Fiscal year 2025 executive and director compensation, incentive-plan design, equity activity, and governance — every figure in this brief is traceable to its exact location in the company’s SEC filing — the document, the section, the page, and the table, linked directly.
Each company listed discloses SWX in its own benchmarking peer group, as disclosed in each company's most recent proxy statement within the last two proxy seasons. Two companies are therefore absent by design: one that named SWX in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Prior-year totals as disclosed in the corresponding proxy; deltas are computed values with the derivation shown in the register.
Every insider equity transaction reported on Form 4 after the 2025 proxy statement — acquisitions, dispositions, exercises, and withholdings — and therefore not reflected in any table in that document.

Transaction codes per Form 4: A acquisition · S open-market sale · F tax withholding · M option exercise · G gift. Value = shares × price as reported. Dividend-equivalent and fractional-share accrual rows (derivative Class A, under $10,000 and under 2,000 shares) are aggregated per date; every row appears in full below.

The nature of the Company's operations and competitive considerations have led the Compensation Committee to design and employ a compensation program that we believe is comparable to compensation programs widely used in the natural gas distribution industry. Performance is the critical component of our program, and both individual and overall Company performance can impact an NEO's level of compensation on an annual basis.

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.
Of the companies Southwest Gas Holdings names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.
Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including Southwest Gas Holdings.
Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

Read from each company's Compensation Discussion and Analysis: annual incentive payout as a percentage of target, the disclosed long-term vehicle mix, whether performance-share measures include a total shareholder return component, and the retained compensation consultant. “Not disclosed” appears only where the company's filing does not state the item.
Each figure's location is given both for the eye (section · page · table · row · column) and for a script (table/row/column index and exact character span in the filed document). Any figure can be independently confirmed against the source.
