Analysis

On Dec 30, the day this news came out, the stock closed 21.2% below the previous close. A negative reaction despite the structural move would fit concerns that a reverse stock split alone does not change fundamentals. CODX traded close to its 52-week low and below the 200-day MA before the announcement, reflecting existing pressure. Past news flow showed mixed follow-through, so traders may have treated the split as mechanical rather than as a catalyst for operational improvement.

8 terms

reverse stock split financial

"to effect a reverse stock split of its common stock at a ratio of 1-for-30"

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.

Certificate of Incorporation regulatory

"filed a Certificate of Amendment to its Certificate of Incorporation"

A certificate of incorporation is an official government document that creates a corporation and records key facts such as its legal name, basic governance structure, and stock authorization—think of it as a company's birth certificate plus its basic rulebook. Investors care because it establishes the company’s legal existence, limits owners’ personal liability, and sets the framework for issuing shares and enforcing shareholder rights, which affects ownership, control and the company’s ability to raise capital.

Nasdaq Capital Market regulatory

"will continue to trade on The Nasdaq Capital Market under the symbol "CODX""

The Nasdaq Capital Market is a platform where smaller, emerging companies can list their shares for trading by investors. It provides these companies with access to funding and visibility, helping them grow, much like a local marketplace where new vendors can introduce their products to potential customers. For investors, it offers opportunities to discover early-stage companies with growth potential.

CUSIP financial

"The new CUSIP number for Co-Dx's common stock following the reverse stock split"

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

"without effecting a change to the par value per share"

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 incentive plans financial

"shares of common stock available for issuance under the Company's equity incentive plans"

Equity incentive plans are company programs that pay employees, executives, or directors with company stock, stock options, or share units instead of or in addition to cash, aiming to align their interests with shareholders—like giving team members a stake in the house they help build. For investors this matters because such plans can motivate better company performance but also dilute existing ownership and increase reported compensation costs, so they affect future earnings, voting power, and share value.

stock options financial

"reduction in the number of shares of common stock issuable upon the exercise of stock options"

Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.

warrants financial

"reduction in the number of shares of common stock issuable upon the exercise of stock options and warrants"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

SALT LAKE CITY, Dec. 30, 2025 /PRNewswire/ -- Co-Diagnostics, Inc. (Nasdaq: CODX) ("Co-Dx" or "the Company"), a molecular diagnostics company with a unique, patented platform for the development of molecular diagnostic tests, today announced that it has filed a Certificate of Amendment to its Certificate of Incorporation (the "Amendment") to effect a reverse stock split of its common stock at a ratio of 1-for-30 shares. The reverse stock split will become effective at 12:01 a.m. ET on Friday, January 2, 2026. Co-Dx's common stock will continue to trade on The Nasdaq Capital Market under the symbol "CODX" and will begin trading on a split-adjusted basis when the market opens on Friday, January 2, 2026. The reverse stock split is intended to enable the Company to regain compliance with the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market. The new CUSIP number for Co-Dx's common stock following the reverse stock split will be 189763 204.

At the Special Meeting of Stockholders held on December 5, 2025, the Company's stockholders approved a reverse stock split of Co-Dx common stock at a ratio of not less than 1-for-2 and not more than 1-for-30 shares, with such ratio to be determined by the Board of Directors. Additional information regarding the reverse stock split approved by stockholders can be found in the Company's definitive proxy statement filed with the Securities and Exchange Commission on November 10, 2025.

The Amendment provides that at the effective time of the reverse stock split, each 30 shares of the Company's issued and outstanding common stock will be automatically combined into one validly issued, fully paid and non-assessable share of common stock, without effecting a change to the par value per share. The reverse stock split will impact all shares of the Company's common stock outstanding immediately prior to the effective time of the reverse stock split, as well as the number of shares of common stock available for issuance under the Company's equity incentive plans. In addition, the reverse stock split will effect a reduction in the number of shares of common stock issuable upon the exercise of stock options and warrants outstanding immediately prior to the effectiveness of the reverse stock split with a corresponding increase in exercise price per share.

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 have those shares rounded up to the next whole share. Stockholders with shares in brokerage accounts should direct any questions concerning the reverse stock split to their broker; all other stockholders may direct questions to the Company's transfer agent, VStock Transfer, LLC.
