Rockwell Medical, Inc. Reports Third Quarter 2018 Financial Results

WIXOM, Mich., Nov. 9, 2018 /PRNewswire/ — Rockwell Medical, Inc. (NASDAQ: RMTI) (the “Company”) today reported financial results for the third quarter ended September 30, 2018, and highlighted recent and upcoming corporate milestones.

Business Updates:

CMS Rule Clarifies U.S. Commercial Plans

IV Triferic Expected to be Eligible for TDAPA Pricing — Based on an analysis of CMS’ November 1, 2018 final rule regarding the new Transitional Drug Add On Pricing Adjustment (“TDAPA”) program, the Company believes that newly approved FDA therapies on or after January 1, 2020, are eligible for separate payment for a two year timeframe. Because the NDA filing for IV Triferic will be under a 505(b)1 pathway and therefore a new drug, the Company believes that, if approved by the FDA, this should allow for separate payment and a separate unique billing code. In accordance with the ruling, a separate TDAPA payment would last for two years following launch, after which IV Triferic would likely be priced inside the bundle. The Company is working with outside experts to optimize its NDA filing in 2019 and planning for a PDUFA action date and a U.S. launch of IV Triferic in the first half of 2020, subject to FDA approval.

Moving Ahead with U.S. Commercialization of Dialysate Triferic — Upon assessing the November 1, 2018 final payment rule from the Centers for Medicare & Medicaid Services (“CMS”), the Company has determined to move ahead with a commercial launch of its Dialysate formulation of Triferic, and is targeting a U.S. launch in the first half of 2019. Upon launch, the Company expects Dialysate Triferic to be bundled as part of the base rate to providers. Rockwell Medical is currently working to finalize its commercial plans and manufacturing scale-up, and is in the final stages of a market study to determine the optimal pricing and uptake of the 5 mL and powder packet versions of its Dialysate Triferic.

Closed Financing Transaction — On October 17, 2018, Rockwell Medical closed a financing transaction under which an affiliate of Richmond Brothers, Inc. invested a total of $22 million for 5,541,562 units in a private placement, with each unit consisting of one share of common stock and a five year warrant to purchase 50% of a share of common stock at $4.96 per share. With the proceeds from this offering, Rockwell Medical believes that it has sufficient capital to fund its business plan into 2020.

Assessing Commercial Potential for Calcitriol — Rockwell Medical is carefully examining Calcitriol’s potential to drive acceptable gross profits, and intends to share an update regarding its commercialization plans for this product in the first quarter of 2019.

Working to Best Position Concentrates Products — The Company is currently in discussions with potential partners to improve upon the economics of this line of products, and intends to share an update regarding its plans to enhance profitability in the first quarter of 2019.

Senior Leadership Appointments — Since Mr. Paul joined Rockwell Medical as President and CEO in early September, the Company appointed Jim McCarthy to the newly-formed role of Senior Vice President, Corporate and Business Development, and named Anne Boardman as Vice President of Strategic Accounts. Additionally, the Company appointed Angus Smith as Chief Financial Officer, effective at the end of November 2018. The Company expects to complete the hiring of its senior management team, as well as other key launch professional resources, in the fourth quarter of 2018.

Mr. Paul said, “Since joining Rockwell Medical as President and CEO in early September, one of my priorities has been undertaking a top-to-bottom review of the Company. It has become increasingly clear to me that Dialysate Triferic and IV Triferic present a fundamental opportunity to positively impact patients in the dialysis community and global anemia market, while simultaneously creating value for all our stakeholders. The management team and I have been preparing for the U.S. commercialization of Dialysate Triferic, and are working toward a U.S. launch in the first half of 2019. Given the sizable market opportunity, we are also

moving ahead with regulatory filings and the development of activities related to IV Triferic, which has significant potential to help patients both in the U.S. and abroad. If approved by the FDA, we are planning for a U.S. launch in the first half of 2020. In addition to Triferic-related activities, we are carefully studying the commercial opportunity for Calcitriol and are working to improve the overall economics in our Concentrates products given the profitability and strategic potential for this business line.”

Mr. Paul added, “As part of my review to better understand our products and our operations, I’ve spent time over the last 70 days getting to know the fantastic Rockwell Medical team. Together with our newly appointed senior leaders, I am energized by the opportunities ahead as we work to realize the full potential of the Company’s valuable assets, improve patient outcomes and create shareholder value.”
