Shattuck Labs Reports Second Quarter 2026 Financial Results and Recent
Shattuck Labs, Inc. (STTK) filed an SEC Form 8-K — Results of Operations and Financial Condition. Exhibit 99.1 Shattuck Labs Reports Second Quarter 2026 Financial Results and Recent Business Highlights – Phase 1 clinical trial results for SL-325 demonstrated a favorable safety profile, a potentially best-in-mechanism immunogenicity profile, and durable DR3 blockade of TL1A bi
How this was made
The 30-second read
Why it matters
The most tradable elements are the specific Phase 1 SL-325 findings (immunogenicity rate, durable TL1A blockade, no DR3 agonism), the planned Phase 2b initiation in Q3 2026, and the strengthened balance sheet expected to fund operations into 2029.
Market read
Traders can update probability-weighted biotech success and financing risk based on new clinical readouts and explicit cash runway guidance.
What to watch
Cash runway into 2029 reduces financing pressure, but the company still faces dilution risk if Phase 2b or later trials require additional capital before results in 1H 2028.
Shattuck Labs Reports Second Quarter 2026 Financial Results and Recent Business Highlights
Shattuck reported favorable Phase 1 findings for SL-325, remains on track to initiate its RECEPTIVE-CD1 Phase 2b Crohn’s disease trial in the third quarter of 2026, and reported $208.3 million of cash, cash equivalents and short-term investments expected to fund operations into 2029. R&D expense and net loss were higher than the prior-year period.

into 2029 outlook
- NoteShattuck’s current cash and cash equivalents, and short-term investments are expected to fund operations into 2029.
What drove it
- Phase 1 clinical trial results for SL-325 showed only 3.7% of participants developing antidrug antibodies.
- The Phase 1 trial showed complete blockade of TL1A binding to DR3 for over 3 months expected at doses of 1 mg/kg and higher.
- SL-325 was well tolerated with a favorable safety profile consistent with the TL1A inhibitor class, with no evidence of DR3 agonism.
- The RECEPTIVE-CD1 Phase 2b trial is expected to evaluate three dose levels of SL-325 compared with placebo in approximately 232 patients.
- SL-846 is in an ongoing IND-enabling GLP toxicology study in non-human primates.
Concerns
- R&D expenses were $11.7 million for the quarter ended June 30, 2026, as compared to $8.7 million for the quarter ended June 30, 2025.
- Net loss was $15.2 million for the quarter ended June 30, 2026, as compared to a net loss of $12.5 million for the quarter ended June 30, 2025.
- The cash runway guidance excludes any additional capital that may be received, proceeds from business development transactions, and/or additional costs associated with clinical development activities that may be undertaken.
- The RECEPTIVE-CD1 trial's primary endpoint data are expected in the first half of 2028.
What to watch
- Initiation of the RECEPTIVE-CD1 Phase 2b clinical trial of SL-325 in the third quarter of 2026.
- Preclinical data for SL-846 at UEG Week, to be held October 17-20, 2026.
- Initial Phase 1 healthy volunteer clinical trial data for SL-846 expected in 2027.
- Endoscopic response data at 12 weeks from RECEPTIVE-CD1, expected in the first half of 2028.
Balance sheet and cash flow
- As of June 30, 2026, cash and cash equivalents and short-term investments were $208.3 million, as compared to $50.5 million as of June 30, 2025.
- Shattuck completed an underwritten public offering with aggregate gross proceeds of approximately $86.2 million.
- As of July 1, 2026, all of the common stock warrants issued in the Company's August 2025 private placement have been exercised, resulting in aggregate gross proceeds of approximately $57.1 million.
Analysis
Shattuck’s quarter was defined by clinical progress and capital formation rather than commercial activity. The company reported Phase 1 results for SL-325 that it described as showing a favorable safety profile, only 3.7% of participants developing antidrug antibodies, no evidence of DR3 agonism, and complete blockade of TL1A binding to DR3 for over 3 months expected at doses of 1 mg/kg and higher. The company expects to initiate the RECEPTIVE-CD1 Phase 2b Crohn’s disease trial in the third quarter of 2026.
The planned Phase 2b study is a major execution milestone. RECEPTIVE-CD1 is designed as a randomized, double-blind, placebo-controlled trial evaluating three SL-325 dose levels against placebo in approximately 232 patients. Its primary endpoint is endoscopic response at 12 weeks, with data expected in the first half of 2028. Patients will continue treatment through a maintenance phase to 50 weeks, allowing the company to evaluate potential accumulating efficacy during maintenance.
Expense trends reflect continued pipeline investment. R&D expenses were $11.7 million, compared with $8.7 million in the prior-year quarter, while G&A expenses were $4.5 million compared with $4.4 million. Net loss was $15.2 million, compared with $12.5 million in the prior-year quarter. The filing does not provide prior-quarter financial comparisons, revenue, gross profit, operating income, or cash-flow metrics.
Liquidity was materially strengthened. Cash, cash equivalents and short-term investments were $208.3 million as of June 30, 2026, compared with $50.5 million as of June 30, 2025. The company also disclosed an underwritten public offering with aggregate gross proceeds of approximately $86.2 million and warrant exercises that generated aggregate gross proceeds of approximately $57.1 million as of July 1, 2026. Management expects current cash, cash equivalents and short-term investments to fund operations into 2029, subject to the stated exclusions for additional capital, business development proceeds, and potential additional clinical-development costs.
Beyond SL-325, SL-846 remains in an IND-enabling GLP toxicology study in non-human primates. Shattuck expects to present SL-846 preclinical data at UEG Week in October 2026, initiate a Phase 1 healthy-volunteer trial, and report initial data in 2027. The central figures to monitor are execution on the third-quarter RECEPTIVE-CD1 initiation, the timing and content of SL-846 data, R&D spending as clinical programs advance, and maintenance of the stated runway into 2029.
Management, verbatim
The Phase 1 clinical data for SL-325 has checked all of the boxes and positions SL-325 as a potentially winning antibody in the TL1A/DR3 axis heading into Phase 2 clinical development,

Background
This is an SEC Form 8-K (Item 2.02) with an attached earnings release covering Q2 2026 financials and SL-325/SL-846 development updates.
Ticker impact
Shattuck reported Q2 2026 results and disclosed Phase 1 SL-325 data, including 3.7% antidrug antibodies and durable TL1A blockade.
Near-term upside bias as traders price improved efficacy/safety signals and reduced financing risk into 2029.
The filing is a primary disclosure (8-K with earnings release) and includes specific clinical and balance-sheet datapoints that can shift biotech risk perception and funding expectations.
Market effects
Supports sentiment for DR3/TL1A pathway immunology peers by reinforcing target biology and dosing durability narrative.
Limited, company-specific biotech catalyst with no clear regional macro linkage.
Moderate for global IBD immunology investors tracking DR3/TL1A bispecific/monoclonal development timelines.
Counterpoint
Phase 1 immunogenicity and binding blockade do not guarantee Phase 2b endoscopic response; efficacy may disappoint despite favorable safety.
