Key Terms

reverse stock split, cusip, par value, equity compensation plan

4 terms

reverse stock split financial

"to effect a 1-for-21 reverse stock split of its common stock."

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.

cusip financial

"under the existing ticker symbol “AMIX” but with a new CUSIP number 05330T304."

A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.

View in glossary

par value financial

"with no change in the nominal par value per share of $0.001."

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

equity compensation plan financial

"the number of shares reserved for issuance under the Company’s equity compensation plan"

A plan by which a company gives employees, directors or contractors ownership or the right to buy ownership in the company through stock, options or similar awards — think of promising slices of the company pie as part of someone's pay. It matters to investors because these awards can change the number of shares outstanding, affect reported profits and influence management’s decisions; large or generous plans can dilute existing holders and alter incentives over time.

THE WOODLANDS, TX, June 18, 2026 (GLOBE NEWSWIRE) -- Autonomix Medical, Inc. (NASDAQ: AMIX) (“Autonomix” or the “Company”), a medical device company dedicated to advancing precision nerve-targeted treatments, today announced that it filed an amendment to its amended and restated certificate of incorporation with the Secretary of State of the State of Delaware to effect a 1-for-21 reverse stock split of its common stock. The reverse stock split will take effect at 12:01 am (Eastern Time) on June 24, 2026, and the Company’s common stock will open for trading on The Nasdaq Capital Market on June 24, 2026 on a post-split basis, under the existing ticker symbol “AMIX” but with a new CUSIP number 05330T304.

As a result of the reverse stock split, every 21 shares of the Company’s common stock issued and outstanding prior to the opening of trading on June 24, 2026 will be consolidated into one issued and outstanding share, with no change in the nominal par value per share of $0.001. No fractional shares will be issued, if, as a result of the reverse stock split, a stockholder would become entitled to a fractional share because the number of shares of common stock they hold before the reverse stock split is not evenly divisible by the split ratio. Instead, the stockholder will be entitled to receive a cash payment in lieu of a fractional share.

As a result of the reverse stock split, the number of shares of common stock outstanding will be reduced from approximately 11.4 million shares to approximately 543,000 shares, and the number of authorized shares of common stock will remain at 500 million shares. In addition, the number of shares reserved for issuance under the Company’s equity compensation plan immediately prior to the reverse stock split will be reduced proportionately.
