 | countries other than the United States may have patent laws less favorable to patentees than those upheld by U.S.     
 courts, allowing foreign competitors a better opportunity to create, develop and market competing product candidates; |

| • |     | the claims of any patent issuing based on Kineta’s patent applications may not provide protection against 
 competitors or any competitive advantages, or may be challenged by third parties;                         |

| • |     | if enforced, a court may not hold that Kineta’s patents are valid, enforceable and infringed; |

| • |     | Kineta may need to initiate litigation or administrative proceedings to enforce and/or defend its patent rights 
 which will be costly whether Kineta wins or loses;                                                              |

| • |     | Kineta may choose not to file a patent application in order to maintain certain trade secrets or know-how, and a third party may subsequently file a patent application covering such intellectual property; |

Such licenses may not be available in the future or may not be available on commercially reasonable terms, or at all, which could have a material adverse effect on Kineta’s business and financial condition. Kineta may rely on third parties from whom it licenses proprietary technology to file and prosecute patent applications and maintain patents and otherwise protect the intellectual property Kineta licenses from them. Kineta may have limited control over these activities or any other intellectual property that may be related to Kineta’s in-licensedintellectual property. For example, Kineta cannot be certain that such activities by these licensors will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. Kineta may have limited control over the manner in which its licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain
