on patents. Drug discovery division Calibr has contributed to 18 FDA-approved medicines.1213 The ReFRAME drug repurposing platform (Gates Foundation-supported) connects Calibr with dozens of US and international laboratories.14 These agreements often evolve into licensing deals and acquisitions of the companies Scripps scientists spin out.
Salk Institute Plant biology, neuroscience, cancer, aging, and immunity: areas precisely aligned with the therapeutic categories driving the most active international pharma M&A. Scientific relationships with European and Asian institutions feed the network through which San Diego's commercial pipeline is identified and developed.
Sanford Burnham Prebys Disease-relevant early targets and tool compounds that feed downstream drug discovery. SBP's Conrad Prebys Center for Chemical Genomics is one of the few US institutions providing open-access screening to academic and industry researchers globally: results that feed directly into commercial collaboration agreements.

The France Mission as Proof Point

The September 2025 France trade mission led by Mayor Gloria and Congressman Scott Peters produced three life sciences outcomes:15

🇫🇷
CNRS Research Agreements
France's CNRS, the world's largest public research organization by output, signed agreements to place researchers at UCSD and SDSU: the bilateral relationships through which future licensing deals and acquisitions originate.
🇫🇷
Eurobiomed-Biocom MOU
Formal linkage between France's Mediterranean life sciences cluster and Biocom California: institutional plumbing for company-to-company introductions across Montpellier/Marseille and San Diego.
🇫🇷
Marseille Sister City
The diplomatic and cultural framework beneath the scientific and commercial relationships: the layer that makes international collaboration sustainable over time.

Taken together, these represent the City's contribution to the research foundation: maintaining the relationship infrastructure through which San Diego stays globally connected, visible, and attractive to the researchers and capital that sustain the commercial pipeline.16


The Acquisition Pipeline

The Aggregate

7 Source Nations
12 Confirmed Transactions
$20B+ Confirmed Activity
~$4B/yr Acquisition Pace

International pharma and biotech companies acquired San Diego life sciences targets at a pace exceeding $4 billion per year across 2021-2026, from seven nations.15

Methodology: Upfront payments where disclosed; milestone-contingent amounts at announced ceiling. Nine acquisitions (~$22B) + three licensing/collaboration deals. The conservative "$20 billion+" figure excludes Bavarian Nordic/Emergent (~$270M, 2023) where SD-specific value could not be isolated. These are M&A transaction values, not capital deployed in San Diego. 96% of SD life sciences FDI is M&A; only 4% is greenfield.8

Post-acquisition employment outcomes vary significantly:

AcquirerDealPost-Acquisition Outcome
Bayer/Vividion$1.5B (2021)EXPANDED: 270 employees, new HQ and R&D center
Novartis/Avidity$12B (2026)Too early to assess; Novartis building $1.1B GBRC
Roche/Poseida$1.0B (2025)REDUCED: 52 employees laid off (~15%)
Sanofi/Inhibrx$1.7B (2024)Retained via spinoff (not foreign-owned)
Boehringer/Nerio$1.3B (2024)9 employees: IP purchase, not employment event
Novartis/Kate~$1.1B48 employees, absorbed into Novartis SD
Novartis/Regulus$800M (2025)~40 employees, absorbed into Novartis SD

Counter-data: Three foreign companies departed or reduced San Diego life sciences presence in 2024-2025: Takeda (324 jobs), Bavarian Nordic (48 jobs), Novartis TRD manufacturing (~100 jobs), totaling 472 jobs lost.21 Against 79,000 foreign-owned enterprise employees regionwide this is 0.6%, but it is real and discoverable.

International licensing and collaboration deals also brought significant upfront capital to San Diego in 2024:

What This Delivers

Seven Nations, Five Years Switzerland (Novartis, Roche), Germany (Bayer, Boehringer Ingelheim), France (Sanofi), Belgium (UCB), Japan (Kyowa Kirin, Takeda), Italy (Chiesi), and Sweden (Sobi). The international pharmaceutical community has repeatedly selected San Diego as a source of late-stage drug candidates.
The Flywheel Mechanism Institutions generate the basic science. Entrepreneurs and VCs form companies around it. Those companies advance candidates through development. International pharma buys the candidates because it cannot generate equivalent discovery output internally.
The Measurement Gap The last comprehensive FDI tracking study was published in 2020. This $20B+ synthesis exists because no institution was tracking the aggregate. A post-acquisition employment framework (Vividion expanded; Takeda departed) does not exist. Building that measurement infrastructure is the most immediate way to convert this research finding into an operational intelligence capability.
Avidity Biosciences: The $12 Billion Proof Point La Jolla, founded 2012. Acquired by Novartis, February 2026.

Avidity developed a platform technology for oligonucleotide delivery, getting RNA-based therapeutics into specific tissues, including muscle. Lead program: Duchenne Muscular Dystrophy. Novartis agreed to acquire Avidity for $12 billion in late 2024, completing the transaction in February 2026.2

This is the largest acquisition of a San Diego biotech company by a foreign buyer in the cluster's history, and the clearest statement of the international investment thesis: Novartis is not buying a product, it is buying a platform. It is paying $12 billion to apply Avidity's delivery technology across multiple future programs, because Avidity's San Diego team built something Novartis's internal R&D could not replicate.

The platform, not the product. That is San Diego's competitive advantage in the global pharmaceutical market, and it is built on the basic science infrastructure of the research institutions.


From Acquirer to Anchor

Novartis AG: Doubling Down on San Diego's Life Sciences

Novartis AG (Switzerland) has made more commitments to San Diego life sciences in 2024-2026 than any other international company in any sector in recent regional history.

$14B+ Total Committed
3 Acquisitions
$1.1B Greenfield Facility
2029 GBRC Operational Target
Values reflect upfront payments where disclosed. Kate and Regulus include milestone-contingent components.5

The Greenfield Decision

The $1.1 billion Novartis Global Biomedical Research Center, groundbreaking February 2026 with an operational target of 2029,3 is the most significant greenfield FDI commitment to San Diego life sciences in recent regional history.

This is not an acquisition. Novartis is building new research infrastructure here because it has concluded that physical presence in the cluster is worth $1.1 billion in capital and the complexity of running a major R&D center on a different continent from Basel.

The logic is explicit: San Diego's institutions, talent pool, and biotech ecosystem make it what Novartis has publicly described as one of the world's most productive drug discovery environments. Three acquisitions in two years (Kate, Regulus, Avidity) taught Novartis what San Diego produces; the $1.1 billion facility is the commitment to stay.

What Novartis's Presence Means for San Diego

The greenfield commitment changes the story in three ways:

It closes the extraction narrative. The standard critique is that acquisitions transfer locally developed IP to foreign companies. The Novartis Research Center inverts this: Novartis is bringing R&D capacity to San Diego, not just extracting IP. The scientists who work there will live here, train the next generation, and spin out the next generation of companies.
It signals to other international companies. AstraZeneca, Eli Lilly, Pfizer, Roche, and every major pharma company watching San Diego's acquisition pace will observe this decision. When the most acquisitive pharmaceutical company in San Diego builds its own research center here, it validates the thesis for every company still deciding whether to establish presence.
It creates a City-role opportunity. The facility's integration into San Diego's research community (joint appointments with UCSD and Scripps, participation in regional organizations, partnership with the City's engagement network) is the kind of sustained institutional relationship the City's infrastructure is designed to facilitate. The Swiss-American business community, the consular relationship, the potential for a Basel sister-city connection: these are City-level assets that compound on the commercial investment.

THE LIFE SCIENCES CLUSTER: POLICY IMPLICATIONS

The research-to-acquisition flywheel compounds at each stage.

1
Basic Science. Research institutions (UCSD, Scripps, Salk, SBP) generate the IP, funded by NIH ($1B+/year)10, international grants, and 8,134 international students.11
2
Company Formation. Entrepreneurs and VCs form companies around that science ($3.8B in VC, 2024).6
3
International Acquisition. International pharma acquires those companies because the science is irreplaceable: $20B+ since 2021, seven nations.1
4
Permanent Presence. Having acquired repeatedly, the same companies establish permanent presence: Novartis breaks ground on $1.1B facility, February 2026.3

The City's mandate is not managing contracts or replacing the market: it is sustaining the conditions that make the flywheel turn and ensuring San Diego captures the value it generates.

The Counter-Argument, and the Response

"Novartis and Bayer and Sanofi are buying San Diego biotech companies because the science is good. The City had nothing to do with it."

First, the science is produced by researchers who chose San Diego, a choice influenced by whether the city is internationally connected, welcoming, and active. The France mission produced CNRS researchers at UCSD. The ICE enforcement resolution signaled that San Diego's institutions will be protected. The City's engagement network seeds the next generation of research partnerships.

Second, the Novartis facility is not a response to science, it is a response to relationship. Three acquisitions taught Novartis what San Diego produces; the $1.1 billion facility is the conclusion that physical presence is worth the investment. The City's engagement function is the accelerant. It does not replace the science. It ensures the science is seen, understood, and valued by the decision-makers choosing where to place R&D investments.

The Data Gap, and the Opportunity

The last comprehensive FDI study for San Diego life sciences was published in 2020. This case study is the first systematic aggregation of the post-2020 period, identifying more than $20 billion in confirmed transactions5 no published report had previously assembled.

The gap is itself an argument. Cities that measure FDI can target it; cities that don't cannot prove it exists, or defend the budget lines that produce it. An annual or biennial FDI study, commissioned in partnership with WTCSD and the Regional EDC, would pay for itself in its first budget cycle.


GROWTH VECTORS AND RISK SIGNALS

Growth Vectors

Novartis GBRC as anchor for a second wave of European pharmaceutical presence.
Novartis's $1.1 billion Global Biomedical Research Center, groundbreaking February 2026 with an operational target of 2029, is the first greenfield pharmaceutical R&D facility in San Diego's history. The strategic question is whether it triggers a second wave: AstraZeneca, Roche, and Eli Lilly all have active San Diego acquisition histories and no comparable permanent research presence. Novartis's public framing, "the world's most productive drug discovery environment," is a signal that will be read by every pharmaceutical corporate development office in Basel, London, and Tokyo. If a second European pharma follows Novartis to greenfield within 36 months, it validates a new category of San Diego FDI that does not yet exist at scale.17
Post-acquisition employment compounding: the Vividion model.
Bayer acquired Vividion Therapeutics for $1.5 billion in 2021. By 2025, Vividion had expanded to 270 employees in a new San Diego headquarters and R&D center, the strongest proof point that M&A can produce employment growth, not just transaction headlines. If this pattern holds across the Novartis portfolio (Kate, Regulus, Avidity), the cumulative post-acquisition employment effect could exceed 1,000 San Diego positions within five years. The Vividion model is the answer to the extraction narrative, but only if it is tracked, measured, and replicated.18
CaliBaja research consortium as a cross-border life sciences asset.
The CaliBaja Higher Education Consortium (December 2025) linking UCSD, SDSU, and Baja California institutions creates a binational research framework with direct relevance to clinical trial enrollment, manufacturing cost arbitrage, and bilingual workforce development. The pharma companies acquiring San Diego biotech operate globally; a research cluster that spans the US-Mexico border is a differentiator no other US life sciences hub can offer.19
France CNRS connections as a model for bilateral research pipeline development.
The September 2025 France trade mission produced CNRS researcher placements at UCSD and SDSU, plus the Eurobiomed-Biocom MOU. France is the world's fourth-largest pharmaceutical market; CNRS is the world's largest public research organization by output. If these placements generate co-authored papers, joint grant applications, or licensing leads within 24 months, the France mission becomes the template for replicating bilateral research pipelines with other pharmaceutical nations: Germany (Max Planck), Japan (RIKEN), Switzerland (ETH/EPFL).20

Risk Signals

Post-acquisition employment attrition is real and accelerating.
Three foreign companies reduced or closed San Diego life sciences operations in 2024-2025: Takeda (324 jobs), Bavarian Nordic (48 jobs), Novartis TRD manufacturing (approximately 100 jobs), totaling 472 jobs lost. Against 79,000 foreign-owned enterprise employees regionwide, this is 0.6%, but it establishes that M&A-driven FDI carries departure risk. No institution currently tracks post-acquisition employment outcomes in San Diego life sciences. Without tracking, the City cannot distinguish between acquisitions that produce Vividion-style expansion and acquisitions that produce Takeda-style departure, and cannot intervene before the decision is made.21
M&A cycle dependency: what happens in a pharma acquisition drought?
San Diego's international life sciences FDI is 96% M&A-driven. The $20B+ aggregate since 2021 occurred during one of the most active global pharma M&A cycles in history. If global pharmaceutical M&A contracts (due to rising interest rates, regulatory scrutiny, or a pipeline drought) San Diego's FDI inflow contracts with it. The City has no greenfield FDI attraction strategy for life sciences (Novartis GBRC is company-initiated, not City-attracted). Diversifying from pure M&A dependency toward active greenfield recruitment is a structural resilience question, not an immediate crisis.22
International student pipeline under sustained federal pressure.
The April 2025 visa revocations (36 UCSD students, all reversed) and the national 17 percent decline in new international student enrollment are leading indicators. San Diego's life sciences pipeline begins in laboratories staffed by international graduate researchers. If the federal pressure continues and international enrollment declines further, the research output that attracts pharmaceutical acquisition interest will decline on a 5-7 year lag: long enough to be invisible in current metrics, short enough to be irreversible once it manifests.23

WHAT OTHER CITIES HAVE DONE

Boston / Cambridge, Massachusetts

State-Level Life Sciences Authority ($2.1B cumulative) Massachusetts Life Sciences Center (MLSC), established 2008: $1B initial authorization, reauthorized twice ($623M in 2018, $500M in 2023). Quasi-public authority deploying tax incentives, capital grants, workforce training, and direct investment in research facilities.
Zoning as Industrial Policy (Kendall Square) Cambridge's 2013 rezoning permitted purpose-built lab space at density, enabling 6+ million square feet now housing Moderna, Novartis US headquarters, Sanofi, Pfizer, and hundreds of startups. No cash incentives: zoning alone made it legal and efficient to build what life sciences companies need.

San Diego has no comparable state authority and has not used municipal zoning as a deliberate cluster tool. The Torrey Pines / UTC corridor evolved organically; it was not zoned for life sciences the way Kendall Square was.

Raleigh-Durham / Research Triangle, North Carolina

Performance-Based FDI Attraction ($9.1B since 2020) JDIG program: discretionary grants tied to job creation and capital investment, verified annually, with clawback for non-performance. NCBiotech has deployed $187M in grants since 1984. NC BioNetwork provides workforce training through 58 community colleges.
🇩🇰
Novo Nordisk$4.1B campus, 4,600 jobs
$15.8M JDIG over 12 years. North Carolina's largest single FDI project.
🇯🇵
FUJIFILM Diosynth$3.2B facility, 765 jobs
$30M JDIG. $200,000+ average salary.

The structural difference: North Carolina attracts greenfield manufacturing through transparent performance incentives. San Diego's FDI arrives through acquisition of companies that already exist here. Both models work, but San Diego has no mechanism to attract the greenfield investment that produces thousands of jobs at sites the City can influence.

Basel, Switzerland

Municipal-Pharma Partnership Canton of Basel-Stadt passed the Location Promotion Act in 2023 (63.2% referendum), authorizing CHF 150-500 million annually from a higher tax bracket on large pharma, reinvested into innovation infrastructure, workforce, and quality-of-life programs.
Open-Integration Campus Model The Novartis Campus in Basel: startups, research institutes, and university programs operate alongside Novartis researchers. The campus as ecosystem node, not walled compound.
BioValley: Trinational Cluster Governance Spanning Basel, Alsace (France), and Baden-Württemberg (Germany): 800+ companies, 1,000+ research groups, coordinated across three jurisdictions in a way no single city could have built alone.

San Diego's relationship with Novartis is entering a new phase. The Basel model suggests the most productive municipal response is not passive gratitude but active partnership: creating the conditions that make Novartis's investment compound, the way Basel has for decades.


BUILDING THE ENGAGEMENT FOUNDATION

The evidence above is built from public sources. What it cannot capture is the perspective of the people closest to these decisions, and the institutional knowledge that determines which models translate and which do not. The questions below are designed to start that conversation.

What the Research Establishes vs. What Remains Unknown

Stakeholder Questions

What is the City doing? How aware is Council of the $20B+ life sciences FDI figure? Do acquired companies interact with the City post-acquisition? Do UCSD, Scripps, and Salk see the City as relevant to their international partnerships?
What should the City be doing? Should the City invest in life sciences-specific zoning (Kendall Square model)? What would post-acquisition companies value: workforce programs, housing support, permitting acceleration? Should there be a formal research institution liaison?
What should the City not do? Where does life sciences engagement cross into state or federal jurisdiction? Do pharma companies want municipal government involved in their acquisition strategy? Is there risk that City engagement creates complications for institutions navigating federal visa policy?
What could the City do quickly? Could Council pass a resolution establishing life sciences as a priority international economic sector? Would acquired-company site leaders participate in a City-convened roundtable on post-acquisition retention? Could the City fund a biennial FDI tracking study?
