MERIT MEDICAL SYSTEMS, INC. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation. The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three months ended March 31, 2015 and 2014 are not audited. Our consolidated financial statements are prepared in accordance with the requirements for unaudited interim periods, and consequently, do not include all disclosures required to be made in conformity with accounting principles generally accepted in the United States of America. In the opinion of our management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of March 31, 2015 and our results of operations and cash flows for the three-month periods ended March 31, 2015 and 2014. The results of operations for the three-month period ended March 31, 2015 are not necessarily indicative of the results for a full-year period. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with the Securities and Exchange Commission (the "SEC").

2. Inventories. Inventories at March 31, 2015 and December 31, 2014, consisted of the following (in thousands):

	March 31, 2015		December 31, 2014
Finished goods	$	43,622	$	50,000
Work-in-process	12,666		7,680
Raw materials	31,968		34,093
Total	$	88,256	$	91,773

3. Stock-Based Compensation. Stock-based compensation expense before income tax expense for the three-month periods ended March 31, 2015 and 2014, consisted of the following (in thousands):

	2015		2014
Cost of goods sold	$	93	$	43
Research and development	27		16
Selling, general, and administrative	400		280
Stock-based compensation expense before taxes	$	520	$	339

As of March 31, 2015, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $6.7 million and is expected to be recognized over a weighted average period of 3.7 years.

During the three months ended March 31, 2015, we granted awards representing 446,800 shares of our common stock. We did not grant any stock-based awards during the three months ended March 31, 2014. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the options granted during the three months ended March 31, 2015, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31, 2015
Risk-free interest rate	1.53%
Expected option life	5.0
Expected dividend yield	—%
Expected price volatility	35.11%

For purposes of the foregoing analysis, the average risk-free interest rate is determined using the U.S. Treasury rate in effect as of the date of grant, based on the expected term of the stock option. The expected term of the stock options is determined using the historical exercise behavior of employees. The expected price volatility is determined using a weighted average of daily historical volatility of our stock price over the corresponding expected option life and implied volatility based on recent trends of the daily

7

historical volatility. Compensation expense is recognized on a straight-line basis over the service period, which corresponds to the related vesting period.

4. Earnings Per Common Share (EPS). The computation of weighted average shares outstanding and the basic and diluted earnings per common share for the following periods consisted of the following (in thousands, except per share amounts):

	Net Income		Shares	Per Share Amount
Period ended March 31, 2015:
Basic EPS	$	5,174	43,703	$	0.12
Effect of dilutive stock options and warrants			442
Diluted EPS	$	5,174	44,145	$	0.12
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive			383
Period ended March 31, 2014:
Basic EPS	$	2,823	42,865	$	0.07
Effect of dilutive stock options and warrants			369
Diluted EPS	$	2,823	43,234	$	0.07
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive			362

5. Acquisitions. On January 6, 2015, we amended a distribution and patent sublicense agreement with Catheter Connections, Inc. ("CathConn"), a Utah corporation, which we had originally entered into on August 21, 2012 for CathConn's MaleCap Solo technology. The amendment provides exclusive rights for other aspects of CathConn's DualCap disinfecting cap technology. We paid CathConn an additional $250,000 in January 2015. The purchase price was allocated to a distribution agreement for $250,000, which we intend to amortize over 10 years.

On August 8, 2014, we entered into a license agreement and a distribution agreement with a medical device company for the right to manufacture and sell certain percutaneous transluminal angioplasty balloon catheter products. As of December 31, 2014, we had paid $3.0 million and recorded an additional $1.0 million obligation to accrued liabilities in connection with these two agreements. During the quarter ended March 31, 2015, we paid the $1.0 million that was accrued as of December 31, 2014. We are obligated to pay an additional $3.0 million to the licensor if certain milestones set forth in the license agreement are reached. We accounted for the transaction as an asset purchase. Of the purchase price paid as of March 31, 2015, $200,000 was allocated to a distribution agreement asset, which we are amortizing over a period of 3 years, and $3.8 million was allocated to a license agreement asset, which we intend to amortize over a period of 12 years.

6. Segment Reporting. We report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of cardiology and radiology medical device products which assist in diagnosing and treating coronary artery disease, peripheral vascular disease and other non-vascular diseases and includes embolization devices and CRM/EP devices. Our endoscopy segment consists of gastroenterology and pulmonology medical device products which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors. We evaluate the performance of our operating segments based on operating income (loss). Financial information relating to our reportable operating segments and reconciliations to the consolidated totals for the three-month periods ended March 31, 2015 and 2014, are as follows (in thousands):

Operating income
Cardiovascular	8,069		6,396
Endoscopy	635		93
Total operating income	8,704		6,489

7. Recent Accounting Pronouncements. In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. The adoption of this standard is not expected to have a material impact on our financial statements.

In August 2014, the FASB issued ASU 2014-15, which requires management to assess, at each annual and interim reporting period, the entity's ability to continue as a going concern within one year after the date that the financial statements are issued and provide related disclosures. The guidance is effective for the year ending December 31, 2016, with early adoption permitted. We have assessed the anticipated impact of this standard on our consolidated financial statements and disclosures and do not believe that it will have a material impact upon adoption.

In May 2014, the FASB issued authoritative guidance amending the FASB Accounting Standards Codification and creating a new Topic 606, Revenue from Contracts with Customers. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP applicable to revenue transactions. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The existing industry guidance will be eliminated when the new guidance becomes effective and annual disclosures will be substantially revised. The standard is effective for the Company’s first quarter of 2017. Early adoption is not permitted. Implementation may be either through retrospective application to each period from the first quarter of 2015 or with a cumulative effect adjustment upon adoption in 2017. Additional disclosures will also be required under the new standard. In April 2015, the FASB issued a proposal that, if approved, would extend the required implementation date one year to the first quarter of 2018 but also would permit companies to adopt the standard at the original effective date of 2017. We are assessing the impact this new standard will have on our consolidated financial statements and disclosures.

8. Income Taxes. Our overall effective tax rate for the three months ended March 31, 2015 and 2014 was 30.7% and 27.4%, respectively, which resulted in a provision for income taxes of $2.3 million and $1.1 million, respectively. The increase in the effective income tax rate for the first quarter of 2015, when compared to the first quarter of 2014, was due primarily to the increased profit of our U.S. operations, which are generally taxed at a higher rate than our foreign operations.

9. Long-term Debt. We entered into an Amended and Restated Credit Agreement, dated December 19, 2012, with the lenders who are or may become party thereto (collectively, the "Lenders") and Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent for the Lenders, which was amended on October 4, 2013 by a First Amendment to the Amended and Restated Credit Agreement by and among Merit, certain subsidiaries of Merit, the Lenders and Wells Fargo as administrative agent for the Lenders (as amended, the "Credit Agreement"). Pursuant to the terms of the Credit Agreement, the Lenders have agreed to make revolving credit loans up to an aggregate amount of $215 million. The Lenders also made a term loan in the amount of $100 million, repayable in quarterly installments in the amounts provided in the Credit Agreement until the maturity date of December 19, 2017, at which time the term and revolving credit loans, together with accrued interest thereon, will be due and payable. In addition, certain mandatory prepayments are required to be made upon the occurrence of certain events described in the Credit Agreement. Wells Fargo has agreed, upon satisfaction of certain conditions, to make swingline loans from time to time through the maturity date in amounts equal to the difference between the amounts actually loaned by the Lenders and the aggregate revolving credit commitment. The Credit Agreement is collateralized by substantially all of our assets. At any time prior to the maturity date, we may repay any amounts owing under all revolving credit loans, term loans, and all swingline loans in whole or in part, subject to certain minimum thresholds, without premium or penalty, other than breakage costs.

9

The term loan and any revolving credit loans made under the Credit Agreement bear interest, at our election, at either (i) the base rate (described below) plus 0.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), (ii) the London Inter-Bank Offered Rate (“LIBOR”) Market Index Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), or (iii) the LIBOR Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, the term loan and revolving credit loans under the Credit Agreement bear interest, at our election, at either (x) the base rate plus 1.00%, (y) the LIBOR Market Index Rate, plus 2.00%, or (z) the LIBOR Rate plus 2.00%. Swingline loans bear interest at the LIBOR Market Index Rate plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, swingline loans bear interest at the LIBOR Market Index Rate plus 2.00%. Interest on each loan featuring the base rate or the LIBOR Market Index Rate is due and payable on the last business day of each calendar month; interest on each loan featuring the LIBOR Rate is due and payable on the last day of each interest period selected by us when selecting the LIBOR Rate as the benchmark for interest calculation. For purposes of the Credit Agreement, the base rate means the highest of (i) the prime rate (as announced by Wells Fargo), (ii) the federal funds rate plus 0.50%, and (iii) LIBOR for an interest period of one month plus 1.00%. Our obligations under the Credit Agreement and all loans made thereunder are fully secured by a security interest in our assets pursuant to a separate collateral agreement entered into in conjunction with the Credit Agreement.

The Credit Agreement contains covenants, representations and warranties and other terms customary for revolving credit loans of this nature. In this regard, the Credit Agreement requires us to not, among other things, (a) permit the Consolidated Total Leverage Ratio (as defined in the Credit Agreement) to be greater than 4.75 to 1 through the end of 2013, no more than 4.00 to 1 as of the fiscal quarter ending March 31, 2014, no more than 3.75 to 1 as of the fiscal quarter ending June 30, 2014, no more than 3.50 to 1 as of the fiscal quarter ending September 30, 2014, no more than 3.25 to 1 as of the fiscal quarter ending December 31, 2014, no more than 3.00 to 1 as of any fiscal quarter ending during 2015, no more than 2.75 to 1 as of any fiscal quarter ending during 2016, and no more than 2.50 to 1 as of any fiscal quarter ending thereafter; (b) for any period of four consecutive fiscal quarters, permit the ratio of Consolidated EBITDA (as defined in the Credit Agreement and subject to certain adjustments) to Consolidated Fixed Charges (as defined in the Credit Agreement) to be less than 1.75 to 1; (c) subject to certain adjustments, permit Consolidated Net Income (as defined in the Credit Agreement) for certain periods to be less than $0; or (d) subject to certain conditions and adjustments, permit the aggregate amount of all Facility Capital Expenditures (as defined in the Credit Agreement) in any fiscal year beginning in 2013 to exceed $30 million. Additionally, the Credit Agreement contains various negative covenants with which we must comply, including, but not limited to, limitations respecting: the incurrence of indebtedness, the creation of liens or pledges on our assets, mergers or similar combinations or liquidations, asset dispositions, the repurchase or redemption of equity interests or debt, the issuance of equity, the payment of dividends and certain distributions, the entry into related party transactions and other provisions customary in similar types of agreements. As of March 31, 2015, we were in compliance with all covenants set forth in the Credit Agreement.

We had originally entered into an unsecured credit agreement, dated September 30, 2010, with certain lenders who were or became party thereto and Wells Fargo, as administrative agent for the lenders. Pursuant to the terms of that credit agreement, the lenders agreed to make revolving credit loans up to an aggregate amount of $175 million. Wells Fargo also agreed to make swingline loans from time to time through the maturity date of September 10, 2015 in amounts equal to the difference between the amount actually loaned by the lenders and the aggregate credit agreement. The unsecured credit agreement was amended and restated as of December 19, 2012, as the Credit Agreement.

In summary, principal balances under our long-term debt as of March 31, 2015 and December 31, 2014, consisted of the following (in thousands):

	2015		2014
Term loan	$	72,656	$	82,500
Revolving credit loans	140,222		141,990
Total long-term debt	212,878		224,490
Less current portion	10,000		10,000
Long-term portion	$	202,878	$	214,490

Future minimum principal payments on our long-term debt as of March 31, 2015, are as follows (in thousands):

10

Years Ending	Future Minimum
December 31	Principal Payments
2015	$	7,500
2016	10,000
2017	195,378
Total future minimum principal payments	$	212,878

As of March 31, 2015, we had outstanding borrowings of approximately $212.9 million under the Credit Agreement, with available borrowings of approximately $31.2 million, based on the leverage ratio in the terms of the Credit Agreement. Our interest rate as of March 31, 2015 was a fixed rate of 2.98% on $138.8 million as a result of an interest rate swap (see Note 10), a variable floating rate of 2.18% on $74.0 million and a variable floating rate of 2.27% on approximately $62,000. Our interest rate as of December 31, 2014 was a fixed rate of 2.98% on $140.0 million as a result of an interest rate swap, variable floating rate of 2.17% on $84.3 million and a variable floating rate of 2.26% on approximately $174,000.

10. Derivatives.

Interest Rate Swap. On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). The interest rates under both the interest rate swap and the underlying debt reset, the swap is settled with the counterparty, and interest is paid, on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of the Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017.

At March 31, 2015, our interest rate swap qualified as a cash flow hedge. The fair value of our interest rate swap at March 31, 2015 was a liability of approximately $325,000, which was offset by approximately $126,000 in deferred taxes. The fair value of our interest rate swap at December 31, 2014 was an asset of approximately $573,000, which was offset by approximately $223,000 in deferred taxes.

During the three months ended March 31, 2015 and 2014, the amounts reclassified from accumulated other comprehensive income to earnings due to hedge effectiveness were included in interest expense in the accompanying consolidated statements of income and were not material.

Foreign Currency Forward Contracts. On February 27, 2015, we forecasted a net exposure for March 31, 2015 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 309,000 Euros and 257,000 GBPs. In order to partially offset such risks, on February 27, 2015, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 309,000 Euros and notional amount of 257,000 GBPs. 

We enter into similar transactions at various times during the year to partially offset exchange rate risks we bear throughout the year. These contracts are marked to market at the end of each month. The effect on our consolidated statements of income for the three months ended March 31, 2015 and 2014 of all forward contracts, and the fair value of our open positions at March 31, 2015, were not material.

11. Fair Value Measurements. Our financial assets and (liabilities) carried at fair value measured on a recurring basis as of March 31, 2015 and December 31, 2014, consisted of the following (in thousands):

11

Certain of our business combinations involve the potential for the payment of future contingent consideration, generally based on a percentage of future product sales or upon attaining specified future revenue milestones. The contingent consideration liability is re-measured at the estimated fair value at each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements. Changes in the fair value of our contingent consideration liability during the three months ended March 31, 2015 and 2014, consisted of the following (in thousands):

	Three Months Ended			Three Months Ended
	March 31,			March 31,
	2015			2014
Beginning balance	$	1,886		$	2,526
Fair value adjustments recorded to income during the period	122			11
Contingent payments made	(166		)	(24		)
Ending balance	$	1,842		$	2,513

The recurring Level 3 measurement of our contingent consideration liability includes the following significant unobservable inputs at March 31, 2015 (amount in thousands):

Contingent consideration liability	Fair value at March 31, 2015		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	1,697	Discounted cash flow	Discount rate	1% - 14%
				Probability of milestone payment	90%
				Projected year of payments	2015-2028
Other payments	$	145	Discounted cash flow	Discount rate	5%
				Probability of milestone payment	100%
				Projected year of payments	2015-2016

The contingent consideration liability is re-measured to fair value each reporting period using projected revenues, discount rates, probabilities of payment, and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected revenues are based on our most recent internal operational budgets and long-range strategic plans. Increases (decreases) in discount rates and the time to payment may result in lower (higher) fair value measurements. A decrease in the probability of any milestone payment may result in lower fair value measurements. An increase (decrease) in either the discount rate or the time to payment, in isolation, may result in a significantly lower (higher) fair value measurement.

12

Our determination of the fair value of the contingent consideration liability could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We intend to record any such change in fair value to operating expenses in our consolidated statements of income. As of March 31, 2015, approximately $740,000 was included in other long-term obligations and $1.1 million was included in accrued expenses in our consolidated balance sheet. As of December 31, 2014, approximately $803,000 was included in other long-term obligations and $1.1 million was included in accrued expenses in our consolidated balance sheet. The cash paid to settle the contingent consideration liability recognized at fair value as of the acquisition date (including measurement-period adjustments) has been reflected as a cash outflow from financing activities in the accompanying consolidated statements of cash flows.

During the three-month periods ended March 31, 2015 and 2014, we had losses of approximately $14,000 and $34,000, respectively, related to the measurement of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition. 

The carrying amount of cash and cash equivalents, receivables, and trade payables approximates fair value because of the immediate, short-term maturity of these financial instruments. The carrying amount of long-term debt approximates fair value, as determined by borrowing rates estimated to be available to us for debt with similar terms and conditions. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents (Level 1).

12. Goodwill and Intangible Assets. The changes in the carrying amount of goodwill for the three months ended March 31, 2015 are as follows (in thousands):

	2015
Goodwill balance at January 1	184,464
Effect of foreign exchange	(59		)
Goodwill balance at March 31	$	184,405

There were no changes in the carrying amount of goodwill for the three months ended March 31, 2014.

As of March 31, 2015, we had recorded $8.3 million of accumulated goodwill impairment charges. All of the goodwill balance as of March 31, 2015 and December 31, 2014 related to our cardiovascular segment.

Other intangible assets at March 31, 2015 and December 31, 2014, consisted of the following (in thousands):

13. Commitments and Contingencies. In the ordinary course of business, we are involved in various claims and litigation matters. These claims and litigation matters may include actions involving product liability, intellectual property, contractual, and employment matters. We do not believe that any such actions are likely to be, individually or in the aggregate, material to our business, financial condition, results of operations or liquidity. However, in the event of unexpected further developments, it is possible that the ultimate resolution of these matters, or other similar matters, if unfavorable, may be materially adverse to our business, financial condition, results of operations or liquidity. Legal costs for these matters such as outside counsel fees and expenses are charged to expense in the period incurred.

OVERVIEW

The following discussion and analysis of our financial condition and results of operation should be read in conjunction with the consolidated financial statements and related condensed notes thereto, which are included in Part I of this Report.

We design, develop, manufacture and market single-use medical products for interventional and diagnostic procedures. For financial reporting purposes, we report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of cardiology and radiology devices, which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases, and includes our embolotherapeutic products. Our endoscopy segment consists of gastroenterology and pulmonology devices which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors.

For the three-month period ended March 31, 2015, we reported sales of approximately $129.6 million, up approximately $10.3 million, or 8.7%, from the three months ended March 31, 2014 of $119.2 million.

Gross profit as a percentage of sales decreased to 42.7% for the first quarter of 2015, compared to 43.6% for the first quarter of 2014. The decrease in gross margin for the first quarter of 2015 compared to the first quarter of 2014 was primarily related to higher average fixed overhead unit costs resulting from lower production volumes and sales discounts provided to various distributors in an effort to mitigate the effects of the devaluation of foreign currencies against the U.S. Dollar, both of which were partially offset by a favorable decline in our manufacturing operating costs and raw materials denominated in Euros as the U.S. Dollar strengthened against the Euro during the first quarter of 2015 compared to the same period of 2014.

Net income for the three months ended March 31, 2015 was approximately $5.2 million, or $0.12 per share, as compared to $2.8 million, or $0.07 per share, for the three months ended March 31, 2014. The increase in net income was attributable primarily to increased sales, lower operating expenses as a percentage of sales and decreased interest expense, all of which was partially offset by lower gross profit as a percentage of sales.

We anticipate our new facility in Tijuana, Mexico will begin production during the third quarter of 2015. The first products that we expect to be moved to this facility are currently being produced by an independent third party contract manufacturer in Tijuana, Mexico. We have made arrangements with the contract manufacturer to hire approximately 150 of their employees who are currently manufacturing our products. We believe the employees to be hired will include production operators and supervisors, quality and engineering personnel. We believe this arrangement will help us maintain the quality and production volumes of the products that are currently being produced in Mexico and will aid in our ability to transfer additional product lines from our other existing production facilities. As we begin operation of our Tijuana, Mexico production facility in 2015, we anticipate approximately $1.5 to $2.5 million of operating expenses that will be treated as selling, general and administrative costs, as opposed to cost of

15

sales, during a transition period of approximately nine months. Over the next three years as we move additional product lines to our new Tijuana facility, from other existing production facilities, we expect to see our overall gross profit and earnings improve. We anticipate that much of the anticipated improvement in gross margins and earnings we have forecasted will not be achieved until we are efficiently utilizing the Tijuana facility to produce product. It is anticipated that this utilization could occur sometime between the end of 2016 and the beginning of 2017.

In April 2015, we began to move the production lines from our West Jordan, Utah manufacturing site to our other existing manufacturing facilities. We plan to move additional production lines from our West Jordan site to our Tijuana facility in the third or fourth quarter of 2015. We currently believe the West Jordan manufacturing site, which is currently under an operating lease, should be vacated by the end of 2015.

During the first quarter of 2015, we benefited from the strengthening of the U.S. Dollar against the Euro, as the result of our natural hedge. This natural hedge is the result of having more cost of sales and operating expenses (European manufacturing facilities, European distribution site and an EMEA direct and distributor sales efforts) denominated in Euros than our Euro-denominated sales. The improvement in the U.S. Dollar against the Euro decreased our Euro-denominated sales and cost of sales in the three-month periods ended March 31, 2015 and 2014 by approximately $2.4 million and $2.2 million, respectively. The overall effect on gross profits of the strengthening of the U.S. Dollar against the Euro for the first quarter of 2015 was an improvement of 0.62%. Our operating expenses for the first quarter of 2015 also benefited from the strengthening of the U.S. Dollar against the Euro with a decrease in expenses of approximately $1.7 million.

We reduced our long-term debt by approximately $11.6 million in the first quarter of 2015 to approximately $212.9 million. Our debt to Consolidated EBITDA (as defined in our Amended and Restated Credit Agreement, dated December 19, 2012, with the lenders who are or may become party thereto (collectively, the "Lenders") and Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent for the Lenders, which was amended on October 4, 2013 by a First Amendment to the Amended and Restated Credit Agreement by and among Merit, certain subsidiaries of Merit, the Lenders and Wells Fargo as administrative agent for the Lenders (as amended, the "Credit Agreement") and subject to certain adjustments) ratio decreased to 2.62 on March 31, 2015, down from 3.24 on September 30, 2014 and 2.86 on December 31, 2014.

RESULTS OF OPERATIONS

The following table sets forth certain operational data as a percentage of sales for the three-month periods ended March 31, 2015 and 2014, as indicated:

	Three Months Ended
	March 31,
	2015	2014
Net sales	100%	100%
Gross profit	42.7%	43.6%
Selling, general, and administrative expenses	28.5%	30.9%

Other (expense) - net	(1.0)%	(2.2)%
Income before income taxes	5.8%	3.3%
Net income	4.0%	2.4%

Sales. Sales for the three months ended March 31, 2015 increased by 8.7%, or approximately $10.3 million, compared to the corresponding period of 2014. Listed below are the sales by product category within each business segment for the three-month periods ended March 31, 2015 and 2014 (in thousands):

Endoscopy
Endoscopy devices	11.2%	4,813		4,329
Total	8.7%	$	129,577	$	119,236

Our cardiovascular sales increased approximately $9.9 million, or 8.6%, for the quarter ended March 31, 2015 on sales of approximately $124.8 million, compared to sales of $114.9 million for the corresponding period of 2014. This improvement was largely the result of increased sales of catheters (particularly our Prelude® introducer sheath product line, ProGuide™ dialysis catheter product line and guiding catheter product line) our custom kits and procedure trays, our stand-alone devices (particularly our diagnostic guide wire product line, tubing product line and hydrophilic guide wire product line), and our inflation devices.

Our endoscopy sales increased 11.2% for the quarter ended March 31, 2015, on sales of approximately $4.8 million, when compared to the corresponding period of 2014 of approximately $4.3 million, primarily related to an increase in sales of our AEROmini® fully covered tracheobronchial stent and EndoMAXX™ fully covered esophageal stent.

Gross Profit.Gross profit as a percentage of sales decreased to 42.7% for the first quarter of 2015, compared to 43.6% for the first quarter of 2014. The decrease in gross margin for the first quarter of 2015 compared to the first quarter of 2014 was primarily related to higher average fixed overhead unit costs resulting from lower production volumes and sales discounts provided to various distributors in an effort to mitigate the effects of the devaluation of foreign currencies against the U.S. Dollar, both of which were partially offset by a favorable decline in our manufacturing operating costs and raw materials denominated in Euros as the U.S. Dollar strengthened against the Euro during the first quarter of 2015 compared to the corresponding period of 2014.

Operating Expenses. Selling, general, and administrative expenses increased approximately $122,000 but decreased as a percentage of sales to 28.5% for the three months ended March 31, 2015, from 30.9% for the three months ended March 31, 2014. The decrease in SG&A expense as a percentage of sales was primarily related to increased sales as well as a $1.4 million decrease in our Euro-based SG&A expense, due primarily to the strengthening of the U.S. Dollar against the Euro during the first quarter of 2015 compared to the comparable period of 2014.

Research and Development Expenses. Research and development expenses were 7.5% of sales for the three months ended March 31, 2015, compared with 7.4% of sales for the three months ended March 31, 2014. This increase was largely the result of additional research and development personnel to support various new product developments.

Operating Income. The following table sets forth our operating income by business segment for the three-month periods ended March 31, 2015 and 2014 (in thousands):

17

	Three Months Ended
	March 31,
	2015		2014
Operating Income
Cardiovascular	$	8,069	$	6,396
Endoscopy	635		93
Total operating income	$	8,704	$	6,489

Cardiovascular Operating Income. During the first quarter of 2015, we reported income from operations of approximately $8.1 million from our cardiovascular business segment, compared to income from operations of approximately $6.4 million for the corresponding period of 2014. The increase in operating income was primarily the result of increased sales and lower selling, general, and administrative expenses as a percentage of sales, partially offset by lower margins.

Endoscopy Operating Income. During the first quarter of 2015, we reported income from operations of approximately $635,000 from our endoscopy business segment, compared to income from operations of approximately $93,000 for the corresponding period of 2014. The increase in operating income was primarily the result of higher sales and gross profits, as well as, lower selling, general, and administrative expenses as a percentage of sales.

Other Expense - Net. Other expense, net, for the first quarter of 2015 was approximately $1.2 million, compared to other expense, net, of approximately $2.6 million for the first quarter of 2014. The decrease in other expense was principally the result of decreased interest expense related to a lower average outstanding debt balance and a lower interest rate for the first quarter of 2015 compared to the first quarter of 2014.

Income Taxes. Our overall effective tax rate for the three months ended March 31, 2015 was 30.7% compared to 27.4% for the three months ended March 31, 2014. Our provision for income taxes for the three months ended March 31, 2015 totaled $2.3 million of expense, compared to $1.1 million of expense for the corresponding period of 2014. The increase in the effective income tax rate was due primarily to the increased profit of our U.S. operations, which are generally taxed at a higher rate than our foreign operations income.

Net Income. During the first quarter of 2015, we reported net income of $5.2 million, an increase of 83.3% from $2.8 million for the first quarter of 2014. The increase in net income was primarily affected by increased sales, lower operating expenses as a percentage of sales and lower interest expense, and was partially offset by lower gross margins and a higher effective income tax rate.

LIQUIDITY AND CAPITAL RESOURCES

Our working capital as of March 31, 2015 and December 31, 2014 was $116.2 million and $116.9 million respectively. The decrease in working capital as of March 31, 2015 was primarily the result of decreases in trade and other receivables and inventory balances, which were partially offset by a decrease in trade payables and an increase in cash. As of March 31, 2015, we had a current ratio of 2.62 to 1.

At March 31, 2015 and December 31, 2014, we had cash and cash equivalents of approximately $9.9 million and $7.4 million respectively, of which approximately $9.8 million and $6.6 million, respectively, were held by foreign subsidiaries. For each of our foreign subsidiaries, we make an assertion as to whether the earnings are intended to be repatriated to the United States or held by the foreign subsidiary for permanent reinvestment. The cash held by our foreign subsidiaries for permanent reinvestment is generally used to fund the operating activities of our foreign subsidiaries and for further investment in foreign operations. We have accrued a deferred tax liability on our consolidated financial statements for the portion of our foreign earnings that are available to be repatriated to the United States.

In addition, cash held by our subsidiary in China is subject to local laws and regulations that require government approval for the transfer of such funds to entities located outside of China. As of March 31, 2015 and December 31, 2014, we had cash and cash equivalents of approximately $7.6 million and $5.2 million, respectively, held by our subsidiary in China.

During the three months ended March 31, 2015, our inventory balances decreased by approximately $3.5 million, from $91.8 million at December 31, 2014 to $88.3 million at March 31, 2015. The trailing twelve-month inventory turns for the three-month period ended March 31, 2015 improved to 3.37, compared to 3.12 for the three-month period ended March 31, 2014.

Pursuant to the terms of the Credit Agreement, the Lenders have agreed to make revolving credit loans up to an aggregate amount of $215 million. The Lenders also made a term loan in the amount of $100 million, repayable in quarterly installments in the

18

amounts provided in the Credit Agreement until the maturity date of December 19, 2017, at which time the term and revolving credit loans, together with accrued interest thereon, will be due and payable. In addition, certain mandatory prepayments are required to be made upon the occurrence of certain events described in the Credit Agreement. Wells Fargo has agreed, upon satisfaction of certain conditions, to make swingline loans from time to time through the maturity date in amounts equal to the difference between the amounts actually loaned by the Lenders and the aggregate revolving credit commitment. The Credit Agreement is collateralized by substantially all of our assets. At any time prior to the maturity date, we may repay any amounts owing under all revolving credit loans, term loans, and all swingline loans in whole or in part, subject to certain minimum thresholds, without premium or penalty, other than breakage costs.

The term loan and any revolving credit loans made under the Credit Agreement bear interest, at our election, at either (i) the base rate (described below) plus 0.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), (ii) the London Inter-Bank Offered Rate (“LIBOR”) Market Index Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), or (iii) the LIBOR Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, the term loan and revolving credit loans under the Credit Agreement bear interest, at our election, at either (x) the base rate plus 1.00%, (y) the LIBOR Market Index Rate, plus 2.00%, or (z) the LIBOR Rate plus 2.00%. Swingline loans bear interest at the LIBOR Market Index Rate plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, swingline loans bear interest at the LIBOR Market Index Rate plus 2.00%. Interest on each loan featuring the base rate or the LIBOR Market Index Rate is due and payable on the last business day of each calendar month; interest on each loan featuring the LIBOR Rate is due and payable on the last day of each interest period selected by us when selecting the LIBOR Rate as the benchmark for interest calculation. For purposes of the Credit Agreement, the base rate means the highest of (i) the prime rate (as announced by Wells Fargo), (ii) the federal funds rate plus 0.50%, and (iii) LIBOR for an interest period of one month plus 1.00%. Our obligations under the Credit Agreement and all loans made thereunder are fully secured by a security interest in our assets pursuant to a separate collateral agreement entered into in conjunction with the Credit Agreement.

The Credit Agreement contains customary covenants, representations and warranties and other terms customary for revolving credit loans of this nature. In this regard, the Credit Agreement requires us to not, among other things, (a) permit the Consolidated Total Leverage Ratio (as defined in the Credit Agreement) to be greater than 4.75 to 1 through the end of 2013, no more than 4.00 to 1 as of the fiscal quarter ending March 31, 2014, no more than 3.75 to 1 as of the fiscal quarter ending June 30, 2014, no more than 3.50 to 1 as of the fiscal quarter ending September 30, 2014, no more than 3.25 to 1 as of the fiscal quarter ending December 31, 2014, no more than 3.00 to 1 as of any fiscal quarter ending during 2015, no more than 2.75 to 1 as of any fiscal quarter ending during 2016, and no more than 2.50 to 1 as of any fiscal quarter ending thereafter; (b) for any period of four consecutive fiscal quarters, permit the ratio of Consolidated EBITDA (as defined in the Credit Agreement and subject to certain adjustments) to Consolidated Fixed Charges (as defined in the Credit Agreement) to be less than 1.75 to 1; (c) subject to certain adjustments, permit Consolidated Net Income (as defined in the Credit Agreement) for certain periods to be less than $0; or (d) subject to certain conditions and adjustments, permit the aggregate amount of all Facility Capital Expenditures (as defined in the Credit Agreement) in any fiscal year beginning in 2013 to exceed $30 million. Additionally, the Credit Agreement contains various negative covenants with which we must comply, including, but not limited to, limitations respecting: the incurrence of indebtedness, the creation of liens or pledges on our assets, mergers or similar combinations or liquidations, asset dispositions, the repurchase or redemption of equity interests or debt, the issuance of equity, the payment of dividends and certain distributions, the entry into related party transactions and other provisions customary in similar types of agreements. As of March 31, 2015, we were in compliance with all covenants set forth in the Credit Agreement.

As of March 31, 2015, we had available borrowings under the Credit Agreement of approximately $31.2 million. Our interest rate under the Credit Agreement as of March 31, 2015 was a fixed rate of 2.98% on $138.8 million as a result of an interest rate swap (see Note 10), a variable floating rate of 2.18% on $74.0 million and a variable floating rate of 2.27% on approximately $62,000. Our Total Leverage Ratio under the Credit Agreement for the quarter ended March 31, 2015, was 2.62 to 1. As a result of the quarterly adjustment of our Total Leverage Ratio, as contemplated by the Credit Agreement, the base interest rate on our term loan and amounts outstanding on our revolving credit loans is scheduled to drop 0.25% to 1.75%, from the current base rate of 2.00%, on May 25, 2015. The new base rate of 1.75% is scheduled to remain in effect until August 25, 2015, at which time the Credit Agreement provides for a new base rate to be determined.

Capital expenditures for property and equipment were approximately $9.5 million and $8.7 million, respectively, for the three-month periods ended March 31, 2015 and 2014, an increase of $0.8 million.

We currently believe that our existing cash balances, anticipated future cash flows from operations, borrowings under the Credit Agreement (approximately $31.2 million of borrowing availability as of March 31, 2015), and potential equipment financing will

19

be adequate to fund our current and currently planned future operations for the next twelve months and the foreseeable future. In the event we pursue and complete significant transactions or acquisitions in the future, additional funds will likely be required to meet our strategic needs, which may require us to raise additional funds in the debt or equity markets.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The SEC has requested that all registrants address their most critical accounting policies. The SEC has indicated that a “critical accounting policy” is one which is both important to the representation of the registrant’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. We base our estimates on past experience and on various other assumptions our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results will differ, and may differ materially from these estimates under different assumptions or conditions. Additionally, changes in accounting estimates could occur in the future from period to period. Our management has discussed the development and selection of our most critical financial estimates with the audit committee of our Board of Directors. The following paragraphs identify our most critical accounting policies:

Inventory Obsolescence. Our management reviews on a quarterly basis inventory quantities on hand for unmarketable and/or slow-moving products that may expire prior to being sold. This review includes quantities on hand for both raw materials and finished goods. Based on this review, we provide adjustments for any slow-moving finished good products or raw materials that we believe will expire prior to being sold or used to produce a finished good and any products that are unmarketable. This review of inventory quantities for unmarketable and/or slow moving products is based on forecasted product demand prior to expiration lives.

Forecasted unit demand is derived from our historical experience of product sales and production raw material usage. If market conditions become less favorable than those projected by our management, additional inventory write-downs may be required. During the years ended December 31, 2014, 2013 and 2012, we recorded obsolescence expense of approximately $2.3 million, $2.7 million, and $2.3 million, respectively, and wrote off approximately $2.4 million, $2.8 million, and $1.5 million, respectively. Based on this historical trend, we believe that our inventory balances as of March 31, 2015 have been accurately adjusted for any unmarketable and/or slow moving products that may expire prior to being sold.

Allowance for Doubtful Accounts. A majority of our receivables are with hospitals which, over our history, have demonstrated favorable collection rates. Therefore, we have experienced relatively minimal bad debts from hospital customers. In limited circumstances, we have written off bad debts as the result of the termination of our business relationships with foreign distributors. The most significant write-offs over our history have come from U.S. custom procedure tray manufacturers who bundle our products in surgical trays.

We maintain allowances for doubtful accounts relating to estimated losses resulting from the inability of our customers to make required payments. These allowances are based upon historical experience and a review of individual customer balances. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Stock-Based Compensation. We measure stock-based compensation cost at the grant date based on the value of the award and recognize the cost as an expense over the term of the vesting period. Judgment is required in estimating the fair value of share-based awards granted and their expected forfeiture rate. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.

Income Taxes. Under our accounting policies, we initially recognize a tax position in our financial statements when it becomes more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax positions that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authorities assuming full knowledge of the position and all relevant facts. Although we believe our provisions for unrecognized tax positions are reasonable, we can make no assurance that the final tax outcome of these matters will not be different from that which we have reflected in our income tax provisions and accruals. The tax law is subject to varied interpretations, and we have taken positions related to certain matters where the law is subject to interpretation. Such differences could have a material impact on our income tax provisions and operating results in the period(s) in which we make such determination.

Goodwill and Intangible Assets Impairment and Contingent Consideration. We test our goodwill balances for impairment as of July 1 of each year, or whenever impairment indicators arise. We utilize several reporting units in evaluating goodwill for

20

impairment. We assess the estimated fair value of reporting units based on discounted future cash flows. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment charge is recognized in an amount equal to the excess of the carrying amount of the reporting unit goodwill over implied fair value of that goodwill. This analysis requires significant judgment, including estimation of future cash flows and the length of time they will occur, which is based on internal forecasts, and a determination of a discount rate based on our weighted average cost of capital. During our annual test of goodwill balances in 2014, which was completed during the third quarter of 2014, we determined that the fair value of each reporting unit with goodwill exceeded the carrying amount.

We evaluate the recoverability of intangible assets whenever events or changes in circumstances indicate that an asset's carrying amount may not be recoverable. This analysis requires similar significant judgments as those discussed above regarding goodwill, except that undiscounted cash flows are compared to the carrying amount of intangible assets to determine if impairment exists. All of our intangible assets are subject to amortization.

Contingent consideration is an obligation by the buyer to transfer additional assets or equity interests to the former owner upon reaching certain performance targets. Certain of our business combinations involve the potential for the payment of future contingent consideration, generally based on a percentage of future product sales or upon attaining specified future revenue milestones. In connection with a business combination, any contingent consideration is recorded on the acquisition date based upon the consideration expected to be transferred in the future. We utilize a discounted cash flow method, which includes a probability factor for milestone payments, in valuing the contingent consideration liability. We re-measure the estimated liability each quarter and record changes in the estimated fair value through operating expense in our consolidated statements of income. Significant increases or decreases in our estimates could result in changes to the estimated fair value of our contingent consideration liability, as the result of changes in the timing and amount of revenue estimates, as well as changes in the discount rate or periods.

During the year ended December 31, 2014, we reduced the amount of the contingent consideration liability related to the Ostial PRO® Stent Positioning System, which we acquired in January 2012, by approximately $874,000. Under the terms of the Asset Purchase Agreement we executed with Ostial Solutions, LLC ("Ostial"), we are obligated to make contingent purchase price payments based on a percentage of future sales of products utilizing the Ostial PRO Stent Positioning System. The adjustment to the contingent consideration liability triggered a review of the intangible assets we acquired from Ostial, which resulted in an intangible asset write-down of approximately $1.1 million related to those assets. These adjustments reduced operating income for the year ended December 31, 2014 by approximately $228,000, or approximately $141,000 net of tax. The reduction of the Ostial contingent consideration liability and the impairment of the Ostial intangible assets was the result of our assessment that we are not likely to generate the level of revenues from sales of the Ostial PRO Stent Positioning System that we anticipated at the acquisition date.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our principal market risk relates to changes in the value of the Euro, the Chinese Yuan, and the Great British Pound ("GBP") relative to the value of the U.S. Dollar. We also have less significant market risks relating to the Hong Kong Dollar and the Swedish and Danish Kroner. Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. For the three-month period ended March 31, 2015, a portion of our revenues (approximately $27.1 million, representing approximately 20% of our aggregate revenues), was attributable to sales that were denominated in foreign currencies. All other international sales were denominated in U.S. Dollars. Certain of our expenses for the three-month period ended March 31, 2015 were also denominated in foreign currencies, which partially offset risks associated with fluctuations of exchange rates between foreign currencies and the U.S. Dollar. During the three-month period ended March 31, 2015, fluctuations in the exchange rate between foreign currencies and the U.S. Dollar resulted in a decrease in our gross revenues of approximately $2.2 million, or 1.7%, and an increase of 0.72% in gross profit, primarily as a result of a decrease in Irish manufacturing operating costs and raw materials denominated in Euros. Our Euro-denominated revenue represents our largest single currency risk. However, our Euro-denominated expenses associated with our European operations (manufacturing sites, a distribution facility and sales representatives) provide a natural hedge. Accordingly, changes in the Euro, and in particular a strengthening of the U.S. Dollar against the Euro, will generally have a positive effect our net income. We anticipate that a strengthening U.S. Dollar against the Euro of 10% would increase our net income by approximately $1.0 million Dollars. Conversely, a weakening U.S. Dollar against the Euro of 10% would have a negative impact on our net income of $1.0 million Dollars.

On February 27, 2015, we forecasted a net exposure for March 31, 2015 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 309,000 Euros and 257,000 GBPs. In order to partially offset such risks, on February 27, 2015, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 309,000 Euros and notional amount of 257,000 GBPs. We enter into similar transactions at various times during the year to partially offset exchange rate risks we bear throughout the year. These contracts are marked to market at the end of each month. The effect on our consolidated statements of income for the three months ended March 31, 2015 and 2014 of all forward contracts, and the fair value of our open positions as of March 31, 2015, were not material.

As discussed in Note 9 to our consolidated financial statements, as of March 31, 2015, we had outstanding borrowings of approximately $212.9 million under the Credit Agreement. Accordingly, our earnings and after-tax cash flow are affected by changes in interest rates. As part of our efforts to mitigate interest rate risk, on December 19, 2012, we entered into a LIBOR-based interest rate swap agreement having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. This instrument is intended to reduce our exposure to interest rate fluctuations and was not entered into for speculative purposes. Excluding the amount that is subject to a fixed rate under the interest rate swap and assuming the current level of borrowings remained the same, it is estimated that our interest expense and income before income taxes would change by approximately $741,000 annually for each one percentage point change in the average interest rate under these borrowings.

In the event of an adverse change in interest rates, our management would likely take actions to mitigate our exposure. However, due to the uncertainty of the actions that would be taken and their possible effects, additional analysis is not possible at this time. Further, such analysis would not consider the effects of the change in the level of overall economic activity that could exist in such an environment.

ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of March 31, 2015. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2015, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Interest Rate Swap. On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). The interest rates under both the interest rate swap and the underlying debt reset, the swap is settled with the counterparty, and interest is paid, on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of the Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017.

At March 31, 2015, our interest rate swap qualified as a cash flow hedge. The fair value of our interest rate swap at March 31, 2015 was a liability of approximately $325,000, which was offset by approximately $126,000 in deferred taxes. The fair value of our interest rate swap at December 31, 2014 was an asset of approximately $573,000, which was offset by approximately $223,000 in deferred taxes.

During the three months ended March 31, 2015 and 2014, the amounts reclassified from accumulated other comprehensive income to earnings due to hedge effectiveness were included in interest expense in the accompanying consolidated statements of income and were not material.

Foreign Currency Forward Contracts. On February 27, 2015, we forecasted a net exposure for March 31, 2015 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 309,000 Euros and 257,000 GBPs. In order to partially offset such risks, on February 27, 2015, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 309,000 Euros and notional amount of 257,000 GBPs. 

We enter into similar transactions at various times during the year to partially offset exchange rate risks we bear throughout the year. These contracts are marked to market at the end of each month. The effect on our consolidated statements of income for the three months ended March 31, 2015 and 2014 of all forward contracts, and the fair value of our open positions at March 31, 2015, were not material.

Fair Value Measurements

Our financial assets and (liabilities) carried at fair value measured on a recurring basis as of March 31, 2015 and December 31, 2014, consisted of the following (in thousands):

				Fair Value Measurements Using
	Total Fair			Quoted prices in		Significant other			Significant

Interest rate swap (1)	$	573		$	—	$	573		$	—

(1)    The fair value of the interest rate swap is determined based on forward yield curves.

Certain of our business combinations involve the potential for the payment of future contingent consideration, generally based on a percentage of future product sales or upon attaining specified future revenue milestones. The contingent consideration liability is re-measured at the estimated fair value at each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements. Changes in the fair value of our contingent consideration liability during the three months ended March 31, 2015 and 2014, consisted of the following (in thousands):

	Three Months Ended			Three Months Ended
	March 31,			March 31,
	2015			2014
Beginning balance	$	1,886		$	2,526
Fair value adjustments recorded to income during the period	122			11
Contingent payments made	(166		)	(24		)
Ending balance	$	1,842		$	2,513

The recurring Level 3 measurement of our contingent consideration liability includes the following significant unobservable inputs at March 31, 2015 (amount in thousands):

Contingent consideration liability	Fair value at March 31, 2015		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	1,697	Discounted cash flow	Discount rate	1% - 14%
				Probability of milestone payment	90%
				Projected year of payments	2015-2028
Other payments	$	145	Discounted cash flow	Discount rate	5%
				Probability of milestone payment	100%
				Projected year of payments	2015-2016

The contingent consideration liability is re-measured to fair value each reporting period using projected revenues, discount rates, probabilities of payment, and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected revenues are based on our most recent internal operational budgets and long-range strategic plans. Increases (decreases) in discount rates and the time to payment may result in lower (higher) fair value measurements. A decrease in the probability of any milestone payment may result in lower fair value measurements. An increase (decrease) in either the discount rate or the time to payment, in isolation, may result in a significantly lower (higher) fair value measurement.

Our determination of the fair value of the contingent consideration liability could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We intend to record any such change in fair value to operating expenses in our consolidated statements of income. As of March 31, 2015, approximately $740,000 was included in other long-term obligations and $1.1 million was included in accrued expenses in our consolidated balance sheet. As of December 31, 2014, approximately $803,000 was included in other long-term obligations and $1.1 million was included in accrued expenses in our consolidated balance sheet. The cash paid to settle the contingent consideration liability recognized at fair value as of the acquisition date (including measurement-period adjustments) has been reflected as a cash outflow from financing activities in the accompanying consolidated statements of cash flows.

During the three-month periods ended March 31, 2015 and 2014, we had losses of approximately $14,000 and $34,000, respectively, related to the measurement of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition. 

The carrying amount of cash and cash equivalents, receivables, and trade payables approximates fair value because of the immediate, short-term maturity of these financial instruments. The carrying amount of long-term debt approximates fair value, as determined by borrowing rates estimated to be available to us for debt with similar terms and conditions. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents (Level 1).

Acquisitions

Acquisitions. On January 6, 2015, we amended a distribution and patent sublicense agreement with Catheter Connections, Inc. ("CathConn"), a Utah corporation, which we had originally entered into on August 21, 2012 for CathConn's MaleCap Solo technology. The amendment provides exclusive rights for other aspects of CathConn's DualCap disinfecting cap technology. We paid CathConn an additional $250,000 in January 2015. The purchase price was allocated to a distribution agreement for $250,000, which we intend to amortize over 10 years.

On August 8, 2014, we entered into a license agreement and a distribution agreement with a medical device company for the right to manufacture and sell certain percutaneous transluminal angioplasty balloon catheter products. As of December 31, 2014, we had paid $3.0 million and recorded an additional $1.0 million obligation to accrued liabilities in connection with these two agreements. During the quarter ended March 31, 2015, we paid the $1.0 million that was accrued as of December 31, 2014. We are obligated to pay an additional $3.0 million to the licensor if certain milestones set forth in the license agreement are reached. We accounted for the transaction as an asset purchase. Of the purchase price paid as of March 31, 2015, $200,000 was allocated to a distribution agreement asset, which we are amortizing over a period of 3 years, and $3.8 million was allocated to a license agreement asset, which we intend to amortize over a period of 12 years.

Income Taxes. Our overall effective tax rate for the three months ended March 31, 2015 and 2014 was 30.7% and 27.4%, respectively, which resulted in a provision for income taxes of $2.3 million and $1.1 million, respectively. The increase in the effective income tax rate for the first quarter of 2015, when compared to the first quarter of 2014, was due primarily to the increased profit of our U.S. operations, which are generally taxed at a higher rate than our foreign operations.

Recent Accounting Pronouncements

Recent Accounting Pronouncements. In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. The adoption of this standard is not expected to have a material impact on our financial statements.

In August 2014, the FASB issued ASU 2014-15, which requires management to assess, at each annual and interim reporting period, the entity's ability to continue as a going concern within one year after the date that the financial statements are issued and provide related disclosures. The guidance is effective for the year ending December 31, 2016, with early adoption permitted. We have assessed the anticipated impact of this standard on our consolidated financial statements and disclosures and do not believe that it will have a material impact upon adoption.

In May 2014, the FASB issued authoritative guidance amending the FASB Accounting Standards Codification and creating a new Topic 606, Revenue from Contracts with Customers. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP applicable to revenue transactions. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The existing industry guidance will be eliminated when the new guidance becomes effective and annual disclosures will be substantially revised. The standard is effective for the Company’s first quarter of 2017. Early adoption is not permitted. Implementation may be either through retrospective application to each period from the first quarter of 2015 or with a cumulative effect adjustment upon adoption in 2017. Additional disclosures will also be required under the new standard. In April 2015, the FASB issued a proposal that, if approved, would extend the required implementation date one year to the first quarter of 2018 but also would permit companies to adopt the standard at the original effective date of 2017. We are assessing the impact this new standard will have on our consolidated financial statements and disclosures.

Debt Disclosure [Abstract]

Long-Term Debt

Long-term Debt. We entered into an Amended and Restated Credit Agreement, dated December 19, 2012, with the lenders who are or may become party thereto (collectively, the "Lenders") and Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent for the Lenders, which was amended on October 4, 2013 by a First Amendment to the Amended and Restated Credit Agreement by and among Merit, certain subsidiaries of Merit, the Lenders and Wells Fargo as administrative agent for the Lenders (as amended, the "Credit Agreement"). Pursuant to the terms of the Credit Agreement, the Lenders have agreed to make revolving credit loans up to an aggregate amount of $215 million. The Lenders also made a term loan in the amount of $100 million, repayable in quarterly installments in the amounts provided in the Credit Agreement until the maturity date of December 19, 2017, at which time the term and revolving credit loans, together with accrued interest thereon, will be due and payable. In addition, certain mandatory prepayments are required to be made upon the occurrence of certain events described in the Credit Agreement. Wells Fargo has agreed, upon satisfaction of certain conditions, to make swingline loans from time to time through the maturity date in amounts equal to the difference between the amounts actually loaned by the Lenders and the aggregate revolving credit commitment. The Credit Agreement is collateralized by substantially all of our assets. At any time prior to the maturity date, we may repay any amounts owing under all revolving credit loans, term loans, and all swingline loans in whole or in part, subject to certain minimum thresholds, without premium or penalty, other than breakage costs.

The term loan and any revolving credit loans made under the Credit Agreement bear interest, at our election, at either (i) the base rate (described below) plus 0.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), (ii) the London Inter-Bank Offered Rate (“LIBOR”) Market Index Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1), or (iii) the LIBOR Rate (as defined in the Credit Agreement) plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, the term loan and revolving credit loans under the Credit Agreement bear interest, at our election, at either (x) the base rate plus 1.00%, (y) the LIBOR Market Index Rate, plus 2.00%, or (z) the LIBOR Rate plus 2.00%. Swingline loans bear interest at the LIBOR Market Index Rate plus 1.25% (subject to adjustment if the Consolidated Total Leverage Ratio, as defined in the Credit Agreement, is at or greater than 2.25 to 1). Initially, swingline loans bear interest at the LIBOR Market Index Rate plus 2.00%. Interest on each loan featuring the base rate or the LIBOR Market Index Rate is due and payable on the last business day of each calendar month; interest on each loan featuring the LIBOR Rate is due and payable on the last day of each interest period selected by us when selecting the LIBOR Rate as the benchmark for interest calculation. For purposes of the Credit Agreement, the base rate means the highest of (i) the prime rate (as announced by Wells Fargo), (ii) the federal funds rate plus 0.50%, and (iii) LIBOR for an interest period of one month plus 1.00%. Our obligations under the Credit Agreement and all loans made thereunder are fully secured by a security interest in our assets pursuant to a separate collateral agreement entered into in conjunction with the Credit Agreement.

The Credit Agreement contains covenants, representations and warranties and other terms customary for revolving credit loans of this nature. In this regard, the Credit Agreement requires us to not, among other things, (a) permit the Consolidated Total Leverage Ratio (as defined in the Credit Agreement) to be greater than 4.75 to 1 through the end of 2013, no more than 4.00 to 1 as of the fiscal quarter ending March 31, 2014, no more than 3.75 to 1 as of the fiscal quarter ending June 30, 2014, no more than 3.50 to 1 as of the fiscal quarter ending September 30, 2014, no more than 3.25 to 1 as of the fiscal quarter ending December 31, 2014, no more than 3.00 to 1 as of any fiscal quarter ending during 2015, no more than 2.75 to 1 as of any fiscal quarter ending during 2016, and no more than 2.50 to 1 as of any fiscal quarter ending thereafter; (b) for any period of four consecutive fiscal quarters, permit the ratio of Consolidated EBITDA (as defined in the Credit Agreement and subject to certain adjustments) to Consolidated Fixed Charges (as defined in the Credit Agreement) to be less than 1.75 to 1; (c) subject to certain adjustments, permit Consolidated Net Income (as defined in the Credit Agreement) for certain periods to be less than $0; or (d) subject to certain conditions and adjustments, permit the aggregate amount of all Facility Capital Expenditures (as defined in the Credit Agreement) in any fiscal year beginning in 2013 to exceed $30 million. Additionally, the Credit Agreement contains various negative covenants with which we must comply, including, but not limited to, limitations respecting: the incurrence of indebtedness, the creation of liens or pledges on our assets, mergers or similar combinations or liquidations, asset dispositions, the repurchase or redemption of equity interests or debt, the issuance of equity, the payment of dividends and certain distributions, the entry into related party transactions and other provisions customary in similar types of agreements. As of March 31, 2015, we were in compliance with all covenants set forth in the Credit Agreement.

We had originally entered into an unsecured credit agreement, dated September 30, 2010, with certain lenders who were or became party thereto and Wells Fargo, as administrative agent for the lenders. Pursuant to the terms of that credit agreement, the lenders agreed to make revolving credit loans up to an aggregate amount of $175 million. Wells Fargo also agreed to make swingline loans from time to time through the maturity date of September 10, 2015 in amounts equal to the difference between the amount actually loaned by the lenders and the aggregate credit agreement. The unsecured credit agreement was amended and restated as of December 19, 2012, as the Credit Agreement.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-based Compensation

Stock-Based Compensation. Stock-based compensation expense before income tax expense for the three-month periods ended March 31, 2015 and 2014, consisted of the following (in thousands):

	2015		2014
Cost of goods sold	$	93	$	43
Research and development	27		16
Selling, general, and administrative	400		280
Stock-based compensation expense before taxes	$	520	$	339

As of March 31, 2015, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $6.7 million and is expected to be recognized over a weighted average period of 3.7 years.

During the three months ended March 31, 2015, we granted awards representing 446,800 shares of our common stock. We did not grant any stock-based awards during the three months ended March 31, 2014. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the options granted during the three months ended March 31, 2015, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31, 2015
Risk-free interest rate	1.53%
Expected option life	5.0
Expected dividend yield	—%
Expected price volatility	35.11%

For purposes of the foregoing analysis, the average risk-free interest rate is determined using the U.S. Treasury rate in effect as of the date of grant, based on the expected term of the stock option. The expected term of the stock options is determined using the historical exercise behavior of employees. The expected price volatility is determined using a weighted average of daily historical volatility of our stock price over the corresponding expected option life and implied volatility based on recent trends of the daily historical volatility. Compensation expense is recognized on a straight-line basis over the service period, which corresponds to the related vesting period.
