These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of the management of Tempest Therapeutics, as well as assumptions made by, and information currently available to, management of Tempest Therapeutics. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and include words such as "may," "will," "should," "would," "could",
"expect," "anticipate," "plan," "likely," "believe," "estimate," "project," "intend," and other similar expressions. All statements that are not historical facts are forward-looking statements, including any statements regarding the design, initiation, progress, timing, scope and results of clinical trials, the ability of Tempest Therapeutics to advance discussions with potential partners to explore the development of TPST-1120, the anticipated therapeutic benefit, opportunity to improve patient care, and regulatory development of Tempest Therapeutic's product candidates, Tempest Therapeutic's ability to deliver on potential value-creating milestones, the potential use of Tempest Therapeutic's product candidates to treat additional indications,
Tempest Therapeutic's ability to achieve its operational plans, and the sufficiency of Tempest Therapeutic's cash and cash equivalents. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: our strategies, prospects, plans, expectations or objectives for future operations; the progress, scope or timing of the development of our product candidates; the benefits that may be derived from any future products or the commercial or market opportunity with respect to any of our future products; our ability to protect our intellectual property rights; our anticipated operations, financial position, ability to raise capital to fund operations, revenues, costs or expenses; statements regarding future economic conditions or performance; statements of belief and any statement of assumptions underlying any of the foregoing. Many of these risks are described in greater detail in the Form 10-K filed by Tempest Therapeutics with the Securities and Exchange Commission on
March 19, 2024. Except as required by applicable law, Tempest Therapeutics undertakes no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.
Randomized 1L HCC data are superior to standard of care
✓ ORR of 1120 arm is independent of PD-L1 or inflamed tumor status
✓ OS HR favors 1120 and median not reached
✓ Biomarker data further support dual MOA of TPST-1120
✓ Beyond HCC: positive data in RCC & CCA ✓ Three additional programs - diversified portfolio

Activated β-Catenin Pathway Induces PPARα Expression and Reliance on FAO
Identifying cancers with increased sensitivity to TPST-1120
Activated β-catenin pathway
Increased FAO in b-catenin-activated mouse hepatocytes
Refs: Senni (2019) Gut, 68:322.
NT: Normal liver tissue M: Mt CTNNB1 HCC
NM: Non-mt CTNNB1 HCC
Increased FAO in b-catenin-activated mouse liver is PPARa-dependent
Preclinical HCC Data Support Clinical Development Strategy
β-catenin pathway frequently activated in HCC: Potential Biomarker
• Wnt/β-catenin pathway is critical for stem cell regeneration, and tumorigenesis (i.e., EMT)
• Activation of WNT/β-catenin pathway occurs frequently in HCC: 40-70%1,2,3
• PPARα expression is higher in CTNNB1-mutated human HCC
• β-catenin activated HCC confers dependence on FAO for metabolism
• Available genetic tests for CTNNB1, APC and modulators of β-catenin pathway
