Innventure (NASDAQ: INV) unit raises $40M as debentures shrink sharply

Rhea-AI Filing Summary

Innventure, Inc. filed a prospectus supplement that incorporates two recent current reports. Its subsidiary, Accelsius Holdings LLC, closed a new funding round by issuing Series B-1 units to Legrand DPC, LLC and Johnson Controls, Inc. for approximately $40 million, following an earlier October 2025 Series B-1 investment of about $25 million from Johnson Controls. Accelsius plans to use the new capital, after expenses, for general company purposes.

The Series B-1 units are convertible into Accelsius Class A common units at an initial issue and conversion price of $36.4877 per unit and carry customary investor protections. In connection with the closing, Accelsius amended its operating agreement to add Legrand as a member, expand the board to eight directors, grant Legrand one board seat with veto rights over certain major actions, and provide Legrand (and also Johnson Controls) with customary preemptive, information, and registration rights. Innventure also reported that Accelsius’ $40 million funding was based on a valuation of approximately $665 million and that the balance on its convertible debentures with Yorkville had decreased to about $6 million as of January 12, 2026, down from roughly $32.1 million on September 30, 2025.

Positive

• Substantial new capital at Accelsius: Accelsius Holdings LLC raised approximately $40 million through sales of Series B-1 units to Legrand and Johnson Controls, on top of roughly $25 million previously raised from Johnson Controls in October 2025.
• Implied valuation benchmark: The new Series B-1 investment was based on a stated Accelsius valuation of approximately $665 million, providing a market-based reference point for the subsidiary’s value.
• Balance sheet improvement: Outstanding convertible debentures with Yorkville declined to about $6 million as of January 12, 2026, down from approximately $32.1 million as of September 30, 2025, a reduction of roughly $26.1 million.
• Strategic partner alignment: Governance, preemptive, information, and registration rights granted to Legrand (and also made available to Johnson Controls) and the expectation of reseller, private label, joint development, supply, and contract manufacturing agreements align Accelsius with two large industrial partners.

Negative

• None.

Insights

Equity & capital structure analyst

Innventure’s Accelsius unit raises $40M at a stated ~$665M valuation while significantly reducing convertible debenture balances.

The disclosure highlights fresh growth capital into Accelsius Holdings LLC, a subsidiary of Innventure. Accelsius sold Series B-1 units to Legrand and Johnson Controls for approximately $40 million, following an earlier October 2025 Series B-1 sale to Johnson Controls of about $25 million. The latest transaction references a valuation of approximately $665 million for Accelsius and sets an initial issue and conversion price of $36.4877 per Series B-1 unit.

Governance terms give Legrand one board seat on an expanded eight‑member Accelsius board and approval rights over defined “Preferred Decisions,” including large indebtedness above $20,000,000, new senior or pari passu securities, and increases in authorized units. Legrand and Johnson Controls also receive customary preemptive, information, and registration rights, indicating meaningful influence at the subsidiary level. The filing also reports that Innventure’s convertible debentures with Yorkville have fallen to about $6 million outstanding as of January 12, 2026, from approximately $32.1 million on September 30, 2025, a reduction of roughly $26.1 million. Subsequent agreements expected between Accelsius and Legrand, such as reseller, private label, joint development, supply, and contract manufacturing arrangements, could further shape Accelsius’ commercial trajectory.

Closing of Accelsius Series B Funding with Legrand and Johnson Controls

On December 29, 2025 (the “Closing” or “Closing Date”), Accelsius Holdings LLC (“Accelsius”), a subsidiary of Innventure, Inc. (the “Company”), issued and sold to Legrand DPC, LLC, a Delaware limited liability company (“Legrand”), 822,195 units of Accelsius’ Series B-1 Units (the “Series B-1 Units”) for gross proceeds of approximately $30 million. Additionally, on the Closing Date, Accelsius issued and sold to Johnson Controls, Inc., a Wisconsin corporation and an existing holder of Series B-1 Units (“JCI”), an additional 274,065 units of the Series B-1 Units for gross proceeds of approximately $10 million. The approximately $40 million of aggregate gross proceeds to Accelsius from the Closing is in addition to the approximately $25 million of gross proceeds from the issuance and sale of Series B-1 Units to JCI on October 2, 2025, which was previously disclosed in the Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on October 6, 2025 (the “Prior Form 8-K”). For a summary of the rights provided to JCI in connection with its prior investment, see the Prior Form 8-K.

Accelsius will use the proceeds from the sale of the Series B-1 Units, after deducting certain offering expenses, for general company purposes. The Series B-1 Units are convertible at any time and from time to time into Accelsius’ Class A Common Units by dividing the Series B-1 Unit’s Issue Price (as defined below) by the Conversion Price (as defined below) in effect at the time of conversion. The “Issue Price” means $36.4877 per unit, subject to appropriate adjustment in the event of any unit dividend, unit split, combination or other similar recapitalization with respect to the applicable Series B-1 Units. The “Conversion Price” shall initially equal $36.4877 and will be subject to certain adjustments.

The Series B-1 Units have not been registered under the Securities Act of 1933, as amended, may not be offered or sold absent registration or an applicable exemption from registration requirements and are subject to certain restrictions on transfer.

Amendment of Accelsius’ Operating Agreement

In connection with the Closing, Accelsius amended its limited liability company agreement (“Operating Agreement”) to, among other things, include Legrand as a member and expand the size of Accelsius’ board of directors (the “Board”) to eight directors. The amendment to the Operating Agreement provides that, for so long as Legrand and its affiliates continue to beneficially own an aggregate of at least 50% of the Series B-1 Units purchased by Legrand (subject to appropriate adjustment for any unit splits, unit dividends, combinations, recapitalizations and the like or any conversion), Legrand will be entitled to designate and remove one director (the “Legrand Director”). The Legrand Director will be entitled to one vote on all matters that come before the Board and will be entitled to be a member of any committee of the Board or of the board of directors or managers of any subsidiary of Accelsius.

The approval of the Legrand Director is required with respect to any Preferred Decision (as defined in the Operating Agreement). Such “Preferred Decisions” include, among others, (i) any amendment of any provision of the Operating Agreement that would adversely affect the special rights, powers, or preferences of the Series B-1 Units, (ii) the incurrence or guarantee of indebtedness by Accelsius in excess of $20,000,000 in a single transaction or series of related transactions, (iii) the creation of any new class or series of units that would rank senior or pari passu to the Series B-1 Units, and (iv) an increase in the authorized number of Accelsius’ Class A Common Units, Class C Units, or any series of preferred units.

Additionally, the amendment to the Operating Agreement provides Legrand, subject to certain exceptions and conditions, with certain customary preemptive rights, rights of first refusal and rights of co-sale with respect to transfers by other members, information rights and registration rights. Such customary rights, as set forth in the Operating Agreement and which are also made available to JCI, are described in more detail in the Prior Form 8-K.

Agreements with Legrand

On or after Closing, Accelsius expects to enter into several agreements with Legrand, including a reseller agreement, private label agreement, joint development agreement, supply agreement, and contract manufacturer agreement.
