Heron Therapeutics, Inc. entered into a new long-term office lease for its corporate headquarters with USEF HCG Fenton LLC. The lease covers approximately 16,837 rentable square feet at 25 Fenton Main Street in Cary, North Carolina, with an initial term of about 111 months.
Beginning on the term commencement date, the company will pay monthly base rent of $614,550.50 for the first 12-month period, with base rent increasing by a set percentage in each following 12-month period. Heron will also pay its proportionate share of operating costs, although base rent and estimated operating costs will be abated for a specified number of months after the commencement date. The lease includes a one-time option to extend for an additional 84 months and a one-time right of first refusal on contiguous vacant space.
Heron Therapeutics, Inc. adopted a Tax Benefit Preservation Plan designed to protect its net operating loss carryforwards under Section 382 of the tax code. The Board approved a rights plan that discourages any investor from newly acquiring 4.99% or more of Heron’s common stock, or existing 4.99% holders from increasing their stakes without Board approval, because such ownership changes could limit the company’s ability to use its NOLs.
As part of the plan, the Board declared a dividend of one preferred stock purchase right for each share of common stock outstanding as of August 15, 2025. Each right, exercisable until August 14, 2026 unless earlier redeemed or exchanged, allows the holder to buy one one‑thousandth of a share of Series B Preferred Stock at $7.00, with anti‑dilution protections. The company authorized a new Series B Preferred Stock whose dividend, liquidation and voting terms are structured so that one one‑thousandth of a share is intended to approximate the value of one common share.
