Recent Business Highlights
Company Financed to Anticipated Profitability
$289 Million Public Equity Offering in October 2025. On October 21, 2025, the company announced a public offering of common stock with gross proceeds of approximately $251.4 million, consisting of 11,425,000 shares sold at a public offering price of $22.00 per share. Following the announcement, the underwriters exercised their over-allotment option to purchase an additional 1,713,750 shares of common stock at a public offering price of $22.00 per share for an additional $37.7 million of gross proceeds. Total gross proceeds from the equity offering consisting of 13,138,750 shares sold were $289.1 million. $170 Million in Upfront and Potential Near-Term Milestones from DRI Royalty Financing. Viridian closed a royalty financing with DRI Healthcare Acquisitions LP (DRI) in October 2025 for up to $300 million total capital, including $55 million upfront and $115 million in near-term milestones tied to positive VRDN-003 topline data and U.S. veligrotug marketing approval. Viridian will pay DRI tiered royalties on annual U.S. net sales of veligrotug and VRDN-003. Amended Hercules Capital Credit Facility. The company signed an amended agreement with Hercules Capital, Inc. (Hercules) in October 2025, which provides for up to $300 million in available capital and extends Viridian’s interest-only payment period. The agreement required a $50 million draw at closing, resulting in $30 million of immediate proceeds after repayment of the company’s prior Hercules facility. The new facility provides additional non-dilutive capital at the company’s discretion upon achievement of specified milestones. The company believes that its current cash, potential near-term milestones from the royalty agreement, and anticipated revenues, if both veligrotug and VRDN-003 are approved, will fund Viridian’s current business plans through profitability.

About Viridian Therapeutics
Viridian is a biopharmaceutical company focused on discovering, developing, and commercializing potential best-in-class medicines for patients with serious and rare diseases. Viridian’s expertise in antibody discovery and protein engineering enables the development of differentiated therapeutic candidates for previously validated drug targets in commercially established disease areas.
Viridian is advancing multiple candidates in the clinic for the treatment of patients with thyroid eye disease (TED) and a portfolio of inhibitors to the neonatal Fc receptor (FcRn). In TED, the company is conducting a pivotal program for veligrotug, including two completed global phase 3 clinical trials (THRIVE and THRIVE-2), to evaluate its efficacy and safety in patients with active and chronic TED. Both THRIVE and THRIVE-2 reported positive topline data, meeting all the primary and secondary endpoints of each study. Viridian is also advancing VRDN-003 as a potential best-in-class subcutaneous therapy for the treatment of TED, including two ongoing global phase 3 pivotal clinical trials (REVEAL-1 and REVEAL-2), to evaluate the efficacy and safety of VRDN-003 in patients with active and chronic TED.
In addition to its TED portfolio, Viridian is advancing a novel portfolio of FcRn inhibitors, including VRDN-006 and VRDN-008, which has the potential to be developed in multiple autoimmune diseases.
Viridian is based in Waltham, Massachusetts. For more information, please visit www.viridiantherapeutics.com. Follow Viridian on LinkedIn and X.
About Veligrotug
Veligrotug is an intravenously delivered, anti-insulin-like growth factor-1 receptor (IGF-1R) antibody in phase 3 development for thyroid eye disease, with the potential to be the IV treatment-of-choice for active and chronic TED patients. Based on clinical data to date, veligrotug has demonstrated robust clinical activity and was generally well-tolerated.
Both pivotal phase 3 clinical trials, THRIVE and THRIVE-2, reported positive topline data, meeting all the primary and secondary endpoints of each study. In these studies, veligrotug demonstrated a rapid onset of clinical benefit and statistically significant and clinically meaningful effect on multiple diplopia endpoints. This is the first data set from a global phase 3 clinical trial in chronic TED patients to demonstrate statistically significant diplopia response and resolution.
About VRDN-003
VRDN-003 is a subcutaneously delivered, half-life extended, potential best-in-class anti-IGF-1R antibody. VRDN-003 has the same binding domain as veligrotug and was engineered to have a longer half-life. In a phase 1 healthy volunteer clinical trial, VRDN-003 showed a half-life of 40-50 days, 4-5x that of veligrotug. Pharmacokinetics modeling predicted that VRDN-003 exposure levels after Q4W and Q8W dosing achieve the range of veligrotug exposures that showed robust clinical activity in a two-infusion phase 2 clinical trial in TED. Viridian is conducting a pivotal program for VRDN-003, including two phase 3 clinical trials assessing VRDN-003 dosed Q4W and Q8W in active and chronic TED, REVEAL-1 and REVEAL-2, respectively.
About VRDN-006 and VRDN-008
VRDN-006 is a highly selective Fc fragment which inhibits FcRn and is designed to be a convenient subcutaneous and self-administered option for patients. Viridian is studying VRDN-006 in a first-in-human phase 1 clinical trial in healthy volunteers.
VRDN-008 is a half-life extended FcRn inhibitor comprising an Fc fragment and an albumin-binding domain designed to prolong IgG suppression and provide a potentially best-in-class subcutaneous option for patients. VRDN-008 showed a longer half-life than efgartigimod and led to a more sustained IgG reduction after a single, high dose head-to-head study in non-human primates.
