Peer Group Issuers, Footnote

Independent Consultant; Peer Group and Benchmarking

The Compensation Committee has the authority to directly retain the services of independent consultants and other experts to assist in fulfilling its responsibilities. In August 2024 and October 2025, the Compensation Committee retained Aon to conduct a detailed assessment of the current executive compensation program to recommend any potential policy changes for fiscal year 2025 and 2026. The Compensation Committee assessed the independence of Aon pursuant to SEC rules and in accordance with Nasdaq listing standards, noting that Aon (i) did not have any relationships with the Company, our executive officers or our Compensation Committee members that would impair its independence, and (ii) does not provide any services to the Company other than advice to the Compensation Committee regarding executive officer and director compensation, and concluded that Aon is free from conflicts of interest and is independent.

In October 2025, the Compensation Committee approved a peer group of 22 companies proposed by Aon (the “Peer Group”). The Peer Group was chosen using various parameters, bearing in mind that some of the companies in the Peer Group meet some but not all of the below criteria:

Biotechnology with a focus on companies including artificial intelligence in drug discovery.
Phase I, Phase II and Phase III companies with preference towards AI enabled companies.
Target companies with a market capitalization below $100 million.
Target companies under 100 employees in anticipation of FYE 2025-26 headcount projections.
Preference was given to US-based companies, with a focus on companies headquartered in San Diego, CA or other life science hubs.

At the time the peer group was approved, we had a 30 day average market cap positioned at the 7th percentile of the peer group, as the peer group median equaled $62.6 million and our projected FYE 2025 headcount (20 employees) was positioned at the 31st percentile of the peer group; as the peer group median equaled 35, even though many companies are larger, they were chosen primarily for their business model, headcount, and stage of development rather than market cap alone. The approved peer group consisted of the following companies:

Agenus

  ​

  ​

Dyadic

  ​

  ​

Pyxis Oncology

Artiva Biotherapeutics

Gain Therapeutics

Rallybio

Assembly Biosciences

Lantern Pharma

Relmada Therapeutics

BioAtla

Lisata Therapeutics

Skye Bioscience

BullFrog AI

Matinas BioPharma

Spectral AI

CEL-SCI Corporation

MediciNova

Werewolf Therapeutics

Compugen

OmniAb

CytomX Therapeutics

Precision Biosciences

Aon provided an analysis of data derived from members of our Peer Group. The Compensation Committee used Aon’s analysis to help structure a competitive executive compensation program, position executive compensation by considering market data, and make individual compensation adjustments and decisions based on comparable positions at companies with which we compete for talent. While the Compensation Committee does not establish compensation levels solely based on a review of competitive data or benchmark to any particular level, it believes such data is a useful tool in its deliberations as our compensation policies and practices must be competitive in the marketplace for us to be able to attract, motivate and retain qualified executive officers. The Compensation Committee uses the peer group compensation data as one of several factors in determining appropriate compensation parameters for base salary, variable cash compensation and equity-based, long-term incentives. The Compensation Committee’s executive compensation decisions are made on a case-by-case basis, and specific benchmark results do not, in and of themselves, determine individual target compensation decisions.
