Regulation FD regulatory
"Item 7.01 | Regulation FD Disclosure On Sept. 8, 2026, we announced"
Regulation FD is a rule that prevents company insiders, like executives, from sharing important information with some people before others get it. It matters because it helps ensure all investors have equal access to key news, making the stock market fairer and reducing chances of insider trading.
Emerging growth company regulatory
"Emerging growth company 2 [TABLE]"
An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.
Inline XBRL technical
"Cover Page Interactive Data File (embedded within the Inline XBRL document)"
Inline XBRL is a file format for financial filings that embeds machine-readable data tags directly inside the human-readable report, so the same document can be read by people and parsed by software. For investors it makes extracting, comparing and verifying financial numbers faster and more reliable—like a grocery list where each item also has a barcode—reducing manual errors and speeding up analysis.
S&P MidCap 400 Index market
"ONE Gas is included in the S&P MidCap 400 Index and is one"
An index that tracks the stock performance of 400 medium-sized publicly traded U.S. companies chosen for size and trading activity, serving as a snapshot of the mid-cap segment of the market. Think of it as a basket representing the health and returns of mid-sized firms; investors use it as a benchmark to compare funds, build diversified portfolios, and gauge how that slice of the economy is performing compared with small or large companies.
