Summary

  • Zone Frontier closed the sale of its aqueous-ozone cleaning-products business for a $3.35 million promissory note, scheduled across three payments over 18 months.
  • The note ranks behind future institutional borrowing, while an IP lien can be released after a qualifying $3 million financing and specified payments; Zone kept its data-centre interests, including a 99% capital interest in a West Texas joint venture.

Zone Frontier’s October pivot came with a payment calendar, not a bank balance. On 7 October, the company completed the sale of its legacy cleaning-products business to Sanzonate Holdings. The buyer delivered a secured, non-convertible promissory note for $3.35 million as the purchase price. The deal shifted the operating business; the collection job stayed with Zone.

The note pays 6% annual interest. Principal falls due in three steps: $300,000 six months after closing, $850,000 at month 12, then $2.2 million at month 18, with accrued interest. The next scheduled principal date is 7 April 2027. Those dates turn a completed disposal into a series of future credit checkpoints.

The price has a queue

The $3.35 million face amount sits above a stack of conditions. The note is subordinated to the buyer’s borrowed money from banks, commercial finance companies and other institutional lenders. If Sanzonate takes senior financing, those lenders stand ahead of Zone for payment and lien priority.

Zone does hold security: a first-priority interest in the intellectual property transferred with the business, subject to the stated subordination. That gives the seller a claim over patents, marks and other transferred IP while the note remains outstanding. It also makes the collateral part of the buyer’s financing plan.

The lien can end in two ways. Full repayment releases it. Earlier release is available if Sanzonate raises at least $3 million in equity or debt after closing, pays the first $300,000 principal installment and any first earnout then due, and has no default or unpaid earnout outstanding. A capital raise can therefore make the buyer more financeable and move the IP out of the collateral pool, while the later scheduled principal remains to be collected.

Future valuations set the extra price

The deal adds upside tied to Sanzonate’s financing rather than operating sales. A bona fide equity round at a pre-money valuation of $10 million triggers a $500,000 earnout. At $17.5 million, another $750,000 becomes due; at $25 million, a further $1 million. Each threshold builds on the one before it. The earnout period runs until the later of 18 months after closing or termination of the note.

Zone also received a 5% membership interest in Sanzonate at closing. A qualifying $25 million equity financing brings another 2% interest. The company’s potential proceeds therefore depend on three separate things: scheduled debt service, financing rounds that clear valuation thresholds, and the value of its minority stake in the buyer.

Those instruments have different clocks. Principal has fixed due dates. The earnout requires a qualifying equity financing. The extra units require the highest valuation threshold. The 5% stake exists now, but its cash value depends on the buyer’s future capital structure and performance. A $3.35 million note is a face amount; collection takes place over time.

The related-party page is in the filing

Sanzonate is controlled by Clayton Adams, a Zone board member and former chief executive. Adams had held an option to buy the cleaning-products business and exercised it through Sanzonate at closing. Zone’s filing says the disinterested directors approved the transaction after receiving a fairness opinion; Adams did not take part in their discussion or vote.

That disclosure matters because the buyer and seller were not strangers across a conference table. The filing names the relationship and the process used to review it. The commercial test now is more ordinary and more concrete: whether the buyer meets the note schedule, whether a financing round triggers the contingent payments, and whether the IP collateral stays in place until the agreement’s release conditions are met.

Zone kept the AI assets

The October filing says Zone retained all of its data-centre and AI-infrastructure interests. It names a 79% membership interest in the joint venture developing a Minnesota campus and a 99% capital interest in the joint venture developing the West Texas campus, together with related contracts. After the legacy disposals, the company said its operations consist of data centres and AI infrastructure.

Those percentages describe Zone’s interests in the two entities. The filing gives no live-power figure, contracted capacity, energized date or campus revenue. The old cleaning business had a signed buyer and a closing date. The new strategy still has its own construction and financing milestones.

The disposition separates those ledgers. Zone has moved the ozone business to a new owner and kept the infrastructure stakes. In between sits a receivable whose seniority can fall behind future lenders, collateral that may leave before the note is fully repaid, earnouts waiting for valuation thresholds and a minority stake in the buyer. The first scheduled principal installment arrives on 7 April. That is the next date when the pivot starts sending cash back.
