Medicure Reports Financial Results for Quarter Ended March 31, 2018

WINNIPEG, May 23, 2018 /CNW/ - Medicure Inc. ("Medicure" or the "Company") (TSXV:MPH, OTC:MCUJF), a cardiovascular pharmaceutical company, today reported its results from operations for the quarter ended March 31, 2018.

Quarter Ended March 31, 2018 Highlights:

Recorded net revenue from the sale of AGGRASTAT^® (tirofiban hydrochloride) of $6.1 million during the quarter ended March 31, 2018 compared to $7.0 million for the quarter ended March 31, 2017;

Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA¹) for the quarter ended March 31, 2018 was $874,000 compared to adjusted EBITDA of $1.7 million for the quarter ended March 31, 2017; and

Net income for the quarter ended March 31, 2018 was $1.4 million compared to a net loss of $5.1 million for the quarter ended March 31, 2017.

$72.4 million in cash and short-term investments as at March 31, 2018.

Financial Results

Net revenues from AGGRASTAT^® for the three months ended March 31, 2018 were $6.1 million compared to $7.0 million for the three months ended March 31, 2017.

The Company continues to experience an increase in patient market share held by the product and an increase in the number of new hospital customers using AGGRASTAT^® leading to the highest hospital demand for AGGRASTAT^® in the Company's history. Although, there was an increase in use of AGGRASTAT^®, the lower net revenue was largely due to a stronger Canadian dollar compared to its US counterpart and increased competitive pricing of generic Integrilin.

Medicure continues to focus on expanding the customer base for AGGRASTAT^®. Along with this, the Company has begun to diversify revenues with the recent launch of ZYPITAMAG^TM (pitavastatin magnesium), its second cardiovascular drug targeting the US market. Additional drugs are expected to be launched in the next 12 to 15 months.

Adjusted EBITDA for the three months ended March 31, 2018 was $874,000 compared to $1.7 million for the three months ended March 31, 2017. The decrease in adjusted EBITDA for the quarter is the result of:

lower revenues which were primarily due to lower discounted prices for AGGRASTAT^® and a higher Canadian dollar relative to its US counterpart,

higher cost of goods sold due to higher volume of AGGRASTAT^® sold during the period,

partially offset by;

lower research and development expenses when compared to the same period in 2017 as a result of timing of expenses relating to the Company's research and development projects.

Net income for the three months ended March 31, 2018 was $1.4 million or $0.09 per share compared to a net loss of $5.1 million or $0.32 per share for the three months ended March 31, 2017, however the net loss for the 2017 quarter includes a net loss of $6.3 million from discontinued operations relating to the results from the Apicore business, which was divested in 2017. Excluding the loss from discontinued operations, net income for the three months ended March 31, 2018 increased by $176,000 over same period in 2017 primarily due to foreign exchange gains resulting from increased U.S. dollar denominated cash and short-term investment balances, partially offset by lower revenues for the three months ended March 31, 2018.

As at March 31, 2018, the Company had cash and short-term investments totaling $72.4 million compared to $5.3 million as of December 31, 2017. This consisted of $14.4 million of unrestricted cash and $58.0 million of short-term investments in the form of term deposits with maturities of greater than three months and less than one year. As at March 31, 2018, the Company had working capital of $73.6 million compared to December 31, 2017 of $70.9 million. The Company had cash from operating activities of $319,000 for the three months ended March 31, 2018 compared to cash used in operating activities of $834,000 for the three months ended March 31, 2017.

All amounts referenced herein are in Canadian dollars unless otherwise noted.

Notes

⁽¹⁾ The Company defines EBITDA as "earnings before interest, taxes, depreciation, amortization and other income or expense" and Adjusted EBITDA as "EBITDA adjusted for non-cash and one-time items". The terms "EBITDA" and "Adjusted EBITDA", as it relates to the quarters ended March 31, 2018 and 2017 results prepared using International Financial Reporting Standards ("IFRS"), do not have any standardized meaning according to IFRS. It is therefore unlikely to be comparable to similar measures presented by other companies.
