Explanatory Note

This Form 6-K/A amends the Form 6-K previously filed on August 21, 2025 for the purpose of disclosing the increase in the number of Ordinary Shares (as defined below) simultaneously with the adjustment to the exercise price of the Warrants (as defined below).

Warrant Adjustment

On May 1, 2025, ADS-TEC ENERGY PLC, a public limited company incorporated under the laws of Ireland (the “Company”) ads-tec Energy GmbH, a limited liability company under German law (“GermanCo”), and ads-tec Energy, Inc., a Delaware corporation (the “ADSE US” and together with GermanCo, the “Subsidiary Grantors”), entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors (the “Purchasers”), pursuant to which the Company agreed to issue (i) senior secured convertible notes in the aggregate original principal amount of $53,763,441 (the “Notes”) and (ii) warrants (the “Warrants”) to purchase up to an aggregate of 1,116,072 ordinary shares, nominal value of $0.0001 per share (“Ordinary Shares”). The Notes, Warrants and Ordinary Shares issuable upon conversion of the Notes and the exercise of the Warrants were issued pursuant to the Company’s effective shelf registration statement on Form F-3 (File No. 333-284850) (the “Registration Statement”) and the related base prospectus included in the Registration Statement, as supplemented by a prospectus supplement filed on May 1, 2025. 

Pursuant to Section 2(d) of the Warrants, if on the seventy-fifth (75^th) trading day following May 1, 2025 (i.e., August 19, 2025, the “Adjustment Date”), the exercise price then in effect is greater than 95% of the lowest VWAP of the Ordinary Shares on any trading day during the ten (10) consecutive trading day period ending and including the trading day immediately preceding the Adjustment Date (the “Market Price”), the exercise price shall automatically lower to the Market Price. In accordance therewith, on August 20, 2025, the Company notified the holders of the Warrants of an adjustment to the exercise price of the Warrants from $16.88 per share to $10.31 per share (the “Adjustment Price”).

Simultaneously with the adjustment to the exercise price of the Warrants, pursuant to Section 2(c) of the Warrants, the number of Ordinary Shares that may be subscribed for upon exercise of the Warrants has been increased by an additional 711,212 Ordinary Shares from 1,116,072 Ordinary Shares to 1,827,284 Ordinary Shares.

The foregoing descriptions of the Purchase Agreement and the Warrants are not complete and are subject to and qualified in their entirety by reference to the full text of the SPA and the Warrants, respectively, copies of which are attached as Exhibits 10.1 and 4.1 hereto, respectively, and are incorporated herein by reference.

Forward-Looking Statements

This Form 6-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The Company’s actual results may differ from its expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believe,” “hope,” “predict,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include the Company’s expectations with respect to future performance and involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside the Company’s control and are difficult to predict. Factors that may cause such differences include but are not limited to risks and uncertainties incorporated by reference under “Risk Factors” in the Company’s Form 20-F (SEC File No. 001-41188) filed with the SEC on May 12, 2025 and in the Company’s other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based.
