Dear Friends and Shareholders,

This is an exciting time for Nephros. Demand for our products is increasing, revenue and growth rates are expanding, and we anticipate continued progress. At the same time, our stock price has been stagnant, which is difficult to reconcile with our recent operational trends and management’s optimism. In this public letter, we hope to address some of the questions we have heard from many of you over the past few months. We will begin with some history and context, and then describe our current strategies and plans for the future.

History and Context

Nephros was founded to make hemodiafiltration (HDF) broadly available to dialysis patients. After receiving FDA clearance for our HDF system in 2012, Nephros was not in a financial position to execute a full market launch, and instead opted to perform commercial pilot tests of the HDF system. During the same period, Nephros’ filtration product line was stagnant and sales were down. In early 2015, after three consecutive years of declining product sales, the Board of Directors took a hard look at the company’s strategy, and came to two conclusions: first, the time, expense and execution risk of commercializing the HDF system were difficult to justify for a small medical device company on a stand-alone basis; and second, the water filter business was not well positioned for growth. Without fundamental changes, the Board believed the future for Nephros was likely to be a continuing downward spiral of serial dilution, and destruction of shareholder value.

After a critical review of our markets, our customers, our products and our Company, management and the Board determined that we needed to make one major strategic shift and several operational changes to transform Nephros into a growth company. Strategically, we shifted our near-term focus from HDF to water filtration with prioritization of revenue growth and a disciplined minimization of expenses in order to achieve sustainable cash flow. Over the last two plus years, we have worked to broaden our water product portfolio and sales channels, and we have made operational changes to position the Company for success:

Early Results

As a result of the aforementioned actions and efforts, we believe that Nephros is now firmly in the upswing of the turnaround and in sight of our goal of sustainable cash flow positive operations. Tangible milestones include:

Short Term Outlook

The Nephros products on the market today have better filtration performance and longer service life than our competitors at competitive price points. Our products meet both the short-term needs of emergency remediation in the case of a legionella outbreak as well as the long-term needs for vigilant pathogen prevention in high-risk patient areas.

The remaining months of 2017 will include the following activities:

We are reiterating that we expect to achieve cash flow breakeven around the end of 2017, and we are targeting the first quarter of 2018 to be our first-ever quarter of sustainably positive cash flow. While the exact timing is dependent upon product rollouts and commercial uptake, we feel that we have positioned the Company well and have good visibility toward accomplishing the goal. We are hopeful that the valuation of the Company’s stock will begin to reflect the Company’s tangible milestones and improved outlook.

Longer Term Strategies

We have laid the groundwork for our next strategic shift: the expansion phase. As Nephros becomes cash flow positive, we expect to have the ability to more actively market our products into new water filtration markets outside the medical space. Additionally, we will have the flexibility to consider inorganic, accretive growth opportunities that leverage our current water filtration product sales channels.

Our HDF system remains an asset of Nephros, and we hope to soon re-ignite efforts to achieve the original vision of the Company as we explore opportunities to leverage available resources. We continue our efforts to learn more about the application of HDF through our collaboration with Vanderbilt. We have designed a next generation system that we believe will dramatically reduce machine cost and simplifies the procedure for use, while not compromising on the enhanced filtration experience felt by the patient. We believe that we can provide the same benefits observed with our current HDF system but in a way that better meets the operational and cost restraints of the US dialysis landscape.

We are committed to up-listing Nephros’ common stock to a national exchange such as the NASDAQ or NYSE. However, we would need additional capital to meet the minimum equity requirements for listing on either exchange. We will carefully evaluate and balance the timing of such actions.

Closing Thoughts

In summary, we believe that the Nephros story has been substantially de-risked, and that we are on the path to sustainable growth and profitability. Revenue growth is key, and we now have the people, products, and partners in place to meet the needs of our customers and expand our business.

We thank you for your on-going support and hope to be able to reward your patience with significantly increased shareholder value. Going forward, we intend to do a better job communicating our story to a broader audience. The management team has been buying stock in the open market on a regular basis, which reflects our belief and confidence in Nephros and our alignment with the Company’s shareholders.

All the best,

Daron and Andy
