Basis of presentation. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of only normal recurring adjustments) considered necessary to present fairly the Company’s results of operations, financial position and cash flows have been made. The results of operations and cash flows for the three months ended March 31, 2014, are not necessarily indicative of the results of operations and cash flows that may be reported for the remainder of 2014 or for future periods. The unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2013.

Principles of consolidation. The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of OPKO Health, Inc. and of our wholly-owned subsidiaries and variable interest entities (“VIEs”) in which we are deemed to be the primary beneficiary. All significant intercompany accounts and transactions are eliminated in consolidation.

Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and cash equivalents. Cash and cash equivalents include short-term, interest-bearing instruments with original maturities of 90 days or less at the date of purchase. We also consider all highly liquid investments with original maturities at the date of purchase of 90 days or less as cash equivalents. These investments include money markets, bank deposits, certificates of deposit and U.S. treasury securities.

Inventories. Inventories are valued at the lower of cost or market (net realizable value). Cost is determined by the first-in, first-out method. We consider such factors as the amount of inventory on hand, estimated time required to sell such inventories, remaining shelf-life, and current market conditions to determine whether inventories are stated at the lower of cost or market.

Goodwill and intangible assets. Goodwill represents the difference between the purchase price and the estimated fair value of the net assets acquired when accounted for by the purchase method of accounting and arose from our acquisitions of Pharma Genexx, S.A. (“OPKO Chile”), Pharmacos Exakta S.A. de C.V. (“Exakta-OPKO”), CURNA, Inc. (“CURNA”), Claros Diagnostics, Inc. (“OPKO Diagnostics”), FineTech Pharmaceuticals, Ltd. (“FineTech”), ALS Distribuidora Limitada (“ALS”), Farmadiet Group Holding, S.L. (“OPKO Spain”), Prost-Data, Inc. (“OPKO Lab”), Cytochroma Inc. (“OPKO Renal”), Silcon Comércio, Importacao E Exportacao de Produtos Farmaceuticos e Cosmeticos Ltda. (“OPKO Brazil”) and PROLOR Biotech, Inc. (“OPKO Biologics”). Goodwill, in-process research and development (“IPR&D”) and other intangible assets acquired in business combinations, licensing and other transactions at March 31, 2014 and December 31, 2013 were $1.1 billion and $1.1 billion, respectively.

We amortize intangible assets with definite lives on a straight-line basis over their estimated useful lives, ranging from 3 to 10 years, and review for impairment at least annually, or when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. We use the straight-line method of amortization as there is no reliably determinable pattern in which the economic benefits of our intangible assets are consumed or otherwise used up. Amortization expense from continuing operations was $2.7 million at March 31, 2014 and 2013, respectively.

Fair value measurements. The carrying amounts of our cash and cash equivalents, accounts receivable and accounts payable approximate their fair value due to the short-term maturities of these instruments. Investments that are considered available for sale as of March 31, 2014 are carried at fair value.

Short-term investments, which we invest in from time to time, include bank deposits, corporate notes, U.S. treasury securities and U.S. government agency securities with original maturities of greater than 90 days and remaining maturities of less than one year. Long-term investments include corporate notes, U.S. treasury securities and U.S. government agency securities with maturities greater than one year.

Contingent consideration. Each period we revalue the contingent consideration obligations associated with certain acquisitions to their fair value and record increases in the fair value as contingent consideration expense and decreases in the fair value as contingent consideration income. Changes in contingent consideration result from changes in the assumptions regarding probabilities of successful achievement of related milestones, the estimated timing in which the milestones are achieved and the discount rate used to estimate the fair value of the liability. Contingent consideration may change significantly as our development programs progress, revenue estimates evolve and additional data is obtained, impacting our assumptions. The assumptions used in estimating fair value require significant judgment. The use of different assumptions and judgments could result in a materially different estimate of fair value which may have a material impact on our results from operations and financial position.

Derivative financial instruments. We record derivative financial instruments on our Condensed Consolidated Balance Sheet at their fair value and recognize the changes in the fair value in our Condensed Consolidated Statement of Operations, when they occur, the only exception being derivatives that qualify as hedges. For the derivative instrument to qualify as a hedge, we are required to meet strict hedge effectiveness and contemporaneous documentation requirements at the initiation of the hedge and assess the hedge effectiveness on an ongoing basis over the life of the hedge. At March 31, 2014 and December 31, 2013, our forward contracts for inventory purchases did not meet the documentation requirements to be designated as hedges. Accordingly, we recognize all changes in the fair values of our derivatives instruments, net, in our Condensed Consolidated Statement of Operations. Refer to Note 9.

Revenue recognition. Generally, we recognize revenue from product sales when goods are shipped and title and risk of loss transfer to our customers. Our estimates for sales returns and allowances are based upon the historical patterns of product returns and allowances taken, matched against the sales from which they originated, and management’s evaluation of specific factors that may increase or decrease the risk of product returns.

Revenue for laboratory services is recognized on the accrual basis at the time test results are reported, which approximates when services are provided. Services are provided to certain patients covered by various third-party payer programs including various managed care organizations, as well as the Medicare and Medicaid programs. Billings for services under third-party payer programs are included in sales net of allowances for contractual discounts and allowances for differences between the amounts billed and estimated program payment amounts. Adjustments to the estimated payment amounts based on final settlement with the programs are recorded upon settlement as an adjustment to revenue. For the three months ended March 31, 2014 and 2013, revenue from services also includes $0.1 million and $0.2 million, respectively, of revenue related to our consulting agreement with Neovasc and to revenue related to molecular diagnostics collaboration agreements. We recognize this revenue on a straight-line basis over the contractual term of the agreements.

The assessment of our obligations and related performance periods requires significant management judgment. If an agreement contains research and development obligations, the relevant time period for the research and development phase is based on management estimates and could vary depending on the outcome of clinical trials and the regulatory approval process. Such changes could materially impact the revenue recognized, and as a result, management reviews the estimates related to the relevant time period of research and development on a quarterly basis. For the three months ended March 31, 2014, we recorded $0.5 million of revenue from the transfer of intellectual property. Refer to Note 5.

Total deferred revenue included in Accrued expenses and Other long-term liabilities was $8.6 million and $8.3 million at March 31, 2014 and December 31, 2013, respectively.

Allowance for doubtful accounts. We analyze accounts receivable and historical bad debt levels, customer credit worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts using the specific identification method. Our reported net loss is directly affected by our estimate of the collectability of accounts receivable. The amount of the allowance for doubtful accounts was $1.6 million and $1.9 million at March 31, 2014 and December 31, 2013, respectively.

Equity-based compensation. We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized in the Condensed Consolidated Statement of Operations over the period during which an employee is required to provide service in exchange for the award. We record excess tax benefits, realized from the exercise of stock options as a financing cash inflow rather than as a reduction of taxes paid in cash flow from operations. Equity-based compensation arrangements to non-employees are recorded at their fair value on the measurement date. The measurement of equity-based compensation is subject to periodic adjustment as the underlying

equity instruments vest. During the three months ended March 31, 2014 and 2013, we recorded $3.6 million and $5.2 million, respectively, of equity-based compensation expense.

Research and development expenses. Research and development expenses include external and internal expenses, partially offset by third-party grants and fundings arising from collaboration agreements. External expenses include clinical and non-clinical activities performed by contract research organizations, lab services, purchases of drug and diagnostic product materials and manufacturing development costs. Research and development employee-related expenses include salaries, benefits and stock-based compensation expense. Other unallocated internal research and development expenses are incurred to support overall research and development activities and include expenses related to general overhead and facilities. We expense these costs in the period in which they are incurred. We estimate our liabilities for research and development expenses in order to match the recognition of expenses to the period in which the actual services are received. As such, accrued liabilities related to third party research and development activities are recognized based upon our estimate of services received and degree of completion of the services in accordance with the specific third party contract.

Segment reporting. Our chief operating decision-maker (“CODM”) is comprised of our executive management with the oversight of our Board of Directors. Our CODM reviews our operating results and operating plans and makes resource allocation decisions on a Company-wide or aggregate basis. We currently manage our operations in two reportable segments, pharmaceuticals and diagnostics. The pharmaceutical segment consists of two operating segments, our (i) pharmaceutical research and development segment which is focused on the research and development of pharmaceutical products, and vaccines, and (ii) the pharmaceutical operations we acquired in Chile, Mexico, Israel, Spain, Uruguay and Brazil. The diagnostics segment consists of two operating segments, our (i) pathology operations we acquired through the acquisition of OPKO Lab and (ii) point-of-care and molecular diagnostics operations. There are no inter-segment sales. We evaluate the performance of each segment based on operating profit or loss. There is no inter-segment allocation of interest expense and income taxes.

Variable interest entities. The consolidation of variable interest entities (“VIE”) is required when an enterprise has a controlling financial interest. A controlling financial interest in a VIE will have both of the following characteristics: (a) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE. Refer to Note 5.

Investments. We have made strategic investments in development stage and emerging companies. We record these investments as equity method investments or investments available for sale based on our percentage of ownership and whether we have significant influence over the operations of the investees. For investments classified under the equity method of accounting, we record our proportionate share of their losses in Losses from investments in investees in our Condensed Consolidated Statement of Operations. Refer to Note 5. For investments classified as available for sale, we record changes in their fair value as unrealized gain or loss in Other comprehensive loss based on their closing price per share at the end of each reporting period. Refer to Note 5.

Recent accounting pronouncements. In July 2013, the FASB issued an Accounting Standards Update (“ASU”), ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 is intended to eliminate inconsistent practices regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is available to reduce the taxable income or tax payable that would result from the disallowance of a tax position. ASU 2013-11 is effective for our fiscal year beginning January 1, 2014 and subsequent interim periods. The adoption of ASU 2013-11 does not have a material effect on our Condensed Consolidated Financial Statements.

Basic loss per share is computed by dividing our net loss by the weighted average number of shares outstanding during the period. Diluted loss per share is computed by dividing our net loss increased by dividends on preferred stock by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. In the periods in which their effect would be anti-dilutive, no effect has been given to outstanding options, warrants or convertible Preferred Stock in the diluted computation. Potentially dilutive shares issuable pursuant to the 2033 Senior Notes (defined in Note 6) were not included in the computation of net loss per share for the three months ended March 31, 2014, because their inclusion would be anti-dilutive.

Also, a total of 29,874,112 and 30,119,145 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the three months ended March 31, 2014 and 2013, respectively, because their inclusion would be anti-dilutive.

During the three months ended March 31, 2014, 602,665 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 527,926 shares of Common Stock. Of the 602,665 Common Stock options and Common Stock warrants exercised, 74,739 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the warrant agreements.

At March 31, 2014, the changes in value of the intangible assets and goodwill are primarily due to foreign currency fluctuations between the Chilean and Mexican pesos, the Euro and the Shekel against the U.S. dollar.

The following table summarizes the changes in Goodwill during the three months ended March 31, 2014.

Under the terms of the Merger Agreement, holders of PROLOR common stock received 0.9951 shares of our Common Stock for each share of PROLOR common stock. At closing, we delivered 63,670,805 shares of our Common Stock valued at $540.6 million based on the closing price per share of our Common Stock as reported by the NYSE on the closing date of the acquisition, or $8.49 per share. In addition, each outstanding option and warrant to purchase shares of PROLOR common stock that was outstanding and unexercised immediately prior to the closing date, whether vested or not vested, was converted into 7,889,265 options and warrants to purchase OPKO Common Stock at a fair value of $46.1 million.

Until completion of the acquisition, Dr. Phillip Frost, our Chairman and Chief Executive Officer, was PROLOR’s Chairman of the Board and owned greater than 5% of its stock. Dr. Jane H. Hsiao, our Vice Chairman and Chief Technology Officer, and Mr. Steven Rubin, our Executive Vice President, Administration, were both directors of PROLOR and owned less than 5% of its stock.

In March 2013, we acquired OPKO Renal (formerly Cytochroma, Inc.), whose lead products, both in Phase 3 development, are Rayaldee^TM (CTAP101), a vitamin D prohormone to treat secondary hyperparathyroidism in patients with stage 3 or 4 CKD and vitamin D insufficiency, and Alpharen^TM (Fermagate Tablets), a non-absorbed phosphate binder to treat hyperphosphatemia in dialysis patients (the “OPKO Renal Acquisition”).

In connection with the OPKO Renal Acquisition, we delivered 20,517,030 of shares of our Common Stock valued at $146.9 million based on the closing price per share of our Common Stock as reported by the NYSE on the actual closing date of the acquisition, or $7.16 per share. The number of shares issued was based on the volume-weighted average price per share of our Common Stock as reported on the NYSE for the 10 trading days immediately preceding the date of the purchase agreement for the OPKO Renal Acquisition, or $4.87 per share.

In addition, the OPKO Renal Acquisition requires payments of up to an additional $190.0 million in cash or additional shares of our Common Stock, at our election, upon the achievement of certain milestones relating to development and annual revenue. As a result, we recorded $47.7 million as contingent consideration at acquisition. We evaluate the contingent consideration on an ongoing basis and the changes in the fair value are recognized in earnings until the milestones are achieved. Refer to Note 8.

(1)Current assets include cash of $0.4 million and $20.5 million related to the OPKO Renal and OPKO Biologics acquisitions, respectively.

The following table includes the pro forma results for the three months ended March 31, 2013 of the combined companies as though the acquisition of OPKO Renal and OPKO Biologics had been completed as of the beginning of the period presented.

The total assets, liabilities, and net losses of our equity method investees for three months ended March 31, 2014 were $119.1 million, $41.2 million, and $12.5 million, respectively. The following table reflects our maximum exposure, accounting method, ownership interest and underlying equity in net assets of each of our unconsolidated investments as of March 31, 2014:

We previously made investments in Biozone Pharmaceuticals, Inc. (“Biozone”) and Cocrystal Discovery, Inc. (“Cocrystal”). Effective January 2, 2014, Biozone and Cocrystal completed a merger transaction pursuant to which Cocrystal was the surviving entity, and the name of the issuer was changed to Cocrystal Pharma, Inc. (“CPI”). In connection with the transaction, CPI issued to Cocrystal’s former security holders 1,000,000 shares of the CPI’s Series B Convertible Preferred Stock (“Series B”). The Series B shares: (i) automatically convert into shares of the CPI’s common stock at a rate of 205.08308640 shares for each share of Series B at such time that CPI has sufficient authorized capital, (ii) are entitled to vote on all matters submitted to shareholders of CPI and vote on an as converted basis and (iii) have a nominal liquidation preference. The merger was being treated as a reverse merger and recapitalization effected by a share exchange for financial accounting and reporting purposes since substantially all of the former Biozone’s operations were disposed of immediately

In October 2013, we made an investment in ARNO Therapeutics, Inc. (“ARNO”), a clinical stage company focused on the development of oncology drugs. We invested $2.0 million and received 833,333 ARNO common shares, one year warrants to purchase 833,333 ARNO common shares for $2.40 a share and five year warrants to purchase an additional 833,333 ARNO common shares for $4.00 a share. Our investment was part of a private placement by ARNO. Other investors participating in the private financing included certain related parties. Refer to Note 10. We have determined that our ownership, along with that of our related parties, does not provide us with significant influence over the operations of ARNO and as a result, we account for ARNO as an investment, available for sale, and we record changes in the fair value of ARNO as an unrealized gain or loss in Other comprehensive loss each reporting period. We recorded the warrants on the date of the grant at their estimated fair value of $3.6 million using the Black-Scholes-Merton Model. We record changes in fair value of ARNO warrants in Other income (expense), net in our Condensed Consolidated Statement of Operations.

In 2011, we made an investment in Neovasc, a medical technology company based in Vancouver, Canada. We invested $2.0 million and received two million Neovasc common shares, and two-year warrants to purchase an additional one million shares for $1.25 a share. During the year ended December 31, 2013 we exercised the warrants and paid $1.2 million. We accounted for the warrants as an investment, available for sale and recorded the warrants at fair value on the date of acquisition. We recorded the changes in the fair value of the warrants in Fair value changes of derivatives instruments, net in our Condensed Consolidated Statements of Operations. We have determined that our related parties can significantly influence the success of Neovasc through our board representation and voting power. Accordingly, as we and our related parties have the ability to exercise significant influence over Neovasc’s operations, we account for our investment in Neovasc under the equity method.

•We delivered approximately $9.6 million to Pharmsynthez.

•Pharmsynthez issued to us approximately 13.6 million of its common shares.

•Pharmsynthez agreed, at its option, to issue approximately 12.0 million common shares to us or to pay us RussianRubles (“RUR”) 265.0 million ($8.1 million) on or before December 31, 2013 (the “Pharmsynthez Note Receivable”). In January 2014, Pharmsynthez delivered to us approximately 12.0 million shares of its common stock in satisfaction of the Pharmsynthez Notes Receivable.

• We had a right to purchase additional shares in Pharmsynthez at a fixed price if Pharmsynthez pays us in cash rather than delivering to us the 12.0 million Pharmsynthez common shares (the “Purchase Option”), however in connection with the settlement of the Pharmsynthez Note Receivable in January 2014, this right terminated. 

• We granted rights to certain technologies in the Russian Federation, Ukraine, Belorussia, Azerbaidjan and Kazakhstan (the “Territories”) to Pharmsynthez. 

•We will receive from Pharmsynthez royalty on net sales of products incorporating the technologies in the Territories, as well as a percentage of any sublicense income from third parties for the technologies in the Territories.

•Pharmsynthez paid us $9.5 million under the various collaboration and funding agreements for the development of the technologies (the “Collaboration Payments”).

We have accounted for the license and development activities as a multi-element arrangement, and allocated the total arrangement consideration based on the relative selling prices of the elements. We will record the allocated consideration for development activities as an offset to Research and development expenses over the three-year term of the Collaboration Payments.  We will record revenue in connection with the grant of rights to the technologies proportionately as the payments are received. 

During the three months ended March 31, 2014, we received $1.4 million related to the Collaboration Payments of which we recorded $0.5 million in Revenue from transfer of intellectual property and $0.4 million as an offset to Research and development expenses.

In March 2013, we completed the sale to RXi Pharmaceuticals, Inc. (“RXi”) of substantially all of our assets in the field of RNA interference (the “RNAi Assets”) (collectively, the “Asset Purchase Agreement”). As consideration for the RNAi Assets, at the closing of the Asset Purchase Agreement, RXi issued to us 50 million shares of its common stock (the “APA Shares”).

Pursuant to the Asset Purchase Agreement, RXi will be required to pay us up to $50.0 million in milestone payments upon the successful development and commercialization of each drug developed by RXi, certain of its affiliates or any of its or their licensees or sublicensees utilizing patents included within the RNAi Assets (each, a “Qualified Drug”). In addition, RXi will also be required to pay us royalties equal to: (a) a mid single-digit percentage of “Net Sales” (as defined in the Asset Purchase Agreement) with respect to each Qualified Drug sold for an ophthalmologic use during the applicable “Royalty Period” (as defined in the Asset Purchase Agreement); and (b) a low single-digit percentage of net sales with respect to each Qualified Drug sold for a non-ophthalmologic use during the applicable royalty period.

In addition to the Asset Purchase Agreement, we purchased 17,241,380 shares of RXi, for $2.5 million, as part of a $16.4 million financing for RXi, which included other related parties. We have determined that our ownership, along with that of our related parties, provides us the ability to exercise significant influence over RXi operations and as such we have accounted for our investment in RXi under the equity method.

In October 2013, we acquired 840,000 shares of Zebra Series A-2 Preferred Stock for $2.0 million. In connection with the transactions, Dr. Frost also gifted to OPKO 900,000 shares of Zebra restricted common stock which he had received as a founding member of Zebra. Zebra is a privately held biotechnology company focused on the discovery and development of biosuperior antibody therapeutics and complex drugs. After the closing on October 29, 2013, OPKO owns 23.5% of the Series A-2 Preferred stock issued and outstanding of Zebra. Dr. Richard Lerner, M.D., a member of our Board of Directors, is a founder of Zebra and, along with Dr. Frost, serves as a member of Zebra’s Board of Directors.

In June 2012, we entered into a share and debt purchase agreement whereby in exchange for $0.7 million we acquired shares representing a 50% stock ownership in SciVac from FDS Pharma LLP (“FDS”). SciVac is a privately-held Israeli company that produces a third-generation hepatitis B-vaccine. From November 2012 until March 31, 2014, we loaned to SciVac a combined $2.5 million for working capital purposes. We have determined that we hold variable interests in SciVac based on our assessment that SciVac does not have sufficient resources to carry out its principal activities without financial support. In order to determine the fair market value of our investment in SciVac, we have utilized a business enterprise valuation approach.

In order to determine the primary beneficiary of SciVac, we evaluated our investment to identify if we had the power to direct the activities that most significantly impact the economic performance of SciVac. We have determined that the power to direct the activities that most significantly impact the economic performance of SciVac is conveyed through SciVac’s board of directors. SciVac’s board of directors appoint and oversee SciVac’s management team who carry out the activities that most significantly impact the economic performance of SciVac. As part of the share and debt purchase agreement, SciVac’s board of directors is constituted by 5 members, of which 3 members will be appointed by us, representing 60% of SciVac’s board. Based on this analysis, we determined that we have the power to direct the activities of SciVac and as such we are the primary beneficiary. As a result of this conclusion, we have consolidated the results of operations and financial position of SciVac and recorded a reduction of equity for the portion of SciVac we do not own.

The following table represents the consolidated assets and non-recourse liabilities related to SciVac as of March 31, 2014 and December 31, 2013. These assets are owned by, and these liabilities are obligations of, SciVac, not us.

In January 2013, we entered into note purchase agreements (the “2033 Senior Notes”) with qualified institutional buyers and accredited investors (collectively the “Purchaser”) in a private placement in reliance on exemptions from registration under the Securities Act of 1933, (the “Securities Act”). The Purchasers of the 2033 Senior Notes include Frost Gamma Investments Trust, a trust affiliated with Dr. Frost, and Hsu Gamma Investment, L.P., an entity affiliated with Dr. Hsiao. The 2033 Senior Notes were issued on January 30, 2013. The 2033 Senior Notes, which total $175.0 million, bear interest at the rate of 3.00% per year, payable semiannually on February 1 and August 1 of each year, beginning August 1, 2013. The 2033 Senior Notes will mature on February 1, 2033, unless earlier repurchased, redeemed or converted. Upon a fundamental change as defined in the instruments governing the 2033 Senior Notes, subject to certain exceptions, the holders may require us to repurchase all or any portion of their 2033 Senior Notes for cash at a repurchase price equal to 100% of the principal amount of the 2033 Senior Notes being repurchased, plus any accrued and unpaid interest to but not including the fundamental change repurchase date.
