United Therapeutics Corporation (Nasdaq: UTHR) today announced its financial results for the fourth quarter and year ended December 31, 2018.

"2018 was a truly transformative year for United Therapeutics. We signed four major agreements to acquire new product candidates, including an in-licensing agreement for ralinepag, representing our largest deal to date," said Martine Rothblatt, Ph.D., Chairman and Chief Executive Officer of United Therapeutics. "At the same time, we continued to execute against our existing commercial and clinical goals, including the successful readout of our FREEDOM-EV clinical trial, significant progress toward near-term phase III readouts for our BEAT and DISTINCT studies, and an increase to a record number of patients being treated with our treprostinil therapies."

Revenues for the quarter and year ended December 31, 2018 decreased by $83.3 million and $97.5 million, respectively, as compared to the same periods in 2017.

Remodulin net product sales for the quarter and year ended December 31, 2018 decreased by $21.0 million and $71.9 million, respectively, as compared to the same periods in 2017. For the quarter and year ended December 31, 2018, international Remodulin net sales decreased by $30.7 million and $90.0 million, respectively, compared to the same periods in 2017, primarily due to the transfer of additional regulatory and commercial responsibilities to an international distributor in the third quarter of 2017. As a result of this transfer, we recognized $23.7 million and $47.4 million of net product sales in the quarter and year ended December 31, 2017, respectively, related to the one-time purchase of Remodulin inventory by that distributor and we reduced the price at which we sell Remodulin to that distributor. The remaining decrease was primarily due to a reduction in quantities shipped to that distributor. For the quarter and year ended December 31, 2018, U.S. Remodulin net sales increased by $9.7 million and $18.1 million, respectively, compared to the same periods in 2017, primarily due to a price increase that was implemented in April 2018, which was the first price increase for Remodulin since 2010, and an increase in the number of patients being treated with Remodulin. For the year ended December 31, 2018, these increases were partially offset by the one-time $4.5 million impact of a change in contractual minimum inventory levels with a U.S. distributor, as discussed below.

Tyvaso net product sales for the quarter and year ended December 31, 2018 increased by $14.5 million and $42.3 million, respectively, as compared to the same periods in 2017. These increases were primarily due to price increases that were implemented in April 2017 and January 2018 and the reversal in the fourth quarter of 2018 of an estimated $15.4 millionliability for Medicaid rebates, of which $13.6 million was initially recorded in 2017. In addition, Tyvaso net product sales increased due to an increase in the number of patients being treated with Tyvaso. These increases were offset by (1) the impact of replacing $6.2 million of commercial Tyvaso product that our specialty pharmaceutical distributor previously used in connection with a clinical trial; and (2) the one-time $3.5 million impact of a change in contractual minimum inventory levels with a U.S. distributor, as discussed below.

Adcirca net product sales for the quarter and year ended December 31, 2018 decreased by $77.6 million and $96.0 million, respectively, as compared to the same periods in 2017. These decreases were primarily due to the launch of a generic version of Adcirca in August 2018, partially offset by price increases that were implemented by Eli Lilly and Company in May 2017 and January 2018. In addition, we increased our allowance for product returns for Adcirca by $16.4 million in the third quarter of 2018 based on our estimates of inventory held by distributors and other downstream customers that would expire unsold as a result of the increased use of a generic version of Adcirca.

Orenitram net product sales for the quarter and year ended December 31, 2018 increased by $1.6 million and $19.3 million, respectively, as compared to the same periods in 2017. These increases were primarily due to an increase in the number of patients being treated with Orenitram, a price increase that was implemented in January 2018 and, for the year ended December 31, 2018, the one-time $3.7 million impact of a change in contractual minimum inventory levels with a U.S. distributor, as discussed below.

Unituxin net product sales decreased by $0.8 million for the quarter ended December 31, 2018 and increased by $8.8 million for the year ended December 31, 2018, as compared to the same periods in 2017. For the year ended December 31, 2018, Unituxin net product sales increased due to an increase in the number of vials sold and price increases that were implemented in April and December 2017.

During the fourth quarter of 2017, we amended our agreements with one of our U.S. specialty pharmacy distributors, in part to make the monthly minimum inventory requirement consistent across Remodulin, Tyvaso and Orenitram. This change resulted in a one-time decrease in total net product sales of $4.3 million as the distributor adjusted to the new contractual inventory requirement levels in the first quarter of 2018. On an individual product basis, net product sales of Remodulin decreased by $4.5 million, net product sales of Tyvaso decreased by $3.5 million, and net product sales of Orenitram increased by $3.7 million.

Cost of product sales, excluding share-based compensation. The decrease in cost of product sales of $14.5 million for the quarter ended December 31, 2018, as compared to the same period in 2017, was primarily attributable to a decrease in Adcirca sales.

The increase in cost of product sales of $98.8 million for the year ended December 31, 2018, as compared to the same period in 2017, was primarily attributable to a $96.9 million increase in royalty expense for Adcirca. As a result of an amendment to our license agreement with Lilly, effective December 1, 2017, our royalty rate on net product sales of Adcirca increased from five percent to an effective rate of approximately 42.5 percent.

Research and development expense, excluding share-based compensation. We continued to invest in our product pipeline during 2018, which includes products in multiple phase III clinical trials in cardiopulmonary diseases and oncology as well as programs in regenerative medicine and organ manufacturing. The increase in research and development expense of $48.4 million for the quarter ended December 31, 2018, as compared to the same period in 2017, was primarily due to an up-front payment of $45.0 million under our license agreement with MannKind.

The increase in research and development expense of $113.6 million for the year ended December 31, 2018, as compared to the same period in 2017, was driven by an increase of $95.9 million in research and development expense for the treatment of cardiopulmonary diseases, primarily due to up-front payments of $55.0 million under our license and research agreements with MannKind and $10.0 million under our license agreement with Samumed, increased spending of $22.9 million on the development of drug delivery devices, including the Implantable System for Remodulin and RemUnity, and increased spending on several clinical and non-clinical studies. Research and development expense for cancer-related projects increased by $13.9 million due to an increase in spending on the DISTINCT study. Research and development expense for organ manufacturing projects increased by $3.9 million due to increased preclinical work on technologies designed to increase the supply and distribution of transplantable organs and tissues.

General and administrative, excluding share-based compensation. The increase in general and administrative expenses of $6.7 million for the quarter ended December 31, 2018, as compared to the same period in 2017, primarily resulted from a $5.0 million increase in consulting fees.

The increase in general and administrative expenses of $14.7 million for the year ended December 31, 2018, as compared to the same period in 2017, primarily resulted from: (1) a $10.3 million increase in consulting expenses; (2) a $4.7 millionincrease in compensation due to an increase in staffing; and (3) a $4.4 million increase in acquisition and integration costs related to the SteadyMed acquisition. The increase was partially offset by a $7.1 million decrease in legal fees incurred in connection with intellectual property litigation and a Department of Justice (DOJ) investigation.

Sales and marketing, excluding share-based compensation. Sales and marketing expenses for the quarter ended December 31, 2018, remained relatively consistent as compared to the same period in 2017.

The decrease in sales and marketing expenses of $5.2 million for the year ended December 31, 2018, as compared to the same period in 2017, primarily resulted from a decrease in marketing consulting fees.

Share-based compensation. The decreases in share-based compensation of $115.7 million and $99.9 million, respectively, for the quarter and year ended December 31, 2018, were primarily due to decreases in STAP expense of $117.9 million and $120.5 million, respectively, primarily driven by a decrease in our stock price for the quarter and year ended December 31, 2018, as compared to the same periods in 2017. The decrease in STAP expense for the year-ended December 31, 2018 was partially offset by an increase of $15.5 million in stock option expense due to additional awards granted and outstanding in 2018 and a $5.1 million increase in restricted stock unit expense due to additional awards granted and outstanding in 2018.

Settlement of Loss Contingency

In December 2017, we entered into a civil Settlement Agreement with the U.S. Government to resolve a DOJ investigation. During the second quarter of 2017, we recorded a $210.0 million accrual relating to this matter, and ultimately paid this amount, plus interest, to the U.S. Government upon settlement.

Impairments of Investments in Privately-Held Companies

During the years ended December 31, 2018 and 2017, we recorded impairment charges of $53.5 million and $49.6 million, respectively, related to our investments in privately-held companies.

Income Taxes

The provision for income taxes was $169.7 million for the year ended December 31, 2018, compared to $351.6 million for the same period in 2017. The change in the provision for income taxes was primarily due to the impacts of The Tax Cuts and Jobs Act (Tax Reform) and the nondeductible portion of an accrual in 2017 in connection with a civil settlement with the DOJ. For the years ended December 31, 2018 and 2017, the effective tax rates were approximately 22 percent and 46 percent, respectively.

Non-GAAP Earnings

Non-GAAP earnings is defined as net income, adjusted for: (1) share-based compensation expense (including expenses relating to stock options, restricted stock units, share tracking awards, and our employee stock purchase plan); (2) loss contingency; (3) impairments of investments in privately-held companies; (4) license fees; (5) impact of Tax Reform; and (6) tax impact on non-GAAP earnings adjustments.
