**EXHIBIT 99.1**

**Palisade Bio Reports First Quarter 2026 Financial Results and Highlights Continued Clinical Progress of PALI-2108**

*Advancing potentially best-in-class once-daily oral, locally-activated PDE4 inhibitor prodrug for treatment of IBD*

*Phase 2 Ulcerative Colitis (UC) trial expected to commence 3Q 2026*

 *Strong balance sheet expected to support execution through key clinical readouts*

**Denver, CO, May 12, 2026** — Palisade Bio, Inc. (Nasdaq: PALI) ("Palisade Bio" or the "Company"), a clinical-stage biopharmaceutical company developing next-generation, once-daily, oral PDE4 inhibitor prodrugs designed for targeted delivery to the terminal ileum and colon, today reported financial results for the first quarter ended March 31, 2026 and highlighted continued clinical advancements of its lead program, PALI-2108, including recent data readouts and anticipated Phase 2 trial initiations.

Building on positive Phase 1a and Phase 1b ulcerative colitis cohort data previously reported, the Company recently reported results from the Phase 1b fibrostenotic Crohn's disease ("FSCD") cohort, extending the clinical support for the continued development of PALI-2108 across multiple inflammatory bowel disease ("IBD") indications. The data demonstrated sustained exposure of the active metabolite above IC90 thresholds, along with favorable distribution to colon tissue, supporting consistent target engagement at the site of disease. In addition, pharmacodynamic findings showed modulation of key inflammatory and fibrotic pathways, reinforcing the potential of PALI-2108 to address both components of IBD. The program continues to demonstrate a favorable safety and tolerability profile, reinforcing confidence in the potential of PALI-2108 as it advances into Phase 2 development.

"We continue to see a consistent and differentiated profile emerging for PALI-2108 across IBD," said JD Finley, Chief Executive Officer of Palisade Bio. "The totality of data generated to date supports our decision to advance into Phase 2 development in both ulcerative colitis and Crohn's disease. With consistent target engagement, evidence of activity across key inflammatory and fibrotic pathways, and a favorable safety profile, we are increasingly confident in the potential of PALI-2108 as we move into development this year."

**EXHIBIT 99.1**

**Recent Highlights and Anticipated Milestones**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Completed Phase 1a/b for PALI-2108, Reported Positive Data**

✓Favorable safety and tolerability profile

✓Evidence of target engagement in ileal and colon tissue

✓Early signals of clinical activity in Crohn's disease

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Advancing Toward Phase 2** 

oIND submission for Phase 2 UC trial expected in 2Q 2026

oIND submission for Phase 2 CD trial expected in 2H 2026

oPhase 2 UC trial initiation targeted for Q3 2026

oPhase 2 CD trial initiation targeted for Q1 2027

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Well-Capitalized Through Potential Key Value Inflection Points** 

oPhase 2 UC readout (expected in 2H 2027)

oPhase 2 CD readout (expected early 2028)

PALI-2108 is an orally administered, once-daily PDE4 inhibitor prodrug designed for targeted activation in the ileum and colon. Its localized bioactivation is intended to enable sustained target inhibition at the site of inflammation while minimizing systemic exposure and improving tolerability.

**Summary of Financial Results** 

Research and development expenses were $6.4 million for the three months ended March 31, 2026, compared to $1.0 million for the three months ended March 31, 2025. The increase of $5.4 million was primarily attributable to (i) an increase in research and development employee-related expenses, including increased non-cash share-based compensation expense, (ii) a net increase in clinical trial-related expenses associated with the ongoing clinical trials of PALI-2108, and (iii) an increase in chemistry, manufacturing and controls ("CMC") expenses.

General and administrative expenses were $4.4 million for the three months ended March 31, 2026, compared to $1.4 million for the three months ended March 31, 2025. The increase of $3.0 million was primarily attributable to higher employee-related expenses, including increased non-cash share-based compensation expense, as well as higher professional fees.

As of March 31, 2026, the Company had cash and cash equivalents of $132.6 million and believes that its cash on hand is sufficient to fund its operations through major clinical development milestones, including a Phase 2 primary efficacy readout of PALI-2108 for UC that is expected in the second half of 2027 and a Phase 2 primary efficacy readout of PALI-2108 CD that is expected in early 2028.
