How is a reverse stock split disclosed, and what does Item 5.03 of Form 8-K cover?

Information as of 16 October 2026. Everything below comes from the SEC's Form 8-K and the investor glossary at Investor.gov, linked below. If anything here is wrong, tell us at contact@oqro.io and we will correct it.

What is a reverse split?

Investor.gov's glossary describes a reverse stock split as a reduction in the number of a company's outstanding shares with a corresponding increase in the price per share: a shareholder who held 1,000 shares at 1 dollar holds 100 shares at 10 dollars after a one-for-ten split, with the same total value. The glossary notes that companies often use a reverse split to raise a share price that has fallen below an exchange's minimum, since listing standards require a minimum bid price. Fractional shares that result are usually paid out in cash, so very small holders can be cashed out entirely. The total market value of the company does not change on the day of the split; only the share count and the price per share do. A forward split works the other way, multiplying the share count and dividing the price, and is reported under the same item when it changes the charter, or under Item 8.01 when the board can declare it as a stock dividend without a charter amendment. The ratio is chosen by the board within the range the shareholders approved, and the Form 8-K states the ratio the board settled on.

What does Item 5.03 of Form 8-K cover?

Form 8-K, the current report, lists in Item 5.03 the amendments to a company's articles of incorporation or bylaws and changes in its fiscal year. If a company amends its articles or bylaws, and a proposal for the amendment was not disclosed in a proxy or information statement, it has to disclose the effective date of the amendment and a description of the provision adopted or changed and, if applicable, the previous provision. A reverse split by charter amendment, which changes the authorized or outstanding share figures in the certificate, is reported here with the ratio and the effective date. 17 CFR 249.308 is the rule that designates Form 8-K for these reports, and the general instructions set the deadline: four business days after the event, unless the item says otherwise.

A reverse split needs shareholder approval in most states, so an Item 5.07 report of the vote, described in our article on Items 2.02, 5.07, 7.01 and 8.01, often precedes the Item 5.03 report, and the company usually adds an Item 8.01 or a press release under Item 7.01 announcing the new CUSIP number and the date the shares begin trading on a split-adjusted basis.

What changes on a company's filings after a split?

Every per-share figure is restated: historical prices in the company's reports are adjusted, options and convertible securities are adjusted by their own terms, and the share counts in later Forms 4 reflect the new number of shares. Options and warrants are adjusted by their own anti-dilution terms, so an option over 10,000 shares at 1 dollar becomes an option over 1,000 shares at 10 dollars. An insider's holding of 100,000 shares before a one-for-ten split is 10,000 shares after it; OQRO's price history is adjusted so the chart does not show a tenfold jump, while the filing itself always states the number of shares as of its own date.

What this does not tell you

A reverse split changes the unit of account, not the business. The Form 8-K does not say why the price fell, whether the exchange has granted or will grant continued listing, or what the company will do next. A reverse split is sometimes paired with an increase in authorized shares, which the same Item 5.03 report would describe; the two are separate decisions. OQRO describes the filing and its dates; it does not interpret the event or predict anything about a price. Nothing here is investment advice.
