STAK

What STAK does

STAK Inc. is a Nasdaq-listed (ticker: STAK) manufacturer of oilfield-specialized vehicles and equipment, founded in 2012 and headquartered at Building 11, 8th Floor, No. 6 Beitanghe East Road, Tianning District, Changzhou, Jiangsu, China. The company designs and builds more than 80 specialized vehicle models (oil production trucks, well repair trucks, fracturing trucks, well washing trucks, boiler trucks, well logging trucks, cementing trucks, rescue vehicles, liquid nitrogen pump trucks, and maintenance vehicles) and more than 30 specialized equipment models for well repair, well washing, fracturing, logging, and well completion operations. Its underlying technology integrates intelligent control features (four-way imaging, satellite positioning, anti-collision, speed-limit, remote data acquisition and monitoring, and visual-perception tubing defect detection) with domain-specific mechanical innovations such as high-temperature well washing, steam boost, and pressure relief induction systems for boiler trucks, supported by 79 granted patents and copyrights and 28 pending applications.

STAK's revenue model is primarily direct B2B hardware sales of specialized vehicles and capital equipment on a unit-pricing basis, with all quotations generated through an inquiry-based sales process (website form, email, or phone) supported by a 15-language website and explicit OEM/ODM custom-manufacturing services. The primary customer segment is oilfield services firms and oil mining operators in China. In May 2025 the company diversified into a four-model battery-electric New Energy Vehicle (NEV) line for oilfield logistics and construction, which generated approximately RMB 62.6 million (US$9.2 million) cumulatively through March 31, 2026. On June 8, 2026 STAK announced a memorandum of understanding to form a 60%-owned U.S. subsidiary (Delaware-incorporated, Texas-based operations) to commercialize a field-proven modular gas-to-electricity power generation system delivering up to 1.4 MW per ISO-compliant container, targeting AI data center operators in North America; this unit remains pre-revenue and subject to EPA certifications and state environmental permits. The company reported H1 FY2026 revenue of $19.2 million (up 13.41% year-over-year), net income of $1.8 million, and gross margin of 27.24% (down from 30.65%), and as of January 8, 2026 had a market capitalization of approximately $5.81 million following a 88.2% stock decline over the prior year.

Comparable to STAK's planned gas-to-electricity containerized product in distributed power for AI and energy-intensive users.
• XCMG: One of China's largest heavy equipment manufacturers with diversified specialty vehicle and machinery lines, including applications in oilfield and mining. Comparable to STAK as a broader Chinese specialty-vehicle platform, though XCMG's scale and product breadth are far larger.
• Caterpillar: Global heavy equipment and engine/genset manufacturer with extensive oilfield equipment exposure and modular power generation offerings. Comparable to STAK as a broad incumbent in both oilfield specialty vehicles and modular power generation, though at incomparably larger scale.
• SLB (Schlumberger): World's largest oilfield services company with comprehensive offerings across drilling, evaluation, production, and digital. Comparable to STAK as a broad incumbent across the upstream oilfield equipment value chain, though at vastly greater scale and geographic reach.
• Sany Heavy Industry: Large Chinese heavy equipment manufacturer with a growing oilfield-equipment and specialty-vehicle portfolio. Comparable as a much larger incumbent producing specialized industrial vehicles, though Sany's portfolio spans construction machinery far beyond oilfield.
• Halliburton: Global oilfield services and equipment giant whose product portfolio includes fracturing, cementing, well intervention, and digital oilfield solutions. Comparable to STAK as a broad incumbent in many of the same oilfield equipment categories (fracturing, cementing, well intervention).
