VolitionRx Announces Appointment of David Kratochvil as Chief Financial Officer

NAMUR, Belgium, August 17, 2015 - VolitionRx Limited (NYSE MKT: VNRX), a life sciences company focused on developing blood-based diagnostic tests for a broad range of cancer types and other conditions, today announced the appointment of David Kratochvil as its Chief Financial Officer and Treasurer, effective August 17, 2015. Kratochvil joins VolitionRx to lead the Company’s financial strategy in preparation for increased activity related to initial market entry of its NuQ^® tests in the U.S. and several markets worldwide. Kratochvil replaces Mike O’Connell, who has served as Chief Financial Officer and Treasurer on a consulting basis since July 2014 through Isosceles Finance Limited, an accounting services company he founded in 2001.

"David is an accomplished U.S.-based executive who brings a wealth of financial and capital markets expertise, and we are excited to have him join our team,” said Cameron Reynolds, President and Chief Executive Officer of VolitionRx. “We are approaching a number of key inflection points in the coming months and recognized the importance of enhancing our executive suite to effectively leverage the opportunities that lie ahead. David’s addition further strengthens the leadership within the organization, especially in the U.S., and we look forward to his contributions as we continue working toward several anticipated milestones. His very lengthy capital market experience, coupled with his strong financial background, were the key factors in his appointment to this critical role.”

Kratochvil brings more than 28 years of broad financial sector experience and leadership to his role at VolitionRx. He joins the Company from Euro Pacific Capital, where he served as Managing Director in the Corporate Finance department overseeing the firm’s investment banking efforts across a variety of sectors. At Euro Pacific since 2008, Kratochvil also served as Director of Research where he managed a team of equity analysts and increased research coverage.

Prior to Euro Pacific, Kratochvil had a lengthy career analyzing and investing in international securities. He was an international portfolio manager at Omega Advisors where he analyzed, executed and monitored investments across a variety of asset classes. Prior to joining Omega, he was a Director at Merrill Lynch Asset Management in London where he invested throughout emerging European markets. Additionally, Kratochvil founded his own advisory firm, Vista Capital Advisors, to provide global investment advice. He also worked as an equity analyst in New York, a private equity investor in Prague, and as a business tax consultant in New York.

Kratochvil earned a Master of Business Administration (MBA) in Finance and International Business from the University of Chicago’s Booth School of Business, and he holds a Bachelor of Science in Economics (BS Econ) with specialization in Finance and Accounting from University of Pennsylvania’s Wharton School.

“I am grateful to Cameron and the VolitionRx Board for the opportunity to join such a vibrant and motivated management team that has built VolitionRx from the ground up in the past five years,” said Kratochvil. “NuQ^® and the Company’s proprietary Nucleosomics^® technology platform have the potential to redefine the early detection of many types of cancer, make a significant impact on the industry and, most importantly, the lives of patients. I aim to give the Company a very strong focus on U.S. financial markets and assist in the business planning and financial modelling to launch the suite of NuQ^® products worldwide.”

O’Connell added, “I look forward to continuing my work with VolitionRx to ensure a smooth transition of the CFO role to David, and over the longer term, to providing Group Financial Controller services through Isosceles Finance. Given the progress that VolitionRx has made in recent years and anticipated future milestones, engaging a full-time CFO was an important next step in the Company’s evolution.”

About VolitionRx

VolitionRx is a life sciences company focused on developing diagnostic tests for cancer and other conditions. The tests are based on the science of Nucleosomics®, which is the practice of identifying and measuring nucleosomes in the bloodstream or other bodily fluid – an indication that disease is present.

VolitionRx’s goal is to make the tests as common and simple to use, for both patients and doctors, as existing diabetic and cholesterol blood tests. VolitionRx’s research and development activities are currently centered in Belgium as the company focuses on bringing its diagnostic products to market first in Europe, then in the US and ultimately, worldwide.
