DOYLESTOWN, Pennsylvania – June 13, 2017. ProPhase Labs, Inc. (NASDAQ: PRPH, www.ProPhaseLabs.com) today reported that on June 12, 2017 it entered into a Stock Purchase Agreement with each of Mark S. Leventhal, a former director of the Company, and certain other persons and entities associated and/or affiliated with Mr. Leventhal (the “Leventhal Holders”), pursuant to which it purchased at the closing today all 1,061,980 shares of common stock of the Company then held by the Leventhal Holders, representing an approximate 6.2% aggregate ownership interest in the Company (based on 17,221,776 shares of common stock outstanding as of June 12, 2017). Upon consummation of the transactions, the Leventhal Holders ceased to hold any direct or indirect ownership interest in the Company. Additionally, the number of shares of common stock outstanding decreased from 17,221,776 to 16,159,796 as of June 13, 2017.

Pursuant to the terms of the Purchase Agreements, the total consideration paid by the Company to the Leventhal Holders for their shares was $1,858,465, which amount was equal to the product of (i) $1.75 multiplied by (ii) the number of shares purchased.

Mr. Karkus stated, “We continue to have significant overhead costs and responsibilities related to the transition of our Cold-EEZE^® Business, which we sold to a wholly-owned subsidiary of Mylan N.V. (“Mylan”) on March 29, 2017. Pursuant to our agreement with Mylan, we will continue to serve as the contract manufacturer of Cold-EEZE^® lozenges for Mylan. We hope to leverage our manufacturing business by creating new contract manufacturing and private label opportunities. We currently expect our manufacturing operations to operate at approximately breakeven for the remainder of this year.”

Mr. Karkus also noted, “We started shipping our new dietary supplement, Legendz XL^®, to a major retail drug chain during the first quarter of 2017. However, we will require significant growth in distribution and retail channels in order to achieve a successful launch and build a successful new product line.”

Additionally Mr. Karkus stated, “We anticipate incurring operating losses for the foreseeable future related to costs incurred for the Cold-EEZE^® Business transition to Mylan and expenses incurred in the development of our dietary supplement business. We are also actively exploring new product technologies, applications, product line extensions and other new product opportunities in the over the counter remedies market. We will also consider and pursue other alternatives and strategies, including, but not limited to, investments and acquisitions in other sectors and industries.”
