Business Escrow for San Diego Biotech Acquisitions
San Diego is home to more than 1,300 life sciences companies, and the deal flow in Torrey Pines and Sorrento Valley never slows down. Business escrow keeps biotech acquisitions moving when the money, the milestones, and the equipment all need to change hands on different timelines.
If you work in biotech in San Diego, you already know the corridor. Torrey Pines, Sorrento Valley, Sorrento Mesa, La Jolla, Carmel Valley. This is the second largest life sciences cluster in the country, and the deal activity here is constant. Neurocrine Biosciences bought Soleno Therapeutics for $2.9 billion in May 2026. Pfizer sold its Torrey Pines research campus to BioMed Realty in 2024. Companies form, get funded, get acquired, spin out, and start all over again.
Every one of those transitions moves money between parties who do not fully trust each other yet. That is where business escrow comes in. At Secured Trust Escrow, we hold the funds, verify the closing conditions, and release payments when each milestone is actually met. We are not residential escrow. We handle the business side: acquisitions, earnouts, equipment transfers, and everything that makes a biotech deal more complicated than a standard closing.
Why Biotech Acquisitions Are Different
A biotech acquisition almost never closes with a single wire. Buyers pay a portion at closing, then hold back money against milestones like FDA submissions, trial data readouts, or revenue targets. Lab equipment and specialized buildouts transfer separately from the company itself. Leases on lab space need landlord consent. IP assignments have to be recorded before anyone feels safe.
Escrow is the hub that connects all of it. The money sits with a neutral third party while each piece catches up. Here is what a typical structure looks like:
| Escrow Component | What It Covers | When It Releases |
|---|---|---|
| Closing payment | Purchase price due at signing | When closing conditions are met |
| Milestone holdback | Earnouts tied to data or revenue | When each milestone is verified |
| Equipment funds | Lab equipment and buildout assets | On delivery and buyer inspection |
| Indemnity reserve | Post closing claims and disputes | After the claim window ends |
Earnouts Are Where Deals Get Tense
Most biotech acquisitions include an earnout because buyers refuse to pay full price upfront for revenue that might not materialize. The seller takes less cash at closing in exchange for future payments if the science performs. The tension shows up eighteen months later when both sides disagree on whether the milestone was hit.
A well drafted escrow instruction prevents that fight. The release conditions are written down before money moves, and the escrow officer follows the document, not the mood of either party. We wrote a full breakdown of how these structures work in our guide to earnout escrow for California tech acquisitions, and most of it applies directly to life sciences deals.
“Biotech buyers do not pay for hope, and sellers do not hand over a company for promises. Escrow lets both sides commit real money while everyone waits for the data to prove itself.”

The Deal Flow We See Locally
The bulk of San Diego biotech deal flow is not the nine figure headline acquisitions. It is mid cap companies buying service providers, platform companies absorbing startups out of UC San Diego and the research institutes, and retiring founders selling their instrumentation or CRO businesses to younger operators. Those deals are still worth millions, and the buyers and sellers still need a neutral party holding the money.
The most common mistake we see is treating escrow as a formality. Buyers and sellers agree on price, sign the paperwork, and then discover their release instructions are vague. Good escrow starts before the purchase agreement is signed, with clear milestones, clear verification steps, and clear deadlines.
