[SCHEDULE 13D/A] Innovative Solutions & Support SEC Filing

Rhea-AI Filing Summary

Schedule 13D/A Amendment No. 10 – Innovative Solutions & Support (ISSC)

Christopher Harborne and his wholly owned entity Klear Kite LLC have filed their tenth and final Schedule 13D amendment, disclosing that they now beneficially own 0 shares of ISSC, equal to 0 % of the 17,604,155 shares outstanding (as of 1 May 2025). The group therefore no longer qualifies as a 5 %-plus beneficial owner and has exited its reporting obligations under Section 13(d). The effective exit date is 10 July 2025; all sales were executed in the open market, as detailed in Exhibit 99.9 (not included in the excerpt).

Key points for investors

• Complete divestiture: Former >5 % holder has sold its entire position.
• Voting power: Both sole and shared voting/dispositive power are now zero.
• Filing purpose: Marks the end of the shareholder group’s Schedule 13D obligations (exit filing).

No operational, earnings, or strategic data are provided; the filing strictly updates ownership information.

Positive

• None.

Negative

• A former >5 % shareholder has fully divested, a potential bearish signal regarding confidence in ISSC’s outlook.
• The sudden increase in free float could exert downward price pressure until the market absorbs the additional shares.

Insights

Securities Analyst

TL;DR: Large insider completely exited ISSC on 10 July 2025, removing takeover optionality and potentially pressuring the share price.

The departure of a former 5 %+ holder often signals diminished conviction and can act as an overhang while the market digests additional free float. Although the filing offers no insight into ISSC’s fundamentals, loss of an activist-style shareholder reduces the probability of governance-driven catalysts such as strategic alternatives or board pressure. Near-term sentiment could turn cautious until new buyers absorb the released shares.

Corporate Governance Expert

TL;DR: Exit filing ends monitoring obligations; governance influence from Harborne/Klear Kite now null.

With beneficial ownership at zero, Harborne relinquishes any leverage to influence corporate strategy or board composition. Governance dynamics revert to the remaining shareholder base, potentially lowering activist scrutiny. While neutral from a compliance standpoint, the absence of a vocal investor may reduce accountability pressures on management.
