Nephros Announces Strong Financial Results for Quarter Ended June 30, 2026

Record Second-Quarter Net Revenue Growth of 36% to $6 million;
Core Programmatic Revenue Grew by 27% Year Over Year

SOUTH ORANGE, NJ, August 6, 2026 – Nephros, Inc. (Nasdaq: NEPH), a leading water technology company providing filtration solutions to the medical and commercial markets, today announced financial results for the second quarter ended June 30, 2026.

Financial Highlights

“The second quarter of 2026 marks another significant milestone for Nephros, as we delivered the highest quarterly revenue in the Company’s history,” said Robert Banks, President and Chief Executive Officer of Nephros. “Our results reflect broad-based strength across the business, driven by continued expansion of our core programmatic revenue, accelerating service revenue, growing adoption of our newer product offerings, and disciplined execution throughout the organization.”

Banks continued, “Perhaps most encouraging is the quality of our growth. Core programmatic revenue increased 27% over the prior year quarter. Programmatic revenue represents the foundation of our business, providing recurring replacement demand, long-term customer relationships, and increasing visibility into future revenue. We also achieved substantial growth in our service offerings, which nearly tripled compared to the prior year, which we believe reflects growing customer demand for installation, replacement, and water management support. Recent product launches addressing microplastics, nanoplastics, PFAS, sterile processing, drinking fountains, and bottle fillers continue to generate encouraging customer interest while expanding our addressable market.”

Commenting on the broader outlook, Banks said, “Beyond our financial performance, we continued to elevate the visibility of Nephros within the investment community. During the quarter we hosted our second Virtual Investor Event, participated in the Maxim Health, Wellness & Longevity Conference, announced our inclusion in the Russell Microcap Index, and continued expanding awareness of our differentiated technology through multiple industry-focused announcements. We believe increasing awareness among customers and investors alike is an important component of creating long-term shareholder value.”

Banks concluded, “As we enter the second half of 2026, we believe Nephros is stronger than at any point in our history. We have a growing recurring revenue base, expanding commercial opportunities, differentiated technology, an increasingly comprehensive service platform, and an exceptional team executing against a clear strategy. While we remain mindful of the broader economic environment, we believe the investments we have made over the past several years position us well to continue delivering sustainable growth and increasing shareholder value.”

Financial Performance for the Quarter Ended June 30, 2026

Net revenue for the three months ended June 30, 2026, and 2025 was $6.0 million and $4.4 million, respectively, an increase of 36%. This increase was driven primarily by increased product revenue from programmatic growth, which grew by 27% over the same period in 2025.

Cost of goods sold for the second quarter of 2026 was $2.0 million, compared with $1.6 million in the second quarter of 2025, an increase of 23%.

Gross margin for the second quarter of 2026 was 67%, compared with 63% in the second quarter of 2025. The increase of approximately 4 percentage points was primarily attributable to our recognition during the period of a refund of approximately $0.6 million for tariffs we previously paid under the International Emergency Economic Powers Act (IEEPA), which were declared invalid in February 2026. Following the Supreme Court’s decision and the establishment of the CBP refund process, we applied for and received approval of our tariff refund claim. We recorded the majority of the tariff refund as a reduction of cost of goods sold during the three months ended June 30, 2026. We have not yet received the refund and therefore have booked a receivable for that amount. The benefit to our gross margin resulting from the tariff refund was offset by increased costs due to the weakening of the U.S. dollar compared to the Euro, an increase in shipping expense and rapid growth in our service revenue, which yields lower gross margins than we realize from product sales.

Selling, general and administrative expenses for the second quarter of 2026 were approximately $2.4 million, compared with $2.2 million in 2025, an increase of 10% due to increases in headcount and an increase in sales commissions.

Research and development expenses for the second quarter of 2026 were approximately $366,000, compared with $311,000 in the second quarter of 2025, an increase of 18% due to higher salary expense.

Depreciation and amortization expenses for the second quarter of 2026 were approximately $29,000, compared with approximately $35,000 in the second quarter of 2025.

Net income for the second quarter of 2026 was $1.2 million, compared with $0.2 million during the same period in 2025.

Adjusted EBITDA for the second quarter 2026 was approximately $1.3 million, compared with approximately $0.4 million in the second quarter of 2025.

Financial Performance for the Six Months Ended June 30, 2026

Net revenue for the six months ended June 30, 2026, and 2025 was $11.2 million, and $9.3 million respectively, an increase of 21%. Our core programmatic revenue grew by 25% over the same period in 2025. The increase in programmatic sales reflects strong reorders, and a number of new active sites.

Cost of goods sold for the six months ended June 30, 2026 and 2025 was $4.2 million, and $3.3 million respectively, an increase of 26%. Gross margin for the six months ended June 30, 2026 was 63%, compared with 64% during the same period in 2025. The decrease of approximately one percentage point was primarily attributable to increased product costs due to the weakening of the U.S. dollar compared to the Euro, increased shipping expense and rapid revenue growth from our commercial products offerings and services revenue, both of which yield lower gross margins than our infection control business. However, our gross margins significantly benefited from our recognition during the 2026 period of the IEEPA tariff refund of approximately $0.6 million, which was recorded as a reduction of cost of goods sold during the six months ended June 30, 2026.

Selling, general and administrative expenses for the six months ended June 30, 2026 and 2025 were approximately $4.9 million, and $4.5 respectively, an increase of 11% primarily due to an increase in headcount and an increase in professional fees.

Research and development expenses for the six months ended June 30, 2026 and 2025 were $0.7 million and $0.6 million respectively.

Depreciation and amortization expenses for the six months ended June 30, 2026 and 2025 were approximately $58,000, and $74,000 respectively.

As a result of the improved sales and the approximately $0.6 million tariff refund net income for the six months ended June 30, 2026 was $1.3 million compared to $0.8 million during the same period in 2025.

Adjusted EBITDA for the six months ended June 30, 2026 was approximately $1.5 million, compared with approximately $1 million in the same period of 2025.

As of June 30, 2026, Nephros had cash and cash equivalents of approximately $4.7 million, compared to $5.4 million as of December 31, 2025, and remains debt free.

Adjusted EBITDA Definition and Reconciliation to GAAP Financial Measures

Adjusted EBITDA is calculated by taking net income calculated in accordance with generally accepted accounting principles (“GAAP”) and excluding all interest-related expenses and income, tax-related expenses and income, and non-cash items, including depreciation, amortization, non-cash inventory write-offs, and non-cash compensation. The following tables present a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, for the second quarter of the 2026 fiscal year:

Nephros believes that Adjusted EBITDA provides useful information to management and investors regarding certain financial and business trends relating to Nephros’ financial condition and results of operations. Management does not consider Adjusted EBITDA in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of Adjusted EBITDA is that it excludes significant expenses and income that are required by GAAP to be recognized in Nephros’ financial statements. In addition, Adjusted EBITDA is subject to inherent limitations as it reflects the exercise of judgments by management about which expenses and income are excluded or included in determining Adjusted EBITDA. To compensate for these limitations, management presents Adjusted EBITDA in connection with net income, the most directly comparable GAAP financial measure. Nephros urges investors to review the reconciliation of Adjusted EBITDA to net income and not to rely on any single financial measure to evaluate the business.
