BioLargo, Inc. disclosed that its long‑standing license and manufacturing relationship with Pooph Inc. has broken down, and it has issued notice revoking Pooph’s license and terminating the License Agreement with 150 days’ notice after Pooph failed to pay agreed royalties and product invoices. Pooph has stated it will stop ordering from BioLargo, pursue its own formula for Pooph‑branded products, and terminate the Preferred Master Manufacturing Agreement, which BioLargo disputes, citing its contractual right to withhold product when payment terms were not met.
BioLargo also reported that a $3,486,000 note receivable tied to Pooph royalties and product invoices on its June 30, 2025 balance sheet may need to be written down, and management expects any impairment of this asset to be substantial, signaling a potentially significant financial hit related to this customer relationship.
