Southwest Gas Charts Growth Path After Centuri Exit

Southwest Gas ((SWX)) has held its Q4 earnings call. Read on for the main highlights of the call.

Southwest Gas used its latest earnings call to underline a clear, upbeat pivot toward a pure regulated utility model, buoyed by strong 2025 results and a cleaner balance sheet. Management acknowledged higher costs and execution risks, but framed them as controllable against the backdrop of upgraded credit ratings, robust liquidity and a sizeable long‑term growth runway led by the Great Basin expansion.

Strategic Simplification and Balance Sheet Strengthening

The company has completed the sale of Centuri, realizing an estimated $260 million net gain and eliminating all holding company debt, a key strategic milestone in simplifying the business. With nearly $600 million of cash on hand and more than $1.3 billion in total liquidity, Southwest Gas also secured S&P upgrades to BBB+ with a stable outlook for both the holding company and operating utility.

Strong Underlying Utility Financial Performance

Core utility earnings trends were solid, with adjusted EPS from continuing operations rising about 19% year over year from $3.07 in 2024 to $3.65 in 2025. Adjusted net income climbed 8.7% to $283.9 million, supported by roughly $120 million of operating margin improvement, largely from rate relief of $95.2 million and $11.5 million tied to customer growth.

2026 Guidance and Long-Term Growth Outlook

Management introduced 2026 adjusted EPS guidance of $4.17 to $4.32, implying another strong step‑up from the 2025 base and signaling confidence in earnings visibility. Longer term, the company targets a 12% to 14% adjusted EPS CAGR through 2030, with particularly front‑loaded growth of about 15% to 17% around 2028 to 2029 as major projects, including Great Basin, come online.

Great Basin Expansion — Commercial Support

The Great Basin expansion emerged as a centerpiece of the growth story, having secured nearly 800 MMcf/d of capacity commitments through its open season. The project, estimated at about $1.7 billion in capital with FERC prefiling approval in hand, is expected to add $215 million to $245 million of incremental annual margin once placed into service in late 2028.

Material Capital Plan and Rate Base Growth

Southwest Gas outlined a hefty five‑year capital plan of roughly $6.3 billion, with about 73% earmarked for its utility operations and 27% for Great Basin, including $1.25 billion of capex in 2026 alone. This spending underpins an expected five‑year rate base CAGR of approximately 9.5% to 11.5%, with the core utility running at about 7% annually even before layering in Great Basin growth.

Disciplined Financing and Credit Metrics

Financing for the growth agenda is designed to be balanced, with Great Basin targeted at a 50/50 debt‑to‑equity mix and about $325 million of net utility bond issuance anticipated in 2026. Importantly for bondholders and equity investors, no equity issuance is planned under the current ATM next year, and S&P‑adjusted FFO to debt is projected at roughly 19.7% for the holding company and 18.6% for the utility, well above downgrade triggers.

Shareholder Returns

Reflecting growing confidence in recurring cash flows, the board approved a 4% annual dividend increase to an annualized rate of $2.58 per share beginning in the second quarter of 2026. Management stressed an intention to maintain disciplined, sustainable dividend growth in line with strengthening earnings and cash generation rather than stretching the balance sheet.

Regulatory Progress in Arizona and Nevada

On the regulatory front, Southwest Gas filed a major Arizona rate case seeking more than $100 million in additional revenue, a roughly $3.9 billion rate base and a 10.25% allowed ROE with a modest fair‑value uplift, with residential bills estimated to rise about $5 per month. In Nevada, new legislation (SB417) paves the way for alternative ratemaking, with rulemaking underway and potential implementation of new mechanisms as soon as 2028, supporting earnings stability.

Executive Succession

Leadership continuity was another theme as long‑time CEO Karen Haller prepares to retire after nearly three decades with the company, handing the reins to Justin Brown effective May 8. Management framed the transition as a planned evolution that will support the company’s sharpened focus on regulated natural gas infrastructure and its ambitious multi‑year capital program.

Higher Operating and Non-Fuel Costs

While topline and margins improved, operating expenses moved higher, with O&M rising $16.8 million year over year. Excluding above‑target incentive compensation, O&M increased about 1.9%, driven chiefly by higher labor, cloud computing and outside services, partly offset by lower costs for leak surveys and line locating.

Increased Depreciation and Amortization

Depreciation and amortization also weighed on results, increasing by $27.6 million as the average gas plant in service grew around 7%, reflecting the ongoing build‑out of the system. An additional roughly $8 million of amortization related to regulatory account balances also contributed to the rise, though some of this impact is offset within operating margin through regulatory mechanisms.

Higher Interest Expense and PGA Carrying Charges

Net interest deductions climbed by $19.4 million, predominantly due to interest on overcollected purchased gas adjustment balances and a higher variable interest expense adjustment mechanism in Nevada. At the same time, other interest income fell by about $12.6 million as carrying charges on deferred PGA balances declined, putting incremental pressure on net earnings.

Near-Term Earnings Moderation from Project Build

Investors were cautioned that earnings will moderate somewhat during the build‑out phase of the Great Basin project, as capital under construction earns AFUDC but not full tariff returns until in service. Capital deployment is set to ramp into late 2027 and early 2028, and actual timing will hinge on the pace of permitting and regulatory approvals.

Execution and Regulatory Risks

Management emphasized that key projects and rate outcomes remain subject to regulatory and execution risk, including approvals under federal permitting processes, supply chain conditions and stakeholder engagement. These factors could alter project schedules or earnings realization, but the company expressed confidence in navigating these hurdles, pointing to its track record and constructive jurisdictions.

Legal/Regulatory Uncertainty in Arizona

In Arizona, a challenge by RUCO to a policy statement remains in the appellate process after a Superior Court decision allowed further review, injecting some legal uncertainty into the regulatory backdrop. Southwest Gas nonetheless characterized this issue as manageable and not a fundamental threat to its broader Arizona investment thesis or rate case trajectory.

HoldCo Cash Usage and 2026 Year-End Cash Position

The company plans to deploy its roughly $600 million of holding company cash at the start of 2026 to cover shareholder dividends and provide equity funding for that year’s capex program, especially at the utility. As a result, Southwest Gas expects to end 2026 with a minimal HoldCo cash balance, temporarily tightening its liquidity cushion but aligning capital with growth while avoiding new equity.

Guidance and Forward-Looking Commentary

Looking ahead, management’s guidance calls for 2026 adjusted EPS of $4.17 to $4.32 supported by a $1.25 billion capital plan, of which about $925 million targets the distribution business, within a broader $6.3 billion five‑year capex program. The strategy assumes no 2026 equity issuance, preserves BBB+ credit quality with FFO to debt comfortably above 17% over time and leans heavily on the 2028 Great Basin expansion to deliver sizable incremental margin and sustain double‑digit EPS growth.

Southwest Gas’s call painted a picture of a leaner, more focused regulated utility with a sizable project pipeline, stronger balance sheet and a clearly articulated growth algorithm. While cost inflation, regulatory timing and construction execution remain watch points, the combination of upgraded credit, robust rate base expansion and disciplined capital allocation left investors with a broadly constructive narrative on both earnings and dividend prospects.
