## Exhibit 99.1

![image_0a.jpg](image_0a.jpg)

**QT Imaging 3:1 Reverse Stock Split Market Effective on October 24, 2025**

**Novato, Calif.** – October 24, 2025 – QT Imaging Holdings, Inc. ("QT Imaging" or the "Company") (OTCQB: QTIH), a medical device company engaged in research, development, and commercialization of innovative body imaging systems, today announced that it has implemented a 3:1 reverse stock split of the Company's issued and outstanding common stock which became market effective on October 24, 2025. The market effectiveness has been referenced to by FINRA in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission (the "SEC") on October 23, 2025, which Form 8-K referred to market effectiveness on October 24, 2025.

In addition, the Company's public warrants are being adjusted such that each warrant shall be exercisable for 0.33333809 shares of the Company's common stock and the exercise price of the warrants is adjusted on a 2.9999572:1 basis to increase the exercise price from $2.30 per share to $6.90 per share.

Continental Stock Transfer and Trust Company ("CST"), the Company's transfer agent, is acting as the exchange agent for the reverse stock split. Stockholders with book-entry shares or who hold their shares through a bank, broker or other nominee will not need to take any action. Stockholders of record holding certificates representing pre-split shares of the Company's common stock, as applicable, will receive a letter of transmittal from CST with instructions on how to surrender certificates representing pre-split shares. Stockholders should not send in their pre-split certificates until they receive a letter of transmittal from CST. Unless a stockholder specifically requests a new paper certificate or holds restricted shares, stockholders of record who held pre-split certificates will receive their post-split shares book-entry and will be receiving a statement from CST regarding their common stock ownership post-reverse stock split.

Additional information about the reverse stock split can be found in the Company's definitive proxy statement (the "Proxy Statement") filed with the SEC on July 17, 2025, which is available free of charge at the SEC's website, www.sec.gov, and on the Company's website at <u>https://qtimaging.com</u>.
