What Happened
BillionToOne, Inc. announced on June 23, 2026 that it entered into a lease with Whipple Road Portfolio, LLC for approximately 62,659 square feet of office and laboratory space at 3260 Whipple Road, Union City, CA. The lease is expected to commence on or about August 1, 2027 after tenant improvements, has an initial 12‑year term with a 10‑year extension option, and will more than triple the company’s oncology‑dedicated lab space while increasing total facility space by ~16%. The lease creates a material financial obligation for the company.

Key Details

• Leased space: ~62,659 sq ft at 3260 Whipple Road, Union City, CA.
• Term and timing: 12‑year initial term, anticipated commencement ~Aug 1, 2027; option to extend 10 years at market rate.
• Financials: Aggregate base rent over 12 years ≈ $46.7 million; landlord provides a 12‑month rent abatement and a tenant improvement allowance up to $12.5 million.
• Other terms: Company pays pro rata operating expenses, certain taxes/assessments, and posted a $407,910 security deposit upon signing.

Why It Matters
This lease materially expands BillionToOne’s lab capacity for its oncology products to handle test volumes that have exceeded company plans, supporting future testing growth. It also commits the company to a significant long‑term cash outflow (≈$46.7M in base rent) and ongoing facility expenses, while providing up to $12.5M in landlord-funded tenant improvements and a 12‑month rent abatement that partially offsets near‑term cash needs. Investors should view this as a capacity investment with a corresponding long‑term financial obligation disclosed in the 8‑K.
