Rockwell Medical Announces 1-for-10 Reverse Stock Split

Rockwell Medical, Inc. (the "Company") (NASDAQ:RMTI), a healthcare company that develops, manufactures, commercializes, and distributes a portfolio of hemodialysis products to dialysis providers worldwide, today announced that its Board of Directors (the "Board") has authorized a 1-for-10 reverse split of the Company's issued and outstanding common stock (the "Reverse Stock Split"). The Board received approval at the Company's Annual Meeting of Stockholders on June 12, 2026 to approve and adopt an amendment to the Company's Certificate of Incorporation to effect a reverse stock split of the Company's common stock.

The Reverse Stock Split will become effective at 12:01 a.m. EDT on July 1, 2026. The Company's common stock will continue to trade under the symbol "RMTI" on the Nasdaq Capital Market. The new CUSIP number following the Reverse Stock Split will be 774374409.

"The Reverse Stock Split is primarily intended to bring the Company into compliance with the minimum bid price requirement of $1.00 per share for continued listing on Nasdaq. Rockwell Medical's Board of Directors believes that maintaining the listing of the Company's common stock on Nasdaq is in the best interests of the Company and its stockholders. Continued listing on Nasdaq can provide, among other benefits, enhanced liquidity for our common stock, broader access to capital, increased visibility in the marketplace, and the ability to attract and retain institutional investors," said Robert S. Radie, Chairman of the Board at Rockwell Medical.

When the Reverse Stock Split becomes effective on July 1, 2026, every ten (10) shares of the Company's common stock issued and outstanding will be automatically reclassified into one (1) new share of common stock. The Reverse Stock Split will not modify any rights or preferences of the shares of the Company's common stock. Proportionate adjustments will be made to the exercise prices and the number of shares underlying the Company's outstanding equity awards, as applicable, warrants, and convertible preferred stock, as well as to the number of shares issued and issuable under the Company's equity incentive plans. The common stock issued pursuant to the Reverse Stock Split will remain paid and non-assessable. The Reverse Stock Split will not affect the number of authorized shares of common stock of the Company authorized under the Company's Certificate of Incorporation or the par value of the common stock.

No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive fractional shares as a result of the Reverse Stock Split will be entitled to a cash payment in lieu thereof at a price equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing trading price per share of the common stock (as adjusted for the Reverse Stock Split) on the Nasdaq Capital Market on June 30, 2026.

Equiniti Trust Company LLC has been appointed by the Company to act as its exchange agent for the Reverse Stock Split. Stockholders owning pre-split shares via a bank, broker or other nominee will have their positions automatically adjusted to reflect the Reverse Stock Split and will not be required to take further action in connection with the Reverse Stock Split, subject to brokers' particular processes. Similarly, registered stockholders holding pre-split shares of the Company's common stock electronically in book-entry form are also not required to take further action in connection with the Reverse Stock Split.

Additional information about the Reverse Stock Split can be found in the Company's definitive proxy statement filed with the Securities and Exchange Commission (the "SEC") on April 30, 2026, as supplemented by the supplemental proxy materials filed with the SEC on May 11, 2026, which are available on the SEC's website, www.sec.gov, and the Company's website at ir.rockwellmed.com.
