AnaptysBio subleases 45,057 sq ft San Diego space to First Tracks Biotherapeutics

Neutral product/contract Written later 1.01

AnaptysBio entered a 12-month sublease on June 15, 2026, leasing about 45,057 rentable square feet of its San Diego premises to First Tracks Biotherapeutics. The company stays responsible for its underlying master lease, and the sublease ends if its own tenancy ends, so the deal shifts occupancy costs to a subtenant without changing the company's core obligations.

  • Sublease covers about 45,057 rentable square feet at 10770 Wateridge Circle, San Diego, under a master lease with Wateridge Property Owner, LP.
  • First Tracks pays monthly rent equal to the Basic Rent and Additional Rent AnaptysBio owes under the master lease, due in advance on the first of each month.
  • Initial term is 12 months from June 15, 2026; First Tracks has a renewal option capped at April 4, 2028 and may terminate on three months' notice.
