REVIEW OF FIRST QUARTER 2026 FINANCIAL RESULTS

Revenues

Online game revenues for the first quarter of 2026 were KRW 25,906 million (US$ 17,004 thousand), representing a 9.8% increase QoQ from KRW 23,594 million and a 37.8% increase YoY from KRW 18,806 million. The increase QoQ was mainly attributable to increased revenue from Ragnarok Online in Japan. The increase YoY was largely due to increased revenue Ragnarok Online in Thailand and initial revenues from Ragnarok Online America Latina launched in Latin America on May 28, 2025.

Mobile game revenues were KRW 132,800 million (US$ 87,168 thousand) for the first quarter of 2026, representing a 54.1% increase QoQ from KRW 86,175 million and a 15.0% increase YoY from KRW 115,486 million. The increase QoQ attributed to initial revenues from Ragnarok: The New World launched in Taiwan, Hong Kong and Macau on January 15, 2026, increased revenues from Ragnarok X: Next Generation in Global and initial revenues from Ragnarok Origin Classic launched in Southeast Asia (except Vietnam), Taiwan, Hong Kong, Macau and Korea on March 26, 2026. Such increase was partially offset by decreased revenues from Ragnarok: Twilight in Southeast Asia and Ragnarok M: Classic in Taiwan, Hong Kong, Macau and Global. The increase YoY was largely due to initial revenue from Ragnarok: The New World launched in Taiwan, Hong Kong and Macau on January 15, 2026 and increased revenue from Ragnarok X: Next Generation in Global. Such increase was partially offset by decreased revenues from Ragnarok M: Classic in Southeast Asia, Ragnarok: Rebirth in Taiwan, Hong Kong and Macau and Ragnarok Origin in Southeast Asia.

Other revenues were KRW 3,172 million (US$ 2,082 thousand) for the first quarter of 2026, representing a 13.8% decrease QoQ from KRW 3,681 million and remaining flat YoY from KRW 3,172 million.

Cost of Revenue

Cost of revenue was KRW 110,224 million (US$ 72,349 thousand) for the first quarter of 2026, representing a 48.4% increase QoQ from KRW 74,262 million and a 26.0% increase YoY from KRW 87,458 million. The increase QoQ was mainly due to initial commission paid for mobile game service related to Ragnarok: The New World in Taiwan, Hong Kong and Macau. The increase YoY was primarily due to initial commission paid for mobile game service related to Ragnarok: The New World in Taiwan, Hong Kong and Macau and increased commissions paid for mobile game services related to Ragnarok X: Next Generation in Global and Ragnarok: Twilight in Southeast Asia.

Operating Expenses

Operating expenses were KRW 20,824 million (US$ 13,669 thousand) for the first quarter of 2026, representing a 24.2% decrease QoQ from KRW 27,468 million and a 17.6% decrease YoY from KRW 25,276 million. The decrease QoQ was mainly due to decreased advertising expenses for Ragnarok Online in Thailand, Nobunaga's Ambition: The Road to the World in Japan and Ragnarok Abyss in Southeast Asia, and impairment losses on other non-current assets. The decrease YoY was mainly due to decreased advertising expenses for Ragnarok Idle Adventure Plus in Global, Ragnarok Begins in Taiwan, Hong Kong and Macau and Ragnarok V: Returns in Thailand, Indonesia and Philippines, and research and development expenses.

Profit Before Income Tax Expense

Profit before income tax expense was KRW 38,325 million (US$ 25,155 thousand) for the first quarter of 2026 compared with profit before income tax expense of KRW 16,576 million for the fourth quarter of 2025 and profit before income tax expense of KRW 28,450 million for the first quarter of 2025.

Net Profit

As a result of the foregoing factors, Gravity recorded a net profit attributable to parent company of KRW 29,394 million (US$ 19,294 thousand) for the first quarter of 2026 compared with net profit attributable to parent company of KRW 12,312 million for the fourth quarter of 2025 and a net profit attributable to parent company of KRW 22,038 million for the first quarter of 2025.
