Net income for the third quarter of 2025 was $19.4 million ($0.82 per share) compared to $17.5 million ($0.78 per share) in the third quarter of 2024. Excluding transaction and transition-related expenses associated with the acquisition and integration of FCG, adjusted net income was $19.5 million ($0.82 per share) compared to $18.1 million ($0.80 per share) in the prior-year period. The adjusted EPS growth reflects a $0.04 per share impact from $92.0 million of equity issued over the last twelve months to restore the Company's equity to total capitalization ratio closer to the target ratio.

Adjusted earnings for the third quarter of 2025 were largely driven by contributions from regulatory initiatives and infrastructure programs, organic growth in the natural gas distribution businesses and pipeline expansion projects driven by natural gas demand, and increased compressed natural gas (CNG), renewable natural gas (RNG) and liquified natural gas (LNG) services.

During the first nine months of 2025, net income was $94.2 million ($4.03 per share) compared to $81.9 million ($3.66 per share) in the prior-year period. Excluding the transaction and transition-related expenses, adjusted net income was $94.9 million ($4.06 per share) compared to $84.2 million ($3.76 per share) in the prior-year period. This resulted in EPS and adjusted EPS growth of 10.1 percent and 8.0 percent, respectively, compared to the prior-year period.

Year-to-date adjusted earnings for 2025 were primarily impacted by the factors discussed for the third quarter as well as additional adjusted gross margin from increased customer consumption experienced earlier in the year.

“Our performance in the third quarter of 2025 demonstrated continued operational excellence across our businesses to serve our customers and communities. In both the quarter and the year-to-date periods, we delivered double-digit growth in Adjusted Gross Margin and Operating Income relative to the prior year and we continued to strengthen our balance sheet with incremental long-term debt and equity issuances during the quarter,” said Jeff Householder, the Company's Chair of the Board, President and Chief Executive Officer.

“These results demonstrate that we continue to deliver on our three growth pillars. Within the third quarter, we invested $123 million of capital and generated over $20 million of gross margin from transmission, infrastructure, and transportation projects. We also reached final completion of our Delaware rate case, with a settlement on tariff-related changes, including rate design. And finally, we took the next pivotal step in our continuous business transformation efforts, including officially kicking off our multi-year Enterprise Resource Plan (ERP) process, which was a primary driver in the increase and extension of our 2025 capital guidance to $425-$450 million. We remain focused on achieving our earnings and increased capital guidance in 2025, demonstrating record performance and reaching new heights of growth for the Company.”

Earnings and Capital Investment Guidance

The Company continues to re-affirm its 2025 EPS guidance range of $6.15 to $6.35 per share, pending a successful outcome of the FCG excess depreciation filing. Given the Company's progress on a multitude of capital projects, the Company is further increasing and refining its 2025 capital guidance range to $425 million to $450 million.

Looking to the future, the Company also continues to re-affirm its 2028 EPS guidance range of $7.75 to $8.00 per share, as well as its capital expenditure guidance range for the five-year period ending 2028 of $1.5 billion to $1.8 billion.

*Unless otherwise noted, EPS and Adjusted EPS information are presented on a diluted basis.

Non-GAAP Financial Measures

**This press release including the tables herein, include references to both Generally Accepted Accounting Principles (“GAAP”) and non-GAAP financial measures, including Adjusted Gross Margin, Adjusted Net Income and Adjusted EPS. A “non-GAAP financial measure” is generally defined as a numerical measure of a company's historical or future performance that includes or excludes amounts, or that is subject to adjustments, so as to be different from the most directly comparable measure calculated or presented in accordance with GAAP. The Company's management believes certain non-GAAP financial measures, when considered together with GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any particular period.

The Company calculates Adjusted Gross Margin by deducting the purchased cost of natural gas, propane and electricity and the cost of labor spent on direct revenue-producing activities from operating revenues. The costs included in Adjusted Gross Margin exclude depreciation and amortization and certain costs presented in operations and maintenance expenses in accordance with regulatory requirements. The Company calculates Adjusted Net Income and Adjusted EPS by deducting costs and expenses associated with significant acquisitions that may affect the comparison of period-over-period results. These non-GAAP financial measures are not in accordance with, or an alternative to, GAAP and should be considered in addition to, and not as a substitute for, the comparable GAAP measures. The Company believes that these non-GAAP measures are useful and meaningful to investors as a basis for making investment decisions, and provide investors with information that demonstrates the profitability achieved by the Company under allowed rates for regulated energy operations and under the Company's competitive pricing structures for unregulated energy operations. The Company's management uses these non-GAAP financial measures in assessing a business unit and Company performance. Other companies may calculate these non-GAAP financial measures in a different manner.

The following tables reconcile Gross Margin, Net Income, and EPS, all as defined under GAAP, to the Company's non-GAAP measures of Adjusted Gross Margin, Adjusted Net Income and Adjusted EPS for each of the periods presented.

Operating income for the third quarter of 2025 was $45.0 million, an increase of $4.1 million or 10.0 percent compared to the same period in 2024. Excluding transaction and transition-related expenses associated with the acquisition and integration ofFCG, operating income increased $3.5 million or 8.4 percentcompared to the prior-year period. The increase in adjusted gross margin in the third quarter of 2025 was driven by incremental margin from regulatory initiatives and infrastructure programs, pipeline expansion projects, increased CNG, RNG and LNG services and natural gas organic growth. The increase in operating expenses was driven largely by higher depreciation attributable to growth projects and the absence of a reserve surplus amortization mechanism (“RSAM”) adjustment from FCG (which represented a $3.2 million benefit in the third quarter of 2024). Higher expenses associated with facilities, maintenance and outside services compared to the prior-year period also contributed to the increase.

Operating results for the second and third quarters historically have been lower due to reduced customer demand during warmer periods of the year. The impact to operating income may not align with the seasonal variations in adjusted gross margin as many of the operating expenses are recognized ratably over the course of the year.

Operating income for the nine months ended September 30, 2025 was $182.1 million, an increase of $20.8 million or 12.9 percent compared to the same period in 2024. Excluding transaction and transition-related expenses associated with the acquisition and integration of FCG, operating income increased $18.7 million or 11.4 percentcompared to the prior-year period. The increase in adjusted gross margin in the first nine months of 2025 was driven by incremental margin from regulatory initiatives and infrastructure programs, increased CNG, RNG and LNG services, pipeline expansion projects and natural gas organic growth, and increased customer consumption resulting from year-over-year colder temperatures in the Company's Mid-Atlantic and Ohio service territories. These increases were partially offset by lower margins per gallon and related fees in the Company's propane distribution business and a reduced volume of off-system sales and service fees in its natural gas business. Higher operating expenses were driven largely by the absence of an RSAM adjustment from FCG (which represented an $8.9 million benefit during the nine months ended September 30, 2024) and higher depreciation attributable to growth projects. Higher facilities, maintenance and outside services, insurance, and payroll, benefits and other employee-related expenses compared to the prior-year period also contributed to the increase.

Recently Completed and Ongoing Major Projects and Initiatives

The Company continuously pursues and develops additional projects and regulatory initiatives to serve existing and new customers, further grow its businesses and earnings, and increase shareholder value. The following table includes all major projects and initiatives that are currently underway or recently completed. The Company's practice is to add incremental margin associated with new projects and regulatory initiatives to this table once negotiations or details are substantially final and/or the associated earnings can be estimated. Major projects and initiatives that have generated consistent year-over-year adjusted gross margin contributions are removed from the table at the beginning of the next calendar year.

Detailed Discussion of Major Projects and Initiatives

Pipeline Expansions

Worcester Resiliency Upgrade In August 2023, Eastern Shore filed an application with the Federal Energy Regulatory Commission (“FERC”) requesting authorization to construct the Worcester Resiliency Upgrade, which consists of a mixture of storage and transmission facilities in Sussex County, Delaware and Wicomico, Worcester, and Somerset Counties in Maryland. The project will provide long-term incremental supply necessary to support the growing demand of the participating shippers. In January 2025, the FERC approved the project. Construction has commenced and the project is expected to be placed into service in mid-2026 dependent on final FERC approval.

In June 2025, Eastern Shore filed a limited amended application with the FERC requesting revised initial transportation rates for the project. The revised rates reflected increased capital costs associated with unanticipated changes in global markets and supply chains, including the availability of skilled laborers with the requisite certifications to work on this project. Eastern Shore requested expedited action by the FERC in relation to this matter and an approved order was issued in July 2025. The project is expected to generate $10.2 million in adjusted gross margin in 2026 and $17.6 million in 2027 and thereafter.

East Coast Reinforcement Projects (Boynton Beach and New Smyrna Beach) In December 2023, Peninsula Pipeline filed a petition with the Florida Public Service Commission (“PSC”) for approval of its Transportation Service Agreements with Florida Public Utilities Company (“FPU”) for projects that will provide additional supply to coastal communities on the East Coast of Florida, which are experiencing significant population growth. Peninsula Pipeline proposed several pipeline extensions to support FPU's distribution system in the areas of Boynton Beach and New Smyrna Beach with an additional 15,000 Dts/day and 3,400 Dts/day, respectively. The Florida PSC approved the projects in March 2024. New Smyrna Beach was placed into service during May 2025 and construction is projected to be complete for Boynton Beach in the fourth quarter of 2025.

Central Florida Reinforcement Projects (Plant City and Lake Mattie) In February 2024, Peninsula Pipeline filed a petition with the Florida PSC for approval of its Transportation Service Agreements with FPU for projects that will support additional supply to communities located in Central Florida which are also experiencing significant population growth. Peninsula Pipeline proposed to construct several pipeline extensions which will support FPU's distribution system around the Plant City and Lake Mattie areas of Florida with an additional 5,000 Dts/day and 8,700 Dts/day, respectively. The Florida PSC approved the projects in May 2024. The Plant City project was completed in the fourth quarter of 2024, and the Lake Mattie project went into service in July 2025.

Renewable Natural Gas Supply Projects In February 2024, Peninsula Pipeline filed a petition with the Florida PSC for approval of Transportation Service Agreements with FCG for projects that will support the transportation of additional renewable energy supply to FCG. The projects, located in Florida's Brevard, Indian River and Miami-Dade counties, will bring renewable natural gas produced from local landfills into FCG's natural gas distribution system. Peninsula Pipeline will construct several pipeline extensions which will support FCG's distribution system in Brevard County, Indian River County, and Miami-Dade County. Benefits of these projects include increased gas supply to serve expected FCG growth, strengthened system reliability and additional system flexibility. The Florida PSC approved the petition at its July 2024 meeting with the projects estimated to be completed in the first half of 2026. In October 2025, the Florida PSC approved amendments to the Transportation Service Agreements that were filed to include Peninsula Pipeline as a party to the related interconnection agreements.

Miami Inner Loop Pipeline Projects In September 2024, Peninsula Pipeline filed a petition with the Florida PSC for approval of the Transportation Service Agreement with FCG for a series of projects that will enhance the infrastructure in Miami-Dade County. The proposed expansion consists of the development of several pipeline projects to support growth and FCG's distribution system in the area, as well as enhance FCG's access to obtain gas from various points in the Miami-Dade County area. The expansion was approved in February 2025 and interim services began in August 2025 with permanent facilities expected to be in service by the second quarter of 2026.

Duncan Plains Pipeline Project In July 2025, Aspire Energy Express entered into an agreement with American Electric Power to construct and operate an intrastate natural gas pipeline in central Ohio to serve a new fuel-cell facility, which will provide on-site electric power to a data center. This new transmission infrastructure is expected to be in service in the first half of 2027.

Regulatory Initiatives

Maryland Natural Gas Rate Case In January 2024, the Company's natural gas distribution businesses in Maryland, CUC-Maryland Division, Sandpiper Energy, Inc., and Elkton Gas Company (collectively, the “Maryland natural gas distribution businesses”) filed a joint application for a natural gas rate case with the Maryland PSC. In connection with the application, the Company sought approval of the following: (i) permanent rate relief of approximately $6.9million with a return on equity (“ROE”) of 11.5 percent; (ii) authorization to make certain changes to tariffs to include a unified rate structure and to consolidate the Maryland natural gas distribution businesses; and (iii) authorization to establish a rider for recovery of the costs associated with the Company's new technology systems. In August 2024, the Maryland natural gas distribution businesses, the Maryland Office of People's Counsel (the “Maryland OPC”) and PSC staff reached a settlement which provided for, among other things, an increase in annual base rates of $2.6 million. In September 2024, the Maryland Public Utility Judge issued an order approving the related settlement agreement in part. The $2.6 million increase in annual base rates was approved and the Company filed a Phase II filing in November 2024 to determine rate design across the Maryland natural gas distribution businesses, consolidation of the applicable tariffs and recovery of technology costs. The hearing was held in March 2025, during which Phase II was approved, including an additional $0.9 million in revenue requirement, for a total cumulative increase of $3.5 million. A final order was issued in April 2025 and included approval of the consolidation of the operations and the assets of CUC-Maryland Division, Sandpiper Energy, and Elkton Gas into one entity which was renamed and will operate as Chesapeake Utilities of Maryland, Inc.

Maryland Natural Gas Depreciation Study In January 2024, the Company's natural gas distribution businesses in Maryland filed a joint petition for approval of its proposed unified depreciation rates with the Maryland PSC. A settlement among the Company, PSC staff and the Maryland OPC was reached and the final order approving the related settlement agreement went into effect in July 2024, with new depreciation rates effective as of January 1, 2023. The approved depreciation rates resulted in an annual reduction in depreciation expense of approximately $1.2 million.

Delaware Natural Gas Rate Case In August 2024, the Company's Delaware natural gas division filed an application for a natural gas rate case with the Delaware PSC seeking approval of the following: (i) permanent rate relief of approximately $12.1 million with a ROE of 11.5 percent; (ii) proposed changes to depreciation rates which were part of a depreciation study also submitted with the filing; and (iii) authorization to make certain changes to tariffs. Annualized interim rates were approved by the Delaware PSC in the amount of $2.5 million and became effective in October 2024. A settlement among the Company, PSC staff and the Delaware Division of the Public Advocate was reached and approved by the Delaware PSC in June 2025 providing an annual revenue increase of $6.1 million, as well as dividing the rate case into two phases. Rates set to recover the approved components of the increase were effective in March 2025. In October 2025, a settlement among the Company, PSC staff and the Delaware Division of the Public Advocate was reached for Phase II of the rate case addressing tariff-related changes including rate design and approved by the Delaware Public Service Commission with rates effective as of October 15, 2025.

FPU Electric Rate Case In August 2024, the Company's Florida Electric division filed a petition with the Florida PSC seeking a general base rate increase of $12.6 million with a ROE of 11.3 percent based on a 2025 projected test year. Annualized interim rates of approximately $1.8 million were approved with an effective date of November 1, 2024. In March 2025, the Florida PSC approved the permanent rate increase, but the order was subsequently protested. In May 2025, the Company reached a settlement agreement with the interested parties to resolve all outstanding issues in its current base rate case, which was filed as a joint motion for approval with the Florida PSC. This settlement which was approved by the Florida PSC in July 2025, provides for a total revenue increase of approximately $8.6 million on an annual basis, with $1.0 million of the increase deferred from the first year's base rate increase and recovered over three years. A step-up rate increase was also approved for up to $0.7 million, upon completion of the purchase and refurbishment of certain substations, which is expected in December 2026.

FCG Depreciation Study In February 2025, FCG filed a depreciation study with the Florida PSC. The application is requesting approval of revised annual depreciation rates, as well as a reduction related to a reserve imbalance that would be amortized over a two-year period. The outcome of the application is subject to review and approval by the Florida PSC. The Florida OPC filed a motion to hold this filing in abeyance, which was denied in April 2025. The OPC has since filed motions to reconsider and dismiss the docket, which were denied by the Florida PSC in September 2025. At this time, the docket is set for hearing in December 2025.

Other Major Factors Influencing Adjusted Gross Margin

Weather and Consumption For the nine months ended September 30, 2025, increased customer consumption, which includes the effects of colder weather conditions, largely in the Company's Ohio and Delmarva service areas, compared to the prior-year period resulted in a $4.8 million increase in adjusted gross margin.

The following table summarizes heating degree-day (HDD) and cooling degree-day (CDD) variances from the 10-year average HDD/CDD (“Normal”) for the three and nine months ended September 30, 2025 and 2024.
