Ultra Clean Holdings, Inc. announced that Harjinder Bajwa has departed the company effective January 25, 2026, and that Robert Wunar has been appointed Chief Operating Officer effective March 23, 2026. Mr. Wunar brings more than 30 years of deep operations and supply chain leadership within the semiconductor capital equipment industry. Most recently, he served as the COO/Managing Director of Business Unit Operations at Applied Materials, Inc., where he was accountable for revenue, profitability, and end-to-end supply and demand execution for numerous product lines. His experience spans global manufacturing, cost optimization, cycletime reduction, supply-chain resilience, and scaling operations to support major industry ramps. Additionally, Mr. Wunar’s customer-centric, peoplefocused leadership style will enhance UCT’s strategic partnerships with key customers. “Robert is a proven operations leader with a deep understanding of what it takes to execute at scale in our industry,” said James Xiao, CEO. “His experience driving operational excellence, combined with his focus on speed and agility, will be instrumental as we prepare UCT for the next semiconductor ramp. Robert’s ability to translate strategy into disciplined execution across global operations will help ensure we are ready to support our customers with the quality, responsiveness, reliability and trust they expect.” Throughout his career, Mr. Wunar has demonstrated a strong track record of driving gross-margin improvement, improving on-time delivery, reducing manufacturing cycle times, and building global manufacturing and supplier capabilities to support growth. He has led operations across the full product lifecycle—from R&D and new product introduction through high-volume manufacturing—while maintaining a strong focus on quality, execution discipline, and customer outcomes. Mr. Wunar holds a Bachelor of Science degree in Electronics Engineering Technology from DeVry Institute of Technology and has spent his career building and leading high-performance, crossfunctional teams in complex manufacturing environments. “I would like to thank Harjinder for his many contributions to UCT,” continued James Xiao, CEO. “During his tenure, Harjinder played an important role in strengthening our operational foundation and positioning UCT for the future. We are grateful for his leadership and wish him continued success in his next chapter.” Ultra Clean Appoints Robert Wunar as Chief Operating Officer Sazini will bring a wealth of global development and nonprofit expertise to lead Village Enterprise’s efforts in lifting families out of extreme poverty through entrepreneurship The Board of Directors at Village Enterprise is pleased to announce the appointment of Sazini Mojapelo as its next Chief Executive Officer. Sazini joins Village Enterprise from the International Finance Corporation (IFC), bringing an invaluable combination of global development, corporate, and nonprofit sector experience to Village Enterprise’s mission to lift families out of extreme poverty through entrepreneurship, innovation, and collective action. Sazini will be Village Enterprise’s first Africa-based CEO, beginning February 17, 2026. The leadership transition reflects Village Enterprise’s belief in the power of locally driven solutions to end extreme poverty in rural Africa. With 94% of its staff based in Africa, Village Enterprise’s leadership will now be closer to the communities it serves. As CEO, Sazini will lead the team from Nairobi, Kenya, guiding the organization through a shifting global aid landscape and strengthening partnerships with governments and funders to drive long-term, sustainable impact. Sazini replaces Dianne Calvi, who is stepping down as CEO after 15 years of growth and impact at Village Enterprise. Dianne initiated and announced her transition in June as part of her commitment to advancing African-led leadership at Village Enterprise. Sazini’s experience spans both the corporate and nonprofit sectors, having founded and led Hand in Hand Southern Africa, a regional NGO that alleviates poverty through job creation. She joins from the International Finance Corporation (IFC, a member of the World Bank Group) where she was the Global Gender GBV Lead, and she also previously held leadership roles in the corporate sector. Her deep understanding of corporate and multilateral funding, and her vision for how Village Enterprise can engage more effectively in these areas, will be instrumental as the organization’s impact continues to grow across Africa. As Village Enterprise’s impact has expanded to 10 countries in Africa and with bold new partnerships with governments, as well as global and local nonprofits, Sazini’s appointment comes at a critical time to build on this momentum and accelerate efforts to alleviate poverty through Village Enterprise’s proven poverty graduation approach. Bruce Sewell, Board Chair at Village Enterprise, said: “The Board and I are delighted to welcome Sazini to Village Enterprise. Her authentic, purpose-driven approach and commitment to servant leadership embody the values at the heart of our organization. She brings extensive experience across global development and nonprofit leadership, combined with the energy and ambition to guide Village Enterprise into a new phase of impact and scale.” Sazini Mojapelo said: “It is an honor to join Village Enterprise and to build on Dianne’s remarkable legacy. I look forward to working alongside our dedicated team and partners to lead the organization into our next chapter—deepening collaboration, strengthening impact, and expanding opportunity for the families we serve across rural Africa.” Dianne Calvi said: “This transition reflects a vision Village Enterprise and I have been building toward for many years—for the organization’s next CEO to be based in Africa. I am thrilled that Sazini Mojapelo will lead Village Enterprise into the future.”
