Simulations Plus, Inc.


November 30, 2017 and 2016



This report on Form 10-Q for the quarter ended November 30, 2017, should be read in conjunction with the Company's annual report on Form 10-K for the year ended August 31, 2017, filed with the Securities and Exchange Commission ("SEC") on November 14, 2017. As contemplated by the SEC under Article 8 of Regulation S-X, the accompanying consolidated financial statements and footnotes have been condensed and therefore do not contain all disclosures required by generally accepted accounting principles. The interim financial data are unaudited; however, in the opinion of Simulations Plus, Inc. ("we", "our", "us"), the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. Results for interim periods are not necessarily indicative of those to be expected for the full year.


Simulations Plus, Inc. ("Simulations Plus", "Lancaster") was incorporated on July 17, 1996. On September 2, 2014, Simulations Plus, Inc. acquired all of the outstanding equity interests of Cognigen Corporation ("Cognigen", "Buffalo") and Cognigen became a wholly owned subsidiary of Simulations Plus, Inc. Simulations Plus, Inc., acquired DILIsym Services, Inc. (DILIsym) as a wholly owned subsidiary pursuant to a stock purchase agreement dated May 1, 2017. On June 1, 2017, the Company consummated the acquisition of all outstanding equity interests of DILIsym pursuant to the terms of the Stock Agreement, with DILIsym becoming a wholly owned subsidiary of the Company. (Collectively, "Company", "we", "us", "our")

Lines of Business

The Company designs and develops pharmaceutical simulation software to promote cost-effective solutions to a number of problems in pharmaceutical research and in the education of pharmacy and medical students, and it provides consulting services to the pharmaceutical and chemical industries. Recently, the Company has begun to explore developing software applications for defense and for health care outside of the pharmaceutical industry.


Principles of Consolidation

The consolidated financial statements include the accounts of Simulations Plus, Inc. and, as of September 2, 2014, its wholly owned subsidiary, Cognigen Corporation, and as of June 1, 2017, the accounts of DILIsym Services, Inc. All significant intercompany accounts and transactions are eliminated in consolidation.


Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. These estimates and assumptions are affected by management's application of accounting policies. Actual results could differ from those estimates. Significant accounting policies for us include revenue recognition, accounting for capitalized computer software development costs, valuation of stock options, and accounting for income taxes.


Certain numbers in the prior year have been reclassified to conform to the current year's presentation.

Revenue Recognition

We recognize revenues related to software licenses and software maintenance in accordance with the FASB Accounting Standards Codification ("ASC") 985-605, "Software – Revenue Recognition" . Software product revenue is recorded when the following conditions are met: 1) evidence of arrangement exists; 2) delivery has been made; 3) the amount is fixed; and 4) collectability is probable. Post-contract customer support ("PCS") obligations are insignificant; therefore, revenue for PCS is recognized at the same time as the licensing fee, and the costs of providing such support services are accrued and amortized over the obligation period.


As a byproduct of ongoing improvements and upgrades for the new programs and new modules of software, some modifications are provided to our customers who have already purchased software at no additional charge. Other software modifications result in new, additional cost modules that expand the functionality of the software. These are licensed separately. We consider the modifications that are provided without charge to be minimal, as they do not significantly change the basic functionality or utility of the software, but rather add convenience, such as being able to plot some additional variable on a graph in addition to the numerous variables that had been available before, or adding some additional calculations to supplement the information provided from running the software. Such software modifications for any single product have typically occurred once or twice per year, sometimes more, sometimes less. Thus, they are infrequent. The Company provides, for a fee, additional training and service calls to its customers and recognizes revenue at the time the training or service call is provided.

Generally, we enter into one-year license agreements with customers for the use of our pharmaceutical software products. We recognize revenue on these contracts when all the criteria are met. Most license agreements have a term of one year; however, from time to time, we enter into multi-year license agreements. We generally unlock and invoice software one year at a time for multi-year licenses. Therefore, revenue is recognized one year at a time. Certain of the Company's software products are housed and supported on the Company's computer networks. Software revenues for those products are included in income over the life of the contract.

We recognize revenue on sales of our DILIsym Subsidiary in accordance with ASC 605-25, "Revenue Recognition, Multiple-Element Arrangements" . Our multiple-deliverable arrangements consist of consulting arrangements, at our DILIsym Subsidiary. We determined all elements to be separate units of accounting as they have standalone value to the customers. We allocate the revenue derived from these arrangements among all the deliverables. We base such allocation on the relative selling price of each deliverable. We recognize the allocated revenue for each deliverable when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed and determinable, and collectability is reasonably assured.

We recognize revenue from collaboration research, revenue from grants and consortium memberships over their terms. For contract revenues based on actual hours incurred, we recognize revenues when the work is performed. For fixed price contracts, we recognize contract study and other contract revenues using the percentage-of-completion method, depending upon how the contract studies are engaged, in accordance with ASC 605-35, " Revenue Recognition – Construction-Type and Production-Type Contracts" . To recognize revenue using the percentage-of-completion method, we must determine whether we meet the following criteria: 1) there is a long-term, legally enforceable contract, 2) it is possible to reasonably estimate the total project costs, and 3) it is possible to reasonably estimate the extent of progress toward completion.

Cash and Cash Equivalents

For purposes of the statements of cash flows, the Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Accounts Receivable

We analyze the age of customer balances, historical bad-debt experience, customer creditworthiness, and changes in customer payment terms when making estimates of the collectability of the Company's trade accounts receivable balances. If we determine that the financial conditions of any of its customers deteriorated, whether due to customer-specific or general economic issues, an increase in the allowance may be made. Accounts receivable are written off when all collection attempts have failed.

Capitalized Computer Software Development Costs

Software development costs are capitalized in accordance with ASC 985-20, "Costs of Software to Be Sold, Leased, or Marketed" . Capitalization of software development costs begins upon the establishment of technological feasibility and is discontinued when the product is available for sale.

The establishment of technological feasibility and the ongoing assessment for recoverability of capitalized software development costs require considerable judgment by management with respect to certain external factors including, but not limited to, technological feasibility, anticipated future gross revenues, estimated economic life, and changes in software and hardware technologies. Capitalized software development costs are comprised primarily of salaries and direct payroll-related costs and the purchase of existing software to be used in our software products.

Amortization of capitalized software development costs is calculated on a product-by-product basis on the straight-line method over the estimated economic life of the products (not to exceed five years). Amortization of software development costs amounted to $285,310 and $284,217 for the three months ended November 30, 2017 and 2016, respectively. We expect future amortization expense to vary due to increases in capitalized computer software development costs.


We test capitalized computer software development costs for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Property and Equipment

Property and equipment are recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful lives as follows:

Equipment 5 years
Computer equipment 3 to 7 years
Furniture and fixtures 5 to 7 years
Leasehold improvements Shorter of life of asset or lease

Maintenance and minor replacements are charged to expense as incurred. Gains and losses on disposals are included in the results of operations.

Goodwill and indefinite-lived assets

The Company performs valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and recognizes the assets acquired and liabilities assumed at their acquisition date fair value. Acquired intangible assets include customer relationships, software, trade names, and non-compete agreements. The Company determines the appropriate useful life by performing an analysis of expected cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over their estimated useful lives using the straight-line method, which approximates the pattern in which the majority of the economic benefits are expected to be consumed.

Goodwill represents the excess of the cost of an acquired entity over the fair value of the acquired net assets. Goodwill is not amortized, instead it is tested for impairment annually or when events or circumstances change that would indicate that goodwill might be impaired. Events or circumstances that could trigger an impairment review include, but are not limited to, a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of the Company's use of the acquired assets or the strategy for the Company's overall business, significant negative industry or economic trends, or significant under-performance relative to expected historical or projected future results of operations.

Goodwill is tested for impairment at the reporting unit level, which is one level below or the same as an operating segment. As of November 30, 2017, the Company determined that it has three reporting units, Simulations Plus, Cognigen Corporation, and DILIsym Services, Inc. When testing goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is necessary to perform step one of a two-step annual goodwill impairment test for each reporting unit. The Company is required to perform step one only if it concludes that it is more likely than not that a reporting unit's fair value is less than its carrying value. Should this be the case, the first step of the two-step process is to identify whether a potential impairment exists by comparing the estimated fair values of the Company's reporting units with their respective book values, including goodwill. If the estimated fair value of the reporting unit exceeds book value, goodwill is considered not to be impaired, and no additional steps are necessary. If, however, the fair value of the reporting unit is less than book value, then the second step is performed to determine if goodwill is impaired and to measure the amount of impairment loss, if any. The amount of the impairment loss is the excess of the carrying amount of the goodwill over its implied fair value. The estimate of implied fair value of goodwill is primarily based on an estimate of the discounted cash flows expected to result from that reporting unit, but may require valuations of certain internally generated and unrecognized intangible assets such as the Company's software, technology, patents, and trademarks. If the carrying amount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess.

As of November 30, 2017, the entire balance of goodwill was attributed to two of the Company's reporting units, Cognigen Corporation and DILIsym Services. Intangible assets subject to amortization are reviewed for impairment whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. There were no changes to goodwill, nor has the Company recognized any impairment charges, during the three months' periods ended November 30, 2017 and 2016.


Business Acquisitions

The Company accounted for the acquisition of Cognigen and DILIsym Services, Inc., using the purchase method of accounting where the assets acquired and liabilities assumed are recognized based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain acquired assets and liabilities is subjective in nature and often involves the use of significant estimates and assumptions, including, but not limited to, the selection of appropriate valuation methodology, projected revenue, expenses and cash flows, weighted average cost of capital, discount rates, estimates of advertiser and publisher turnover rates, and estimates of terminal values. Business acquisitions are included in the Company's consolidated financial statements as of the date of the acquisition.

Fair Value of Financial Instruments

Assets and liabilities recorded at fair value in the Condensed Balance Sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The categories, as defined by the standard are as follows:

Level Input: Input Definition:
Level I Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
Level II Inputs, other than quoted prices included in Level I, that are observable for the asset or liability through corroboration with market data at the measurement date.
Level III Unobservable inputs that reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date.

For certain of our financial instruments, including accounts receivable, accounts payable, accrued payroll and other expenses, accrued bonus to officer, and accrued warranty and service costs, the amounts approximate fair value due to their short maturities.

The following table summarizes fair value measurements at November 30, 2017 and August 31, 2017 for assets and liabilities measured at fair value on a recurring basis:

November 30, 2017:

Level 1 Level 2 Level 3 Total
Cash and cash equivalents $ 7,045,756 $ $ $ 7,045,756
Acquisition-related contingent consideration obligations $ $ $ 4,776,376 $ 4,776,376

August 31, 2017:

Level 1 Level 2 Level 3 Total
Cash and cash equivalents $ 6,215,718 $ $ $ 6,215,718
Acquisition-related contingent consideration obligations $ $ $ 4,738,188 $ 4,738,188

As of November 30, 2017 and August 31, 2017, the Company has a liability for contingent consideration related to its acquisition of the DILIsym Services, Inc. The fair value measurement of the contingent consideration obligations is determined using Level 3 inputs. The fair value of contingent consideration obligations is based on a discounted cash flow model using a probability-weighted income approach. These fair value measurements represent Level 3 measurements as they are based on significant inputs not observable in the market. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, changes in assumptions could have a material impact on the amount of contingent consideration expense the Company records in any given period. Changes in the value of the contingent consideration obligations are recorded in the Company's Consolidated Statement of Operations. 

The following is a reconciliation of contingent consideration value.

Value at August 31, 2017 $ 4,738,188
Contingent consideration payments
Change in value of contingent consideration 38,188
Value at November 30, 2017 $ 4,776,376


Research and Development Costs

Research and development costs are charged to expense as incurred until technological feasibility has been established. These costs include salaries, laboratory experiment, and purchased software which was developed by other companies and incorporated into, or used in the development of, our final products.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740-10, "Income Taxes" which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns.

Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities.

Intellectual property

On February 28, 2012, we bought out the royalty agreement with Enslein Research of Rochester, New York. The cost of $75,000 is being amortized over 10 years under the straight-line method. Amortization expense for each of the three-month periods ended November 30, 2017 and 2016 was $1,875. Accumulated amortization as of November 30, 2017 and August 31, 2017 was $43,125 and $41,250, respectively.

On May 15, 2014, we entered into a termination and nonassertion agreement with TSRL, Inc., pursuant to which the parties agreed to terminate an exclusive software licensing agreement entered into between the parties in 1997. As a result, the company obtained a perpetual right to use certain source code and data, and TSRL relinquished any rights and claims to any GastroPlus products and to any claims to royalties or other payments under that 1997 agreement. We agreed to pay TSRL total consideration of $6,000,000, which is being amortized over 10 years under the straight-line method. Amortization expense for each of the three-month periods ended November 30, 2017 and 2016 was $150,000. Accumulated amortization as of November 30, 2017 and August 31, 2017 was $2,125,000 and $1,975,000, respectively.

On June 1, 2017, as part of the acquisition of DILIsym Services, Inc. the Company acquired certain developed technologies associated with the drug induced liver disease (DILI). These technologies were valued at $2,850,000 and are being amortized over 9 years under the straight-line method. Amortization expense for the three months ended November 30, 2017 was $79,176 and is included in cost of revenues. Accumulated amortization as of November 30, 2017 and August 31, 2017 was $158,333 and $79,176, respectively.

Total amortization expense for intellectual property agreements for the three months ended November 30, 2017 and 2016 was $320,417 and $188,750, respectively. Accumulated amortization as of November 30, 2017 was $2,326,458 and $2,095,417 as of August 31, 2017.

Amortization expense for each of the three month periods ended November 30, 2017 and 2016 was $89,375 and $36,875, respectively. According to policy in addition to normal amortization, these assets are tested for impairment as needed.


Earnings per Share

We report earnings per share in accordance with FASB ASC 260-10. Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares available. Diluted earnings per share is computed similar to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. The components of basic and diluted earnings per share for the three months ended November 30, 2017 and 2016 were as follows:

Three months ended
11/30/2017 11/30/2016
Net income attributable to common shareholders $ 1,716,006 1,361,565
Weighted-average number of common shares outstanding during the period 17,282,132 17,226,192
Dilutive effect of stock options 589,551 182,942
Common stock and common stock equivalents used for diluted earnings per share 17,871,683 17,409,134

Stock-Based Compensation

Compensation costs related to stock options are determined in accordance with FASB ASC 718-10, "Compensation-Stock Compensation", using the modified prospective method. Under this method, compensation cost is calculated based on the grant-date fair value estimated in accordance with FASB ASC 718-10, amortized on a straight-line basis over the options' vesting period. Stock-based compensation was $130,221 and $95,860 for the three months ended November 30, 2017 and 2016, respectively. This expense is included in the condensed consolidated statements of operations as Selling, General, and Administration (SG&A), and Research and Development expense.

Impairment of Long-lived Assets

The Company accounts for the impairment and disposition of long-lived assets in accordance with ASC 350, "Intangibles – Goodwill and Other " and ASC 360, "Property and Equipment" . Long-lived assets to be held and used are reviewed for events or changes in circumstances that indicate that their carrying value may not be recoverable. We measure recoverability by comparing the carrying amount of an asset to the expected future undiscounted net cash flows generated by the asset. If we determine that the asset may not be recoverable, or if the carrying amount of an asset exceeds its estimated future undiscounted cash flows, we recognize an impairment charge to the extent of the difference between the fair value and the asset's carrying amount. No impairment losses were recorded during the three months ended November 30, 2017 and 2016.

Recently Issued Accounting Pronouncements

In May 2014, the Franchise Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). The standard will eliminate the transaction- and industry-specific revenue recognition guidance under current generally accepted accounting principles in the U.S. (GAAP) and replace it with a principles-based approach for determining revenue recognition. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for years beginning after December 15, 2016. The revenue recognition standard is required to be applied retrospectively, including any combination of practical expedients as allowed in the standard. We are evaluating the impact, if any, of the adoption of ASU 2014-09 to our financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. 

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the consolidated balance sheet. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.

In April 2016, the FASB issued AS 2016-10, Revenue from Contracts with Customers (Topic 606), which amends certain aspects of the Board's new revenue standard, ASU 2014-09, Revenue from Contracts with Customers. The standard should be adopted concurrently with adoption of ASU 2014-09 which is effective for annual and interim periods beginning after December 15, 2017. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

DILIsym Acquisition Liabilities :

On June 1, 2017, the Company acquired DILIsym Services, Inc. The agreement provided for a working capital adjustment, an eighteen-month $1,000,000 holdback provision against certain representations and warrantees, and an Earn-out agreement of up to an additional $5,000,000 in Earn-out payments based on earnings over the next three years. The Earn-out liability has been recorded at an estimated fair value. Payments under the Earn-out liability will be due starting in FY 2019, it is estimated that approximately 43% of the Earn-out liability and well as the holdback will be paid in 2019 and the majority of the remaining Earn-out will be paid in the following year.

As of November 30, 2017 and August, 31, 2017 the following liabilities have been recorded:

November 30,

We lease approximately 13,500 square feet of space in Lancaster, California. The original lease had a five-year term with two, three-year options to extend. The initial five-year term expired in February 2011, and we extended the lease to February 2, 2014. In June 2013, the lease was amended to extend the term to February 2, 2017. The amended lease also provides for an annual base rent increase of 3% per year and two, two-year options to extend. In May 2016 the Company exercised the two, two-year options extending the term of the lease through February 2, 2021 at a fixed rate of $25,000 per month. The new extension agreement allowed the Company with 90 days' notice to opt out of the remaining lease in the last two years of the term upon payment of a recapture payment equal to the 3% base payment increase that would have been due under the original agreement.

Our Buffalo subsidiary leases approximately 12,623 square feet of space in Buffalo, New York. The initial five-year term expires in October 2018; the lease allows for a three-year option to extend to October 2021. The current base rent is $15,638 per month.

In September 2017 DILIsym service signed a three-year lease for approximately 1,900 rentable square feet of space in Research Triangle Park, North Carolina. The initial three-year term expires in October 2020. The initial base rent is $3,975 per month with an annual 3% adjustment. Prior to this lease DILIsym was on a month-to-month rental.

Rent expense, including common area maintenance fees for the three months ended November 30, 2017, and 2016 was $135,877, and $122,949, respectively.


Employment Agreements

In the normal course of business, the Company has entered into employment agreements with certain of its key management personnel that may require compensation payments upon termination.

License Agreement

The Company executed a royalty agreement with Accelrys, Inc. ("Accelrys") (the original agreement was entered into with Symyx Technologies in March 2010; Symyx Technologies later merged with Accelrys, Inc.) for access to their Metabolite Database for developing our Metabolite Module within ADMET Predictor™. The module was renamed the Metabolism Module when we released ADMET Predictor version 6 on April 19, 2012. Under this agreement, we pay a royalty of 25% of revenue derived from the sale of the Metabolism/Metabolite module to Accelrys. In 2014, Dassault Systemes of France acquired Accelrys and the Company now operates under the name BIOVIA. We incurred royalty expense of $35,897 and $31,069, respectively, for the three months ended November 30, 2017 and 2016, respectively.

Income taxes

We follow guidance issued by the FASB with regard to our accounting for uncertainty in income taxes recognized in the financial statements. Such guidance prescribes a recognition threshold of more likely than not and a measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In making this assessment, a company must determine whether it is more likely than not that a tax position will be sustained upon examination, based solely on the technical merits of the position and must assume that the tax position will be examined by taxing authorities. Our policy is to include interest and penalties related to unrecognized tax benefits in income tax expense. Interest and penalties totaled $-0- for fiscal year 2018 We file income tax returns with the IRS and various state jurisdictions and India. Our federal income tax returns for fiscal year 2012 thru 2013 and 2015 are open for audit, and our state tax returns for fiscal year 2011 through 2015 remain open for audit. In addition, our California tax return for the fiscal year 2007 and fiscal year 2008 remains open with regard to R&D tax credits as a result of a previous audit for which we received a letter from the California Franchise Tax Board stating that an audit will not be conducted for those years at this time; however it may be subject to future audit.

Our review of prior year tax positions using the criteria and provisions presented in guidance issued by FASB did not result in a material impact on our financial position or results of operations.


From time to time, we may be involved in routine legal proceedings, as well as demands, claims and threatened litigation, which arise in the normal course of our business. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings, particularly complex legal proceedings, cannot be predicted with any certainty.

We are not a party to any legal proceedings and are not aware of any pending legal proceedings of any kind.

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, and trade accounts receivable. The Company holds cash and cash equivalents at banks located in California and North Carolina with balances that often exceed FDIC insured limits. Historically, the Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents. However, considering the current banking environment, the Company is investigating alternative ways to minimize its exposure to such risks. While the Company may be exposed to credit losses due to the nonperformance of its counterparties, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows, or financial condition. The Company maintains cash at financial institutions that may, at times, exceed federally insured limits. At November 30, 2017 the Company had cash and cash equivalents exceeding insured limits by $5,948,000.

Revenue concentration shows that international sales accounted for 35.6% and 31.8% of net sales for the three months ended November 30, 2017 and 2016, respectively. Four customers accounted for 7%, 7% (a dealer account in Japan representing various customers), 6% and 6% of net sales during the three months ended November 30, 2017. Three customers accounted for 9%, 7% (a dealer account in Japan representing various customers), and 6% of net sales during the three months ended November 30, 2016.

Accounts receivable concentration shows that six customers comprised 18%, 8%, 8% (a dealer account in Japan representing various customers), 7%, 6%, and 5% of accounts receivable at November 30, 2017. Accounts receivable concentration shows that four customers comprised 19%, 8% (a dealer account in Japan representing various customers), 7%, and 5% of accounts receivable at November 30, 2016.

We operate in the computer software industry, which is highly competitive and changes rapidly. Our operating results could be significantly affected by our ability to develop new products and find new distribution channels for new and existing products.

The majority of our customers are in the pharmaceutical industry. Consolidation and downsizing in the pharmaceutical industry could have an impact on our revenues and earnings going forward.

DILIsym Services, Inc.

On May 1, 2017, the Company entered into a Stock Purchase Agreement (the "Stock Agreement") with DILIsym Services, Inc ("DILIsym"). On June 1 2016, the Company consummated the acquisition of all outstanding equity interests of DILIsym pursuant to the terms of the Stock Agreement, with DILIsym becoming a wholly owned subsidiary of the Company. We believe the combination of Simulations Plus and DILIsym provides substantial future potential based on the complementary strengths of each of the companies.

Under the terms of the Stock Agreement, as described below, the Company will pay the former shareholders of DILIsym total consideration of approximately $10,463,000.

On June 1, 2017, the Company paid the former shareholders of DILIsym a total of $4,515,982, which included a $4,000,000 initial payment and a preliminary working capital payment of $515,982. Additional working capital adjustments of $247,328 were due under the agreement and were paid subsequent to August 31, 2017.

Within three business days following the eighteen-month anniversary of the date of the Stock Agreement, May 1, 2017, and subject to any offsets, the Company will pay the former shareholders of DILIsym a total of $1,000,000. The agreement calls for Earn-out payments up to an additional $5,000,000 based on a formula of pre-tax earnings over the next three years. The Earn-out liability has been recorded at fair value.

Under the acquisition method of accounting, the total estimated purchase price is allocated to DILIsym's tangible and intangible assets and liabilities based on their estimated fair values at the date of the completion of the acquisition (June 1, 2017). The following table summarizes the preliminary allocation of the purchase price for DILIsym:

Assets acquired, including accounts receivable of $255,000 and estimated Contracts receivable of $153,000 $ 2,283,110
Developed Technologies Acquired 2,850,000
Estimated value of Intangibles acquired (Customer Lists, trade name etc.) 2,840,000
Current Liabilities assumed (911,049 )
Goodwill 5,597,950
Estimated Deferred income taxes (2,212,160 )
Total Consideration $ 10,463,310


Goodwill has been provided in the transaction based on estimates of future earnings of this subsidiary including anticipated synergies associated with the positioning of the combined company as a leader in model-based drug development. Based on the structure of the transaction, the Company does not anticipate benefiting from any tax deductions in future periods for recognized goodwill.


Consolidated supplemental Pro Forma information

The following consolidated supplemental pro forma information assumes that the acquisition of DILIsym took place on September 1, 2016 for the income statement for the three-month period ended November 30, 2016. These amounts have been calculated after applying the Company's accounting policies and adjusting the results of DILIsym to reflect the same expenses in the three-month period ended November 30, 2016. The adjustments include costs of acquisition, and amortization of intangibles and other technologies acquired during the merger, assuming the fair-value adjustments applied on September 1, 2016, together with consequential tax effects.

On December 22, 2017, the U.S. President signed the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act). Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 740, Income Taxes ("ASC 740") requires that the company recognize the effects of changes in tax laws or tax rates in the financial statements for the period in which such changes were enacted. Among other things, changes in tax laws or tax rates can affect the amount of taxes payable for the current period, as well as the amount and timing of deferred tax liabilities and deferred tax assets. The Company is a fiscal year reporting company, because the 2017 Tax Act became law in December 2017, and as such would be required to account for the impacts related to the 2017 Tax Act in the financial statements included in their annual report on Form 10-K for August 31, 2018 due in November 2018. The Company has elected to take advantage of the extended measurement period provided by SEC Staff Accounting Bulletin No. 118, and will report the effect of the changes from the 2017 Tax Act when the calculations are complete, or reasonable estimates can be determined. The Company has begun the process of analysis of the 2017 Tax Act and will recognize the effect of the changes in tax laws or rates in the period that the process has been completed.

The difference between DILIsym and NAFLDsym is that DILIsym estimates the potential for a particular drug molecule to induce liver injury (i.e., to cause damage), while NAFLDsym estimates the likelihood of new molecules to treat nonalcoholic fatty liver disease (i.e., to repair damage), and is unique to the mechanisms involved in such treatment. As such, DILIsym can be a single program that addresses a wide variety of molecules across various companies, while NAFLDsym requires customizing the software for each mechanism of action. Both the DILIsym and NAFLDsym software programs require outputs from physiologically based pharmacokinetics (PBPK) software as inputs. The GastroPlus™ PBPK software from Simulations Plus provides such information; thus, the integration of these technologies will provide a seamless capability for analyzing the potential for drug-induced liver injury for new drug compounds and for investigating the potential for new therapeutic agents to treat nonalcoholic fatty liver disease.

We are a global leader focused on improving the ways scientists use knowledge and data to predict the properties and outcomes of pharmaceutical and biotechnology agents, and are one of only two global companies who provide a wide range of preclinical and clinical consulting services and software. Our innovations in integrating new and existing science in medicinal chemistry, computational chemistry, pharmaceutical science, biology, physiology, and machine learning into our software have made us the leading software provider for PBPK modeling and simulation and for prediction of molecular properties from structure.

We generate revenue by delivering relevant, cost-effective software and creative and insightful consulting services. Pharmaceutical and biotechnology companies use our software programs and scientific knowledge to guide early drug discovery (molecule design and screening), preclinical, and clinical development programs. They also use it to enhance their understanding of the properties of potential new medicines and to use emerging data to improve formulations, select and justify dosing regimens, support the generics industry, optimize clinical trial designs, and simulate outcomes in special populations, such as the elderly and pediatric patients.



We currently offer ten software products for pharmaceutical research and development: five simulation programs that provide time-dependent results based on solving large sets of differential equations: GastroPlus™; DDDPlus™; MembranePlus™; DILIsym®; and NAFLDsym™; three programs that are based on predicting and analyzing static (not time-dependent) properties of chemicals: ADMET Predictor™; MedChem Designer™; and MedChem Studio™ (the combination of ADMET Predictor, MedChem Designer, and MedChem Studio is called our ADMET Design Suite™); our newest program which is designed for rapid clinical trial data analysis and regulatory submissions called PKPlus™; and a program called KIWI™ from our Cognigen division that provides an integrated platform for data analysis and reporting through our proprietary secure cloud.


Our flagship product, and currently our largest single source of software revenue, is GastroPlus. GastroPlus simulates the absorption, pharmacokinetics, and pharmacodynamics of drugs administered to humans and animals, and is currently the most widely used commercial software of its type by pharmaceutical companies, the U.S. Food and Drug Administration (FDA), the U.S. National Institutes of Health (NIH), and other government agencies in the U.S. and other countries. The FDA currently has 30 floating GastroPlus licenses shared across various divisions.

Because of the widespread use of GastroPlus, we were the only non-European company invited to join the European Innovative Medicines Initiative (IMI) program for Oral Bioavailability Tools (OrBiTo). OrBiTo, begun in 2012 and completed in 2017, was an international collaboration among 27 industry, academic, and government organizations working in the area of oral absorption of pharmaceutical products. Because we are outside of the European Union, our participation in this project was at our own expense, while other members were compensated for their work; however, we were a full member with access to all of the data and discussions of all other members. We believe our investment to participate in this initiative enabled us to benefit from, and to contribute to, advancing the prediction of human oral bioavailability from preclinical data, and ensured that we are well-known to member pharmaceutical companies and regulatory agencies.


In September 2016, we announced that Simulations Plus had been invited to join the European SimInhale Consortium and had been admitted to this prestigious group focused on advancing the state of the art for simulation of inhaled dosage forms. As one of only two U.S. participants, Simulations Plus is participating in activities designed to advance particle designs for improved deposition and interaction with lung tissue; promote realistic computer simulations of particle aerosolization, delivery, and deposition; promote patient-tailored inhaled medicines; promote integration of device and formulation design; and promote critical assessment of toxicity issues and related risks.

In September 2014, we entered into a research collaboration agreement (RCA) with the FDA to enhance the Ocular Compartmental Absorption and Transit (OCAT™) model within the Additional Dosing Routes Module of GastroPlus. The objective of this agreement was to provide a tool for generic companies and the FDA to assess the likely bioequivalence of generic drug formulations dosed to the eye. Under this RCA, we received up to $200,000 per year. This RCA could be renewed for up to a total of three years based on the progress achieved during the project. After a successful second year, the RCA was renewed for its third year in September 2016, and was completed in September 2017.

We were awarded another RCA by the FDA in September 2015; this one to expand the capabilities of GastroPlus to simulate the dosing of long-acting injectable microspheres. This type of dosage form is usually injected via subcutaneous or intramuscular routes, but can also be used for ocular dosing. Once again, this RCA provides up to $200,000 per year for up to three years. Under this agreement, we are developing simulation models to deal with the very slow dissolution/decomposition of the microsphere carrier material that gradually releases the active drug over periods as long as weeks or months. After a successful second year, the RCA was renewed for the third year in September 2017, and will expire in September 2018 unless further renewed.

In addition to the two funded efforts with the FDA described above, we also have an unfunded RCA with the FDA's Office of Generic Drugs (OGD) that began in 2014. The objective of this RCA, which has a five-year term, is directed toward the FDA's evaluation of mechanistic IVIVCs ( in vitro-in vivo correlations) to determine whether mechanistic absorption modeling (MAM) can relate laboratory ( in vitro ) dissolution experiment results to the behavior of dosage forms in humans and animals ( in vivo ) better than traditional empirical methods.

In April 2017, we released Version 9.5 of GastroPlus after nearly two years of improvements over version 9.0, which was released in April 2015. Version 9.5 is now the largest single upgrade we've made to the program. New functionalities that we believe provide the most advanced decision-making tool for preclinical and early clinical trial simulation and modeling analysis available today include:

· ability to simulate the absorption and distribution of antibody-drug conjugates (ADCs), which are antibodies that are used to carry small drug molecules to the intended target tissue
· ability to dose via intramuscular injection and an improved model for subcutaneous injection
· several new physiology models, including Chinese and hepatic impairment populations
· revamped workflows for building in vitro-in vivo correlations (IVIVCs) and performing virtual bioequivalence trial simulations
· improved reporting capabilities, making it easier for companies wishing to submit results to regulatory agencies

Our goal with GastroPlus is to integrate the most advanced science into user-friendly software to enable pharmaceutical researchers and regulators to perform sophisticated analyses of complex drug behaviors in humans and laboratory animals. Already the most widely used program in the world for physiologically based pharmacokinetics (PBPK), the addition of these new capabilities is expected to expand the user base in the early pharmaceutical research and development process, while also helping us further penetrate the biopharmaceuticals, food, cosmetics, and general toxicology markets.

Version 9.6 is now in development and release is expected in early calendar 2018. This version will add a number of important new capabilities, including improvements to absorption, metabolism, drug-drug interaction, and output reporting, among others.


DDDPlus simulates in vitro (laboratory) experiments that measure the rate of dissolution of a drug and, if desired, the additives (excipients) in a particular dosage form (e.g., powder, tablet, capsule, or injectable solids) under a variety of experimental conditions. This unique software program is used by formulation scientists in industry and the FDA to (1) understand the physical mechanisms affecting the disintegration and dissolution rates of various formulations, (2) reduce the number of cut-and-try attempts to design new drug formulations, and (3) design in vitro dissolution experiments to better mimic in vivo (animal and human) conditions. Version 5.0 of DDDPlus, which added a number of significant enhancements, was released in April 2016. This version added new formulation types (controlled release bilayer tablet, delayed release coated tablet, and immediate release coated beads), expanded formulation specification options, biorelevant solubilities and surfactant effects on dissolution, tablet compression and disintegration models, links with GastroPlus, and updated licensing. Current improvements in development and testing include new capabilities to simulate in vitro dissolution experiments for long-acting injectable microspheres as part of our work under the FDA-funded grant mentioned above.


Version 6.0 of DDDPlus is in final development testing and will offer a series of new capabilities, including:

· simulation of the in vitro dissolution of long-acting injectable dosage forms

· simulation of the in vitro dissolution of controlled release bead formulations

· improved simulation of transfer assay experiments

· ability to fit models from precipitation experiments

· new dissolution apparatus models

· improved output reporting


MembranePlus was released in October 2014. Similar to DDDPlus, MembranePlus simulates laboratory experiments, but in this case, the experiments are for measuring permeability of drug-like molecules through various membranes, including several different standard cell cultures (Caco-2, MDCK), as well as artificially formulated membranes (PAMPA). The value of such simulations derives from the fact that when the permeabilities of the same molecules are measured in different laboratories using (supposedly) the same experimental conditions, the results are often significantly different. These differences are caused by a complex interplay of factors in how the experiment was set up and run. MembranePlus simulates these experiments with their specific experimental details, and this enables scientists to better interpret how results from specific experimental protocols can be used to predict permeability in human and animals, which is the ultimate goal.

Version 2.0 of MembranePlus is in final development testing. This version will add:

· simulation of sandwich hepatocyte assays

· simulation of suspended hepatocyte assays

· intracellular protein binding

· integration of ADMET Predictor metabolism predictions

· improved output reporting


On August 25, 2016, we announced the release of a new standalone software product called PKPlus, based on the internal PKPlus Module in GastroPlus that has been available since 2000. The PKPlus Module in GastroPlus provides quick and easy fitting of compartmental pharmacokinetic (PK) models as well as a simple noncompartmental analysis (NCA) for intravenous and extravascular (oral, dermal, ocular, pulmonary, etc.) doses; however, the PKPlus Module in GastroPlus was not designed to meet all of the requirements for performing these analyses for Phase 2 and 3 clinical trials, nor to produce report-quality output for regulatory submissions. The new standalone PKPlus program has been developed to provide the full level of functionality needed by pharmaceutical industry scientists to perform the analyses and generate the outputs needed to fully satisfy regulatory agency requirements for both more complex NCA as well as compartmental PK modeling. After receiving considerable feedback on version 1.0, we began modifying the program to include a number of additional features requested by our users and potential users and expect to release the next version early in 2018. We believe the potential number of eventual users for PKPlus is in the thousands world-wide and that it has the potential to eventually become one of our leading revenue producers.

We are now in final development testing and documentation of PKPlus version 2.0, which has incorporated a wide variety of requested features from current users as well as evaluators of version 1.0, including:

· 21 CFR Part 11 compliance for audit trail and validation

· nonparametric superstition for analysis of multiple-dose pharmacokinetics


· ability to edit input data prior to incorporating it into a project

· ability to save templates for various types of analyses to reduce the time required when working with new datasets

· new statistics graphical outputs

· command line capability for rapid validation after installation on customers' computer systems and for batch processing

ADMET Predictor™

ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) Predictor is a chemistry-based computer program that takes molecular structures (i.e., drawings of molecules represented in various formats) as inputs and predicts approximately 150 different properties for them at an average rate of over 100,000 compounds per hour on a modern laptop computer. This capability allows chemists to generate estimates for a large number of important molecular properties without the need to synthesize and test the molecules, as well as to generate estimates of unknown properties for molecules that have been synthesized, but for which only a limited number of experimental properties have been measured. Thus, a chemist can assess the likely success of a large number of existing molecules in a company's chemical library, as well as molecules that have never been made, by providing only their molecular structures, either by drawing them using a tool such as our MedChem Designer software, or by automatically generating large numbers of molecules using various computer algorithms, including those embedded in our MedChem Studio software.

ADMET Predictor has enjoyed top-ranked for predictive accuracy in multiple peer-reviewed, independent comparison studies for many years, while generating its results at a high throughput rate. Although the state of the art of this type of software does not enable identifying the best molecule in a series, it does allow early screening of molecules that are highly likely to fail as potential drug candidates (i.e., the worst molecules, which is usually the majority of a chemical library) before synthesizing and testing them. Thus, millions of virtual compounds can be created and screened in a day, compared to potentially months or years of work to actually synthesize and test a much smaller number of actual compounds.

ADMET Predictor version 8.0 was released on August 1, 2016. This version featured a completely redesigned and modernized interface as well as a number of new capabilities to enhance the performance and user-friendliness of the program. In addition, we integrated a number of MedChem Studio features into version 8.0, and created a tighter integration between the two programs when a MedChem Studio license is obtained along with an ADMET Predictor license.

The optional ADMET Modeler Module™ in ADMET Predictor enables scientists to use their own experimental data to quickly create proprietary high-quality predictive models using the same powerful machine-learning methods we use to build our top-ranked property predictions. Pharmaceutical companies expend substantial time and money conducting a wide variety of experiments on new molecules each year, generating large databases of experimental data. Using this proprietary data to build predictive models can provide a second return on their investment; however, model building has traditionally been a difficult and tedious activity performed by specialists. The automation in ADMET Modeler makes it easy for a scientist to create very powerful models with minimal training.

We released version 8.1 of ADMET Predictor in January 2017. This release included:

· both 64-bit and 32-bit executables, making it possible to handle larger data sets
· optimization of spreadsheet and model-building functions to improve efficiency
· streamlined and much more efficient model-building in ADMET Modeler  using our proprietary machine-learning engine
· combinatorial substituent and scaffold replacement operations in the MedChem Studio™ Module
· new in silico Ames tests to produce reliable confidence predictions that are more broadly applicable
· ADMET Risk™ scores accessible graphically in histograms

The recent release of version 8.5 in November 2017 added:

· a new Simulation Module to predict absorption and bioavailability for libraries of molecules from their structure

· ability to optimize doses to achieve desired steady-state concentrations

· new property models for rat fraction unbound in plasma, blood/plasma concentration ratio, and metabolism by certain enzymes


· all MedChem Studio™ features now available through the same graphical user interface as ADMET Predictor

· new synthetic difficulty model

· improved visualization

· multithreading and other speed enhancements

Potential new markets for machine learning

We are currently investigating applications of our sophisticated machine-learning engine outside of our normal pharmaceutical markets. To date, we have conducted several proof-of-concept studies including: (1) building predictive models for missile aerodynamic force and moment coefficients as a function of missile geometry, Mach number, and angle of attack, (2) classifying/identifying missiles and other objects from radar tracking data, (3) mapping jet engine compressor performance to predict when maintenance might be required, and (4) classifying patients as healthy or experiencing some disease state or genetic disorder evidenced by magnetic resonance imaging (MRI) of the brain. Other potential applications for this modeling engine have also been identified; however, our focus to date has been primarily in these areas.

We believe our proprietary machine-learning software engine has a wide variety of potential applications and we intend to pursue funding to develop customized tools to further monetize our investment in this technology by expanding our markets beyond the life sciences and chemistry. In addition, we are examining a variety of expanded capabilities to add to the basic modeling engine to accommodate even larger data sets ("big data analytics") and new applications.

MedChem Designer™

MedChem Designer was launched in 2011. It was initially a molecule-drawing program, or "sketcher", but now has capabilities exceeding those of other molecule-drawing programs because of its integration with both MedChem Studio and ADMET Predictor. We provide MedChem Designer for free because we believe that in the long run it will help to increase demand for ADMET Predictor and MedChem Studio, and because most other existing molecule-drawing programs are also provided for free. Our free version includes a small set of ADMET Predictor's best-in-class property predictions, allowing the chemist to modify molecular structures and then see a few key properties very quickly. With a paid ADMET Predictor license, the chemist would see the entire approximately 150 predictions that are available. Over 23,000 copies of MedChem Designer have been downloaded by scientists around the world to date.

When used with a license for ADMET Predictor, MedChem Designer becomes a de novo molecule design tool. With it, a researcher can draw one or more molecular structures, then click on the ADMET Predictor icon and have approximately 150 properties for each structure calculated in seconds, including our proprietary ADMET Risk index. Researchers can also click on an icon to generate the likely metabolites of a molecule and then predict all of the properties of those metabolites from ADMET Predictor, including each of their ADMET Risk scores. This is important because a metabolite of a molecule can be therapeutically beneficial (or harmful) even though the parent molecule is not.

Our proprietary ADMET Risk score provides a single number that tells the chemist how many default threshold values for various predicted properties were crossed (or violated) by each structure. Thus, in a single number, the chemist can instantly compare the effects of different structural changes in many dimensions. The ideal score is zero; however, a low score greater than zero might be acceptable, depending on what property(s) caused the points to be assigned. If the number is too high (greater than 5 or 6), the molecule is not likely to be successful as a drug. The default rules can be modified and new rules can be added by the user to include any desired rule set based on any combination of calculated descriptors, predicted properties, and user inputs. As chemists attempt to modify structures to improve one property, they often cause others to become unacceptable. Without ADMET Risk, the chemist would have to individually examine many key properties for each new molecule (and its metabolites) to determine whether any of them became unacceptable as a result of changing the structure.

MedChem Studio™

MedChem Studio has been integrated into the ADMET Predictor platform, but can still be licensed separately without requiring a license for ADMET Predictor. MedChem Studio is a powerful software tool that is used both for data mining and for de novo design of new molecules. In its data-mining role, MedChem Studio facilitates searching large chemical libraries to find molecules that contain identified substructures, and it enables rapid identification of clusters (classes) of molecules that share common substructures. We have now merged MedChem Studio with ADMET Predictor so that either program can be entered through the same interface, and the communication between the two programs is enhanced through the seamless integration of both technologies. We believe this will enhance the attractiveness of both ADMET Predictor and MedChem Studio to medicinal and computational chemists.


While MedChem Designer can be used to refine a small number of molecules, MedChem Studio can be used to create and screen (with ADMET Predictor) very large numbers of molecules down to a few promising lead candidates. MedChem Studio has features that enable it to generate new molecular structures using a variety of de novo design methods. When MedChem Studio is used with ADMET Predictor and MedChem Designer (the combination of which we refer to as our ADMET Design Suite), we believe the programs provide an unmatched capability for chemists to search through large libraries of compounds that have undergone high-throughput screening experiments to find the most promising classes (groups of molecules with a large common part of their structures) and molecules that are active against a particular target. In addition, MedChem Studio can take an interesting (but not acceptable) molecule and, using a variety of design algorithms, quickly generate many thousands to millions of high quality analogs (similar new molecules). These molecules can then be screened using ADMET Predictor to find molecules that are predicted to be both active against the target and acceptable in a variety of ADMET properties. We demonstrated the power of the ADMET Design Suite during two NCE (new chemical entity) projects wherein we designed lead molecules to inhibit the growth of the plasmodium falciparum malaria parasite in one study, and lead molecules that were able to inhibit two targets at the same time: COX-1 and COX-2. In each case, we announced ahead of time that we were attempting to do this, and we reported the results when the projects were complete. Every molecule we designed and had synthesized hit their targets in both projects, clearly demonstrating the power of the ADMET Design Suite.


Drug development programs rely increasingly on modeling and simulation analyses to support decision-making and submissions to regulatory agencies. To ensure high-quality analyses, organizations must not only apply high-quality science, but must also be able to support the science by being able to validate the results. KIWI is a cloud-based web application that was developed to efficiently organize, process, maintain, and communicate the volume of data and results generated by pharmacologists and scientists over the duration of a drug development program. The validated workflow and tools within KIWI promote traceability and reproducibility of results.

The pharmaceutical industry has been rapidly adopting cloud technology as a solution to ever-expanding computer processing needs. Leveraging our 20-plus years of experience in providing an architecture supporting modeling and simulation efforts, we have developed KIWI as a secure, validated, enterprise-scale environment, enabling global teams to collaborate on model-based decision making. KIWI has proven to be a valuable platform for encouraging interdisciplinary discussions about the model development process and interpretation of results. We continue to receive positive feedback about the functionality implemented in KIWI and the value of the approach we have taken to harness cloud technology. We continue to improve functionality and collaboration within the KIWI platform, and we expect the licensing fee will be a source of recurring revenue for further development and growth. KIWI Version 1.3 was released in May 2015. This version of KIWI provides our user community with access to new features that accelerate completion of modeling projects by decreasing run times and facilitating the comparison and exporting of results across models. These features include dynamic comparisons of model parameter estimates and diagnostic plots, export of model run records for regulatory submissions, and accelerated infrastructure with the upgrade to the latest versions of NONMEM® and Perl-speaks-NONMEM running in a 64-bit Linux environment.

KIWI Version 1.6 was released in September 2016. This new version introduced major enhancements in the functionality of visualization tools offered by the platform. These enhancements include simplifying the creation of plots and comparing them across multiple models, thus accelerating the model refinement process. In addition, analysts can now conveniently copy visualization preferences across projects, improving consistency and facilitating collaboration and communication with clients and colleagues.

KIWI 2 was released in December 2017. This latest version introduces a repository within the KIWI Cloud service to facilitate the management and organization of data and documents used and produced to support the modeling and simulation analyses used, in part, to submit new drug applications. The user interface provides a pre-defined directory as a default that can be customized, allows file version control, and provides a comprehensive roles and permissions structure to enhance collaboration among a community of users. As part of this initiative an enhanced authentication framework foundation was included to provide the ability for clients to customize authentication rules according to their internal regulatory policies and procedures. In addition, since it can take hundreds of models to create one final model, an automated diagnostics dashboard has been added that visually displays the results of over 10 diagnostics that are used by modelers to decide what direction to take their modeling with the potential to significantly reduce the amount of time it takes to arrive at a final model.

We continue enhancing KIWI as part of our five-year, almost-$5 million contract with a leading global research foundation.



The DILIsym software is a quantitative systems pharmacology (QSP) program that has been in development since 2011. QSP software models are based on the fundamental understanding of complex biological pathways, disease processes, and drug mechanisms of action, integrating information from experiments and forming hypotheses for the next experimental model. DILIsym deals with the propensity for some drug molecules to induce temporary or permanent changes in biological functions within liver cells (hepatocytes) that can result in damage to the liver. Some drugs cause temporary changes in liver function but the body soon compensates and liver function returns to normal. Other drugs cause liver function to permanently decline as they continue to be taken. The DILIsym software models a variety of interactions within the hepatocytes to determine whether a particular drug molecule interrupts normal signaling pathways in a manner to induce injury to the cells.


Where DILIsym is used to investigate the likelihood that a known drug molecule would cause injury to the liver, NAFLDsym is concerned with a liver that is already diseased by excess fat and investigates the likelihood that various molecules might provide beneficial therapeutic benefits to treat or cure the disease. DILIsym can be considered a "shrink wrap" software product, usable across many companies and drug development projects. NAFLDsym, on the other hand, requires modification for each of a number of different mechanisms of action that potential new drug compounds could use to treat the disease, and so is a customized tool used in consulting projects for each new client project.

Contract Research and Consulting Services

Our scientists and engineers have expertise in drug absorption via various dosing routes (oral, intravenous, subcutaneous, intramuscular, ocular, nasal/pulmonary, and dermal), pharmacokinetics, and pharmacodynamics. They have attended over 200 scientific meetings worldwide in the past four years, often speaking and presenting. We frequently conduct contracted consulting studies for large customers (including the five largest pharmaceutical companies) who have particularly difficult problems and who recognize our expertise in solving them, as well as for smaller customers who prefer to have studies run by our scientists rather than to license our software and train someone to use it. The demand for our consulting services has been steadily increasing, and we have expanded our consulting teams to meet the increased workload.

We continue working on a five-year consulting agreement with a major research foundation to implement a platform for coordinating the data generated by global teams engaged in model-based drug development.

We currently are working with the FDA on two Research Collaboration Agreements (RCAs): the funded efforts for long-acting injectable microspheres and the unfunded IVIVC effort, both described above under "GastroPlus". We also successfully completed the third year of our funded collaboration for ocular dosing just after the end of FY2017.

Pharmacometric Modeling

We have a reputation for high-quality analyses and regulatory reporting of data collected during preclinical experiments as well as clinical trials of new and existing pharmaceutical products, typically working on 30-40 drug projects per year. Traditionally, the model-based analysis of clinical trial data was different from the modeling analysis offered by GastroPlus; the former relied more on statistical and semi-mechanistic models, whereas the latter is based on very detailed mechanistic models. Statistical models rely on direct observation and mathematical equations that are used to fit data collected across multiple studies along with describing the variability within and between patients. Mechanistic models are based on a detailed understanding of the human body and the chemistry of the drug and involve mathematical and scientific representation of the phenomena involved in drug dissolution/precipitation, absorption, distribution, metabolism, and elimination. Collectively, the models guide drug formulation design and dose selection. Beginning in 2014, the U.S. F.D.A and other regulatory agencies began to emphasize the need to push mechanistic PBPK modeling and simulation into clinical pharmacology, and we have seen the benefit of having our clinical pharmacology team in the Cognigen division and our scientists in our Lancaster, California (Simulations Plus) division working together to achieve this goal.


Development of our software is focused on expanding product lines, designing enhancements to our core technologies, and integrating existing and new products into our principal software architecture and platform technologies. We intend to continue to offer regular updates to our products and to continue to look for opportunities to expand our existing suite of products and services.


To date, we have developed products internally, sometimes also licensing or acquiring products, or portions of products, from third parties. These arrangements sometimes require that we pay royalties to third parties. We intend to continue to license or otherwise acquire technology or products from third parties when it makes business sense to do so. We currently have one license agreement, with BIOVIA (formerly known as Accelrys, Inc.), a San Diego division of Dassault Systemes in France, pursuant to which a small royalty is paid to BIOVIA from revenues on each license for the Metabolite module in ADMET Predictor. This license agreement continues in perpetuity and either party has the right to terminate it.

In 1997 we entered into an exclusive software licensing agreement with TSRL, Inc. (aka Therapeutic Systems Research Laboratories) (TSRL), pursuant to which TSRL licensed certain software technology and databases to us, and we paid royalties to TSRL. On May 15, 2014, we and TSRL entered into a termination and nonassertion agreement pursuant to which the parties agreed to terminate the 1997 exclusive software licensing agreement. As a result, the Company obtained a perpetual right to use certain source code and data, and TSRL relinquished any rights and claims to any GastroPlus products and to any claims to royalties or other payments under that agreement, and we agreed to pay TSRL total consideration of $6,000,000. All payments have now been made as of April 2017. Our payment obligation is being amortized at a constant rate of $150,000 per quarter until it is completely amortized, after which no further expense will be incurred. To date, this has resulted in expense savings over $950,000 compared to the royalty payments that would have been paid to TSRL if paid consistent with past practices.


We distribute our products and offer our services in North America, South America, Europe, Japan, Australia, New Zealand, India, Singapore, Taiwan, and the People's Republic of China.

We market our pharmaceutical software and consulting services through attendance and presentations at scientific meetings, exhibits at trade shows, seminars at pharmaceutical companies and government agencies, through our website, and using various communication channels to our database of prospects and customers. At various scientific meetings around the world each year there are numerous presentations and posters presented in which the reported research was performed using our software. Many of these presentations are from industry and FDA scientists; some are from our staff. In addition, more than 50 peer-reviewed scientific journal articles, posters, and podium presentations are typically published each year using our software, mostly by our customers, further supporting its use in a wide range of preclinical and clinical studies.

Our sales and marketing efforts are handled primarily internally with our scientific team and several senior management staff assisting our marketing and sales staff with trade shows, seminars, and customer trainings both online and on-site. We believe that this is more effective than a completely separate sales team for several reasons: (1) customers appreciate talking directly with software developers and consulting scientists who can answer a wide range of in-depth technical questions about methods and features; (2) our scientists and engineers gain an appreciation for the customer's environment and problems; and (3) we believe the relationships we build through scientist-to-scientist contact are stronger than relationships built through salesperson-to-scientist contacts. We also have one independent distributor in Japan and two independent representatives in China who also sell and market our products with support from our scientists and engineers.

We provide support to the GastroPlus User Group in Japan, which was organized by Japanese researchers in 2009. In early 2013, a group of scientists in Europe and North America organized another GastroPlus User Group following the example set in Japan. Nearly 1,000 members have joined this group to date. We support this group through coordination of online meetings each month and managing the user group web site for exchange of information among members. These user groups provide us valuable feedback with respect to desired new features and suggested interface changes.


Our pharmaceutical software products are designed and developed by our development teams in California (Lancaster, Guerneville, San Jose, and San Diego), North Carolina (Research Triangle Park), and New York (Buffalo). In addition, our Chief Executive Officer works primarily from Auburn, Alabama. Our products and services are now delivered electronically – we no longer provide CD-ROMs and printed manuals or reports.



In our pharmaceutical software and services business, we compete against a number of established companies that provide screening, testing and research services, and products that are not based on simulation software. There are also software companies whose products do not compete directly with, but are sometimes closely related to, ours. Our competitors in this field include some companies with financial, personnel, research, and marketing resources that are larger than ours. Our management believes there is currently no significant competitive threat to GastroPlus; however, in spite of a high barrier to entry, one could be developed over time. Our new PKPlus software product will compete with one major and a few minor software programs; however, the capabilities and design features of PKPlus, along with more affordable licensing, are expected to generate significant interest. MedChem Studio, MedChem Designer, and ADMET Predictor/ADMET Modeler operate in a more competitive environment. Several other companies presently offer simulation or modeling software, or simulation-software-based services, to the pharmaceutical industry. We believe DILIsym and NAFLDsym enjoy a unique market position, with no significant competition.

Major pharmaceutical companies conduct drug discovery and development efforts through their internal development staffs and through outsourcing. Smaller companies generally need to outsource a greater percentage of this research. Thus, we compete not only with other software suppliers, but also with the in-house development teams at some of the larger pharmaceutical companies.

Although competitive products exist, both new licenses and license renewals for GastroPlus have continued to grow. We believe that we enjoy a dominant market share in this segment. We believe our ADMET Predictor/ADMET Modeler, MedChem Studio, MedChem Designer, DDDPlus, MembranePlus, PKPlus, KIWI, DILIsym, and NAFLDsym software offerings are each unique in their combination of capabilities and we intend to continue to market them aggressively.

We believe the key factors in our ability to successfully compete in this field are our ability to: (1) continue to invest in research and development, and develop and support industry-leading simulation and modeling software and related products and services to effectively predict activities and ADMET-related behaviors of new drug-like compounds, (2) design new molecules with acceptable activity and ADMET properties, (3) develop and maintain a proprietary database of results of physical experiments that serve as a basis for simulated studies and empirical models, (4) attract and retain a highly skilled scientific and engineering team, (5) aggressively our products and services to our global market, and (6) develop and maintain relationships with research and development departments of pharmaceutical companies, universities, and government agencies.

In addition, we actively seek strategic acquisitions to expand the pharmaceutical software and services business and to explore opportunities in aerospace and general healthcare.


Our business strategy is to do the things we need to do to promote growth both organically (i.e., by expanding our current products and services through in-house efforts) and by acquisition. We believe in the "Built to Last" approach - that the fundamental science and technologies that underlie our business units are the keys both to improving our existing products and to expanding the product line with new products that meet our various customers' needs. We believe the continued growth of our pharmaceutical software and services business segment is the result of steadily increasing adoption of simulation and modeling software tools across the pharmaceutical industry, as well as the world-class expertise we offer as consultants to assist companies involved in the research and development of new medicines. We have received a continuing series of study contracts with pharmaceutical companies ranging from several of the largest in the world to a number of medium-sized and smaller companies in the U.S. and Europe.

On July 23, 2014, we signed a merger agreement with Cognigen Corporation of Buffalo, New York. The merger closed on September 2, 2014, and Cognigen became our wholly owned subsidiary. We believe the combination of Simulations Plus and Cognigen provides substantial future potential based on the complementary strengths of each of the companies.

In June 2017, Simulation Plus acquired DILIsym Services, Inc. (DILIsym) as a wholly owned subsidiary pursuant to a stock purchase agreement dated May 1, 2017. On June 1, 2017, the Company consummated the acquisition of all outstanding equity interests of DILIsym pursuant to the terms of the Stock Agreement, with DILIsym becoming a wholly owned subsidiary of the Company. We believe the combination of Simulations Plus and DILIsym provides substantial future potential based on the complementary strengths of each of the companies. The acquisition of DILIsym positions the Company as the leading provider of Drug Induced Liver Injury (DILI) modeling and simulations software and contract research services . In addition to the DILIsym® software for analysis of potential drug-induced liver injury, DILIsym Services, Inc. also has developed a simulation program for analyzing nonalcoholic fatty liver disease (NAFLD) called NAFLDsym™.


It is our intent to continue to search for acquisition opportunities that are compatible with our current businesses and that are accretive, i.e., adding to both revenues and earnings.

In the fiscal year ended August 31, 2017 we distributed $0.20 per share in dividends to our shareholders. In November 2017, we distributed a quarterly dividend of $0.06 per share. We anticipate future dividends to be $0.06 per share per quarter; however, there can be no assurances that such dividends will be distributed, or if so, whether the amounts will be more, less, or the same as expected. The Board of Directors must approve each quarterly dividend distribution and may decide to increase, decrease, or eliminate dividend distributions at any time.

Net Revenues

Consolidated net revenues increased by 30.5% or $1.65 million to $7.07 million in the first fiscal quarter of Fiscal Year 2018 ("1QFY18") from $5.42 million in the first fiscal quarter of Fiscal Year 2017 ("1QFY17"). Changes by division are as follows:

· Lancaster: $346,000 increase, representing a 9.4% increase to $4.04 million
· Buffalo (Cognigen): $190,000 increase, representing an 11.1% increase to $1.91 million
· North Carolina (DILIsym): recorded revenues of $1.11 million. (Acquired June 1, 2017, they were not a part of the prior year numbers)

Consolidated software and software-related sales increased $342,000 or 10.0%, while consolidated consulting and analytical study revenues increased $1.31 million or 65.3% over 1QFY17.

Cost of Revenues

Consolidated cost of revenues increased by $400,000, or 29.9%, in 1QFY18 to $1.74 million from $1.34 million in 1QFY17. Labor-related cost accounted for $262,000 of this increase, a combination of increased labor count, salary increases, and bonuses at our subsidiaries based on increased earnings. Included in the increase was $139,000 of salary expense at DILIsym. Other significant increases in cost of revenues included $97,000 of direct contract expenses paid for testing at DILIsym, and approximately $119,000 of increased training related expenses as well as an additional $79,000 of amortization expense associated with acquired technologies associated with DILIsym's drug-induced liver injury technologies.

Cost of Revenues as a percentage of revenue remained fairly constant decreasing by 0.1% in 1QFY18 to 24.6% as compared to 24.7% in 1QFY17.

Gross Profit

Consolidated gross margin increased $1.25 million or 30.7%, to $5.33 million in 1QFY18 from $4.08 million in 1QFY17. $318,000 of this increase is from the California division, which showed an 82.4% gross margin. The Buffalo Division Gross margins increased $139,000 or 13.0% with margins of 63.1%, and DILIsym of North Carolina showed $794,000, a 71.2% margin.

Overall gross margin remained fairly constant increasing by 0.1% to 75.4% in 1QFY18 from 75.3.9% in 1QFY17.


Selling, General and Administrative Expenses

Selling, general, and administrative (SG&A) expenses increased $545,000, or 29.2% to $2.41 million in 1QFY18 from $1.86 million in 1QFY17. As a percent of revenues, SG&A was 34.1% for 1QFY18, compared to 29.2% in 1QFY17.

The major increases in SG&A expense were:

o Market expenses: $91,000 related to trade show and conference attendance
o Contract labor: $94,000 made up of outsources services and increased director compensation program costs
o G&A Salaries and Wages increased by $151,000; this increase is a combination of increased stock compensation costs of $47,000, salaries of $72,000 at DILIsym during the last fiscal quarter after acquisition, annual salary increases and increased head count in Lancaster and Buffalo
o Insurance Expense $66,000; mostly health-related medical costs due to cost increased and higher employee counts, of which $34,000 was associated with DILIsym
o Payroll tax expense increased $44,000, the effect of higher salary expense of which $22,000 was DILIsym
o Amortization expense increased $53,000 due to new acquisition amortization for DILIsym intangibles

The major decreases in SG&A expense were:

o Legal expenses decreased $52,000 due to a reduction in document review

Research and Development

Total research and development cost increased $343,000 in 1QFY18 compared to 1QFY17. In 1QFY18 we incurred approximately $868,000 of research and development costs, of this amount, $507,000 was capitalized and $361,000 was expensed. In 1QFY17 we incurred approximately $525,000 of research and development costs, of this amount, $235,000 was capitalized and $290,000 was expensed.

Other income (expense)

Other income was an expense of $47,000 compared to income of $39,000 in 1QFY17, a decrease of $86,000. Foreign currency exchange accounted for $47,000, the change mainly due to the yen strengthening in relation to the US dollar. An additional $38,000 of imputed interest expense associated with acquisition-related liabilities was the other major change.

Provision for Income Taxes

The provision for income taxes was $801,000 for 1QFY18 compared to $606,000 for 1QFY17. Our effective tax rate increased 1.0% to 31.8% in 1QFY18 from 30.8% in 1QFY17. The increase is a result of fewer tax deductions for stock based compensation in 1QFY18.

Net Income

Net income increased by $354,000, or 26.0%, in 1QFY18 to $1.72 million from $1.36 million in 1QFY17. Net earnings from our Lancaster division were up $33,000 or 3.1% to $1.11 million in 1QFY18. Net earnings for our Buffalo division were up $49,000 or 17.7% to $281,000 in 1QFY18. DILIsym (No. Carolina) net earnings were $272,000 for 1QFY17.

Liquidity and Capital Resources

Our principal sources of capital have been cash flows from our operations. We have achieved continuous positive operating cash flow over the last ten fiscal years. We believe that our existing capital and anticipated funds from operations will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for the foreseeable future. Thereafter, if cash generated from operations is insufficient to satisfy our capital requirements, we may open a revolving line of credit with a bank, or we may have to sell additional equity or debt securities or obtain expanded credit facilities. In the event such financing is needed in the future, there can be no assurance that such financing will be available to us, or, if available, that it will be in amounts and on terms acceptable to us. If cash flows from operations became insufficient to continue operations at the current level, and if no additional financing was obtained, then management would restructure the Company in a way to preserve its pharmaceutical business while maintaining expenses within operating cash flows.


Item 3. Quantitative and Qualitative Disclosures about Market Risk

As of November 30, 2017 and August 31, 2017, we had cash and cash equivalents of $7.05 million and $6.22 million, respectively. We do not hold any investments that are exposed to market risk related to changes in interest rates, which could adversely affect the value of our assets and liabilities, and we do not hold any instruments for trading purposes and investment. Some of our cash and cash equivalents are held in money market accounts; however, they are not exposed to market rate risk.

In the three months ended November 30, 2017 and 2016, we sold $580,000 and $554,000, respectively of software through representatives in certain Asian markets in local currencies. As a result, our financial position, results of operations, and cash flows can be affected by fluctuations in foreign currency exchange rates, particularly fluctuations in the yen and RMB exchange rates. These transactions give rise to receivables that are denominated in currencies other than the entity's functional currency. The value of these receivables are subject to changes because the receivables may become worth more or less due to changes in currency exchange rates. The majority of our software license agreements are denominated in U.S. dollars. We record foreign gains and losses as they are realized. We mitigate our risk from foreign currency fluctuations by adjusting prices in our foreign markets on a periodic basis. We base these changes on market conditions while working closely with our representatives. We do not hedge currencies or enter into derivative contracts.

Item 4. Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of November 30, 2017. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, management concluded as of November 30, 2017, that our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

No change in the Company's internal controls over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) occurred during the Company's most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.



Item 1. Legal Proceedings

We are not a party to any legal proceedings and are not aware of any pending legal proceedings of any kind. 

Item 1A. Risk Factors

Please carefully consider the information set forth in this Quarterly Report on Form 10-Q and the risk factors discussed in Part I, "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended August 31, 2017, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K, as well as other risks and uncertainties, could materially and adversely affect our business, results of operations and financial condition, which in turn could materially and adversely affect the trading price of shares of our Common Stock. Additional risks not currently known or currently material to us may also harm our business.
