STAK Inc. (the "Company" or "STAK") (Nasdaq: STAK), a fast-growing company specializing in the research, development, manufacturing, and sale of oilfield-specialized production and maintenance equipment, today announced the rapid scale-up of its new energy vehicle ("NEV") business, driven by a broadening product lineup and a growing portfolio of patents and software copyrights during the second half of 2025 and the first quarter of 2026.

The Company began exploring NEV-related business opportunities in May 2025 through limited initial deployments and preliminary commercialization activities. During the initial launch phase from May 1, 2025 through June 30, 2025, the Company generated approximately RMB2.8 million (approximately US$0.4 million) in NEV-related revenue, which primarily reflected early-stage market testing and customer onboarding efforts. Beginning in the second half of 2025, customer demand and commercialization activities expanded significantly, and the Company's NEV-related business generated approximately RMB62.6 million (approximately US$9.2 million) in cumulative revenues for the nine months ended March 31, 2026. The substantial increase in revenue contribution over a relatively short commercialization cycle reflects growing market acceptance and the scalability of the Company's NEV business strategy.

Alongside strong revenue growth, the Company continues to expand its NEV product portfolio with the introduction of more specialized vehicles. STAK currently markets four battery-electric models designed primarily for oilfield logistics and broader construction applications. These vehicles feature zero-emission operation, lower total cost of ownership, enhanced safety, and improved user experience, aiming to align with customers' increasing environmental, social, and governance ("ESG") requirements.
