CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q, or Quarterly Report, contains forward-looking statements within the meaning of the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts contained in this Quarterly Report are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “design,” “aim,” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. All statements other than statements of historical fact contained in this Quarterly Report, including without limitation statements regarding our future results of operations and financial position; the anticipated impact of the COVID-19 pandemic on our business, global supply chain issues and increased inflation and interest rates; the sufficiency of our cash and cash equivalents to fund our operations; business strategy; potentially differentiated product profiles; the potential benefits of our product candidates; potential market opportunity for our product candidates; dose optimization activities and the timing thereof; timing of expected milestones and the announcement thereof; prospective products and product candidates; clinical trial timelines and expected timing for the release of data; research and development costs, future revenue; timing and likelihood of success, activities under our existing collaborations and potential collaboration opportunities; and plans and objectives of management are forward-looking statements.

The forward-looking statements in this Quarterly Report are only predictions and are based largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this Quarterly Report and are subject to a number of known and unknown risks, uncertainties, assumptions and other important factors, including those described under “Summary Risk Factors” below and in the sections in this Quarterly Report entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Quarterly Report.
Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, they may turn out to be inaccurate and you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results, financial condition, performance or achievements could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we assume no obligation to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

SUMMARY RISK FACTORS

Our business is subject to numerous risks and uncertainties, including those described in Part II, Item 1A. “Risk Factors” in this Quarterly Report on Form 10-Q. You should carefully consider these risks and uncertainties when investing in our common stock. The principal risks and uncertainties affecting our business include the following:

We have a limited operating history and have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability.
We have incurred significant net losses since inception and we expect to continue to incur significant net losses for the foreseeable future.
We will require substantial additional capital to finance our operations. If we are unable to raise such capital when needed, or on acceptable terms, we may be forced to delay, reduce or eliminate one or more of our research and drug development programs or future commercialization efforts.
We are substantially dependent on the success of our lead product candidates, ZN-c3 and/or ZN-d5, which are currently in clinical trials. If we are unable to complete development of, obtain approval for and commercialize ZN-c3 and/or ZN-d5 in a timely manner, our business will be harmed.
The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA, EMA or other comparable foreign regulatory authorities.
We intend to develop ZN-c3 and ZN-d5 and potentially other product candidates in combination with other therapies, which exposes us to additional risks.
The regulatory approval processes of the U.S. Food and Drug Administration, or FDA, and other comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable. If we are ultimately unable to obtain regulatory approval for our product candidates, we will be unable to generate product revenue and our business will be substantially harmed.

We face significant competition and, if our competitors develop and market technologies or products more rapidly than we do or that are more effective, safer or less expensive than the product candidates we develop, our commercial opportunities will be negatively impacted.
Our success depends on our ability to protect our intellectual property and our proprietary platform. If we are unable to adequately protect our intellectual property and our proprietary platform, or to obtain and maintain issued patents that are sufficient to protect our product candidates, then others could compete against us more directly, which would negatively impact our business.
Our existing collaborations are important to our business and future collaborations may also be important to us and, if we are unable to maintain any of these collaborations, or if these arrangements are not successful, our business could be adversely affected.
We rely, and expect to continue to rely, on third parties, including independent clinical investigators and CROs, to conduct certain aspects of our preclinical studies and clinical trials. If these third parties do not successfully carry out their contractual duties, comply with applicable regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.
Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and commercialization efforts.
The competition for qualified personnel is particularly intense in our industry. If we are unable to retain or hire key personnel, then we may not be able to sustain or grow our business.
The COVID-19 pandemic has adversely impacted, and we expect will continue to adversely impact, our business, including our preclinical studies and clinical trials.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Business
Organization
Zentalis Pharmaceuticals, Inc. (“Zentalis”, “We” or the “Company”) is a clinical-stage pharmaceutical company focused on discovering and developing clinically differentiated, novel small molecule therapeutics targeting fundamental biological pathways of cancer. The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. All of the Company’s tangible assets are held in the United States.
Liquidity
Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year from the financial statement issuance date. The Company determined that there are no conditions or events that raise substantial doubt about its ability to continue as a going concern within one year after the date that the interim unaudited condensed consolidated financial statements for the quarter ended September 30, 2022 are issued.
2. Interim Unaudited Financial Statements
Basis of Presentation
The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) related to a quarterly report on Form 10-Q. The year-end condensed consolidated balance sheet data was derived from the Company’s audited financial statements but do not include all disclosures required by U.S. GAAP. These interim unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 24, 2022. The unaudited financial information for the interim periods presented herein reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial condition and results of operation for the periods presented, with such adjustments consisting only of normal recurring adjustments. Certain reclassifications have been made to the prior period condensed consolidated balance sheet to conform to the current period presentation.
The accompanying interim unaudited condensed consolidated financial statements include our wholly-owned subsidiaries and variable interest entities (“VIEs”) for the periods in which we determined we were the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.
We evaluate our ownership, contractual and other interests in entities that are not wholly-owned to determine if these entities are VIEs, and, if so, whether we are the primary beneficiary of the VIE. In determining whether we are the primary beneficiary of a VIE and therefore required to consolidate the VIE, we apply a qualitative approach that determines whether we have both (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of, or the rights to receive benefits from, the VIE that could potentially be significant to that VIE.
We will continuously assess whether we are the primary beneficiary of a VIE, as changes to existing relationships or future transactions may result in the consolidation or deconsolidation of such VIE. During the
11


periods presented, we have not provided any other material financial or other support to our VIEs that we were not contractually required to provide.
The equity method is used to account for investments in which we have the ability to exercise significant influence, but not control, over the investee. Such investments are recorded on the balance sheet, and the share of net income or losses of equity investments is recognized on a one quarter lag in investment and other income (expense), net.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates and judgments, which are based on historical and anticipated results and trends and on various other assumptions that management believes to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ from management’s estimates.
Though the impact of the COVID-19 pandemic to our business and operating results presents additional uncertainty, we continue to use the best information available to inform our critical accounting estimates.
Significant Accounting Policies
During the nine months ended September 30, 2022, there have been no changes to the Company’s significant accounting policies as described in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021.
3. Significant Transactions
Zentera Therapeutics
In May 2020, we became a majority common shareholder of Zentera Therapeutics, Ltd., a Shanghai-based clinical-stage biopharmaceutical company focused on developing cancer therapeutics (“Zentera”), concurrent with its Series A convertible preferred stock offering. The financial position and results of operations of Zentera were included in our consolidated financial statements from the date of the initial investment as a result of our control of the entity and our determination that we were the primary beneficiary of Zentera. In July 2021, Zentera completed a Series B convertible preferred stock offering which diluted our investment to a position of less than majority owned. Upon review of the facts and circumstances, together with the authoritative accounting literature, we determined that while Zentera is a VIE, consolidation of Zentera is no longer appropriate. After the July 2021 Series B convertible preferred offering in which we did not participate, our review concluded that we ceased to be the primary beneficiary of Zentera as our equity ownership was reduced and changes were made to the corporate governance of Zentera. As a result, we no longer individually have the ability to direct the activities that most significantly impact Zentera's economic performance.
Beginning in July 2021, the financial position and results of operations of Zentera were no longer included in our consolidated financial statements. During the period of deconsolidation we measured the fair value of our retained investment in Zentera using the backsolve method with consideration for a lack of marketability. An equity method investment of $28.0 million is recorded on our balance sheet at September 30, 2022. This amount represents our maximum exposure to loss as a result of our involvement with Zentera. A deferred tax liability of $5.9 million representing the tax impact of the unrealized gain on deconsolidation is recorded on our balance sheet at September 30, 2022. A gain of $51.6 million, measured as the difference between the fair value of our retained noncontrolling interest together with the carrying amount of the Zentera noncontrolling interest, and the carrying amount of Zentera’s assets and liabilities was recognized during the year ended December 31, 2021. The difference between the carrying amount of our investment in Zentera and our portion of the Zentera net assets was $5.0 million
12


as of September 30, 2022. This difference is accounted for in our equity method investment analogous to in-process research and development.
In May 2020, each of our subsidiaries Zeno Alpha, Inc., K-Group Alpha, Inc., Zeno Management Inc., and K-Group Beta, Inc. entered into a collaboration and royalty-bearing license agreement with Zentera, which we refer to as the “Zentera Sublicenses,” pursuant to which we collaborate with Zentera on the development and commercialization of ZN-c3 and ZN-d5, collectively referred to as the “Collaboration Products,” respectively, in the People’s Republic of China, Macau, Hong Kong and Taiwan, which is referred to as the “Zentera Collaboration Territory.” Under each Zentera Sublicense, Zentera will lead development, and upon regulatory approval, the commercialization, of the collaboration products in the Zentera Collaboration Territory.
Under the terms of the Zentera Sublicenses, Zentera is responsible for the costs of developing the Collaboration Products in the Zentera Collaboration Territory, and we are responsible for the costs of developing the Collaboration Products outside the Zentera Collaboration Territory, provided that Zentera will reimburse us for a portion of the costs for global data management, pharmacovigilance, safety database management, and chemistry, manufacturing and controls activities with respect to each Collaboration Product. Prior to the deconsolidation of Zentera in July 2021, these costs were eliminated in consolidation. For the three and nine months ended September 30, 2022, the amounts incurred under this arrangement totaled $3.2 million and $8.3 million, respectively, and are presented as contra-research and development expense in the unaudited condensed consolidated statement of operations. A corresponding receivable is recorded within prepaid expenses and other current assets on the unaudited condensed consolidated balance sheet. We have not provided material financial or other support to Zentera during the periods ended September 30, 2022 and 2021 that was not previously contractually required.

4. Business Combinations
Kalyra Pharmaceuticals, Inc.
On December 21, 2017, we acquired $4.5 million of Kalyra Pharmaceuticals, Inc.’s (“Kalyra”) Series B Preferred Stock representing a 25% equity interest in Kalyra for purposes of entering the analgesics therapeutic research space. The acquisition price was paid entirely in cash.
In accordance with the authoritative guidance, we concluded that Kalyra is a business consisting of inputs, employees, intellectual property and processes capable of producing outputs. Additionally, we have concluded that Kalyra is a VIE, we are the primary beneficiary and have the power to direct the activities that most significantly affect Kalyra’s economic performance through common management and our board representation. Prior to December 21, 2017, the Company and Kalyra transacted for the delivery of research and development services and support. The financial position and results of operations of Kalyra have been included in our consolidated financial statements from the date of the initial investment.
Pursuant with authoritative guidance, we have recorded the identifiable assets, liabilities and noncontrolling interests in the VIE at their fair value upon initial consolidation. The identified goodwill is comprised of the workforce and expected synergies from combining the entities. Total assets and liabilities of Kalyra as of September 30, 2022 and December 31, 2021 are immaterial. The liabilities recognized as a result of consolidating Kalyra do not represent additional claims on our general assets. Pursuant to the authoritative guidance, the equity
13


interest in Kalyra not owned by Zentalis is reported as a noncontrolling interest on our condensed consolidated balance sheets.
The following is a reconciliation of equity (net assets) attributable to the noncontrolling interest (in thousands):

As of September 30, 2022, sixty-five of our available-for-sale debt securities with a fair market value of $369.4 million were in a gross unrealized loss position of $2.3 million. When evaluating an investment for impairment, we review factors such as the severity of the impairment, changes in underlying credit ratings, forecasted recovery, our intent to sell or the likelihood that we would be required to sell the investment before its anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. Based on our review of these marketable securities, we believe none of the unrealized loss is as a result of a credit loss as of September 30,
14


2022, because we do not intend to sell these securities, and it is not more-likely-than-not that we will be required to sell these securities before the recovery of their amortized cost basis.

9. Stockholders’ Equity
Direct Offering of Common Stock
On April 29, 2022, pursuant to our Registration Statement on Form S-3 (Registration No. 333-255769), filed with the SEC on May 4, 2021, we completed a direct offering of common stock to Pfizer Inc. (“Pfizer”). We issued and sold 953,834 shares of our common stock at an offering price of $26.21 per share. The total gross proceeds for the offering were approximately $25.0 million, before deducting offering expenses of $0.3 million payable by us. The parties have entered into an agreement to collaborate to advance the clinical development of ZN-c3, a selective Wee1 inhibitor designed to induce synthetic lethality in cancer cells. We did not grant Pfizer any economic ownership or control of ZN-c3 or the rest of our pipeline. $4.2 million of the gross offering proceeds received from Pfizer represented a premium in excess of the fair value of our common stock on the date of the investment. This amount has been recorded as accrued research and development expense on the unaudited condensed consolidated balance sheet and will be recognized as a reduction of research and development expense over the term of the collaboration agreement.
Follow-on Offering of Common Stock
On May 18, 2022, we completed a follow-on offering in which we issued and sold 10,330,000 shares of common stock at a public offering price of $19.38 per share. The total gross proceeds for the offering were approximately $200.2 million, before deducting offering expenses of $11.4 million payable by us.
Share-based Compensation

In April 2020, the Company’s Board of Directors adopted, and the Company’s stockholders approved the 2020 Incentive Award Plan (the “2020 Plan”), which allows for grants to selected employees, consultants and non-employee members of the Board of Directors. We currently grant stock options and restricted stock units (“RSUs”), under the 2020 Plan. The number of common shares available for issuance under the 2020 Plan is the sum of (1) 5,600,000 shares of common stock; plus (2) any shares forfeited from the unvested restricted shares of our common stock issued upon conversion of unvested Class B common units (up to 1,250,000 shares); plus (3) an annual increase on the first day of each fiscal year beginning with the fiscal year ending December 31, 2021 and continuing to, and including, the fiscal year ending December 31, 2030, equal to the lesser of (a) 5% of the shares of common

stock outstanding on the final day of the immediately preceding calendar year and (b) such smaller number of shares as determined by our Board of Directors.

At September 30, 2022, 7,723,355 shares were subject to outstanding awards under the 2020 Plan and 840,642 shares were available for future grants of share-based awards under the 2020 Plan.
In July 2022, the Company’s Board of Directors approved the Zentalis Pharmaceuticals, Inc. 2022 Employment Inducement Incentive Award Plan (the “2022 Inducement Plan”), which is used exclusively for the grant of equity awards to new employees as an inducement material to the employees’ entering into employment with the Company. The Board of Directors has initially reserved 1,500,000 shares of the Company’s common stock for issuance pursuant to awards granted under the 2022 Inducement Plan.
At September 30, 2022, 415,500 shares were subject to outstanding awards under the 2022 Inducement Plan and 1,084,500 shares were available for future grants of share-based awards under the 2022 Inducement Plan.

Stock Options and Restricted Stock Units
The exercise price of stock options granted is equal to the closing price of the Company’s common stock on the date of grant. The fair value of each option award is estimated on the date of grant using the Black-Scholes model. Due to the Company’s limited operating history and a lack of company specific historical and implied volatility data, the Company estimates expected volatility based on the historical volatility of a group of similar companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. The Company uses the “simplified method” for estimating the expected term of employee options, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years). The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The Company has not issued any dividends and does not expect to issue dividends over the life of the options. As a result, the Company has estimated the dividend yield to be zero.
