Key First Quarter 2015 Accomplishments and Recent Developments

● Revenue of approximately $1.6 million during the first quarter of 2015, compared to $2,000 during the first quarter of 2014;

● Adjusted EBITDA of approximately $(2.3) million during the first quarter of 2015, compared to $(1.6) million during the first quarter of 2014;

● Commenced construction efforts of an 8,600 square foot leased facility in Roxbury, New Jersey. Once completed, this facility is expected to serve as a new location for the company’s New Jersey-based pharmacy and include a separate outsourcing facility intended to comply with cGMP manufacturing standards and Section 503B of the U.S. Food, Drug, and Cosmetic Act;

● Launched the company’s combination drop therapy topical eye drop formulations and corresponding LessDrops™ education campaign at the American Society of Cataract and Refractive Surgery annual meeting in San Diego, California in April 2015;

● Over 300 physicians have started prescribing the company’s Dropless Therapy™ injectables;

● Launched the company’s urology business and began dispensing prescriptions for its Hep-Lido-A (HLA) compounded formulation for interstitial cystitis (IC), the cornerstone of its urology business. Also introduced the company’s new Tri-Mix lyophilized compounded formulations for the treatment of erectile dysfunction (ED). The company is exhibiting its proprietary compounded formulations and introducing both the Defeat IC™ and ED Free™ educational campaigns at the upcoming American Urological Association Annual Meeting, the largest meeting of urologists in the world, May 16-18, 2015, in New Orleans;

● Entered into term loan agreement with an affiliate of Life Sciences Alternative Funding LLC (LSAF) for up to a $15 million in proceeds. LSAF has provided the company with $10 million to date and may provide up to an additional $5 million on or before May 11, 2016, at the company’s option and subject to the company’s satisfaction of certain revenue milestones prior to May 11, 2016.

Mark L. Baum, Chief Executive Officer of Imprimis, stated, “This quarter was a record quarter for the company as we continued to grow our commercialization efforts and invest in the growth of our key programs. Compared to the prior year, we saw top-line expansion and we expect this positive trend to continue as we execute our compounded pharmaceutical development and commercialization business model. Our Dropless Therapy™ formulation sales increased, during first quarter 2015 and we dispensed approximately 14,800 units. We expect sales to continue to increase moving forward as our customer base grows. We look forward to leveraging the proceeds of our recent loan agreement to further our commercialization and distribution efforts as we move into the latter part of this year and into 2016. With our ophthalmology and urology commercial platforms now in place, once we complete our production infrastructure we believe we will be well-positioned for sustained growth and future profitability.”

Financial Summary

Selected highlights regarding operating results for the first quarter ended March 31, 2015 and the same period in 2014 are as follows (in thousands, expect per share data):

	For the three months ended March 31, 2015			For the three months ended March 31, 2014
Total Revenues	$	1,563		$	2
Cost of Sales		1,007			-
Selling & Marketing Expenses		1,012			382
General & Administrative Expenses		2,480			1,895
Research & Development Expenses		181			60
Other Income, net		24			10
Net Loss	$	(3,093	)	$	(2,325	)

Adjusted EBITDA

In addition to the company’s results of operations determined in accordance with U.S. generally accepted accounting principles (GAAP), which are presented and discussed above, management also utilizes adjusted EBITDA, an unaudited financial measure that is not calculated in accordance with GAAP, to evaluate the company’s financial results and performance and to plan and forecast future periods. Adjusted EBITDA is considered a “non-GAAP” financial measure within the meaning of Regulation G promulgated by the SEC. Management believes that this non-GAAP financial measure reflects an additional way of viewing aspects of the company’s operations that, when viewed with GAAP results, provides a more complete understanding of the company’s results of operations and the factors and trends affecting its business. Management believes adjusted EBITDA provides meaningful supplemental information regarding the company’s performance because (i) it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making; (ii) it excludes the impact of non-cash or, when specified, non-recurring items that are not directly attributable to the company’s core operating performance and that may obscure trends in the company’s core operating performance; and (iii) it is used by institutional investors and the analyst community to help analyze the company’s results. However, adjusted EBITDA and any other non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. Further, non-GAAP financial measures used by the company and the manner in which they are calculated may differ from the non-GAAP financial measures or the calculations of the same non-GAAP financial measures used by other companies, including the company’s competitors.

The company defines adjusted EBITDA as net income (loss) excluding the effects of interest, taxes, depreciation, amortization, stock-based compensation, other income (expense) and, if any and when specified, other non-recurring income or expense items. The company believes that the most directly comparable GAAP financial measure to adjusted EBITDA is net loss. Adjusted EBITDA has limitations and should not be considered as an alternative to gross profit or net loss as a measure of operating performance or to net cash provided by (used in) operating, investing or financing activities as a measure of ability to meet cash needs.

The following is a reconciliation of adjusted EBITDA to the most comparable GAAP measure, net loss, for the three months ended March 31, 2015 and 2014 (in thousands):

	For the three months ended March 31, 2015			For the three months ended March 31, 2014
Net Loss	$	(3,093	)	$	(2,325	)
Stock-based compensation		658			688
Depreciation		44			3
Amortization		82			-
Interest (income) expense, net		7			(10	)
Other income		(31	)		-
Adjusted EBITDA	$	(2,333	)	$	(1,644	)
