Research and Development Expenses: R&D expenses were $9.3 million for the quarter ended March 31, 2026, compared to $6.6 million for the same period in 2025, primarily reflecting a $2.4 million increase in manufacturing costs, lab expenses and consulting fees for our ophthalmology programs and a $1.2 million increase in employee-related expenses, offset by a $0.9 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 $6.1 million for the quarter ended March 31, 2026, compared to $4.0 million for the same period in 2025, primarily due to a $1.1 million increase in employee-related expenses and a $1.0 million increase in professional service fees.

- Other Income and Expenses:

Interest Income: Interest income was $0.9 million for the quarter ended March 31, 2026, compared to $0.3 million for the same period in 2025, as a result of an increase in cash and cash equivalents.
Loss on Amendment and Cancellation of Warrants: Loss on amendment and cancellation of warrants originally issued in a private placement in 2024 was $2.1 million for the quarter ended March 31, 2025, due to the non-cash change in fair value of warrant liabilities as a result of the amendment and cancellation of warrants in March 2025. There was no such corresponding loss for the quarter ended March 31, 2026.
Loss on Execution of the 2025 PIPE: Loss on execution of the private placement in March 2025 (2025 PIPE) was $71.1 million for the quarter ended March 31, 2025, reflecting the non-cash loss recognized upon the initial execution of the 2025 PIPE as committed proceeds from the 2025 PIPE were less than the fair value of the tranche liability recognized at contract execution date. There was no such corresponding loss for the quarter ended March 31, 2026.
Loss/Gain on Change in Fair Value of Tranche Liability: Loss on change in fair value of tranche liability related to the 2025 PIPE was $76.9 million for the quarter ended March 31, 2026, compared to a gain of $16.3 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 increase in our stock price.
Gain on Settlement of Tranche Liability: Gain on settlement of tranche liability related to the 2025 PIPE was $1.1 million for the quarter ended March 31, 2025 related to the proceeds from the sale of securities in the 2025 PIPE being greater than the net value of securities issued on settlement date. There was no such corresponding gain for the quarter ended March 31, 2026.
Other Expense/Income, Net: Other expense, net was $41.1 million for the quarter ended March 31, 2026, compared to a net other income of $38.0 million for the same period in 2025, primarily driven by a $81.7 million non-cash change in fair value of warrant liabilities, offset by $2.7 million financing transaction costs incurred in 2025 for the 2025 PIPE.

- Net Loss: Net loss was $127.5 million, or ($11.65) per share for the quarter ended March 31, 2026, compared to a net loss of $27.0 million, or ($7.43) per share, 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). SRZN-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 clinical trials. 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 clinical trials. 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.

Under the terms of the agreement, BI received an exclusive, worldwide license to develop SZN-413 and other Fzd4-specific Wnt-modulating molecules for all purposes, including as a treatment for retinal diseases, in exchange for an upfront payment to Surrozen of $12.5 million and up to $586.5 million in success-based development, regulatory, and commercial milestone payments, in addition to mid-single digit to low-double digit royalties on sales.
