Business Overview: RGC Resources, Inc. (NASDAQ: RGCO)

---

Executive Summary

RGC Resources, Inc. is a holding company whose core subsidiary, Roanoke Gas Company, has distributed and sold natural gas to residential, commercial, and industrial customers in Roanoke, Virginia and surrounding localities since 1883 — making it one of the oldest continuously operating gas utilities in the United States. The regulated gas distribution business generates more than 99% of consolidated revenues, serving roughly 62,500 customers under exclusive municipal franchises in the cities of Roanoke and Salem and the Town of Vinton, all running through December 31, 2035.

Beyond its core utility, RGC Resources holds a minority investment through RGC Midstream, LLC, formed in 2015 to invest in the Mountain Valley Pipeline (MVP), along with sub-1% interests in the related Southgate and Boost pipeline expansion projects. For fiscal year 2025 (ended September 30, 2025), the company reported total operating revenues of $95.3 million, up about 13% from $84.6 million in fiscal 2024, with diluted EPS of $1.29, up from $1.16. The company operates with a lean workforce of 106 full-time employees.

1. Core Business Model & How They Work

RGC Resources operates the classic regulated natural-gas-utility model, supplemented by a pipeline equity investment:

[ Purchase natural gas on wholesale market ] ➡️ [ Transport via owned local distribution pipeline network ] ➡️ [ Deliver to ~62,500 residential/commercial/industrial customers in Roanoke, VA area ] ➡️ [ Virginia SCC approves rates & cost-recovery mechanisms ] ➡️ [ Stable regulated margin ]
                                                                                                                                         +
[ RGC Midstream: minority equity stake in Mountain Valley Pipeline & related projects ] ➡️ [ Equity earnings/distributions supplement utility income ]

Key mechanics:

1. Regulated monopoly franchise: Roanoke Gas holds the only natural gas distribution franchises and/or Certificates of Public Convenience and Necessity (CPCNs) in its Virginia service areas, insulating it from direct same-fuel competition within its territory.
2. Rate mechanisms smooth earnings: The company benefits from several Virginia State Corporation Commission (SCC)-approved cost-recovery and margin-stabilization mechanisms, including a Purchased Gas Adjustment (PGA), the SAVE infrastructure-replacement rider, a Weather Normalization Adjustment (WNA) that reduces weather-driven earnings volatility, an inventory carrying cost (ICC) rider, and an RNG (renewable natural gas) rider.
3. Multi-layered regulatory oversight: Rates and affiliate agreements are set by the Virginia SCC; pipeline safety is overseen federally by the PHMSA; and FERC regulates certain transportation and storage pricing — a dense but predictable regulatory framework typical of U.S. gas utilities.
4. Midstream pipeline optionality: The Mountain Valley Pipeline investment (plus related Southgate and Boost projects) gives RGC Resources exposure to interstate gas transportation infrastructure economics beyond its core local distribution franchise, diversifying earnings sources modestly.

3. Competitive Landscape

Roanoke Gas operates as a regulated monopoly within its franchise area, but faces competition at the fuel-choice level:

• No direct same-fuel competitors exist within Roanoke Gas's exclusive franchise territory, since it holds the only natural gas distribution rights there.
• Alternative energy sources — fuel oil, electricity, propane, and coal — compete for customer energy spend, particularly among industrial customers with the flexibility to switch fuel sources based on relative price.
• Solar and wind are specifically flagged in the company's own filings as a growing competitive threat over time, reflecting the broader U.S. utility sector's exposure to electrification and renewable-energy substitution trends.
• As a small, single-state gas utility, RGC Resources does not compete directly with larger multi-state utility holding companies for customers, but does compete with them and other infrastructure investors for capital, equity-financing terms, and (via Midstream) co-investment opportunities in interstate pipeline projects.

4. Strategic Strengths & Risks

Strengths

• Regulated monopoly with multi-year franchise certainty: Exclusive franchises running through 2035 provide a highly visible, long-duration revenue base free from direct distribution competition.
• Earnings-stabilizing rate mechanisms: The PGA, WNA, SAVE, ICC, and RNG riders collectively reduce volatility from weather, commodity cost swings, and infrastructure investment timing — a structurally de-risked earnings profile typical of well-regulated gas utilities.
• Long operating history and deep community entrenchment: Operating continuously since 1883, Roanoke Gas has over a century of infrastructure, regulatory relationships, and customer trust embedded in its single-state franchise.
• Pipeline investment optionality: The Mountain Valley Pipeline equity stake provides incremental, differentiated earnings exposure beyond the core local-distribution rate base.

Risks

• Small scale and single-region concentration: With only 106 employees and a single-state, single-metro service territory, RGC Resources lacks the scale and geographic diversification of larger gas utility holding companies, concentrating all regulatory and economic risk in one Virginia SCC jurisdiction.
• Long-term decarbonization and electrification risk: The company's own disclosure flags growing competition from solar and wind, reflecting a broader structural risk that policy-driven electrification trends could gradually erode natural gas demand over multi-decade time horizons.
• Regulatory lag and rate-case risk: Although rate mechanisms smooth some volatility, the company still depends on periodic Virginia SCC rate case outcomes to recover capital investment and earn an adequate return, creating episodic regulatory risk.
• Concentration in industrial/commercial fuel-switching customers: Industrial customers with fuel flexibility can switch away from natural gas when relative pricing favors alternatives, creating some demand elasticity despite the utility's monopoly franchise.
• Pipeline project risk via Midstream: Returns on the Mountain Valley Pipeline and related Southgate/Boost investments depend on the operational and regulatory performance of projects RGC Resources does not control, given its minority ownership stakes.

Summary Conclusion

RGC Resources is a small, highly stable regulated natural gas utility holding company whose Roanoke Gas subsidiary has served the same Virginia community for well over a century under an exclusive municipal franchise structure that runs through 2035. The combination of a monopoly service territory, multiple SCC-approved rate-stabilization mechanisms, and a supplemental Mountain Valley Pipeline equity investment gives the company a predictable, low-volatility earnings profile well suited to income-oriented investors, evidenced by steady EPS growth from $1.16 to $1.29 in fiscal 2025. The principal long-term risk is not near-term competitive displacement — the franchise structure largely precludes that — but the multi-decade secular question of whether electrification and renewable-energy adoption gradually erode natural gas demand in its service territory, a risk the company itself explicitly acknowledges in its own disclosures.
