RocketBoots (ASX:ROC) said that the late lodgement of its director David Willington's Appendix 3Y was due to "an administrative oversight as part of a restructure of holdings" which was not initially disclosed to the firm, according to a Thursday Australian bourse filing.

Willington discovered the "oversight" as part of his private entity's December 2025 quarterly review process in January, after which it was communicated to the firm.

RocketBoots then sought to clarify the relevant details and to lodge the appendix. While the firm considers this to be an isolated incident and not related to any deficiencies in its internal processes, it has reminded all directors of their obligations under the listing rules, per the filing.

Its shares jumped 10% in recent trading on Thursday.
