REVENUE STREAM • Our group’s revenue is derived from event management services and stage production services. • Our diverse clientele includes public institutions, marketing and public relations ﬁrms, real estate corporations, and a number of established brands . This broad customer base reﬂects our ability to de - liver customized solutions that meet the high standards of various sectors . • For the ﬁscal year ending June 30 , 2024 , our revenue rose signiﬁcantly, primarily from event management services, which saw larger project sizes and higher average fees . We also experienced growth in stage production services revenue, driven by similar factors . • For the six months ending December 31 , 2024 , our revenue slightly decreased due to the local economic downturn, affecting client budgets and leading to event cancellations . Despite this, new clients and festival events helped offset some of the impact, while revenue from stage production services also declined for similar reasons .

COST OF REVENUE • Our cost of revenue primarily includes purchase costs for transportation, equipment, supplies, furniture, materials, and consumables, as well as labor and subcontracting costs for our event and exhibition projects . • For the ﬁscal year ending June 30 , 2024 , our cost of revenues increased signiﬁcantly due to larger projects in the entertainment and sports sectors, higher labor costs from expanding our workforce, and greater subcontracting expenses for additional resources . Overall, the cost increase was proportionately smaller than the rise in revenue, as ﬁxed costs did not scale with revenue growth . • For the six months ending December 31 , 2024 , our cost of revenues decreased mainly due to lower purchase costs from fewer large projects, reduced labor expenses from a smaller headcount, and a slight rise in subcontracting costs driven by inﬂation . Overall, the cost decrease outpaced the revenue decline, as last year's complex projects required higher expenditures .

• For the ﬁscal year ending June 30, 2024, our net income saw signiﬁcant growth primarily because we took on larger projects and charged higher average fees. • For the six months ending December 31, 2024, our net income declined primarily due to the non - capitalized audit expenses associated with the IPO project. • For the ﬁscal year ending June 30 , 2024 , our general administrative expenses increased mainly due to : i) higher staff costs from salary increases and additional hires, reﬂecting our growth, and ii) increased entertainment and travel expenses for marketing, which have successfully helped us attract new clients and secure event projects . • For the six months ended December 31 , 2024 , our general administrative expenses rose signiﬁcantly, primarily due to the non - capitalized audit expenses associated with the IPO project .
