Neither Kaleyra nor GigCapital assumes any obligation to update the information in this communication. This communication does not constitute an offer to sell or a solicitation of an offer to buy, or the solicitation of any vote or approval in any jurisdiction in connection with a proposed potential business combination between Kaleyra and GigCapital or any related transactions, nor shall there be any sale, issuance or transfer of securities in any jurisdiction where, or to any person to whom, such offer, solicitation or sale may be unlawful. Any offering of securities or solicitation of votes regarding the proposed transaction will be made only by means of a proxy statement that complies with applicable rules and regulations promulgated under the Securities Act of 1933 and Securities Exchange Act of 1934. FORWARD LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of U.S. federal securities laws regarding the proposed transactions. Such forward-looking statements include, but are not limited to, statements regarding the expectations, hopes, beliefs, intentions, plans, prospects, financial results or strategies regarding the proposed transactions and the future held by the Kaleyra and GigCapital management teams. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements.

The words anticipate, believe, continue, could, estimate, expect, intends, may, might,” plan, possible, potential, predict, project, should, would and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. The forward- looking statements contained in this presentation are based on certain assumptions of GigCapital and/or Kaleyra management in light of their respective experience and their perception of historical trends, current conditions and expected future developments and their potential effects on us as well as other factors we believe are appropriate in the circumstances. There can be no assurance that future developments affecting Kaleyra or GigCapital will be those anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond the control of the parties) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of the assumptions being made prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. Certain market data information in this presentation is based on the estimates of Kaleyra and GigCapital management. Kaleyra and GigCapital obtained the industry, market and competitive position data used throughout this presentation from internal estimates and research as well as from industry publications and research, surveys and studies conducted by third parties. Kaleyra and GigCapital believes their estimates to be accurate as of the date of this presentation. However, this information may prove to be inaccurate because of the method by which Kaleyra or GigCapital obtained some of the data for its estimates or because this information cannot always be verified due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process. 2Legal Disclaimer INVESTOR PRESENTATION This communication is for informational purposes only and has been prepared to assist interested parties in making their own evaluation with respect to the proposed potential business combination between Kaleyra S.p.A.

Legal Disclaimer (Cont’d) NON-GAAP FINANCIAL MEASURE AND RELATED INFORMATION This presentation includes reference to adjusted EBITDA, a financial measure that is not prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Adjusted EBITDA is defined as of any date of calculation, the consolidated pro forma earnings of Kaleyra and its subsidiaries, before finance income and finance cost (including bank charges), tax, depreciation and amortization calculated from the audited consolidated financial statements of such party and its subsidiaries (prepared in accordance with Italian GAAP, except for the subsidiaries, that have been prepared under local GAAP), plus (i) transaction expenses of Kaleyra and GigCapital, (ii) without duplication of clause (i), severance or change of control payments, (iii) any expenses related to company restructuring, (iv) any compensation expenses relating to stock options, restricted stock units, restricted stock or similar equity interests as may be issued by the post-combination company or any of its subsidiaries to their employees and (v) any provision for the write down of assets. The pro forma earnings of Kaleyra, which is an Italian company, and its subsidiaries, which include subsidiaries outside of the U.S., may not be prepared in conformance with Article 11 of Regulation S-X of the SEC. We are not able to forecast net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income including as a result of preparation using GAAP rather than Italian and other local GAAP as we have done historically, and therefore have not provided a reconciliation for forward-looking adjusted EBITDA. Adjusted EBITDA is being used to determine whether conditions have been achieved that would result in the issuance of the earnout. GigCapital management also believes that this non-GAAP measure of Kaleyra’s financial results will provide useful information to management and investors regarding certain financial and business trends relating to Kaleyra’s anticipated financial condition and results of operations. Investors should not rely on any single financial measure to evaluate Kaleyra’s anticipated business. ADDITIONAL INFORMATION ABOUT THE TRANSACTION AND WHERE TO FIND IT In connection with the proposed business combination and related transactions, if a definitive agreement is reached, GigCapital will file preliminary and definitive proxy statements with the SEC and will mail a definitive proxy statement and other relevant documents to its stockholders. Investors and security holders of GigCapital are advised to read, when available, the preliminary proxy statement, and amendments thereto, and the definitive proxy statement in connection with GigCapital ’s solicitation of proxies for its stockholders’ meeting to be held to approve the proposed business combination because the proxy statements will contain important information about the proposed business combination and related transactions and the parties to such arrangements. The definitive proxy statement will be mailed to stockholders of GigCapital as of a record date to be established for voting on the proposed business combination and related transactions. Stockholders will also be able to obtain copies of the proxy statement, without charge, once available, at the SEC’s website at www.sec.gov. PARTICIPANTS IN THE SOLICITATION Kaleyra, GigCapital, and their respective directors, executive officers and other members of their management and employees, may, under SEC rules, be deemed to be participants in the solicitation of proxies of GigCapital stockholders in connection with the proposed business combination and related transactions. Information concerning the interests of Kaleyra’s and GigCapital’s participants in the solicitation, which may, in some cases, be different than those of Kaleyra’s and GigCapital’s equity holders generally, will be available in the proxy statement relating to the proposed business combination to be filed by GigCapital with the SEC. The past performance of the members of the Kaleyra management team, GigCapital management team, Kaleyra, GigCapital, or any of their affiliates is not a guarantee of success with respect to the proposed business combination and related transactions. You should not rely on the historical record of the performance of Kaleyra management, GigCapital management, or any of their affiliates’ performance as indicative of our future performance when evaluating the proposed business combination and related transactions TRADEMARKS AND INTELLECTUAL PROPERTY All trademarks, service marks, and trade names of Kaleyra or GigCapital or their respective subsidiaries or affiliates used herein are trademarks, service marks, or registered trademarks of Kaleyra or 3 GigCapital, respectively, as noted herein.
