Zone Frontier Sells Legacy Cleaning Products Business, Eliminating Approximately $3 Million in Annual Cash Burn While Retaining Significant Potential Upside

• Completes Zone's transformation into a pure-play AI infrastructure developer
• Ends approximately $3 million annual cash burn and preserves capital for AI infrastructure platform
• $3.35 million secured promissory note at 6% interest, significantly above an independent valuation of the business
• Up to $2.25 million in additional cash earnout payments tied to the buyer's future equity financings
• 5% equity interest in the buyer at closing with tag-along rights

HOUSTON, Oct. 8, 2026 /PRNewswire/ -- Zone Frontier Inc. (NYSE AMERICAN: ZONE) (the "Company" or "Zone Frontier") today announced the sale of its legacy aqueous ozone cleaning products business, including its wholly owned subsidiary CleanCore Global Limited, to Sanzonate Holdings LLC ("Sanzonate"), an entity controlled by Clayton Adams, the Company's former Chief Executive Officer and current board member. 

This legacy business consumed approximately $3 million of cash per year, lost $18 million in FY26, and required management time and attention that Zone is now directing entirely toward power-enabled compute campuses for AI customers across rural and industrial America. Additionally, the Company previously announced in July the sale of all remaining digital assets for approximately $33 million, and closure of its Treasury segment, which lost $156 million last year. With these sales, Zone stops funding those losses, keeps the vast majority of the cash it had previously set aside for the business, and retains several ways to benefit if the business succeeds under new ownership.

The consideration is well above the independent value of the business. A fairness opinion delivered to the Company's Board of Directors by Newbridge Securities Corporation valued the legacy business, excluding cash, at approximately $1.72 million. The $3.35 million face amount of the note significantly exceeds that valuation. If all earnout milestones are achieved, total potential cash payments to Zone would be approximately $5.6 million, before counting the retained equity.

"The CleanCore business has promising technology, but the business does not fit our core strategy anymore. This sale eliminates an ongoing cash drain that pulled management and Board attention away from our core AI infrastructure strategy. This transaction completes our transition into critical AI infrastructure as Zone Frontier," said Tyler Hassen, Chief Executive Officer of Zone Frontier. "We also receive a secured note with a face value significantly greater than the independent valuation of the business, and an equity stake in a team that is helping to shape the future of chemical free cleaning. If Sanzonate succeeds, our shareholders share in that success. Meanwhile, our capital and our focus are fully on building AI infrastructure."

Transaction Terms

• Secured promissory note. Sanzonate issued Zone a $3.35 million non-convertible promissory note bearing 6% annual interest, payable in installments of $300,000 at six months, $850,000 at twelve months and $2,200,000 at eighteen months, plus accrued interest.
• Security interest. The note is secured by a first-priority lien on the intellectual property transferred in the transaction. The lien remains in place until the note is repaid and may be released earlier only if Sanzonate raises at least $3.0 million in new capital, has made its first $300,000 principal payment, and is not in default under the note or behind on any earnout payment. The note and lien may be subordinate to future institutional senior debt of Sanzonate.
• Earnout payments. Zone is entitled to up to $2.25 million in additional cash payments if Sanzonate completes equity financings at specified pre-money valuations: $500,000 at $10 million or more, an additional $750,000 at $17.5 million, and a further $1.0 million at $25 million.     
• Retained equity. Zone received a 5% membership interest in Sanzonate at closing. Zone has tag-along rights on sales by Sanzonate's majority holders.
• Other terms. Zone transferred approximately $844,000 of cash to Sanzonate with the business and agreed to a three-year non-compete covering cleaning products.
• Ongoing CleanCore operating losses. Any future losses by the CleanCore business will be funded by new ownership.

The transaction was approved by the Company's independent directors following receipt of a fairness opinion from Newbridge Securities Corporation. Because Mr. Adams is a current member of the Company's Board of Directors and controls Sanzonate, the transaction was reviewed and negotiated as a related party transaction, but at arm's length terms. Mr. Adams recused himself from all Board deliberations and did not participate in the evaluation of the transaction or any negotiations on behalf of the Company. Additional information will be included in a Current Report on Form 8-K to be filed with the Securities and Exchange Commission ("SEC").
