Weekly ETH and Capital Summary

* To enhance transparency into the Company’s yield performance, SharpLink introduced a new reporting metric called “ETH Concentration.” This metric is calculated by dividing the number of ETH SharpLink holds by each 1,000 assumed diluted shares issued and outstanding (“Assumed Diluted Shares Outstanding”). Assumed Diluted Shares Outstanding represents the sum of (i) SharpLink’s actual shares of common stock issued and outstanding as of the end of each reporting period, inclusive of disclosed ATM sales, plus (ii) the additional shares that would be issued upon the assumed exercise or settlement of all outstanding warrants, pre-funded warrants, stock option awards, and restricted stock units. Notably, Assumed Diluted Shares Outstanding is not calculated using the treasury stock method. It does not account for equity award vesting conditions, stock option exercise prices, or contractual restrictions limiting the convertibility of debt instruments. Additionally, it excludes any assumed share repurchases that would ordinarily be considered under the treasury stock method.

Actual results could differ materially from those described in these forward-looking statements due to certain factors, including without limitation, the Company’s ability to achieve profitable operations, fluctuations in the market price of ETH that will impact the Company’s accounting and financial reporting (see accounting rules discussed below), government regulation of cryptocurrencies and online betting, changes in securities laws or regulations, customer acceptance of new products and services, the demand for its products and its customers’ economic condition, the impact of competitive products and pricing, the lengthy sales cycle, proprietary rights of the Company, changes in applicable laws or regulations, and its competitors, general economic conditions and other risk factors detailed in the Company’s annual report and other filings with the SEC.
