Aligos Therapeutics Amends HQ Lease, Extends Term to 2034

What Happened
Aligos Therapeutics announced it entered into a First Amendment to its lease for headquarters space at One Corporate Drive, 2nd Floor, South San Francisco, CA. The amendment, effective September 10, 2026, extends the lease term from March 31, 2027 to March 31, 2034 and sets a schedule of base monthly rent (per rentable square foot) for each year of the extended term. The Company will also be required to pay a specified share of certain landlord-paid expenses and will receive a rent abatement for ten months, subject to there being no material default under the lease.

Key Details

• Lease extension: new expiration date March 31, 2034 (previously March 31, 2027).
• Rent schedule (base monthly rent, per rentable sq ft): $4.650 (4/1/27–3/31/28); $4.813 (4/1/28–3/31/29); $4.981 (4/1/29–3/31/30); $5.156 (4/1/30–3/31/31); $5.336 (4/1/31–3/31/32); $5.523 (4/1/32–3/31/33); $5.716 (4/1/33–3/31/34).
• Rent abatement: ten months (4/1/27–1/31/28), conditional on no material default.
• Termination options: one-time early termination as of March 31, 2031 with payment of $2,476,429.22 if notice given by 3/31/30; or penalty-free termination with ≥30 days’ notice if the Company and landlord execute a new lease for ≥60,000 rentable sq ft in the same project or another landlord-owned project.
• Extension option revised: the existing post-term extension option changed from one 8-year option to one 7-year option, exercisable for the seven-year period immediately following the extended term.

Why It Matters
This amendment secures Aligos’ headquarters location through 2034, providing long-term occupancy certainty but also locking in increasing rental costs over time. The ten-month rent abatement reduces near-term cash outflow, while the scheduled per-square-foot rent increases and responsibility for a portion of property expenses will affect future occupancy costs and operating expenses (e.g., SG&A). The early termination options give the company flexibility—at a known buyout cost of about $2.48 million or potentially penalty-free if it relocates to a larger space arranged with the landlord. The full First Amendment will be filed as an exhibit to the Company’s Form 10-Q for the quarter ending September 30, 2026.
