NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2017

The information presented herein as of June 30, 2017 and for the three and six months ended June 30, 2017 and 2016 is unaudited.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

The following is a summary of the more significant accounting policies of CTD Holdings, Inc. and subsidiaries (“we” “our”, “us” or the “Company”) that affect the accompanying consolidated financial statements.

(a) ORGANIZATION AND OPERATIONS––The Company was incorporated in August 1990, as a Florida corporation with operations beginning in July 1992. We are a biotechnology company that develops cyclodextrin-based products for the treatment of disease. We have filed a Type II Drug Master File with the U.S. Food and Drug Administration (“FDA”) for our lead drug candidate, Trappsol® Cyclo™ as a treatment for Niemann-Pick Type C disease (“NPC”), a rare and fatal cholesterol metabolism disease that impacts the brain, lung, liver, spleen, and other organs. The FDA recently approved our Investigational New Drug application (IND) which describes our Phase I clinical plans in the U.S. for Trappsol® Cyclo™ and in January 2017 the FDA granted Fast Track designation to Trappsol® Cyclo™ for the treatment of NPC. Initial patient enrollment in the U.S. Phase I study is expected to occur in September 2017. We have also filed Clinical Trial Applications with several European regulatory bodies, including those in the United Kingdom, Sweden and Italy, all of which have approved our applications. The first patient was dosed in our European study in July 2017.

We also sell cyclodextrins and related products to the pharmaceutical, nutritional, and other industries, primarily for use in diagnostics and specialty drugs with continuing growth in research and new product development. However, our core business has transitioned to a biotechnology company primarily focused on the development of cyclodextrin-based biopharmaceuticals for the treatment of disease from a business which had been primarily reselling basic cyclodextrin products. 

(b) BASIS OF PRESENTATION––The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

Operating results for the three and six month periods ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016, as filed with the Securities and Exchange Commission on March 17, 2017.

(c) CASH AND CASH EQUIVALENTS––Cash and cash equivalents consist of cash and any highly liquid investments with an original maturity of three months or less.

(d) ACCOUNTS RECEIVABLE––Accounts receivable are unsecured and non-interest bearing and stated at the amount we expect to collect from outstanding balances. Based on our assessment of the credit history with customers having outstanding balances and current relationships with them, we have concluded that losses on balances outstanding at June 30, 2017 and December 31, 2016 will be immaterial.

(e) INVENTORY AND COST OF PRODUCTS SOLD––Inventory consists of our pharmaceutical drug Trappsol® Cyclo™, cyclodextrin products and chemical complexes purchased for resale recorded at the lower of cost (first-in, first-out) or market. Cost of products sold includes the acquisition cost of the products sold and does not include any allocation of inbound or outbound freight charges, indirect overhead expenses, warehouse and distribution expenses, or depreciation expense.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2017

(f) FURNITURE AND EQUIPMENT––Furniture and equipment are recorded at cost. Depreciation on furniture and equipment is computed using primarily the straight-line method over the estimated useful lives of the assets (generally three to five years for computers and vehicles, and seven to ten years for machinery and furniture).

(g) REVENUE RECOGNITION––We recognize revenue from product sales, and royalties when the following four revenue recognition criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the selling price is fixed or determinable, and collectability is reasonably assured. Product sales and shipping revenues, net of any discounts or return allowances, are recorded when the products are shipped and title passes to customers. Sales to customers are made pursuant to a sales contract that provides for transfer of both title and risk of loss upon our delivery to the carrier. Return allowances, which reduce product revenue, have been historically infrequent, and are recorded when they become known. Amounts received in advance are deferred and recognized as revenue when all four revenue recognition criteria have been met. There is no deferred revenue at June 30, 2017 and December 31, 2016.

(h) RESEARCH AND DEVELOPMENT COSTS––Research and development costs are expensed as incurred.

(i) INCOME TAXES––Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. In addition, tax benefits related to positions considered uncertain are recognized only when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions shall initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts.

(j) NET LOSS PER COMMON SHARE––Basic and fully diluted net loss per common share is computed using a simple weighted average of common shares outstanding during the periods presented; outstanding warrants to purchase 15,085,787 and 9,057,500 common shares were antidilutive for the three and six months ended June 30, 2017 and 2016, respectively, and have been excluded from the calculation of loss per common share.

(k) STOCK BASED COMPENSATION––The Company periodically awards stock to employees, directors, and consultants. An expense is recognized equal to the fair value of the stock determined using the closing trading price of the stock on the award date.

(l) CONCENTRATIONS OF CREDIT RISK––Significant concentrations of credit risk for all financial instruments owned by the Company are as follows:

(i) DEMAND AND CERTIFICATE OF DEPOSITS––We maintain bank accounts in Federal credit unions and other financial institutions, which are insured up to the Federal Deposit Insurance Corporation limits. The bank accounts may exceed Federally insured levels; however, we have not experienced any losses in such accounts.

(ii) ACCOUNTS RECEIVABLE––Our accounts receivable consist of amounts due primarily from chemical supply and pharmaceutical companies located primarily in the United States. Two customers accounted for 87% of the accounts receivable balance at June 30, 2017. Two customers accounted for 81% of the accounts receivable balance at December 31, 2016. We have no policy requiring collateral or other security to support our accounts receivable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2017

(m) LIQUIDITY––For the year ended December 31, 2016, the Company incurred a net loss of $4,223,841 and used $2,950,938 of cash flows in its operations. At December 31, 2016, the Company had a cash balance of $960,197 and its current assets less current liabilities were $1,292,991. For the six months ended June 30, 2017, the Company incurred a net loss of $1,815,244 and used net cash in operations in the amount of $1,498,080. At June 30, 2017, the Company had a cash balance of $1,330,587 and its current assets less current liabilities were $1,416,516. On February 23, 2017, the Company generated additional net proceeds of $1,851,055 from the sale of equity securities in a private placement. The Company has concluded that proceeds from the private placement of its securities are currently the primary source of its cash flows that will permit the Company to meet its financial obligations as they come due through August 2018 despite its history of net losses. The Company continues to actively seek additional capital through the sale of its common stock. In the event that the Company cannot raise sufficient capital, management may be required to reduce expenditures related to its operations. Further, if the Company is unable to raise sufficient capital in the near-term, the inability to do so could have a significant adverse effect on its future financial condition, results of operations, and cash flows.

(n) USE OF ESTIMATES––The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although management bases its estimates on historical experience and assumptions that are believed to be reasonable under the circumstances, actual results could significantly differ from these estimates.

(o) RECLASSIFICATIONS – Certain amounts in the 2016 financial statements have been reclassified to conform to the 2017 presentation. These reclassifications had no effect on previously reported net income or stockholders equity.

(2) MORTGAGE NOTE RECEIVABLE

On January 21, 2016, we sold our real property located in High Springs, Florida to an unrelated party. This property was previously classified on our balance sheet as property held for sale, with a carrying value of $275,000. Pursuant to the terms of the sale, at the closing, the buyer paid $10,000 in cash, less selling costs and settlement charges, and delivered to us a promissory note in the principal amount of $265,000, and a mortgage in our favor securing the buyer’s obligations under the promissory note. The promissory note provides for monthly payments of $3,653, including principal and interest at 4.25%, over a seven-year period that commenced March 1, 2016, with the unpaid balance due in February 2023.

 (3) EQUITY TRANSACTIONS:

The Company expensed $63,640 and $85,140 in employee and board member stock compensation for the three and six months ended June 30, 2017, respectively. The Company expensed $35,560 and $70,760 in employee and board member stock compensation for the three and six months ended June 30, 2016, respectively. The Company accrues stock compensation expense over the period earned for employees and board members. On March 31, 2017, the Company issued 172,000 shares of common stock valued at $67,100 to eight board members and the Company’s secretary as settlement of accrued stock compensation for prior service. In July 2017, 120,000 shares were issued to employees as bonus compensation.

On February 23, 2017, the Company issued 5,754,832 units (“Units”) at a purchase price of $0.35 per Unit in a private placement, each Unit consisting of one share of its common stock, and a seven-year warrant to purchase an additional share of common stock at an exercise price of $0.35, for aggregate gross proceeds to the Company of $2 million. Scarsdale Equities LLC acted as financial advisor to the Company in connection with the private placement and was paid a cash fee of approximately $153,000, and it and its designees were issued seven-year warrants to purchase 273,455 Units at an exercise price of $0.35 per Unit.

CTD HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2017

As of June 30, 2017, the Company had warrants outstanding to purchase 14,332,332 shares of common stock at exercise prices of $0.25 - $1.00 per share that expire in various years until 2024. In addition, there are seven-year warrants outstanding at June 30, 2017 to purchase 753,455 Units at exercise prices of $0.25-$0.35 per Unit.

(4) INCOME TAXES:

The Company reported a net loss for the three and six months ended June 30, 2017 and 2016, respectively. The Company increased its deferred tax asset valuation allowance rather than recognize an income tax benefit.

(5) SALES CONCENTRATIONS:

Sales to two major customers accounted for 66% of total sales for the six months ended June 30, 2017. Sales to two major customers accounted for 64% of total sales for the six months ended June 30, 2016. A loss of one of these customers could have a significant adverse effect on the Company’s financial condition, results of operations and cash flows.

Overview

CTD Holdings, Inc. (“we” “our” “us” or “the Company”) was organized as a Florida corporation on August 9, 1990, with operations beginning in July 1992. In conjunction with a restructuring in 2000, we changed our name from Cyclodextrin Technologies Development, Inc., or CTDI, to CTD Holdings, Inc.; CTDI was then incorporated as a Florida corporation and became a wholly owned subsidiary of CTD Holdings, Inc.

We have also filed Clinical Trial Applications for a Phase I/II clinical study with several European regulatory bodies, including those in the United Kingdom, Sweden and Italy, all of which have approved our applications. The European Phase I/II study will evaluate the safety of Trappsol® Cyclo™ along with a range of clinical outcomes, including neurologic, hepatic, and respiratory, in addition to measurements of cholesterol metabolism and markers of NPC. The European study is similar to the U.S. study, providing for the administration of Trappsol® Cyclo™ intravenously to NPC patients every two weeks in a double-blind, randomized trial. The first patient was dosed in this study in July 2017.

Substantially all of our revenues are derived from the sale of cyclodextrins, including bio-pharmaceuticals containing cyclodextrins, cyclodextrin complexes, resale of cyclodextrins manufactured by others for our clients to their specifications, and our own licensed cyclodextrin products.  We have trademarked certain products under our Trappsol®, Aquaplex®, and AP™-Flavor product lines.  We currently sell our products directly to customers in the diagnostics, pharmaceutical, and industrial chemical industries, and to chemical supply distributors.  

Trappsol® Cyclo™

At the end of 2008, we provided Trappsol® Cyclo™ to a customer for compassionate use as an Investigational New Drug to treat a set of twins in the U.S. who were diagnosed with NPC, also known as Childhood Alzheimer’s. NPC is a fatal disease caused by a genetic defect that prevents proper handling of cholesterol in the body’s cells. The patient’s treatment with our Trappsol® Cyclo™ product proved to provide an ameliorative benefit. On May 17, 2010, the FDA granted orphan drug status to our customer for Trappsol® Cyclo™ for the treatment of NPC. To date, Trappsol® Cyclo™ has been administered to approximately 20 NPC patients in compassionate use programs around the world, including in the U.S., Brazil, Spain and Norway. Our annual sales of Trappsol® Cyclo™ increased to $697,000 for 2016 from $352,000 for 2015. Sales of Trappsol® Cyclo™ were $314,000 and $386,000 for the six months ended June 30, 2017 and 2016, respectively. In 2012, we began to offer 100ml vials of Trappsol® Cyclo™ in a liquid form from a contract manufacturer. In 2014, we completed validation of the Trappsol® Cyclo™ manufacturing process and submitted a Type II Drug Master File to the FDA. In 2015 we established an International Clinical Program that includes a team of experienced drug development companies and individuals. We have also obtained Orphan Drug Designation for Trappsol® Cyclo™ in both the U.S. and Europe.

Resale of Cyclodextrin and Cyclodextrin Complexes

Our sales of cyclodextrins and cyclodextrin complexes are primarily to chemical supply houses around the world, to pharmaceutical companies, to food companies for research and development and to diagnostics companies.

We acquire our products principally from outside the United States, including from Wacker Biosolutions, a division of Wacker Chemie AG (Germany), with a production facility located in Adrian, Michigan and Hangzhou Pharma and Chem Co. (China), Quian Hui (China), and Cyclodextrin Research & Development Laboratory (Hungary), but are gradually finding satisfactory supply sources in the United States. While we enjoy lower supply prices from outside the United States, changes in shipping costs and currency exchange rates are making domestic sources more competitively priced. We make patent information about cyclodextrins available to our customers. We also offer our customers our knowledge of the properties and potential new uses of cyclodextrins and complexes.

As most of our customers use our cyclodextrin products in their research and development activities, the timing, product mix, and volume of their orders from us are unpredictable. We also have four large customers (each of whom has historically purchased from us annually and, depending upon the year, may account for greater than 10% of our annual revenues) who have a significant effect on our revenues when they increase or decrease their research and development activities that use cyclodextrins. We keep in constant contact with these customers as to their cyclodextrin needs so we can maintain the proper inventory composition and quantity in anticipation of their needs. The sales to large customers and the product mix and volume of products sold has a significant effect on our revenues and product margins. These factors contribute to our revenue volatility from quarter to quarter and year to year.

 Liquidity and Capital Resources

Our cash increased to $1,331,000 as of June 30, 2017, compared to $960,000 as of December 31, 2016. Our current assets less current liabilities were $1,417,000 as of June 30, 2017, compared to $1,293,000 at December 31, 2016. We used $1,498,000 in operations for the six months ended June 30, 2017, compared to $1,530,000 for the same period in 2016. We repaid all of our bank debt in December 2016 with proceeds from the sales of our real property and manufacturing facility.

On February 23, 2017, we generated additional net proceeds of $1,851,000 from the sale of our equity securities in a private placement.

We plan to use our available cash primarily for the development of our Trappsol® Cyclo™ orphan drug product, including implementation of our International Clinical Program and U.S. clinical trials and designs, and other general corporate purposes.

We presently believe the Company has sufficient cash to meet its anticipated operating costs and capital expenditure requirements for at least the next twelve months. We expect to continue to raise additional capital through the sale of our securities from time to time for the foreseeable future to fund the development of our drug product candidates through clinical development, manufacturing and commercialization. Our ability to obtain such additional capital will likely be subject to various factors, including our overall business performance and market conditions.

We have no off-balance sheet arrangements at June 30, 2017.

Results of Operations - Three and Six Months Ended June 30, 2017 Compared to Three and Six Months Ended June 30, 2016

We reported a net loss of $(828,000) and $(1,815,000) for the three and six months ended June 30, 2017, respectively, compared to a net loss of $(1,071,000) and $(1,777,000) for the three and six months ended June 30, 2016, respectively.  

Total revenues for the three month period ended June 30, 2017 increased 36% to $523,000 compared to $384,000 for the same period in 2016. Total revenues for the six month period ended June 30, 2017 increased 19% to $828,000 compared to $697,000 for the same period in 2016.

Our change in the mix of our product sales for the three and six months ended June 30, 2017 and 2016 is as follows:

Trappsol® Cyclo

Our sales of Trappsol® Cyclo™ increased by 19% for the three month period ended June 30, 2017, to $287,000 from $241,000 for the three month period ended June 30, 2016.  Our sales of Trappsol® Cyclo™ decreased by 19% for the six month period ended June 30, 2017, to $314,000 from $386,000 for the six month period ended June 30, 2016. Our sales to a particular customer who exports Trappsol® Cyclo™ to South America were $287,000 (100% of total sales of Trappsol® Cyclo™) for the three months ended June 30, 2017, compared to $231,000 (96% of total sales of Trappsol® Cyclo™) for the three months ended June 30, 2016; and our sales to that same customer who exports Trappsol® Cyclo™ to South America were $287,000 (91% of total sales of Trappsol® Cyclo™) for the six month period ended June 30, 2017, compared to $365,000 (95% of total sales of Trappsol® Cyclo™) for the six month period ended June 30, 2016. Our annual 2016 sales to this customer were $669,000 (96% of total 2016 sales of Trappsol® Cyclo™).  This product is designated as an orphan drug; the population of patients is small and while we expect our future sales to increase, the timing of sales will be unpredictable and our ability to market the drug for use other than research is severely constrained by regulatory restrictions in the applicable jurisdictions.  

Trappsol® HPB

Our sales of Trappsol® HPB increased by 102% for the three month period ended June 30, 2017, to $182,000 from $90,000 for the three months ended June 30, 2016. Our sales of Trappsol® HPB increased by 85% for the six month period ended June 30, 2017, to $422,000 from $228,000 for the six month period ended June 30, 2016.

Trappsol® other products

Our sales of other Trappsol® products increased by 104% for the three month period ended June 30, 2017, to $51,000 from $25,000 for the three month period ended June 30, 2016. Our sales of other Trappsol® products increased by 75% for the six month period ended June 30, 2017, to $70,000 from $40,000 for the six month period ended June 30, 2016.

Aquaplex®

There were negligible sales of Aquaplex® for the three month period ended June 30, 2017 compared to $21,000 for the three month period ended June 30, 2016. Our sales of Aquaplex® were $17,000 for the six month period ended June 30, 2017 compared to $21,000 for the six month period ended June 30, 2016.

Our largest customers continue to follow historical product ordering trends by placing periodic large orders that represent a significant share of our annual sales volume. During the six months ended June 30, 2017, our two largest customers accounted for 66% of our sales; the largest accounted for 34% of sales. During the six months ended June 30, 2016, our three largest customers accounted for 73% of our sales; the largest accounted for 54% of sales. Historically, our usual smaller sales of HPB occur more frequently throughout the year compared to our large sales that we receive periodically. The timing of when we receive and are able to complete these two kinds of sales has a significant effect on our quarterly revenues and operating results and makes period to period comparisons difficult.

Our cost of products sold (excluding any allocation of direct and indirect overhead and handling costs) as a percentage of sales for the six month period ended June 30, 2017 was 12% ($98,000) compared to 13% ($93,000) for the same period in 2016. Our cost of products sold (excluding any allocation of direct and indirect overhead and handling costs) as a percentage of sales was 15% ($79,000) for the three months ended June 30, 2017 compared to 15% ($56,000) for the same period in 2016.  Historically, the timing and product mix of sales to our large customers has had a significant effect on our sales, cost of products sold (excluding any allocation of direct and indirect overhead and handling costs) and the related margin. We did not experience any significant increases in material costs during 2016 or 2015, or the first six months of 2017.

Our gross margins may not be comparable to those of other entities, since some entities include all the costs related to their distribution network in cost of goods sold. Our cost of goods sold includes only the cost of products sold and does not include any allocation of inbound or outbound freight charges, indirect overhead expenses, warehouse and distribution expenses, or depreciation expense. We have six employees who provide receiving, inspection, warehousing and shipping operations for us. The cost of these employees, and our other employees, are included in personnel expense. Our other costs of warehousing and shipping functions are included in office and other expense.

As we buy most of our inventory from foreign suppliers, the change in the value of the U.S. dollar in relation to the Euro, Yen and Yuan has had and will continue to have an effect on our cost of inventory. Our main supplier of specialty cyclodextrins and complexes, Cyclodextrin Research & Development Laboratory, is located in Hungary and its prices are set in Euros.

Personnel expenses decreased to $305,000 for the three months ended June 30, 2017 from $381,000 for the three months ended June 30, 2016. Personnel expenses decreased to $639,000 for the six months ended June 30, 2017 from $682,000 for the six months ended June 30, 2016. The decrease in personnel expense is due to the sale of our office and manufacturing facility in December 2016.

Research and development expenses decreased to $527,000 for the three months ended June 30, 2017, from $661,000 for the three months ended June 30, 2016. Research and development expenses increased to $1,171,000 for the six months ended June 30, 2017, from $944,000 for the six months ended June 30, 2016. Research and development expenses as a percentage of our total operating expenses increased to 44% for the six months ended June 30, 2017 from 39% for the six months ended June 30, 2016. The increase in research and development expense is due to the International Clinical Program. We expect future research and development costs to increase as we continue to seek regulatory approval for the use of Trappsol® Cyclo™ in the treatment of NPC.

Repairs and maintenance expenses decreased to $1,000 for the three months ended June 30, 2017 from $10,000 for the three months ended June 30, 2016. Repairs and maintenance expenses decreased to $4,000 for the six months ended June 30, 2017 from $16,000 for the six months ended June 30, 2016.

Professional fees increased to $302,000 for the three months ended June 30, 2017, compared to $77,000 for the three months ended June 30, 2016.
