Acorn (through OmniMetrix) has meaningful concentration in a single customer, the party to its 'Material Contract' — a national cell phone provider. That customer represented approximately 42% of accounts receivable at December 31, 2025 (more than 40% of total outstanding receivables), and hardware sales under the Material Contract were $2,293,000 in fiscal 2025 (about 20% of the company's $11,478,000 total revenue). Since inception through Q3 2025 the contract had generated roughly $4.2 million ($3.9M hardware plus $0.343M monitoring). Outside this contract, credit risk on trade receivables is generally diversified across a large number of customers and dealers, and the company reports greater-than-90% annual monitoring renewal rates.
