GigCapital7 Corp.

As of the date of this Quarterly Report on Form 10-Q, we supplement the risk factors disclosed in our Annual Report on Form 10-K for the period from May 8, 2024 (date of inception) through December 31, 2024 filed with the SEC on March 6, 2025 with the following risk factor. Any of these factors disclosed in our Annual Report on Form 10-K or herein could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

Changes in international trade policies, tariffs and treaties may have a material adverse effect on our search for an initial business combination target, our ability to complete an initial business combination, and/or our business, financial condition and results of operations following completion of an initial business combination.

There have recently been significant changes to international trade policies and tariffs affecting imports and exports. Any significant increases in tariffs on goods or materials or other changes in trade policy could negatively affect our search for a target and/or our ability to complete our initial business combination. Recently, the U.S. has implemented a range of new tariffs and increases to existing tariffs. In response to the tariffs announced by the U.S., other countries have imposed, are considering imposing, and may in the future impose new or increased tariffs on certain exports from the U.S. There is currently significant uncertainty about the future relationship between the U.S. and other countries with respect to trade policies, taxes, government regulations and tariffs, and we cannot predict whether, and to what extent, current tariffs will continue or trade policies will change in the future.

Tariffs, or the threat of tariffs or increased tariffs, could have a significant negative impact on certain businesses (either due to domestic businesses’ reliance on imported goods or dependence on access to foreign markets, or foreign businesses’ reliance on sales into the U.S.). In addition, retaliatory tariffs could have a significant negative impact on foreign businesses that rely on imports from the U.S., and domestic businesses that rely on exporting goods internationally. These tariffs and threats of tariffs and other potential trade policy changes could negatively affect the attractiveness of certain initial business combination targets, or lead to material adverse effects on a post-business combination company. Among other things, historical financial performance of companies affected by trade policies and/or tariffs may not provide useful guidance as to the future performance of such companies, because future financial performance of those companies may be materially affected by new U.S. tariffs or foreign retaliatory tariffs, or other changes to trade policies. The business prospects of a particular target for a business combination could change even after we enter into a business combination agreement, as a result of tariffs or the threat of tariffs that may have a material impact on that target’s business, and it may be costly or impractical for us to terminate that business combination agreement. These factors could affect our selection of a business combination target.

We may not be able to adequately address the risks presented by these tariffs or other potential changes in trade policy. As a result, we may deem it costly, impractical or risky to complete an initial business combination with a particular target or with a target in a particular industry or from a particular country. Consequently, the pool of potential target companies may be reduced, which could impair our ability to identify a suitable target and to complete an initial business combination. If we complete an initial business combination with such a target, the post-business combination company’s operations and financial results could be adversely affected as a result of tariffs or changes to trade policies, which may cause the market value of the securities of the post-business combination company to decline.
