Spectral Medical Announces First Quarter 2026 Financial Results and Provides Corporate Update

• PMA submission targeted for May 29, 2026 in alignment with FDA
• Vantive commits to additional funding support ahead of PMA acceptance milestone

TORONTO, May 08, 2026 (GLOBE NEWSWIRE) — Spectral Medical Inc. (“Spectral” or the “Company”) (TSX: EDT), a late-stage theranostic company advancing therapeutic options for sepsis and septic shock, today announced its financial results for the first quarter ended March 31, 2026 and provided a corporate update.

The first quarter of 2026 marked continued progress across regulatory, clinical and commercial readiness initiatives as the Company advances toward submission of its U.S. Food and Drug Administration (“FDA”) Premarket Approval (“PMA”) application for Toraymyxin™ (“PMX”). During the quarter and subsequent to quarter-end, Spectral further strengthened the clinical and scientific foundation supporting PMX, highlighted by the publication of the Tigris trial in The Lancet Respiratory Medicine and presentation at the Society of Critical Care Medicine Annual Congress in Chicago

The Company is targeting a PMA submission date of May 29, 2026, a timeline established in coordination with the FDA to support both submission readiness and efficient allocation of review resources. The timing reflects incorporation of complete 12-month mortality data from the Tigris study, as well as completion of key non-clinical modules, including human factors engineering testing, to support a complete and compliant submission.

“Our focus remains on executing a high-quality and comprehensive PMA submission while advancing commercialization readiness alongside our partner Vantive,” said Chris Seto, Chief Executive Officer of Spectral Medical. “We are encouraged by the continued support from Vantive, including their decision to provide additional funding ahead of the PMA acceptance milestone. We believe this reflects a shared commitment to the PMX program and provides additional flexibility as we execute against this important regulatory step. The progress achieved during the quarter reinforces the strength of the Tigris data and the totality of evidence supporting PMX as we move toward submission and, ultimately, potential approval in the United States.”

John A. Kellum, Chief Medical Officer of Spectral Medical, added, “The consistency of benefit observed across endpoints, particularly at later timepoints, supports the concept that treatment effects become more apparent as patients recover beyond the acute phase of septic shock.”

Corporate Highlights During & Subsequent to the First Quarter of 2026

Tigris

• Tigris manuscript published on March 23, 2026:
  • The Tigris manuscript was published in The Lancet Respiratory Medicine, one of the world’s leading peer-reviewed journals in critical care and respiratory medicine.
  • The publication confirms the previously reported positive findings for the primary and key secondary endpoints announced in August 2025, while providing additional analyses on survival, safety, secondary and sensitivity analyses:
    • Confirms positive results for primary and key secondary endpoints with 95.3% and 99.4% probability of benefit for PMX at 28-day and 90-day mortality
    • After adjusting for baseline severity, absolute risk reduction for mortality of 10.3% at 28-days and 15.5% at 90-days
    • Kaplan-Meier survival curves demonstrated continued separation beyond day 28, indicating that the survival benefit observed with PMX was sustained over time.
    • Safety profile consistent with standard of care with no significant difference in adverse events
  • The findings further suggest that treatment effects observed at earlier timepoints are sustained and may become more apparent over longer-term follow-up, consistent with the recovery trajectory of critically ill septic shock patients.
• Society of Critical Care Medicine (“SCCM”) Critical Care Congress, Chicago March 24, 2026:
  • Results from the Tigris study presented on March 24, 2026 at the SCCM Annual Congress in the Late-Breaking Studies Affecting Patient Outcomes session
  • Presented by Dr. Javier Neyra, first author of the Tigris paper
• PMA Submission:
  • PMA submission date targeted for May 29, 2026.
  • Timing established in coordination with the FDA
    • Supports submission readiness and efficient allocation of review resources
  • Based on FDA feedback, 12-month mortality data from the Tigris study is to be incorporated into the PMA submission
  • The Company believes the inclusion of complete 12-month mortality outcomes will further inform the FDA’s review and contribute to the totality of clinical evidence supporting PMX for the treatment of endotoxic septic shock.
  • Spectral currently anticipates being in a position to report topline 12-month mortality data in June 2026, subject to the completion of additional data analysis.

PMX Commercialization

• Ongoing collaboration with Vantive on commercialization planning.
• Vantive intends to submit 510(k) application for its PrisMax system, expected to be the primary ICU platform for PMX treatment.
• Market readiness efforts are aligned with potential FDA approval timelines.

Financing

• On May 07, 2026, the Company entered into a side letter agreement with Vantive US Healthcare LLC in respect of its existing senior secured promissory note.
• Under the agreement, Vantive agreed, at its sole discretion, to advance US$1.0 million as a partial funding of the US$2.0 million Tranche D, notwithstanding that the related milestone (PMA filing acceptance) had not yet been satisfied.
• Upon funding, the advance is treated as an amount drawn under the promissory note.
• The remaining US$1.0 million of Tranche D remains subject to the original milestone conditions, and Vantive has no obligation to fund any further amounts unless such conditions are satisfied or otherwise agreed.

Financial Review

Revenue for the three-months ended March 31, 2026 was $891,000 compared to $572,000 for the same three-month period last year, representing an increase of $319,000, or 56%. The increase was primarily driven by higher Product revenue, including proprietary biochemical sales, instrumentation sales, and PMX pre-commercialization activities, partially offset by a decrease in Royalty revenue and EAA diagnostic sales mix. Product revenue increased to $386,000 from $176,000 in the prior-year period.

Operating expenses for the three-months ended March 31, 2026, were $3,633,000 compared to $13,049,000 for the same period in the preceding year, a decrease of $9,416,000 or 72 %. The decrease was primarily driven by a lower fair value adjustments on derivative liabilities (a non-cash item), as well as foreign exchange adjustments on derivative liabilities and convertible debentures. These variances resulted largely from changes in market assumptions and the market price used to calculate the option feature. Excluding the derivative fair value adjustment and foreign exchange adjustments on derivative liabilities and convertible debentures, expenses increased period-over-period, primarily due to higher interest expense, regulatory and investor relations costs, facilities costs and share-based compensation. Increase in interest expense reflects higher outstanding debt related to the Company’s convertible notes and the Vantive promissory note, including a full-quarter accrual of paid-in-kind (PIK) interest. Interest expense of $1,600,000 which relates to the three months ended March 31, 2026 in relation to convertible notes previously issued and May 2025 and August 2025 promissory notes issued.

Clinical development and regulatory program costs (as disclosed in Note 13 of the consolidated financial statements) were $768,000 for the three-months ended March 31, 2026 compared to $1,585,000 for the same period in the prior year. A significant portion of clinical trial and regulatory costs consists of consulting and professional fees paid to contract research organizations, clinical sites, and other clinical and regulatory consultants .The decrease in clinical costs reflects the completion of Tigris enrollment in April 2025 and reduced clinical site activity, partially offset by an increase in activities related to the Company’s ongoing FDA PMA submission, including regulatory consulting, data analysis, and other submission-readiness work. Cumulative trial and regulatory program costs total as of March 31, 2026 was $59,932,000.

Loss for the three-months ended March 31, 2026 was $2,938,000 ($0.01 per share) compared to a loss of $12,605,000 ($0.04 per share) for the same period in the prior year. The decreased loss of $9,667,000 was due to decreased operating expenses, primarily due to decreased fair value adjustment of derivative liability on March 31, 2026.
