Explanatory Note:

On April 21, 2026, the Company entered into a definitive share acquisition agreement (the “Agreement”) with certain shareholders of YATOP Group Limited (collectively, the “YATOP Shareholders”) to acquire 18% of the equity interests in YATOP Group Limited (“YATOP”), a leading cross-border advertising and branding service growth partner.

Pursuant to the Agreement, the Company agrees to acquire 18% of the equity interests in YATOP in consideration of USD 10.8 million, to be paid through a share exchange. The equity value of YATOP at an estimated USD 60.8 million based on professional third-party valuation.

YATOP is a premier TikTok Tier-1 agency and a leading TikTok ecosystem partner. Its core operating entities, which are located in Hong Kong, commenced business in 2024 and have demonstrated rapid scale-up and strong profitability.

For the fiscal year ended December 31, 2025, YATOP recorded unaudited revenue of USD 6.5 million with a net profit of USD 2 million. Driven by its expanding global footprint, YATOP’s revenue is projected to exceed USD 10 million in 2026.

As an official TikTok partner—holding TikTok Shop Partner (TSP), Creator Agency Partner (CAP), TikTok Affiliate Partner (TAP), TikTok Creative Exchange (TTCX), and TikTok Ads Manager (TTAM) certifications—YATOP provides end-to-end services including influencer marketing, short-form video production, live-streaming operations, paid media services, and e-commerce enablement through live-streaming collaborations. Unlike traditional agencies, YATOP focuses on empowering global brands—from Japan, China, the United States, and Mexico—to scale their presence on TikTok through localized content and data-driven strategies. Furthermore, YATOP has established deep partnerships with numerous global blue-chip brands, including Crocs, Nintendo, Midea, Anker and so on, helping them translate traffic into sales performance and achieve significant Gross Merchandise Value (“GMV”) growth.

The parties expect to complete the acquisition on or around May 2026.

On April 27, 2026, the Company issued a press release announcing the YATOP acquisition. A copy of the press release is furnished as Exhibit 99.1 to this Report on Form 6-K and is incorporated herein by reference.
