What SEC filings does ONE Gas, Inc. submit to the SEC?

ONE Gas, Inc. (OGS) submits several types of SEC filings including Form 4 (insider transactions), Form 144 (proposed insider sales), 8-K reports (material events such as earnings releases, acquisitions, leadership changes), and periodic reports — the 10-Q (quarterly) and 10-K (annual). All filings are publicly available through SEC EDGAR.

What does a Form 4 filing tell me about OGS?

A Form 4 for OGS discloses a transaction by a company insider — typically a director, officer, or 10%+ shareholder. It shows the source-reported date, number of shares, price, and updated ownership. These facts do not establish motive or predict future returns.

How do I interpret an 8-K filing from ONE Gas, Inc.?

An 8-K signals a material event requiring prompt disclosure. Common triggers include earnings pre-announcements, acquisitions, leadership appointments or departures, credit changes, or regulatory actions. Read the item codes inside the filing to understand exactly what was disclosed before drawing conclusions.

What is the difference between a 10-K and 10-Q for OGS?

The 10-K is ONE Gas, Inc.'s annual report with fully audited financial statements, comprehensive MD&A, and complete risk factor disclosures — filed 60–90 days after fiscal year-end. The 10-Q is a lighter quarterly report with unaudited financials filed for the first three quarters. Together they provide a continuous financial picture of the company.

Where can I see all OGS SEC filings directly on EDGAR?

You can view all historical ONE Gas, Inc. filings on the SEC EDGAR company page for OGS. Each filing card on this page links directly to the original SEC document.

How often does ONE Gas, Inc. file with the SEC?

ONE Gas, Inc. files one 10-K per year and up to three 10-Qs per year. Form 4 insider transactions must be reported within two business days of each trade, so the frequency depends on how often insiders are buying or selling OGS shares. 8-K filings occur whenever a material event happens — which can be several times per quarter for an active company.

OGS Filing Activity Snapshot 2026-05-26 — 2026-09-29

Insider Transactions (Form 4)

0 buys vs 0 sells

Insider buying and selling activity is balanced in this period.

Insider Transactions 9 · Forms 3, 4 and 5

A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 9 filings in this group are Form 4s for ONE Gas, Inc.

The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.

Across the 9 insider filings shown, the breakdown is 6 compensation award and 3 option exercise. None of the classified filings involved a discretionary open-market trade, so this period says nothing about what insiders think of the price.

What each transaction type means

Compensation award ×6: Shares were granted as compensation rather than purchased. No cash changed hands, so the filing reflects a pay decision by the company, not a judgement about the price.
Option exercise ×3: The insider converted options into shares. The exercise price was fixed when the options were granted, so the timing usually tracks an expiry schedule.

An 8-K reports a material event in the window between scheduled reports. There are 10 in this period for ONE Gas, Inc. Each 8-K names the item number it is filed under, and that number is the fastest way to tell a routine disclosure from a consequential one.
