**Item 8.01 Other Events.**

On March 19, the Company issued a press release announcing that the Board of Directors (the "Board") of Niagen Bioscience, Inc. (the "Company") approved an increase in the authorization under the Company's share repurchase program.

Under the amended authorization, the Company may repurchase up to $20.0 million of its outstanding common stock, representing an increase from the previously authorized $10.0 million share repurchase program approved by the Board on October 31, 2025. Through March 17, 2026, the Company has repurchased approximately $2.6 million of its common stock under the share repurchase program. Additional information regarding share repurchases will be reported in the Company's periodic reports filed with the SEC. While the Company had remaining capacity under its previously approved share repurchase program, the Board determined that it was in the best interests of the Company and its stockholders to increase the authorization to provide additional flexibility to return capital to stockholders and to repurchase shares at attractive prices, depending on market conditions.

The share repurchase program permits the Company to repurchase shares of its common stock from time to time in the open market, through privately negotiated transactions or otherwise, subject to market conditions, applicable securities laws and other factors. Repurchases may be conducted in accordance with Rule 10b-18 under the Securities Exchange Act of 1934 and may also be made pursuant to a Rule 10b5-1 trading plan, if adopted.

The repurchase program is expected to remain in effect for the previously approved 24 month period, unless earlier completed, suspended, modified or terminated at the discretion of the Company's Board of Directors.

The timing, number and value of shares repurchased under the program will depend on a variety of factors, including market conditions, the trading price of the Company's common stock, corporate and regulatory requirements, and other considerations. The share repurchase program does not obligate the Company to acquire any particular amount of shares, and the program may be suspended or discontinued at any time.

## Exhibit 99.1

**Exhibit 99.1**

**Niagen Bioscience Increases Share Repurchase Program to $20 Million**

LOS ANGELES – March 19, 2026 – <u>Niagen Bioscience, Inc</u>. (NASDAQ: NAGE), the global authority on NAD+ (nicotinamide adenine dinucleotide) with a focus on the science of healthy aging, today announced that its Board of Directors has authorized an increase to the Company's previously disclosed share repurchase program (the "Program"), raising the total authorization from $10 million to $20 million of the Company's outstanding common stock.

Through March 17, 2026, the Company has repurchased approximately $2.6 million of its common stock under the Share Repurchase Program. Additional information regarding share repurchases will be reported in the Company's periodic reports filed with the SEC.

Rob Fried, CEO, Niagen Bioscience, stated, "The recent repurchase of our common stock and $10 million increase in our program reflect the conviction we have in our strategy and long-term value. We will continue to take advantage of the disconnect between NAGE's market valuation and the underlying strength of our business opportunistically."

Repurchases under the Share Repurchase Program may be made from time to time in accordance with applicable securities laws and at such times, in such manner, and in such amounts as determined by the Company's management. These purchases may be executed through open market transactions, privately negotiated transactions, or pursuant to a trading plan that may be adopted in the future, in accordance with the Securities Exchange Act of 1934, as amended.

The Share Repurchase Program is authorized through October 31, 2027, unless earlier modified, suspended, or terminated at the discretion of the Company's Board of Directors. The program does not obligate the Company to repurchase any specific amount of its common stock.
