“We expect multiple catalysts to drive growth and build long-term value at Eagle. This includes expanding our existing bendamustine and RYANODEX portfolios by taking advantage of product and label expansion opportunities, as well as protecting the franchises with our robust patent estate and exclusivity. We believe that advancing several of our late-stage opportunities targeting attractive new markets will open additional paths for growth and profitability for years to come,” stated Scott Tarriff, Chief Executive Officer of Eagle Pharmaceuticals.

“We have decided to launch our tentatively approved bendamustine hydrochloride 500ml solution, subject to receipt of final approval from the FDA, which we have recently requested.  We believe that we are uniquely positioned to fill a need with the segment of the population that requires an alternative to TREANDA®, but at a lower price point to BENDEKA.  Over time, this would provide us with more control over our revenue growth and allow us to better manage our business. We continue to believe BENDEKA is a tremendous product with many patient and caregiver benefits.  Teva is doing a very good job for us and we are pleased with their accomplishments.  We view the launch of a “big bag” formulation as complementary, enabling us to provide additional value to a cost-conscious segment of the market, while at the same time allowing Eagle to increase profitability,” added Tarriff.

“We also look forward to advancing RYANODEX for EHS with another clinical study at the Hajj in August of this year, adding to the positive data we have already collected. Our fulvestrant study is now fully underway with results anticipated later this year. In addition, with what we believe is a first-to-file ANDA submission for vasopressin accepted for filing, as well as our progress on a second ANDA product, we are excited about these added opportunities to create value for patients and shareholders,” concluded Tarriff.

First Quarter 2018 Financial Results

Total revenue for the three months ended March 31, 2018 was $46.6 million, as compared to $76.8 million for the three months ended March 31, 2017 (which included a $25 million milestone payment from Teva).  A summary of total revenue is outlined below:

Gross margin was 75% in the first quarter of 2018, as compared to 77% in the first quarter of 2017.

Research and development expenses increased to $17.3 million for the first quarter of 2018, compared to $7.5 million in the first quarter of 2017, largely due to external clinical costs associated with the fulvestrant clinical study, which completed randomization of 600 subjects during the first quarter of 2018. Excluding stock-based compensation and other non-cash and non-recurring items, R&D expense during the first quarter of 2018 was $15.0 million.

SG&A expenses decreased to $15.2 million in the first quarter of 2018 compared to $18.6 million in the first quarter of 2017. The decrease was due to the expiration of the Spectrum co-promotion agreement at the end of June 2017, as well as a reduction in marketing expenses.  These reductions were partially offset by the increase in personnel-related expenses associated with the expansion of our sales force during the second quarter of 2017. Excluding stock-based compensation and other non-cash and non-recurring items, first quarter 2018 SG&A expense was $10.5 million.

Net income for the first quarter of 2018 was $2.6 million, or $0.18 per basic and $0.17 per diluted share, compared to net income of $22.9 million, or $1.50 per basic and $1.42 per diluted share in the three months ended March 31, 2017, due to the factors discussed above.

Adjusted Non-GAAP net income for the first quarter of 2018 was $8.2 million, or $0.55 per basic and $0.53 per diluted share, compared to Adjusted Non-GAAP net income of $26.5 million or $1.74 per basic and $1.64 per diluted share in the first quarter of 2017. For a full reconciliation of Adjusted Non-GAAP net income to the most comparable GAAP financial measures, please see the tables at the end of this press release.

Liquidity

As of March 31, 2018, the Company had $95.7 million in cash and cash equivalents and $53.4 million in net accounts receivable, $42 million of which was due from Teva.  The Company had $48.8 million in outstanding debt.

We purchased $7 million of Eagle common stock as part of our expanded $100 million share buyback program. Since August 2016, we have repurchased $88 million of our common stock. During the first quarter of 2018, we paid $15 million in cash to settle the Arsia milestones.

2018 Expense Guidance

2018 R&D expense is expected to be in the range of $46 - $50 million.  This reflects ongoing expenses for (i) the enrollment of fulvestrant and RYANODEX for EHS clinical trials; (ii) API outlays for the fulvestrant and vasopressin programs; and (iii) additional preclinical assays for the RYANODEX nerve agent program. Excluding stock-based compensation and other non-cash and non-recurring items, R&D expense is expected to be in the range of $40 - $44 million.

2018 SG&A expense is expected to be in the range of $61 - $64 million. Excluding stock-based compensation and other non-cash and non-recurring items, SG&A expense is expected to be in the range of $44 - $47 million.

Non-GAAP Financial Performance Measures

In addition to financial information prepared in accordance with U.S. GAAP, this press release also contains adjusted net income and adjusted earnings per share from continuing operations attributable to Eagle Pharmaceuticals. The Company believes these measures provide investors and management with supplemental information relating to operating performance and trends that facilitate comparisons between periods and with respect to projected information.

Adjusted net income from continuing operations excludes share-based compensation expense, depreciation, amortization of acquired intangible assets, changes in contingent purchase price, non-cash interest expense and tax adjustments. The Company believes these non-GAAP financial measures help indicate underlying trends in the Company’s business and are important in comparing current results with prior period results and understanding projected operating performance. Non-GAAP financial measures provide the Company and its investors with an indication of the Company’s baseline performance before items that are considered by the Company not to be reflective of the Company’s ongoing results. See the attached Reconciliation of GAAP to Adjusted Non-GAAP Net Income and Adjusted Non-GAAP Earnings per Share and Reconciliation of GAAP to Adjusted Non-GAAP EBITDA for explanations of the amounts excluded and included to arrive at adjusted net income and adjusted earnings per share amounts, and adjusted non-GAAP EBITDA amounts, respectively, for the three-month periods ended March 31, 2018 and 2017.

These adjusted measures are non-GAAP and should be considered in addition to, but not as a substitute for, the information prepared in accordance with U.S. GAAP. The Company strongly encourages investors to review its consolidated financial statements and publicly-filed reports in their entirety and cautions investors that the non-GAAP measures used by the Company may differ from similar measures used by other companies, even when similar terms are used to identify such measures.
