Offerings for economic interests in some of today's most dynamic private companies: Strong Enthusiasm for StartEngine's Funds In addition to offering single-asset Series, StartEngine’s diversified Funds provides exposure to multiple venture-backed companies with a single check. StartEngine has launched five Funds to date, all of which sold out. For example, the chart below shows a breakdown of our A.I. Chip Fund, which provided exposure to six private companies developing cutting-edge GPU, LPU, and marketing technologies. 9/12/25, 9:16 AM StartEngine (Reg A+) | StartEngine https://www.startengine.com/offering/startengine6 4/22

Howard also founded and sold Acclaim Games, which was subsequently acquired by Disney. In 2014, Howard co-founded StartEngine with Ron Miller. 9/12/25, 9:16 AM StartEngine (Reg A+) | StartEngine https://www.startengine.com/offering/startengine6 7/22

Kevin O'Leary, "Mr. Wonderful," is an entrepreneur, investor, and Shark Tank star. He’s a strategic advisor for StartEngine. “To be honest with you, I had wanted to compete with Howard out of the gate… but after seeing what he had built with the StartEngine team, it made a lot of sense to join him instead.” Kevin O’Leary is a paid spokesperson for StartEngine.

We define Adjusted EBITDA as net income (loss) calculated in accordance with GAAP adjusted to exclude interest expense, interest income, income taxes, depreciation, and amortization, and stock based compensation. We present Adjusted EBITDA because it is a key measure used by our management team to evaluate our operating performance, generate future operating plans and make strategic decisions.

In addition, our non-GAAP financial measures may not be the same as or comparable to similar non-GAAP financial measures presented by other companies.

StartEngine Marketplace StartEngine Marketplace (“SE Marketplace”) is a website operated by StartEngine Primary, LLC (“SE Primary”), a broker-dealer that is registered with the SEC and a member of FINRA and the SIPC. StartEngine Secondary (“SE Secondary”) is our investor trading platform. SE Secondary is an SEC-registered Alternative Trading System (“ATS”) operated by SE Primary that matches orders for buyers and sellers of securities. It allows investors to trade shares purchased through Regulation A+, Regulation Crowdfunding, or Regulation D for companies who have engaged StartEngine Secure LLC as their transfer agent. The term “Rapid,” when used in relation to transactions on SE Marketplace, specifically refers to transactions that are facilitated on SE Secondary, This is because, unlike with trades on the StartEngine Bulletin Board (“SE BB”), trades on SE Secondary are executed the moment that they are matched. StartEngine Bulletin Board (“SE BB”) is a bulletin board platform on which users can indicate to each other their interest to buy or sell shares of private companies that previously executed Reg CF or Reg A offerings not necessarily through SE Primary. As a bulletin board platform, SE BB provides a venue for investors to access information about such private company offerings and connect with potential sellers. All investment opportunities on SE BB are based on indicated interest from sellers and will need to be confirmed. Even if parties express mutual interest to enter into a trade on SE BB, a trade will not immediately result because execution is subject to additional contingencies, including among others, effecting of the transfer of the shares from the potential seller to the potential buyer by the issuer and/or transfer agent. SE BB is distinct and separate from SE Secondary. SE Secondary facilitates the trading of securities by matching orders between buyers and sellers and facilitating executions of trades on the platform. By contrast, under SE BB, SE Primary assists with the facilitation of a potential resulting trade off platform including, by among other things, approaching the issuer and other necessary parties in relation to the potential transaction. The term “Extended”, when used in relation to transactions on SE Marketplace denotes that these transactions are conducted via SE BB, and that these transactions may involve longer processing times compared to SE Secondary for the above-stated reasons. Even if a security is qualified to be displayed on SE Marketplace, there is no guarantee an active trading market for the securities will ever develop, or if developed, be maintained. You should assume that you may not be able to liquidate your investment for some time or be able to pledge these shares as collateral. The availability of company information does not indicate that the company has endorsed, supports, or otherwise participates with StartEngine. It also does not constitute an endorsement, solicitation or recommendation by StartEngine. StartEngine does not (1) make any recommendations or otherwise advise on the merits or advisability of a particular investment or transaction, (2) assist in the determination of the fair value of any security or investment, or (3) provide legal, tax, or transactional advisory services. 9/12/25, 9:16 AM StartEngine (Reg A+) | StartEngine https://www.startengine.com/offering/startengine6 22/22

2. Use of Non-U.S. GAAP Financial Measure In this email we are using a non-GAAP financial measure “Adjusted EBITDA”, which is a measure adjusted for the impact of specified items and are not in accordance with GAAP. We define Adjusted EBITDA as net income (loss) calculated in accordance with GAAP adjusted to exclude interest expense, interest income, income taxes, depreciation, and amortization, and stock-based compensation. We present Adjusted EBITDA because it is a key measure used by our management team to evaluate our operating performance, generate future operating plans and make strategic decisions. We believe Adjusted EBITDA provides useful information to investors regarding our operational performance and our ability to generate cash flows. Non-GAAP information should be considered as supplemental in nature and is not meant to be considered in isolation or as a substitute for the related financial information prepared in accordance with GAAP. In addition, our non-GAAP financial measures may not be the same as or comparable to similar non-GAAP financial measures presented by other companies. The following table reconciles net income (loss), the most directly comparable U.S. GAAP measure, to Adjusted EBITDA for the periods presented. Please refer to our Form 10-Q/A for the three months ended June 30, 2025, for more information on our financial statements for this period found HERE. 3.
