CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements,” as that term is defined under the Private Securities Litigation Reform Act of 1995 (“PSLRA”), Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include statements about our expectations, beliefs or intentions regarding our product development efforts, business, financial condition, results of operations, strategies or prospects. You can identify forward-looking statements by the fact that these statements do not relate strictly to historical or current matters. Rather, forward-looking statements relate to anticipated or expected events, activities, trends or results as of the date they are made. Because forward-looking statements relate to matters that have not yet occurred, these statements are inherently subject to risks and uncertainties that could cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements. Many factors could cause our actual activities or results to differ materially from the activities and results anticipated in forward-looking statements. These factors include those described below and in “Item 1A-Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2012, as updated by our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013, and described from time to time in our other reports filed with the Securities and Exchange Commission. Except as required by law, we do not undertake any obligation to update forward-looking statements. We intend that all forward-looking statements be subject to the safe-harbor provisions of the PSLRA. These forward-looking statements are only predictions and reflect our views as of the date they are made with respect to future events and financial performance.

Risks and uncertainties, the occurrence of which could adversely affect our business, include the following:

• We have a history of operating losses and we do not expect to become profitable in the near future.

• Our technologies are in an early stage of development and are unproven.

• Our business is substantially dependent on our ability to develop, launch and generate revenue from our pharmaceutical and diagnostic programs.

• Our research and development activities may not result in commercially viable products.

• The results of previous clinical trials may not be predictive of future results, and our current and planned clinical trials may not satisfy the requirements of the FDA or other non-U.S. regulatory authorities.

• We may require substantial additional funding, which may not be available to us on acceptable terms, or at all.

• We may finance future cash needs primarily through public or private offerings, debt financings or strategic collaborations, which may dilute your stockholdings in the Company.

• If our competitors develop and market products that are more effective, safer or less expensive than our future product candidates, our commercial opportunities will be negatively impacted.

• The regulatory approval process is expensive, time consuming and uncertain and may prevent us or our collaboration partners from obtaining approvals for the commercialization of some or all of our product candidates.

• Failure to recruit and enroll patients for clinical trials may cause the development of our product candidates to be delayed.

• Even if we obtain regulatory approvals for our product candidates, the terms of approvals and ongoing regulation of our products may limit how we manufacture and market our product candidates, which could materially impair our ability to generate anticipated revenues.

• We may not meet regulatory quality standards applicable to our manufacturing and quality processes.

• Even if we receive regulatory approval to market our product candidates, the market may not be receptive to our products.

• The loss of Phillip Frost, M.D., our Chairman and Chief Executive Officer, could have a material adverse effect on our business and product development.

• If we fail to attract and retain key management and scientific personnel, we may be unable to successfully develop or commercialize our product candidates.

• In the event that we successfully evolve from a company primarily involved in development to a company also involved in commercialization, we may encounter difficulties in managing our growth and expanding our operations successfully.

•

3

• Failure to close the proposed merger with PROLOR Biotech, Inc. could have a negative impact on the Company and our financial condition, results of operations, cash flows and stock price.

• If we fail to acquire and develop other products or product candidates, at all or on commercially reasonable terms, we may be unable to diversify or grow our business.

• We have no experience manufacturing our pharmaceutical product candidates other than at our Israeli, Mexican, and Spanish facilities and we therefore rely on third parties to manufacture and supply our pharmaceutical product candidates, and would need to meet various standards necessary to satisfy FDA regulations if and when we commence manufacturing.

• We currently have no pharmaceutical or diagnostic marketing, sales or distribution capabilities other than in Chile, Mexico, Spain, and Brazil for sales in those countries and our active pharmaceutical ingredients (“APIs”) business in Israel, and the sales force for our laboratory business based in Nashville, Tennessee. If we are unable to develop our sales and marketing and distribution capability on our own or through collaborations with marketing partners, we will not be successful in commercializing our pharmaceutical and diagnostic product candidates.

• The success of our business will be heavily dependent on the success of ongoing and planned Phase 3 clinical trials for Rayaldy^TM and Alpharen^TM.

• Independent clinical investigators and contract research organizations that we engage to conduct our clinical trials may not be diligent, careful or timely.

• The success of our business is dependent on the actions of our collaborative partners.

• Our license agreement with TESARO, Inc. (“TESARO”) is important to our business. If TESARO does not successfully develop and commercialize rolapitant, our business could be adversely affected.

• If we are unable to obtain and enforce patent protection for our products, our business could be materially harmed.

• We do not have an exclusive arrangement in place with Dr. Tom Kodadek with respect to technology or intellectual property that may be material to our business.

• If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology and products could be adversely affected.

• We rely heavily on licenses from third parties.

• We license patent rights to certain of our technology from third-party owners. If such owners do not properly maintain or enforce the patents underlying such licenses, our competitive position and business prospects will be harmed.

• Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties.

• Adverse results in material litigation matters or governmental inquiries could have a material adverse effect upon our business and financial condition.

• Medicare prescription drug coverage legislation and future legislative or regulatory reform of the health care system may affect our ability to sell our products and provide our services profitably.

• Failure to obtain and maintain regulatory approval outside the United States will prevent us from marketing our product candidates abroad.

• We may not have the funding available to pursue acquisitions.

• Acquisitions may disrupt our business, distract our management, may not proceed as planned, and may also increase the risk of potential third party claims and litigation.

• We may encounter difficulties in integrating acquired businesses.

• Non-U.S. governments often impose strict price controls, which may adversely affect our future profitability.

• Political and economic instability in Europe and Latin America and political, economic, and military instability in Israel could adversely impact our operations.

• We are subject to fluctuations in currency exchange rates in connection with our international businesses.

4

• Our business may become subject to legal, economic, political, regulatory and other risks associated with international operations.

• The market price of our Common Stock may fluctuate significantly.

• Directors, executive officers, principal stockholders and affiliated entities own a significant percentage of our capital stock, and they may make decisions that you may not consider to be in your best interests or in the best interests of our stockholders.

• Compliance with changing regulations concerning corporate governance and public disclosure may result in additional expenses.

• If we are unable to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as they apply to us, or our internal controls over financial reporting are not effective, the reliability of our financial statements may be questioned and our Common Stock price may suffer.

• We may be unable to maintain our listing on the NYSE, which could cause our stock price to fall and decrease the liquidity of our Common Stock.

• Future issuances of Common Stock and hedging activities may depress the trading price of our Common Stock.

• Provisions in our charter documents and Delaware law could discourage an acquisition of us by a third party, even if the acquisition would be favorable to you.

• We do not intend to pay cash dividends on our Common Stock in the foreseeable future.

We are developing a range of solutions to diagnose, treat and prevent various conditions, including molecular diagnostics tests, laboratory developed tests, point-of-care tests, and proprietary pharmaceuticals and vaccines. We plan to commercialize these solutions on a global basis in large and high growth markets, including emerging markets.

We own established pharmaceutical platforms in Spain, Chile and Mexico, which are generating revenue and which we expect to generate positive cash flow and facilitate future market entry for our products currently in development. In addition, we recently established pharmaceutical operations in Brazil. We also operate a specialty active pharmaceutical ingredients (“APIs”) manufacturer in Israel, which we expect to play a valuable role in the development of our pipeline of molecules and compounds for our proprietary molecular diagnostic and therapeutic products. We operate a laboratory business with laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”), that has a strong presence in the U.S. urologic pathology market, and will provide us with a platform to commercialize certain of our novel diagnostics tests currently in development. We also own an interest in a biopharmaceutical company that develops, manufactures and markets recombinant human health care biotechnology derived products in Israel and whose principal marketed product is a novel third generation Hepatitis B vaccine currently being commercialized in Israel, India and Hong Kong.

We are incorporated in Delaware and our principal executive offices are located in leased offices in Miami, Florida. We lease office and lab space in Jupiter and Miramar, Florida, which is where our molecular diagnostics research and development and oligonucleotide research and development operations are based, respectively. We lease office, manufacturing and warehouse space in Woburn, Massachusetts for our point-of-care diagnostics business, and in Nesher, Israel for our API business. We lease laboratory and office space in Nashville, Tennessee and Burlingame, California for our CLIA-certified laboratory business, and we lease office space in Bannockburn, Illinois, and Markham, Ontario and laboratory space in Toronto, Ontario for our pharmaceutical business directed to chronic kidney disease. Our Chilean operations are located in leased offices and warehouse facilities in Santiago. Our Mexican operations are based in owned offices, an owned manufacturing facility and a leased warehouse facility in Guadalajara and in leased offices in Mexico City. Our Spanish operations are based in owned offices in Barcelona, in an owned manufacturing facility in Banyoles and a leased warehouse facility in Palol de Revardit. Our Brazilian operations are located in leased offices in Sao Paulo.

NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 and six months ended June 30, 2013, are not necessarily indicative of the results of operations and cash flows that may be reported for the remainder of 2013 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, 2012.

Reclassifications. Certain prior year amounts in the condensed consolidated financial statements have been reclassified to conform with the 2013 presentation. Due to the acquisition of OPKO OURLab, LLC (formerly Prost-Data, Inc.), our CLIA-certified laboratory business (“OURLab”) in December 2012, we changed our segment presentation to include diagnostics as a reportable segment. As a result of this change in reportable segments, we restated certain prior year amounts in the condensed consolidated financial statements to conform with the 2013 presentation. These reclassifications had no impact on our results of operations. Refer to Note 12.

Principles of consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of OPKO Health, Inc., 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

11

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. Goodwill and other intangible assets acquired in business combinations, licensing and other transactions at June 30, 2013 and December 31, 2012 were $364.9 million and $176.2 million, respectively.

Assets acquired and liabilities assumed in business combinations, licensing and other transactions are recognized at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recognized as goodwill. We determined the fair value of intangible assets, including in-process research and development (“IPR&D”), using the “income method.”

Goodwill is tested at least annually for impairment, or when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, on an enterprise level by assessing qualitative factors or performing a quantitative analysis in determining whether it is more likely than not that its fair value exceeds the carrying value.

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 June 30, 2013 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.

In evaluating the fair value information, considerable judgment is required to interpret the market data used to develop the estimates. The use of different market assumptions and/or different valuation techniques may have a material effect on the estimated fair value amounts. Accordingly, the estimates of fair value presented herein may not be indicative of the amounts that could be realized in a current market exchange. Refer to Note 8.

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 June 30, 2013 and December 31, 2012, 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 in Fair value changes of 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

12

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 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 and six months ended June 30, 2013, revenue from services also includes $0.2 million and $0.4 million, respectively, of revenue related to our consulting agreement with Neovasc, Inc. (“Neovasc”) and to revenue related to molecular diagnostics collaboration agreements. For the three and six months ended June 30, 2012, revenue from services included $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.

Revenue from transfer of intellectual property includes revenue related to the sale, license or transfer of intellectual property such as upfront license payments, license fees and milestone payments received through our license, collaboration and commercialization agreements. We analyze our multiple-element arrangements to determine whether the elements can be separated and accounted for individually as separate units of accounting.

Non-refundable license fees for the out-license of our technology are recognized depending on the provisions of each agreement. We recognize non-refundable upfront license payments as revenue upon receipt if the license has standalone value and the fair value of our undelivered obligations, if any, can be determined. If the license is considered to have standalone value but the fair value of any of the undelivered items cannot be determined, the license payments are recognized as revenue over the period of our performance for such undelivered items or services. License fees with ongoing involvement or performance obligations are recorded as deferred revenue, included in Accrued expenses or Other long-term liabilities, when received and generally are recognized ratably over the period of such performance obligation only after both the license period has commenced and we have delivered the technology.

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 six months ended June 30, 2013, we recorded $14.8 million of revenue from the transfer of intellectual property, of which $12.5 million related to the sale of substantially all of our assets in the field of RNA interference to RXi Pharmaceuticals Corporation (“RXi”) during the first quarter of 2013. Refer to Note 5.

Revenue from milestone payments related to arrangements under which we have continuing performance obligations are recognized as Revenue from transfer of intellectual property upon achievement of the milestone only if all of the following conditions are met: the milestone payments are non-refundable; there was substantive uncertainty at the date of entering into the arrangement that the milestone would be achieved; the milestone is commensurate with either the vendor’s performance to achieve the milestone or the enhancement of the value of the delivered item by the vendor; the milestone relates solely to past performance; and the amount of the milestone is reasonable in relation to the effort expended or the risk associated with the achievement of the milestone. If any of these conditions are not met, the milestone payments are not considered to be substantive and are, therefore, deferred and recognized as Revenue from transfer of intellectual property over the term of the arrangement as we complete our performance obligations.

Total deferred revenue included in Accrued expenses and Other long-term liabilities was $6.0 million and $1.9 million at June 30, 2013 and December 31, 2012, 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 $0.9 million and $0.5 million at June 30, 2013 and December 31, 2012, 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 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

13

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 June 30, 2013 and 2012, we recorded $1.8 million and $1.0 million, respectively, of equity-based compensation expense. During the six months ended June 30, 2013 and 2012, we recorded $7.0 million and $2.2 million, respectively, of equity-based compensation expense.

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 pharmaceuticals 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 and Brazil. The diagnostics segment consists of two operating segments, our (i) pathology operations we acquired through the acquisition of OURLab 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 VIEs 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 February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, (“ASU 2013-2”). ASU 2013-2 requires the presentation of reclassifications out of accumulated other comprehensive income in either (1)the notes or (2)the face of the financial statements. We adopted ASU 2013-2 for our first quarter ended March 31, 2013. The adoption of ASU 2013-2 did not have a material impact in our condensed consolidated financial statements, but did require certain additional disclosures. Refer to Note 7.

NOTE 3 LOSS PER SHARE

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 by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of common stock options and common stock warrants is determined by applying the “treasury stock” method. Potentially dilutive shares issuable pursuant to the Notes (defined in Note 6) were not included in the computation of net loss per share for the three and six months ended June 30, 2013, because their inclusion would be anti-dilutive.

Also, a total of 29,701,838 and 27,416,029 potential shares of Common Stock have been excluded from the calculation of net loss per share for the three months ended June 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive. A total of 29,910,492 and 27,243,783 potential shares of Common Stock have been excluded from the calculation of net loss per share for the six months ended June 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive.

During the three months ended June 30, 2013, 216,053 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised and issued.

During the six months ended June 30, 2013, 1,727,746 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 1,612,232 shares of Common Stock. Of the 1,727,746 Common Stock options and Common Stock warrants exercised, 115,514 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the warrant agreements.

(“Cytochroma”), as well as the foreign currency fluctuations between

15

the Chilean and Mexican pesos, the Brazilian Reals, the Euro and the Shekel against the U.S. dollar at June 30, 2013 and December 31, 2012.

NOTE 5 ACQUISITIONS, INVESTMENTS, AND LICENSES

PROLOR acquisition

In April 2013, we entered into an Agreement and Plan of Merger (the “PROLOR Merger Agreement”) pursuant to which we will acquire PROLOR Biotech, Inc. (“PROLOR”), a biopharmaceutical company focused on developing and commercializing longer-acting proprietary versions of already approved therapeutic proteins, in an all-stock transaction. Under the terms of the agreement, holders of PROLOR common stock will receive 0.9951 shares of our Common Stock for each share of PROLOR common stock. Based on a price of $7.03 per share of our Common Stock, the transaction is valued at approximately $480 million, or $7.00 per share of PROLOR common stock. The companies expect the transaction to be completed during the second half of 2013. Closing of the transaction is subject to certain conditions including, the approval of PROLOR’s and our stockholders and other customary closing conditions. Dr. Phillip Frost, our Chairman and Chief Executive Officer, is PROLOR’s Chairman of the Board and a greater than 5% stockholder of PROLOR. Dr. Jane H. Hsiao, our Vice Chairman and Chief Technology Officer and Mr. Steven Rubin, our Executive Vice President, Administration, are both directors of PROLOR and less than 5% stockholders of PROLOR. The Board of Directors of each of OPKO and PROLOR (with the directors noted above abstaining) have approved the Merger and the Merger Agreement. In addition, the transaction was also approved by PROLOR’s Strategic Alternatives Committee.

Cytochroma acquisition

In March 2013, we acquired Cytochroma, a corporation located in Markham, Canada, whose lead products, both in Phase 3 development, are Rayaldy^TM, a vitamin D prohormone to treat secondary hyperparathyroidism in patients with stage 3 or 4 chronic kidney disease and vitamin D insufficiency, and Alpharen^TM, a non-absorbed phosphate binder to treat hyperphosphatemia in dialysis patients (the “Cytochroma Acquisition”).

In connection with the Cytochroma 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 Cytochroma Acquisition, or $4.87 per share. The Cytochroma Agreement contains customary representations, warranties, conditions to closing, indemnification rights and obligations of the parties.

In addition, the Cytochroma 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. 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.

The following table summarizes the estimated fair value of the net assets acquired and liabilities assumed in the acquisition of Cytochroma at the date of acquisition, which are subject to change while contingencies that existed on the acquisition date are resolved:

(In thousands)
Current assets (including cash of $378 thousand)	$	1,224
Intangible assets:
In-process research and development	191,530
Patents	210
Total intangible assets	191,740
Goodwill	2,411
Property, plant and equipment	306
Accounts payable and accrued expenses	(1,069		)
Total purchase price	$	194,612

Goodwill is principally related to the acquired workforce. Goodwill is not tax deductible for income tax purposes.

OPKO Brazil asset acquisition

In February 2013, we acquired the assets of OPKO Brazil, a Brazilian pharmaceutical company, pursuant to a purchase agreement entered into on December 26, 2012. Pursuant to the purchase agreement, we paid $0.3 million in cash and delivered 64,684 shares of our Common Stock at closing valued at $0.4 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 $6.73 per share. The number of shares issued was based on the average closing price per share of Common Stock as reported on the NYSE for the 10 trading days immediately preceding the execution of the purchase agreement, or $4.64 per share.

We accounted for this acquisition as an asset acquisition rather than a business combination. As a result we recorded the assets at fair value, with most of the value being allocated to the most significant asset, its pharmaceutical business licenses.

OURLab acquisition

In October 2012, we entered into a definitive merger agreement to acquire OURLab, a Nashville-based CLIA laboratory. In December 2012, we paid $9.4 million in cash and delivered 7,072,748 shares of our Common Stock at closing valued of $32.9 million based on the closing sales price per share of our Common Stock as reported by the NYSE on the actual closing date of the acquisition, or $4.65 per share. The number of shares issued was based on the average closing price per share of our Common Stock as reported on the NYSE for the 15 trading days immediately preceding the execution of the purchase agreement, or $4.33 per share. Pursuant to the merger agreement, 1,732,102 shares of Common Stock issued in the transaction are being held in a separate escrow account to secure the indemnification obligations of OURLab.

Farmadiet acquisition

In August 2012, we entered into a stock purchase agreement pursuant to which we acquired all of the outstanding stock of Farmadiet Group Holding, S.L. (“Farmadiet”), a Spanish company engaged in the development, manufacture, marketing, and sale of pharmaceutical, nutraceutical, and veterinary products in Europe (the “Farmadiet Transaction”).

In connection with the Farmadiet Transaction, we agreed to pay an aggregate purchase price of €13.5 million (approximately $16.0 million), of which (i) 50% ($8.4 million) was paid in cash at closing, and (ii) 50% (the “Deferred Payments”) will be paid, at our option, in cash or shares of our Common Stock as follows: (x) 25% to be paid on the first anniversary of the closing date; and (y) 25% to be paid 18 months after the closing date. On the date of acquisition, we recorded the €6.8 million Deferred Payments at $7.8 million, net of a discount of $0.6 million. The discount will be amortized as interest expense through the respective payment dates. The Deferred Payments are required to be paid in Euro and as such, the final U.S. dollar amount to be paid will be based on the exchange rate at the time the Deferred Payments are made. In the event we elect to pay the Deferred Payments in shares of our Common Stock, the number of shares issuable shall be calculated using the average closing price per share of our Common Stock as reported on the NYSE for the 10 trading days immediately preceding the applicable payment date. On August 2, 2013, we issued 585,703 shares of our Common Stock, in accordance with the first Deferred Payment. The number of shares issued was based on the average closing price per share of our Common Stock as reported on the NYSE for the 10 trading days up to and including August 1, 2013, or $7.61 per share. We have the right to hold back up to €2.8 million (approximately $3.6 million as of June 30, 2013) from the Deferred Payment to satisfy indemnity claims.

In connection with the Farmadiet Transaction, we also entered into two ancillary transactions (the “Ancillary Transactions”). In exchange for a 40% interest held by one of the sellers in one of Farmadiet’s subsidiaries, we agreed to issue up to an aggregate of 250,000 shares of our Common Stock, of which (a) 125,000 shares were issued on the closing date, and (b) 125,000 will be issued upon achieving certain milestones. In addition, we acquired an interest held by an affiliate of Farmadiet in a product in development in exchange for which we agreed to pay up to an aggregate of €1.0 million ($1.3 million) payable at our option in cash or shares of our Common Stock, of which (a) 25% ($0.3 million) was paid at closing through delivery of 70,421 shares of our Common Stock, and 75% ($1.0 million) will be paid in cash or shares of our Common Stock upon achieving certain milestones. As a result, we recorded $1.2 million as contingent consideration for the future consideration. We evaluate the contingent consideration on an ongoing basis and the changes in fair value are recognized in earnings until the milestones are achieved. Refer to Note 8. The final U.S. dollar amount to be paid will be based on the exchange rate at the time the milestones are achieved. The number of shares of our Common Stock issued is determined based on the average closing sales price for our Common Stock on the NYSE for the 10 trading days preceding the required payment date.

17

ALS acquisition

In April 2012, we completed the acquisition of ALS Distribuidora Limitada (“ALS”), a privately-held Chilean pharmaceutical company, pursuant to a stock purchase agreement entered into in January 2012. In connection with the transaction, we agreed to pay up to a total of $4.0 million in cash to the sellers. Pursuant to the purchase agreement, we paid (i) $2.4 million in cash at the closing, less certain liabilities, and (ii) $0.8 million in cash at the closing into a separate escrow account to satisfy possible indemnity claims. During the six months ended June 30, 2013, we paid the remaining $0.8 million that we had agreed to pay upon the legal registration in the name of ALS of certain trademarks and product registrations previously held by the former owner of ALS, Arama Laboratorios y Compañía Limitada.

Pro forma disclosure for acquisitions

The following table includes the pro forma results for the three and six months ended June 30, 2013 and 2012 of the combined companies as though the acquisition of Cytochroma had been completed as of the beginning of each period, respectively.

Neovasc

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 three months ended June 30, 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.

2013 licensing agreements

An element of our growth strategy is to leverage our proprietary technology through a combination of internal development, acquisition, and external partnerships to maximize the commercial opportunities for our portfolio of proprietary pharmaceutical and diagnostic products.

Pharmsynthez transactions

On April 18, 2013, we entered into a series of concurrent transactions with OAO Pharmsynthez (“Pharmsynthez”), a Russian pharmaceutical company traded on the Moscow Stock Exchange. The transactions consisted of:

•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 shares of its common shares to us or to pay us Russian Rubles (“RUR”) 265.0 million ($8.1 million) on or before December 31, 2013 (the "Pharmsynthez Note Receivable").

• We have 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 shares of Pharmsynthez common shares (the “Purchase Option”). 

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

We recorded the initial shares received in Pharmsynthez as an equity method investment.  We recorded the Pharmsynthez Note Receivable, and the Purchase Option, as financial instruments and elected the fair value option for subsequent measurement. Changes in the fair value of the receivable from Pharmsynthez for its common stock or RUR, with the embedded derivative, and the Purchase Option are recorded in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2013

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.  

RXi transactions

In March 2013, we completed the sale to 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”). In accounting for the sale of the RNAi Assets, we determined that we did not have any continuing involvement in the development of the RNAi Assets or any other future performance obligations and, as a result, during the six months ended June 30, 2013, we recognized the APA Shares as $12.5 million of revenue from transfer of intellectual property in our Condensed Consolidated Statement of Operations.

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

19

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.

Investments in variable interest entities

We have determined that we hold variable interests in Fabrus, Inc. (“Fabrus”), Biozone Pharmaceutical, Inc. (“BZNE”) and SciVac Ltd ("SciVac"), previously known as SciGen (I.L.) Ltd. We made this determination as a result of our assessment that they do not have sufficient resources to carry out their principal activities without additional financial support.

In order to determine the primary beneficiary of BZNE, we evaluated our investment and our related parties’ investments, as well as our investment combined with the related party group’s investments to identify if we had the power to direct the activities that most significantly impact the economic performance of BZNE. We determined that power to direct the activities that most significantly impact BZNE’s economic performance is conveyed through the board of directors of BZNE and no entity is able to appoint the BZNE governing body that oversees its executive management team. Based on the capital structure, governing documents and overall business operations of BZNE, we determined that, while a VIE, no single entity has the power to direct the activities that most significantly impact BZNE’s economic performance. However, we determined that we and our related parties can significantly influence the success of BZNE through our voting power. As such, we account for investment in BZNE under the equity method.

In order to determine the primary beneficiary of Fabrus, we evaluated our investment and our related parties’ investment, as well as our investment combined with the related party group’s investment to identify if we had the power to direct the activities that most significantly impact the economic performance of Fabrus. We determined that power to direct the activities that most significantly impact Fabrus’s economic performance is conveyed through the board of directors of Fabrus as no entity is able to appoint the Fabrus governing body that oversees its executive management team. Based on the capital structure, governing documents and overall business operations of Fabrus, we determined that, while a VIE, no single entity has the power to direct the activities that most significantly impact Fabrus’s economic performance. We did determine, however, that our related parties can significantly influence the success of Fabrus through our board representation and voting power. Accordingly, as we and our related parties have the ability to exercise significant influence over Fabrus’ operations, we account for our investment in Fabrus under the equity method.

Consolidated variable interest entities

In June 2012, we entered into a share and debt purchase agreement whereby in exchange for $0.7 million we acquired shares representing a 45% stock ownership in SciVac from FDS Pharma LLP (“FDS”). SciVac is a privately-held Israeli company that produces a third-generation hepatitis B-vaccine. In November 2012, March 2013 and May 2013, we loaned to SciVac a combined $1.2 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 SciVac and record a reduction of equity for the portion of SciVac we do not own.

NOTE 6 DEBT

In January 2013, we entered into note purchase agreements (the “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 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 Notes were issued on January 30, 2013. The 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 Notes will mature on February 1, 2033, unless earlier repurchased, redeemed or converted. Upon a fundamental change as defined in the instruments governing the Notes, subject to certain exceptions, the holders may require us to repurchase all or any portion of their Notes for cash at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus any accrued and unpaid interest to but not including the fundamental change repurchase date.

The Notes will be convertible at any time on or after November 1, 2032, through the second scheduled trading day immediately preceding the maturity date, at the option of the holders. Additionally, holders may convert their Notes prior to the close of business on the scheduled trading day immediately preceding November 1, 2032, under the following circumstances: (1) conversion based upon satisfaction of the trading price condition relating to the Notes; (2) conversion based on the Common Stock price; (3) conversion based upon the occurrence of specified corporate events; or (4) if we call the Notes for redemption. The Notes will be convertible into cash, shares of our Common Stock, or a combination of cash and shares of Common Stock, at our election unless we have made an irrevocable election of net share settlement. The initial conversion rate for the Notes will be 141.4827 shares of Common Stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $7.07 per share of Common Stock), and will be subject to adjustment upon the occurrence of certain events. In addition, we will, in certain circumstances, increase the conversion rate for holders who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture) and holders who convert upon the occurrence of certain specific events prior to February 1, 2017 (other than in connection with a make-whole fundamental change).

We may not redeem the Notes prior to February 1, 2017. On or after February 1, 2017 and before February 1, 2019, we may redeem for cash any or all of the Notes but only if the last reported sale price of our Common Stock exceeds 130% of the applicable conversion price for at least 20 trading days during the 30 consecutive trading day period ending on the trading day immediately prior to the date on which we deliver the redemption notice. The redemption price will equal 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest to but not including the redemption date. On or after February 1, 2019, we may redeem for cash any or all of the Notes at a redemption price of 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest up to but not including the redemption date.

The terms of the Notes, include, among others: (i) rights to convert into shares of our Common Stock, including upon a fundamental change; and (ii) a coupon make-whole payment in the event of a conversion by the holders of the Notes on or after February 1, 2017 but prior to February 1, 2019. We have determined that these specific terms are considered to be embedded derivatives. As a result, embedded derivatives are required to be separated from the host contract, the Notes, and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; and (b) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. We have concluded that the embedded derivatives within the Notes meet these criteria and, as such, must be valued separate and apart from the Notes and recorded at fair value each reporting period.

For purposes of accounting and financial reporting, we combine these embedded derivatives and value them together as one unit of accounting. At each reporting period, we record these embedded derivatives at fair value which is included as a component of the Notes on our Condensed Consolidated Balance Sheets.

We have used a binomial lattice model in order to estimate the fair value of the embedded derivative in the Notes. A binomial lattice model generates two probable outcomes — one up and another down —arising at each point in time, starting from the date of valuation until the maturity date. A lattice was initially used to determine if the Notes would be converted, called or held at each decision point. Within the lattice model, the following assumptions are made: (i) the Notes will be converted early if the conversion value is greater than the holding value; or (ii) the Notes will be called if the holding value is greater than both (a) the redemption price (as defined in the Indenture) and (b) the conversion value plus the coupon make-whole payment at the time. If the Notes are called, then the holder will maximize their value by finding the optimal decision between (1) redeeming at the redemption price and (2) converting the Notes.

Using this lattice, we valued the embedded derivatives using the “with-and-without method,” where the value of the Notes including the embedded derivatives is defined as the “with,” and the value of the Notes excluding the embedded derivatives is defined as the “without.” This method estimates the value of the embedded derivatives by looking at the

22

difference in the values between the Notes with the embedded derivatives and the value of the Notes without the embedded derivatives.

The lattice model requires the following inputs: (i) price of our Common Stock; (ii) Conversion Rate (as defined in the Indenture); (iii) Conversion Price (as defined in the Indenture); (iv) maturity date; (v) risk-free interest rate; (vi) estimated stock volatility; and (vii) estimated credit spread for the Company.

The following table sets forth the inputs to the lattice model used to value the embedded derivative:

	June 30, 2013			Issuance Date
Stock price	$	7.10		$	6.20
Conversion Rate	141.4827			141.4827
Conversion Price	$	7.07		$	7.07
Maturity date	February 1, 2033			February 1, 2033
Risk-free interest rate	1.57		%	1.12		%
Estimated stock volatility	35		%	40		%
Estimated credit spread	983 basis points			944 basis points

The following table sets forth the fair value of the Notes with and without the embedded derivatives, and the fair value of the embedded derivatives as of the issuance date and June 30, 2013:

(In thousands)	June 30, 2013		Issuance Date
Fair value of Notes:
With the embedded derivatives	$	189,481	$	175,000
Without the embedded derivatives	$	115,402	$	115,796
Estimated fair value of the embedded derivatives	$	74,079	$	59,204

Changes in certain inputs into the lattice model can have a significant impact on changes in the estimated fair value of the embedded derivatives. For example, a decrease in our estimated credit spread results in an increase in the estimated value of the embedded derivatives. Conversely, a decrease in the price of our Common Stock results in a decrease in the estimated fair value of the embedded derivatives. From the date the Notes were issued through June 30, 2013, we observed an increase in the market price of our Common Stock which resulted in a $14.9 million increase in the estimated fair value of our embedded derivatives recorded in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations.

The principal amounts, unamortized discount and net carrying amounts of the Notes as of June 30, 2013 were as follows:

(In thousands)	Principal Balance		Unamortized Discount		Net Carrying Amount
Notes	$	175,000	$	60,555	$	114,445

Amounts reclassified from Accumulated other comprehensive income for the six months ended June 30, 2013 related to $10.8 million realized gain on the sales of certain of our investments available for sale. Of the $10.8 million gain on the sales of our investments available for sale, $5.9 million and $7.5 million gains, respectively, were reclassified from unrealized gains in Accumulated other comprehensive income to Other income (expense), net for the three and six months ended June 30, 2013.

NOTE 8 FAIR VALUE MEASUREMENTS

We record fair value at an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. We utilize a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

A summary of our investments as of June 30, 2013, classified as available for sale, and carried at fair value is as follows:

	As of June 30, 2013

Any future fluctuation in fair value related to these instruments that is judged to be temporary, including any recoveries of previous write-downs, will be recorded in Accumulated other comprehensive income or loss. If we determine that any future valuation adjustment was other-than-temporary, we will record a loss during the period such determination is made.

As of June 30, 2013, we have money market funds that qualify as cash equivalents, forward contracts for inventory purchases (Refer to Note 9) and contingent consideration related to the acquisitions of CURNA, Inc. (“CURNA”), Claros Diagnostics, Inc. (“OPKO Diagnostics”), FineTech Pharmaceuticals, Ltd. (“FineTech”), Farmadiet, and Cytochroma that are required to be measured at fair value on a recurring basis. In addition, in connection with our investment and our consulting agreement with Neovasc, we record the related Neovasc options and warrants at fair value as well as the derivative instruments related to our transactions with Pharmsynthez.

The estimated fair values of our financial instruments have been determined by using available market information and what we believe to be appropriate valuation methodologies. We use the following methods and assumptions in estimating fair value:

BZNE Notes and conversion feature - The stock market activity in BZNE does not represent an active market and as such, we determined the fair market value utilizing a business enterprise valuation approach in order to determine the fair value of our investment. The most significant assumptions are the projected revenue growth and operating income (loss). The impact of a change in any of our significant underlying assumptions +/-1% would not result in a materially different fair value.

Contingent consideration – We estimate the fair value of the contingent consideration utilizing a discounted cash flow model for the expected payments based on estimated timing and expected revenues. We use several discount rates depending on each type of contingent consideration related to FineTech, OPKO Diagnostics, CURNA, Farmadiet and Cytochroma transactions. The discount rates used range from 6% to 27% and were based on the weighted average cost of capital for those businesses. If the discount rates were to increase by 1%, on each transaction, the contingent consideration would decrease by $1.3 million. If estimated future sales were to decrease by 10%, the contingent consideration related to CURNA, FineTech and Cytochroma would decrease by $0.5 million. As of June 30, 2013, of the $68.9 million of contingent consideration, $5.3 million is recorded in Accrued expenses and $63.6 million is recorded in Other long-term liabilities. As of December 31, 2012, of the $20.0 million of contingent consideration, $5.1 million is recorded in Accrued expenses and $14.9 million is recorded in Other long-term liabilities.

Deferred payments – We estimate the fair value of the deferred payments utilizing a discounted cash flow model for the expected payments.

Embedded conversion option – We estimate the fair value of the embedded conversion option related to the Notes using a binomial lattice model. Refer to Note 6 for detail description of the binomial lattice model and the fair value assumptions used.

Pharmsynthez Note Receivable and Purchase Option - We determined the fair value of the Pharmsynthez Note Receivable and Purchase Option using a number of Black-Scholes scenarios simulating changes in Pharmsynthez's common stock price. Refer to Note 8.

NOTE 9 DERIVATIVE CONTRACTS

We enter into foreign currency forward exchange contracts to cover the risk of exposure to exchange rate differences arising from inventory purchases on letters of credit. Under these forward contracts, for any rate above or below the fixed rate, we receive or pay the difference between the spot rate and the fixed rate for the given amount at the settlement date.

The following table summarizes the fair values and the presentation of our derivative financial instruments in the Condensed Consolidated Balance Sheets:

To qualify the derivative instrument 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 June 30, 2013 and December 31, 2012, our derivative financial instruments do not meet the documentation requirements to be designated as hedges. Accordingly, we recognize the changes in fair value in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations.

NOTE 10 RELATED PARTY TRANSACTIONS

In January 2013, we entered into the Notes, with the Purchasers for the sale of $175.0 million aggregate principal amount of Notes in a private placement in reliance on exemptions from registration under the Securities Act. The Purchasers of the 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 Notes were issued on January 30, 2013.

In December 2012, we entered into a five-year lease agreement with AVI Properties, LLC (“AVI”), an entity affiliated with Dr. Jonathan Oppenheimer, OURLab’s Chief Executive Officer. The lease is for approximately 44,000 square feet of laboratory and office space in Nashville, Tennessee, where OURLab is based. The lease provides for payments of approximately $18 thousand per month in the first year, increasing annually if the consumer price index exceeds 5%, plus applicable sales tax. In addition to the rent, we pay a portion of operating expenses, property taxes and parking.

During the six months ended June 30, 2013, our FineTech subsidiary recorded revenue of $0.1 million for the sale of APIs to Teva Pharmaceutical Industries, Limited ("Teva"). Dr. Frost serves as the Chairman of the Board of Directors of Teva.

In February 2012, we entered into a cooperative research funding and option agreement with The Scripps Research Institute (“TSRI”) to support research for the development of novel oligomeric compounds relating to our molecular diagnostics technology (the “Research Agreement”). Pursuant to the Research Agreement, we agreed to provide funding of approximately $0.9 million annually over a five year period. In conjunction with entering into the Research Agreement, we also entered into a license agreement with TSRI for technology relating to libraries of peptide tertiary amides. In addition, we entered into a second license with TSRI for technology relating to highly selective inhibitors of c-Jun-N-Terminal Kinases that may be useful for the treatment of various diseases, including Parkinson’s disease. We also entered into a research funding and option agreement to provide funding of approximately $0.2 million annually over three years to support further development of the technology. Dr. Frost served as a Trustee for TSRI until November 2012 and Dr. Richard Lerner, a member of our Board of Directors, served as its President until December 2011.

In February 2012, we made a $1.0 million investment in ChromaDex. Other investors participating in the private financing included the Gamma Trust, Hsu Gamma, and Dr. Lerner. Following our investment, we own 1.5% of ChromaDex, the Gamma Trust owns approximately 16% of ChromaDex; Hsu Gamma owns approximately 1%; and certain of our directors own less than 1% of ChromaDex.

In February 2012, we purchased from BZNE $1.7 million of 10% secured convertible promissory notes (the “BZNE Notes”), convertible into BZNE common stock at a price equal to $0.20 per common share, which BZNE Notes are due and payable on February 24, 2014 and ten year warrants to purchase 8.5 million shares of BZNE common stock at an exercise price of $0.40 per share.

Mr. Roberto Prego Novo is the Chairman of BZNE and presently serves as a consultant to us. Dr. Frost and Mr. Prego Novo previously invested in BZNE in February and March, 2011. On May 16, 2011, BZNE acquired the assets and assumed the liabilities of Aero Pharmaceuticals, Inc. (“Aero”) in exchange for which BZNE issued an aggregate of 8,331,396 shares of its restricted common stock to Aero. On September 21, 2011, BZNE issued an additional 13,914 shares to Aero due to the late filing of a registration statement. Prior to the transaction, Dr. Frost, through the Gamma Trust, beneficially owned approximately 46% of Aero’s issued and outstanding capital stock; Mr. Prego Novo owned approximately 23% of Aero’s issued and outstanding capital stock through Olyrca Trust; and Dr. Hsiao beneficially owned approximately 12% of Aero’s issued and outstanding stock. Each of Drs. Frost and Hsiao and Mr. Prego Novo beneficially owned approximately 9.2%, 1.7%, and 8.2% of BZNE, respectively, following the purchase of Aero by BZNE. Mr. Rubin beneficially owns less than 1% of BZNE as a result of his prior ownership of Aero shares. In April 2012 and June 2012, Dr. Frost, through the Gamma Trust, also made loans to BZNE in the principal amounts of $0.3 million and $0.1 million, respectively, which were initially secured by a first priority lien on a particular BZNE receivable. The notes to Gamma Trust were subsequently amended and Gamma Trust no longer holds a security interest in the BZNE receivables.

In August 2011, we made an investment in Neovasc. Dr. Frost and other members of our management are shareholders of Neovasc. Prior to the investment, Dr. Frost beneficially owned approximately 36% of Neovasc, Dr. Hsiao owned approximately 6%, and Mr. Rubin owned less than 1%. Dr. Hsiao and Mr. Rubin also serve on the board of directors of Neovasc.

In November 2010, we made an investment in Fabrus. In exchange for the investment, we acquired approximately 13% of Fabrus on a fully diluted basis. Our investment was part of a $2.1 million financing for Fabrus. Other investors participating in the financing include the Gamma Trust and Hsu Gamma. In connection with the financing, Drs. Frost and Hsiao joined the Fabrus Board of Managers. Dr. Lerner owns approximately 5% of Fabrus. Mr. Vaughn Smider, Founder and CEO of Fabrus, is an Assistant Professor at TSRI. Dr. Frost served as a Trustee for TSRI until November 2012, and Dr. Lerner served as President of TSRI until December 2011.

In June 2010, we entered into a cooperative research and development agreement with Academia Sinica, Taipei, Taiwan (“Academia Sinica”), for pre-clinical work for a compound against various forms of cancer. Dr. Alice Yu, a member of our Board of Directors, is a Distinguished Research Fellow and Associate Director at the Genomics Research Center, Academia Sinica (“Genomics Research Center”). In connection with the Academia Sinica Agreement, we are required to pay Academia Sinica approximately $0.2 million over the term of the agreement.

Effective in September 2009, we entered into an agreement pursuant to which we invested $2.5 million in Cocrystal in exchange for 1,701,723 shares of Cocrystal’s Convertible Series A Preferred Stock. A group of investors, led by the Frost Group LLC, which is a trust controlled by Dr. Frost, Dr. Hsaio and Mr. Rubin, (the “Cocrystal Investors”), previously invested $5.0 million in Cocrystal, and agreed to invest an additional $5.0 million payable in two equal installments in September 2009 and March 2010. As a result of an amendment to the Cocrystal Investors’ agreements dated June 9, 2009, we, rather than the Cocrystal Investors, made the first installment investment ($2.5 million) on September 21, 2009.

In June 2009, we entered into a stock purchase agreement with Sorrento, pursuant to which we invested $2.3 million in Sorrento Therapeutics, Inc. ("Sorrento"). In exchange for the investment, we acquired approximately one-third of the outstanding common shares of Sorrento and received a fully-paid, exclusive license to the Sorrento antibody library for the discovery and development of therapeutic antibodies in the field of ophthalmology. On September 21, 2009, Sorrento entered into a merger transaction with Quikbyte Software, Inc. (“Quikbyte”). Prior to the merger transaction, certain investors, including Dr. Frost and other members of our management group, made an investment in Quikbyte. Dr. Lerner serves as a consultant and scientific advisory board member to Sorrento and owns less than one percent of its shares.

In November 2007, we entered into an office lease with Frost Real Estate Holdings, LLC (“Frost Holdings”), an entity affiliated with Dr. Frost. The lease is for approximately 8,300 square feet of space in an office building in Miami, Florida, where our principal executive offices are located. The lease provides for payments of approximately $18 thousand per month in the first year increasing annually to $24 thousand per month in the fifth year, plus applicable sales tax. The rent is inclusive of operating expenses, property taxes and parking. The rent for the first year was reduced to reflect a $30 thousand credit for the costs of tenant improvements. In August 2012, we entered into a six-month extension on the same terms as the 2007 expiring lease and in February 2013, we agreed to extend the lease on a month-to-month basis for up to an additional six months.

We reimburse Dr. Frost for Company-related use by Dr. Frost and our other executives of an airplane owned by a company that is beneficially owned by Dr. Frost. We reimburse Dr. Frost in an amount equal to the cost of a first class airline ticket between the travel cities for each executive, including Dr. Frost, traveling on the airplane for Company-related business. We do not reimburse Dr. Frost for personal use of the airplane by Dr. Frost or any other executive; nor do we pay for any other fixed or variable operating costs of the airplane. For the three and six months ended June 30, 2013, we reimbursed Dr. Frost approximately $5 thousand and $18 thousand, respectively, for Company-related travel by Dr. Frost and other OPKO

31

executives. For the three and six months ended June 30, 2012, we reimbursed Dr. Frost approximately $65 thousand and $129 thousand, respectively, for Company-related travel by Dr. Frost and other OPKO executives.

NOTE 11 COMMITMENTS AND CONTINGENCIES

In connection with our acquisitions of CURNA, OPKO Diagnostics, FineTech, Farmadiet, and Cytochroma, we agreed to pay future consideration to the sellers upon the achievement of certain events. As a result, as of June 30, 2013 , we recorded $68.9 million as contingent consideration, with $5.3 million recorded within Accrued expenses and $63.6 million recorded within Other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets. Refer to Note 4.

On April 29, 2013, we were named in a putative class action filed in the Eighth Judicial District Court in and for Clark County, Nevada against PROLOR Biotech, Inc. (“PROLOR”), the members of the PROLOR Board of Directors, individually (including Drs. Frost and Hsiao and Steven Rubin), and the Company. From May 1, 2013 through May 6, 2013, we were named in an additional five putative class actions suits filed in the Eighth Judicial District Court in and for Clark County, Nevada against the same defendants. On July 17, 2013, these suits were consolidated, for all purposes, into an amended class action complaint as part of the In re PROLOR Biotech, Inc. Shareholders' Litigation (Case No. A-13-680860-B). The lawsuit is brought by purported holders of PROLOR's common stock, both individually and on behalf of a putative class of PROLOR's stockholders, asserting claims that (i) PROLOR's directors breached their fiduciary duties in connection with the proposed merger by, among other things, purportedly failing to maximize stockholder value, (ii) PROLOR and its Board of Directors failed to disclose material information concerning the proposed merger, and (iii) the Company aided and abetted PROLOR's directors' alleged breach of their fiduciary duties. The lawsuit seeks various damages, an award of all costs, and reasonable attorneys' fees, as well as certain equitable relief, including enjoining consummation of the merger and, alternatively, rescinding the merger in the event it is consummated. The Company denies the allegations and intends to vigorously defend the actions. It is too early to assess the probability of a favorable or unfavorable outcome or the loss or range of loss, if any.

In November 2012, Adrian Goldstein, M.D., a former employee of OURLab, filed a complaint for declaratory judgment and alleged breach of contract against OURLab in the Chancery Court for Davidson County, Tennessee. Dr. Goldstein asserts in his complaint that OURLab breached his employment agreement and owes him additional compensation and further compensation for the value of OURLab under a “compensation for sale” provision set forth in his employment agreement. Dr. Goldstein seeks recovery of compensatory damages not to exceed $20 million, plus his attorney’s fees and litigation expenses. OURLab believes this action is without merit and is vigorously defending against plaintiff’s claims. It is too early to assess the probability of a favorable or unfavorable outcome or the loss or range of loss, if any.

In October 2012, we received a letter from counsel to Optos, Inc., making certain indemnity claims against us in connection with the sale of our ophthalmic instrumentation business. It is too early to assess the likelihood of litigation in this matter or the probability of a favorable or unfavorable outcome. However, we do not currently believe this matter will have a material impact on our results of operations or financial condition.

In July 2012, OURLab received a letter from AdvanceMed Corporation (“AdvanceMed”) regarding a post-payment review conducted by AdvanceMed (the “Post-Payment Review Letter”). The Post-Payment Review Letter originated with a post payment review audit by AdvanceMed of 183 claims submitted by OURLab to the Medicare program. OURLab believes that its billing practices were appropriate and it is following the appeal process set forth by Medicare. OURLab received a partially favorable determination, which reduced the amount of the alleged overpayment, and it continues to appeal the remaining alleged overpayments. No assurances can be given about the outcome of the appeal.

We are a party to other litigation in the ordinary course of business. We do not believe that any such litigation will have a material adverse effect on our business, financial condition, or results of operations.

We expect to incur substantial losses as we continue the development of our product candidates, continue our other research and development activities, and establish a sales and marketing infrastructure in anticipation of the commercialization of our diagnostic and pharmaceutical product candidates. We currently have limited commercialization capabilities, and it is possible that we may never successfully commercialize any of our diagnostic and pharmaceutical product candidates. We do not currently generate revenue from any of our diagnostic and pharmaceutical product candidates. Our research and development activities are budgeted to expand over a period of time and will require further resources if we are to be successful. As a result, we believe that our operating losses are likely to be substantial over the next several years. We may need to obtain additional funds to further develop our research and development programs, and there can be no assurance that additional capital will be available to us on acceptable terms, or at all.

NOTE 12 SEGMENTS

We currently manage our operations in two reportable segments, pharmaceuticals and diagnostics. The pharmaceuticals 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 and Brazil. The diagnostics segment consists of two operating segments, our (i) pathology operations we acquired through the acquisition of OURLab 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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

You should read this discussion together with the condensed consolidated financial statements, related Notes, and other financial information included elsewhere in this report and in our Annual Report on Form 10-K for the year ended December 31, 2012 (the “Form 10-K”). The following discussion contains assumptions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under “Risk Factors,” in Part II, Item 1A of our Form 10-K for the year ended December 31, 2012 as updated by our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013. These risks could cause our actual results to differ materially from those anticipated in these forward-looking statements.

We are a multi-national biopharmaceutical and diagnostics company that seeks to establish industry-leading positions in large and rapidly growing medical markets by leveraging our discovery, development and commercialization expertise and our novel and proprietary technologies. We are developing a range of solutions to diagnose, treat and prevent various conditions, including molecular diagnostics tests, laboratory developed tests (“LDTs”), point-of-care tests and proprietary pharmaceuticals and vaccines. We plan to commercialize these solutions on a global basis in large and high growth markets, including emerging markets.

We own established pharmaceutical platforms in Spain, Chile and Mexico, which are generating revenue and from which we expect to generate positive cash flow and facilitate future market entry for our products currently in development. We also recently established pharmaceutical operations in Brazil. We operate a specialty active pharmaceutical ingredients (“APIs”) manufacturer in Israel, which we expect will facilitate the development of our pipeline of molecules and compounds for our proprietary molecular diagnostic and therapeutic products. We operate a full-service medical laboratory specializing in urologic pathology with CLIA-certified laboratory facilities, that will provide us with a platform to commercialize certain of our novel diagnostics tests currently in development.

RECENT DEVELOPMENTS

In April 2013 we entered into an Agreement and Plan of Merger (the “PROLOR Merger Agreement”) pursuant to which we will acquire PROLOR Biotech, Inc. (“PROLOR”), a biopharmaceutical company focused on developing and commercializing longer-acting proprietary versions of already approved therapeutic proteins, in an all-stock transaction. Under the terms of the PROLOR Merger Agreement, holders of PROLOR common stock will receive 0.9951 shares of our Common Stock for each share of PROLOR common stock. Based on a price of $7.03 per share of our Common Stock, the transaction is valued at approximately $480 million, or $7.00 per share of PROLOR common stock. The companies expect the transaction to be completed during the second half of 2013. Closing of the transaction is subject to certain conditions including, the approval of PROLOR’s and our stockholders and other customary closing conditions. The Board of Directors of each of OPKO and PROLOR have approved the merger and the PROLOR Merger Agreement. In addition, the transaction was also approved by PROLOR’s Strategic Alternatives Committee.

In June 2013, PROLOR initiated a pivotal Phase III clinical trial for its long-acting version of human growth hormone, hGH-CTP, for treatment in adults with growth hormone deficiency (GHD). PROLOR has reported that previous trials showed that hGH-CTP has the potential to reduce the required dosing frequency of human growth hormone from the current standard of one injection per day to a single weekly injection. PROLOR has also stated that hGH-CTP demonstrated a good safety and tolerability profile in these previous clinical trials. A Phase II trial in children with GHD is currently ongoing. Recombinant human growth hormone (hGH) is used for the long-term treatment of children and adults with GHD due to inadequate secretion of endogenous growth hormone. hGH-CTP has been awarded orphan drug designation in the U.S. and Europe for both adults and children with GHD.

In April 2013, we entered into a series of concurrent transactions with OAO Pharmsynthez (“Pharmsynthez”), a Russian pharmaceutical company traded on the Moscow Stock Exchange. The transactions consisted of:

•We delivered approximately $9.6 million to Pharmsynthez at inception in exchange for approximately 13.6 million of its common shares.

•Pharmsynthez agreed to issue, at its option, approximately 12.0 million shares of its common stock or pay us Russian Rubles (“RUR”) 265.0 million ($8.1 million) on or before December 31, 2013.

•We have a right to purchase additional shares in Pharmsynthez at a fixed price if Pharmsynthez pays us in RUR rather than the 12.0 million shares of Pharmsynthez common stock (the “Purchase Option”).

•We delivered to Pharmsynthez a license agreement for certain technology rights in the Russian Federation, Ukraine, Belorussia, Azerbaidjan and Kazakhstan (the “Territories”). 

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

•Pharmsynthez will pay us $9.5 million under collaboration and funding agreements (the “Collaboration Payments”) for the development of the licensed technology rights (the “Collaboration Agreements”).  

We recorded the initial shares received in Pharmsynthez as an equity method investment.  We recorded the receivable of Pharmsynthez common stock or RUR, and the Purchase Option, as financial instruments and elected the fair value option for subsequent measurement. Changes in the fair value of the receivable from Pharmsynthez for its common stock or RUR, with the embedded derivative, and the Purchase Option are recorded in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2013

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 expense over the three-year term of the Collaboration Agreements.  We will record revenue in connection with the license agreement proportionately as the payments are received.  

RESULTS OF OPERATIONS

FOR THE THREE MONTHS ENDED JUNE 30, 2013 AND 2012

Revenues. Revenues for the three months ended June 30, 2013, were $23.8 million, compared to $10.2 million for the 2012 period. The increase in revenue principally reflected revenues related to the post June 30, 2012 acquisitions of Farmadiet Group Holding, S.L. (“Farmadiet”), SciVac Ltd ("SciVac"), previously known as SciGen (I.L.) Ltd, and Prost-Data, Inc. (“OURLab”), which contributed $5.2 million, $0.2 million and $2.9 million of revenue, respectively, during the three months

35

ended June 30, 2013. Revenue from our Chilean operations increased $1.3 million during the three months ended June 30, 2013, which was partially offset by a decrease of $0.2 million in revenue from our Mexican operations. Revenue from our Israeli API business increased $2.2 million during the three months ended June 30, 2013. Revenue related to our molecular diagnostics collaboration agreements and license agreements, increased $2.0 million during the three months ended June 30, 2013 compared to the 2012 period, primarily related to revenue recorded in connection to the Pharmsynthez's license agreement.

Costs of revenue. Costs of revenue for the three months ended June 30, 2013 was $13.1 million, compared to $6.6 million for the 2012 period. Costs of revenue for the three months ended June 30, 2013, increased principally due to costs of revenue recorded by Farmadiet, SciVac and OURLab of $1.8 million, $1.1 million and $2.9 million, respectively. Costs of revenue from our Israeli API business, as well as our Chilean and Mexican operations increased $0.2 million, $0.2 million and $0.3 million, respectively, during the three months ended June 30, 2013.

Selling, general and administrative expenses. Selling, general and administrative expenses for the three months ended June 30, 2013 were $13.9 million, compared to $5.4 million for the 2012 period. The increase in selling, general and administrative expenses principally resulted from $5.4 million of such expenses recorded during the three months ended June 30, 2013, by Farmadiet, SciVac, OURLab, Cytochroma Inc. ("Cytochroma") and OPKO Do Brasil Comércio De Produtos Farmacéuticos Ltda, previously known as Silcon Comércio, Importacao E Exportacao de Produtos Farmacéuticos e Cosmeticos Ltda ("OPKO Brazil"), which businesses were acquired post June 30, 2012. Excluding the selling, general and administrative expenses of the acquired businesses, selling, general and administrative expenses increased by $3.1 million during the three months ended June 30, 2013, principally as a result of increased personnel expenses and professional fees associated with our increased operations. Selling, general and administrative expenses during the three months ended June 30, 2013 and 2012, also include equity-based compensation expense of $1.2 million and $0.6 million, respectively.

Research and development expenses. Research and development expenses for the three months ended June 30, 2013 and 2012, were $9.6 million and $4.5 million, respectively. The increase in research and development expenses during the three months ended June 30, 2013, principally resulted from an increase of $4.0 million related to the Cytochroma development programs, including the cost of the ongoing Phase 3 clinical trials for RayaldyTM and from $0.4 million related to research and development activities performed by Farmadiet. During the three months ended June 30, 2013, we recorded, as an offset to research and development expenses, $0.5 million related to research and development grants received and our collaboration and funding arrangements. Research and development expenses for the three months ended June 30, 2013 and 2012, also included equity-based compensation expense of $0.5 million and $0.4 million, respectively.

Contingent consideration. Contingent consideration expenses for the three months ended June 30, 2013 and 2012, were $2.6 million and $1.0 million, respectively. The increase in contingent consideration expense resulted from changes in the fair value of the contingent consideration liabilities due to the time value of money and the impact of changes in the underlying assumptions, if any, during the period. The contingent consideration liabilities relate to potential amounts payable to former stockholders of CURNA, Inc. ("CURNA"), Claros Diagnostics Inc. (“OPKO Diagnostics”), FineTech Pharmaceuticals, Ltd. ("FineTech"), Farmadiet and Cytochroma pursuant to our acquisition agreements in January 2011, October 2011, December 2011, August 2012 and March 2013, respectively.

Amortization of intangible assets. Amortization of intangible assets was $2.7 million and $2.1 million for the three months ended June 30, 2013 and 2012, respectively. Amortization expense increased due to the acquisitions of Farmadiet, OURLab and Cytochroma, in August 2012, December 2012 and March 2013, respectively.

Other income and (expense), net. Other income and (expense), net for the three months ended June 30, 2013 and 2012 was $16.9 million and ($0.4) million, respectively. During the three months ended June 30, 2013, we recorded a $9.9 million non-cash other income expense related to the changes in the fair value of the embedded derivatives in the 3.00% convertible senior notes, (the "Notes"), a $2.6 million non-cash other income related to the changes in the fair value of Pharmsynthez Note Receivable and Purchase Option, and a gain of $6.3 million on the sale of certain of our investments available for sale. Other income and (expense), net, for the three months ended June 30, 2013, also included $3.8 million of interest expense principally related to interest expense incurred by the Notes and by the amortization of related deferred financing costs. For the three months ended June 30, 2012, other expense, net principally consisted of interest expense incurred in our Chilean lines of credit and foreign currency expense, partially offset by the interest earned on our cash and cash equivalents.

Loss from investment in investees. Loss from investment in investees was $2.4 million and $0.5 million for the three months ended June 30, 2013 and 2012, respectively. The increase in loss from investment in investees is primarily due to the result of increased research and development activities at our investees as well as the impact of including the activities of our recent investment in RXi Pharmaceuticals Corporation ("RXi") and Pharmsynthez.

36

Income taxes. Our income tax provision reflects the projected income tax payable in Israel, Chile, Spain and Canada. We have recorded a full valuation allowance against our deferred tax assets in the U.S. In May 2013, our Israeli API business elected a new tax regime, which sets its effective tax rate at 12.5% compared to a previous tax rate that was based on a ratio of revenue and turnover basis in the old tax regime, ranging from 10% to 25%.

FOR THE SIX MONTHS ENDED JUNE 30, 2013 AND 2012

Revenues. Revenues for the six months ended June 30, 2013, were $55.2 million, compared to $19.0 million for the 2012 period. The increase in revenue principally reflected one-time, non–cash revenue of $12.5 million related to the sale of substantially all of our assets in the field of RNA interference to RXi, and revenues related to the post June 30, 2012, acquisitions of Farmadiet, SciVac and OURLab, which contributed $9.5 million, $0.9 million and $5.8 million of revenue, respectively, during the six months ended June 30, 2013. Revenue from our Chilean operations increased $3.3 million during the six months ended June 30, 2013, which was partially offset by a decrease of $0.6 million in revenue from our Mexican operations. Revenue from our Israeli API business increased $2.5 million during the six months ended June 30, 2013. Revenue related to our molecular diagnostics collaboration agreements and license agreements, excluding the RXi revenue, increased $2.3 million during the six months ended June 30, 2013 compared to the 2012 period, primarily related to revenue recorded in connection to the Pharmsynthez's license agreement.

Cost of revenue. Costs of revenue for the six months ended June 30, 2013 was $24.9 million, compared to $11.5 million for the 2012 period. Costs of revenue for the six months ended June 30, 2013 increased principally as a result of costs of revenues related to the post June 30, 2012 acquisitions of Farmadiet, SciVac and OURLab of $3.5 million, $1.9 million, and $5.6 million, respectively. Costs of revenue from our Israeli API business, our Chilean and Mexican operations increased $0.2 million, $1.7 million and $0.4 million, respectively, during the six months ended June 30, 2013.

Selling, general and administrative expenses. Selling, general and administrative expenses for the six months ended June 30, 2013, were $26.3 million, compared to $10.1 million for the 2012 period. The increase in selling, general and administrative expenses principally resulted from $9.9 million of such expenses recorded during the six months ended June 30, 2013, by Farmadiet, SciVac, OURLab, Cytochroma and OPKO Brazil, which businesses were acquired post June 30, 2012. Excluding the selling, general and administrative expenses of the acquired businesses, selling, general and administrative expenses increased by $6.3 million during the six months ended June 30, 2013, principally as a result of increased personnel expenses and professional fees associated with our increased operations. Selling, general and administrative expenses during the six months ended June 30, 2013 and 2012, also include equity-based compensation expense of $2.6 million and $1.2 million, respectively.

Research and development expenses. Research and development expenses for the six months ended June 30, 2013 and 2012, were $19.5 million and $9.3 million, respectively. The increase in research and development expenses during the six months ended June 30, 2013, principally resulted from an increase of $5.7 million related to the Cytochroma development programs, including the cost of the ongoing Phase 3 clinical trials for Rayaldy^TM, and from $0.7 million related to research and development activities performed by Farmadiet. Research and development expenses for the six months ended June 30, 2013 and 2012, also include equity-based compensation expense of $4.4 million and $1.0 million, respectively. The increase in equity-based compensation expense principally reflects the mark to market impact of Common Stock options granted to non-employees and the associated increase in the trading price of our Common Stock during the six months ended June 30, 2013. During the six months ended June 30, 2013, we recorded, as an offset to research and development expenses, $1.0 million related to grants and collaboration and funding arrangements.

Contingent consideration. Contingent consideration expenses for the six months ended June 30, 2013 and 2012, were $3.9 million and $2.1 million, respectively. The increase in contingent consideration expense resulted from changes in the fair value of the contingent consideration liabilities due to the time value of money and the impact of changes in the underlying assumptions, if any, during the period. The contingent consideration liabilities relate to potential amounts payable to former stockholders of CURNA, OPKO Diagnostics, FineTech, Farmadiet and Cytochroma pursuant to our acquisition agreements in January 2011, October 2011, December 2011, August 2012 and March 2013, respectively.

Amortization of intangible assets. Amortization of intangible assets was $5.4 million and $4.1 million for the six months ended June 30, 2013 and 2012, respectively. Amortization expense increased due to the acquisitions of Farmadiet, OURLab and Cytochroma in August 2012, December 2012 and March 2013, respectively.

Other income and (expense), net. Other income and (expense), net for the six months ended June 30, 2013 and 2012, was ($7.1) million and $0.5 million, respectively. During the six months ended June 30, 2013, we recorded a $14.9 million non-cash charge, net, related to the changes in the fair value of the embedded derivatives in the Notes, partially offset by other income of $1.2 million related to changes in the fair value of the warrants and options received in connection with our investment in Neovasc and by other income of $2.6 million related to the changes in the fair value of Pharmsynthez Note Receivable and

37

Purchase Option. Other income and (expense), net, for the six months ended June 30, 2013, also included $6.7 million of interest expense primarily related to interest expense incurred by the Notes and by the amortization of related deferred financing costs. For the six months ended June 30, 2012, other income, net included $1.1 million of other income recognized from the change in fair value of the warrants received in connection with our investment in Biozone Pharmaceuticals, Inc., partially offset by other expense recognized for the decrease in fair value of warrants and options received in connections with our investment in Neovasc and the interest expense incurred by our Chilean lines of credit.

Loss from investment in investees. Loss from investment in investees was $6.3 million and $1.0 million for the six months ended June 30, 2013 and 2012, respectively. The increase in loss from investment in investees is primarily due to the result of increased research and development activities at our investees as well as the impact of including the activities of RXi and Pharmsynthez for the six months ended June 30, 2013.

Income taxes. Our income tax provision reflects the projected income tax payable in Israel, Chile, Spain and Canada. We have recorded a full valuation allowance against our deferred tax assets in the U.S. On May 2013, our Israeli API business elected a new tax regime, which sets its effective tax rate at 12.5% compared to a previous tax rate that was based on a ratio of revenue and turnover basis in the old tax regime, ranging from 10% to 25%.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2013, we had cash, cash equivalents and marketable securities of approximately $169.1 million. Cash used in operations during 2013 principally reflects expenses related to selling, general and administrative activities related to our corporate operations, research and development activities and our operations in Chile, Spain, SciVac, Brazil and Mexico, partially offset by cash provided from our operations at FineTech. Cash used in investing activities primarily reflects the purchase of marketable securities of $50.0 million, the $13.3 million investment in RXi and Pharmsynthez, capital expenditures of $2.1 million and net cash used in business combinations of $0.1 million, partially offset from the sale of investments available for sale. Cash provided by financing activities primarily reflects the issuance of the Notes and $1.5 million received from Common Stock option and Common Stock warrant exercises. Since our inception, we have not generated sufficient gross margins to offset our operating and other expenses and our primary source of cash has been from the public and private placement of stock and credit facilities available to us.

In April 2013 we invested $9.6 million in exchange for approximately 13.6 million shares of Pharmsynthez common stock. Concurrent with out investment, Pharmsynthez also agreed to issue, at its option, approximately 12.0 million shares of its common stock or pay us Russian Rubles (“RUR”) 265.0 million ($8.1 million) on or before December 31, 2013. We have a right to purchase additional shares in Pharmsynthez at a fixed price if Pharmsynthez pays us in RUR rather than the 12.0 million shares of Pharmsynthez common stock (the “Purchase Option”).

In January 2013, we issued $175.0 million of Notes. The Notes were sold in a private placement in reliance on exemptions from registration under the Securities Act. A $4.5 million discount was granted to the placement agent and an additional $0.4 million in deferred charges were recorded for professional fees related to the issuance. Net cash proceeds from the offering totaled $170.2 million. Interest on the Notes is payable semiannually on February 1 and August 1, beginning August 1, 2013. Holders of the Notes may require us to repurchase the Notes for 100% of their principal amount, plus accrued and unpaid interest, on February 1, 2019, February 1, 2023 and February 1, 2028, or following the occurrence of a fundamental change as defined in the indenture governing the Notes.

In connection with our acquisitions of CURNA, OPKO Diagnostics, FineTech and Cytochroma we agreed to pay future consideration to the sellers upon the achievement of certain events, including minimum cash payments of $5.0 million to the former stockholder of FineTech upon the achievement of certain sales milestones, of which $2.7 million was paid in March 2013; up to an additional $19.1 million in shares of our Common Stock to the former stockholders of OPKO Diagnostics upon and subject to the achievement of certain milestones; and up to an additional $190.0 million in either shares of our Common Stock or cash, at our option subject to the achievement of certain milestones, to the former shareholders of Cytochroma. In connection with the acquisition of Farmadiet, we agreed to pay an additional €3.4 million (US$4.3 million) in August 2013 and €3.4 million (US$4.3 million) in February 2014 in cash or shares of our Common Stock. On August 2, 2013, we issued 585,703 shares of our Common Stock to satisfy the August 2013 obligation. Further, upon the achievement of certain development milestones, we are obligated to issue 125,000 shares of our Common Stock and €0.8 million (US$1.0 million) in shares of our Common Stock or cash, at our option.

As of June 30, 2013, we have outstanding lines of credit in the aggregate amount of $13.3 million with 15 financial institutions in Chile and Spain, of which $6.4 million is unused. The weighted average interest rate on these lines of credit is approximately 6.4%. These lines of credit are short-term and are generally due within three months. These lines of credit are used primarily as a source of working capital for inventory purchases. The highest balance at any time during the six months ended June 30, 2013, was $16.5 million. We intend to continue to enter into these lines of credit as needed. There is no assurance that these lines of credit or other funding sources will be available to us on acceptable terms, or at all, in the future.

We expect to incur losses from operations for the foreseeable future. We expect to incur substantial research and development expenses, including expenses related to the hiring of personnel and additional clinical trials. We expect that selling, general and administrative expenses will also increase as we expand our sales, marketing and administrative staff and add infrastructure.

We believe that the cash, cash equivalents, and marketable securities on hand at June 30, 2013, which include the net proceeds from the Notes, and the amounts available to be borrowed under our lines of credit are sufficient to meet our anticipated cash requirements for operations and debt service beyond the next 12 months. We based this estimate on assumptions that may prove to be wrong or are subject to change, and we may be required to use our available cash resources sooner than we currently expect. If we acquire additional assets or companies, accelerate our product development programs or initiate additional clinical trials, we will need additional funds. Our future cash requirements will depend on a number of factors, including possible acquisitions, the continued progress of research and development of our product candidates, the timing and outcome of clinical trials and regulatory approvals, the costs involved in preparing, filing, prosecuting, maintaining,

39

defending, and enforcing patent claims and other intellectual property rights, the status of competitive products, the availability of financing, and our success in developing markets for our product candidates. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of, or eliminate one or more of our clinical trials or research and development programs or possible acquisitions.

The following table provides information as of June 30, 2013 with respect to the amounts and timing of our known contractual obligation payments due by period.

Contractual obligations (In thousands)	Remaining Six Months ending December 31,  2013		2014		2015		2016		2017		2018		Thereafter		Total

(1) Excludes $1.3 million of consolidated liabilities related to SciVac, as to which there is no recourse against us.

The preceding table does not include information where the amounts of the obligations are not currently determinable, including the following:

- Contractual obligations in connection with clinical trials, which span over two years, and that depend on patient enrollment. The total amount of expenditures is dependent on the actual number of patients enrolled and as such, the contracts do not specify the maximum amount we may owe.

- Product license agreements effective during the lesser of 15 years or patent expiration whereby payments and amounts are determined by applying a royalty rate on uncapped future sales.

- Contingent consideration that includes payments upon achievement of certain milestones including meeting development milestones such as the completion of successful clinical trials, new drug application approvals by the U.S. FDA and revenue milestones upon the achievement of certain revenue targets all of which are anticipated to be paid within the next 7 years and are payable in either shares of our Common Stock or cash, at our option, and that may aggregate up to $213.3 million.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Accounting estimates. The preparation of financial statements in conformity with generally accepted accounting principles 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 sales and expenses during the reporting period. Actual results could differ from those estimates.

Equity-based compensation. We recognize equity based compensation as an expense in our financial statements and that cost is measured at the fair value of the awards and expensed over their vesting period. Equity-based compensation arrangements to non-employees are recorded at their fair value on the measurement date. We estimate the grant-date fair value of our stock option grants using a valuation model known as the Black-Scholes-Merton formula or the “Black-Scholes Model” and allocate the resulting compensation expense over the corresponding requisite service period associated with each grant. The Black-Scholes Model requires the use of several variables to estimate the grant-date fair value of stock options including expected term, expected volatility, expected dividends and risk-free interest rate. We perform significant analyses to calculate and select the appropriate variable assumptions used in the Black-Scholes Model. We also perform significant analyses to estimate forfeitures of equity-based awards. We are required to adjust our forfeiture estimates on at least an annual basis based on the number of share-based awards that ultimately vest. The selection of assumptions and estimated forfeiture rates is subject to significant judgment and future changes to our assumptions and estimates may have a material impact on our Condensed Consolidated Financial Statements.

40

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 and other intangible assets acquired in business combinations, licensing and other transactions were $364.9 million million and $176.2 million, respectively, at June 30, 2013 and December 31, 2012, representing approximately 57% and 61% of total assets, respectively.

Assets acquired and liabilities assumed in business combinations, licensing and other transactions are recognized at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recognized as goodwill. We determined the fair value of intangible assets, including in-process research and development (“IPR&D”), using the “income method.” This method starts with a forecast of net cash flows, risk adjusted for estimated probabilities of technical and regulatory success (for IPR&D) and adjusted to present value using an appropriate discount rate that reflects the risk associated with the cash flow streams. All assets are valued from a market participant view which might be different than our specific views. The valuation process is very complex and requires significant input and judgment using internal and external sources. Although the valuations are required to be finalized within a one-year period, it must consider all and only those facts and evidence available at the acquisition date. The most complex and judgmental matters applicable to the valuation process are summarized below:

• Unit of account – Most intangible assets are valued as single global assets rather than multiple assets for each jurisdiction or indication after considering the development stage, expected levels of incremental costs to obtain additional approvals, risks associated with further development, amount and timing of benefits expected to be derived in the future, expected patent lives in various jurisdictions and the intention to promote the asset as a global brand.

• Estimated useful life – The asset life expected to contribute meaningful cash flows is determined after considering all pertinent matters associated with the asset, including expected regulatory approval dates (if unapproved), exclusivity periods and other legal, regulatory or contractual provisions as well as the effects of any obsolescence, demand, competition, and other economic factors, including barriers to entry.

• Probability of Technical and Regulatory Success (“PTRS”) Rate – PTRS rates are determined based upon industry averages considering the respective programs development stage and disease indication and adjusted for specific information or data known at the acquisition date. Subsequent clinical results or other internal or external data obtained could alter the PTRS rate and materially impact the estimated fair value of the intangible asset in subsequent periods leading to impairment charges.

• Projections – Future revenues are estimated after considering many factors such as initial market opportunity, pricing, sales trajectories to peak sales levels, competitive environment and product evolution. Future costs and expenses are estimated after considering historical market trends, market participant synergies and the timing and level of additional development costs to obtain the initial or additional regulatory approvals, maintain or further enhance the product. We generally assume initial positive cash flows to commence shortly after the receipt of expected regulatory approvals which typically may not occur for a number of years. Actual cash flows attributed to the project are likely to be different than those assumed since projections are subjected to multiple factors including trial results and regulatory matters which could materially change the ultimate commercial success of the asset as well as significantly alter the costs to develop the respective asset into commercially viable products.

• Tax rates – The expected future income is tax effected using a market participant tax rate. Our recent valuations typically use a U.S. tax rate (and applicable state taxes) after considering the jurisdiction in which the intellectual property is held and location of research and manufacturing infrastructure. We also considered that any earnings repatriation would likely have U.S. tax consequences.

• Discount rate – Discount rates are selected after considering the risks inherent in the future cash flows; the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry, as well as expected changes in standards of practice for indications addressed by the asset.

Goodwill was $82.1 million and $80.5 million, respectively, at June 30, 2013 and December 31, 2012. Goodwill is tested at least annually for impairment or when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, on an enterprise level by assessing qualitative factors or performing a quantitative analysis in determining whether it is more likely than not that its fair value exceeds the carrying value. Examples of qualitative factors include our share price, our financial performance compared to budgets, long-term financial plans, macroeconomic, industry

41

and market conditions as well as the substantial excess of fair value over the carrying value of net assets from the annual impairment test performed in the prior year.

Intangible assets were $282.8 million and $95.8 million, including IPR&D of $203.1 million and $11.5 million, respectively, at June 30, 2013 and December 31, 2012. Intangible assets are tested for impairment whenever events or changes in circumstances warrant a review, although IPRD is required to be tested at least annually. Intangible assets are highly vulnerable to impairment charges, particularly newly acquired assets for recently launched products or IPR&D. These assets are initially measured at fair value and therefore any reduction in expectations used in the valuations could potentially lead to impairment. Some of the more common potential risks leading to impairment include competition, earlier than expected loss of exclusivity, pricing pressures, adverse regulatory changes or clinical trial results, delay or failure to obtain regulatory approval and additional development costs, inability to achieve expected synergies, higher operating costs, changes in tax laws and other macro-economic changes. The complexity in estimating the fair value of intangible assets in connection with an impairment test is similar to the initial valuation.

Considering the high risk nature of research and development and the industry’s success rate of bringing developmental compounds to market, IPR&D impairment charges are likely to occur in future periods. IPR&D is closely monitored and assessed each period for impairment.

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.

Allowance for doubtful accounts and 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 are based upon the historical patterns of products returned 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 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.

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 management’s estimate of the collectability of accounts receivable. The allowance for doubtful accounts recognized in our Condensed Consolidated Balance Sheets at June 30, 2013 and December 31, 2012 was $0.9 million and $0.5 million, respectively.

Recent accounting pronouncements. In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, (“ASU 2013-02”). ASU 2013-02 requires the presentation of reclassifications out of accumulated other comprehensive income in either (1) the notes or (2) the face of the financial statements. We adopted ASU 2013-02 for our first quarter ended March 31, 2013. The adoption of ASU 2013-02 did not have a material impact in our condensed consolidated financial statements, but did require certain additional disclosures.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In the normal course of doing business, we are exposed to the risks associated with foreign currency exchange rates and changes in interest rates.

Foreign Currency Exchange Rate Risk – Although we do not speculate in the foreign exchange market, we may from time to time manage exposures that arise in the normal course of business related to fluctuations in foreign currency exchange rates by entering into offsetting positions through the use of foreign exchange forward contracts. Certain firmly committed transactions are hedged with foreign exchange forward contracts. As exchange rates change, gains and losses on the exposed

42

transactions are partially offset by gains and losses related to the hedging contracts. Both the exposed transactions and the hedging contracts are translated at current spot rates, with gains and losses included in earnings.

Our derivative activities, which consist of foreign exchange forward contracts, are initiated to hedge forecasted cash flows that are exposed to foreign currency risk. The foreign exchange forward contracts generally require us to exchange local currencies for foreign currencies based on pre-established exchange rates at the contracts’ maturity dates. As exchange rates change, gains and losses on these contracts are generated based on the change in the exchange rates that are recognized in the Consolidated Statement of Operations at maturity, and offset the impact of the change in exchange rates on the foreign currency cash flows that are hedged. If the counterparties to the exchange contracts do not fulfill their obligations to deliver the contracted currencies, we could be at risk for currency related fluctuations. We had $2.2 million in foreign exchange forward contracts outstanding at June 30, 2013, primarily to hedge Chilean-based operating cash flows against U.S. dollars. If Chilean Pesos were to strengthen in relation to the U.S. dollar, our loss or gain on hedged foreign currency cash-flows would be offset by the derivative contracts, with a net effect of zero.

We do not engage in trading market risk sensitive instruments or purchasing hedging instruments or “other than trading” instruments that are likely to expose us to significant market risk, whether interest rate, foreign currency exchange, commodity price, or equity price risk.

Interest Rate Risk – Our exposure to market risk relates to our cash and investments and to our borrowings. We maintain an investment portfolio of money market funds. The securities in our investment portfolio are not leveraged, and are, due to their very short-term nature, subject to minimal interest rate risk. We currently do not hedge interest rate exposure. Because of the short-term maturities of our investments, we do not believe that a change in market interest rates would have a significant negative impact on the value of our investment portfolio except for reduced income in a low interest rate environment.

At June 30, 2013, we had cash and cash equivalents and marketable securities of $169.1 million. The weighted average interest rate related to our cash and cash equivalents for the six months ended June 30, 2013 was 0%. As of June 30, 2013, the principal value of our credit lines was $13.3 million at a weighted average interest rate of approximately 6.4% for the six months then ended. In addition, we have outstanding 3.00% convertible senior notes with a face value of $175 million.

The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we invest our excess cash in debt instruments of the U.S. Government and its agencies, bank obligations, repurchase agreements and high-quality corporate issuers, and money market funds that invest in such debt instruments, and, by policy, restrict our exposure to any single corporate issuer by imposing concentration limits. To minimize the exposure due to adverse shifts in interest rates, we maintain investments at an average maturity of generally less than three months.

Item 4. Controls and Procedures

The Company’s management, under the supervision and with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), has evaluated the effectiveness of the Company’s disclosure controls and procedures as defined in Securities and Exchange Commission (“SEC”) Rule 13a-15(e) as of June 30, 2013. Based on that evaluation, the CEO and CFO have concluded that the Company’s disclosure controls and procedures are effective to ensure that information the Company is required to disclose in reports that it files or submits under the Securities Exchange Act is accumulated and communicated to management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

Changes to the Company’s Internal Control Over Financial Reporting

In connection with the Farmadiet Group Holding, S.L. ("Farmadiet"), SciVac Ltd, formerly SciGen (I.L.) Ltd ("SciVac"), OPKO OURLab LLC, formerly Prost-Data, Inc. ("OURLab") and Cytochroma Inc. ("Cytochroma") acquisitions in August 2012, October 2012, December 2012 and March 2013, respectively, we began implementing standards and procedures at Farmadiet, SciVac, OURLab and Cytochroma, including upgrading and establishing controls over accounting systems, and adding employees and consultants who are trained and experienced in the preparation of financial statements in accordance with U.S. GAAP to ensure that we have in place appropriate internal control over financial reporting at Farmadiet, SciVac, OURLab and Cytochroma. These changes to the Company’s internal control over financial reporting that occurred during the Company’s second fiscal quarter of 2013 have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

On April 29, 2013, a putative class action was filed in the Eighth Judicial District Court in and for Clark County, Nevada against PROLOR Biotech, Inc. (“PROLOR”), the members of the PROLOR Board of Directors, individually (including Drs. Frost and Hsiao and Steven Rubin), and the Company. From May 1, 2013 through May 6, 2013, we were named in an additional five putative class actions lawsuits filed in the Eight Judicial District Court in and for Clark County, Nevada against the same defendants. On July 17, 2013, these six suits were consolidated, for all purposes, into an amended class action complaint as part of the In re PROLOR Biotech, Inc. Shareholders' Litigation (Case No. A-13-680860-B). The lawsuit is brought by purported holders of PROLOR's common stock, both individually and on behalf of a putative class of PROLOR's stockholders, asserting claims that (i) PROLOR's directors breached their fiduciary duties in connection with the proposed merger by, among other things, purportedly failing to maximize stockholder value, (ii) PROLOR and its Board of Directors failed to disclose material information concerning the proposed merger, and (iii) the Company aided and abetted PROLOR's directors' alleged breach of their fiduciary duties. The lawsuit seeks various damages, an award of all costs, and reasonable attorneys' fees, as well as certain equitable relief, including enjoining consummation of the merger and, alternatively, rescinding the merger in the event it is consummated. The Company denies the allegations and intends to vigorously defend the actions. It is too early to assess the probability of a favorable or unfavorable outcome or the loss or range of loss, if any.

Item 1A. Risk Factors

There have been no material changes in our risk factors from those disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, as updated by the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2013.

Fair Value Measurements

6 Months Ended

Jun. 30, 2013

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

We record fair value at an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. We utilize a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

A summary of our investments as of June 30, 2013, classified as available for sale, and carried at fair value is as follows:

	As of June 30, 2013
(In thousands)	Amortized Cost		Gross unrealized gains in Accumulated OCI		Gross unrealized losses in Accumulated OCI			Gain/(Loss) in Accumulated Deficit			Fair value
Common stock investments, available for sale	$	1,376	$	1,160	$	—		$	—		$	2,536
BZNE Note and conversion feature	1,700		53		—			287			2,040

Total assets	$	79,041	$	1,928	$	(7	)	$	959		$	81,921

A summary of our investments as of December 31, 2012, classified as available for sale, and carried at fair value is as follows:

	As of December 31, 2012
(In thousands)	Amortized Cost		Gross unrealized gains in Accumulated OCI		Gross unrealized losses in Accumulated OCI		Gain/(Loss) in Accumulated Deficit			Fair value
Common stock investments, available for sale	$	2,051	$	6,185	$	—	$	—		$	8,236

Total assets	$	5,335	$	6,725	$	—	$	88		$	12,148

Any future fluctuation in fair value related to these instruments that is judged to be temporary, including any recoveries of previous write-downs, will be recorded in Accumulated other comprehensive income or loss. If we determine that any future valuation adjustment was other-than-temporary, we will record a loss during the period such determination is made.

As of June 30, 2013, we have money market funds that qualify as cash equivalents, forward contracts for inventory purchases (Refer to Note 9) and contingent consideration related to the acquisitions of CURNA, Inc. (“CURNA”), Claros Diagnostics, Inc. (“OPKO Diagnostics”), FineTech Pharmaceuticals, Ltd. (“FineTech”), Farmadiet, and Cytochroma that are required to be measured at fair value on a recurring basis. In addition, in connection with our investment and our consulting agreement with Neovasc, we record the related Neovasc options and warrants at fair value as well as the derivative instruments related to our transactions with Pharmsynthez.

Our financial assets and liabilities measured at fair value on a recurring basis are as follows:

Our U.S. Treasury securities mature on September 5, 2013 ($25.0 million), September 30, 2013 ($25.0 million) and October 15, 2013 ($25.0 million).

The carrying amount and estimated fair value of our long-term debt, as well as the applicable fair value hierarchy tiers, are contained in the table below. The fair value of the Notes is determined using a binomial lattice approach in order to estimate the fair value of the embedded derivative in the Notes. Refer to Note 6.

The estimated fair values of our financial instruments have been determined by using available market information and what we believe to be appropriate valuation methodologies. We use the following methods and assumptions in estimating fair value:

BZNE Notes and conversion feature - The stock market activity in BZNE does not represent an active market and as such, we determined the fair market value utilizing a business enterprise valuation approach in order to determine the fair value of our investment. The most significant assumptions are the projected revenue growth and operating income (loss). The impact of a change in any of our significant underlying assumptions +/-1% would not result in a materially different fair value.

Contingent consideration – We estimate the fair value of the contingent consideration utilizing a discounted cash flow model for the expected payments based on estimated timing and expected revenues. We use several discount rates depending on each type of contingent consideration related to FineTech, OPKO Diagnostics, CURNA, Farmadiet and Cytochroma transactions. The discount rates used range from 6% to 27% and were based on the weighted average cost of capital for those businesses. If the discount rates were to increase by 1%, on each transaction, the contingent consideration would decrease by $1.3 million. If estimated future sales were to decrease by 10%, the contingent consideration related to CURNA, FineTech and Cytochroma would decrease by $0.5 million. As of June 30, 2013, of the $68.9 million of contingent consideration, $5.3 million is recorded in Accrued expenses and $63.6 million is recorded in Other long-term liabilities. As of December 31, 2012, of the $20.0 million of contingent consideration, $5.1 million is recorded in Accrued expenses and $14.9 million is recorded in Other long-term liabilities.

Deferred payments – We estimate the fair value of the deferred payments utilizing a discounted cash flow model for the expected payments.

Embedded conversion option – We estimate the fair value of the embedded conversion option related to the Notes using a binomial lattice model. Refer to Note 6 for detail description of the binomial lattice model and the fair value assumptions used.

Pharmsynthez Note Receivable and Purchase Option - We determined the fair value of the Pharmsynthez Note Receivable and Purchase Option using a number of Black-Scholes scenarios simulating changes in Pharmsynthez's common stock price. Refer to Note 8.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2013

Accounting Policies [Abstract]

Basis of presentation

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 and six months ended June 30, 2013, are not necessarily indicative of the results of operations and cash flows that may be reported for the remainder of 2013 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, 2012.

Reclassifications

Reclassifications. Certain prior year amounts in the condensed consolidated financial statements have been reclassified to conform with the 2013 presentation. Due to the acquisition of OPKO OURLab, LLC (formerly Prost-Data, Inc.), our CLIA-certified laboratory business (“OURLab”) in December 2012, we changed our segment presentation to include diagnostics as a reportable segment. As a result of this change in reportable segments, we restated certain prior year amounts in the condensed consolidated financial statements to conform with the 2013 presentation. These reclassifications had no impact on our results of operations.

Principles of consolidation

Principles of consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of OPKO Health, Inc., 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

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. 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. 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 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. Goodwill and other intangible assets acquired in business combinations, licensing and other transactions at June 30, 2013 and December 31, 2012 were $364.9 million and $176.2 million, respectively.

Assets acquired and liabilities assumed in business combinations, licensing and other transactions are recognized at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recognized as goodwill. We determined the fair value of intangible assets, including in-process research and development (“IPR&D”), using the “income method.”

Goodwill is tested at least annually for impairment, or when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, on an enterprise level by assessing qualitative factors or performing a quantitative analysis in determining whether it is more likely than not that its fair value exceeds the carrying value.

Fair value measurements

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 June 30, 2013 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.

In evaluating the fair value information, considerable judgment is required to interpret the market data used to develop the estimates. The use of different market assumptions and/or different valuation techniques may have a material effect on the estimated fair value amounts. Accordingly, the estimates of fair value presented herein may not be indicative of the amounts that could be realized in a current market exchange.

Contingent consideration

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

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 June 30, 2013 and December 31, 2012, 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 in Fair value changes of derivatives instruments, net, in our Condensed Consolidated Statement of Operations.

Revenue recognition

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 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 and six months ended June 30, 2013, revenue from services also includes $0.2 million and $0.4 million, respectively, of revenue related to our consulting agreement with Neovasc, Inc. (“Neovasc”) and to revenue related to molecular diagnostics collaboration agreements. For the three and six months ended June 30, 2012, revenue from services included $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.

Revenue from transfer of intellectual property includes revenue related to the sale, license or transfer of intellectual property such as upfront license payments, license fees and milestone payments received through our license, collaboration and commercialization agreements. We analyze our multiple-element arrangements to determine whether the elements can be separated and accounted for individually as separate units of accounting.

Non-refundable license fees for the out-license of our technology are recognized depending on the provisions of each agreement. We recognize non-refundable upfront license payments as revenue upon receipt if the license has standalone value and the fair value of our undelivered obligations, if any, can be determined. If the license is considered to have standalone value but the fair value of any of the undelivered items cannot be determined, the license payments are recognized as revenue over the period of our performance for such undelivered items or services. License fees with ongoing involvement or performance obligations are recorded as deferred revenue, included in Accrued expenses or Other long-term liabilities, when received and generally are recognized ratably over the period of such performance obligation only after both the license period has commenced and we have delivered the technology.

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 six months ended June 30, 2013, we recorded $14.8 million of revenue from the transfer of intellectual property, of which $12.5 million related to the sale of substantially all of our assets in the field of RNA interference to RXi Pharmaceuticals Corporation (“RXi”) during the first quarter of 2013. Refer to Note 5.

Revenue from milestone payments related to arrangements under which we have continuing performance obligations are recognized as Revenue from transfer of intellectual property upon achievement of the milestone only if all of the following conditions are met: the milestone payments are non-refundable; there was substantive uncertainty at the date of entering into the arrangement that the milestone would be achieved; the milestone is commensurate with either the vendor’s performance to achieve the milestone or the enhancement of the value of the delivered item by the vendor; the milestone relates solely to past performance; and the amount of the milestone is reasonable in relation to the effort expended or the risk associated with the achievement of the milestone. If any of these conditions are not met, the milestone payments are not considered to be substantive and are, therefore, deferred and recognized as Revenue from transfer of intellectual property over the term of the arrangement as we complete our performance obligations.

Allowance for doubtful accounts

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.

Equity-based compensation

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 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.

Segment reporting

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 pharmaceuticals 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 and Brazil. The diagnostics segment consists of two operating segments, our (i) pathology operations we acquired through the acquisition of OURLab 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

Variable interest entities. The consolidation of VIEs 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.

Investments

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.

Recent accounting pronouncements

Recent accounting pronouncements. In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, (“ASU 2013-2”). ASU 2013-2 requires the presentation of reclassifications out of accumulated other comprehensive income in either (1)the notes or (2)the face of the financial statements. We adopted ASU 2013-2 for our first quarter ended March 31, 2013. The adoption of ASU 2013-2 did not have a material impact in our condensed consolidated financial statements, but did require certain additional disclosures.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 and six months ended June 30, 2013, are not necessarily indicative of the results of operations and cash flows that may be reported for the remainder of 2013 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, 2012.

Reclassifications. Certain prior year amounts in the condensed consolidated financial statements have been reclassified to conform with the 2013 presentation. Due to the acquisition of OPKO OURLab, LLC (formerly Prost-Data, Inc.), our CLIA-certified laboratory business (“OURLab”) in December 2012, we changed our segment presentation to include diagnostics as a reportable segment. As a result of this change in reportable segments, we restated certain prior year amounts in the condensed consolidated financial statements to conform with the 2013 presentation. These reclassifications had no impact on our results of operations. Refer to Note 12.

Principles of consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of OPKO Health, Inc., 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. Goodwill and other intangible assets acquired in business combinations, licensing and other transactions at June 30, 2013 and December 31, 2012 were $364.9 million and $176.2 million, respectively.

Assets acquired and liabilities assumed in business combinations, licensing and other transactions are recognized at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recognized as goodwill. We determined the fair value of intangible assets, including in-process research and development (“IPR&D”), using the “income method.”

Goodwill is tested at least annually for impairment, or when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable, on an enterprise level by assessing qualitative factors or performing a quantitative analysis in determining whether it is more likely than not that its fair value exceeds the carrying value.

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 June 30, 2013 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.

In evaluating the fair value information, considerable judgment is required to interpret the market data used to develop the estimates. The use of different market assumptions and/or different valuation techniques may have a material effect on the estimated fair value amounts. Accordingly, the estimates of fair value presented herein may not be indicative of the amounts that could be realized in a current market exchange. Refer to Note 8.

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 June 30, 2013 and December 31, 2012, 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 in Fair value changes of 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 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 and six months ended June 30, 2013, revenue from services also includes $0.2 million and $0.4 million, respectively, of revenue related to our consulting agreement with Neovasc, Inc. (“Neovasc”) and to revenue related to molecular diagnostics collaboration agreements. For the three and six months ended June 30, 2012, revenue from services included $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.

Revenue from transfer of intellectual property includes revenue related to the sale, license or transfer of intellectual property such as upfront license payments, license fees and milestone payments received through our license, collaboration and commercialization agreements. We analyze our multiple-element arrangements to determine whether the elements can be separated and accounted for individually as separate units of accounting.

Non-refundable license fees for the out-license of our technology are recognized depending on the provisions of each agreement. We recognize non-refundable upfront license payments as revenue upon receipt if the license has standalone value and the fair value of our undelivered obligations, if any, can be determined. If the license is considered to have standalone value but the fair value of any of the undelivered items cannot be determined, the license payments are recognized as revenue over the period of our performance for such undelivered items or services. License fees with ongoing involvement or performance obligations are recorded as deferred revenue, included in Accrued expenses or Other long-term liabilities, when received and generally are recognized ratably over the period of such performance obligation only after both the license period has commenced and we have delivered the technology.

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 six months ended June 30, 2013, we recorded $14.8 million of revenue from the transfer of intellectual property, of which $12.5 million related to the sale of substantially all of our assets in the field of RNA interference to RXi Pharmaceuticals Corporation (“RXi”) during the first quarter of 2013. Refer to Note 5.

Revenue from milestone payments related to arrangements under which we have continuing performance obligations are recognized as Revenue from transfer of intellectual property upon achievement of the milestone only if all of the following conditions are met: the milestone payments are non-refundable; there was substantive uncertainty at the date of entering into the arrangement that the milestone would be achieved; the milestone is commensurate with either the vendor’s performance to achieve the milestone or the enhancement of the value of the delivered item by the vendor; the milestone relates solely to past performance; and the amount of the milestone is reasonable in relation to the effort expended or the risk associated with the achievement of the milestone. If any of these conditions are not met, the milestone payments are not considered to be substantive and are, therefore, deferred and recognized as Revenue from transfer of intellectual property over the term of the arrangement as we complete our performance obligations.

Total deferred revenue included in Accrued expenses and Other long-term liabilities was $6.0 million and $1.9 million at June 30, 2013 and December 31, 2012, 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 $0.9 million and $0.5 million at June 30, 2013 and December 31, 2012, 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 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 June 30, 2013 and 2012, we recorded $1.8 million and $1.0 million, respectively, of equity-based compensation expense. During the six months ended June 30, 2013 and 2012, we recorded $7.0 million and $2.2 million, respectively, of equity-based compensation expense.

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 pharmaceuticals 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 and Brazil. The diagnostics segment consists of two operating segments, our (i) pathology operations we acquired through the acquisition of OURLab 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 VIEs 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 February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, (“ASU 2013-2”). ASU 2013-2 requires the presentation of reclassifications out of accumulated other comprehensive income in either (1)the notes or (2)the face of the financial statements. We adopted ASU 2013-2 for our first quarter ended March 31, 2013. The adoption of ASU 2013-2 did not have a material impact in our condensed consolidated financial statements, but did require certain additional disclosures. Refer to Note 7.

Business Combinations [Abstract]

ACQUISITIONS, INVESTMENTS, AND LICENSES

ACQUISITIONS, INVESTMENTS, AND LICENSES

PROLOR acquisition

In April 2013, we entered into an Agreement and Plan of Merger (the “PROLOR Merger Agreement”) pursuant to which we will acquire PROLOR Biotech, Inc. (“PROLOR”), a biopharmaceutical company focused on developing and commercializing longer-acting proprietary versions of already approved therapeutic proteins, in an all-stock transaction. Under the terms of the agreement, holders of PROLOR common stock will receive 0.9951 shares of our Common Stock for each share of PROLOR common stock. Based on a price of $7.03 per share of our Common Stock, the transaction is valued at approximately $480 million, or $7.00 per share of PROLOR common stock. The companies expect the transaction to be completed during the second half of 2013. Closing of the transaction is subject to certain conditions including, the approval of PROLOR’s and our stockholders and other customary closing conditions. Dr. Phillip Frost, our Chairman and Chief Executive Officer, is PROLOR’s Chairman of the Board and a greater than 5% stockholder of PROLOR. Dr. Jane H. Hsiao, our Vice Chairman and Chief Technology Officer and Mr. Steven Rubin, our Executive Vice President, Administration, are both directors of PROLOR and less than 5% stockholders of PROLOR. The Board of Directors of each of OPKO and PROLOR (with the directors noted above abstaining) have approved the Merger and the Merger Agreement. In addition, the transaction was also approved by PROLOR’s Strategic Alternatives Committee.

Cytochroma acquisition

In March 2013, we acquired Cytochroma, a corporation located in Markham, Canada, whose lead products, both in Phase 3 development, are Rayaldy^TM, a vitamin D prohormone to treat secondary hyperparathyroidism in patients with stage 3 or 4 chronic kidney disease and vitamin D insufficiency, and Alpharen^TM, a non-absorbed phosphate binder to treat hyperphosphatemia in dialysis patients (the “Cytochroma Acquisition”).

In connection with the Cytochroma 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 Cytochroma Acquisition, or $4.87 per share. The Cytochroma Agreement contains customary representations, warranties, conditions to closing, indemnification rights and obligations of the parties.

In addition, the Cytochroma 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. 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.

The following table summarizes the estimated fair value of the net assets acquired and liabilities assumed in the acquisition of Cytochroma at the date of acquisition, which are subject to change while contingencies that existed on the acquisition date are resolved:

(In thousands)
Current assets (including cash of $378 thousand)	$	1,224
Intangible assets:
In-process research and development	191,530
Patents	210
Total intangible assets	191,740
Goodwill	2,411
Property, plant and equipment	306
Accounts payable and accrued expenses	(1,069		)
Total purchase price	$	194,612

Goodwill is principally related to the acquired workforce. Goodwill is not tax deductible for income tax purposes.

OPKO Brazil asset acquisition

In February 2013, we acquired the assets of OPKO Brazil, a Brazilian pharmaceutical company, pursuant to a purchase agreement entered into on December 26, 2012. Pursuant to the purchase agreement, we paid $0.3 million in cash and delivered 64,684 shares of our Common Stock at closing valued at $0.4 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 $6.73 per share. The number of shares issued was based on the average closing price per share of Common Stock as reported on the NYSE for the 10 trading days immediately preceding the execution of the purchase agreement, or $4.64 per share.

We accounted for this acquisition as an asset acquisition rather than a business combination. As a result we recorded the assets at fair value, with most of the value being allocated to the most significant asset, its pharmaceutical business licenses.

OURLab acquisition

In October 2012, we entered into a definitive merger agreement to acquire OURLab, a Nashville-based CLIA laboratory. In December 2012, we paid $9.4 million in cash and delivered 7,072,748 shares of our Common Stock at closing valued of $32.9 million based on the closing sales price per share of our Common Stock as reported by the NYSE on the actual closing date of the acquisition, or $4.65 per share. The number of shares issued was based on the average closing price per share of our Common Stock as reported on the NYSE for the 15 trading days immediately preceding the execution of the purchase agreement, or $4.33 per share. Pursuant to the merger agreement, 1,732,102 shares of Common Stock issued in the transaction are being held in a separate escrow account to secure the indemnification obligations of OURLab.

Farmadiet acquisition

In August 2012, we entered into a stock purchase agreement pursuant to which we acquired all of the outstanding stock of Farmadiet Group Holding, S.L. (“Farmadiet”), a Spanish company engaged in the development, manufacture, marketing, and sale of pharmaceutical, nutraceutical, and veterinary products in Europe (the “Farmadiet Transaction”).

In connection with the Farmadiet Transaction, we agreed to pay an aggregate purchase price of €13.5 million (approximately $16.0 million), of which (i) 50% ($8.4 million) was paid in cash at closing, and (ii) 50% (the “Deferred Payments”) will be paid, at our option, in cash or shares of our Common Stock as follows: (x) 25% to be paid on the first anniversary of the closing date; and (y) 25% to be paid 18 months after the closing date. On the date of acquisition, we recorded the €6.8 million Deferred Payments at $7.8 million, net of a discount of $0.6 million. The discount will be amortized as interest expense through the respective payment dates. The Deferred Payments are required to be paid in Euro and as such, the final U.S. dollar amount to be paid will be based on the exchange rate at the time the Deferred Payments are made. In the event we elect to pay the Deferred Payments in shares of our Common Stock, the number of shares issuable shall be calculated using the average closing price per share of our Common Stock as reported on the NYSE for the 10 trading days immediately preceding the applicable payment date. On August 2, 2013, we issued 585,703 shares of our Common Stock, in accordance with the first Deferred Payment. The number of shares issued was based on the average closing price per share of our Common Stock as reported on the NYSE for the 10 trading days up to and including August 1, 2013, or $7.61 per share. We have the right to hold back up to €2.8 million (approximately $3.6 million as of June 30, 2013) from the Deferred Payment to satisfy indemnity claims.

In connection with the Farmadiet Transaction, we also entered into two ancillary transactions (the “Ancillary Transactions”). In exchange for a 40% interest held by one of the sellers in one of Farmadiet’s subsidiaries, we agreed to issue up to an aggregate of 250,000 shares of our Common Stock, of which (a) 125,000 shares were issued on the closing date, and (b) 125,000 will be issued upon achieving certain milestones. In addition, we acquired an interest held by an affiliate of Farmadiet in a product in development in exchange for which we agreed to pay up to an aggregate of €1.0 million ($1.3 million) payable at our option in cash or shares of our Common Stock, of which (a) 25% ($0.3 million) was paid at closing through delivery of 70,421 shares of our Common Stock, and 75% ($1.0 million) will be paid in cash or shares of our Common Stock upon achieving certain milestones. As a result, we recorded $1.2 million as contingent consideration for the future consideration. We evaluate the contingent consideration on an ongoing basis and the changes in fair value are recognized in earnings until the milestones are achieved. Refer to Note 8. The final U.S. dollar amount to be paid will be based on the exchange rate at the time the milestones are achieved. The number of shares of our Common Stock issued is determined based on the average closing sales price for our Common Stock on the NYSE for the 10 trading days preceding the required payment date.

ALS acquisition

In April 2012, we completed the acquisition of ALS Distribuidora Limitada (“ALS”), a privately-held Chilean pharmaceutical company, pursuant to a stock purchase agreement entered into in January 2012. In connection with the transaction, we agreed to pay up to a total of $4.0 million in cash to the sellers. Pursuant to the purchase agreement, we paid (i) $2.4 million in cash at the closing, less certain liabilities, and (ii) $0.8 million in cash at the closing into a separate escrow account to satisfy possible indemnity claims. During the six months ended June 30, 2013, we paid the remaining $0.8 million that we had agreed to pay upon the legal registration in the name of ALS of certain trademarks and product registrations previously held by the former owner of ALS, Arama Laboratorios y Compañía Limitada.

Neovasc

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 three months ended June 30, 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.

2013 licensing agreements

An element of our growth strategy is to leverage our proprietary technology through a combination of internal development, acquisition, and external partnerships to maximize the commercial opportunities for our portfolio of proprietary pharmaceutical and diagnostic products.

Pharmsynthez transactions

On April 18, 2013, we entered into a series of concurrent transactions with OAO Pharmsynthez (“Pharmsynthez”), a Russian pharmaceutical company traded on the Moscow Stock Exchange. The transactions consisted of:

•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 shares of its common shares to us or to pay us Russian Rubles (“RUR”) 265.0 million ($8.1 million) on or before December 31, 2013 (the "Pharmsynthez Note Receivable").

• We have 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 shares of Pharmsynthez common shares (the “Purchase Option”). 

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

We recorded the initial shares received in Pharmsynthez as an equity method investment.  We recorded the Pharmsynthez Note Receivable, and the Purchase Option, as financial instruments and elected the fair value option for subsequent measurement. Changes in the fair value of the receivable from Pharmsynthez for its common stock or RUR, with the embedded derivative, and the Purchase Option are recorded in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2013

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.  

RXi transactions

In March 2013, we completed the sale to 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”). In accounting for the sale of the RNAi Assets, we determined that we did not have any continuing involvement in the development of the RNAi Assets or any other future performance obligations and, as a result, during the six months ended June 30, 2013, we recognized the APA Shares as $12.5 million of revenue from transfer of intellectual property in our Condensed Consolidated Statement of Operations.

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.

Investments in variable interest entities

We have determined that we hold variable interests in Fabrus, Inc. (“Fabrus”), Biozone Pharmaceutical, Inc. (“BZNE”) and SciVac Ltd ("SciVac"), previously known as SciGen (I.L.) Ltd. We made this determination as a result of our assessment that they do not have sufficient resources to carry out their principal activities without additional financial support.

In order to determine the primary beneficiary of BZNE, we evaluated our investment and our related parties’ investments, as well as our investment combined with the related party group’s investments to identify if we had the power to direct the activities that most significantly impact the economic performance of BZNE. We determined that power to direct the activities that most significantly impact BZNE’s economic performance is conveyed through the board of directors of BZNE and no entity is able to appoint the BZNE governing body that oversees its executive management team. Based on the capital structure, governing documents and overall business operations of BZNE, we determined that, while a VIE, no single entity has the power to direct the activities that most significantly impact BZNE’s economic performance. However, we determined that we and our related parties can significantly influence the success of BZNE through our voting power. As such, we account for investment in BZNE under the equity method.

In order to determine the primary beneficiary of Fabrus, we evaluated our investment and our related parties’ investment, as well as our investment combined with the related party group’s investment to identify if we had the power to direct the activities that most significantly impact the economic performance of Fabrus. We determined that power to direct the activities that most significantly impact Fabrus’s economic performance is conveyed through the board of directors of Fabrus as no entity is able to appoint the Fabrus governing body that oversees its executive management team. Based on the capital structure, governing documents and overall business operations of Fabrus, we determined that, while a VIE, no single entity has the power to direct the activities that most significantly impact Fabrus’s economic performance. We did determine, however, that our related parties can significantly influence the success of Fabrus through our board representation and voting power. Accordingly, as we and our related parties have the ability to exercise significant influence over Fabrus’ operations, we account for our investment in Fabrus under the equity method.

Consolidated variable interest entities

In June 2012, we entered into a share and debt purchase agreement whereby in exchange for $0.7 million we acquired shares representing a 45% stock ownership in SciVac from FDS Pharma LLP (“FDS”). SciVac is a privately-held Israeli company that produces a third-generation hepatitis B-vaccine. In November 2012, March 2013 and May 2013, we loaned to SciVac a combined $1.2 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 SciVac and record 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 June 30, 2013 and December 31, 2012. These assets are owned by, and these liabilities are obligations of, SciVac, not us.

Loss Per Share

6 Months Ended

Jun. 30, 2013

Earnings Per Share [Abstract]

LOSS PER SHARE

LOSS PER SHARE

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 by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of common stock options and common stock warrants is determined by applying the “treasury stock” method. Potentially dilutive shares issuable pursuant to the Notes (defined in Note 6) were not included in the computation of net loss per share for the three and six months ended June 30, 2013, because their inclusion would be anti-dilutive.

Also, a total of 29,701,838 and 27,416,029 potential shares of Common Stock have been excluded from the calculation of net loss per share for the three months ended June 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive. A total of 29,910,492 and 27,243,783 potential shares of Common Stock have been excluded from the calculation of net loss per share for the six months ended June 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive.

During the three months ended June 30, 2013, 216,053 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised and issued.

During the six months ended June 30, 2013, 1,727,746 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 1,612,232 shares of Common Stock. Of the 1,727,746 Common Stock options and Common Stock warrants exercised, 115,514 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the warrant agreements.

RELATED PARTY TRANSACTIONS

In January 2013, we entered into the Notes, with the Purchasers for the sale of $175.0 million aggregate principal amount of Notes in a private placement in reliance on exemptions from registration under the Securities Act. The Purchasers of the 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 Notes were issued on January 30, 2013.

In December 2012, we entered into a five-year lease agreement with AVI Properties, LLC (“AVI”), an entity affiliated with Dr. Jonathan Oppenheimer, OURLab’s Chief Executive Officer. The lease is for approximately 44,000 square feet of laboratory and office space in Nashville, Tennessee, where OURLab is based. The lease provides for payments of approximately $18 thousand per month in the first year, increasing annually if the consumer price index exceeds 5%, plus applicable sales tax. In addition to the rent, we pay a portion of operating expenses, property taxes and parking.

During the six months ended June 30, 2013, our FineTech subsidiary recorded revenue of $0.1 million for the sale of APIs to Teva Pharmaceutical Industries, Limited ("Teva"). Dr. Frost serves as the Chairman of the Board of Directors of Teva.

In February 2012, we entered into a cooperative research funding and option agreement with The Scripps Research Institute (“TSRI”) to support research for the development of novel oligomeric compounds relating to our molecular diagnostics technology (the “Research Agreement”). Pursuant to the Research Agreement, we agreed to provide funding of approximately $0.9 million annually over a five year period. In conjunction with entering into the Research Agreement, we also entered into a license agreement with TSRI for technology relating to libraries of peptide tertiary amides. In addition, we entered into a second license with TSRI for technology relating to highly selective inhibitors of c-Jun-N-Terminal Kinases that may be useful for the treatment of various diseases, including Parkinson’s disease. We also entered into a research funding and option agreement to provide funding of approximately $0.2 million annually over three years to support further development of the technology. Dr. Frost served as a Trustee for TSRI until November 2012 and Dr. Richard Lerner, a member of our Board of Directors, served as its President until December 2011.

In February 2012, we made a $1.0 million investment in ChromaDex. Other investors participating in the private financing included the Gamma Trust, Hsu Gamma, and Dr. Lerner. Following our investment, we own 1.5% of ChromaDex, the Gamma Trust owns approximately 16% of ChromaDex; Hsu Gamma owns approximately 1%; and certain of our directors own less than 1% of ChromaDex.

In February 2012, we purchased from BZNE $1.7 million of 10% secured convertible promissory notes (the “BZNE Notes”), convertible into BZNE common stock at a price equal to $0.20 per common share, which BZNE Notes are due and payable on February 24, 2014 and ten year warrants to purchase 8.5 million shares of BZNE common stock at an exercise price of $0.40 per share.

Mr. Roberto Prego Novo is the Chairman of BZNE and presently serves as a consultant to us. Dr. Frost and Mr. Prego Novo previously invested in BZNE in February and March, 2011. On May 16, 2011, BZNE acquired the assets and assumed the liabilities of Aero Pharmaceuticals, Inc. (“Aero”) in exchange for which BZNE issued an aggregate of 8,331,396 shares of its restricted common stock to Aero. On September 21, 2011, BZNE issued an additional 13,914 shares to Aero due to the late filing of a registration statement. Prior to the transaction, Dr. Frost, through the Gamma Trust, beneficially owned approximately 46% of Aero’s issued and outstanding capital stock; Mr. Prego Novo owned approximately 23% of Aero’s issued and outstanding capital stock through Olyrca Trust; and Dr. Hsiao beneficially owned approximately 12% of Aero’s issued and outstanding stock. Each of Drs. Frost and Hsiao and Mr. Prego Novo beneficially owned approximately 9.2%, 1.7%, and 8.2% of BZNE, respectively, following the purchase of Aero by BZNE. Mr. Rubin beneficially owns less than 1% of BZNE as a result of his prior ownership of Aero shares. In April 2012 and June 2012, Dr. Frost, through the Gamma Trust, also made loans to BZNE in the principal amounts of $0.3 million and $0.1 million, respectively, which were initially secured by a first priority lien on a particular BZNE receivable. The notes to Gamma Trust were subsequently amended and Gamma Trust no longer holds a security interest in the BZNE receivables.

In August 2011, we made an investment in Neovasc. Dr. Frost and other members of our management are shareholders of Neovasc. Prior to the investment, Dr. Frost beneficially owned approximately 36% of Neovasc, Dr. Hsiao owned approximately 6%, and Mr. Rubin owned less than 1%. Dr. Hsiao and Mr. Rubin also serve on the board of directors of Neovasc.

In November 2010, we made an investment in Fabrus. In exchange for the investment, we acquired approximately 13% of Fabrus on a fully diluted basis. Our investment was part of a $2.1 million financing for Fabrus. Other investors participating in the financing include the Gamma Trust and Hsu Gamma. In connection with the financing, Drs. Frost and Hsiao joined the Fabrus Board of Managers. Dr. Lerner owns approximately 5% of Fabrus. Mr. Vaughn Smider, Founder and CEO of Fabrus, is an Assistant Professor at TSRI. Dr. Frost served as a Trustee for TSRI until November 2012, and Dr. Lerner served as President of TSRI until December 2011.

In June 2010, we entered into a cooperative research and development agreement with Academia Sinica, Taipei, Taiwan (“Academia Sinica”), for pre-clinical work for a compound against various forms of cancer. Dr. Alice Yu, a member of our Board of Directors, is a Distinguished Research Fellow and Associate Director at the Genomics Research Center, Academia Sinica (“Genomics Research Center”). In connection with the Academia Sinica Agreement, we are required to pay Academia Sinica approximately $0.2 million over the term of the agreement.

Effective in September 2009, we entered into an agreement pursuant to which we invested $2.5 million in Cocrystal in exchange for 1,701,723 shares of Cocrystal’s Convertible Series A Preferred Stock. A group of investors, led by the Frost Group LLC, which is a trust controlled by Dr. Frost, Dr. Hsaio and Mr. Rubin, (the “Cocrystal Investors”), previously invested $5.0 million in Cocrystal, and agreed to invest an additional $5.0 million payable in two equal installments in September 2009 and March 2010. As a result of an amendment to the Cocrystal Investors’ agreements dated June 9, 2009, we, rather than the Cocrystal Investors, made the first installment investment ($2.5 million) on September 21, 2009.

In June 2009, we entered into a stock purchase agreement with Sorrento, pursuant to which we invested $2.3 million in Sorrento Therapeutics, Inc. ("Sorrento"). In exchange for the investment, we acquired approximately one-third of the outstanding common shares of Sorrento and received a fully-paid, exclusive license to the Sorrento antibody library for the discovery and development of therapeutic antibodies in the field of ophthalmology. On September 21, 2009, Sorrento entered into a merger transaction with Quikbyte Software, Inc. (“Quikbyte”). Prior to the merger transaction, certain investors, including Dr. Frost and other members of our management group, made an investment in Quikbyte. Dr. Lerner serves as a consultant and scientific advisory board member to Sorrento and owns less than one percent of its shares.

In November 2007, we entered into an office lease with Frost Real Estate Holdings, LLC (“Frost Holdings”), an entity affiliated with Dr. Frost. The lease is for approximately 8,300 square feet of space in an office building in Miami, Florida, where our principal executive offices are located. The lease provides for payments of approximately $18 thousand per month in the first year increasing annually to $24 thousand per month in the fifth year, plus applicable sales tax. The rent is inclusive of operating expenses, property taxes and parking. The rent for the first year was reduced to reflect a $30 thousand credit for the costs of tenant improvements. In August 2012, we entered into a six-month extension on the same terms as the 2007 expiring lease and in February 2013, we agreed to extend the lease on a month-to-month basis for up to an additional six months.

We reimburse Dr. Frost for Company-related use by Dr. Frost and our other executives of an airplane owned by a company that is beneficially owned by Dr. Frost. We reimburse Dr. Frost in an amount equal to the cost of a first class airline ticket between the travel cities for each executive, including Dr. Frost, traveling on the airplane for Company-related business. We do not reimburse Dr. Frost for personal use of the airplane by Dr. Frost or any other executive; nor do we pay for any other fixed or variable operating costs of the airplane. For the three and six months ended June 30, 2013, we reimbursed Dr. Frost approximately $5 thousand and $18 thousand, respectively, for Company-related travel by Dr. Frost and other OPKO executives. For the three and six months ended June 30, 2012, we reimbursed Dr. Frost approximately $65 thousand and $129 thousand, respectively, for Company-related travel by Dr. Frost and other OPKO executives.

Debt Disclosure [Abstract]

DEBT

DEBT

In January 2013, we entered into note purchase agreements (the “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 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 Notes were issued on January 30, 2013. The 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 Notes will mature on February 1, 2033, unless earlier repurchased, redeemed or converted. Upon a fundamental change as defined in the instruments governing the Notes, subject to certain exceptions, the holders may require us to repurchase all or any portion of their Notes for cash at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus any accrued and unpaid interest to but not including the fundamental change repurchase date.

The Notes will be convertible at any time on or after November 1, 2032, through the second scheduled trading day immediately preceding the maturity date, at the option of the holders. Additionally, holders may convert their Notes prior to the close of business on the scheduled trading day immediately preceding November 1, 2032, under the following circumstances: (1) conversion based upon satisfaction of the trading price condition relating to the Notes; (2) conversion based on the Common Stock price; (3) conversion based upon the occurrence of specified corporate events; or (4) if we call the Notes for redemption. The Notes will be convertible into cash, shares of our Common Stock, or a combination of cash and shares of Common Stock, at our election unless we have made an irrevocable election of net share settlement. The initial conversion rate for the Notes will be 141.4827 shares of Common Stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $7.07 per share of Common Stock), and will be subject to adjustment upon the occurrence of certain events. In addition, we will, in certain circumstances, increase the conversion rate for holders who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture) and holders who convert upon the occurrence of certain specific events prior to February 1, 2017 (other than in connection with a make-whole fundamental change).

We may not redeem the Notes prior to February 1, 2017. On or after February 1, 2017 and before February 1, 2019, we may redeem for cash any or all of the Notes but only if the last reported sale price of our Common Stock exceeds 130% of the applicable conversion price for at least 20 trading days during the 30 consecutive trading day period ending on the trading day immediately prior to the date on which we deliver the redemption notice. The redemption price will equal 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest to but not including the redemption date. On or after February 1, 2019, we may redeem for cash any or all of the Notes at a redemption price of 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest up to but not including the redemption date.

The terms of the Notes, include, among others: (i) rights to convert into shares of our Common Stock, including upon a fundamental change; and (ii) a coupon make-whole payment in the event of a conversion by the holders of the Notes on or after February 1, 2017 but prior to February 1, 2019. We have determined that these specific terms are considered to be embedded derivatives. As a result, embedded derivatives are required to be separated from the host contract, the Notes, and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; and (b) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. We have concluded that the embedded derivatives within the Notes meet these criteria and, as such, must be valued separate and apart from the Notes and recorded at fair value each reporting period.

For purposes of accounting and financial reporting, we combine these embedded derivatives and value them together as one unit of accounting. At each reporting period, we record these embedded derivatives at fair value which is included as a component of the Notes on our Condensed Consolidated Balance Sheets.

We have used a binomial lattice model in order to estimate the fair value of the embedded derivative in the Notes. A binomial lattice model generates two probable outcomes — one up and another down —arising at each point in time, starting from the date of valuation until the maturity date. A lattice was initially used to determine if the Notes would be converted, called or held at each decision point. Within the lattice model, the following assumptions are made: (i) the Notes will be converted early if the conversion value is greater than the holding value; or (ii) the Notes will be called if the holding value is greater than both (a) the redemption price (as defined in the Indenture) and (b) the conversion value plus the coupon make-whole payment at the time. If the Notes are called, then the holder will maximize their value by finding the optimal decision between (1) redeeming at the redemption price and (2) converting the Notes.

Using this lattice, we valued the embedded derivatives using the “with-and-without method,” where the value of the Notes including the embedded derivatives is defined as the “with,” and the value of the Notes excluding the embedded derivatives is defined as the “without.” This method estimates the value of the embedded derivatives by looking at the difference in the values between the Notes with the embedded derivatives and the value of the Notes without the embedded derivatives.

The lattice model requires the following inputs: (i) price of our Common Stock; (ii) Conversion Rate (as defined in the Indenture); (iii) Conversion Price (as defined in the Indenture); (iv) maturity date; (v) risk-free interest rate; (vi) estimated stock volatility; and (vii) estimated credit spread for the Company.

The following table sets forth the inputs to the lattice model used to value the embedded derivative:

	June 30, 2013			Issuance Date
Stock price	$	7.10		$	6.20
Conversion Rate	141.4827			141.4827
Conversion Price	$	7.07		$	7.07
Maturity date	February 1, 2033			February 1, 2033
Risk-free interest rate	1.57		%	1.12		%
Estimated stock volatility	35		%	40		%
Estimated credit spread	983 basis points			944 basis points

The following table sets forth the fair value of the Notes with and without the embedded derivatives, and the fair value of the embedded derivatives as of the issuance date and June 30, 2013:

(In thousands)	June 30, 2013		Issuance Date
Fair value of Notes:
With the embedded derivatives	$	189,481	$	175,000
Without the embedded derivatives	$	115,402	$	115,796
Estimated fair value of the embedded derivatives	$	74,079	$	59,204

Changes in certain inputs into the lattice model can have a significant impact on changes in the estimated fair value of the embedded derivatives. For example, a decrease in our estimated credit spread results in an increase in the estimated value of the embedded derivatives. Conversely, a decrease in the price of our Common Stock results in a decrease in the estimated fair value of the embedded derivatives. From the date the Notes were issued through June 30, 2013, we observed an increase in the market price of our Common Stock which resulted in a $14.9 million increase in the estimated fair value of our embedded derivatives recorded in Fair value changes of derivative instruments, net in our Condensed Consolidated Statements of Operations.

The principal amounts, unamortized discount and net carrying amounts of the Notes as of June 30, 2013 were as follows:

(In thousands)	Principal Balance		Unamortized Discount		Net Carrying Amount
Notes	$	175,000	$	60,555	$	114,445

We have entered into line of credit agreements with fifteen financial institutions in Chile and Spain. These lines of credit are used primarily as a source of working capital for inventory purchases.

The following table summarizes the amount outstanding under the lines of credit:

At June 30, 2013 and December 31, 2012, the weighted average interest rate on our lines of credit was approximately 6.4% and 6.5%, respectively.

At June 30, 2013 and December 31, 2012, we had mortgage notes and other debt payables related to Farmadiet as follows:

COMMITMENTS AND CONTINGENCIES

In connection with our acquisitions of CURNA, OPKO Diagnostics, FineTech, Farmadiet, and Cytochroma, we agreed to pay future consideration to the sellers upon the achievement of certain events. As a result, as of June 30, 2013 , we recorded $68.9 million as contingent consideration, with $5.3 million recorded within Accrued expenses and $63.6 million recorded within Other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets. Refer to Note 4.

On April 29, 2013, we were named in a putative class action filed in the Eighth Judicial District Court in and for Clark County, Nevada against PROLOR Biotech, Inc. (“PROLOR”), the members of the PROLOR Board of Directors, individually (including Drs. Frost and Hsiao and Steven Rubin), and the Company. From May 1, 2013 through May 6, 2013, we were named in an additional five putative class actions suits filed in the Eighth Judicial District Court in and for Clark County, Nevada against the same defendants. On July 17, 2013, these suits were consolidated, for all purposes, into an amended class action complaint as part of the In re PROLOR Biotech, Inc. Shareholders' Litigation (Case No. A-13-680860-B). The lawsuit is brought by purported holders of PROLOR's common stock, both individually and on behalf of a putative class of PROLOR's stockholders, asserting claims that (i) PROLOR's directors breached their fiduciary duties in connection with the proposed merger by, among other things, purportedly failing to maximize stockholder value, (ii) PROLOR and its Board of Directors failed to disclose material information concerning the proposed merger, and (iii) the Company aided and abetted PROLOR's directors' alleged breach of their fiduciary duties. The lawsuit seeks various damages, an award of all costs, and reasonable attorneys' fees, as well as certain equitable relief, including enjoining consummation of the merger and, alternatively, rescinding the merger in the event it is consummated. The Company denies the allegations and intends to vigorously defend the actions. It is too early to assess the probability of a favorable or unfavorable outcome or the loss or range of loss, if any.

In November 2012, Adrian Goldstein, M.D., a former employee of OURLab, filed a complaint for declaratory judgment and alleged breach of contract against OURLab in the Chancery Court for Davidson County, Tennessee. Dr. Goldstein asserts in his complaint that OURLab breached his employment agreement and owes him additional compensation and further compensation for the value of OURLab under a “compensation for sale” provision set forth in his employment agreement. Dr. Goldstein seeks recovery of compensatory damages not to exceed $20 million, plus his attorney’s fees and litigation expenses. OURLab believes this action is without merit and is vigorously defending against plaintiff’s claims. It is too early to assess the probability of a favorable or unfavorable outcome or the loss or range of loss, if any.

In October 2012, we received a letter from counsel to Optos, Inc., making certain indemnity claims against us in connection with the sale of our ophthalmic instrumentation business. It is too early to assess the likelihood of litigation in this matter or the probability of a favorable or unfavorable outcome. However, we do not currently believe this matter will have a material impact on our results of operations or financial condition.

In July 2012, OURLab received a letter from AdvanceMed Corporation (“AdvanceMed”) regarding a post-payment review conducted by AdvanceMed (the “Post-Payment Review Letter”). The Post-Payment Review Letter originated with a post payment review audit by AdvanceMed of 183 claims submitted by OURLab to the Medicare program. OURLab believes that its billing practices were appropriate and it is following the appeal process set forth by Medicare. OURLab received a partially favorable determination, which reduced the amount of the alleged overpayment, and it continues to appeal the remaining alleged overpayments. No assurances can be given about the outcome of the appeal.

We are a party to other litigation in the ordinary course of business. We do not believe that any such litigation will have a material adverse effect on our business, financial condition, or results of operations.

We expect to incur substantial losses as we continue the development of our product candidates, continue our other research and development activities, and establish a sales and marketing infrastructure in anticipation of the commercialization of our diagnostic and pharmaceutical product candidates. We currently have limited commercialization capabilities, and it is possible that we may never successfully commercialize any of our diagnostic and pharmaceutical product candidates. We do not currently generate revenue from any of our diagnostic and pharmaceutical product candidates. Our research and development activities are budgeted to expand over a period of time and will require further resources if we are to be successful. As a result, we believe that our operating losses are likely to be substantial over the next several years. We may need to obtain additional funds to further develop our research and development programs, and there can be no assurance that additional capital will be available to us on acceptable terms, or at all.
