REVIEW OF THIRD QUARTER 2025 FINANCIAL RESULTS

Revenues

Online game revenues for the third quarter of 2025 were KRW 25,968 million (US$ 18,487 thousand), representing an 18.2% increase QoQ from KRW 21,971 million and a 32.1% increase YoY from KRW 19,657 million. The increase QoQ was mainly attributable to initial revenue from Ragnarok Zero launched in Taiwan, Hong Kong and Macau on July 3, 2025.

The increase YoY was mainly due to initial revenues from Ragnarok Online America Latina launched in Latin America on May 28, 2025 and Ragnarok Zero launched in Taiwan, Hong Kong and Macau on July 3, 2025.

Mobile game revenues were KRW 109,571 million (US$ 78,007 thousand) for the third quarter of 2025, representing a 23.9% decrease QoQ from KRW 144,003 million and a 6.9% increase YoY from KRW 102,524 million. The decrease QoQ was mainly attributable to decreased revenues from Ragnarok M: Classic launched in Southeast Asia and Taiwan, Hong Kong and Macau. Such decrease was partially offset by initial revenue from Ragnarok: Twilight launched in Taiwan, Hong Kong and Macau on July 3, 2025, increased revenue from Ragnarok X: Next Generation launched in North, Central and South America, Oceania, England, Portugal, Spain and Ireland and initial revenues from Ragnarok M: Classic Global launched in North and South America, Europe, Middle East, certain regions of North Africa and Oceania on September 3, 2025. The increase YoY was mainly due to initial revenues from Ragnarok M: Classic launched in Taiwan, Hong Kong and Macau on April 16, 2025 and Southeast Asia on February 14, 2025, Ragnarok: Twilight launched in Taiwan, Hong Kong and Macau on July 3, 2025 and Ragnarok X: Next Generation launched in North, Central and South America, Oceania, England, Portugal, Spain and Ireland on May 8, 2025. This increase was partially offset by decreased revenues from Ragnarok Origin in North, Central and South America, Southeast Asia and Taiwan, Hong Kong and Macau and THE RAGNAROK in Taiwan, Hong Kong and Macau.

Other revenues were KRW 3,355 million (US$ 2,389 thousand) for the third quarter of 2025, representing a 29.6% decrease QoQ from KRW 4,766 million and a 45.8% decrease YoY from KRW 6,195 million.

Cost of Revenue

Cost of revenue was KRW 88,542 million (US$ 63,036 thousand) for the third quarter of 2025, representing a 22.3% decrease QoQ from KRW 114,006 million and a 16.1% increase YoY from KRW 76,261 million. The decrease QoQ was mainly due to decreased commission paid for mobile game services related to Ragnarok M: Classic launched in Southeast Asia and Taiwan, Hong Kong and Macau. The increase YoY was primarily due to increased commission paid for mobile game services related to Ragnarok M: Classic in Taiwan, Hong Kong and Macau and Southeast Asia, Ragnarok: Twilight in Taiwan, Hong Kong and Macau and Ragnarok X: Next Generation in North, Central and South America, Oceania, England, Portugal, Spain and Ireland.

Operating Expenses

Operating expenses were KRW 29,076 million (US$ 20,700 thousand) for the third quarter of 2025, representing a 21.6% decrease QoQ from KRW 37,064 million and an 18.5% increase YoY from KRW 24,539 million. The decrease QoQ was mainly due to decreased advertising expenses for Ragnarok Online America Latina in Latin America, Ragnarok: Back to Glory in Korea and Nobunaga's Ambition: The Road to the World in Japan and research and development expenses. The increase YoY was mainly due to increased advertising expenses for Ragnarok Idle Adventure Plus in Korea and Global and Nobunaga's Ambition: The Road to the World in Japan, salaries and commission paid.

Profit Before Income Tax Expense

Profit before income tax expense was KRW 27,207 million (US$ 19,369 thousand) for the third quarter of 2025 compared with profit before income tax expense of KRW 18,706 million for the second quarter of 2025 and profit before income tax expense of KRW 28,415 million for the third quarter of 2024.
