Impact at Syneos Health

Syneos Health creates and maintains an inclusive workplace culture by building inclusion into how we lead, how our offices are designed and how our colleagues connect. We support this through global policies, mandatory onboarding and annual training, including our Code of Business Conduct and Ethics and anti-discrimination and anti-harassment training, reinforced by leadership accountability, non-retaliation protections and reporting mechanisms.

Syneos Health supports employee development through role-specific training for new and existing colleagues, practical leadership development resources aligned with its Everyone Is a Leader framework, and a tech-enabled mentoring program. Career growth is further supported through a structured performance management process with goal setting, regular check-ins, ongoing coaching and year-end performance reviews.

Syneos Health supports employee safety, health and well-being through strong safety planning, real-time crisis support and expanded well-being and assistance programs. Our Health and Safety program is integrated within Corporate Security and Business Continuity, while our global Employee Assistance Program provides free, confidential access to counseling, coaching and everyday support.

Syneos Health operates responsibly, guided by ethics and integrity in everything we do. Our Code of Business Conduct and Ethics establishes clear expectations for ethical behavior and applies to all colleagues, officers and members of the Company’s governance bodies. It is supported by policies, business rules and procedures that address key risk areas, including anti-bribery and anti-corruption, conflicts of interest, data privacy, responsible marketing and interactions with healthcare professionals.

Syneos Health upholds high-quality data collection principles and focuses on patient safety through efficient, ethical and compliant clinical trial execution and site management. Our processes are supported by internal controls to verify that participant safety, rights and data integrity are consistently upheld and safeguarded, including informed consent procedures, ongoing safety surveillance and study data that are accurately recorded, verified and retained to support data integrity and inspection readiness.

Syneos Health’s GHG decarbonization targets were approved by the Science Based Targets initiative (SBTi) in 2025, confirming alignment with the latest climate science and the goals of the Paris Agreement. We are targeting a 42% absolute reduction in Scope 1 and 2 emissions and a 25% absolute reduction in selected Scope 3 emissions by 2030, from a 2023 baseline. Progress will be monitored through a Science-Based Targets Working Group, established as a subcommittee of the Impact Committee.

Syneos Health works with industry peers to better understand and reduce emissions associated with clinical trials. In 2025, we piloted the industry Low Carbon Clinical Trials carbon calculator to gain greater visibility into key emissions drivers and identify opportunities for reduction. We also added sustainability-related questions to our site registration process via StudyEngage to improve visibility into site-level practices. Across our operations, we focus on office energy efficiency, renewable electricity, lower-emission fleet options, driving-efficiency training and smarter routing tools.

Syneos Health prepares its greenhouse gas emissions inventory in accordance with the GHG Protocol Corporate Standard and uses technology to support consistent, comparable and decision-useful emissions data. We participate in external environmental disclosure frameworks to benchmark our performance and strengthen transparency, including CDP Climate Change and the Supplier Engagement Assessment. To better understand indirect emissions, we conducted a Scope 3 relevancy assessment and invested in a new tool to more accurately track business travel emissions by project, business unit and geography.
