Picture a van equipped with hydrogen generators zipping to garages and fleets, blasting away engine carbon without disassembly—that's the disruptive edge HHO Carbon Clean Systems brings to automotive services since 2020. In this nascent market for on-site diesel and gas cleanings, the FDD hints at operational realities through termination counts and a lone SBA loan record, but skips Item 19 earnings disclosure. Does this Paducah, KY-based system's recent contraction signal turbulence or a ground-floor entry into hydrogen tech's rise?
Item 7 lays out the financial entry: initial investment spans $108,380 to $185,330, kicked off by a $44,900 franchise fee for proprietary HHO equipment, territory rights, and training. Ongoing bites include an 8% base royalty (tiered down to 6% potentially), 2% brand fund, and a flat $275 monthly technology fee—stacking up to 10%+ of gross sales plus fixed costs that could pinch slim margins in a mobile model. Without Item 19, you're blind to average unit volumes or profits, a glaring gap forcing reliance on the franchisor's projected 4 new units amid just 14 active franchises and 1 corporate spot; that absence matters hugely for modeling ROI in a service hungry for validation.
System metrics raise flags: locations shrank from 15 in 2023 to 14 in 2024 (-7% growth), with 4 terminations signaling possible early attrition in this five-year-old network. One SBA loan averaging $150,000 suggests financing hurdles or scale attempts, but limited data tempers enthusiasm. For a buyer eyeing this eco-angle in engine maintenance, probe FDD Items 20/21 for closure trends and renewal rates, plus vendor-locked supplies costs—uncover if hydrogen hype translates to territorial cash flow before committing.
