CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 20-F (the "Annual Report") of Triton International Limited contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that involve substantial risks and uncertainties. In addition, we, or our executive officers on our behalf, may from time to time make forward-looking statements in reports and other documents we file with the Securities and Exchange Commission (the "SEC"), or in connection with oral statements made to the press, potential investors or others. All statements, other than statements of historical facts, including statements regarding our strategy, future operations, future financial position, future revenues, future costs, prospects, plans and objectives of management are forward-looking statements. The words "expect," "estimate," "anticipate," "predict," "believe," "think," "plan," "will," "should," "intend," "seek," "potential" and similar expressions and variations are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

All forward-looking statements address matters that involve risks and uncertainties, many of which are beyond Triton's control. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements. These factors include, without limitation, economic, business, competitive, market and regulatory conditions and the following:

•decreases in the demand for leased containers;

•decreases in market leasing rates for containers;

•difficulties in re-leasing containers after their initial fixed-term leases;

•our customers' decisions to buy rather than lease containers;

•increases in the cost of repairing and storing our off-hire containers;

•our dependence on a limited number of customers and suppliers;

•customer defaults;

•decreases in the selling prices of used containers;

•extensive competition in the container leasing industry;

•risks stemming from the international nature of our businesses, including global and regional economic conditions and geopolitical risks, including international conflicts;

•decreases in demand for international trade;

•risks resulting from the political and economic policies of the United States and other countries, particularly China, including but not limited to, the impact of trade wars, duties and tariffs;

•disruption to our operations from failures of, or attacks on, our information technology systems;

•disruption to our operations as a result of natural disasters or public health crises;

•compliance with laws and regulations globally;

•risks related to the ownership of Triton by Brookfield Infrastructure, including the potentially divergent interests of our sole common shareholder and the holders of our outstanding indebtedness and preference shares, and our reliance on certain corporate governance exemptions, and that as a foreign private issuer we are not subject to the same disclosure requirements as a U.S. domestic issuer;

•the availability and cost of capital;

•restrictions imposed by the terms of our debt agreements;

•our ability to successfully complete, integrate and benefit from acquisitions and dispositions;

•changes in tax laws in Bermuda, the United States and other countries; and

•other risks and uncertainties, including those listed under Item 3.D, "Risk Factors" in this Annual Report and in the other documents we file with the SEC from time to time.

The foregoing list of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included herein and elsewhere. Any forward-looking statements made in this Annual Report are qualified in their entirety by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, Triton or its businesses or operations. Except to the extent required by applicable law, we undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future developments or otherwise.
