International Financial Reporting Standards financial

"The consolidated financial statements are prepared in accordance with U.S. GAAP, which differ in certain respects from International Financial Reporting Standards"

International Financial Reporting Standards are a common set of accounting rules used by companies in many countries to prepare and present their financial statements. They matter to investors because they make results easier to compare across borders — like using the same measuring tape — so investors can assess profitability, cash flow and risk more reliably and spot differences that come from business performance rather than differing accounting methods.

U.S. GAAP financial

"The consolidated financial statements are prepared in accordance with U.S. GAAP, which differ in certain respects from International Financial Reporting Standards"

U.S. GAAP is a set of rules and standards that companies in the United States follow to prepare their financial reports. It helps ensure that financial information is consistent and clear, so investors and others can compare and understand a company's financial health easily.

convertible senior notes financial

"Under U.S. GAAP, the convertible senior notes were measured at amortized cost"

Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.

right-of-use assets financial

"Under U.S. GAAP, the amortization of the right-of-use assets and interest expense related to the lease liabilities are recorded together"

Right-of-use assets are the rights a company gains to use a physical space or equipment under a lease agreement. They are recorded as assets on the company's balance sheet, reflecting the value of future benefits from the leased item. For investors, these assets provide a clearer picture of a company's obligations and resources related to leasing arrangements, helping to assess its financial health and operational commitments.

redeemable non-controlling interest financial

"the Group determined that the NCI with redemption rights should be bundled and classified as redeemable NCI and mezzanine classified on the balance sheet"

financial liability financial

"IFRS requires the fair value of NCI redemption right ... to be recognized as a separate financial liability on the balance sheet"

Notes:

(i) Convertible senior notes

Under U.S. GAAP, the convertible senior notes were measured at amortized cost, with any difference between the initial carrying value and the repayment amount recognized as interest expenses using the effective interest method over the period from the issuance date to the maturity date. Under IFRS, the Group’s convertible senior notes were designated as at fair value through profit or loss such that the convertible senior notes were initially recognized at fair values. Subsequent to initial recognition, the Group considered that the amounts of changes in fair value of the convertible senior notes which were attributed to changes in own credit risk of the convertible senior notes recognized in other comprehensive income were insignificant. Therefore, the amounts of changes in fair value of the convertible senior notes were recognized in the profit or loss.

(ii) Leases

Under U.S. GAAP, the amortization of the right-of-use assets and interest expense related to the lease liabilities are recorded together as lease cost to produce a straight-line recognition effect in the income statement. Under IFRS, the amortization of the right-of-use asset is on a straight-line basis while the interest expense related to the lease liabilities are the amount that produces a constant periodic rate of interest on the remaining balance of the lease liability. The amortization of the right-of-use assets is recorded as lease expense and the interest expense is required to be presented in separate line items.

(iii) Investments measured at fair value

Under U.S. GAAP, convertible redeemable preferred shares and ordinary shares with preferential rights issued by privately-held companies without readily determinable fair values could elect an accounting policy choice. The Group elects the measurement alternative to record these equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Under IFRS, these investments were classified as financial assets at fair value through profit or loss and measured at fair value with changes in fair value recognized through profit or loss. Fair value changes of these long-term investments were recognized in the profit or loss.

(iv) Share-based compensation

Under U.S. GAAP, companies are permitted to make an accounting policy election regarding the attribution method for awards with service-only conditions and graded vesting features. The valuation method that the company uses (single award or multiple tranches of individual awards) is not required to align with the choice in attribution method used (straight-line or accelerated tranche by tranche). Under IFRS, companies are not permitted to choose how the valuation or attribution method is applied to awards with graded-vesting features. Companies should treat each installment of the award as a separate grant. This means that each installment would be separately measured and attributed to expense over the related vesting period, which would accelerate the expense recognition.

(v) Redeemable non-controlling interest

On October 31, 2020, the Group entered into a series of share purchase agreements with then existing shareholders of Shanghai Jiamian Information Technology Co., Ltd. or JM Tech, to acquire the majority of JM Tech’s equity interest. The Group agreed to redeem the non-controlling interests (“NCI”) held by founders and CEO of JM Tech under certain circumstances. Under US GAAP, the Group determined that the NCI with redemption rights should be bundled and classified as redeemable NCI and mezzanine classified on the balance sheet, since they are contingently redeemable upon the occurrence of certain conditional events, which are not solely within the control of the Group. The redeemable NCI is recognized at fair value on the acquisition date taking into account the probability of future redemption as well as estimated redemption amount, and such fair value includes the right of redemption, which is viewed as part of the accounting purchase price when applying acquisition accounting. Subsequently, the Group records accretion on the redeemable NCI as a whole to the redemption value over the period from the date of the acquisition to the date of earliest redemption. The accretion using the effective interest method, is recorded as deemed dividends to NCI holders. Under IFRS, as it is considered that the Group undertakes the obligation to purchase the remaining equity of JM Tech held by the founders and CEO at fair value, the risk and reward of the shares reside with non-controlling interests in the consolidated statements. Therefore, the Company recognized the NCI at fair value as permanent equity on acquisition date, and the fair value of such permanent equity NCI does not consider the redemption right. IFRS requires the fair value of NCI redemption right (present value of the estimated redemption amount) to be recognized as a separate financial liability on the balance sheet because the Group has an obligation to pay cash in the future to purchase the NCI shares. This separate financial liability is not viewed as part of accounting purchase price when applying acquisition accounting, which resulted in lower purchase price and therefore, a lower goodwill being recognized from the acquisition. The initial recognition of this financial liability is a reduction of the parent’s equity. Subsequent changes in the carrying amount of the financial liability are recognized as finance charges in the income statement.

FAQ

What does Weibo (WB) disclose in this Form 6-K?

Weibo provides a reconciliation between financial statements prepared under U.S. GAAP and IFRS. The filing details how accounting differences for convertible notes, leases, investments, share-based pay and redeemable non-controlling interests change reported income and balance sheet figures for 2023, 2024 and 2025.

How do Weibo (WB) 2025 profits differ under U.S. GAAP and IFRS?

For 2025, net income attributable to Weibo's shareholders was 449,020 thousand under U.S. GAAP and 536,151 thousand under IFRS. The difference mainly reflects fair value treatment of investments and convertible notes, lease accounting, share-based compensation and redeemable non-controlling interest liabilities under IFRS.

How do Weibo (WB) total assets change under IFRS versus U.S. GAAP?

As of December 31, 2025, Weibo reported total assets of 7,091,186 thousand under U.S. GAAP and 7,213,946 thousand under IFRS. The higher IFRS figure primarily comes from measuring certain long-term investments at fair value, which increases asset values compared with cost-based U.S. GAAP treatment.

How are Weibo (WB) convertible senior notes treated differently under IFRS?

Under U.S. GAAP, Weibo measures convertible senior notes at amortized cost with interest expense using the effective interest method. Under IFRS, the notes are designated at fair value through profit or loss, so changes in fair value—rather than only amortized cost—flow through earnings and affect reported income.

What is the impact of IFRS on Weibo (WB) redeemable non-controlling interests?

Under U.S. GAAP, certain JM Tech non-controlling interests with redemption rights are classified as redeemable mezzanine equity with accretion recorded as deemed dividends. Under IFRS, the redemption right is a separate financial liability, while the non-controlling interests remain permanent equity, changing goodwill, finance charges and equity presentation.

How does lease accounting differ for Weibo (WB) under IFRS versus U.S. GAAP?

U.S. GAAP records a combined straight-line lease cost, blending right-of-use asset amortization and interest on lease liabilities. IFRS separates these: amortization of right-of-use assets is recorded as lease expense, while interest on lease liabilities appears in interest expense, affecting operating costs and finance expense lines differently.
