Overview

ZIOPHARM Oncology, Inc., which is referred to herein as “Ziopharm,” the “Company,” or “we”, is a biopharmaceutical company seeking to develop, acquire, and commercialize, on its own or with partners, a diverse portfolio of immuno-oncology therapies.

The Company’s operations to date have consisted primarily of raising capital and conducting research and development. The Company’s fiscal year ends on December 31.

The Company has operated at a loss since its inception in 2003 and has minimal revenues. The Company anticipates that losses will continue for the foreseeable future. At September 30, 2018, the Company’s accumulated deficit was approximately $761.2 million. Given its current development plans, the Company anticipates cash resources will be sufficient to fund operations into the second quarter of 2019. The Company’s ability to continue operations after its current cash resources are exhausted depends on its ability to obtain additional financing in the near term or to achieve profitable operations, as to which no assurances can be given. Cash requirements may vary materially from those currently planned because of changes in the Company’s focus and direction of its research and development programs, competitive and technical advances, patent developments, regulatory changes or other developments. Additional financing will be required to continue operations after the Company exhausts its current cash resources and to continue its long-term plans for clinical trials and new product development.

As of September 30, 2018, the Company had approximately $31.7 million of cash and cash equivalents. Given its development plans, the Company anticipates cash resources will be sufficient to fund its operations into the second quarter of 2019 and the Company has no committed sources of additional capital. Based on the forecast, management determined that there is substantial doubt regarding our ability to continue as a going concern. The forecast of cash resources is forward-looking information that involves risks and uncertainties, and the actual amount of the Company’s expenses could vary materially and adversely as a result of a number of factors. The Company has based its estimates on assumptions that may prove to be wrong, and the Company’s expenses could prove to be significantly higher than currently anticipated. Management does not know whether additional financing will be available on terms favorable or acceptable to the Company when needed, if at all. If adequate additional funds are not available when required, or if the Company is unsuccessful in entering into partnership agreements for further development of its products, management may need to curtail development efforts.

Basis of Presentation

The accompanying unaudited interim financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. Certain information and note disclosures required by generally accepted accounting principles in the United States have been condensed or omitted pursuant to such rules and regulations.

It is management’s opinion that the accompanying unaudited interim financial statements reflect all adjustments (which are normal and recurring) that are necessary for a fair statement of the results for the interim periods. The unaudited interim financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2017, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed with the SEC on March 1, 2018, as amended, or the Form 10-K.

The results disclosed in the statements of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the full fiscal year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although the Company regularly assesses these estimates, actual results could differ from those estimates. Changes in estimates are recorded in the period in which they become known.

The Company’s most significant estimates and judgments used in the preparation of its financial statements are:

•

Clinical trial expenses;

•

Collaboration agreements and revenue recognition;

•

Fair value measurements of stock based compensation and Series 1 preferred stock; and

•

Income taxes
