Jeff Park, Interim CEO, commented “Diplomat reached a new high mark this quarter in which the incredible team we’ve built executed on our plan and achieved record revenues.  Our first quarter demonstrated strong performance in both our Specialty segment and our PBM segment — relaunched last week under its new brand, CastiaRx.  Our PBM integration has progressed rapidly, and as our innovation, growth and profitability initiatives continue to gain momentum, we believe we can drive substantial market share gains over time and generate long term value for all our stakeholders.”

First Quarter Financial Summary:

Revenue for the first quarter of 2018 was $1,342 million, compared to $1,079 million in the first quarter of 2017, an increase of $263 million or 24%.  Revenue was comprised of $1,153 million and $191 million from our Specialty segment and our newly formed Pharmacy Benefit Management (“PBM”) segment, respectively.  There was a $2.0 million inter-company elimination of revenue, and associated cost of sales, between the segments.  The increase in our Specialty segment revenue was primarily driven by $31 million of revenue from our other acquisitions as well as manufacturer price increases, access to dispense drugs that were new in the past year and increased volume through payor relationships.  These increases were partially offset by a decrease in hepatitis C business versus the prior year period and drug mix.

Gross profit in the first quarter of 2018 was $110.6 million and generated an 8.2% gross margin, compared to $85.0 million gross profit and 7.9% gross margin in the first quarter of 2017.  Gross profit was comprised of $93.0 million and $17.6 million from our Specialty segment and PBM segment, respectively.  The gross margin increase in the quarter was primarily due to the impact of our PBM acquisitions, which includes all contracts reflected on a net revenue basis with associated product and service cost of goods, as well as the impact of the acquired entities in our Specialty segment, and manufacturer price increases in the first quarter of 2018 versus the prior year period.

Selling, general, and administrative expenses (“SG&A”) for the first quarter of 2018 were $101.9 million, an increase of $25.4 million, compared to $76.5 million in the first quarter of 2017.  This increase is primarily driven by $11.5 million related to employee cost, including employee cost for our acquired entities and stock option compensation.  Also contributing to the SG&A expense increase was a $7.5 million increase in amortization expense from definite-lived intangible assets, including the capitalized software for internal use, associated with our acquired entities and a one-time $2.1 million severance and merger and acquisition expense associated with our acquired entities.  We also experienced increases in other SG&A; including, freight, building and equipment, travel, insurance, and other miscellaneous expenses.

Net (loss) income attributable to Diplomat for the first quarter of 2018 was $(0.5) million compared to $4.4 million in the first quarter of 2017.  This decrease was primarily driven by an $8.4 million increase in interest expense due to a significant increase in outstanding debt to fund our PBM acquisitions, partially offset by an income tax benefit of $0.9 million in the first quarter of 2018 versus income tax expense of $2.3 million in the prior year period.  The income tax benefit during the first quarter of 2018 was inclusive of a $0.3 million excess tax benefit related to share-based awards.  Adjusted EBITDA for the first quarter of 2018 was $39.6 million compared to $26.8 million in the first quarter of 2017, an increase of $12.8 million.

Earnings per share for the first quarter of 2018 was $(0.01), compared to $0.07 for the first quarter of 2017.  On a diluted basis, earnings per share was $(0.01) in the first quarter of 2018, compared to $0.06 in the prior year period.  Diluted non-GAAP adjusted earnings per share (“Adjusted EPS”) was $0.20 in the first quarter of this year compared to $0.19 in the first quarter of 2017.

2018 Financial Outlook

For the full-year 2018, we are increasing our revenue guidance to account for the earlier than anticipated transition to account for revenue in our PBM segment on a gross basis.  We are maintaining our previous financial guidance on all other financial measures:

·                  Revenue between $5.5 and $5.9 billion, versus the previous range of $5.3 and $5.6 billion

·                  Net income attributable to Diplomat between $4.5 and $13.0 million

·                  Adjusted EBITDA between $164 and $170 million

·                  Diluted EPS between $0.06 and $0.17

·                  Adjusted EPS between $0.87 and $0.97

Our EPS and Adjusted EPS expectations assume approximately 74,900,000 weighted average common shares outstanding on a diluted basis and a tax rate of 24% and 27%, for the low- and high-end of the range, respectively, for the full year 2018, which could differ materially.

Non-GAAP Information

Adjusted EPS adds back, net of income taxes, the impact of all merger and acquisition related expenses, including amortization of intangible assets, the change in fair value of contingent consideration, as well as transaction-related costs.  We exclude merger and acquisition-related expenses from Adjusted EPS because we believe the amount of such expenses in any specific period may not directly correlate to the underlying performance of our business operations and such expenses can vary significantly between periods as a result of new acquisitions, full amortization of previously acquired intangible assets, or ultimate realization of contingent consideration.  Investors should note that acquisitions, once consummated, contribute to revenue in the periods presented as well as future periods and should also note that amortization and contingent consideration expenses may recur in future periods.  A reconciliation of Adjusted EPS, a non-GAAP measure, to EPS as prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) can be found below.

We define Adjusted EBITDA as net income (loss) attributable to Diplomat before interest expense, income taxes, depreciation and amortization, share-based compensation, change in fair value of contingent consideration and other merger and acquisition-related expenses, restructuring and impairment charges, and certain other items that we do not consider indicative of our ongoing operating performance (which are itemized below in the reconciliation to net (loss) income attributable to Diplomat).  Adjusted EBITDA is not in accordance with, or an alternative to, GAAP.  In addition, this non-GAAP measure is not based on any comprehensive set of accounting rules or principles.  You should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in the presentation, and we do not infer that our future results will be unaffected by unusual or non-recurring items.

We consider Adjusted EBITDA and Adjusted EPS to be supplemental measures of our operating performance.  We present Adjusted EBITDA and Adjusted EPS because they are used by our Board of Directors and management to evaluate our operating performance.  Adjusted EBITDA is also used as a factor in determining incentive compensation, for budgetary planning and forecasting overall financial and operational expectations, for identifying underlying trends, and for evaluating the effectiveness of our business strategies.  Further, we believe they assist us, as well as investors, in comparing performance from period-to-period on a consistent basis.  Other companies in our industry may calculate Adjusted EBITDA and Adjusted EPS differently than we do and these calculations may not be comparable to our Adjusted EBITDA and Adjusted EPS metrics.  A reconciliation of Adjusted EBITDA, a non-GAAP measure, to net (loss) income attributable to Diplomat can be found below.
