WK Frater reveals 17.01% stake in Raytech

Raytech Holding Limited has a significant shareholder disclosed in a Schedule 13G filing.

Rhea-AI Filing Summary

Raytech Holding Limited has a significant shareholder disclosed in a Schedule 13G filing. WK FRATER HOLDINGS LIMITED reports beneficial ownership of 999,014 Ordinary Shares of Raytech Holding Limited, each with a par value of US$0.0001 per share.

This position represents 17.01% of Raytech’s Ordinary Shares outstanding. The reporting person holds sole voting power and sole dispositive power over all 999,014 shares, with no shared voting or dispositive power.

The 17.01% ownership is calculated using a total of 5,874,743 Ordinary Shares outstanding, derived from 2,724,911 shares outstanding prior to an offering and 3,149,832 shares sold in a public offering that closed on June 29, 2026.

Filing Explained

WK Frater reports a 17.01% stake with sole voting and disposal power; the filing discloses ownership concentration, not a holder transaction.

A Schedule 13G is the report used by a passive holder to disclose ownership above 5%. The July 9 filing reports that WK Frater Holdings Limited beneficially owns 999,014 Raytech ordinary shares.

The filing states that this equals 17.01% of 5,874,743 shares outstanding. WK Frater has sole power to vote and dispose of all 999,014 shares, with no shared voting or dispositive power reported.

The structural consequence for existing common holders is a disclosed 17.01% ownership stake carrying sole voting and disposal rights. The filing also says its share-count denominator includes 3,149,832 shares sold in a public offering that closed on June 29, 2026; that completed offering reference is separate from the 13G's ownership-reporting function.

No prior WK Frater position is supplied here, so this filing does not establish whether its ownership percentage changed.
