Insights

Capital structure analyst

ADS-TEC Energy eliminated secured convertible notes but reduced cash.

ADS-TEC Energy repaid its Senior Secured Convertible Notes due 2028 by paying $27.9 million in cash on November 19, 2025. This fully satisfies the notes and removes the associated liens and other security, simplifying the capital structure and removing a secured creditor from the balance sheet.

Following the transaction, the company reports cash and cash equivalents of about $4.5 million and availability of about $7.5 million on its revolving credit facility, with $2.5 million already drawn. This indicates lower gross debt from the redeemed notes but also a reduced cash position, so liquidity will depend on operating cash flows and remaining credit availability.

As of November 19, 2025, there were 60,122,536 Ordinary Shares outstanding, while warrants issued under the May 1, 2025 Securities Purchase Agreement remain outstanding and could influence future equity issuance if exercised.
