Surrozen Reports Second Quarter 2026 Financial Results and Provides Business Update

Planned IND submission for SZN-8141 in diabetic macular edema by the end of the third quarter of 2026

Expect to initiate SZN-8141 Phase 1b/2a study, DUET, by year-end 2026 with initial data anticipated in the second half of 2027

U.S. Patent Trial and Appeal Board denies institution of post-grant review petition challenging Surrozen patent

SOUTH SAN FRANCISCO, Calif., August 6, 2026 (GLOBE NEWSWIRE) -- Surrozen, Inc. (“Surrozen” or the “Company”) (Nasdaq: SRZN), a biotechnology company pioneering targeted therapeutics to harness the power of Wnt signaling to address the underlying drivers of disease in sight-threatening ophthalmic conditions, today announced financial results for the second quarter ended June 30, 2026 and provided a business update.

“We continue to execute our strategy of building a leading ophthalmology franchise centered on the therapeutic potential of Wnt biology,” said Craig Parker, Chief Executive Officer of Surrozen. “The planned DUET Phase 1b/2a study represents an important step in the clinical development of SZN-8141 and reflects our commitment to generate meaningful evidence to guide future development across retinal vascular disease. In addition, the recent U.S. Patent Trial and Appeal Board (PTAB) decision denying the institution of Merck’s post-grant review petition reinforces our intellectual property position. Together, these advancements further strengthen the foundation of our ophthalmology franchise and support our long-term growth strategy.”

Business Highlights, Recent Developments and Upcoming Milestones

The Company continues to advance its ophthalmology pipeline (SZN-8141 and SZN-8143) and expects to submit an Investigational New Drug (IND) application for SZN-8141 by the end of the third quarter of 2026 and initiate the DUET Phase 1b/2a study in diabetic macular edema (DME) patients by year-end 2026

In June 2026, Boehringer Ingelheim achieved a development milestone under the SZN-413 license agreement following the initiation of a Phase 1 study

In July 2026, the U.S. PTAB denied institution of Merck’s post-grant review petition challenging certain claims of Surrozen’s U.S. Patent No. 12,297,278, determining that the petition failed to show a reasonable likelihood of prevailing with respect to the challenged claims

DUET: Phase 1b/2a Clinical Trial in Diabetic Macular Edema

SZN-8141 will be evaluated in a Phase 1b/2a clinical trial in DME called DUET, designed to assess safety, tolerability, and early signs of biological and clinical activity. The trial consists of an open-label Phase 1b single-ascending-dose portion enrolling both treatment-naïve and previously treated patients with DME (Part 1), followed by a randomized, double-masked Phase 2a dose-expansion portion in treatment-naïve patients with DME (Part 2).

In Part 1, patients will receive a single intravitreal injection of SZN-8141 and be followed for approximately three months to evaluate safety and tolerability, as well as pharmacokinetics, immunogenicity, and exploratory measures of retinal function and anatomy including best-corrected visual acuity (BCVA), optical coherence tomography (OCT), OCT angiography (OCT-A), and ultra-widefield fluorescein angiography.

Part 2 is expected to evaluate two dose levels of SZN-8141 compared with Vabysmo® (faricimab-svoa) in approximately 60 treatment-naïve patients with DME. Patients are planned to receive three monthly doses followed by an additional four-month follow-up period to assess durability of effect. Key outcome measures include the same functional and anatomic measurements as in Part 1.

DUET is anticipated to initiate by year-end 2026, with initial data expected in the second half of 2027. The Company is also planning to develop SZN-8141 in neovascular age-related macular degeneration and is evaluating development in other retinal vascular diseases.

Second Quarter 2026 Financial Highlights

- Cash Position: Cash and cash equivalents were $102.0 million as of June 30, 2026, compared to $106.9 million as of March 31, 2026.

- Revenue:

•

Collaboration and License Revenue: Collaboration and license revenue was $5.0 million for the quarter ended June 30, 2026 attributable to the recognition of a milestone achieved under a collaboration and license agreement with Boehringer Ingelheim in June 2026. The Company did not have any collaboration and license revenue for the quarter ended June 30, 2025.

•

Research Service Revenue – Related Party: Research service revenue from a related party was zero for the quarter ended June 30, 2026, compared to $1.0 million for the same period in 2025, driven by the termination of the research collaboration with TCGFB, Inc., effective in November 2025.

- Operating Expenses:

•

Research and Development Expenses: R&D expenses were $8.5 million for the quarter ended June 30, 2026, compared to $6.0 million for the same period in 2025, primarily reflecting a $1.7 million increase in manufacturing costs, lab expenses and consulting fees for our ophthalmology programs and a $1.0 million increase in employee-related expenses primarily related to stock-based compensation, offset by a $0.3 million decrease in clinical expenses as a result of the discontinuation of clinical development of SZN-043.

•

General and Administrative Expenses: G&A expenses were $6.9 million for the quarter ended June 30, 2026, compared to $4.0 million for the same period in 2025, primarily due to a $1.5 million increase in employee-related expenses primarily related to stock-based compensation and a $1.3 million increase in professional service fees primarily related to the defense of our intellectual property portfolio.

- Other Income and Expenses:

•

Interest Income: Interest income was $0.9 million for the quarter ended June 30, 2026, compared to $1.0 million for the same period in 2025, as a result of a decrease in market interest rates on our money market funds.

•

Gain on Change in Fair Value of Tranche Liability: Gain on change in fair value of tranche liability related to the 2025 PIPE was $39.2 million for

the quarter ended June 30, 2026, compared to $31.5 million for the same period in 2025, attributable to the non-cash change in fair value of tranche liability, which was primarily driven by the decrease in our stock price over the period.

•

Other Income, Net: Other income, net was $20.4 million for the quarter ended June 30, 2026, compared to $16.2 million for the same period in 2025, primarily driven by the non-cash change in fair value of warrant liabilities.

- Net Income: Net income was $50.2 million, including non-cash gains of $59.6 million on changes in fair value of tranche liability and warrant liabilities, for the quarter ended June 30, 2026, compared to $39.7 million, including non-cash gains of $47.6 million on changes in fair value of tranche liability and warrant liabilities, for the same period in 2025.

Surrozen’s Ophthalmology Portfolio

About SZN-8141 for Retinal Diseases

Surrozen is developing SZN-8141 for the treatment of diabetic macular edema (DME) and neovascular age-related macular degeneration (wet AMD). SZN-8141 combines Frizzled 4 (Fzd4) agonism and vascular endothelial growth factor (VEGF) antagonism and has the potential to provide benefits over treatment with single mechanism agents against these targets. The current standard of care for diabetic retinopathy (including DME), retinal vein occlusion and wet AMD is intravitreal administration of anti-VEGF therapies, including monotherapies and dual-pathway agents targeting VEGF and Ang-2. In addition, MK-3000, a Fzd4 monotherapy, has demonstrated proof of concept in DME in a clinical trial. We believe SZN-8141 has the potential to treat multiple retinopathy indications and be differentiated from existing therapies. Data generated in preclinical models of retinopathy demonstrated that SZN-8141 stimulated Wnt signaling and induced normal retinal vessel regrowth while suppressing pathological vessel growth.

About SZN-8143 for Retinal Diseases

Surrozen is developing SZN-8143 for the treatment of DME, wet AMD, and uveitic macular edema (UME). SZN-8143 combines Fzd4 agonism, VEGF antagonism, and interleukin-6 (IL-6) antagonism and may have benefits over single mechanism

agents against these targets. The current standard of care for diabetic retinopathy (including DME), retinal vein occlusion and wet AMD is intravitreal administration of anti-VEGF therapies, including monotherapies and dual-pathway agents targeting VEGF and Ang-2. In addition, MK-3000, a Fzd4 monotherapy, has demonstrated proof of concept in DME in a clinical trial. The Company believes SZN-8143 has the potential to treat multiple retinopathy indications and be differentiated from existing therapies. Data generated in preclinical models of retinopathy demonstrated that SZN-8143 stimulated Wnt signaling and induced normal retinal vessel regrowth while suppressing pathological vessel growth.

Partnership with Boehringer Ingelheim

SZN-413 is a bi-specific antibody targeting Fzd4-mediated Wnt signaling designed using Surrozen’s SWAP™ technology. It is currently being developed for the treatment of retinal diseases by Boehringer Ingelheim. Data generated by Surrozen with SZN-413 in preclinical models of retinopathy demonstrated that SZN-413 potently stimulated Wnt signaling in the eye, induced normal retinal vessel regrowth, suppressed pathological vessel growth and reduced vascular leakage.

About Surrozen

If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that Surrozen presently does

not know, or that Surrozen currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Surrozen’s expectations, plans, or forecasts of future events and views as of the date of this press release. Surrozen anticipates that subsequent events and developments will cause its assessments to change.
