Raising Full Year 2015 Guidance

FLINT, Mich., May 11, 2015 /PRNewswire/ — Diplomat Pharmacy, Inc. (NYSE: DPLO), the nation’s largest independent specialty pharmacy, announced financial results for the quarter ended March 31, 2015. All comparisons, unless otherwise noted, are to the quarter ended March 31, 2014.

First Quarter 2015 Highlights include:

·                  Revenue of $625 million, an increase of 34%

·                  Total prescriptions dispensed of 194,000, an increase of 6%

·                  Gross margin of 6.6% versus 6.3%

·                  Adjusted EBITDA of $11.2 million, an increase of 36%

·                  Adjusted EPS of $0.09, versus $0.05

Phil Hagerman, Chairman and CEO of Diplomat, commented, “We’re pleased with the first quarter results, as Diplomat continued to benefit from strong specialty pharmacy industry trends and further gained market share. Our role as the largest independent specialty pharmacy in the nation, combined with our dedication to our high touch patient model allowed us to win access to several limited distribution drug panels in the quarter. As we’ve previously stated, we remain focused on growing our high margin businesses and saw success in this area during the quarter. With the successful completion of the BioRx acquisition on April 1, 2015, we have established a platform on which we will drive our specialty infusion business. 2015 is off to a great start and I’m enthusiastic about our outlook for the remainder of the year.”

First Quarter Financial Summary:

Revenue for the first quarter of 2015 was $624.9 million, compared to $465.7 million in the first quarter of 2014, an increase of $159.2 million or 34%. The increase was the result of approximately $58 million of revenue from drugs that were new to the market or newly dispensed by Diplomat and approximately $24 million from our acquisitions. The remaining increase is primarily attributable to a richer mix of high-priced drugs, the impact of manufacturer price increases and payor mix changes.

Gross profit in the first quarter of 2015 was $41.1 million, compared to $29.5 million in the first quarter of 2014 and generated gross margin of 6.6% compared to 6.3%. The gross margin improvement in the quarter was driven by drug mix changes, including the impact of the acquisitions, and continued favorable pricing trends.

Selling, general, and administrative expenses (“SG&A”) for the first quarter of 2015 was $36.3 million compared to $23.5 million in the first quarter of 2014. As a percentage of revenue, SG&A accounted for 5.8% of total revenues compared to 5.1% in the year ago period. Of this increase, $5.5 million relates to our acquisitions; including expense for their pharmacies and support staff during the first quarter, an increase in the fair value of contingent consideration, and amortization expense from definite-lived intangible assets.  Absent the impact of the acquisitions, SG&A as a percentage of revenue was essentially flat year over year.  The remaining increase in SG&A is attributable to all other operating expenses, including but not limited to an increased mix of more labor-intensive

drugs, expenses associated with our continued information technology investments and new costs associated with being a public company.

Net income allocable to common shareholders for the first quarter of 2015 was $2.9 million, or $0.06 per common share, compared to $1.6 million, or $0.05 per common share for the first quarter of 2014.  On a diluted basis, we had net income per common share of $0.05 in the first quarter of this year, compared to $0.05 per common share in the year ago quarter.  Diluted non-GAAP Adjusted EPS (“Adjusted EPS”) was $0.09 in the first quarter of this year compared to $0.05 in the first quarter of 2014. Our weighted average common shares outstanding in the first quarter of 2015 were significantly impacted by our IPO on October 9, 2014, as all pre-IPO common and preferred shares converted to a single class of common stock upon the IPO, and we also issued 11.0 million new shares of common stock in the IPO.

Adjusted EBITDA for the first quarter of 2015 was $11.2 million versus $8.2 million in the first quarter of 2014, an increase of 36%.

2015 Financial Outlook

For the full-year 2015, we are increasing our financial guidance.  We now expect:

·                  Revenue between $2.9 and $3.1 billion, up from our previous range of $2.8 to $3.1 billion

·                  Net income between $14 and $16 million, up from our previous range of $12 to $14 million

·                  Adjusted EBITDA between $64 and $68 million, up from our previous range of $63 to $67 million

·                  Adjusted EPS between $0.48 and $0.51, up from our previous range of $0.47 to $0.50; this does account for the additional common shares issued in our March 2015 follow-on equity offering and the recent BioRx transaction.

Our Adjusted EPS expectations now assume approximately 62,400,000 weighted average common shares outstanding for the full 2015 year, which could differ materially. All of these metrics include contribution from our April 1, 2015 acquisition of BioRx, interest expense associated with our new credit facility, and the impact of our recent common stock offering.

Non-GAAP Information

Adjusted EPS adds back, net of taxes, the impact of all merger and acquisition related expenses, including amortization of intangible assets, the change in contingent consideration related to our recent acquisitions, as well as deal-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 will 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 in the appendix.

We define Adjusted EBITDA as net income (loss) before interest expense, income taxes, depreciation and amortization, share-based compensation, restructuring and impairment charges, equity loss and impairment of non-consolidated entities, and certain other items that we do not consider indicative of our ongoing operating performance (which items are itemized below in the reconciliation to net income). 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. They are 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. 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.  Further, 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 income can be found in the appendix.
