Resilience and adaptability are the cornerstones of sustainable growth. By embracing change, we strengthen our ability to meet challenges head-on, ensuring we continue to deliver value to our customers, support our employees, and make a positive impact in the communities we serve.MICHAEL DUFFYCEO & President, Petrosmith““A MESSAGE FROM THE CEO2024 was a year filled with unique challenges and opportunities for both our industry and the business at Petrosmith. Market fluctuations, shiing demands, and operational hurdles tested our resilience, while uncertainty shaped much of the year. From election-year impacts on demand and investment cycles, to supply chain disruptions and evolving energy needs, we navigated these obstacles while continuing to invest in what drives our business…our people. These challenges we face serve as a continued reminder of the need to invest and strengthen our business, while leveraging our core competencies to diversify the business and create sustainable growth opportunities across multiple markets. In the oil and gas industry, election years oen create unpredictability, influencing customer behavior and delaying investment decisions. This was especially true in 2024, as many customers pulled back on capital spending due to future uncertainty, resulting in a reduced demand overall, and an unsteady demand cycle. The second half of the year saw an increased demand compared to the first half, requiring swi operational adjustments and increased production capacity. To meet customer needs, we expanded our workforce, adding 50 new jobs and promoting 40 internal employees, including 18 advancing to lead or supervisory positions and 13 transitioning to new departments with greater responsibilities. This growth extended to key areas such as project management, engineering, sales, and quality assurance, enabling us to eiciently meet demand while maintaining quality and supporting the communities we serve. Operationally, 2024 was marked by significant enhancements to our business infrastructure. Petrosmith implemented an entirely new ERP system to help support our expanding business operations, streamlining financial management, improving eiciency and transparency, and enabling our teams to focus on driving operational success. Additionally, we implemented a new environmental policy and made strategic CAPEX investments in our production operations and the implementation of environmental sustainability practices such as rainwater collection systems to replenish hydrotest systems. These initiatives supported our eorts in an initial successful EcoVadis assessment and together, these investments and upgrades help to strengthen our long-term operational resilience and ensure we remain at the forefront of industry best practices. As the upstream energy sector sought to balance energy security with sustainability practices, Petrosmith saw remarkable growth in our TesselTM technology, which helps to eliminate fugitive methane emissions in upstream oil and gas production facilities. Demand for TesselTM units increased nearly 10-fold, signaling the industry’s commitment to cleaner, more responsible energy production. Petrosmith remains dedicated to accelerating this progress, investing in innovation and strategic partnerships to develop solutions that not only address today’s energy challenges but also promote a sustainable future. As I reflect on the past year, it is evident that 2024 was not only defined by the challenges we faced, but by our ability to adapt, persevere, and transform obstacles into opportunities. I am incredibly proud of our workforce’s resilience and ingenuity in overcoming operational hurdles. Their dedication has strengthened our foundation, improved eiciencies, and positioned us for continued success as embark on our mission to become a diversified supplier of infrastructure support products. Looking ahead, I am optimistic about the longer-term future as we continue to diversify. Our commitment to innovation, sustainability, and operational excellence will drive even greater progress, serving multiple markets. With this, we are pleased to present Petrosmith’s 2024 Business Responsibility Report, a testament to our resilience, innovation, and sustainable growth. Through this report, we share our achievements, lessons learned, and commitment to responsible business practices.

Through strategic investments in sustainable technologies and innovative processes, we prioritize resource eiciency, waste reduction, and environmental protection. Our initiatives include enhanced water systems, improved emissions control measures, and responsible materials management across our operations. By aligning our practices with industry best standards and environmental regulations, we are dedicated to safeguarding natural resources and fostering a more sustainable future.For the third consecutive year, Petrosmith measured our Scope 1 and 2 greenhouse gas (GHG) emissions footprint as part of our ongoing commitment to transparency and accountability in environmental performance. As part of this process, we also completed a comprehensive baseline emissions assessment, allowing us to better track year-over-year progress and identify areas for operational improvement. Our combined Scope 1 and 2 emissions increased by 14% in 2024, rising from 6,565 tCO₂e in 2023 to 7,497 tCO₂e. This is primarily attributed to an uptick in coated pipe production within our equipment segment, driven by customer demand for pipe with internal powder coating (IPC). The IPC process requires the use of a natural gas oven to cure the powder, resulting in elevated energy consumption and associated emissions. While this operational adjustment reflects our responsiveness to customer specifications and market demand, we recognize the environmental impact and are proactively exploring ways to reduce emissions in similar processes going forward. Our teams are evaluating energy-eicient alternatives, process optimization opportunities, and potential investments in lower-emission technologies to support our long-term goal of reducing operational GHG intensity across our facilities.

Electricity usage increased in 2024, largely driven by heightened fabrication activity and the continued growth of our Tessel™ product line. The number of Tessel™ units manufactured rose significantly, from 12 units in 2023 to approximately 60 units in 2024. These vessels are not only larger in scale but also require more extensive welding processes for spools and pipes, contributing to increased electrical demand. This rise in electricity consumption aligns with higher usage of welding consumables such as gas and wire, further supporting the correlation between increased production complexity and energy use. As we scale our operations to meet customer demand, we remain focused on identifying opportunities to improve energy eiciency across our manufacturing processes.

Liquid propane and natural gas, classified as Scope 1 stationary combustion sources, saw notable increases, particularly natural gas. This was due to a significant rise in powder coating processes within our equipment operations for pipe spools associated with ModFlex projects. Additionally, a third natural gas oven used for burn-out processes in our pipe yard was brought online for part of the year aer remaining inactive in 2023, further contributing to the increase in stationary combustion emissions. Diesel and gasoline, classified as Scope 1 mobile combustion sources, reflected fuel use from Petrosmith-owned and operated fleets and equipment across multiple locations. Diesel consumption, which includes usage from industrial and commercial equipment as well as vehicle fleets operating at our Fredonia, Mineral Wells, Abilene, and Midland locations, reduced slightly despite the launch of a fourth plug and abandonment (P&A) rig, as the new rig operated near an existing one, reducing travel requirements. Moreover, this rig was taken out of service from August through December, resulting in lower overall diesel consumption than might otherwise have been expected. Gasoline consumption saw a modest increase, primarily due to the support operations required for the fourth rig. This included increased activity from Petrosmith’s fleet of company-owned cars and light-duty trucks based in Abilene, along with additional crew and service vehicles such as mechanical trucks traveling to and from field locations. Although the rig itself had limited movement, additional crew trucks and service vehicles, including those operated by field mechanics, were active throughout the year. These trends in both stationary and mobile combustion sources reflect the variability of project-specific needs and underscore the importance of continuous monitoring and strategic planning to drive fuel eiciency and reduce Scope 1 emissions over time. 120,000110,000100,00090,00080,00070,00060,00050,00040,00030,00020,00010,0000Propane(Gallons)+68%+22%-11%+14%Natural Gas(Cu.

“At Petrosmith, we are committed to developing and delivering innovative solutions that reduce waste and adopt smarter resource management strategies. These efforts enable us to operate more efciently, support industry sustainability goals, and create lasting positive impacts for our stakeholders.”ENHANCING RESOURCE EFFICIENCYJOSE LUIS MALVICINOChief Financial Ofcer, PetrosmithWELLS PLUGGEDPREVENTING EMISSIONS THROUGH REMEDIATIONPlugging and Abandonment (P&A) services play a crucial role in employing advanced techniques to safely and eectively seal inactive wells, preventing the release of harmful emissions and protecting surrounding ecosystems. This essential process not only mitigates environmental risks by containing hydrocarbons and greenhouse gases but also safeguards freshwater aquifers from potential contamination.In 2024, Petrosmith plugged 189 wells, a 13% decrease since 2023. The decrease in plugged well count was primarily due to the low natural gas prices in the first half of 2024. During this period, many companies opted to delay plugging wells and instead put up bonds to conserve cash until natural gas prices improved. Petrosmith, which typically plugs gas-oriented wells because the salvage pipe quality is better than that of oil wells, was aected by this trend. Companies usually use the revenue from gas sales to fund the plugging of old wells they are obligated to plug. However, when gas prices are low, they lack the additional cash needed to cover the operating expenses (OPEX) associated with plugging wells. By putting up a bond, which costs significantly less than the actual cash required for plugging, they can delay the process, resulting in a decrease in well count for 2024.ENVIRONMENTAL COMPLIANCEPetrosmith complies with environmental regulations such as the Texas Waste Reduction Policy Act (WRPA) is a Title V permit holder for air emissions, and is subject to strict regulation and oversight. In 2024, Petrosmith successfully completed its Title V permit audit and renewal process. The permit was renewed without issue, as we remained fully compliant with all recordkeeping requirements and operated well below the emissions thresholds governed by the Title V program. We partner with a third-party environmental services firm, R2M, based in Lubbock, Texas, to support all of our TCEQ and EPA regulatory requirements. R2M assists with environmental calculations, data submissions, compliance reporting, and ongoing program management, including our recent Title V permit renewal.Additionally, at the end of 2023 and into early 2024, Petrosmith underwent a comprehensive Phase I Environmental Site Assessment conducted by Terracon. This assessment was a routine requirement as part of our ongoing relationship with PNC Bank, which provides our Asset-Based Lending (ABL) facility. Because the facility is secured in part by our real estate assets, the audit was necessary for the renewal process. We were pleased to receive a clean report with no Recognized Environmental Conditions (RECs), a strong validation from a respected national firm like Terracon.3002502001501005001842161892022 2023 2024About This Report Minimizing Environmental Impacts Advancing Social Responsibility Guiding Governance AppendixPETROSMITH: 2024 Business Responsibility Report16 1717

FY2023PRIORITIZING SAFETY & WELL-BEING Our commitment to safety goes beyond compliance — it’s deeply embedded in our culture, and we empower employees to take an active role in safety practices by fostering open communication, accountability, and teamwork. Through consistent training, clear protocols, and ongoing engagement, we ensure that safety remains a top priority in every aspect of our work. To strengthen this commitment, we partner with independent third-party experts who assess our health and safety performance across all business areas and provide valuable insights that allow us to refine processes, adopt best practices, and drive continuous improvement. By sharing these findings with our teams, we ensure consistent safety enhancements across our operations. In accordance with our Environmental, Health, and Safety (EHS) program, supervisors managing employees in areas involving hazardous materials or waste must provide detailed, site-specific training. This training includes hazard identification, PPE requirements, proper control procedures, and the location of key resources such as safety plans, chemical inventories, and Safety Data Sheets (SDS). Petrosmith is proud to report the eorts of our EHS team, safety committee, as well as all our employees have allowed us to achieve first-quartile performance for five consecutive years with regard to TRIR and LTIR metrics. In 2024, we proudly maintained our record of zero fatalities among employees and contractors, in addition to zero vehicle accidents, reinforcing our unwavering commitment to safety and the eectiveness of our proactive safety measures. *Unlike TRIR and LTIR, where lower rates indicate stronger performance, there is no OSHA benchmark for Near Miss Frequency Rate, and a higher rate can actually signal a healthier safety culture. In 2024, Petrosmith’s increased near miss rate reflects a deliberate and positive shi toward greater transparency and accountability. By encouraging proactive reporting, we are capturing a broader range of potential hazards before they result in incidents. This increase is an expected and welcomed outcome of our behavior-based safety approach, which focuses on recalibrating risk tolerance and empowering employees to recognize and report unsafe conditions early, ultimately strengthening our overall safety performance by fostering a proactive, rather than reactive, safety culture..82 .20 0Total Recordable Incident Rate3.6Near Miss Frequency RateLost Time Incident Rate (LTIR)Vehicle IncidentsTOTAL RECORDABLE INCIDENT RATENEAR MISS FREQUENCY RATE*0.500.450.400.350.300.250.200.150.100.050.00FY2022 FY2024LOST TIME INCIDENT RATEIn 2024, Petrosmith received the Texas Mutual Insurance Agency Platinum Award, which recognizes companies that go above and beyond to ensure employee safety by providing the resources necessary to protect their workforce from workplace hazards.2024 Texas Mutual Agency Platinum AwardFY2023FY2022 FY2024 FY2023 FY2024INTERNAL GOALS1.601.401.201.000.800.600.400.200.004.003.503.002.502.001.501.000.500.00INTERNAL GOALS3131About This Report Minimizing Environmental Impacts Advancing Social Responsibility Guiding Governance AppendixPETROSMITH: 2024 Business Responsibility Report30

INVESTING IN OUR PEOPLEAt Petrosmith, we understand that investing in our people goes beyond the workplace — it means supporting their well-being, security, and future. Petrosmith strives to provide our employees and their families with a comprehensive and valuable benefits package designed to meet the diverse needs of our employees and their families. To promote financial stability and work-life balance, we also provide retirement savings options, paid time o, and wellness programs.In 2024, 72% of our workforce enrolled in dental insurance, 69% in vision coverage, and 67% in medical insurance. By prioritizing employee well-being, we encourage our team to thrive both personally and professionally, strengthening our workforce and driving Petrosmith’s long-term success.We believe in empowering our employees through education. We oer tuition reimbursement for those pursuing higher education or continuing education credits to enhance their skills and advance their careers.HEARING CONSERVATION PROGRAMOur Hearing Conservation Program, enacted in 2023, protects our employees against potential eects of occupational noise exposure. This program was stood up in response to comprehensive third-party audit in 2021 that acted as a baseline for ongoing hearing conservation eorts. Our program closely follows the OSHA regulation 29 CFR 1910.95. In alignment with this standard, we evaluate the noise level in our employees’ work environments, provide adequate protective measures, implement controls, conduct audiometric testing, and keep records. During our tests, we use dosimeters to evaluate the thresholds of decibel exposure our employees experience during their shis. If the test indicates a dBA above 90, employees are required to wear hearing protection. To measure the eectiveness of our protocols, we conduct annual hearing health checkups to see if any major shis have occurred to our employees’ hearing health YoY. The test undertaken last year revealed no major shis in our employees’ hearing health. $21,000in tuition reimbursement committed to support eight employees in 20243333About This Report Minimizing Environmental Impacts Advancing Social Responsibility Guiding Governance AppendixPETROSMITH: 2024 Business Responsibility Report32

MOBILE BOOT PROGRAMinvested in the Mobile Boot Trust Footwear Programinvested in the Uniform Programinvested in the Prescription Glasses ProgramUNIFORM SERVICES & PRESCRIPTION GLASSESWe recognize that employee well-being is crucial to maintaining productivity and job satisfaction. An estimated 22% of lost time and work productivity is due to shoe discomfort, nearly double the amount of lost time caused by injuries. To address this issue, we have implemented theMobile Boot Truck Footwear Program to ensure that each employee receives a custom-fitted, brand-new pair of work boots annually. Employees can choose from over 15 brands and styles of work boots and insoles, guaranteeing they find the best fit for comfort and safety during their work.In 2024, we continued to prioritize employee well-being by providing uniform services that ensure our team members have access to clean, durable, and properly fitted work attire. This initiative not only enhances comfort and professionalism but also reinforces safety by ensuring employees are equipped with appropriate clothing for their roles. Additionally, we partnered with EyeMart Express to oer complimentary prescription safety glasses, enabling employees who require corrective lenses to perform their tasks safely and eectively without compromising vision or protection. $112,70 0+$319,500+$9,000In 2024, Petrosmith invested in employee appreciation by providing a year-end bonus totaling $105,000, distributed as a gesture of goodwill rather than being tied to specific performance metrics.We recognize and reward our employees for their hard work and dedication.

Each manager is provided with credits to award employees who go above and beyond.Employees who receive these credits can redeem them at the Petrosmith Cintas store to “purchase” branded items such as t-shirts, sweatshirts, coolers, polos, tumblers, and hats. The Petrosmith Swag Shop is more than just a reward system — it’s part of our broader initiative to boost employee engagement, foster pride in our team, and expand brand awareness within our workforce, community, and beyond.CELEBRATING EMPLOYEE EXCELLENCE$105,000in year-end bonuses allocated to employees in 2024In 2024, Petrosmith invested $30,500for employee gis and $12,100for swag shop purchases as part of the employee recognition program3535About This Report Minimizing Environmental Impacts Advancing Social Responsibility Guiding Governance AppendixPETROSMITH: 2024 Business Responsibility Report34

By promoting equality, embracing diverse backgrounds, and encouraging open dialogue, we cultivate a culture of collaboration and innovation. This commitment to inclusivity strengthens our workforce and drives Petrosmith’s continued growth and success.

In 2024, we conducted our inaugural assessment of hourly employees’ wages to evaluate pay equity and ensure alignment with our values. This assessment examined how wages vary by gender, tenure, and department, as well as how they compare to the local living wage standard. The U.S. oil and gas industry generally sees men earning approximately 17% more than their female counterparts. Upon comparison of our employees’ wages, adjusting by department and tenure, we found our female employees were paid an average of 2.5% more per hour. While this 2.5% dierence is considered statistically insignificant, it highlights Petrosmith as a champion for pay equity in an industry historically marked by wage disparities. By continuously monitoring wage data and maintaining our focus on equity, we are proud to be setting a standard for fair pay practices in the oil and gas industry. 60% of Employees Come from Diverse Backgrounds5% of Diverse Employees in Leadership Roles455 Total Employees14% of Workforce in Leadership Type Roles5% of Total Workforce are Female7% Veteran EmployeesAs part of our expanded Business Responsibility program, Petrosmith conducted a comprehensive assessment of our hourly employees’ wages against the local living wage standard. Paying a living wage is not only an ethical practice but has also proven to reduce turnover, improve retention, and enhance job satisfaction. Unlike the minimum wage, a living wage represents the income required for a worker and their family to meet essential needs, including food, healthcare, education, housing, and other critical expenses. According to the World Benchmark Alliance, only 4% of global companies currently meet this standard. In 2024, 82% of Petrosmith employees earned wages above the local living wage. As part of our commitment to supporting our employees both at work and in their daily lives, we aim to reduce the percentage of employees earning below the average living wage to 0% by 2027.OUR LIVING WAGE COMMITMENT 3939About This Report Minimizing Environmental Impacts Advancing Social Responsibility Guiding Governance AppendixPETROSMITH: 2024 Business Responsibility Report38
