Nephros Announces Fourth Quarter and Fiscal Year 2022 Financial Results

Full-Year Net Revenue of $10 Million and Fourth Quarter Net Revenue of $2.6 Million

SOUTH ORANGE, NJ, March 8, 2023 – Nephros, Inc. (Nasdaq: NEPH), a leading water technology company providing filtration solutions to the medical and commercial markets, today announced financial results for the fourth quarter and fiscal year ended December 31, 2022.

Financial Highlights

Fourth Quarter Ended December 31, 2022 – Consolidated

Year-End 2022 – Consolidated

“2022 was a year of refocusing and rebuilding for Nephros,” said Andy Astor, President and Chief Executive Officer. “After a challenging first half of the year, we established a target of cash flow breakeven (“CFBE”) by mid-year 2023, coupled with significant revenue growth by that same time. We have made good progress on both fronts.”

“In our efforts to achieve CFBE, we took multiple actions, including broad headcount and expense reductions, the disposition of our Pathogen Detection Systems (“PDS”) business segment, and two price increases during the year, which were intended to return us to target gross margins of 55-60%. I am pleased to report that our fourth-quarter gross margins were 59%. Additionally, our net cash usage for the first half of the year was $2.8 million, compared to $0.5 million in the second half of the year, an 80% improvement.”

Mr. Astor continued, “In an effort to set the company up for future revenue growth, we took several actions, including a restructuring of our sales organization, the doubling of our sales team, and the relaunch of our commercial filtration business, which included a rebrand of our commercial filter products from Aether to Nephros. Of further note, we established a strategic partnership with Donastar Enterprises, LLC as the exclusive master distributor of our commercial filters in the food & beverage and hospitality markets.”

Nephros anticipates further cost reductions in the second quarter of this year, due to the planned cessation of operations by our majority-owned subsidiary, Specialty Renal Products, Inc. (“SRP”). In February 2023, SRP management unsuccessfully concluded its efforts to identify a strategic partner to support a commercial launch of SRP’s second-generation HDF product. SRP’s capital resources are nearly exhausted and it has been unable to procure additional financing. Accordingly, the SRP board of directors recently resolved, subject to approval of SRP’s stockholders, to wind down SRP’s operations and liquidate its remaining assets. Nephros expects to re-evaluate opportunities for HDF in the future but has no immediate plans to do so.

Consolidated Adjusted EBITDA Definition and Reconciliation to GAAP Financial Measures

Adjusted EBITDA loss from continuing operations is calculated by taking net loss from continuing operations calculated in accordance with generally accepted accounting principles (“GAAP”) and excluding all interest-related expenses and income, tax-related expenses and income, non-recurring expenses and income, and non-cash items, including depreciation, amortization and non-cash compensation. The following table presents a reconciliation of Adjusted EBITDA loss from continuing operations to net loss from continuing operations, the most directly comparable GAAP financial measure, for the fourth quarter of the 2022 and 2021 fiscal years:

Nephros believes that Adjusted EBITDA loss from continuing operations 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 loss from continuing operations in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of Adjusted EBITDA loss from continuing operations is that it excludes significant expenses and income that are required by GAAP to be recognized in Nephros’ consolidated financial statements. In addition, Adjusted EBITDA loss from continuing operations 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 loss from continuing operations. In order to compensate for these limitations, management presents Adjusted EBITDA loss from continuing operations in connection with net loss from continuing operations, the most directly comparable GAAP financial measure. Nephros urges investors to review the reconciliation of Adjusted EBITDA loss from continuing operations to net loss from continuing operations and not to rely on any single financial measure to evaluate the business.
