Section 1
Market Overview: Volume, Value, and Composition
The biopharma deal market expanded significantly through 2024, with annual transaction volume rising from 269 deals in 2020 to 535 in 2024 — a compound annual growth rate of 18.7%. Total disclosed deal value peaked in 2020 at $1.03 trillion (n=269, average $4.0B per deal), reflecting several mega-transactions, before normalizing to $814B–$900B annually through 2022–2023. The 2024 cycle saw a resurgence: $1.14 trillion across 535 deals, though the average deal size of $2.3B was 42% below the 2020 peak, indicating a structural shift toward higher-volume, lower-value transactions.
Through the first half of 2026, deal velocity has remained elevated. Q1 recorded 33 transactions and Q2 added 38 more, putting the year on pace for approximately 760–800 deals — which would be the highest annual count on record. Average deal size continues to compress, now at $1.9B, reflecting buyers distributing capital across more transactions with tighter risk-sharing structures rather than concentrating in transformative acquisitions.

Section 2
Risk-Adjusted Phase Economics: When to Exit
The conventional wisdom in biotech dealmaking is straightforward: more clinical data equals a higher exit price. Phase 3 median upfront ($678M) is 2.3x Phase 2 ($300M). On paper, holding to Phase 3 is the clear winner.
But the paper calculation ignores three factors that fundamentally alter the math: Phase 3 trial costs ($200–$500M), timeline (2–3 years), and failure rates (40–50%). When you risk-adjust the Phase 3 upside and subtract the capital required to get there, Phase 2 proof-of-concept emerges as the stronger exit for most single-asset biotechs.
Exhibit 2A
Decision Tree: Sell at Phase 2 vs. Hold to Phase 3
Visual representation of the risk-adjusted exit decision. Follow the branches to see expected values at each node.
Trial cost: $350M midpoint ($200–$500M range). Salvage: $35M midpoint ($20–$50M). Phase 3 success: 55%. Upfronts are median values from Ambrosia Ventures deal database (1,600+ transactions). Individual assets may deviate significantly from medians.
Key Insight
The expected value of selling at Phase 2 ($300M) is nearly 8x the expected value of holding to Phase 3 ($38M) when trial costs and failure rates are factored in. For single-asset biotechs without the capital reserves to absorb a Phase 3 failure, the risk-adjusted case for exiting at Phase 2 is overwhelming. The founders who capture the most value are not the ones who hold longest — they are the ones who recognize when their risk-adjusted value has peaked.
Exhibit 2B
Phase 2 → Phase 3 Multiplier by Therapeutic Area
All therapeutic areas show a 2.1x–3.5x multiplier from Phase 2 to Phase 3 upfront. Metabolic commands the highest multiplier (3.5x) but also carries the highest absolute Phase 3 trial costs ($300–$600M).
| Therapeutic Area | Ph2 Median Upfront | Ph3 Median Upfront | Ph2→Ph3 Multiple | Ph3 Trial Cost |
|---|---|---|---|---|
| Metabolic/Obesity | $150M | $400M | 3.5x | $300–600M |
| Immunology | $120M | $300M | 2.6x | $200–400M |
| Neurology | $75M | $180M | 2.8x | $250–500M |

The risk-adjusted calculus varies by therapeutic area. Metabolic assets show the highest Phase 2→3 multiplier (3.5x) but also carry the highest Phase 3 trial costs ($300–$600M for large-scale cardiovascular outcomes trials). Rare disease assets have the lowest multiplier (2.3x) but substantially lower trial costs ($100–$250M) and higher Phase 3 success rates due to smaller, more defined patient populations and regulatory pathway advantages.
BD teams should map their specific asset's risk-adjusted value curve before entering exit discussions. The interactive calculator below models this across all therapeutic areas and modalities.

Section 3
Therapeutic Area Economics at Phase 2
Therapeutic area drives valuation more than any other single variable in biopharma dealmaking. Phase 2 median upfronts range from $40M (women's health) to $150M (metabolic/obesity) — a 3.8x spread. This is not noise: it reflects genuine differences in addressable market size, competitive intensity, and commercial model validation. When benchmarking your asset, start with the therapeutic area median, then layer in modality premiums and phase-specific adjustments.

Phase 2 Deal Economics by Therapeutic Area
| Therapeutic Area | Ph2 Median Upfront | Ph2 Median TDV | Upfront/TDV | Ph2→Ph3 Multiple |

The heatmap reveals a critical insight: therapeutic area premiums compound at later stages. The spread between metabolic and women's health is 3.8x at Phase 2 ($150M vs $40M) but widens to 4.6x at the approved stage ($1.2B vs $260M). BD teams with multi-indication assets should time their exit based on the indication with the highest TA premium, not necessarily the most clinically advanced program.
Section 4
Modality Premiums and Market Cycles
Modality premiums are not static. They follow market cycles driven by clinical validation events, platform acquisitions, and supply dynamics. Understanding where a modality sits in its cycle is as important as understanding the premium itself. Buying at peak enthusiasm overpays; licensing at cycle trough undervalues genuine innovation.
Exhibit 4A
ADC Market Cycle: Deal Volume and Total Value (2019–2025)
The 2023 Pfizer/Seagen acquisition ($43B) created a once-in-a-generation peak. Premiums have since normalized from ~1.70x to 1.45x as the market shifts from platform acquisitions to single-asset licensing.
| Year | ADC Deals | Median TDV | Total Value | Cycle Phase |
|---|---|---|---|---|
| 2019 | 17 | $1.3B | $46.2B | Early growth |
| 2020 | 20 | $2.7B | $136.8B | Expansion |

Key Insight
Radiopharmaceuticals are in peak-cycle territory. Novartis Pluvicto validation (>$1B annual sales within 18 months), constrained isotope supply, and platform acquisitions by BMS, Lilly, and AstraZeneca have driven aggressive bidding. ADCs are normalizing — the shift from platform to single-asset deals means premiums now require target differentiation, payload novelty, and Phase 2 data quality. Bispecifics are stable with validated commercial models (teclistamab, epcoritamab, glofitamab). PROTAC/degraders and mRNA are in early-growth phase with rising interest but fewer large data points.
Section 5
Royalty Rate Benchmarks
Royalty rates are the most opaque element of biopharma deal economics. Unlike upfront payments and total deal values, which are frequently disclosed in press releases, royalty rates are buried in SEC filings and often redacted. This section presents benchmarks derived from deals where royalty terms were disclosed, covering the full spectrum from discovery to approved assets.
Exhibit 5A
Royalty Rates by Development Phase
Royalties escalate 2–5 percentage points per development phase. The Phase 2 to Phase 3 step-up (11.5% → 16%) is the largest single-phase increase in royalty terms, mirroring the upfront payment pattern. At the approved stage, royalties of 18–25% are standard, reflecting the near-elimination of clinical risk.
Exhibit 5B
Phase 2 Royalty Rates by Modality
| Modality | Low | Median | High | NPV per 1%pt ($2B peak sales) |
|---|---|---|---|---|
| ADC | 10% | 14% | 18% | $30–80M |
| Radiopharmaceutical | 10% | 13.5% | 17% | $30–80M |
| Bispecific Antibody | 9% | 12.5% | 16% | $30–80M |
| mRNA Therapeutics | 9% | 12.5% | 16% | $30–80M |
| Small Molecule | 8% | 11.5% | 15% | $30–80M |
| CAR-T Cell Therapy | 8% | 11% | 14% | $30–80M |
| Gene Therapy | 7% | 10% | 13% | $30–80M |
NPV per 1 percentage point based on $2B peak sales, 10-year commercial life, 12% discount rate. A single percentage point of royalty represents $30–80M in NPV for a blockbuster asset. Source: Ambrosia Ventures deal database.
Key Insight
Over 70% of licensing deals now employ tiered royalty structures with escalation clauses tied to sales thresholds — for example, 10% up to $1B, 12% to $3B, 15% above. This represents a structural shift from flat-rate royalties and creates alignment between licensor and licensee: both parties benefit more as commercial performance exceeds expectations. A single percentage point of royalty represents $30–80M in net present value for a $2B peak-sales asset — making royalty negotiation one of the highest-leverage elements of deal structuring.
Section 6
Deal Structure Evolution
The biopharma deal market is undergoing a structural transformation. Three simultaneous shifts are reshaping how transactions are structured: rising upfront percentages, growing option deal share, and the emergence of a bimodal deal-size distribution.
Exhibit 6A
Upfront as Percentage of Total Deal Value (2020–2026)
Upfront share has risen from 20.3% in 2021 to 29.0% in 2026 YTD, reflecting sellers' growing negotiating power and tighter biotech capital markets.
Exhibit 6B
Deal Structure Composition
| Structure | Count | Share | Avg Upfront % of TDV | Trend |
|---|---|---|---|---|
| Licensing | ~31% | Dominant | 15–20% | Stable |
| Acquisition | ~23% | Second | 100% | Stable |
| Collaboration | ~20% | Growing | 22% | Stable |
| Co-Development | ~13% | Established | 10–14% | Stable |
| Option | ~13% | Fastest-growing | 5–10% | 8% → 18% (2020→2025) |
Source: Ambrosia Ventures deal database. Shares based on cumulative deal count (2020-2026). Option deal growth from 8% in 2020 to 18% in 2025 is the most significant structural shift in the period.
The option deal surge (8% → 18%) deserves attention. For buyers, options offer lower upfront commitment with the right to acquire after seeing data — a put option on clinical risk. For sellers, options provide non-dilutive funding with the potential for full-value transactions at exercise. The risk is asymmetric: if data disappoints, the option lapses and the seller retains the asset but loses the partner. If data exceeds expectations, the option exercise price may undervalue the asset relative to a competitive auction.
Exhibit 6C
Bimodal Deal Distribution
The mid-market ($200M–$800M) is thinning as deal volume concentrates at the extremes: mega-deals exceeding $5B and discovery-stage transactions under $200M.

Section 8
Q2 2026 Market Themes
Four structural forces are reshaping biopharma dealmaking in mid-2026. These themes build on Q1 trends but represent distinct market dynamics that will define the second-half deal environment. BD teams should evaluate their portfolio positioning against each theme.
Theme 1
Metabolic/Obesity Assets Are Repricing the Entire Deal Market
Metabolic/obesity now commands the highest Phase 2 total deal values ($2.0B median) of any therapeutic area — surpassing oncology for the first time in our dataset. The 3.5x Phase 2→Phase 3 multiplier is the highest across all TAs, reflecting outsized buyer conviction in assets with GLP-1 commercial validation and addressable markets exceeding $100B annually.
The repricing extends beyond GLP-1 agonists. Oral GLP-1s, GIPR/GLP-1R dual agonists, and next-generation delivery platforms are all commanding premiums previously reserved for late-stage validated oncology assets. The Novo Nordisk/Catalent acquisition ($16.5B) illustrates the scale of capital deployment in this space — a manufacturing infrastructure deal valued at multiples historically reserved for pipeline acquisitions.
Key Insight
Metabolic/obesity has fundamentally altered the deal hierarchy. For the first time, a non-oncology therapeutic area commands the highest Phase 2 valuations. BD teams with metabolic assets should benchmark against metabolic-specific medians, not cross-TA averages — cross-TA benchmarking undervalues metabolic assets by 40–60%.
Theme 2
The Radiopharmaceutical Land Grab
Radiopharmaceutical deal premiums surged +1,408% in upfront valuations over the last two years, displacing ADCs as the highest-premium oncology modality. Three forces converge: Novartis Pluvicto's commercial validation (exceeding $1B in annual sales within 18 months of launch), constrained isotope supply (Actinium-225, Lutetium-177), and aggressive platform acquisitions by BMS, Lilly, and AstraZeneca.
The supply constraint is structural: Actinium-225 production is limited to a handful of global facilities, and new capacity takes 3–5 years to build. This creates a land-grab dynamic where acquirers are paying premiums not just for the molecule but for access to isotope supply chains. The remaining independent radiopharmaceutical companies with validated targets and manufacturing partnerships are trading at multiples that reflect scarcity, not just clinical merit.
Key Insight
Radiopharmaceutical premiums are supply-driven, not just science-driven. The 1.60x multiplier may compress once new isotope production comes online (2028–2029), but near-term scarcity ensures elevated valuations through 2027. BD teams with radiopharmaceutical assets have a narrowing window to capture peak-cycle premiums.
Theme 3
China-to-West Licensing: From Emerging Trend to Market Structure
Chinese biotech out-licensing has crossed the threshold from emerging trend to permanent market structure. Total deal value from Chinese biotechs reached $136B in 2025 (+162% YoY) and $52B in the first eight weeks of 2026 alone — matching the entire 2024 total in under two months. Average deal size is $1.3B (+76% vs 2025), confirming this is not cost arbitrage but genuine innovation premium.
The PD-1/VEGF bispecific class illustrates the scale: Pfizer licensed from 3SBio, BMS partnered with BioNTech-Biotheus, and Merck acquired rights from LaNova — three separate Western pharma companies licensing the same drug class from three different Chinese biotechs. Chinese biotechs now account for approximately 90% of global ADC out-licensing. Key transactions: AstraZeneca/CSPC ($18.5B), GSK/Hengrui ($12B+), BMS/BioNTech-Biotheus ($11.1B), Pfizer/3SBio ($6B).
Key Insight
Western pharmaceutical pipelines are structurally thin in ADCs and bispecific antibodies. Chinese biotechs built deep capability in exactly those modalities. The geography of biopharma innovation has permanently shifted. Six of the top 10 pharma companies have licensed from Chinese biotechs in the last 12 months. Non-Chinese biotechs developing ADCs and bispecifics are now competing against a price baseline set by Chinese out-licensing economics.
Theme 4
Phase 2 Proof-of-Concept as the Optimal Exit Window
A growing number of high-profile acquisitions are occurring at Phase 2 rather than Phase 3 — and the data supports this as the rational strategy. Merck's $10.8B acquisition of Prometheus Biosciences (anti-TL1A, ulcerative colitis) on Phase 2 data alone is the most visible example, but the pattern extends across therapeutic areas.
The risk-adjusted math favors Phase 2 exits (see Section 2). When Phase 3 costs ($200–$500M), timelines (2–3 years), and failure rates (40–50%) are factored in, the expected value of selling at Phase 2 exceeds the expected value of holding to Phase 3 for most single-asset biotechs. This is not a new phenomenon — it has always been true in the numbers — but founder and board awareness of this dynamic is increasing, driven by high-profile Phase 3 failures at companies that could have exited at Phase 2.
The practical implication: biotechs should build their capital strategy around reaching Phase 2 proof-of-concept with 18+ months of runway. The $30M bridge round to reach PoC may be the highest-ROI capital a founder ever raises. The alternative — running out of cash six months before a data readout that could have changed the trajectory — is the most expensive mistake in biotech, and it happens more often than any board would admit.
Key Insight
The Phase 3 trial Prometheus never ran was worth nothing. The Phase 2 data they already had was worth $10.8 billion. BD teams should model risk-adjusted exit values at every clinical milestone, not just at the end of the development timeline. The founders who capture the most value are not the ones who hold longest — they are the ones who recognize when their risk-adjusted value has peaked.
Section 9
Territory and Cross-Border Dynamics
Territory-split structures continued to grow as biotechs retained US commercialization rights while licensing ex-US. The median ex-US deal carries a 30–40% discount to global rights, but for biotechs with US commercial infrastructure, this approach maximizes total value realization. Japan commands a 15–25% premium on a per-market basis versus comparable European territories, driven by regulatory predictability and favorable pricing.
China standalone value declined to 5–8% of global (from a 10–15% peak) following NRDL pricing reforms and Volume-Based Procurement pressures. The exception is metabolic assets, where China premiums of 15–20% above baseline ex-US value have emerged, driven by 180 million adults with obesity and rapid GLP-1 manufacturing buildout.
Exhibit 9
Territory Value as % of Global Deal Economics
US-only deals capture 65–70% of global value. Japan maintains a per-market premium. China standalone has declined to 5–8% except for metabolic assets.
Greater APAC (Japan + China + SEA + ANZ) accounts for 20–30% of global biopharma deal value, with Japan alone representing 12–18%. Chinese deal structures show distinctive characteristics: upfronts represent 10–20% of total deal value (versus 20–30% for Japan), milestones are weighted heavily at 50–60% of total value, and deal timelines of 6–12 months reflect regulatory complexity. Growing use of escrow arrangements for milestones exceeding $50M signals increasing deal sophistication in the region. See our Europe licensing benchmarks and APAC territory analysis for detailed regional data.

Quarter-over-Quarter: Q1 vs Q2 2026
A side-by-side comparison of key deal metrics between Q1 and Q2 2026. Arrows indicate directional change; significance should be interpreted in context of deal volume and mix.
Q/Q comparisons are based on cumulative deal database metrics. Many medians remain stable quarter-to-quarter due to the growing corpus size; meaningful shifts typically emerge over 2–4 quarters. This dashboard will track directional changes across all metrics in future reports.
Deal Anatomy
Merck / Prometheus Biosciences: $10.8B on Phase 2 Data
A line-by-line dissection of the deal that defines the Phase 2 exit thesis, benchmarked against the Ambrosia Ventures deal database.
The Asset
PRA023 (now duvakitug), a first-in-class anti-TL1A monoclonal antibody for inflammatory bowel disease (ulcerative colitis and Crohn's disease). TL1A is a TNF superfamily cytokine implicated in mucosal inflammation — a novel mechanism distinct from existing anti-TNF and anti-IL-23 therapies.
The Data
Phase 2 results in ulcerative colitis showed statistically significant clinical remission rates versus placebo, with a differentiated safety profile. The data was presented prior to the acquisition announcement. No Phase 3 data existed at the time of the deal.
How It Benchmarks
| Metric | Prometheus Deal | Immunology Ph2 Median | Premium |
|---|---|---|---|
| Acquisition Price | $10.8B | $1.5B (TDV) | 7.2x |
| Upfront (100% at close) | $10.8B | $120M | 90x |
| Stage | Phase 2 | Phase 2 | — |
| Mechanism | First-in-class | Various | — |
| Indication | UC / Crohn's | Various | — |
| Time: IPO to acquisition | ~22 months | N/A | — |
Why This Deal Matters
Prometheus traded at 7.2x the immunology Phase 2 median TDV and 90x the median upfront. This is not simply a premium — it is a different category of transaction. Three factors drove the multiple: (1) first-in-class mechanism with no direct competitor in TL1A, (2) IBD market exceeding $25B annually with unmet need for non-TNF mechanisms, and (3) clean Phase 2 efficacy data that de-risked the biology, if not the pivotal trial. The deal proves that exceptional Phase 2 data in a validated commercial market can command acquisition economics typically reserved for Phase 3 or approved assets. BD teams should not benchmark exceptional assets against median deal economics — they should benchmark against the acquisition premiums that first-in-class mechanisms with blockbuster market potential command.
Forward Look
H2 2026 Outlook: What the Data Says Is Coming
Four predictions for the second half of 2026, derived from deal flow patterns, modality cycles, and structural shifts in the 1,600+ transaction dataset.
Radiopharmaceutical premiums will peak and plateau
The 1.60x multiplier is supply-driven and supply is being built. BMS, Lilly, and AstraZeneca have all made platform acquisitions. The remaining independent radiopharmaceutical companies will face either acquisition offers at peak premiums or a gradual compression as isotope capacity expands (2028-2029 timeline). H2 2026 is the window for maximum value capture.

Metabolic deal volume will accelerate into 2027
Oral GLP-1s, dual agonists, and next-gen delivery platforms are in Phase 2 across 15+ companies. The $100B+ addressable market and 3.5x Phase 2→3 multiplier will attract capital and buyers at a pace that outstrips current deal flow. Expect 3-5 metabolic transactions exceeding $5B TDV before year-end.

Watch for: Oral GLP-1 Phase 2 readouts, amylin/GLP-1 combinations
Option deal structures will cross 20% share
The option deal trajectory (8% → 18% over 5 years) shows no signs of slowing. Buyers prefer the structure in high-uncertainty therapeutic areas (neurology, CNS) where Phase 2 data is directional but not definitive. Sellers accept options when the alternative is no deal or a heavily milestone-weighted license. The 20% threshold will likely be crossed by Q4 2026.
Leading Indicator
Watch for: Option exercise decisions on Phase 2 assets signed in 2024-2025
AI-discovered molecules will generate $10B+ in licensing value
The Lilly/Insilico deal ($2.75B) validated AI-originated deal flow at institutional scale. With 28 AI-developed drugs in pipeline and nearly half at clinical stage, the next 6 months will see 3-5 additional deals. Cumulative 2026 AI-originated deal value will exceed $10B, concentrated in oncology small molecules and metabolic targets where AI-driven structure prediction has the strongest track record.
Leading Indicator
Watch for: Phase 2 readouts from Recursion, Relay, Exscientia pipeline assets
These predictions are derived from deal flow patterns and structural analysis, not clinical trial outcomes. Accuracy depends on continuation of current market dynamics. Ambrosia Ventures will track these predictions in the Q3 2026 report and score them against actual deal activity.

Appendix
Methodology and Limitations
Sample Selection
This report analyzes 1,600+ biopharma transactions executed between January 1, 2020 and June 30, 2026. Transactions are sourced from SEC 8-K filings, FTC premerger notification filings, company press releases, investor presentations, and ClinicalTrials.gov. Each transaction is verified against at least one primary source before inclusion. New deals are ingested weekly (approximately 38 per week) via automated SEC EDGAR monitoring plus manual verification.
Survivorship Bias
This dataset includes only deals with publicly disclosed financial terms. Transactions with undisclosed terms are excluded, which may introduce upward bias in reported medians. Additionally, failed or terminated deals are underrepresented. Readers should treat reported medians as reflective of the disclosed deal universe, not the complete market.
Statistical Methodology
Medians are used throughout to minimize distortion from mega-deals. Sample sizes (n) are reported for every cohort. Interquartile ranges (P25–P75) are reported where sample sizes permit meaningful dispersion analysis. Cohorts with n<10 should be treated as directional only. Cohorts with n>100 produce highly stable estimates.
Risk-Adjusted Calculations
The Phase 2 vs Phase 3 risk-adjusted analysis (Section 2) uses median values from the deal database, industry-standard Phase 3 failure rates (40–50%), and estimated trial costs ($200–$500M) derived from published literature and company disclosures. Individual asset risk profiles may vary significantly from these medians. The analysis is intended as a framework for thinking about exit timing, not as asset-specific financial advice.
Royalty Rate Data
Royalty rates are derived from deals where terms were publicly disclosed in SEC filings or press releases. This represents a subset of total deals, as royalty rates are frequently redacted. Reported ranges should be treated as indicative of disclosed-deal economics, which may skew toward higher-profile transactions.
Therapeutic Area Classification
Deals are classified into 12 therapeutic areas based on the primary indication of the lead asset. Multi-indication assets are assigned to the therapeutic area of the most advanced indication. Where a deal covers multiple assets, the deal is counted once under the primary asset's classification.
Update Frequency
The full dataset is refreshed continuously; this quarterly report provides point-in-time narrative analysis as of July 15, 2026. The interactive Solidus platform reflects real-time data. This page revalidates every 6 hours via ISR.
Important Caveat
Sample sizes vary significantly across therapeutic area and modality cohorts. Oncology (n=257 at Phase 2) provides high-confidence benchmarks. Smaller cohorts — metabolic (n=11), hematology (n=5) — should be interpreted as directional. We recommend oncology benchmarks as the primary reference and TA-specific adjustments as secondary overlays. Modality cycle analysis reflects historical patterns and should not be extrapolated as predictive.

Frequently Asked Questions
What data sources does this report use?
The report analyzes 1,600+ verified biopharma transactions (2020-2026). Sources include SEC 8-K filings, FTC premerger filings, company press releases, and ClinicalTrials.gov. New transactions are ingested weekly (~38/week) via automated monitoring and verified before inclusion.
How should I interpret small sample sizes?
Cohorts with n>100 (e.g., oncology Phase 2, n=257) produce stable medians. Cohorts with n<20 are directional — the median is real but the confidence interval is wide. Cohorts with n<10 should be treated as indicative only. We report sample sizes and P25-P75 ranges throughout.
Why is Phase 2 the risk-adjusted optimal exit?
Phase 3 median upfront ($678M) is 2.3x Phase 2 ($300M), but Phase 3 costs $200-500M, takes 2-3 years, and fails 40-50% of the time. Risk-adjusting the Phase 3 upside and subtracting trial costs yields an expected value lower than the certain Phase 2 exit. See Section 2 for the full calculation.
What are current royalty rate benchmarks?
Royalty rates range from 3-7% at discovery to 18-25% for approved assets. At Phase 2, ADCs command the highest median (14%), followed by radiopharmaceuticals (13.5%) and bispecifics (12.5%). Over 70% of deals now use tiered royalty structures. See Section 5 for full analysis.
Why are upfront percentages rising?
Average upfront as % of TDV increased from 20.3% (2021) to 29.0% (2026 YTD). Three factors: tighter biotech capital markets requiring larger upfronts, competitive intensity among buyers for differentiated assets, and seller sophistication in negotiating upfront-weighted structures.
How have ADC premiums changed?
ADC premiums peaked at ~1.70x during the 2023 Pfizer/Seagen cycle ($371.8B total value). They have since normalized to 1.45x as the market shifts from platform acquisitions to single-asset licensing. Radiopharmaceuticals have displaced ADCs as the highest-premium oncology modality at 1.60x.
What is the conditional value trend?
Conditional value (milestone share of TDV) declined from 79.7% (2021) to 71.0% (2026 YTD). More value is shifting to upfront payments. Milestones are increasingly tied to high-probability events rather than diffuse triggers.
