Nomura Securities filed change reports with a local finance bureau on August 20, 2026, covering GDEP Advance (5885.T), Plus Alpha Consulting (4071.T) and SHIFT (3697.T). The GDEP Advance filing, involving a TSE Standard Market-listed provider of AI computing infrastructure and high-performance computing solutions, cited an increase in joint holders. Nomura reported that its stake in Plus Alpha Consulting, a TSE Prime Market-listed talent management and text-mining technology company, fell by 1.53 percentage points to 6.61%. Its filing for SHIFT, a software testing and quality-assurance company also listed on the TSE Prime Market, cited a reduction of at least 1 percentage point in Nomura Securities Co., Ltd.'s shareholding ratio. The Plus Alpha Consulting and SHIFT filings also cited the conclusion or modification of a significant contract of 1% or more. All three reports used August 14 as the reporting obligation date, suggesting a simultaneous review or adjustment of positions across technology-related stocks. Under Japan's large shareholding reporting system, holders of more than 5% must file a change report when their stake changes by at least 1 percentage point or when joint-holder arrangements change.
