Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

On October 31, 2024, Trinity held a conference call and webcast with respect to its financial results for the three month period ended September 30, 2024. The conference call scripts of Leigh Anne Mann, Vice President of Investor Relations; E. Jean Savage, Chief Executive Officer and President; and Eric R.

The conference call, News Release, and Presentation Materials, described below, included references to Adjusted Operating Results and Adjusted Earnings Per Share, Adjusted Return on Equity, Cash Flow from Operations with Net Gains on Lease Portfolio Sales, EBITDA and Adjusted EBITDA, which are not calculations based on generally accepted accounting principles (“GAAP”). Reconciliations of each of these non-GAAP measures to the most directly comparable GAAP measures have been included in the News Release and/or the Presentation Materials.

These factors include, but are not limited to: the product mix of expected railcar deliveries; the timing and amount of significant transactions and investments, such as lease portfolio sales, capital expenditures, and returns of capital to shareholders; and the amount and timing of certain other items outside the normal course of our core business operations. This information and the materials described in Item 7.01 are not "filed" pursuant to the Securities Exchange Act of 1934 and are not incorporated by reference into any Securities Act of 1933 registration statements.

("Trinity") hereby furnishes the information set forth in its News Release, dated May 2, 2023, announcing operating results for the three month period ended March 31, 2023, a copy of which is furnished as Exhibit 99.1 and incorporated herein by reference. On May 2, 2023, Trinity held a conference call and webcast with respect to its financial results for the three month period ended March 31, 2023. The conference call scripts of Leigh Anne Mann, Vice President of Investor Relations; E. Jean Savage, Chief Executive Officer and President; and Eric R. Marchetto, Executive Vice President and Chief Financial Officer; are furnished as Exhibit 99.2, and incorporated herein by reference. The conference call, News Release, and Supplemental Materials, described below, included references to Adjusted Operating Results and Adjusted Earnings Per Share, Pre-Tax Return on Equity, Adjusted Free Cash Flow, EBITDA and Adjusted EBITDA, which are not calculations based on generally accepted accounting principles (“GAAP”). Reconciliations of each of these non-GAAP measures to the most directly comparable GAAP measures have been included in the News Release and/or the Supplemental Materials. When forward-looking non-GAAP measures are provided, Trinity does not provide quantitative reconciliations of forward-looking non-GAAP measures to the most directly comparable GAAP measures because it cannot, without unreasonable effort, predict the timing and amounts of certain items included in the computations of each of these measures. These factors include, but are not limited to: the product mix of expected railcar deliveries; the timing and amount of significant transactions and investments, such as lease portfolio sales, capital expenditures, and returns of capital to shareholders; and the amount and timing of certain other items outside the normal course of our core business operations. This information and the materials described in Item 7.01 are not "filed" pursuant to the Securities Exchange Act of 1934 and are not incorporated by reference into any Securities Act of 1933 registration statements. Additionally, the submission of the report on Form 8-K is not an admission of the materiality of any information in this report that is required to be disclosed solely by Regulation FD. Item 7.01 Regulation FD Disclosure. See "Item 2.02 — Results of Operations and Financial Condition." Additionally, Trinity posted Supplemental Materials to its website to accompany the conference call; a copy of these materials is furnished as Exhibit 99.3 and incorporated herein by reference.
