BrainChip Holdings Ltd has released its Quarterly Activities Report for the quarter ending September 2025. The company ended the quarter with a cash balance of $13.9M, compared to $13.5M in the prior quarter. Cash inflows from customers in the current quarter were lower at $0.3M, compared to $1.4M in the prior quarter, due to higher engineering revenues earned from 3 customers in the prior quarter. Total payments to suppliers and employees were higher at $5.2M, compared to $4.4M in the prior quarter, due to increased payroll costs, contractor fees, and corporate costs. The company continued its collaboration with multiple high-quality companies, including the advancement of a chip supply agreement with the Defense & Intelligence business unit of Parsons Corporation. BrainChip also continued to expand its global intellectual property portfolio, which now comprises 57 issued and pending patents across the United States, Europe, and APAC regions. Post the September 2025 quarter, the company announced the decision to move the AKD1500 from a reference design to volume production, driven by strong customer engagement across various target markets.

BrainChip's decision to move the AKD1500 into volume production underscores the company's confidence in the market opportunity and the strength of customer demand. This milestone, combined with strategic agreements like Parsons and expanded distribution through DigiKey, positions BrainChip for scalable revenue growth.
