FAQ

What does Novonix (NVX) report in this March 2026 Form 6-K?

Novonix reports multiple Appendix 3Y notices detailing changes in directors’ shareholdings after equity awards vested. The filing shows ordinary shares issued on vesting of share rights for several directors, updating their direct and indirect interests under Australian listing rule 3.19A.2.

How did director Anthony Bellas’s Novonix (NVX) shareholding change?

Anthony Bellas had 120,594 share rights vest into 120,594 ordinary shares held indirectly via Loch. After this change, he holds 2,398,145 ordinary shares indirectly through Loch, 230,246 ordinary shares indirectly through Super, and 95,744 ordinary shares directly, reflecting increased equity exposure.

What change was reported for Novonix (NVX) director Robert Natter?

Robert Natter reported the vesting of 120,594 share rights into 120,594 ordinary shares, moving from rights to actual shares. This is recorded as an indirect interest, converting a contingent equity position into issued ordinary shares without indicating any on-market buying or selling activity.

Did any Novonix (NVX) director trade during a closed period?

The Appendix 3Y notices state the relevant security interests were not traded during a closed period where prior written clearance was required. Each form confirms that no such closed-period trading occurred in connection with these changes arising from the vesting of share rights into ordinary shares.

How did Sharan Burrow’s Novonix (NVX) holdings change according to Appendix 3Y?

Sharan Burrow, a Novonix director, reported a change in direct interests due to the issue of shares on vesting of share rights. After this transaction, she holds 215,739 ordinary shares, reflecting increased direct ownership through equity compensation rather than open-market purchases or sales.

What is the nature of changes reported for Novonix (NVX) director Nicholas Liveris?

Nicholas Liveris reported an increase in direct ordinary share holdings attributed to the issue of shares on the vesting of share rights. Following this change, he holds 659,090 ordinary shares. The notices describe this as an equity award vesting event, not a market trade transaction.
