They review every number, stay engaged with the details, and have empowered us to make continuous safety improvements a top priority. This has been a major driving factor in building a culture of safety throughout the organization.” Keith Dares Vice President, Operations, Canada Safety doesn’t happen by chance—it results from years of dedication to continuous improvement. The GTE management team has worked to embed safety into the Company culture, recognizing that it is as much about people as it is about following processes. As GTE grows across Canada, Colombia, and Ecuador, it brings a consistent approach—grounded in core values and adapted to the specific needs of each region. Over the past three years, GTE has completed 27.8 million consecutive work hours without a Lost Time Incident, placing the Company in the top quartile for performance across its operating regions, despite the complexity of its drilling and exploration projects in remote areas. This strong record reflects GTE’s deep-rooted safety culture, where every employee takes responsibility for maintaining a workplace to ensure everyone gets home safely. 27.8 M WORK HOURS WITHOUT AN LTI 6,338 SAFETY INSPECTIONS 448 EMERGENCY SIMULATIONS38 2024 SUSTAINABILITY REPORT ~28 M WORKER HOURS WITHOUT RECORDING AN LTI *Incidents per 200,000 work hours.

In Colombia and Ecuador, GTE proactively strengthens its HSE (Health, Safety and Environment) management system, aligning with International Oil and Gas Producers (IOGP) and the Occupational Safety and Health Administration (OSHA) international standards while maintaining country-specific reporting. This commitment has built a strong safety culture, reinforced through recognition in town halls, structured training programs for new and long-standing employees and contractors, and an emphasis on risk assessment and management.

Safety remains a top priority as activity increases in Ecuador, with more wells and extensive road travel. GTE applies the team-based safety approach developed in Colombia, ensuring that safety culture extends beyond Health and Safety (HS) specialists and becomes ingrained in daily operations. HUMAN SAFETY EVOLUTION TRAINING GTE’s Human Safety Evolution Training is an in-house program designed to equip first-line managers with the skills to integrate HSE principles into their daily decision-making. This 6-month course combines virtual and in-person sessions, developing independent thinking and leadership in workplace safety, and empowering first-line managers to be able to make safety decisions rather than relying on dedicated safety personnel. The training unfolds in four key phases, each reinforcing discussion, reflection, and practical application. The program has delivered measurable improvements in HS scores, decision- making, and communication, strengthening GTE’s safety culture and embedding safety into leadership at all levels. It’s gratifying to see workers truly understand the importance of safety—not just as a corporate requirement, but as a fundamental part of their daily lives. Diego Arroyo HS Coordinator402024 SUSTAINABILITY REPORT CONVERSATION WITH ASHLEY JOANNA, HS PROFESSIONAL, ACORDIONERO Q: How did you first get involved in Health and Safety work? ASHLEY: I started out working on environmental projects during my internship but during the pandemic, there was a need for more support in HSE. That’s when I was introduced to Misión vida, and it completely changed my perspective. I quickly realized that health and safety could be so much more than just compliance—it could be about people, behaviour, and values. Q: What makes the Misión Vida approach so different from traditional safety programs? ASHLEY: Many companies focus heavily on systems, rules, and documentation. Misión vida is built on the idea that safety isn’t just about rules—it’s about changing behaviour through understanding and connection. When people understand why something matters, they’re more likely to take ownership, leading to better results. Q: Can you share an example of how that plays out on the ground? ASHLEY: We use all of our safety tools—like work permits, audits, and walkarounds, etc.—as opportunities to have real conversations. In the field, I often ask questions to help people identify risks on their own. That way, they’re building their critical thinking skills around safety. My goal is to mentor people so they can keep themselves and their colleagues safe, whether I’m there or not. Q: What impact does that approach have on your team? ASHLEY: It completely changes the dynamic. People feel seen and supported, not policed. I’ve told my boss before that I’m so happy with the work the team is doing, I sometimes feel like I’m not even needed! Of course, there are always situations we can learn from. But the mindset of continuous improvement is embedded into how we work. Q: What role does training play in all this? ASHLEY: It’s huge. GTE invests in us constantly. I was tested and trained for this role, and the learning never stops. That’s part of why this model works—because everyone is growing together. And when people feel capable and empowered, they’re much more likely to care about doing things the right way.

GTE complies with all applicable healthcare legislation and provides coverage for essential healthcare services to support employees and their families and emphasizes the role of workplace culture in promoting healthier lifestyles. To support healthy choices, the Company maintains an environment that encourages informed, positive decision-making. MONTHLY AVERAGES OF DAILY RISK CONTROLS FINISHING STRONG WITH FAMILY SAFETY MONTH December is critical for workplace safety, particularly in industries where accident rates tend to rise during the holiday season. To reinforce awareness and safe decision-making in its Colombia and Ecuador operations, thousands of workers participated in GTE’s Family Safety month. This six-week program of interactive activities, workshops, and crossfunctional learning keeps safety at the forefront—both on and off the job—so employees can enjoy the holiday season safely. ROAD SAFETY A Critical Priority Gran Tierra has registered approximately 1,500 transport drivers, making road safety a top priority with hundreds of trips undertaken daily. Transporting workers, equipment, and crude oil presents unique challenges, particularly in Colombia and Ecuador, where infrastructure and traffic conditions differ significantly from Western Canada. GTE’s Driving Plan follows the International Association of Oil & Gas Producers (IOGP) road safety framework, ensuring transport companies’ adherence to high safety standards. The Company also focuses on high-risk areas, particularly in Colombia, where 14 people lose their lives in motorcycle collisions every day, according to the country’s National Road Safety Agency.42 2024 SUSTAINABILITY REPORT BRINGING SAFE DRINKING WATER TO RURAL COLOMBIA In remote villages of Putumayo, Colombia, where government support is limited, access to clean water remains a persistent challenge, exposing families to waterborne diseases and other health risks. To help close this gap, GTE partnered with the international NGO Ayuda en Acción to launch the Water for Communities initiative in October 2024. The project will install a new water treatment system to ensure safe water access to thousands of residents across ten villages along the Puerto vega–Teteyé corridor. Additionally, a community-based water laboratory and training centre will be established to help residents learn how to manage and preserve water resources sustainably. As implementation begins in 2025, a central focus will be on training local residents to maintain the systems, ensuring long-term access to safe drinking water. This initiative complements an aqueduct system, also funded by the Company, through Colombia’s Works for Taxes program, which will bring potable water to another 1,300 residents in rural areas near Puerto Asís. STEWARDING THE ENVIRONMENT HEALTH AND SAFETY RESPECTING HUMAN RIGHTS INVESTING IN COMMUNITIES ENGAGING OUR NEIGHBOURS RESPONSIBLE GOVERNANCE INTRODUCTION ECONOMIC DEVELOPMENTHEALTHAND SAFETY43 TRANSFORMING RESIDUAL WASTEWATER INTO BIOGAS In many rural Colombian villages, untreated wastewater flows through open sewers, creating serious health and environmental risks—especially during the rainy season. At the same time, limited access to propane forces many households to rely on firewood, contributing to deforestation, air pollution, and causing significant adverse health effects. To tackle these dual challenges, GTE partnered with Antonio Nariño University to install 13 residential-scale anaerobic biodigesters in the Putumayo villages of Carmelita, Puerto Vega, and Remolinos. These systems treat wastewater organically and produce biogas for nearly 40 households and a school, eliminating open sewage while providing energy that can be used for cooking. This initiative, which satisfies Colombia’s requirement that 1% of project budgets be invested into environmental initiatives, demonstrates how thoughtful design can create lasting environmental, social, and economic impact. Encouraged by the project's success, plans for expansion to additional municipalities are underway. Before the project, some of these homes were abandoned due to contamination. Wastewater seeped into water wells, vermin overran the area, and the air was unbearable. Now, the water is clean, the smells are gone, and families have returned.
