1. Business Description

G1 Therapeutics, Inc. (the “Company”) is a commercial-stage biopharmaceutical company based in Research Triangle Park, North Carolina focused on the development and commercialization of novel small molecule therapeutics for the treatment of patients with cancer. The Company’s first FDA-approved product, COSELA™ (trilaciclib) is the first and only therapy indicated to proactively help protect bone marrow from the damage of chemotherapy and is the first innovation in managing myelosuppression in decades. The Company was incorporated on May 19, 2008 in the state of Delaware.

Currently, the Company is advancing two clinical stage programs. Our lead compound trilaciclib is a first-in-class therapy designed to improve outcomes for patients who are treated with chemotherapy. Rintodestrant is an oral selective estrogen receptor degrader (SERD) for the potential treatment of ER+, HER2- breast cancer. In addition, the Company out-licensed global rights to lerociclib, an internally discovered and differentiated oral CDK4/6 inhibitor designed to enable more effective combination treatment strategies across multiple oncology indications.  The Company also has intellectual property focused on cyclin-dependent kinase targets.

Trilaciclib

The Company’s lead compound, trilaciclib, is a first-in-class therapy approved to help protect hematopoietic stem and progenitor cells (“HSPCs”) in bone marrow against chemotherapy-induced myelosuppression by transiently inhibiting CDK4/6 in patients with extensive-stage small cell lung cancer (“ES-SCLC”). This action leads to a temporary arrest of susceptible host cells during chemotherapy. This reduces the duration and severity of neutropenia and other myelosuppressive consequences of chemotherapy. Also, clinical trials have shown that trilaciclib has the potential to activate and enhance the immune system response driving increased anti-tumor efficacy, which the Company continue to explore in additional clinical trials. The Company is developing trilaciclib in a variety of clinical trials in tumors including colorectal cancer (“CRC”), metastatic triple negative breast cancer (“mTNBC”), neoadjuvant breast cancer, non-small cell lung cancer (“NSCLC”) and bladder cancer.

Trilaciclib is a novel therapeutic approach, which is given before chemotherapy, that temporarily blocks progression through the cell cycle. This provides two benefits. First, it proactively helps protect HSPCs in bone marrow leading to preservation of neutrophils, erythrocytes, and platelets (called myeloprotection) which reduces the occurrences and severity of neutropenia and other myelosuppressive consequences of chemotherapy. This myeloprotection benefit has been conclusively proven in double-blind placebo-controlled clinical trials in extensive-stage small cell lung cancer. Second, trilaciclib activates and enhances the immune system response driving increased anti-tumor efficacy, which the Company is exploring in clinical trials.

On February 12, 2021, COSELA for injection was approved by the U.S. Food and Drug Administration (“FDA”) to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for ES-SCLC. On March 2, 2021, COSELA became commercially available through G1’s specialty distributor network. COSELA is administered intravenously as a 30-minute infusion completed within four (4) hours prior to the start of chemotherapy and is the first FDA-approved therapy to provide proactive, multilineage protection from chemotherapy-induced myelosuppression. The approval of COSELA is based on data from three (3) randomized, placebo-controlled trials that showed patients receiving COSELA prior to chemotherapy had clinically meaningful and statistically significant reduction in the duration and severity of neutropenia, reduction of red blood cell transfusions, as well as improvements in other myeloprotection measures, compared to patients receiving chemotherapy without COSELA. G1 announced on March 25, 2021 that COSELA had been included in two updated National Comprehensive Cancer Network® (“NCCN”) Clinical Practice Guidelines in Oncology (NCCN Guidelines®): The Treatment Guidelines for Small Cell Lung Cancer and the Supportive Care Guidelines for Hematopoietic Growth Factors. These guidelines document evidence-based, consensus-driven management to ensure that all patients receive preventive, diagnostic, treatment, and supportive services that are most likely to lead to optimal outcomes.

In June 2020, the Company entered into a three-year co-promotion agreement for COSELA in the United States and Puerto Rico with Boehringer Ingelheim. The agreement is limited to support for SCLC. Under the terms of the agreement, the Company will book revenue in the United States and Puerto Rico and retain development and commercialization rights to trilaciclib. The Company will lead marketing, market access and medical engagement initiatives; Boehringer Ingelheim will lead sales force engagements.

In August 2020, the Company entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) for development and commercialization rights for trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau and Taiwan). Under the terms of the agreement, the Company received an upfront payment of $14.0 million in September 2020, and will be eligible to receive up to $156.0 million in development and commercial milestone payments. During the first quarter of 2021, the Company received two development milestone payments totaling $5.0 million. Simcere will also pay the Company tiered low double-digit royalties on annual net sales of trilaciclib in Greater China. As part of this agreement, Simcere will participate in global clinical trials of trilaciclib and the companies will be responsible for all development and commercialization costs in their respective territories.

5

The Company is also executing on its tumor-agnostic strategy to evaluate the potential benefits of providing trilaciclib to patients with other tumors that are treated with chemotherapy. The Company has three on-going clinical trials: a pivotal trial in 1L CRC, a pivotal trial in mTNBC (including 1L and 2L patients), and a Phase 2 trial in neoadjuvant breast cancer (I-SPY 2). The Company intends to initiate two additional Phase 2 studies: a 2L/3L NSCLC trial in post-checkpoint patients and a 1L bladder cancer trial with chemotherapy and a checkpoint inhibitor. These studies across treatment settings and tumor types will evaluate trilaciclib’s dual benefits in both multi-lineage myeloprotection and anti-tumor efficacy.

Rintodestrant

Rintodestrant is an oral selective estrogen receptor degrader (“SERD”) for the treatment of estrogen receptor-positive (“ER+”) breast cancer.  Rintodestrant, an oral SERD, is a Phase 2 compound being developed as a monotherapy and in combination with CDK4/6 inhibitors, initially Ibrance® (palbociclib), for the treatment of ER+ breast cancer. In 2018, the Company initiated a Phase 1/2a (dose escalation/dose expansion) clinical trial in ER+, HER2- breast cancer. Preliminary data from the Phase 1 portion of this trial were presented at the 2019 ESMO Congress, showing that rintodestrant was well tolerated and demonstrated evidence of anti-tumor activity in heavily pre-treated patients. The mature monotherapy data were presented at the 2020 San Antonio Breast Cancer Symposium (“SABCS”) conference, confirming the safety and efficacy results of the preliminary analysis. Based on these findings the Company advanced an 800 mg dose of rintodestrant into a 40-patient Phase 2 combination trial with palbociclib, a CDK4/6 inhibitor. The Company has completed enrollment of patients in this trial and expects to disclose initial safety and efficacy data in the second quarter of 2021. Palbociclib is being provided under a non-exclusive clinical supply agreement that was signed with Pfizer in February 2020. The Company will evaluate partnering options for rintodestrant following the data read-out from its combination study.

Lerociclib

Lerociclib is a differentiated clinical-stage oral CDK4/6 inhibitor for use in combination with other targeted therapies in multiple oncology indications. In 2020, the Company entered into separate, exclusive agreements with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside Asia-Pacific) and Genor Biopharma Co. Inc. (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. Combined, these agreements provided $26.0 million in upfront payments to the Company in 2020, and provide up to $330.0 million in potential milestone payments, plus sales-based royalties. EQRx, Inc. and Genor Biopharma Co. Inc. are responsible for all costs related to the development and commercialization of lerociclib in their respective territories.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations for the interim periods presented. 

The information presented in the condensed financial statements and related notes as of March 31, 2021, and for the three months ended March 31, 2021 and 2020, is unaudited. The results for the three months ended March 31, 2021 are not necessarily indicative of the results expected for the full fiscal year or any future period. These interim financial statements should be read in conjunction with the financial statements and notes set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 24, 2021, (the “2020 Form 10-K”). The December 31, 2020 condensed balance sheet included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including notes, required by U.S. GAAP for complete financial statements. Certain amounts have been reclassified to conform to current presentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. On an ongoing basis, the Company’s management evaluates its estimates which include, but are not limited to, estimates related to accrued expenses, accrued external clinical costs, net revenues, stock-based compensation expense and deferred tax asset valuation allowance.  The Company bases its estimates on historical experience and other market specific or other relevant assumptions it believes to be reasonable under the circumstances.  Actual results could differ from those estimates.

6

Accounts Receivable

The Company’s accounts receivable consists of amounts due from specialty distributors in the U.S. (collectively, its “Customers”) related to sales of COSELA and have standard payment terms. Trade receivables are recorded net of the estimated variable consideration for chargebacks based on contractual terms and the Company’s expectation regarding the utilization and earnings of the chargebacks and discounts as well as the net amount expected to be collected from the Company’s customers. Estimates of the Company’s credit losses are determined based on existing contractual payment terms, individual customer circumstances, and any changes to the economic environment.

In addition, the Company’s accounts receivable consists of open invoices issued to its license partners for services rendered by the Company or receivables with its license partners for invoices related to milestones that were completed and recognized as revenue.

Inventories

Inventories are stated at the lower of cost or net realizable value and recognized on a weighted-average cost method. The Company uses actual cost to determine the cost basis for inventory. Inventory is capitalized based on when future economic benefit is expected to be realized. Due to the nature of the Company’s supply chain process, inventory that is owned by the Company, is physically stored at third-party warehouses, logistics providers, and contract manufacturers. The Company began capitalizing inventory upon receiving FDA approval for COSELA on February 12, 2021. Prior to FDA approval of COSELA, expenses associated with the manufacturing of the Company's products were recorded as research and development expense.

Inventory valuation reserves are established based on a number of factors including, but not limited to, finished goods not meeting product specifications, product excess and obsolescence, or application of the lower of cost or net realizable value concepts. The determination of events requiring the establishment of inventory valuation reserves, together with the calculation of the amount of such reserves may require judgment. The Company analyzes its inventory levels on a periodic basis to determine if any inventory is at risk for expiration prior to sale or has a cost basis that is greater than its estimated future net realizable value. Any adjustments are recognized through cost of sales in the period in which they are incurred. No inventory valuation reserves have been recorded for any periods presented.

Revenue Recognition

For elements of those arrangements that the Company determines should be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company assesses which activities in its license or collaboration agreements are performance obligations that should be accounted for separately and determines the transaction price of the arrangement, which includes the assessment of the probability of achievement of future milestones and other potential consideration. For arrangements that include multiple performance obligations, such as granting a license or performing manufacturing or research and development activities, the Company allocates the transaction price based on the relative standalone selling price and recognizes revenue that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. Accordingly, the Company develops assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. These key assumptions may include revenue forecasts, clinical development timelines and costs, discount rates and probabilities of clinical and regulatory success.

License Revenue

Licenses of Intellectual Property

If a license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue associated with the bundled performance obligation. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of progress and related revenue recognition.

Milestone Payments

At the inception of each arrangement that includes developmental and regulatory milestone payments, the Company evaluates whether the achievement of each milestone specifically relates to the Company’s efforts to satisfy a performance obligation or transfer a distinct good or service within a performance obligation. The Company evaluates each milestone to determine when and how much of the milestone to include in the transaction price. The Company first estimates the amount of the milestone payment that the Company could receive using either the expected value or the most likely amount approach. The Company primarily uses the most likely

7

amount approach as that approach is generally most predictive for milestone payments with a binary outcome. Then, the Company considers whether any portion of that estimated amount is subject to the variable consideration constraint (that is, whether it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the uncertainty). The Company updates the estimate of variable consideration included in the transaction price at each reporting date which includes updating the assessment of the likely amount of consideration and the application of the constraint to reflect current facts and circumstances.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.

Product Sales, Net

The Company sells COSELA to specialty distributors in the U.S. and, in accordance with ASC 606, recognizes revenue at the point in time when the customer is deemed to have obtained control of the product. The customer is deemed to have obtained control of the product at the time of physical receipt of the product at the customers’ distribution facilities, or Free on Board (“FOB”) destination, the terms of which are designated in the contract.

Product sales are recorded at the net selling price, which includes estimates of variable consideration for which reserves are established for (a) rebates and chargebacks, (b) co-pay assistance programs, (c) distribution fees, (d) product returns, and (e) other discounts. Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as current contractual and statutory requirements, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of variable consideration may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company's estimates. If actual results in the future vary from estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variances become known.

Liabilities related to co-pay assistance, rebates, and GPO fees are classified as “Accrued Expenses” in the Condensed Balance Sheets. Discounts such as chargebacks, returns, and specialty distributor fees are recorded as a reduction to trade accounts receivable, which is included in “Accounts Receivable” in the Condensed Balance Sheets.

Forms of Variable Consideration

Rebates and Chargebacks: The Company estimates reductions to product sales for Public Health Service Institutions, such as Medicaid, Medicare and Veteran’' Administration (“VA”) programs, as well as certain other qualifying federal and state government programs, and other group purchasing organizations. The Company estimates these reductions based upon the Company’s contracts with government agencies and other organizations, statutorily defined discounts and estimated payor mix. These organizations purchase directly from the Company’s specialty distributors at a discount and the specialty distributors charge the Company back the difference between the wholesaler price and the discounted price. The Company’s liability for Medicaid rebates consists of estimates for claims that a state will make. The Company’s reserve for this discounted pricing is based on expected sales to qualified healthcare providers and the chargebacks that customers have already claimed.

Co-pay assistance: Eligible patients who have commercial insurance may receive assistance from the Company to reduce the patient’s out of pocket costs. Liabilities for co-pay assistance are calculated by actual program participation from third-party administrators.

Distribution Fees: The Company has written contracts with its customers that include terms for distribution fees and costs for inventory management. The Company estimates and records distribution fees due to its customers based on gross sales.

Product Returns: The Company generally offers a right of return based on the product’s expiration date and certain spoilage and damaged instances. The Company estimates the amount of product sales that may be returned and records the estimate as a reduction of product sales in the period the related product sales are recognized. The Company’s estimates for expected returns are based primarily on an ongoing analysis of sales information and visibility into the inventory remaining in the distribution channel.

Cost of Goods Sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of COSELA, including third-party manufacturing costs, packaging services, freight-in, third-party logistics costs associated with COSELA, and Company personnel costs. Cost of goods sold may also include period costs related to certain inventory manufacturing services and inventory adjustment

8

charges. In connection with the FDA approval of COSELA on February 12, 2021, the Company subsequently began capitalizing inventory manufactured or purchased after this date. As a result, certain manufacturing costs associated with product shipments of COSELA were expensed prior to FDA approval and, therefore, are not included in cost of goods sold during the current period.

Research and Development

Research and development expenses consist of costs incurred to further the Company’s research and development activities and include salaries and related employee benefits, manufacturing of pharmaceutical active ingredients and drug products, costs associated with clinical trials, nonclinical activities, regulatory activities, research-related overhead expenses and fees paid to expert consultants, external service providers and contract research organizations which conduct certain research and development activities on behalf of the Company. Costs incurred in the research and development of products are charged to research and development expense as incurred.

Each reporting period, management estimated and accrued research and development expenses, including external clinical study costs associated with clinical trial activities. The process of estimating and accruing expenses involves reviewing contracts and purchase orders, identifying services that have been provided on the Company’s behalf, and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been invoiced or otherwise notified of the actual costs.

Costs for clinical trial activities were estimated based on an evaluation of vendors’ progress towards completion of specific tasks, using data such as patient enrollment, clinical site activations or information provided by vendors regarding their actual costs incurred. Payments for these activities are based on the terms of individual contracts and payment timing may differ significantly from the period in which the services were performed. The Company determines accrual estimates through reports from and discussions with applicable personnel and outside service providers as to the progress or state of completion of trials, or the services completed. The estimates of accrued external clinical study costs as of each balance sheet date are based on the facts and circumstances known at the time.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of March 31, 2021 and December 31, 2020, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of operations. As of March 31, 2021 and December 31, 2020, the Company had no such accruals.

Income tax expense recognized during the three months ended March 31, 2021 related to the foreign withholding taxes incurred as a result of the Simcere milestone payments received during the period. See Note 11 for further detail.

Stock-Based Compensation

The primary type of stock-based payments utilized by the Company are stock options. The Company accounts for stock-based employee compensation arrangements by measuring the cost of employee services received in exchange for all equity awards granted based on the fair value of the award on the grant date. The fair value of each employee stock option is estimated on the date of grant using an options pricing model. The Company currently uses the Black-Scholes valuation model to estimate the fair value of its share-based payments. The model requires management to make a number of assumptions including expected volatility, expected life, risk-free interest rate and expected dividends.

The Company also incurs stock-based compensation expense related to restricted stock units (“RSUs”) granted to employees. The fair value of RSUs is determined by the closing market price of the Company’s common stock on the date of grant and then recognized over the requisite service period of the award.

9

Debt Issuance Costs

Debt issuance costs are amortized to interest expense over the estimated life of the related debt based on the effective interest method. In accordance with ASC 835, Interest, the Company presents debt issuance costs on the condensed balance sheet as a direct deduction from the associated debt.

Coronavirus (COVID-19) Impact on Operations

The Company has implemented business continuity plans to address the COVID-19 pandemic and minimize disruptions to ongoing operations. Enrollment of patients in current and future clinical trials may be impacted by COVID-19. The Company does not anticipate significant supply chain delays or shortages as a result of the COVID-19 pandemic. COVID-19 travel limitations and government-mandated work-from-home or shelter-in-place orders, may reduce the number of in-person meetings with prescribers and fewer patient visits with physicians, potentially resulting in fewer new prescriptions.

The Company established a COVID-19 response team which continually monitors the impact of COVID-19 on its operations.  The COVID-19 response team manages workplace protocols that govern employees use of the Company’s office. To mitigate the impact of COVID-19 on its business, the Company put in place the following safety measures for its employees, patients, healthcare professionals, and suppliers to limit exposure: the Company substantially restricted travel, supplied personal protective equipment to employees, limited access to its headquarters and asked most of its staff to work remotely. In addition, the Company added bandwidth and VPN capacity to its infrastructure to facilitate remote work arrangements. The Company will continue to monitor the impact of COVID-19 on its operations and report its Board of Directors regularly on the progress of its response to the COVID-19 outbreak.

3. Fair Value Measurements

The Company provides disclosure of financial assets and financial liabilities that are carried at fair value based on the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements may be classified based on the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities using the following three levels:

The carrying amounts of cash, cash equivalents, accounts payable and accrued liabilities approximate fair value because of their short-term nature.

At March 31, 2021 and December 31, 2020 these financial instruments and respective fair values have been classified as follows (in thousands):

10

During the three months ended March 31, 2021 and the year ended December 31, 2020, there were no changes in valuation methodology.

The Loan Payable (discussed in Note 8), which is classified as a Level 3 liability, has a variable interest rate and the carrying value approximates its fair value. As of March 31, 2021, the carrying value was $29.9 million.

4. Inventories

Inventories as of March 31, 2021 and December 31, 2020 consist of the following (in thousands):

The Company uses third party contract manufacturing organizations for the production of its raw materials, active pharmaceutical ingredients, and finished drug product which the Company owns. Costs incurred by the Company for manufacturing of initial commercial product of COSELA in preparation of commercial launch were expensed prior to FDA approval.

5. Property and Equipment

Property and equipment consists of the following (in thousands):

Depreciation expense relating to property and equipment was $120 thousand and $159 thousand for the three months ended March 31, 2021 and March 31, 2020, respectively. 

6. Patent License Agreement

On November 23, 2016, the Company entered into a license agreement with the Board of Trustees of the University of Illinois (“the University”), which was amended on March 24, 2017.  Pursuant to the license agreement, as amended, the University licensed patent

11

rights to the Company, with rights of sublicense, to make, have made, use, import, sell and offer for sale products covered by certain patent rights owned by the University. The rights licensed to the Company are exclusive, worldwide, non-transferable rights, for all fields of use. Under the terms of the agreement the Company paid a one-time only, non-refundable license issue fee in the amount of $0.5 million which was charged to research and development expense in the fourth quarter of 2016.

The Company is also obligated to pay annual maintenance fees to the University. All annual minimum payments are fully creditable against any royalty payments made by the Company. Under the terms of the agreement, the Company must pay the University a royalty percentage on all net sales of products and a share of sublicensing revenues. In addition, the University is eligible to receive milestone payments of up to $2.6 million related to the initiation and execution of clinical trials and the first commercial sale of a product in another country. To date, the Company has made milestone payments totaling $0.6 million, of which $0 million was incurred during the current quarter. The Company will be responsible for any future patent prosecution costs that may arise.

The term of the license agreement will continue until the later of (i) the expiration of the last valid claim within the patent rights covering the product in such country, (ii) the expiration of market exclusivity in such country and (iii) the 10th anniversary of the first commercial sale in such country. The University may terminate the agreement in the event (i) the Company fails to pay any amount or make any report when required to be made and fails to cure such failure within thirty (30) days after receipt of notice from the University, (ii) is in breach of any provision of the agreement and fails to remedy within forty-five (45) days after receipt of notice, (iii) makes a report to the University under the agreement that is determined to be materially false, (iv) declares insolvency or bankruptcy or (v) takes an action that causes patent rights or technical information to be subject to lien or encumbrance and fails to remedy any such breach within forty-five (45) days of receipt of notice from the University. The Company may terminate the agreement at any time on written notice to the University at least ninety (90) days prior to the termination date specified in the notice. Upon expiration or termination of the agreement, all rights revert to the University.

7. Accrued Expenses

Accrued expenses are comprised as follows (in thousands):

8. Loan Payable

On May 29, 2020, the Company entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (“Hercules”), under which Hercules has agreed to lend the Company up to $100.0 million, to be made available in a series of tranches, subject to certain terms and conditions. The first tranche totals $30.0 million, of which the Company received $20.0 million at closing. Upon initiation of the phase 3 trial of COSELA for metastatic colorectal cancer and receiving FDA approval for COSELA for small cell lung cancer (“the Performance Milestone”), the second tranche of $20.0 million became available to the Company for drawdown through December 15, 2021. The third tranche of $30.0 million will be available through December 31, 2022. The fourth tranche of $20.0 million will be available at Hercules’ approval through December 31, 2022. On March 31, 2021, the Company entered into the First Amendment to Loan and Security Agreement (the “First Amendment”) with Hercules whereby the Company drew the remaining $10.0 million of the first tranche and the interest rate and financial covenants were amended. Unless loan advances by the Company exceed $40.0 million, no financial covenants are required. As of March 31, 2021, no financial covenants apply as the Company had only drawn down on the first tranche.

Amounts borrowed under the original Loan Agreement will bear an interest rate equal to the greater of either (i) (a) the prime rate as reported in The Wall Street Journal, plus (b) 6.40%, and (ii) 9.65%. Based on original terms of the Loan Agreement, the Company will make interest only payments through June 1, 2022 and following the interest only period, the Company will repay the principal balance and interest of the advances in equal monthly installments through June 1, 2024. Based on the original terms of the Loan Agreement, upon satisfaction of the Performance Milestone, the interest only period was extended through January 1, 2023 and the maturity date was extended to June 1, 2025. Upon entering into the First Amendment on March 31, 2021, the interest rate was

12

amended to be equal to the greater of either (i) (a) the prime rate as reported in The Wall Street Journal, plus (b) 6.20%, and (ii) 9.45%.

The Company may prepay advances under the Loan Agreement, in whole or in part, at any time subject to a prepayment charge equal to (a) 3.0% of the prepayment amount in the first year; (b) 2.0% of the prepayment amount in the second year; and (c) 1.0% of the prepayment amount in the third year.

Upon prepayment or repayment of all or any of the advances under the Loan Agreement, the Company will pay (in addition to the prepayment charge) an end of term charge of 6.95% of the aggregate funded amount. With respect to the first tranche, the end of term charge of $2.1 million will be payable upon any prepayment or repayment. To the extent that the Company is provided additional advances under the Loan Agreement, the 6.95% end of term charge will be applied to such additional amounts. These amounts will be accrued over the term of the loan using effective-interest method.

The Loan Agreement is secured by substantially all of the Company’s assets, including intellectual property, subject to certain exemptions. The Company out-licensed lerociclib as permitted in the Loan Agreement and the Company may out-license rintodestrant upon approval of the licensing terms by Hercules.

The Company incurred financing expenses of $0.4 million related to the Loan Agreement which are recorded as debt issuance costs and as a direct reduction to long-term debt on the Company’s unaudited condensed balance sheet. Upon issuance, the Company treated $0.2 million of the upfront facility fee that related to the initial $20.0 million drawn as a debt discount and treating it in the same way as debt issuance costs. The remainder of the facility fee is related to future undrawn tranches and is accounted for as a deferred financing charge. Upon entering into the First Amendment, the Company incurred additional financing expenses of $0.1 million which were recorded as debt issuance costs. Also, in conjunction with the First Amendment, $0.1 million of the upfront facility fee previously recorded as a deferred financing charge was reclassified as a debt issuance cost since that amount related to the remainder of the first tranche which was drawn at the amendment date.

Upon issuance, the first tranche was recorded as a liability with an initial carrying value of $19.4 million, net of debt discount and debt issuance costs. Upon entering into the First Amendment, the carrying value increased by $9.8 million, net of debt discount and debt issuance costs. The carrying value is accreted to the repayment amount, which includes the outstanding principal plus the end of term charge, through interest expense using the effective-interest method over the term of the debt. During the three months ended March 31, 2021, the Company recognized $0.7 million of interest expense related to the Loan Agreement, which is reflected in other income (expense), net on the unaudited condensed statements of operations.

As of March 31, 2021 the carrying value due under the Loan Agreement, excluding interest, is as follows:

9. Stockholders’ Equity

Common Stock

The Company is authorized to issue 120.0 million shares of common stock. Holders of common stock are entitled to one vote per share.  Holders of common stock are entitled to receive dividends, as, if and when declared by the Company’s Board of Directors.

Shares Reserved for Future Issuance

The Company has reserved authorized shares of common stock for future issuance at March 31, 2021 and December 31, 2020 as follows:

10. Stock-Based Compensation

2011 Equity Incentive Plan

In March 2011, the Company adopted the 2011 Equity Incentive Plan (the “2011 Plan”). The 2011 Plan provided for the direct award or sale of the Company’s common stock and for the grant of stock options to employees, directors, officers, consultants and advisors of the Company.  The 2011 Plan was subsequently amended in August 2012, October 2013, February 2015, December 2015, April 2016 and November 2016 to allow for the issuance of additional shares of common stock.  In connection with the adoption of the 2017 Plan (as defined below), the 2011 Plan was terminated and no further awards will be made under the 2011 Plan.

2017 Equity Incentive Plan

In May 2017, the Company adopted the 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan provided for the direct award or sale of the Company’s common stock and for the grant of up to 1,932,000 stock options to employees, directors, officers, consultants and advisors of the Company.  The 2017 Plan provides for the grant of incentive stock options, non-statutory stock options or restricted stock.  Effective January 1, 2021, and in accordance with the “evergreen” provision of the 2017 Plan, an additional 1,096,553 shares were made available for issuance.

Under both the 2011 Plan and the 2017 Plan, options to purchase the Company’s common stock may be granted at a price no less than the fair market value of a share of common stock on the date of grant.  The fair value shall be the closing sales price for a share as quoted on any established securities exchange for such grant date or the last preceding date for which such quotation exists.  Vesting terms of options issued are determined by the Board of Directors or Compensation Committee of the Board.  The Company’s stock options vest based on terms in the stock option agreements.  Stock options have a maximum term of ten years.

Beginning in January 2021, the Company began granting Restricted Stock Units (“RSUs”) under the 2017 Plan. RSUs are granted at the fair market value of a share of common stock on the date of grant.

As of March 31, 2021, there were a total of 657,309 shares of common stock available for future issuance under the 2017 Plan

2021 Inducement Equity Incentive Plan

In February 2021, the Company adopted the 2021 Inducement Equity Incentive Plan (the “2021 Inducement Plan”). The 2021 Inducement Plan provides for the grant of up to 500,000 non-qualified options, stock grants, and stock-based awards to employees and directors of the Company. The 2021 Inducement Plan does not include an evergreen provision.

14

As of March 31, 2021, there were a total of 485,700 shares of common stock available for future issuance under the 2021 Inducement Plan.    

Stock-Based Compensation

The Company recognizes compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The grant date fair value of the stock-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.  Share-based awards granted to non-employee directors as compensation for serving on the Company’s Board of Directors are accounted for in the same manner as employee share-based compensation awards.  

The Company calculates the fair value of stock options using the Black-Scholes option pricing model.  The Black-Scholes option-pricing model requires the use of subjective assumptions, including the expected volatility of the Company’s common stock, the assumed dividend yield, the expected term of the Company’s stock options and the fair value of the underlying common stock on the date of grant.

The Company also incurs stock-based compensation expense related to RSUs. The fair value of RSUs is determined by the closing market price of the Company’s common stock on the date of grant and then recognized over the requisite service period of the award.

The table below summarizes the stock-based compensation expense recognized in the Company’s statement of operations by classification (in thousands):

Stock options— Black-Scholes inputs

The fair value of stock options was estimated using the following weighted-average assumptions for the three months ended March 31, 2021 and March 31, 2020:

Stock Option Activity

15

The following table is a summary of the Stock option activity for the three months ended March 31, 2021:

As of March 31, 2021, unrecognized compensation expense related to unvested stock options totaled $45.2 million , which the Company expects to be recognized over a weighted-average period of approximately 2.6 years.

Restricted Stock Units

The Company’s restricted stock units (“RSUs”) are considered nonvested share awards and require no payment from the employee. For each RSU, employees receive one common share at the end of the vesting period. Compensation cost is recorded based on the market price of the Company’s common stock on the grant date and is recognized on a straight-line basis over the requisite service period.

16

The following table is a summary of the RSU activity for three months ended March 31, 2021:

As of March 31, 2021, there was $7.8 million of total unrecognized compensation cost related to Company RSUs that are expected to vest. These costs are expected to be recognized over a weighted-average period of approximately 3.3 years.

EQRx will be responsible for the development of the product in the EQRx Territory. The Company will continue until completion, as the clinical trial sponsor, its two primary clinical trials at EQRx’s sole cost and expense. EQRx will reimburse the Company for all of its out-of-pocket costs incurred after the effective date of the license agreement in connection with these clinical trials. The Company will invoice EQRx within 30 days following the end of the quarter, and EQRx will pay within 30 days after its receipt of such invoice.

17

For the three months ended March 31, 2021 the Company recognized revenue of $4.6 million related to the delivery of clinical drug supply and manufacturing services and $0.8 million for the reimbursement of costs associated with the two primary clinical trials for lerociclib. The amounts for clinical drug supply and manufacturing services have been invoiced and paid. The amounts for clinical trial reimbursements are recognized as accounts receivable on the balance sheet as of March 31, 2021. No development and commercial milestones, as defined by the agreement, have been achieved through March 31, 2021.

Simcere License Agreement

On August 3, 2020, the Company entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) for the development and commercialization of trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau, and Taiwan) (the “Simcere Territory”). Under the license agreement, the Company granted to Simcere an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals for, and commercialize trilaciclib in the Simcere Territory.

Under the license agreement, Simcere agreed to pay the Company a non-refundable, upfront cash payment of $14.0 million with the potential to pay an additional $156.0 million upon reaching certain development and commercial milestones. In addition, Simcere will pay the Company tiered low double-digit royalties on annual net sales of trilaciclib in the Simcere Territory. In accordance with ASC 606, the Company recognized the non-refundable, upfront cash payment of $14.0 million (less applicable withholding taxes of $1.4 million) in 2020 as the Company had transferred the license and related technology and know-how to Simcere.

Further, during the three months ended March 31, 2021, the Company recognized $5.0 million related to development milestones which were met during the period. As of March 31, 2021, cash was received for both development milestones.

12. Net Loss per Common Share

Basic net loss per common share is computed using the weighted average number of common shares outstanding during the period including nominal issuances of common stock warrants. Diluted net loss per common share is computed using the sum of the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options, stock warrants and unvested restricted common stock. For the three months ended March 31, 2021 and 2020 the following potentially dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding because the effect would be anti-dilutive:

Amounts in the table above reflect the common stock equivalents of the noted instrument.

13. Income Taxes

The Company’s effective income tax rate was (0.5)% and 0% for the three months ended March 31, 2021 and 2020, respectively. The Company continues to recognize losses in the United States and therefore, has recorded no tax benefit associated with these losses. The only income tax expense recognized related to the foreign withholding taxes incurred as a result of the Simcere licensing agreement. See Note 11 for further discussion on this transaction.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes included elsewhere in this quarterly report. This discussion and other parts of this quarterly report contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of our 2020 Form 10-K, and in our subsequently filed Quarterly Reports on Form 10-Q, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a commercial-stage biopharmaceutical company focused on the development and commercialization of novel small molecule therapeutics for the treatment of patients with cancer. Our first approved product by the U.S. Food and Drug Administration (“FDA”), COSELA™ (trilaciclib), is the first and only therapy indicated to proactively help protect bone marrow from the damage of chemotherapy and is the first innovation in managing myeloprotection in decades. COSELA was developed from a technology platform that targets key cellular pathways including transient arrest of the cell cycle at G1, prior to the beginning of DNA replication. Our therapies are designed to improve outcomes for patients across multiple oncology indications.

We shall use “COSELA” when we are referring to our FDA approved drug and “trilaciclib” when we are referring to our development of COSELA for additional indications.  

Product Pipeline

Trilaciclib is a first-in-class therapy designed to help protect against chemotherapy-induced myelosuppression. Trilaciclib helps protect HSPCs in bone marrow by transiently inhibiting CDK4/6 leading to a temporary arrest of susceptible host cells during chemotherapy in ES-SCLC patients.  This reduces the duration and severity of neutropenia and other myelosuppressive consequences of chemotherapy. In addition, trilaciclib activates and enhances the immune system response driving increased anti-tumor efficacy, which we continue to explore in clinical trials.

On February 12, 2021, COSELA was approved by the FDA to decrease the incidence of chemotherapy-induced myelosuppression in adult patients treated with a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive stage small cell lung cancer (“ES-SCLC”). We are also exploring potential use of trilaciclib in a variety of tumors, including colorectal cancer (“CRC”), metastatic triple negative breast cancer (“mTNBC”), neoadjuvant breast cancer, non-small cell lung cancer (“NSCLC”), and bladder cancer.

Rintodestrant is an oral selective estrogen receptor degrader (“SERD”) for the treatment of ER+ breast cancer. In 2020, we out-licensed global rights to lerociclib, an internally discovered and differentiated oral CDK4/6 inhibitor designed to enable more effective combination treatment strategies across multiple oncology indications.  We also have intellectual property focused on cyclin-dependent kinase targets.

Trilaciclib helps protect HSPCs in bone marrow by transiently inhibiting CDK4/6 leading to a temporary arrest of susceptible host cells during chemotherapy in ES-SCLC patients.  This reduces the duration and severity of neutropenia and other myelosuppressive consequences of chemotherapy. In addition, trilaciclib has demonstrated immune system response enhancement which we are exploring in clinical trials to show increased anti-tumor efficacy.

Trilaciclib, a transient IV CDK4/6 inhibitor, is a novel therapeutic approach which is given before chemotherapy that temporarily blocks progression through the cell cycle. This provides two benefits. First, it proactively helps protect HSPCs in bone marrow leading to preservation of neutrophils, erythrocytes, and platelets (called myeloprotection) which reduces the occurrences and severity of neutropenia and other myelosuppressive consequences of chemotherapy. This myeloprotection benefit has been conclusively proven in double-blind placebo-controlled clinical trials in extensive-stage small cell lung cancer. Second, trilaciclib activates and enhances the immune system response driving increased anti-tumor efficacy, which we are exploring in clinical trials. Our randomized clinical trials have demonstrated that trilaciclib can provide myeloprotection benefits and has the potential to improve survival as a result of its anti-tumor efficacy benefit.

Chemotherapy is an effective and important weapon against cancer. However, chemotherapy does not differentiate between healthy cells and cancer cells and kills both, including important stem cells in the bone marrow (namely, HSPCs) that produce white blood cells, red blood cells and platelets, and immune cells. This chemotherapy-induced bone marrow damage is known as myelosuppression. When white blood cells, red blood cells and platelets become depleted, chemotherapy patients are at increased risk of infection, experience anemia and fatigue, and are at increased risk of bleeding. Myelosuppression often requires the administration of rescue interventions such as growth factors and blood or platelet transfusions and may also result in chemotherapy dose delays and reductions. Immune cell damage may decrease the ability of the immune system to fight the cancer, as well as infection.

In preclinical studies, administration of trilaciclib prior to chemotherapy has been shown to induce transient cell-cycle arrest of HSPCs, helps protect HSPCs from chemotherapy-induced damage, preserve bone marrow and immune system function, helps protect against bone marrow exhaustion, improve complete blood counts (“CBC”) recovery, prevent myeloid skewing and consequent lymphopenia, and enhance T-cell effector function in the tumor microenvironment.

Following evaluation of trilaciclib in a Phase 1 trial in healthy volunteers, we initiated two Phase 1b/2 trials in patients with ES-SCLC; one in a first line setting (in combination with carboplatin/etoposide) and the other in a second-/third-line setting (in combination with topotecan). Enrollment in both trials has been completed and preliminary data from the open label Phase 1b segment were reported in

22

2016 and 2017. In the Phase 1b segments of these two trials, we treated 51 patients with over 250 cycles of trilaciclib and chemotherapy. There were no episodes of febrile neutropenia – one of the most common adverse consequences of these chemotherapy regimens. Further, there were no drug-related serious adverse events reported during the Phase 1b segments of these two trials. There were some adverse events reported involving fatigue and cytopenias, but those adverse events were less severe and less frequent than those generally reported in trials involving the use of chemotherapy alone.

Based on these encouraging preliminary data, we advanced both SCLC trials into the randomized, placebo-controlled, double-blind Phase 2 segment. Enrollment in the first-line SCLC Phase 2 trial was completed in the second quarter of 2017 and positive multilineage myeloprotection results were reported in March 2018, with additional data reported at the European Society for Medical Oncology (“ESMO”) 2018 Congress and published in Annals of Oncology in 2019. Enrollment in the second-/third-line SCLC Phase 2 trial was completed in the second quarter of 2018, with positive multilineage myeloprotection data reported in the fourth quarter of 2018 and full data presented at an oral session at the American Society of Clinical Oncology (“ASCO”) 2019 Annual Meeting. These data were also published in Advances in Therapy (Hart et al.) in 2020.

Our third trial in SCLC was initiated in 2017, as part of our non-exclusive collaboration with Genentech, with the goal of exploring the use of trilaciclib in combination with chemotherapy and a checkpoint inhibitor.  The trial was a randomized, placebo-controlled, double-blind Phase 2 trial of trilaciclib in combination with Tecentriq® (atezolizumab)/carboplatin/etoposide in first-line SCLC patients. We completed enrollment in February 2018 and reported positive multilineage myeloprotection data in November 2018. Additional data, including myeloprotection and anti-tumor efficacy findings as measured by overall survival (“OS”), were reported at the 2019 ESMO Congress and featured in a concurrent publication in The Lancet Oncology.

All three SCLC trials demonstrated that trilaciclib, when added to standard of care chemotherapy or chemotherapy/checkpoint inhibitor regimens, decreases the incidence of clinically significant chemotherapy-induced myelosuppression. The FDA granted Breakthrough Therapy Designation for trilaciclib based on myeloprotection data from our three randomized, double-blind, placebo-controlled SCLC clinical trials, as well as safety data collected across all completed and ongoing clinical trials. The Breakthrough Therapy program is designed to expedite development and review of drugs intended for serious or life-threatening conditions. In August 2020, the FDA accepted our New Drug Application (“NDA”) for trilaciclib in SCLC, granting Priority Review with a Prescription Drug User Fee Act (“PDUFA”) action date of February 15, 2021. Discussions with European regulatory authorities have indicated existing data is sufficient to support a Marketing Authorization Application (“MAA”) to the European Medicines Agency (“EMA”) for trilaciclib for myeloprotection in SCLC, which we plan to pursue in collaboration with a partner.

On February 12, 2021, COSELA™ was approved by the FDA to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive-stage small cell lung cancer (“ES-SCLC”). COSELA became commercially available through G1’s specialty distributor network on March 2, 2021. COSELA is administered intravenously as a 30-minute infusion completed within four (4) hours prior to the start of chemotherapy and is the first and only FDA-approved therapy that helps proactively deliver multilineage myeloprotection to patients with ES-SCLC being treated with chemotherapy. The approval of COSELA is based on data from three (3) randomized, placebo-controlled trials that showed patients receiving COSELA prior to chemotherapy had clinically meaningful and statistically significant reduction in the duration and severity of neutropenia, reduction of red blood cell transfusions, as well as improvements in other myeloprotection measures, compared to patients receiving chemotherapy without COSELA. G1 announced on March 25, 2021 that COSELA had been included in two updated National Comprehensive Cancer Network® (“NCCN”) Clinical Practice Guidelines in Oncology (NCCN Guidelines®): The Treatment Guidelines for Small Cell Lung Cancer and the Supportive Care Guidelines for Hematopoietic Growth Factors. These guidelines document evidence-based, consensus-driven management to ensure that all patients receive preventive, diagnostic, treatment, and supportive services that are most likely to lead to optimal outcomes.

In June 2020, we entered into a three-year co-promotion agreement for COSELA™ (trilaciclib) in the United States and Puerto Rico with Boehringer Ingelheim. The agreement is limited to support for SCLC. Under the terms of the agreement, we will book revenue in the United States and Puerto Rico and retain development and commercialization rights to trilaciclib. We will lead marketing, market access and medical engagement initiatives; Boehringer Ingelheim will lead sales force engagements.

In August 2020, we entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) for development and commercialization rights for trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau and Taiwan). Under the terms of the agreement, we received an upfront payment of $14.0 million and will be eligible to receive up to $156.0 million in development and commercial milestone payments. Simcere will also pay us tiered low double-digit royalties on annual net sales of trilaciclib in Greater China. As part of the agreement, Simcere will participate in global clinical trials of trilaciclib and the companies will be responsible for all development and commercialization costs in their respective territories.

We are also executing on our tumor-agnostic strategy to evaluate the potential benefits of trilaciclib to patients with other tumors that are treated with chemotherapy. We have three ongoing clinical trials: a pivotal trial in 1L colorectal cancer (“CRC”), a pivotal trial in mTNBC (including 1L and 2L patients), and a Phase 2 trial in neoadjuvant breast cancer (“I-SPY 2”). We intend to initiate two additional Phase 2 studies: a 2L/3L non-small cell lung cancer (“NSCLC”) trial in post-checkpoint patients and a 1L bladder cancer

23

trial with chemotherapy and a checkpoint inhibitor. These studies across treatment settings and tumor types will evaluate trilaciclib’s dual benefits in both multi-lineage myeloprotection and anti-tumor efficacy.

Pivotal 1L Colorectal Cancer (“CRC”)

We are enrolling patients in a randomized, placebo-controlled registrational trial of trilaciclib in CRC in the first quarter of 2021. CRC is a large indication commonly treated with 5-FU-based chemotherapy. We have extensive preclinical research demonstrating myeloprotection and potential efficacy in 5-FU-based regimens with trilaciclib. Our ongoing 1L CRC trial is with FOLFOXIRI, which is the most efficacious chemo regimen in this tumor but is also highly myelosuppressive. By reducing the toxicity of FOLFOXIRI, we believe we will significantly expand its use in CRC and potentially improve overall survival.

1L/2L Metastatic Triple-Negative Breast Cancer (“mTNBC”)

In 2017, we initiated a randomized Phase 2 trial of trilaciclib in patients with first-/second-/third-line mTNBC receiving gemcitabine (“GC”) and carboplatin.  Enrollment was completed in the second quarter of 2018. At the 2018 SABCS, we presented preliminary trilaciclib data demonstrating improvement in progression-free survival (“PFS”). In September 2019, we presented updated data demonstrating significant improvement in OS (preliminary). Though the trial did not meet the primary myeloprotection endpoints, patients receiving trilaciclib were able to receive approximately 50% more cycles of chemotherapy, without additional hematological toxicity. These data were presented at the 2019 ESMO Congress and were concurrently published in The Lancet Oncology. Updated safety and efficacy data from this trial were presented at the 2020 SABCS. Data included that compared to GC alone (Group 1), OS was improved in both trilaciclib arms (Groups 2 and 3) (Group 2: HR=0.31, p=0.0016; Group 3: HR=0.40, p=0.0004). Median OS was 12.6 months in Group 1, not reached for Group 2, and 17.8 months in Group 3. The median OS for Groups 2 and 3 combined was 19.8 months (HR=0.37, p<0.0001). OS findings in patients receiving trilaciclib were consistent with previously reported data from this trial. The median OS for GC alone (Group 1, 12.6 months) was consistent with the previous trial findings and historical data. Patients with both PD-L1-positive and PD-L1-negative tumors treated with trilaciclib and GC demonstrated improvement in OS compared to patients receiving GC alone, with the PD-L1-positive subset achieving statistically significant improvement. Further, data from T cell clonality analyses suggest that administering trilaciclib prior to chemotherapy enhanced immune system function. These compelling Phase 2 data supported the potential effectiveness of trilaciclib in mTNBC.

On April 28, 2021, G1 announced the initiation of PRESERVE 2, a pivotal Phase 3, randomized, double-blind, placebo-controlled study of COSELA™ (trilaciclib) in patients receiving first- or second-line gemcitabine and carboplatin chemotherapy for locally advanced unresectable or metastatic triple-negative breast cancer. PRESERVE 2 will evaluate the survival benefit of COSELA in 250 patients with locally advanced unresectable or metastatic TNBC. PRESERVE 2 will enroll two cohorts of patients. Cohort 1 (n=170) will evaluate patients receiving first-line therapy, regardless of PD-L1 status, who are PD-1/PD-L1 inhibitor-naïve. Cohort 2 (n=80) will evaluate PD-L1 positive patients receiving second-line therapy following prior PD-1/PD-L1 inhibitor therapy in the locally advanced unresectable/metastatic setting.

Phase 2 Neoadjuvant Breast Cancer (I-SPY 2)

Trilaciclib is included in a randomized, investigational treatment arm for the ongoing I-SPY 2 TRIAL™ for neoadjuvant treatment of locally advanced breast cancer. The trial, initiated in the second quarter of 2020 and run by the non-profit Quantum Leap Healthcare Collaborative, is designed to rapidly screen promising experimental treatments and identify those most effective in specific patient subgroups based on molecular characteristics (biomarker signatures). This trial will generate myeloprotection and anti-tumor efficacy data across the different subtypes of breast cancer.

2L/3L Non-Small Cell Lung Cancer (“NSCLC”)

We intend to initiate a multicenter randomized, double blind, placebo controlled Phase 2 study of COSELA™ (trilaciclib) in post-checkpoint patients with metastatic NSCLC in the second quarter of 2021 treated with docetaxel in the 2nd  and 3rd line setting. Myeloprotection and anti-tumor efficacy endpoints will be assessed in this study. We believe that evaluating trilaciclib in 2L/3L NSCLC (post-checkpoint setting) will provide us with meaningful data in an area of high unmet need with a large patient population. NSCLC is a known immunogenic tumor which may provide trilaciclib an opportunity to increase anti-tumor efficacy through its distinct mechanism even after checkpoint inhibitors have failed. There is also a highly complementary commercial fit with our initial SCLC indication.

1L Bladder Cancer

We intend to initiate a 1L bladder cancer trial in the first half of 2021 with chemotherapy and a checkpoint inhibitor. There is a strong rationale to evaluate trilaciclib in 1L bladder cancer: (1) bladder is a known immunogenic tumor proven to be responsive to

24

chemotherapy; (2) the most common chemotherapy regimen used in 1L bladder is gemcitabine and platinum, which is similar to the chemotherapy regimen in our mTNBC study (gemcitabine and carboplatin) where we showed significant OS benefits; and (3) we have observed synergistic benefits combining trilaciclib with checkpoints. G1 announced in February 2021 that it had entered into a clinical trial collaboration with the alliance between Merck KGaA, Darmstadt, Germany and Pfizer whereby the alliance will contribute clinical supply of the checkpoint inhibitor avelumab to this G1-sponsored and funded trial.

Rintodestrant

Rintodestrant is a clinical-stage oral SERD, for use as a monotherapy and in combination with CDK4/6 inhibitors, initially Ibrance® (palbociclib), for the treatment of ER+, HER2- breast cancer. Based on compelling preclinical efficacy and safety data, we filed an Investigational New Drug application (“IND”) with the FDA in the fourth quarter of 2017. In 2018, we initiated a Phase 1/2a (dose escalation/dose expansion) clinical trial in ER+, HER2- breast cancer. Preliminary data from the Phase 1 portion of this trial were presented at the 2019 ESMO Congress, showing that rintodestrant was well tolerated and demonstrated evidence of anti-tumor activity in heavily pre-treated patients. The mature monotherapy data were presented at the 2020 SABCS conference, confirming the safety and efficacy results of the preliminary analysis. Based on these findings the Company advanced an 800 mg dose of rintodestrant into a 40-patient Phase 2 combination trial with palbociclib, a CDK4/6 inhibitor. We completed enrollment of patients receiving rintodestrant in combination with palbociclib in October 2020 and expect to disclose initial safety and efficacy data in the second quarter of 2021. Palbociclib is being provided under a non-exclusive clinical supply agreement that we signed with Pfizer in February 2020. We will evaluate partnering options for rintodestrant following the data read-out from our combination study.

Lerociclib

Lerociclib is a differentiated oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in multiple oncology indications. In 2020, we entered into separate, exclusive agreements with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside Asia-Pacific) and Genor Biopharma Co. Inc. (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. Combined, these agreements provided $26.0 million in upfront payments, along with sales-based royalties and up to $330.0 million in potential milestone payments. EQRx, Inc. and Genor Biopharma Co. Inc. are responsible for all costs related to the development and commercialization of lerociclib in their respective territories.

Coronavirus (COVID-19) impact on operations

We have implemented business continuity plans to address the COVID-19 pandemic and minimize disruptions to ongoing operations. Enrollment of patients in current and future clinical trials may be impacted by COVID-19. We do not anticipate significant supply chain delays or shortages as a result of the COVID-19 pandemic. COVID-19 travel limitations and government-mandated work-from-home or shelter-in-place orders, may reduce the number of in-person meetings with prescribers and fewer patient visits with physicians, potentially resulting in fewer new prescriptions.

We established a COVID-19 response team which continually monitors the impact of COVID-19 on our operations.  The COVID-19 response team manages our workplace protocols that governs our employees’ use of our office. To mitigate the impact of COVID-19 on our business, we put in place the following safety measures for our employees, patients, healthcare professionals, and suppliers to limit exposure: we substantially restricted travel, supplied personal protective equipment to employees, limited access to our headquarters and asked most of our staff to work remotely. In addition, we added bandwidth and VPN capacity to our infrastructure to facilitate remote work arrangements. We will continue to monitor the impact of COVID-19 on our operations and report to our Board of Directors regularly on the progress of our response to the COVID-19 outbreak.

Financial Overview

Since our inception in 2008, we have devoted substantially all of our resources to synthesizing, acquiring, testing and developing our product candidates, including conducting preclinical studies and clinical trials and providing general and administrative support for these operations as well as securing intellectual property protection for our product candidates. As of April 2021, COSELA^TM is our only product approved for sale. We began generating revenue for the net product sales from COSELA in March of 2021. We recorded $0.6 million of net product sales from COSELA and $13.6 million of license revenue for the three months ended March 31, 2021, and $45.3 million of license revenue for the year ended December 31, 2020.  To date, we have financed our operations primarily through the sale of equity securities, our loan agreement with Hercules Capital, Inc., and licensing arrangements. Under our licensing arrangements, we are eligible to receive certain development and sales-based milestones. Our ability to earn these milestones and the timing of achieving these milestones is primarily dependent upon the outcome of the licensee’s activities and is uncertain at this time.

25

As of March 31, 2021, we had cash and cash equivalents of $279.0 million. Since inception we have incurred net losses. As of March 31, 2021 we had an accumulated deficit of $462.5 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs, our commercial launch preparations, and from general and administrative expenses associated with our operations. We expect to continue to incur significant expenses and increasing operating losses. We expect our research and development, commercial activities, and general and administrative expenses will continue to increase in connection with our ongoing and future activities as we:

License agreement with the University of Illinois

In November 2016, and as amended in March 2017, we entered into a license agreement with the Board of Trustees of the University of Illinois, (“the University”). Pursuant to the license agreement, as amended, the University licensed patent rights to us, with rights to sublicense, to make, have made, use, import, sell and offer for sale SERDs, including rintodestrant, covered by certain patent rights owned by the University. The rights licensed to us are exclusive, worldwide, non-transferable rights, for all fields of use. Under the terms of the agreement, as amended, we paid a one-time only, non-refundable upfront fee of $0.5 million, and are required to pay the University low single-digit royalties on all net sales of products and a share of any sublicensing revenues. We are also obligated to pay annual maintenance fees, which are fully creditable against any royalty payments made by us. In addition, we may also be required to pay the University milestone payments of up to an aggregate of $2.6 million related to the initiation and execution of clinical trials and the first commercial sale of a product and the first commercial sale of a product in another country. To date, we have made milestone payments totaling $0.6 million, of which $0 was incurred during the current quarter. We will also be responsible for any future patent prosecution costs that may arise.

Components of our Results of Operations

Revenue

On February 12, 2021, COSELA^TM was approved by the FDA and we began generating revenue for the product sales of COSELA in March 2021. Prior to the approval of COSELA, our revenues have been derived from our license agreements.

We entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) in August 2020 and granted them the rights to develop and commercialize trilaciclib in Greater China (mainland China, Hong Kong, Macau, and Taiwan) (the “Simcere Territory”). We received an upfront payment of $14.0 million (less applicable withholding taxes of $1.4 million) in September 2020. Revenue was recognized once the transfer of the related technology and know-how was completed in the fourth quarter of 2020. We have the potential to receive $156.0 million upon reaching development and commercial milestones, and receive tiered low double-digit royalties on annual net sales of trilaciclib in the Simcere Territory. During the three months ended March 31, 2021, two development milestones totaling $5.0 million were received and recognized as revenue.

26

We entered into an exclusive license agreement with EQRx, Inc. (“EQRx”) in July 2020 and granted them the rights to develop and commercialize lerociclib in the U.S, Europe, Japan and all other global markets, excluding the Asia-Pacific region (except Japan) (the “EQRx Territory”). We received an upfront payment of $20.0 million in August 2020. This was recognized as revenue in September 2020 when we transferred the license and related technology and know-how. We have the potential to receive $290.0 million upon reaching development and commercial milestones, and receive tiered royalties ranging from mid-single digits to mid-teens based on annual net sales of lerociclib in the EQRx Territory.

We entered into an exclusive license agreement with Genor Biopharma Co. Inc. (“Genor”) in June 2020 and granted them the rights to develop and commercialize lerociclib in the Asia-Pacific Region, excluding Japan (the “Genor Territory”). We received an upfront payment of $6.0 million in July 2020. This was recognized as revenue in September 2020 when we transferred the license and related technology and know-how. We have the potential to receive $40.0 million upon reaching development and commercial milestones, and receive tiered royalties ranging from high single to low double-digits based on annual net sales of lerociclib in the Genor Territory. During the three months ended March 31, 2021, one development milestone totaling $3.0 million was met and recognized as revenue, and payment was received in April 2021.

We entered into an exclusive license agreement with ARC Therapeutics, LLC (“ARC”) in May 2020.  The Company granted ARC an exclusive, worldwide, royalty-bearing license of its CDK2 inhibitor compounds in exchange for an upfront payment and equity in ARC with a total value of approximately $2.1 million, which resulted in the recognition of related party revenue. The Company is entitled to receive additional milestone payments and sales-based royalties, and has right of first negotiation to re-acquire these assets.

Operating expenses

We classify our operating expenses into three categories: cost of goods sold, research and development and selling, general and administrative. Personnel costs, including salaries, benefits, bonuses, and stock-based compensation expense, comprise a significant component of research and development and general and administrative expense categories. We allocate expenses associated with personnel costs based on the nature of work associated with these resources. In addition, costs to sell and market COSELA are included within selling, general and administrative expense categories.

Cost of goods sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of COSELA, including third-party manufacturing costs, packaging services, freight-in, third-party logistics costs associated with COSELA, and personnel costs. Cost of goods sold may also include period costs related to certain inventory manufacturing services and inventory adjustment charges.

Research and development expenses

The largest component of our total operating expenses since inception has been research and development activities, including the preclinical and clinical development of our product candidates.

Research and development costs are expensed as incurred. Our research and development expense primarily consists of:

The successful development of our product candidates is highly uncertain. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Accordingly, we expect research and development costs to increase significantly for the foreseeable future as programs progress. However, we do not believe that it is possible at this time to accurately project total program-specific expenses through commercialization. We are also unable to predict when, if ever, material net cash inflows will commence from our product candidates to offset these expenses. Our expenditures on current and future preclinical and clinical development

27

programs are subject to numerous uncertainties in timing and cost to completion. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including:

We track research and development expenses on a program-by-program basis only for clinical-stage product candidates. Preclinical research and development expenses and chemical manufacturing research and development expenses are not assigned or allocated to individual development programs. As of the first quarter of 2021, we had two clinical-stage product candidates, trilaciclib and rintodestrant.

Selling, general and administrative expenses

Selling, general and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including legal, audit and accounting services. Personnel costs consist of salaries, bonuses, benefits and stock-based compensation. Other general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees, commercialization costs, expenses associated with obtaining and maintaining patents and costs of our information systems. We anticipate that our general and administrative expenses will continue to increase in the future as we increase our headcount to support our continued research and development and commercialization of COSELA^TM.

We expect to continue to incur additional selling, general and administrative expenses in the future in connection with the commercialization of COSELA, as we support continued research and development activities, and as we support our operations in a public company environment, including expenses related to compliance with the rules and regulations of the SEC and Nasdaq, additional insurance expenses, and expenses related to investor relations activities.

Total other income (expense), net

Total other income (expense), net consists of interest income earned on cash and cash equivalents and interest expenses incurred under our loan and security agreement with Hercules.

Income taxes

To date, we have not been required to pay U.S. federal or state income taxes because we have not generated taxable income. Income tax expense recognized in 2021 relate to the foreign withholding taxes incurred as a result of the milestone payments received from the Simcere license agreement during the quarter.

Results of Operations

Comparison of the three months ended March 31, 2021 and March 31, 2020

Product sales, net

Product sales, net was $0.6 million and $0 for the three months ended March 31, 2021 and 2020, respectively. The revenue for three months ended March 31, 2021 related to the product sales of COSELA. We received FDA approval on February 12, 2021 and product was commercially available beginning March 2, 2021.

License Revenue

License revenue was $13.6 million and $0 for the three months ended March 31, 2021 and 2020, respectively. The revenue for the three months ended March 31, 2021 relates to revenue recognized from development milestones related to the Simcere and Genor license agreements, delivery of clinical drug supply and manufacturing services to EQRx and Genor, and amounts to be reimbursed by EQRx for the costs associated with the two primary lerociclib clinical trials.

Cost of goods sold

Cost of goods sold was $0.2 million and $0 for the three months ended March 31, 2021 and 2020, respectively, which relate to our third-party logistics costs for the sales of COSELA and personnel costs.

29

Research and development

Research and development expenses were $16.5 million for the three months ended March 31, 2021 compared to $20.4 million for the three months ended March 31, 2020. The decrease of $3.9 million, or -19%, was primarily due to a decrease of $3.4 million in costs for manufacturing of active pharmaceutical ingredients and drug product to support clinical trials, as well as a decrease of $0.7 million in external costs related to discovery, pre-clinical and other development costs. The decrease is partially offset by an increase of $0.2 million in spend for clinical trials. The following table summarizes our research and development expenses allocated to trilaciclib, rintodestrant, lerociclib and unallocated research and development expenses for the periods indicated:

Selling, general and administrative

Selling, general and administrative expenses were $23.0 million for the three months ended March 31, 2021 compared to $11.4 million for the three months ended March 31, 2020. The increase of $11.6 million, or 102%, was due to an increase of $4.1 million in personnel costs due to increased headcount, of which $1.5 million related to non-cash stock compensation expense, an increase of $6.6 million in commercialization activities, and an increase of $1.3 million in professional services, insurance and other administrative costs. The increase is partially offset by a decrease of $0.4 million in medical affairs costs related to trilaciclib.

Total other income (expense), net

Total other income (expense), net was $(0.8) million for the three months ended March 31, 2021 as compared to $0.8 million for the three months ended March 31, 2020. The decrease of $1.6 million, or -196%, was primarily due to the lower balance of money market funds due to cash used in operating activities and changes in interest rates during the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 and interest expense on our loan payable.

Income tax expense

Income tax expense was $0.1 million for the three months ended March 31, 2021 as compared to $0 for the three months ended March 31, 2020. The increase was related to the foreign withholding taxes incurred as a result of the development milestone payments received from the Simcere license agreement during the quarter.

Liquidity and Capital Resources

We have incurred cumulative losses and negative cash flows from operations since our inception in 2008. As of March 31, 2021, we had an accumulated deficit of $462.5 million. We do not expect to generate substantial revenue from the commercial sale of our products in the foreseeable future and anticipate that we will continue to incur losses.

As of March 31, 2021, we had cash and cash equivalents of $279.0 million. To date, we have funded our operations primarily through proceeds from our initial public offering, our follow-on stock offerings, our debt agreement with Hercules Capital, and proceeds from our license agreements. Under our licensing arrangements, we are eligible to receive certain development and sales-based milestones. Our ability to earn these milestones and the timing of achieving these milestones is primarily dependent upon the outcome of the licensee’s activities and are uncertain at this time.

30

Shelf registration statement

On June 15, 2018, we filed an automatically effective shelf registration statement with the Securities and Exchange Commission.  Each issuance under the shelf registration statement will require the filing of a prospectus supplement identifying the amount and terms of securities to be issued.  The registration statement does not limit the amount of securities that may be issued thereunder.  Our ability to issue securities is subject to market conditions and other factors. This registration statement will expire on June 15, 2021, three years after its date of effectiveness.

At-the-market offering

On June 15, 2018, we entered into a sales agreement for “at the market offerings” with Cowen and Company, LLC (“Cowen”), which allows us to issue and sell shares of common stock pursuant to a shelf registration statement for total gross sales proceeds of up to $125.0 million from time to time through Cowen, acting as our agent. Between June 18, 2018 and August 2, 2018, we sold 752,008 shares of common stock pursuant to this agreement resulting in $36.1 million in net proceeds, realizing $12.1 million in the second quarter of 2018 and the remaining $24.0 million by August 2, 2018.

Between January 14, 2021 and February 9, 2021, we sold 3,513,027 shares of common stock pursuant to this agreement resulting in $86.4 million in net proceeds. As of February 9, 2021, we have used the entirety of the remaining availability under the sales agreement with Cowen.

Loan and Security Agreement with Hercules

On May 29, 2020, we entered into a loan and security agreement with Hercules Capital, Inc. (“Hercules”) under which Hercules has agreed to lend us up to $100.0 million, to be made available in a series of tranches, subject to specified conditions. We borrowed $20.0 million at loan closing. The term of the loan is approximately 48 months, with an original maturity date of June 1, 2024. No principal payments are due during an interest-only period, commencing on the initial borrowing date and continuing through June 1, 2022. Per the terms of the loan agreement, upon reaching the performance milestone, the interest only period was to be extended through January 1, 2023 and we will now repay the principal balance and interest of the advances in equal monthly installments through the maturity date of June 1, 2025. On March 31, 2021, we entered into the First Amendment to Loan and Security Agreement with Hercules where we drew the remaining $10.0 million of the first tranche along with amending the interest rate and the financial covenants.

Genor License Agreement

On June 15, 2020, we entered into an exclusive license agreement with Genor Biopharma Co. Inc. (“Genor”) for the development and commercialization of lerociclib in the Asia-Pacific region, excluding Japan (the “Genor Territory”). Under the license agreement, we granted to Genor an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals for, and commercialize lerociclib, in the Genor Territory.

Under the license agreement, Genor agreed to pay us a non-refundable, upfront cash payment of $6.0 million with the potential to pay an additional $40.0 million upon reaching certain development and commercial milestones. In addition, Genor will pay us tiered royalties ranging from high single to low double-digits based on annual net sales of lerociclib in the Genor Territory. The upfront cash payment was received in July 2020. In September 2020, we transferred to Genor the related technology and know-how that is necessary to develop, seek regulatory approval for, and commercialize lerociclib in the Genor Territory. Genor will be responsible for the development of the product in the Genor Territory and will be responsible, at its sole cost, for obtaining supply of lerociclib to meet its development, regulatory approval, and commercialization obligations under the agreement. In the first quarter of 2021, we recognized revenue related to a development milestone of $3.0 million, for which cash was received in April 2021.

EQRx License Agreement

On July 22, 2020, we entered into an exclusive license agreement with EQRx, Inc. (“EQRx”) for the development and commercialization of lerociclib in the U.S., Europe, Japan and all other global markets, excluding the Asia-Pacific region (except Japan) (the “EQRx Territory”). Under the license agreement, we granted to EQRx an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals for, and commercialize lerociclib in the EQRx Territory.

Under the license agreement, EQRx agreed to pay us a non-refundable, upfront cash payment of $20.0 million with the potential to pay an additional $290.0 million upon reaching certain development and commercial milestones. In addition, EQRx will pay us tiered royalties ranging from mid-single digits to mid-teens based on annual net sales of lerociclib in the EQRx Territory. The upfront cash

31

payment was received in August 2020. In September 2020, we transferred to EQRx the related technology and know-how that is necessary to develop, seek regulatory approval for, and commercialize lerociclib in the EQRx Territory. EQRx will be responsible for the development of the product in the EQRx Territory. We will continue until completion, as the clinical trial sponsor, its two primary clinical trials at EQRx’s sole cost and expense. EQRx will reimburse us for all of its out-of-pocket costs incurred after the effective date of the license agreement in connection with these clinical trials. We will invoice EQRx within 30 days following the end of the quarter, and EQRx will pay within 30 days after its receipt of such invoice.

Simcere License Agreement

On August 3, 2020, we entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) for the development and commercialization of trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau, and Taiwan) (the “Simcere Territory”). Under the license agreement, we granted to Simcere an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals for, and commercialize trilaciclib in the Simcere Territory.

Under the license agreement, Simcere agreed to pay us a non-refundable, upfront cash payment of $14.0 million with the potential to pay an additional $156.0 million upon reaching certain development and commercial milestones. In addition, Simcere will pay us tiered low double-digit royalties on annual net sales of trilaciclib in the Simcere Territory. The upfront payment of $14.0 million (less applicable withholding taxes of $1.4 million) was received in September 2020. In return, we will furnish to Simcere the related technology and know-how that is necessary to develop, seek regulatory approval for, and commercialize trilaciclib in the Simcere Territory. Simcere will be responsible for all development and commercialization costs in its territory and may be able to participate in global clinical trials as agreed upon by the companies. In the first quarter of 2021, we received two development milestone payments totaling $5.0 million.

Cash flows

The following table summarizes our cash flows for the periods indicated:

Net cash used in operating activities

During the three months ended March 31, 2021, net cash used in operating activities was $26.9 million which consisted primarily of a net loss of $26.4 million and a decrease in net operating assets and liabilities of $7.0 million, partially offset, non-cash stock compensation expense of $5.9 million, $0.1 million of depreciation expense, $0.3 million in amortization of debt issuance costs, and $0.2 million of non-cash interest expense.

During the three months ended March 31, 2020, net cash used in operating activities was $27.0 million, which consisted primarily of a net loss of $31.0 million and a decrease in net operating assets and liabilities of $0.9 million, partially offset by non-cash stock compensation expense of $4.7 million and $0.2 million of depreciation expense.

Net cash used in operating activities decreased by $(0.1) million as compared to the three months ended March 31, 2020 primarily due to decrease in net loss from recognition of revenue offset by an increase in administrative costs as company prepared for commercialization.

Net cash used in investing activities

During the three months ended March 31, 2021 and the three months ended March 31, 2020, there was no cash provided or used in investing activities.

32

Net cash provided by financing activities

During the three months ended March 31, 2021, net cash provided by financing activities was $98.5 million, which consisted of $86.4 million in net proceeds from our ATM offering after deducting cash paid in the quarter for underwriting discounts and commissions and other expenses, $9.9 million in net proceeds from debt funding, and $2.2 million from proceeds from the exercise of stock options.

During the three months ended March 31, 2020, net cash provided by financing activities was $0.2 million from the exercise of stock options.

Operating capital requirements and plan of operations

We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of and seek regulatory approvals for our product candidates, and continue to commercialize COSELA^TM. We are subject to all of the risks inherent in the development of new products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. We expect to incur additional costs associated with operating as a public company and we anticipate that we will need substantial additional funding in connection with our continuing operations.

We believe that our existing cash and cash equivalents will be sufficient to fund our projected cash needs for at least the next 12 months.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

Until such time, if ever, as we can generate substantial revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. We do not have any committed external source of funds except for amounts included under our licensing arrangements and the loan agreement with Hercules. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay,

33

limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations, Commitments and Contingencies

The Company entered into a three-year co-promotion agreement in the United States and Puerto Rico with Boehringer Ingelheim Pharmaceuticals, Inc. (“BI”), in June 2020. Under the terms of the agreement, we will book revenue in the United States and Puerto Rico and retain development and commercialization rights to trilaciclib. We will lead marketing, market access and medical engagement initiatives; BI will lead sales force engagements. The agreement is limited to support for small cell lung cancer. There have been no material changes to our contractual obligations during the current period from those disclosed in our Annual Report on Form 10-K for year ended December 31, 2020.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of our financial statements requires us to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the dates of the balance sheet, and the reported amount of expenses incurred during the reporting period. In accordance with U.S. GAAP, we evaluate our estimates and judgments on an ongoing basis. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe that our accounting policies are critical to the process of making significant judgments and estimates in the preparation of our financial statements and understanding and evaluating our reported financial results. We discussed our accounting policies and significant assumptions used in our estimates in Note 2 of our audited financial statements included in our 2020 Form 10-K. There have been no material changes during the three months ended March 31, 2021 to our critical accounting policies, significant judgments and estimates disclosed in our 2020 Form 10-K.

Recent Accounting Pronouncements

See Note 2 to our unaudited condensed financial statements included in Item 1 of this Quarterly Report on Form 10-Q for recently issued accounting pronouncements, including respective adoption dates and the potential impact on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities, which are affected by changes in the general level of U.S. interest rates. We had cash and cash equivalents of $279.0 million as of March 31, 2021, which consists of deposits in banks, including checking accounts, money market accounts and certificates of deposit. Such interest-earning instruments carry a degree of interest rate risk; however, historical fluctuations in interest income have not been significant. Due to the short-term nature of our cash equivalents, a sudden change in interest rates would not be expected to have a material effect on our business, financial condition or results of operations.  

We also have exposure to market risk on our loan agreement with Hercules Capital, Inc. Our loan agreement accrues interest from its date of issue at a variable interest rate equal to the greater of either (i) (a) the prime rate as reported in The Wall Street Journal, plus (b) 6.20%, and (ii) 9.45%. As of March 31, 2021, $30.0 million was outstanding under the loan agreement with Hercules.

We are not currently exposed to significant market risk related to changes in foreign currency exchange rates; however, our operations may be subject to fluctuations in foreign currency exchange rates in the future.

Inflation generally affects us by increasing our cost of labor. We do not believe that inflation had a material effect on our business financial condition or results of operations during the three months ended March 31, 2021.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the 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 Securities and Exchange Commission’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, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2021, our principal executive officer and our principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Change in Internal Controls

During the three months ended March 31, 2021, in connection with the approval and commercial availability of COSELA, we designed and implemented new procedures and controls around our net product sales and inventory processes.

PART II—OTHER INFORMATION

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. In addition to the other information contained elsewhere in this report, you should carefully consider the risks and uncertainties described in our “Item 1A. Risk Factors” of our 2020 Form 10-K, which could materially affect our business, financial condition or future results before investing in our common stock. The information presented below updates, and should be read in conjunction with, the risk factors and information disclosed in our Form 10-K, as updated in our quarterly reports. Except as presented below, there have been no material changes from the risk factors described in our Form 10-K, as updated in our quarterly reports.

We depend almost entirely on the commercial success of COSELA. There is no assurance that our commercialization efforts in the U.S. with respect to COSELA will be successful or that we will be able to generate revenues at the levels or within the timing we expect or at the levels or within the timing necessary to support our goals.

To date, we have not generated significant revenues from the sale of COSELA^TM. COSELA was approved by the FDA on February 12, 2021 and became commercially available on March 2, 2021. There is no assurance that the launch of COSELA will be successful. We may encounter delays or hurdles related to our launch that affect the commercial success of COSELA.

Our business currently depends heavily on our ability to successfully commercialize COSELA in the U.S. to treat patients with ES-SCLC. We may never be able to successfully commercialize COSELA or meet our expectations with respect to revenues. We have never marketed, sold or distributed for commercial use any pharmaceutical product. There is no guarantee that the infrastructure, systems, processes, policies, personnel, relationships and materials we have built in anticipation of the launch and commercialization of COSELA in the U.S. will be sufficient for us to achieve success at the levels we expect. Additionally, healthcare providers may not accept a new treatment paradigm for patients with ES-SCLC. We may also encounter challenges related to reimbursement of COSELA, even if we have positive early indications from payors, including potential limitations in the scope, breadth, availability, or amount of reimbursement covering COSLEA. Similarly, healthcare settings or patients may determine that the financial burdens of treatment are not acceptable. Our results may also be negatively impacted if we have not adequately sized our field teams or our physician segmentation and targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes. Any of these issues could impair our ability to successfully commercialize COSELA or to generate substantial revenues or profits or to meet our expectations with respect to the amount or timing of revenue or profits. Any issues or hurdles related to our commercialization efforts may materially adversely affect our business, results of operations, financial condition and prospects. There is no guarantee that we will be successful in our launch or commercialization efforts with respect to COSELA.
