**MIDDLESEX WATER COMPANY**

**NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1 – Basis of Presentation and Recent Developments**

Middlesex Water Company (Middlesex or the Company) is the parent company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Utility Service Affiliates, Inc. (USA), and Utility Service Affiliates (Perth Amboy) Inc. (USA-PA). Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh) are wholly-owned subsidiaries of Tidewater. Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), previously subsidiaries of Middlesex, were merged into Middlesex effective April 1, 2026 (for further information, see Note 2, *Rates and Regulatory Matters)*. The financial statements for Middlesex and its wholly-owned subsidiaries are reported on a consolidated basis. All significant intercompany accounts and transactions have been eliminated.

The consolidated notes within the 2025 Annual Report on Form 10-K (the 2025 Form 10-K) are applicable to these financial statements and, in the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary (including normal recurring accruals) to fairly state the Company's financial position as of March 31, 2026, and the results of operations and cash flows for the three month periods ended March 31, 2026 and 2025. Information included in the Condensed Consolidated Balance Sheet as of December 31, 2025, has been derived from the Company's December 31, 2025 audited financial statements included in the 2025 Form 10-K.

**Note 2 – Rates and Regulatory Matters**

***Middlesex Rate Matters***

In February 2026, the New Jersey Board of Public Utilities (NJBPU) approved the settlement agreement in our general base rate application between Middlesex and Pinelands, NJBPU Staff and the New Jersey Division of Rate Counsel, with new rates effective February 23, 2026. The NJBPU order approved an increase in our annual operating revenues by $14.5 million based on an authorized return on common equity of 9.6% and a common equity ratio of 54.25%. Included in the settlement agreement, Middlesex and Pinelands customers received a one-time bill credit in the first quarter of 2026 totaling $3.3 million for the overcollection of New Jersey Gross Receipts Taxes. In addition, beginning in late February 2026, Middlesex customers will receive a $3.3 million credit over 12 months from the proceeds of a multi-district litigation (MDL) settlement agreement between Middlesex and manufacturers of Perfluoroalkyl Substances (PFAS) (for further information on the MDL settlement, see *MDL Settlement* below).

In February 2026, the NJBPU approved the joint petition filed by Middlesex and Pinelands for a Resiliency and Environmental System Improvement Charge (RESIC) Foundational Filing for the three-year period ending October 2028. The program allows for the recovery of certain costs of investments that further maintain, enhance, or improve the resiliency, health, safety, or environmental protection for Middlesex and Pinelands customers or broader public health. RESIC activities include compliance with requirements to address existing and emerging chemical elements and compounds, treatment media and related equipment, installation of new plant or equipment, or replacement of existing plant or equipment. Under the RESIC program, Middlesex and Pinelands submit semi-annual surcharge filings to the NJBPU for qualifying capital investments completed every six months to be recovered up to $3.6 million or 2.5% of total annual revenues included in their February 2026 base rate increase.

In February 2026, the NJBPU approved the joint petition filed by Middlesex and Pinelands Water for a Distribution System Improvement Charge (DSIC) Foundational Filing, which allows for the recovery of investments in qualifying capital improvements to their water distribution system for the three-year period ending October 2028. Under the DSIC program, Middlesex and Pinelands Water submit semi-annual surcharge filings to the NJBPU for qualifying capital investments completed every six months to be recovered up to $7.1 million or 5% of total annual revenues included in their February 2026 base rate increase.

In January 2026, the NJBPU approved the joint petition filed by Middlesex, Pinelands Water and Pinelands Wastewater to consolidate the three entities into Middlesex through a corporate reorganization. The merger of Pinelands Water and Pinelands Wastewater into Middlesex is expected to deliver operational efficiencies and enhanced benefits for customers across multiple areas. The merger has been finalized and was effective on April 1, 2026.

In November 2025, the NJBPU approved the fourth Middlesex DSIC rate, effective December 1, 2025 that was expected to result in $0.9 million of annual revenues, which is in addition to the existing $2.3 million of annual revenues from previous DSIC filings. Middlesex's DSIC rate reset to zero in connection with Middlesex's February 2026 base rate increase.

The NJBPU-approved Middlesex Lead Service Line Replacement (LSLR) Plan continues, and costs of $0.4 million for replacing customer-owned lead service lines incurred from January 2025 through June 2025 were recovered between September 2025 and February 2026. Costs of $0.3 million incurred from July 2025 through December 2025 are expected to be recovered between March 2026 and August 2026. The LSLR surcharge is required to be reset every six months over the life of the LSLR Plan. Cost recovery for replacing Company-owned lead service lines are recoverable through traditional rate making in connection with general rate case filings.

***Tidewater Rate Matters***

In February 2026, the Delaware Public Service Commission (DEPSC) approved the March 2026 refund of $1.1 million to Tidewater customers resulting from the proceeds of the MDL settlement agreement between Tidewater and manufacturers of PFAS. For further information, see discussion in *MDL Settlement* below.

In January 2026, Tidewater completed the acquisition of the water utility assets of Pinewood Acres, LLC, as approved by the DEPSC, for $0.2 million. Pinewood Acres serves approximately 350 customers in Kent County, Delaware.

In December 2025, the DEPSC approved the Tidewater DSIC rate, effective January 1, 2026. Tidewater is expected to recover approximately $0.3 million of semi-annual DSIC revenues between January 2026 and June 2026.

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

In July 2025, the DEPSC approved the settlement agreement in our general base rate application between Tidewater, DEPSC Staff and the Delaware Division of the Public Advocate, with new rates effective July 3, 2025. The DEPSC order approved an increase in our annual operating revenues by $5.5 million based on an authorized return on common equity of 9.5% and a common equity ratio of 53.5%.

***MDL Settlement***

Multiple Company utility subsidiaries are parties to the aforementioned MDL lawsuit against manufacturers of certain PFAS for damages, contribution and reimbursement of costs incurred and continuing to be incurred to address the presence of such PFAS in public water supply systems owned and operated by these utility subsidiaries and throughout their service areas. Settlements with several defendants in the MDL have received final approval by the MDL court. The Company began receiving settlement payments in 2025, which will continue through 2026 and beyond. As of March 31, 2026, the Company received $6.0 million. Proceeds from these settlement payments have been and will likely continue to be shared with customers in the future (for further information on 2026 customer refunds related to the MDL settlement, see *Middlesex Rate Matters and Tidewater Rate Matters* above).

***Southern Shores Rate Matters***

Southern Shores provides water service to a 2,200 unit condominium community in Sussex County, Delaware under a DEPSC-approved agreement expiring December 31, 2029. Under the agreement, rates are increased annually by the lesser of the regional Consumer Price Index or 3%. Additionally, when there are unanticipated capital expenditures or regulatory related changes in operating expenses exceed certain annual thresholds, rates are increased. In 2024, capital expenditures did exceed the established threshold. Effective January 1, 2025, Southern Shores rates were increased $0.1 million or 6.51%. In 2025, Southern Shores capital expenditures exceeded the established threshold. Effective January 1, 2026, Southern Shores rates were increased $0.1 million or 4.89%.

**Note 3 – Capitalization**

Sales of shares of common stock and issuance of long-term debt are part of the Company's comprehensive financing plan to fund its multi-year utility plant infrastructure investment program.

***Common Stock*** 

During the three months ended March 31, 2026 and 2025, there were 4,025 common shares (approximately $0.2 million) and 4,228 common shares (approximately $0.2 million), respectively, issued under the Middlesex Water Company Investment Plan.

In May 2025, Middlesex entered into an At-the-Market (ATM) Equity Offering Sales Agreement (Equity Sales Agreement) with BofA Securities, Inc., Robert W. Baird & Co. Incorporated and Janney Montgomery Scott LLC (Janney), pursuant to which Middlesex may offer and sell shares of its common stock, no par value per share, from time to time in "at-the-market" offerings, having an aggregate gross sales price of up to $110.0 million. As of February 20, 2026, the Equity Sales Agreement was amended, replacing Janney with Huntington Securities, Inc. as a sales agent. The Company intends to use the net proceeds from these sales, after deducting commissions and offering expenses, to fund our capital expenditures, to purchase and maintain plant equipment, as well as for other general corporate purposes. For the three months ended March 31, 2026, Middlesex issued and sold a total of 49,305 shares of common stock, at a weighted average price of $54.82 per share, and received $2.7 million in net proceeds, under the Equity Sales Agreement. As of March 31, 2026, the Company had $77.3 million of aggregate gross sales remaining under the Equity Sales Agreement.

***Long-term Debt*** 

Subject to regulatory approval, the Company periodically issues long-term debt to fund its investments in utility plant. To the extent possible and fiscally prudent, the Company finances qualifying capital projects under State Revolving Fund (SRF) loan programs in New Jersey and Delaware. These government programs provide financing at interest rates typically below rates available in the broader financial markets.

In September 2024, Tidewater closed on a $2.2 million Delaware SRF loan with a 0.0% interest rate with maturity dates in 2044. This loan is for costs associated with Tidewater's obligation, as required by federal law and Delaware regulations, to

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

identify and inventory lead service lines throughout Tidewater's service area. Tidewater has drawn down $1.8 million as of March 31, 2026 and expects that the requisitions will continue through 2026.

In May 2024, Tidewater closed on four Delaware SRF loans totaling $5.6 million, all at interest rates of 2.0% with maturity dates in 2044. These loans are for the construction, relocation, improvement, and/or interconnection of transmission mains and construction of a water treatment facility. In December 2025, Tidewater closed on an additional $1.0 million, 2.0% SRF loan with a maturity date of 2045 related to these projects. Tidewater has drawn down $2.1 million on these loans as of March 31, 2026. Each project has its own construction timetable with the last spending set to occur in 2027.

In December 2025, Southern Shores closed on a $0.4 million Delaware SRF loan with a 0.0% interest rate with a maturity date in 2045. This loan is for costs associated with Southern Shore's obligation, as required by federal law and Delaware regulations, to identify and inventory lead service lines in its service area. As of March 31, 2026, Southern Shores has drawn down $0.2 million on these loans.

In February 2026, Pinelands Water and Pinelands Wastewater repaid in full $3.7 million and $3.4 million, respectively, of their amortizing secured notes. The interest rates and due dates on both of these notes were 6.17% and 2043, respectively.

***Fair Value of Financial Instruments*** 

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments for which it is practicable to estimate that value. The carrying amounts reflected in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and notes payable approximate their respective fair values due to the short-term maturities of these instruments. The fair value of First Mortgage Bonds (FMBs) and SRF Bonds (collectively, the Bonds) issued by Middlesex is based on quoted market prices for similar issues. Under the fair value hierarchy, the fair value of cash and cash equivalents is classified as a Level 1 measurement and the fair value of notes payable and the FMBs in the table below are classified as Level 2 measurements. The carrying amount and fair value of the FMBs were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **(Thousands of Dollars)** | **(Thousands of Dollars)** | **(Thousands of Dollars)** | **(Thousands of Dollars)** |
| | **March 31, 2026** | **March 31, 2026** | **December 31, 2025** | **December 31, 2025** |
| | **Carrying<br>Amount** | **Fair<br>Value** | **Carrying<br>Amount** | **Fair<br>Value** |
| FMBs | $125431 | $119770 | $126172 | $120430 |

---

It was not practicable to estimate the fair value on our outstanding long-term debt for which there is no quoted market price and there is not an active trading market. For details, including carrying value, interest rates and due dates on these series of long-term debt, please refer to those series noted as "Secured Notes" and "State Revolving Trust Notes" on the Condensed Consolidated Statements of Capital Stock and Long-Term Debt. The carrying amount of these instruments was $252.8 million and $259.5 million at March 31, 2026 and December 31, 2025, respectively. Advances for construction have carrying amounts of $26.0 million and $25.5 million at March 31, 2026 and December 31, 2025, respectively. Their relative fair values cannot be accurately estimated since future refund payments depend on several variables, including new customer connections, customer consumption levels and future rate increases.

Substantially all of the utility plant of the Company is subject to the lien of its mortgage, which includes debt service and capital ratio covenants. The Company is in compliance with all of its mortgage covenants and restrictions.

**Note 5 – Business Segment Data**

The Company's Chief Operating Decision Maker (CODM) consists of the Company's Chief Executive Officer, Chief Financial Officer, and Chief Operating Officer. The CODM evaluates segment performance and profitability using net income. This metric provides a clear, consistent basis for analyzing the financial results of each segment and supports decision-making regarding the allocation of resources.

Resource allocation to the Company's regulated and non-regulated segments begins with the annual budgeting process, which establishes initial funding and resource levels for each segment. The budget incorporates key financial and operational inputs, including anticipated revenues, expenses, capital and financing requirements, aligning with the Company's strategic objectives and regulatory obligations. The CODM reviews budget-to-actual variances on a monthly, quarterly and year to-date basis and makes interim decisions to reallocate resources among segments as needed, ensuring a timely and effective response to changing conditions. For the regulated segment, the CODM uses this assessment to determine whether the segment is achieving its regulatory authorized rate of return.

The segments follow the same accounting policies as described in Note 1 – Organization, Summary of Significant Accounting Policies and Recent Developments of the 2025 Form 10-K. Segment profit or loss is based on Net Income. Expenses used to determine operating income before taxes are charged directly to each segment or are allocated based on the applicable cost allocation factors. Assets allocated to each segment are based upon specific identification of such assets provided by Company records. The effects of all intra-segment and/or intercompany transactions are eliminated in the consolidated financial statements.

The Company has identified two reportable segments. One is the regulated business of collecting, treating and distributing water on a retail and wholesale basis to residential, commercial, industrial and fire protection customers in parts of New Jersey and Delaware and includes Middlesex, Tidewater, Pinelands and Southern Shores. This segment also includes a regulated wastewater system in New Jersey, Pinelands Wastewater. The Company is subject to regulations as to its rates, services and other matters by the states of New Jersey and Delaware with respect to utility service within these states. The other segment is primarily comprised of non-regulated contract services for the operation and maintenance of municipal and private water and wastewater systems in New Jersey and Delaware and includes USA, USA-PA, and White Marsh.

In February 2026, the Company amended its line of credit with PNC Bank. Under the terms of the amendment, the expiration date was extended to January 31, 2029 and the maximum borrowing amount was increased to $100 million.

The maturity dates for the Notes Payable as of March 31, 2026 are all three months or less and are extendable at the discretion of the Company.

The interest rates are set for borrowings under the Bank of America and PNC Bank lines of credit using the Secured Overnight Financing Rate (SOFR) and then adding a specific financial institution credit spread. The interest rate for borrowings under the CoBank line of credit are set weekly using CoBank's internal cost of funds index that is similar to the SOFR and adding a credit spread. There is no requirement for a compensating balance under any of the established lines of credit.

The weighted average interest rate on the outstanding borrowings at March 31, 2026 under these credit lines is 4.87%.

The weighted average daily amounts of borrowings outstanding under these credit lines and the weighted average interest rates on those amounts were as follows:

**Note 7 – Commitments and Contingent Liabilities**

*Water Supply* – Middlesex's agreement with the New Jersey Water Supply Authority (NJWSA) for the purchase of untreated water expires November 30, 2048. NJWSA provides for an average purchase of 27.0 million gallons a day (mgd) with a peak up to 47.0 mgd. Pricing is set annually by the NJWSA through a public rate making process. The agreement has provisions for additional pricing in the event Middlesex overdrafts or exceeds certain monthly and annual thresholds.

Middlesex also has an agreement with a non-affiliated NJBPU-regulated water utility for the purchase of treated water. This agreement, which expires February 27, 2031, provides for the minimum purchase of 3.0 mgd of treated water with provisions for additional purchases if needed.

Tidewater contracts with the City of Dover in Delaware to purchase treated water of up to 75.0 million gallons annually.

**Construction** – In connection with the Company's planned capital expenditures, the Company has entered into several contractual construction agreements that in total obligate it to expend an estimated $42.3 million in the future. The actual amount and timing of capital expenditures is dependent on the need for replacement of existing infrastructure, customer growth, residential new home construction and sales, project scheduling, supply chain and continued refinement of project scope and costs.

**Contingencies –** Based on our operations in the heavily-regulated water and wastewater industries, the Company is routinely involved in disputes, claims, lawsuits and other regulatory and legal matters, including responsibility for fines and penalties relative to regulatory compliance. At this time, Management does not believe the final resolution of any such matters, whether asserted or unasserted, will have a material adverse effect on the Company's financial position, results of

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

operations or cash flows. In addition, the Company maintains business insurance coverage that may mitigate the effect of any current or future loss contingencies.

**Change in Control Agreements –** The Company has Change in Control Agreements with its executive officers that provide compensation and benefits in the event of termination of employment under certain conditions in connection with a change in control of the Company.

**Note 8 – Employee Benefit Plans**

***Pension Benefits***

The Company's Pension Plan covers all active employees hired prior to April 1, 2007. Employees hired after March 31, 2007 are not eligible to participate in this plan, but can participate in a defined contribution profit sharing plan that provides an annual contribution at the discretion of the Company, based upon a percentage of the participants' annual paid compensation. For each of the three-month periods ended March 31, 2026 and 2025, the Company did not make cash contributions to the Pension Plan. The Company expects to make cash contributions of approximately $0.9 million over the remainder of the current year.

***Other Benefits***

The Company's Other Benefits Plan covers substantially all of its current retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance. For each of the three-month periods ended March 31, 2026 and 2025, the Company did not make cash contributions to its Other Benefits Plan. The Company expects to make additional Other Benefits Plan cash contributions of $1.1 million over the remainder of the current year.

**Note 9 – Revenue Recognition from Contracts with Customers**

The Company's revenues are primarily generated from regulated tariff-based water and wastewater utility services and non-regulated operation and maintenance contracts for services on water and wastewater systems owned by others. Revenue from contracts with customers is recognized when control of a promised good or service is transferred to customers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services.

The Company's regulated revenue results from tariff-based water and wastewater services to residential, industrial, commercial, fire-protection and wholesale customers. Residential customers are billed monthly or quarterly while most industrial, commercial, fire-protection and wholesale customers are billed monthly. Payments by customers are due between 15 and 30 days after the invoice date. Revenue is recognized as the water and wastewater services are delivered to customers which includes an accrual of unbilled revenues estimated from the last meter reading date to the end of the accounting period utilizing factors such as historical customer data and regional weather indicators. Unearned Revenues

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

and Advance Service Fees include fixed service charge billings in advance to Tidewater customers recognized as service is provided to the customer.

Non-regulated service contract revenues consist of base service fees, as well as fees for additional billable services provided to customers. Fees are billed monthly and are due within 30 days after the invoice date. The Company considers the amounts billed to represent the value of these services provided to customers. These contracts expire at various times through 2032 and contain remaining performance obligations for which the Company expects to recognize revenue in the future. These contracts also contain termination provisions.

Substantially all of the amounts included in operating revenues and accounts receivable are from contracts with customers.

The Company's contracts do not contain any significant financing components.

The Company's operating revenues are comprised of the following:

| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |

**Note 10 – Income Taxes**

The Company's effective tax rate was 10.8% and 10.9% for the three months ended March 31, 2026 and 2025 respectively. We evaluate and update our annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Income Taxes for the three months ended March 31, 2026 increased by $0.1 million from the same period in 2025, primarily due to higher pre-tax income.

The statutory Federal tax rate is 21.0% for each of the three months ended March 31, 2026 and 2025. For states with a corporate net income tax, the state corporate net income tax rates range from 8.7% to 9.0% for each of the three months ended March 31, 2026 and 2025. Our effective tax rate differs from the federal statutory tax rate primarily due to the recognition of the income tax benefits for the immediate deduction of repair expenditures on tangible property in the Middlesex System as well as other permanent book-to-tax differences.

**Overview**

Middlesex Water Company (Middlesex or the Company) has operated as a water utility in New Jersey since 1897 and in Delaware through our wholly-owned subsidiary, Tidewater Utilities, Inc. (Tidewater), since 1992. We are in the business of providing an essential water utility service for domestic, commercial, municipal, industrial and fire protection purposes. We operate water and wastewater systems under contract for governmental entities and private entities primarily in New Jersey and Delaware and provide regulated wastewater services in New Jersey. We are regulated by state public utility commissions as to rates charged to customers for water and wastewater services, as to the quality of water and wastewater service we provide and as to certain other matters in the states in which our regulated subsidiaries operate. Only our Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy), Inc. (USA-PA) and White Marsh Environmental Services, Inc. (White Marsh) subsidiaries are not regulated public utilities as related to rates and services quality. All municipal or commercial entities whose utility operations are managed by these entities, however, are subject to environmental regulation at the federal and state levels.

Our principal New Jersey water utility system (the Middlesex System) provides water services to approximately 61,000 retail customers, primarily in central New Jersey. The Middlesex System also provides water sales under contract to municipalities in central New Jersey with a total population of over 0.2 million. Prior to April 1, 2026, Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands) provided water and wastewater services to approximately 2,500 customers in Southampton Township, New Jersey. Effective April 1, 2026, Pinelands was merged into Middlesex and those customers are now served by Middlesex.

Our Delaware subsidiaries, Tidewater and Southern Shores Water Company, LLC, provide water services to approximately 65,000 retail customers in New Castle, Kent and Sussex Counties, Delaware. Tidewater's subsidiary, White Marsh, serves approximately 3,700 households in Kent and Sussex Counties through various operations and maintenance contracts.

USA-PA operates the water and wastewater systems for the City of Perth Amboy, New Jersey (Perth Amboy) under a 10-year operations and maintenance contract expiring in 2028. In addition to performing day-to day operations, USA-PA is also responsible for emergency response and management of capital projects funded by Perth Amboy.

USA operates the Borough of Avalon, New Jersey's (Avalon) water utility, sewer utility and storm water system under a ten-year operations and maintenance contract expiring in 2032. USA also operates the Borough of Highland Park, New Jersey's (Highland Park) water and wastewater systems under a 10-year operations and maintenance contract expiring in 2030. In addition to performing day-to-day service operations, USA is responsible for emergency response and management of capital projects funded by Avalon and Highland Park.

Under a marketing agreement with HomeServe USA Corp. (HomeServe) expiring in 2031, USA offers residential customers in New Jersey and Delaware water and wastewater related services and home maintenance programs. HomeServe is a leading national provider of such home maintenance service programs. USA receives a service fee for the billing, cash collection and other administrative matters associated with HomeServe's service contracts. USA also provides unregulated water and wastewater services under contract with several New Jersey municipalities.

**Recent Developments**

**Perfluoroalkyl Substances (PFAS) Multi-District Litigation Settlement -** Multiple Company utility subsidiaries are parties to a multi-district litigation (MDL) lawsuit against manufacturers of certain PFAS for damages, contribution and reimbursement of costs incurred and continuing to be incurred to address the presence of such PFAS in public water supply systems owned and operated by these utility subsidiaries and throughout their service areas. Settlements with several defendants in the MDL have received final approval by the MDL court. The Company timely submitted to the MDL court its Phase One claim forms under settlement agreements with defendants 3M Company, DuPont de Nemours, Inc., Tyco Fire Products LP and BASF Corporation.

The settlement payments received by the Company will ultimately be refunded to customers. As of March 31, 2026, the Company received $6.0 million and anticipates receiving additional settlement payments during the remainder of 2026 from the defendants named above.

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

**Rates and Regulatory Matters** 

**Middlesex** - In February 2026, the New Jersey Board of Public Utilities (NJBPU) approved:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $14.5 million of base rate increases for Middlesex and Pinelands, effective February 23, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A Resiliency and Environmental System Improvement Charge (RESIC) Foundational Filing, which allows for the recovery of certain costs of future Middlesex and Pinelands investments related to compliance with requirements to address existing and emerging chemical elements or compounds, installation of new plant or equipment or replacement of existing plant or equipment to further maintain, enhance, or improve resiliency, health, safety or environmental protection; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A Distribution System Improvement System Charge (DSIC) Foundational Filing, which allows for the recovery of future Middlesex and Pinelands Water investments in qualifying capital improvements to their water distribution system.

In January 2026, the NJBPU approved the merger of Pinelands into Middlesex through a corporate reorganization, which was completed April 1, 2026.

**Tidewater** - In January 2026, Tidewater completed the acquisitions of the water utility assets of Pinewood Acres, LLC, as authorized by the Delaware Public Service Commission (DEPSC).

See Note 2, *Rates and Regulatory Matters* for more details about our rates and regulatory activity in Delaware and New Jersey.

**United States Environmental Protection Agency (USEPA) Issues PFAS Regulations** - In April 2024, the USEPA finalized drinking water regulations for PFAS, establishing maximum contaminant levels (MCLs) for three PFAS compounds (Regulated PFAS) that are lower than the current New Jersey Department of Environmental Protection MCLs adhered to by the Company. Under the new USEPA regulations, effective April 2024, water systems must monitor for Regulated PFAS and have three years to complete initial monitoring (by April 2027), followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of Regulated PFAS in their drinking water beginning in 2027. Water systems have five years (by April 2029) to implement solutions that reduce Regulated PFAS if monitoring shows that drinking water levels exceed these MCLs. The USEPA has announced its plans to issue a proposed rule extending the compliance date to 2031.

Beginning in April 2029 and absent an extension by the USEPA, water systems that have Regulated PFAS in drinking water which exceeds one or more of these MCLs must take action to reduce levels of these PFAS compounds in their drinking water and must provide notification to the public of the violation.

In anticipation of these new USEPA standards, in 2023, the Company began implementing its strategy to meet these lower MCLs for Regulated PFAS and is currently designing and implementing the most effective PFAS treatment approach.

**Capital Construction Program** - The Company's multi-year capital construction program encompasses numerous projects designed to upgrade and replace utility infrastructure as well as enhance the integrity and reliability of assets to better serve current and future generations of water and wastewater customers. The Company plans to invest approximately $126 million in 2026 in connection with this plan for projects that include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Upgrade of the Carl J. Olson Surface Water Treatment Plant (CJO Plant) to integrate PFAS removal from source

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;water and CJO Plant finished water pump electrical distribution system improvements in our Middlesex System;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Construction of new water treatment facilities, distribution system improvements and PFAS treatment facilities in

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Delaware; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Various water main replacements and improvements.

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

**Strategy for Growth**

Our strategy for selective and sustainable growth is focused on the following key areas:

• Invest in our utility infrastructure to build system resiliency and meet compliance requirements;

• Timely and adequate recovery of infrastructure investments and other costs to maintain and continually improve service quality;

• Selective acquisitions of investor and municipally-owned water and wastewater utilities; and

• Operation of municipal and industrial water and wastewater systems on a contract basis which meet our risk profile.

**Outlook**

The Company has projected to spend approximately $506 million for the 2026-2028 capital investment program, including approximately $255 million for upgrading our CJO Plant to integrate PFAS removal from source water, $34 million on the RENEW Program, which is our ongoing initiative to replace water mains in the Middlesex System, $17 million for replacement of a transmission main in Metuchen in our Middlesex System, $8 million for booster station generator replacement and electrical improvements, $9 million for construction of the Bethany Bay new water treatment facility in the Tidewater System and $12 million for elevated storage tanks in our Tidewater System.

The Company utilizes semi-annual DSIC and RESIC filings between general rate case filings to timely recover costs for qualified capital investments related to its utility systems as well as compliance with requirements to address existing and emerging chemical elements or compounds, installation of new plant or equipment or replacement of existing plant or equipment to further maintain and enhance resiliency, health, safety or environmental protection investments.

Overall, organic residential customer growth continues in our Tidewater system (approximately 3.0% in 2025) through expansion of our franchise area. However, current and evolving market conditions may challenge that growth.

The Company continues to seek "tuck-in" acquisition opportunities for small water systems near our current service areas

that are easily integrated into our Company, such as the recent acquisitions of the water utility assets of the Town of Ocean

View and Pinewood Acres, LLC in Delaware.

Our ability to increase operating income and net income is based significantly on four factors: weather, adequate and timely rate relief, effective cost management and customer growth. Weather patterns which can result in lower customer demand for water may occur at any time. Changes in customer water usage habits, as well as increases in capital expenditures and operating costs, are significant factors in determining the timing and extent of rate increase requests.

**Operating Results by Segment**

The discussion of the Company's operating results is on a consolidated basis and includes significant factors by subsidiary. The Company has two operating segments, Regulated and Non-Regulated. The operations of the Regulated segment are subject to regulations promulgated by state public utility commissions as to rates and level of service. Rates and level of service in the Non-Regulated segment are subject to the terms of individually-negotiated and executed contracts with municipal, industrial and other clients. Both segments are subject to federal and state environmental, water and wastewater quality and other associated legal and regulatory requirements.

The segments in the tables included below are comprised of the following companies: Regulated - Middlesex, Tidewater, Pinelands and Southern Shores; Non-Regulated - USA, USA-PA, and White Marsh.

*Operating Revenues*

Operating revenues for the three months ended March 31, 2026 increased $4.4 million from the same period in 2025 due to the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Middlesex System revenues increased $3.4 million due to increased wholesale customer demand, customer consumption and base rate increases effective February 23, 2026 (see Note 2, *Rates and Regulatory Matters*);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tidewater System revenues increased $0.8 million due to customer growth, increased customer consumption and rate increases (see Note 2, *Rates and Regulatory Matters*);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-regulated revenues increased $0.1 million, primarily due to higher supplemental contract services; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All other operating revenue categories increased $0.1 million.

*Operations and Maintenance Expense*

Operations and Maintenance Expense for the three months ended March 31, 2026 increased $1.9 million from the same period in 2025 due to increased variable production costs from higher production and higher labor cost due to wage and employee headcount increases, partially offset by higher capitalizable costs.

*Depreciation*

Depreciation expense for the three months ended March 31, 2026 increased $0.5 million from the same period in 2025 due to higher average utility plant in service.

*Other Taxes*

Other Taxes for the three months ended March 31, 2026 increased $0.5 million from the same period in 2025 primarily due to higher gross receipts taxes on higher revenues in our Middlesex system.

*Other Income, net*

Other Income, net for the three months ended March 31, 2026 increased $0.2 million from the same period in 2025 due to higher Allowance for Funds Used During Construction from increased capital expenditures.

*Interest Charges*

Interest Charges for the three months ended March 31, 2026 increased $0.5 million from the same period in 2025 primarily due to higher average debt outstanding.

*Income Taxes*

Income Taxes for the three months ended March 31, 2026 increased by $0.1 million from the same period in 2025, primarily due to higher pre-tax income.

**Liquidity and Capital Resources**

*Operating Cash Flows*

Cash flows from operations are largely based on four factors: weather, adequate and timely rate increases, effective cost management and customer growth. The effect of those factors on net income is discussed in *Results of Operations* above.

For the three months ended March 31, 2026, cash flows from operating activities decreased $2.1 million to $11.7 million. The decrease in cash flows from operating activities primarily resulted from higher vendor payments offset by the impact of Middlesex's approved base rate increase effective February 23, 2026 and Tidewater's base rate increase effective July 3, 2025.

*Investing Cash Flows*

For the three months ended March 31, 2026, cash flows used in investing activities increased $1.7 million to $20.6 million due to increased utility plant expenditures in 2026.

For further discussion on the Company's future capital expenditures and expected funding sources, see *Capital Expenditures and Commitments* below.

*Financing Cash Flows*

For the three months ended March 31, 2026, cash flows from financing activities increased $4.6 million to $8.2 million. The increase in cash flows provided by financing activities is due to higher long-term and short-term debt borrowings and the proceeds from the issuance of common stock under Middlesex's At-the-Market (ATM) equity offering program (for further information on Middlesex's ATM equity offering program, see below under *Capital Expenditures and Commitments)* partially offset by increased redemption of long-term-debt.

*Capital Expenditures and Commitments*

To fund our capital program, we use internally generated funds, short-term and long-term debt borrowings, proceeds from sales of common stock under the Middlesex Water Company Investment Plan and the ATM equity offering program, and when market conditions are favorable, proceeds from sales to the public of our common stock. To the extent possible and fiscally prudent, the Company finances qualifying capital projects under State Revolving Fund (SRF) loan programs in New Jersey and Delaware. These government programs provide financing at interest rates typically below rates available in the broader financial markets.

The NJBPU has approved Middlesex's petition to borrow up to $260.0 million during the period January 2026 through December 2028, in one or more negotiated transactions in the form of notes and/or first mortgage bonds through loans from the New Jersey SRF Program, the New Jersey Economic Development Authority, private placement and other financial institutions as needed.

In September 2024, Tidewater closed on a $2.2 million Delaware SRF loan with a 0.0% interest rate with maturity dates in 2044. This loan is for costs associated with Tidewater's obligation, as required by federal law and Delaware regulations, to identify and inventory lead service lines throughout Tidewater's service area. Tidewater has drawn down $1.8 million as of March 31, 2026 and expects that the requisitions will continue through 2026.

In May 2024, Tidewater closed on four Delaware SRF loans totaling $5.6 million, all at interest rates of 2.0% with maturity dates in 2044. These loans are for the construction, relocation, improvement, and/or interconnection of transmission mains

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

and construction of a water treatment facility. In December 2025, Tidewater closed on an additional $1.0 million, 2.0% SRF loan with a maturity date of 2045 related to these projects. Tidewater has drawn down $2.1 million on these loans as of March 31, 2026. Each project has its own construction timetable with the last spending set to occur in 2027.

In December 2025, Southern Shores closed on a $0.4 million Delaware SRF loan with a 0.0% interest rate with a maturity date in 2045. This loan is for costs associated with Southern Shore's obligation, as required by federal law and Delaware regulations, to identify and inventory lead service lines in its service area. Southern Shores has drawn down $0.2 million on these loans as of March 31, 2026 and does not anticipate any further draws.

In February 2026, Pinelands Water and Pinelands Wastewater repaid in full $3.7 million and $3.4 million, respectively, of their amortizing secured notes. The interest rates and due dates on both of these notes were 6.17% and 2043, respectively.

In April 2026, Tidewater filed a petition with the DEPSC seeking approval to issue up to $25 million of long-term debt through CoBank, ACB. Proceeds will be used to reduce Tidewater's Notes Payable and finance Tidewater's on-going capital program.

In order to fully fund the ongoing investment program in our utility plant infrastructure and maintain a balanced capital structure consistent with regulators' expectations for a regulated water utility, Middlesex may offer for sale additional shares of its common stock. The amount, timing and method of sale of common stock is dependent on the timing of construction expenditures, the level of additional debt financing and financial market conditions.

The NJBPU has approved Middlesex's petition to issue and sell up to 2.5 million shares of its common stock during the period January 2026 through December 2028, in one or more offerings through a traditional underwritten public offering and/or an ATM offering.

In May 2025, Middlesex entered into an ATM Equity Offering Sales Agreement (Equity Sales Agreement) with BofA Securities, Inc., Robert W. Baird & Co. Incorporated, and Janney Montgomery Scott (Janney), pursuant to which Middlesex may offer and sell shares of its common stock, no par value per share, from time to time in "at-the-market" offerings, having an aggregate gross sales price of up to $110.0 million. As of February 20, 2026, the Equity Sales Agreement was amended, replacing Janney with Huntington Securities, Inc. as a sales agent. The Company intends to use the net proceeds from these sales, after deducting commissions and offering expenses, to fund our capital expenditures, to purchase and maintain plant equipment, as well as for other general corporate purposes. For the three months ended March 31, 2026, Middlesex issued and sold a total of 49,305 shares of common stock, at a weighted average price of $54.82 per share, and received $2.7 million in net proceeds, under the Equity Sales Agreement. As of March 31, 2026, the Company has $77.3 million of aggregate gross sales remaining under the Equity Sales Agreement.

**Recent Accounting Pronouncements** – See Note 1 of the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of recent accounting pronouncements and guidance.

**Item 3. Quantitative and Qualitative Disclosures of Market Risk**

We are exposed to market risk associated with changes in interest rates and commodity prices. The Company is subject to the risk of fluctuating interest rates in the normal course of business. Our policy is to manage interest rates through the use of fixed rate long-term debt and, to a lesser extent, short-term debt. The Company's interest rate risk related to existing fixed rate, long-term debt is not material due to the term of the majority of our First Mortgage Bonds, which have final maturity dates ranging from 2026 to 2059. Over the next twelve months, approximately $7.7 million of existing long-term debt instruments will mature. Applying a hypothetical change in the rate of interest charged by 10% on those borrowings would not have a material effect on our earnings. Fixed rate long-term debt and variable rate short-term debt agreements were not entered into for trading purposes.

Our risks associated with commodity price increases for chemicals, electricity and other commodities are reduced through contractual arrangements and the ability to recover price increases through rates. Non-performance by these commodity suppliers could have a material adverse impact on our results of operations, financial position and cash flows.

We are exposed to credit risk for both our Regulated and Non-Regulated business segments. Our Regulated operations serve residential, commercial, industrial and municipal customers while our Non-Regulated operations engage in business activities with developers, government entities and other customers. Our primary credit risk is exposure to customer default on contractual obligations and the associated loss that may be incurred due to the non-payment of customer accounts receivable balances. Our credit risk is managed through established credit and collection policies which are in compliance

------

<u>[**Table of Contents**](#i74b0127d56964843b04734feec9656f2_7)</u>

with applicable regulatory requirements and involve monitoring of customer exposure and the use of credit risk mitigation measures such as letters of credit or prepayment arrangements. Our credit portfolio is diversified with no significant customer or industry concentrations. In addition, our Regulated businesses are generally able to recover all prudently incurred costs including uncollectible customer accounts receivable expenses and collection costs through customers' rates.

The Company's retirement benefit plan assets are exposed to the market prices variations of debt and equity securities. Changes to the Company's retirement benefit plan asset values can impact the Company's retirement benefit plan expense, funded status and future minimum funding requirements. Our exposure to market price risk in our retirement benefit plan assets is managed through our ability to recover retirement benefit plan costs through customer rates. There were no material changes to our primary market risk exposures or how such exposures are managed in 2026 nor are there expected to be in the future.

**Item 4. Controls and Procedures**

*Disclosure Controls and Procedures*

As required by Rule 13a-15 under the Securities and Exchange Act of 1934 (the Exchange Act), an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures was conducted by the Company's Chief Executive Officer along with the Company's Chief Financial Officer. Based upon that evaluation, the Company's Chief Executive Officer and the Company's Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective as of the end of the period covered by this Report. There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in Company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in Company reports filed under the Exchange Act is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding disclosure.
