Middlesex Water Company (MSEX) Q3 2026 earnings review
Middlesex Water profit jumps 29%, but new shares slow per-share gains
Middlesex Water, a regulated water utility in New Jersey and Delaware, turned higher customer rates and summer water usage into wider profit margins. Revenue rose 11% from a year ago to $60 million, while operating profit climbed 26% because day-to-day running costs grew less than 5%. Chief executive Nadine Leslie kept the $126 million full-year construction plan in place, which by our math leaves $42 million of spending for the fourth quarter.
| Operating revenue | $60.2M +11.3% from a year ago |
|---|---|
| Profit per share | $0.95 +23.4% from a year ago |
| 9-month infrastructure investment | $84M 67% of the ~$126M full-year plan |
| Full-year capital investment plan | Unchanged ~$126M (+31% from 2025) |
⚖️ Verdict: 🟢 Bullish
The story got better because the utility accelerated pipe and plant construction to $31 million this quarter and filed its first $2.5 million of semi-annual rate surcharges in New Jersey. One caution: issuing new stock to fund that construction pushed the diluted share count up almost 5%, keeping per-share profit growth 6 percentage points behind net income growth.
The question now is how much of the $506 million three-year construction plan will turn into per-share profit after regulatory lag and share dilution. Either surcharge approvals and future rate cases cover the $255 million treatment plant upgrade, or steady stock sales dilute shareholders before regulators grant full recovery. New Jersey regulators' decision on the September surcharge filings and the third-quarter filing's share-sale disclosures will give the next reading.
🐂 Bull Case
New Rates and Slower Costs Lifted Operating Margin
Middlesex Water supplies regulated water and wastewater services in New Jersey and Delaware, and higher water rates from its February 2026 New Jersey settlement are now flowing through profit. Operating margin expanded by 4.3 percentage points from a year ago to 37.0%, the highest level in over a year, as revenue grew more than twice as fast as day-to-day operating costs.
- Operations and maintenance (day-to-day running costs): 41.3% of revenue, down 2.6 percentage points from a year ago
- Depreciation (wear and tear on pipes and plants): 11.4% of revenue, down 1.4 percentage points
- Middlesex System revenue in New Jersey: up $4.7 million from a year ago
- Tidewater System revenue in Delaware: up $1.2 million from a year ago
Cost growth slowed because operations and maintenance rose 4.8% from a year ago, down from 10.1% in the second quarter. Unlike the nine-month summary, the company did not cite bad-debt provisions as a third-quarter cost driver. Depreciation also fell $0.1 million after the "implementation of depreciation rates from the study approved by the New Jersey Board of Public Utilities".
What to watch: the exact allowance for unpaid customer bills in the quarterly filing. A flat or smaller provision would confirm that customer payment issues from the first half have stabilized.
First Surcharge Filings Test Quick Rate Recovery
As a regulated utility, Middlesex must spend cash on pipes and treatment plants before it can ask regulators to raise customer bills. To shorten that wait, New Jersey regulators approved two surcharge programs in February 2026: the Distribution System Improvement Charge (DSIC, for pipe replacements) and the Resiliency and Environmental System Improvement Charge (RESIC, for reliability and treatment upgrades).
In September 2026, the utility filed its first petitions under that new cycle, requesting $1.7 million in annual DSIC revenue and $0.8 million in annual RESIC revenue. Meanwhile, construction accelerated: the group invested $84 million over the first nine months to "upgrade, replace and enhance the resiliency of its water and wastewater utility infrastructure". By our math, that means it spent $31 million in the third quarter, up from $21 million in the first quarter.
What to watch: New Jersey regulatory approval of the $2.5 million combined surcharge request in the fourth quarter. Full approval on schedule would show the utility can recover capital between major rate cases.
🐻 Bear Case
Issuing New Shares Slows Per-Share Profit Growth
Middlesex funds part of its $506 million three-year construction plan by selling new common stock to keep its balance sheet near the 54.25% equity ratio approved by New Jersey regulators. That steady issuing spreads profit across more shares, so per-share earnings grow more slowly than total company profit.
Diluted share count reached 19.03 million in the third quarter, up 4.8% from a year ago and up 289,000 shares from the second quarter by our math. That represents a faster pace of dilution than the 4.1% year-on-year increase in the second quarter. Because of those extra shares, diluted profit per share rose 23.4% to $0.95 while net income available to common shareholders climbed 29.2% to $18.0 million.
What to watch: remaining capacity under the at-the-market share sales program in the third-quarter filing. A drop below $60 million from $65.8 million in June would show management continued issuing stock at the second-quarter pace.
Summer Water Demand Pushed Revenue Above Rate Math
"Our strong third-quarter results reflect increased wholesale demand, higher customer consumption, and the continued execution of our regulatory strategy," chief executive Nadine Leslie said. While the February 2026 New Jersey base-rate increase provides a lasting step-up, the utility also benefited from comparing against a weak 2025 summer when wet weather depressed water usage.
Operating revenue rose 11.3% (or $6.1 million) to $60.2 million, even after the July 2025 Delaware rate increase passed its one-year anniversary. By our math, the New Jersey base-rate settlement adds about $3.6 million per quarter, or roughly 6% to 7% growth on last year's third-quarter base. The remaining $2.5 million of revenue growth came from customer consumption, wholesale volumes to other towns, and $0.2 million of "higher supplemental contract services", which can reverse when weather normalizes.
What to watch: wholesale revenue in the quarterly filing's segment table. If wholesale sales stayed near the 46% growth rate seen in the second quarter, fourth-quarter revenue growth will drop closer to the 6% rate baseline during winter.
Risks this quarter didn't answer
Four standing financial and regulatory concerns received no new figures in the third-quarter earnings release because the company reports balance-sheet, cash-flow, and project details only in its quarterly filing.
- Treatment plant cost jump: no breakdown explaining why the Carl J. Olsen plant upgrade for forever chemicals (PFAS) rose from $105 million to $255 million; the quarterly filing's capital outlook section is the next check.
- Next general rate case timing: no date for the base-rate filing needed to recover the $255 million treatment upgrade beyond surcharge caps.
- Operating cash flow conversion: no cash flow statement in the release to check whether nine-month operating cash flow rebounded after falling $4.0 million in the first half.
- Federal compliance timeline: no update on whether federal rules for forever chemicals will stay at April 2029 or move to 2031.

Dividend Raised for 54th Year Alongside Tiny Buy
Middlesex raised its quarterly cash dividend by 5.56% to $0.38 per share ($1.52 annually), marking its 54th straight year of dividend increases after a 5.88% raise last year. Separately, Delaware regulators approved its Tidewater subsidiary's purchase of Mount Pleasant MHP's water assets for $25,000, adding 39 customers in New Castle County.
💲 Other KPIs
Nearly doubled from $0.43 million a year ago, and up from $0.70 million in the second quarter. Allowance for funds used during construction — an accounting credit for the cost of financing projects before they enter service — rose 80.1% over the first nine months to $2.19 million as pipe and plant spending grew, lifting net income.
Unchanged from $4.20 million a year ago, slowing from a 10.8% year-on-year increase in the second quarter and an 18.5% rise in the first quarter. For the first nine months, interest charges rose 8.5% to $11.43 million, so steady third-quarter borrowing costs helped more of the operating profit gain reach the bottom line.
🔮 Guidance
Unchanged. The utility still plans to invest about $126 million in water and wastewater infrastructure this year, up 31.3% from $96 million in 2025. With $84 million (67%) spent in the first nine months, by our math the plan leaves $42 million for the fourth quarter — up from $31 million in Q3 and 75% above last year's Q4.
❓ Key Questions
How much new stock did Middlesex sell in Q3?
Diluted shares rose by 289,000 from the second quarter. The quarterly filing's capitalization note will show how much of the $65.8 million at-the-market share issuance program remains and at what average price the utility sold shares.
How much of Q3 revenue growth came from wholesale water?
Middlesex System revenue rose $4.7 million, above the roughly $3.6 million quarterly lift from the February base-rate increase. The segment footnote will show whether wholesale demand kept growing near the second quarter's 46% pace.
Did customer bad-debt provisions ease in the third quarter?
Management cited higher credit-loss reserves as a cost driver for the nine-month period but omitted it from the third-quarter explanation. Quantifying the reserve change will show if customer bill collection has stabilized.
Why did the Carl J. Olsen plant budget more than double?
The planned forever-chemicals upgrade at the Carl J. Olsen plant jumped from $105 million in the 2025–2027 plan to $255 million in the 2026–2028 plan without an explanation of how much is broader scope versus cost inflation.
