DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION ​ Description of Business ​ Diplomat Pharmacy, Inc. and its consolidated subsidiaries (the “Company”) is the largest independent provider of specialty pharmacy and infusion services in the United States of America (“U.S.”). The Company is focused on improving the lives of patients with complex chronic diseases while also delivering unique solutions for manufacturers, hospitals, payors and providers. The Company’s patient-centric approach positions it at the center of the healthcare continuum for the treatment of complex chronic disease states, including oncology, specialty infusion therapies, immunology, hepatitis, multiple sclerosis and many other serious or long-term conditions. The Company operates in two reportable segments - Specialty and Pharmacy Benefit Management (“PBM”). The Specialty segment offers a broad range of innovative solutions to address the dispensing, delivery, dosing and reimbursement of clinically intensive, high-cost specialty drugs and a wide range of applications. The PBM segment provides services designed to help customers reduce the cost and manage the complexity of their prescription drug programs. The Company dispenses to patients in all U.S. states and territories through its advanced distribution centers and manages centralized clinical call centers to deliver localized services on a national scale. ​ Basis of Presentation ​ Unaudited Condensed Consolidated Financial Statements ​ These unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements include all adjustments of a normal recurring nature necessary for a fair presentation of the financial position, results of operations, cash flows and changes in shareholders’ equity for the periods presented. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or for any future annual or interim period. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Annual Report”). ​

NEW ACCOUNTING STANDARDS

NEW ACCOUNTING STANDARDS
NEW ACCOUNTING STANDARDS	2. NEW ACCOUNTING STANDARDS ​ Adoption of New Accounting Standard ​ Leases ​ The Company adopted Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842) ​ The Company adopted Topic 842 as of January 1, 2019 using the optional transition method, which allowed entities to apply the new guidance at the adoption date and record a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, and not to restate the comparative periods presented. Therefore, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. The adoption of the standard resulted in the recognition of net operating lease right-of-use assets of approximately $28,400 and operating lease liabilities of approximately $29,300 on the Condensed Consolidated Balance Sheet as of January 1, 2019 primarily related to its real estate operating leases. The operating lease right-of-use assets includes the impact of deferred rent. The Company does not have any finance leases. ​ Also, upon adoption, the Company recorded a cumulative-effect adjustment, after tax, of $5,652 (a valuation allowance was established against the full amount of the net deferred taxes of $1,387) to increase retained earnings for the amount of a previously deferred gain on a sale-leaseback transaction that closed in 2018. Such gain recorded on the sale-leaseback transaction would have been fully recognized under Topic 842. ​ The Company elected to apply the package of practical expedients upon transition, which includes no reassessment of whether existing contracts are or contain leases and allowed for the lease classification for existing leases to be retained. The Company did not elect the practical expedient to use hindsight, and accordingly the initial lease term did not differ under the new standard versus prior accounting practice. After transition, in certain instances, the cost of renewal options will be recognized earlier in the term of the lease than under the previous lease accounting rules. The operating lease agreements include lease and non-lease components for which the Company elected the practical expedient to not separate non-lease components from the lease components but instead to combine them and account for them as a single lease component and will continue to do so for its real estate operating leases. The Company has selected as its accounting policy to keep leases with a term of twelve months or less off the balance sheet and recognize these lease payments on a straight-line basis over the lease term. ​ The Company has recorded operating lease right-of-use assets and operating lease liabilities in its Condensed Consolidated Balance Sheets at June 30, 2019. The lessors’ rate implicit in the operating leases was not available to the Company and was not determinable from the terms of the lease. Therefore, the Company used its incremental borrowing rate to determine the present value of the future lease payments. The incremental borrowing rates were not observable and therefore, the rates were estimated primarily using a methodology dependent on the Company’s financial condition, creditworthiness, and availability of certain observable data. In particular, the Company considered its actual cost of borrowing for collateralized loans and its credit rating, along with the corporate bond yield curve in estimating its incremental borrowing rates. These estimated incremental borrowing rates were applied to future lease payments to determine the present value of the operating lease liability for each lease. ​ The new standard did not have a significant impact on the timing or measurement of lease expense in the Condensed Consolidated Statements of Comprehensive Loss and had no impact on the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019. As noted above, the comparative prior period information for the six months ended June 30, 2018 has not been adjusted and continues to be reported under the Company’s historical lease recognition policies under ASC Topic 840, Leases. ​ The disclosure requirements of Topic 842 are included within Note 13, Leases. ​ Accounting Standards Issued But Not Yet Adopted ​ Credit Losses ​ In June 2016, the Financial Accounting Standards Board issued ASU No. 2016-13, Financial Instruments— Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, ​

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	​ 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Principles of Consolidation ​ The Condensed Consolidated Financial Statements include the accounts of Diplomat Pharmacy, Inc., and its wholly owned subsidiaries. ​ All intercompany transactions and balances have been eliminated in consolidation. ​ Use of Estimates ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from these estimates. ​ Receivables, net ​ Receivables, net consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2019 2018 ​ Trade receivables, net of allowances of $(29,166) and $(25,342), respectively ​ $ 314,864 ​ $ 299,407 ​ Rebate receivables ​ 9,964 ​ 22,375 ​ Other receivables ​ 4,767 ​ 4,820 ​ ​ ​ $ 329,595 ​ $ 326,602 ​ ​ Trade receivables are stated at the invoiced amount. Trade receivables primarily include amounts due from clients, third-party pharmacy benefit managers and insurance providers and are based on contracted prices. Trade receivables are unsecured and require no collateral. Trade receivable terms vary by payor, but generally are due within 30 days after the sale of the product or performance of the service. ​ Rebate receivables are amounts due from pharmaceutical manufacturers related to drug purchases by participants of the various pharmacy benefit plans that the Company manages, a portion of which, depending on contract terms, are paid back to the Company’s customers. The Company estimates these rebates at period-end based on its contractual arrangements with its manufacturers and such rebates are recorded as a reduction of cost of sales. ​ Inventories ​ Inventories consist of prescription and over-the-counter medications and are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Prescription medications are returnable to the Company’s vendors and fully refundable before six months of expiration, and any remaining expired medication is relieved from inventory on a quarterly basis.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	4. FAIR VALUE MEASUREMENTS ​ The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy was established, which prioritizes the inputs used in measuring fair value as follows: ​ Level 1: ​ Level 2: ​ Level 3: ​ An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should maximize the use of observable inputs and minimize the use of unobservable inputs. ​ Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques: ​ A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. ​ B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost). ​ C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models). ​ The following table presents the placement in the fair value hierarchy of liabilities that are measured and disclosed at fair value on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Asset / ​ ​ Valuation ​ ​ Valuation ​ ​ ​ (Liability) Level 2 Level 3 Technique June 30, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration $ (6,838) $ — ​ $ (6,838) C Interest rate swaps (Note 7) ​ ​ (9,777) ​ ​ (9,777) ​ ​ — A ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2018: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration $ (6,895) $ — ​ $ (6,895) C Interest rate swaps (Note 7) ​ ​ (4,292) ​ ​ (4,292) ​ ​ — A ​ The following table sets forth the change in contingent consideration (Level 3 measurements) for the six months ended June 30, 2019: ​ ​ ​ ​ ​ ​ ​ Contingent ​ Consideration Balance at January 1, 2019 ​ $ (6,895) Change in fair value ​ ​ 57 Payments ​ — Balance at June 30, 2019 ​ $ (6,838) ​ The carrying amount of the Company’s debt approximates fair value due to variable interest rates at customary terms and rates the Company could obtain in current financing.

GOODWILL AND DEFINITE-LIVED INTANGIBLE ASSETS
GOODWILL AND DEFINITE-LIVED INTANGIBLE ASSETS	5. GOODWILL AND DEFINITE-LIVED INTANGIBLE ASSETS ​ Goodwill ​ Goodwill is not subject to amortization and is reviewed at least annually in the fourth quarter of each year using data as of December 31 of that year, or earlier if an event occurs or circumstances change and there is an indication of impairment. The Company determined, due to lower than expected second quarter results and the resulting impact on future forecasts, that there was an indication of impairment for both the Specialty and PBM segments and, as a result, tested goodwill in the interim period at June 30, 2019 at the reporting unit level. The impairment test consists of comparing a reporting unit’s fair value to its carrying value. Based on the interim impairment test as of June 30, 2019, the Company determined that the fair value of the Diplomat Specialty Pharmacy (“DSP”) and PBM reporting units were less than their respective carrying value. As a result, the Company recorded total non-cash impairment charges of $122,891 to goodwill and $17,979 to definite-lived intangible assets. ​ The estimated fair value for each of the reporting units was determined using the income approach. With the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. We use our internal forecasts to estimate future cash flows and include an estimate of long-term growth rates based on our most recent views of the long-term outlook for each reporting unit. Such projections contain management’s best estimates of growth rates in revenue and costs and future expected changes in operating margins and cash expenditures, which are based on factors including our best estimates of economic and market conditions over the projected period. Our projection of estimated operating results and cash flows are discounted using a weighted average cost of capital that reflects current market conditions appropriate to each reporting unit. The discount rate is sensitive to changes in interest rates and other market rates in place at the time the assessment is performed. The discount rates used in the reporting unit valuations as of June 30, 2019 were 10.5% for the DSP reporting unit and 11.75% for the PBM reporting unit. ​ For the DSP reporting unit, as of and for the second quarter of 2019, the Company experienced lower than expected results, which have impacted the outlook for the remainder of 2019 and into 2020. The lowered outlook for the DSP reporting unit includes slower than anticipated brand to generic conversions and delays in the release of generic versions of certain drugs which tend to provide higher margin contribution. Additionally, anticipated cost savings are running behind forecast primarily due to delays in the implementation of ScriptMed, our new specialty operating platform and while the previous outlook assumed additional investment in the Company’s payor sales team would have resulted in new business opportunities that would offset anticipated negative impacts to volume, the Company has seen limited impacts from this investment on 2019 results through June 30, 2019. Lastly, while it was believed the business environment would stabilize, the Company continues to see volumes in our DSP reporting unit business being negatively impacted by member channel management and increased competition from larger, vertically-integrated peers and a reimbursement environment in specialty pharmacy that is driving continued downward pressure on margins. As such, these conditions resulted in downward revisions of the forecasts on current and future projected earnings and cash flows from the DSP reporting unit. ​ During the second quarter of 2019, the Company recorded a non-cash goodwill impairment of $68,218 for the Specialty segment, all of which was allocated solely to the DSP reporting unit. The non-cash impairment charge is not deductible for income tax purposes. The impairment loss is recorded in the caption “Goodwill impairments” in the Condensed Consolidated Statements of Comprehensive Loss. After the impairment charge, the adjusted carrying value of the Specialty segment goodwill was $272,442 at June 30, 2019, of which zero was allocated to the DSP reporting unit. ​ The goodwill in the PBM segment was recorded as a result of two separately acquired entities (i) Pharmaceutical Technologies, Inc. d/b/a National Pharmaceutical Services, acquired in November 27, 2017, and (ii) LDI Holding Company, LLC, acquired December 20, 2017. ​ For the PBM reporting unit, in the second quarter of 2019, the Company experienced lower than expected results driven by continued business losses and lower earned rebates due to drug mix and slightly lower rebate retention. These lower than expected results resulted in downward revisions of the forecasts on current and future projected earnings and cash flows of the PBM reporting unit and a more conservative outlook in 2020 and beyond. ​ During the second quarter of 2019, the Company recorded a non-cash goodwill impairment of $54,673 for the PBM segment, which is not deductible for income tax purposes. The impairment loss is recorded in the caption “Goodwill impairment” in the Condensed Consolidated Statements of Comprehensive Loss. After the impairment charge, the adjusted carrying value of the PBM segment goodwill was $214,121 at June 30, 2019. ​ Also, the Company in connection with the goodwill impairment analysis assessed whether the carrying amounts of the reporting units long-lived assets may not be recoverable and therefore may be impaired. To assess the recoverability at the DSP reporting unit and PBM segment asset group level, the undiscounted cash flows of the DSP and PBM businesses were analyzed over a range of potential remaining useful lives. As a result, the Company determined that certain trade names and trademarks, certain customer and physician relationships in the DSP and PBM reporting units and certain non-compete employment agreements in its DSP reporting unit were not recoverable and were impaired. The Company recorded an impairment loss of $16,772 to therefore fully impair the remaining intangible assets at the DSP reporting unit, which is part of the Specialty segment, and an impairment loss of $1,207 to further impair those intangible assets at the PBM reporting unit, which is the only reporting unit in the PBM segment.

At June 30, 2019, the total compensation cost related to nonvested options not yet recognized was $10,704 which will be recognized over a weighted average period of 2.1 years, assuming all employees complete their respective service periods for vesting of the options. ​ The Company granted annual awards of 366,330 options under its 2014 Omnibus Incentive Plan (the “2014 Plan”) and an inducement award of 87,478 options to purchase common stock to key employees during the six months ended June 30, 2019, which options become exercisable in installments of 33.3 percent, per year, beginning on the first anniversay of the grant date. These options have a maximum term of ten years. ​ The 453,808 options to purchase common stock that were granted during the six months ended June 30, 2019 have a weighted average grant date fair value of $2.53 per option. The grant date fair values of these stock option awards were estimated using the Black Scholes-Merton option pricing model using the assumptions set forth in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exercise price ​ $ 4.81 ​ ​ $ 5.94 ​ Expected volatility ​ 49.12 % ​ ​ 49.47 % Expected dividend yield ​ 0 % ​ ​ 0 % Risk-free rate for expected term ​ ​ 1.95 % ​ ​ 2.38 % Expected life (in years) ​ ​ 6.00 ​ ​ ​ 6.00 ​ ​ Estimating grant date fair values for employee stock options requires management to make assumptions regarding expected volatility of the value of those underlying shares, the risk-free rate over the expected life of the stock options and the date on which share-based payments will be settled. Expected volatility is based on a weighted average of the Company’s historic volatility and an implied volatility for a group of industry-relevant healthcare companies as of the measurement date. Risk-free rate is determined based upon U.S. Treasury rates over the estimated expected option lives. Expected dividend yield is zero as the Company does not anticipate that any dividends will be declared during the expected term of the options. The expected term of options granted is calculated using the simplified method (the midpoint between the end of the vesting period and the end of the maximum term). Forfeitures are accounted for when they occur. ​ Restricted Stock Units (“RSU” or “RSUs”) ​ A summary of the Company’s RSU activity as of and for the six months ended June 30, 2019 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ Number ​ Grant Date ​ of RSUs Fair Value Nonvested at January 1,2019 1,869,029 ​ $ 21.67 Granted 5,864,924 ​ 7.55 Vested and issued ​ (310,936) ​ ​ 20.29 Cancelled /expired (877,119) ​ 22.46 Nonvested at June 30, 2019 6,545,898 ​ $ 8.94 ​ Performance Based RSUs ​ The Company granted an award of 1,498,500 performance-based RSUs as a sign-on inducement award to an executive during the second quarter of 2018. The award will be earned or forfeited based upon the Company’s performance relative to specified cumulative Adjusted EBITDA and revenue goals for the years ending December 31, 2018 and 2019 and the executive’s completion of the service condition. In January 2019, the performance goals were measurable and determinable, therefore, a grant date for accounting purposes was established. During the second quarter of 2019, these performance-based RSUs were modified by (1) adjusting the performance goals so that earning or forfeiture will be based upon the Company’s actual 2018 performance and projected 2019 performance, and (2) including a new performance goal that provides for full vesting at the maximum amount in the event the Company’s stock price increases by a specified percentage over a specified period of time during the 2019 fiscal year as a result of corporate actions taken during the 2019 performance year. The Company accounted for this modification pursuant to ASC Topic 718, “Compensation – Stock Compensation”, as a Type III (Improbable to Probable) modification and changed its estimate of the number of shares that will be earned from 0 percent to 30 percent. ​ During the second quarter of 2019, the Company granted annual awards of 1,835,000 performance-based RSUs under the 2014 Plan and 172,838 performance-based RSUs as an inducement award to key employees. These awards will be earned or forfeited based upon the Company’s performance relative to specified cumulative Adjusted EBITDA and revenue goals, as applicable, for the years ending December 31, 2019 and/or 2020, as applicable and the completion of the service condition. The Company is currently accounting for these performance-based RSUs under the current estimate that 28.6 percent of the award shares will be earned. The Company recorded share-based compensation expense associated with performance-based RSUs of $1,015 and $845 for the three months ended June 30, 2019 and 2018, respectively, and $1,074 and $852 for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019, the total compensation expense related to nonvested performance-based RSUs not yet recognized, assuming 28.6 percent of the shares will be earned, was $3,891, which will be recognized over a weighted average remaining term of 1.28 years, assuming all employees also complete their respective service periods for vesting of the RSUs. ​ Service Based RSUs ​ The Company granted 2,115,377 service-based RSUs under its 2014 Plan and 243,209 service-based RSUs as inducement awards to key employees during the six months ended June 30, 2019. The value of an RSU is determined by the market value of the Company’s common stock at the date of grant. This value is recorded as compensation expense on a straight-line basis over the vesting period, which ranges from one year to three years from grant date. ​ The Company recorded share-based compensation expense associated with service-based RSUs of $2,205 and $3,974 for the three months ended June 30, 2019 and 2018, respectively, and $3,798 and $4,841 for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019, the total compensation cost related to nonvested RSUs not yet recognized was $24,807, which will be recognized over a weighted average remaining term of 2.37 years, assuming all employees complete their respective service periods for vesting of the service-based RSUs. ​ Restricted Stock Awards (“RSA” or RSAs”) ​ A summary of the Company’s RSA activity as of and for the six months ended June 30, 2019 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ Number ​ Weighted ​ ​ of Shares ​ Average ​ ​ Subject to ​ Grant Date ​ Restriction Fair Value Nonvested at January 1, 2019 43,355 ​ $ 20.91 Granted ​ 186,969 ​ ​ 4.51 Vested (20,829) ​ 22.20 Forfeited (5,929) ​ 21.63 Nonvested at June 30, 2019 ​ 203,566 ​ ​ 5.69 ​ Under the 2014 Plan, the Company issued 186,969 RSAs to non-employee directors. The value of a RSA is determined by the market value of the Company’s common stock at the date of grant. The value of a RSA is recorded as share-based compensation expense on a straight-line basis over the vesting period, which is typically one year. ​ The Company recorded share-based compensation expense associated with RSAs of $215 and $139 for the three months ended June 30, 2019 and 2018, respectively, and $341 and $277 for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019, the total compensation cost related to nonvested RSAs not yet recognized was $859 which will be recognized over a weighted average remaining term of 0.87 years, assuming the non-employee directors complete their service period for vesting of the RSAs.

LOSS PER COMMON SHARE
LOSS PER COMMON SHARE	10. LOSS PER COMMON SHARE ​ Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted income per common share further includes any common shares available to be issued upon exercise of outstanding service-based stock options; exercise of outstanding performance-based stock options for which all performance conditions were satisfied; and satisfaction of all contingent consideration performance conditions; and RSAs and RSUs, if such inclusions would be dilutive. The potentially dilutive common shares are determined for inclusion in diluted income per common share using the treasury stock method. For periods of net loss, basic and diluted per common share information are the same. ​ The following table sets forth the computation of basic and diluted loss per common share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ ​ June 30, ​ June 30, ​ ​ 2019 2018 2019 2018 ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss ​ $ (159,462) ​ $ (3,964) ​ $ (173,763) ​ $ (4,414) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average common shares outstanding, basic ​ ​ 74,730,823 ​ ​ 74,158,622 ​ ​ 74,595,906 ​ ​ 74,077,916 ​ Weighted average dilutive effect of stock options, RSAs and RSUs ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Weighted average common shares outstanding, diluted ​ ​ 74,730,823 ​ ​ 74,158,622 ​ ​ 74,595,906 ​ ​ 74,077,916 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loss per common share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ $ (2.13) ​ $ (0.05) ​ $ (2.33) ​ $ (0.06) ​ Diluted ​ $ (2.13) ​ $ (0.05) ​ $ (2.33) ​ $ (0.06) ​ ​ The Company had a net loss for the three and six months ended June 30, 2019 and 2018. As a result, basic and diluted loss per common share were the same as any potentially dilutive securities would be anti-dilutive. In the absence of a net loss, the weighted average dilutive effect of stock options, RSUs and RSAs would have been 48,860 and 374,080 for the three months ended June 30, 2019 and 2018, respectively and 323,082 and 398,051 for the six months ended June 30, 2019 and 2018, respectively. ​ The weighted average effect of certain common stock equivalents including stock options, RSUs and RSAs were excluded from the computation of weighted average diluted shares outstanding as inclusion of such items would be anti-dilutive, are summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ June 30, ​ June 30, ​ 2019 2018 2019 2018 Service-based and earned performance-based stock options 3,896,446 4,032,813 3,753,244 4,022,012 Unearned performance-based stock options 574,138 574,138 574,138 ​ 574,138 Weighted average service-based RSUs 1,903,421 766,971 880,438 ​ 409,262 Weighted average performance based RSUs 467,308 770,859 — ​ 389,305 Weighted average RSAs 16,597 7,228 18,300 3,614 Total 6,857,910 6,152,009 5,226,120 5,398,331 ​

INCOME TAXES ​ The reconciliation of income taxes computed at the U.S. federal statutory tax rate to income tax expense is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ ​ June 30, ​ ​ 2019 2018 ​ Income tax benefit at U.S. statutory rate $ 36,269 ​ $ 744 ​ Tax effect from: ​ ​ ​ ​ ​ ​ ​ Valuation allowance ​ (32,423) ​ — ​ Share-based compensation ​ ​ (1,392) ​ ​ 542 ​ State income taxes, net of federal benefit ​ ​ (549) ​ ​ (763) ​ State income taxes, valuation allowance ​ ​ 62 ​ ​ — ​ Disallowed compensation ​ (161) ​ — ​ Non-deductible employee compensation in excess of $1,000 ​ ​ — ​ ​ (1,158) ​ Non-deductible goodwill impairment ​ ​ (2,645) ​ ​ — ​ Other ​ ​ (214) ​ ​ (236) ​ Income tax expense ​ $ (1,053) ​ $ (871) ​ ​ In determining the requirement for a valuation allowance against its deferred tax assets, the Company considers its historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset, along with other available positive and negative evidence. Due primarily to the parent company, along with several of its subsidiaries, being in a three-year cumulative loss from continuing operations position at June 30, 2019, the Company has determined it more likely than not its consolidated deferred tax asset and a substantial portion of separate entities’ deferred tax assets established for state loss carryforwards, will not be realized as a benefit in the future. Accordingly, the Company has increased its valuation allowance against these net deferred tax assets by $32,361 at June 30, 2019.

LEASES
LEASES	13. LEASES ​ The Company leases many of its pharmacy locations, office facilities, distribution centers, and certain office equipment through noncancelable operating lease contracts. Such noncancelable operating lease contracts convey the right to control such property for a period of time in exchange for consideration. The operating leases have initial terms ranging from three to 12 years and generally have options to extend for one or two five -year periods. Additionally, most frequently, the lease contracts include a provision for early termination after a specified time period along with payment of a termination fee. Beginning in 2019, the lease term, for accounting purposes, will include renewal option periods when it is reasonably certain that the option to extend the lease will be exercised based on the facts and circumstances at lease commencement. The lease agreements, most often, provide for rental payments that increase over the lease term based on a fixed percentage or specified amount. Additionally, the Company, in most cases, is required to pay real estate taxes, insurance costs and other occupancy costs such as common area maintenance that vary over the lease term. ​ Rent expense was $2,140 and $4,026 for the three and six months ended June 30, 2018. ​ The following table provides the components of lease expense for the three and six months ended June 30, 2019 in the Condensed Consolidated Statements of Comprehensive Loss, only the current year was impacted with the adoption of Topic 842: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ June 30, ​ June 30, ​ ​ 2019 ​ 2019 Operating lease cost $ 1,248 $ 3,307 Variable lease cost ​ ​ 814 ​ 1,191 Short-term lease cost ​ ​ 133 ​ 241 Total $ 2,195 ​ $ 4,739 ​ Maturities of lease liabilities for each of the next five years and thereafter, including reconciliation to the lease liabilities, were as follows: ​ ​ ​ ​ ​ 2019 (excluding the six months ended June 30, 2019) $ 3,077 2020 ​ ​ 5,751 2021 ​ ​ 5,029 2022 ​ 4,250 2023 ​ 3,214 Thereafter ​ 14,091 Total future lease payments ​ 35,412 Less: imputed interest costs (a) ​ (8,140) Lease liabilities $ 27,272 (a) Computed using the estimated incremental borrowing rate for each lease ​ Other information related to the Company's leases as of and for the six months ended June 30, 2019 is as follows: ​ ​ ​ ​ ​ ​ ​ Cash paid for amounts included in the measurement of lease liabilities ​ ​ Operating cash flows for operating leases ​ $ 3,307 Weighted average remaining lease term (in years) ​ 7.55 ​ Weighted average discount rate ​ 6.77 % ​

CONTINGENCIES	​ 14. CONTINGENCIES ​ On November 10, 2016, a putative class action complaint was filed in the U.S. District Court for the Eastern District of Michigan against Diplomat Pharmacy, Inc. and certain former officers of the Company. Following the appointment of lead plaintiffs and lead counsel, an amended complaint was filed on April 11, 2017. The amended complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with public filings made between February 29, 2016 and November 3, 2016 (the “potential class period”). The plaintiffs seek to represent a class of shareholders who purchased stock in the potential class period. The complaint seeks unspecified monetary damages and other relief. The Company filed a motion to dismiss the amended complaint on May 26, 2017. The court issued orders denying the Company’s motion to dismiss on January 19, 2018 and the Company’s motion for reconsideration of its motion to dismiss on August 9, 2018. The parties reached an agreement-in-principle on April 22, 2019 to resolve the litigation for a payment of $14,100 which is fully covered by the Company’s insurance policies. The court preliminarily approved the settlement on May 7, 2019, and a final settlement approval hearing is scheduled for August 20, 2019. If approved by the court, the settlement, given it is covered by the Company’s insurance policies, would not have a material impact on the Company’s results of operations, financial condition or cash flows. The Company has recorded the gross up ($14,100 insurance receivable in “Prepaid insurance and other current assets” and a $14,100 accrued liability included in “Accrued expenses – other”) of this settlement in the condensed consolidated balance sheet as of June 30, 2019. ​ On February 10, 2017, the Company’s Board of Directors received a demand letter from a purported shareholder containing allegations similar to those contained in the putative class action complaint described above. The letter demanded that the Board of Directors take action to remedy the alleged violations. In response, the Board of Directors established a Special Independent Committee of its disinterested and independent members to investigate the claims. Subsequently, on June 2, 2017, the shareholder filed a putative shareholder’s derivative lawsuit in the Michigan Circuit Court for the County of Genesee regarding the same matters alleged in the demand letter. The complaint named the Company as a nominal defendant and named a number of the Company’s current and former officers and directors as defendants. The complaint sought unspecified monetary damages and other relief. On February 6, 2019, the parties reached an agreement-in-principle to settle the action. On June 17, 2019, the court held the final settlement approval hearing and approved the settlement. The settlement did not have a material impact on the Company’s results of operations, financial condition or cash flows and was covered by the Company’s insurance policies. ​ On February 24, 2019 and March 6, 2019, in the U.S. District Court for the Central District of California and on March 12, 2019 in the U.S. District Court for the Northern District of Illinois, putative class actions complaints were filed against Diplomat Pharmacy, Inc. and certain current and former officers of the Company. The complaints alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with public filings made between February 26, 2018 and February 21, 2019 (the “potential class period”). The plaintiffs each sought to represent a class of shareholders who purchased stock in the potential class period. The complaints sought unspecified monetary damages and other relief. The cases were subsequently transferred and consolidated into a single proceeding in the Northern District of Illinois. The court appointed a lead plaintiff and lead counsel on July 19, 2019, and the lead plaintiff has sought leave until September 17, 2019 to file an amended complaint. The Company believes the complaints and allegations to be without merit and intends to vigorously defend itself against the action. The Company is unable at this time to determine whether the outcome of the litigation would have a material impact on its results of operations, financial condition or cash flows. ​ The Company’s business of providing specialized pharmacy services and other related services may subject it to litigation and liability for damages in the ordinary course of business. Nevertheless, the Company believes there are no other legal proceedings, the outcome of which, if determined adversely to the Company, would individually or in the aggregate be reasonably expected to have a material adverse effect on its business, financial position, cash flows, or results of operations.
