“We delivered solid results across our flagship products and growing momentum in our gaming business in the second quarter of 2026,” said Mr. Tao Yang, Founder, Chairman and CEO of Yalla. “Our revenues exceeded the upper end of our guidance, driven by an 11.6% year-over-year increase in revenues from games services. Meanwhile, our core products continued to build momentum, with refined operations and targeted marketing driving a sequential rebound in paying users for Yalla Ludo and a 12.3% year-over-year increase in overall average MAUs to 47.6 million.

“Beyond the sustained strength of our flagship products, we made progress in expanding our gaming ecosystem. Our new games, including our first self-developed match-3 title and desert-themed SLG title, continued to advance smoothly with a clear roadmap taking shape for the next stage of development. We also continued to strengthen our pipeline of self-developed products, spanning casual games, hyper-casual games, social products and AI applications, designed to maximize the synergy between our social and gaming ecosystems. Building on years of deep-rooted expertise in MENA, we will continue to unlock local opportunities and broaden our reach globally through strategic partnerships to deliver sustainable growth for our shareholders.”

Ms. Karen Hu, CFO of Yalla, commented, “In the second quarter of 2026, we continued to pursue high-quality development while maintaining solid profitability. Total revenues were US$82.6 million, with revenues from games services growing to US$34.2 million, increasing the segment’s contribution to 41.4%. While doubling our selling and marketing expenses year over year to support the promotion of new products, we maintained a healthy non-GAAP net margin of 41.7% through increased efficiency. Our balance sheet and cash flow remain ample to support our investments in business expansion as well as consistent shareholder returns. Going forward, we will continue to invest in long-term growth while driving value creation.”

Second Quarter 2026 Financial Results

Revenues

Revenues were US$82.6 million in the second quarter of 2026, compared with US$84.6 million in the second quarter of 2025, primarily due to a decrease in paying users attributable to the impact of recent geopolitical events in the broader region, partially offset by an increase in revenues from games services.

Non-GAAP Financial Measures

To supplement the financial measures prepared in accordance with generally accepted accounting principles in the United States, or GAAP, this press release presents non-GAAP financial measures, namely non-GAAP operating income, non-GAAP net income, non-GAAP net margin and non-GAAP basic and diluted earnings per ordinary share, as supplemental measures to review and assess the Company’s operating performance. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP. We define non-GAAP operating income as operating income excluding share-based compensation. We define non-GAAP net income as net income excluding share-based compensation. We define non-GAAP net margin as non-GAAP net income as a percentage of revenues. We define non-GAAP net income attributable to Yalla Group Limited’s shareholders as net income attributable to Yalla Group Limited’s shareholders, excluding share-based compensation. We define non-GAAP earnings per ordinary share as non-GAAP net income attributable to Yalla Group Limited’s shareholders, divided by the weighted average number of basic and diluted shares outstanding.

By excluding the impact of share-based compensation expenses, which are non-cash charges, the Company believes that the non-GAAP financial measures help identify underlying trends in its business and enhance the overall understanding of the Company’s past performance and future prospects. Investors can better understand the Company’s operating and financial performance, compare business trends among different reporting periods on a consistent basis and assess its core operating results, as they exclude share-based compensation expenses, which are not expected to result in cash payments. The Company also believes that the non-GAAP financial measures allow for greater visibility with respect to key metrics used by the Company’s management in its financial and operational decision-making.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using the non-GAAP financial measures is that they do not reflect all items of income and expense that affect the Company’s operations. Share-based compensation has been and

may continue to be incurred in the Company’s business and is not reflected in the presentation of non-GAAP financial measures. Further, the non-GAAP financial measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

The Company compensates for these limitations by providing the relevant disclosure of its non-GAAP financial measures in the reconciliations to the nearest U.S. GAAP performance measures, all of which should be considered when evaluating its performance. The Company encourages investors and others to review its financial information in its entirety and not rely on a single financial measure.

Reconciliations of GAAP and non-GAAP results are set forth at the end of this press release.
