Winter Springs, Florida, April 30, 2018 — IRADIMED CORPORATION (NASDAQ:IRMD), a leader in the development of innovative magnetic resonance imaging (“MRI”) medical devices and the only known provider of a non-magnetic intravenous (“IV”) infusion pump system that is designed to be safe for use during MRI procedures, today announced financial results for the three months ended March 31, 2018.

For the first quarter ended March 31, 2018, the Company reported revenue of $7.1 million compared to $5.2 million for the first quarter 2017. Net income was $0.8 million, or $0.07 per diluted share, compared to a net loss of $(0.2) million, or $(0.02) per share for the first quarter 2017. Gross profit margin was 76.2 percent, compared to 73.1 percent for the first quarter 2017. Domestic sales were 84.1 percent of total revenue, compared to 83.6 percent for the first quarter 2017. Revenue from sales of our patient vital signs monitor was $1.2 million for the first quarter 2018 compared to $0.4 million for the first quarter 2017.

Non-GAAP net income was $1.2 million for the quarter ended March 31, 2018, which excludes $0.3 million of stock compensation expense, net of tax. Non-GAAP net income for the quarter ended March 31, 2017 was $0.0 million. Non-GAAP earnings per diluted share was $0.10, compared to $0.00 for the first quarter 2017. Free cash flow was $1.5 million, compared to $(0.4) million for the first quarter 2017.

As of March 31, 2018, the Company had combined cash and investments of $27.9 million.

“I am very pleased with these results, which illustrate the strength of our business and the positive customer response toward our new patient monitor. Revenue for the first quarter increased nearly 38% over the first quarter last year and both GAAP and non-GAAP earnings were above our guidance. This is a solid first step for 2018 and a good start toward achieving our goal of $100 million in annual revenue in the next five years,” said Roger Susi, President and Chief Executive Officer of the Company.

Financial Guidance

For the second quarter 2018, the Company expects to report revenue of $7.2 million to $7.3 million, GAAP diluted earnings per share of $0.07 to $0.08 and non-GAAP diluted earnings per share of $0.10 to $0.11.

The Company increased its full year 2018 earnings guidance and now expects to report GAAP diluted earnings per share of $0.30 to $0.33 and non-GAAP diluted earnings per share of $0.40 to $0.43. The Company previously expected full year 2018 GAAP diluted earnings per share of $0.22 to $0.27 and non-GAAP diluted earnings per share of $0.33 to $0.38. Full year 2018 revenue guidance was unchanged at $29.3 million to $30.0 million.

The Company’s non-GAAP earnings per share guidance excludes stock-based compensation expense, net of tax, which the Company expects to be approximately $1.3 million and $0.3 million for the full year and second quarter 2018, respectively.

Use of non-GAAP Financial Measures

The Company believes the use of non-GAAP net income, free cash flow and infrequent income tax items are helpful to our investors. These measures, which we refer to as our non-GAAP financial measures, are not prepared in accordance with GAAP. We calculate non-GAAP net income as net income excluding stock-based compensation expense, net of tax. Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company’s non-cash expenses, we believe that providing non-GAAP financial measures that exclude stock-based compensation expense allows for meaningful comparisons between our operating results from period to period. We calculate free cash flow as net cash provided by operating activities less net cash used in investing activities for purchases of property and equipment. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by our business that can be used for strategic opportunities, including investing in our business, making strategic acquisitions, strengthening our balance sheet and returning cash to our shareholders via share repurchases. Infrequent tax items are considered based on their nature and are excluded from the provision for income taxes as these costs or benefits are not indicative of our normal or future provision for income taxes. All of our non-GAAP financial measures are important tools for financial and operational decision making and for evaluating our operating results.

A reconciliation of the non-GAAP financial measures used in this release to the most comparable U.S. GAAP measures for the respective periods can be found in the table later in this release immediately following the condensed statements of cash flows. These non-GAAP financial measures should not be considered in isolation or as a substitute for a measure of the Company’s operating performance or liquidity prepared in accordance with U.S. GAAP and are not indicative of net income or cash provided by operating activities.

About IRADIMED CORPORATION

IRADIMED CORPORATION is a leader in the development of innovative magnetic resonance imaging (“MRI”) compatible medical devices. We are the only known provider of a non-magnetic intravenous (“IV”) infusion pump system that is specifically designed to be safe for use during MRI procedures. We were the first to develop an infusion delivery system that largely eliminates many of the dangers and problems present during MRI procedures. Standard infusion pumps contain magnetic and electronic components which can create radio frequency interference and are dangerous to operate in the presence of the powerful magnet that drives an MRI system. Our patented MRidium® MRI compatible IV infusion pump system has been designed with a non-magnetic ultrasonic motor, uniquely-designed non-ferrous parts and other special features to safely and predictably deliver anesthesia and other IV fluids during various MRI procedures. Our pump solution provides a seamless approach that enables accurate, safe and dependable fluid delivery before, during and after an MRI scan, which is important to critically-ill patients who cannot be removed from their vital medications, and children and infants who must generally be sedated to remain immobile during an MRI scan.

Our 3880 MRI compatible patient vital signs monitoring system has been designed with non-magnetic components and other special features to safely and accurately monitor a patient’s vital signs during various MRI procedures. The IRADIMED 3880 system operates dependably in magnetic fields up to 30,000 gauss, which means it can operate virtually anywhere in the MRI scanner room. The IRADIMED 3880 has a compact, lightweight design allowing it to travel with the patient from their critical care unit, to the MRI and back, resulting in increased patient safety through uninterrupted vital signs monitoring and decreasing the amount of time critically ill patients are away from critical care units. The features of the IRADIMED 3880 include: wireless ECG with dynamic gradient filtering; wireless SpO2 using Masimo® algorithms; non-magnetic respiratory CO2; non-invasive blood pressure; patient temperature, and; optional advanced multi-gas anesthetic agent unit featuring continuous Minimum Alveolar Concentration measurements. The IRADIMED 3880 MRI compatible patient vital signs monitoring system has an easy-to-use design and allows for the effective communication of patient vital signs information to clinicians.
