Insider purchases (SEC Form 4, open-market, last ~7 months) (ATO)

1 purchase, $50K. Private placements, offerings, dividend reinvestment and employee stock purchase plan buys are excluded.

Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

From Atmos Energy Corporation's Latest SEC 10-K Filing (filed 2025-11-14)

Key Strengths & Strategy (as disclosed to the SEC)

• Our customers' demand on our system is not necessarily indicative of our ability to meet current or anticipated market demands or immediate delivery requirements because of factors such as the physical limitations of gathering, storage and transmission systems, the duration and severity of cold weather, the availability of gas reserves from our suppliers, the ability to purchase additional supplies on a short-term basis, and actions by federal and state regulatory authorities.
• GRIP allows us to include in our rate base annually approved capital costs incurred in the prior calendar year provided that we file a complete rate case at least once every five years; the most recent of which was completed in December 2023.
• As an instrument to reduce regulatory lag, formula rate mechanisms allow us to refresh our rates on an annual basis without filing a formal rate case.

Partnerships

• We currently have specific infrastructure programs in all of our distribution divisions with tariffs in place to permit the investment associated with these programs to have their surcharge rate adjusted annually to recover approved capital costs incurred in a prior test-year period.

Legal & Regulatory Risks (Item 1A, quoted)

• We may experience increased federal, state, and local regulation of the safety of our operations.
