This discussion and other parts of this Quarterly Report on Form 10-Q 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 this Quarterly Report 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 clinical-stage precision medicines company transforming the drug discovery process by combining leading-edge computational and experimental technologies with the goal of bringing life-changing therapies to patients. As we believe we are among the first of a new breed of biotech created at the intersection of disparate technologies, we aim to push the boundaries of what's possible in drug discovery. Our Dynamo™ platform integrates an array of leading-edge computational and experimental approaches designed to drug protein targets that have previously been intractable. Our initial focus is on enhancing small molecule therapeutic discovery in targeted oncology and genetic disease indications.

We are advancing a pipeline of medicines to address targets in precision oncology, including our lead product candidates, RLY-4008, RLY-2608 and RLY-1971.

RLY-4008. In the third quarter of 2020, we initiated a first-in-human clinical trial for RLY-4008, a potent, selective and oral small molecule inhibitor of fibroblast growth factor receptor 2, or FGFR2, for patients with advanced or metastatic FGFR2-altered solid tumors. In October 2021, we announced initial clinical data from this trial, which suggested robust inhibition of FGFR2 in the first 49 subjects that was not observed to be limited by off-target toxicities, including hyperphosphatemia and diarrhea, as of the data cut-off date of September 9, 2021. In December 2021, we initiated expansion cohorts at a continuous 70 mg once-daily, or QD, dose, and in January 2022, the U.S. Food and Drug Administration, or FDA, granted orphan drug designation to RLY-4008 for the treatment of cholangiocarcinoma, or CCA. In the first half of 2022, we conducted an end-of-phase 1 meeting with the FDA to discuss next steps for the clinical development of RLY-4008. Based on discussions with the FDA, we have decided to move forward with a single arm trial design for pan-FGFR, or FGFRi, treatment-naïve FGFR2-fusion CCA to potentially support accelerated approval. In June 2022, we announced the anticipated registrational path for RLY-4008 in CCA and the interim clinical data with a data cut-off date of April 19, 2022 that was shared with the FDA to support such path. The interim clinical data included a safety database of 115 patients, with 58 patients treated with the QD dosing schedule, and 13 of these patients were FGFRi treatment-naïve FGFR2-fusion CCA patients treated with the QD dosing schedule ranging from 20 mg up to 70 mg. The interim clinical data from the QD dosing schedule shared with the FDA demonstrated confirmed partial responses in eight out of thirteen, or 62%, FGFRi-naïve FGFR2-fusion CCA patients, including all four of the patients treated at the registrational trial dose of 70 mg QD. The safety analysis of this interim clinical data was consistent with our analysis of the initial clinical data as of September 9, 2021.

RLY-2608. In December 2021, we dosed the first patient in a first-in-human clinical trial for RLY-2608, the first known allosteric, pan-mutant (H1047X, E542X and E545X) and isoform-selective phosphoinostide 3 kinase alpha, or PI3K?, inhibitor in clinical development. In April 2022, we initiated the second arm of the dose escalation part of this trial, evaluating RLY-2608 in combination with fulvestrant for patients with HR+, HER2-, PI3K?-mutated, locally advanced or metastatic breast cancer. RLY-2608 is the lead program of multiple efforts in our PI3K? franchise to discover and develop mutant selective inhibitors of PI3K?. In the fourth quarter of 2021, we announced preclinical data for RLY-2608, in which we observed that RLY-2608 preferentially bound to mutant PI3K? at a novel allosteric site discovered by the Dynamo platform. The data also suggest that projected clinically relevant doses of RLY-2608 achieved tumor regression in PIK3CA mutant in vivo xenograft mouse models representing H1047R and E545K mutations with significantly reduced impact on glucose metabolism compared to non-mutant selective active site inhibitors. The data further suggest that in preclinical models, RLY-2608 combined with standard of care therapies facilitated regressions in ER+/HER2- breast cancer.

RLY-1971. We initiated a Phase 1 clinical trial for RLY-1971, our inhibitor of Src homology region 2 domain-containing phosphatase-2, or SHP2, in patients with advanced solid tumors in the first quarter of 2020. In December 2020, we entered into a global collaboration and license agreement, or the License Agreement, with Genentech, Inc., a member of the Roche Group, or Genentech, for the development and commercialization of RLY-1971. In July 2021, Genentech initiated the cohort of RLY-1971 in combination with GDC-6036, its KRAS G12C inhibitor, in a Phase 1b trial.

While our initial focus is on precision oncology, we believe our Dynamo platform may also be broadly applied to other areas of precision medicine, such as genetic disease indications. In addition to the three product candidates described above, we have over five discovery stage programs across both precision oncology and genetic disease. We announced three of these discovery stage programs in June 2022 as part of our HR+/HER2- breast cancer franchise, including a selective cyclin dependent kinase 2, or CDK2, inhibitor, a rationally designed estrogen receptor alpha, or ER?, degrader and a selective and chemically distinct pan-mutant PI3K? inhibitor, RLY-5836. We are focused on using the novel insights derived from our approach to transform the lives of patients suffering from debilitating and life-threatening diseases through the discovery, development and commercialization of our therapies.



                                       11

--------------------------------------------------------------------------------

We were incorporated in May 2015. We have devoted substantially all of our resources to developing our lead product candidates, developing our innovative computational and experimental approaches on protein motion, building our intellectual property portfolio, business planning, raising capital and providing general and administrative support for these operations. To date, we have principally financed our operations through private placements of preferred stock, convertible debt and proceeds from public offerings of our common stock. Additionally, in 2021, we received an aggregate of $95.0 million in connection with the License Agreement with Genentech.

In October 2021, we completed a public offering, or the October 2021 Offering, of 15,188,679 shares of common stock, including the exercise in full of the underwriters' option to purchase an additional 1,981,132 shares, at an offering price of $26.50 per share, for net proceeds of $382.2 million, after deducting underwriting discounts and commissions and other offering expenses. In July 2020, we closed our initial public offering, or IPO, and issued 23,000,000 shares of our common stock at a price of $20.00 per share for net proceeds of $425.3 million, after deducting underwriting discounts and commissions and offering expenses. Prior to our IPO, we had received gross proceeds of approximately $520.0 million from sales of our preferred stock and our issuance of convertible debt.

In August 2021, we entered into the Discovery and Collaboration Agreement, or Collaboration Agreement, with EQRx, Inc., or EQRx, to discover, develop, and commercialize novel medicines against validated oncology targets. Under the terms of the agreement, we will be responsible for the discovery phase through to filing of the application for an Investigational New Drug, or IND, while EQRx will be responsible for clinical development, regulatory and commercialization efforts of the product candidates developed pursuant to the collaboration. Subject to certain opt-out rights, we and EQRx will equally share in the discovery, development and commercialization costs and the net profits from sales of any collaboration medicines, if approved. We retain the right to develop any collaboration medicines in combination with our wholly-owned pipeline.

On April 15, 2021, we entered into an Agreement and Plan of Merger, or the Merger Agreement, and on April 22, 2021, we acquired ZebiAI Therapeutics, Inc., or ZebiAI. Pursuant to the Merger Agreement, we were required to pay ZebiAI's former stockholders, option holders and warrant holders, or the ZebiAI Holders, upfront consideration in an aggregate amount of approximately $85.0 million, excluding customary purchase price adjustments, composed of approximately $20.0 million payable in cash and approximately $65.0 million payable in shares of our common stock. In addition, (i) the ZebiAI Holders will be eligible to receive up to an additional $85.0 million in milestone payments upon the achievement of certain platform or program-related milestones, payable in our common stock and (ii) we will pay to the ZebiAI Holders 10% of the payments we receive within three years of the closing date of the Merger Agreement from partnering, collaboration or other agreements related to ZebiAI's platform up to an aggregate maximum amount of $100.0 million, payable in cash.

In December 2020, we entered into the License Agreement with Genentech for the development and commercialization of RLY-1971. Under the terms of the License Agreement, we received $75.0 million in an upfront payment and $20.0 million in milestone payments from Genentech in 2021. We are eligible to receive an additional $5.0 million in near-term payments; and, if we do not opt into a U.S. profit/cost share, up to $695.0 million in additional development, commercialization and sales-based milestones for RLY-1971; and tiered royalties on annual global net sales (on a country-by-country basis), anticipated to be in the low-to-mid-teens, subject to reductions in certain circumstances. Additionally, we are eligible to receive additional royalties in the event of regulatory approval of RLY-1971 and Genentech's compound, GDC-6036, that directly binds to and inhibits KRAS G12C, in combination. We have the right to opt-in to a 50/50 U.S. profit/cost share and if we do opt into the U.S. profit/cost share, we are eligible to receive up to $410.0 million in additional commercialization and sales-based milestones for RLY-1971 outside of the U.S. and tiered royalties on annual net sales outside of the U.S. (on a country-by-country basis), anticipated to be in the low-to-mid-teens, subject to reduction in certain circumstances. We also retain the right to develop RLY-1971 in combination with our FGFR2 and PI3K? programs.

The ongoing COVID-19 pandemic has presented a substantial public health and economic challenge around the world and continues to affect our employees, patients, communities and business operations. The extent to which the COVID-19 pandemic may continue to affect our operations or those of our third-party partners, including our preclinical studies or clinical trial operations, will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the severity and duration of additional variant outbreaks, vaccination rates where we or our third party partners conduct operations, and the actions to contain COVID-19 or treat its impact, among others. The continued spread of COVID-19 globally could adversely impact our preclinical or clinical trial operations in the United States, including our ability to obtain slots for IND-enabling studies, recruit and retain patients, principal investigators and site staff in our clinical trials, obtain sufficient clinical trial supply of our product candidates due to supply chain disruptions or interruptions in global shipping, as well as activate new clinical trial sites. To date, we have been able to continue to enroll our patients in first-in-human clinical trials for RLY-1971, RLY-4008, and RLY-2608, and we currently do not anticipate any interruptions in clinical enrollment or any material adverse impact on our financial condition or results of operations due to the ongoing COVID-19 pandemic. However, we are continuing to assess the potential impact of the ongoing COVID-19 pandemic on our current and future business and operations, including our expenses and clinical trials, as well as on our industry and the healthcare system. See "-The ongoing COVID-19 pandemic has impacted our business and any future pandemic, epidemic, or outbreak of an infectious disease could similarly affect our business and our financial results and could cause further disruption to the development of our product candidates" for a more detailed discussion of the risks related to the ongoing COVID-19 pandemic.

Additionally, inflation generally affects us by increasing our employee-related costs and clinical trial expenses, as well as other operating expenses. Our financial condition and results of operations may also be impacted by other factors we may not be able to control, such as global supply chain disruptions, uncertain global economic conditions, global trade disputes or political instability as further discussed in the section "Risk Factors" in this Quarterly Report. We do not believe that such factors had a material adverse impact on our results of operations during the three and six months ended June 30, 2022.



                                       12

--------------------------------------------------------------------------------

Since our inception, we have incurred significant operating losses on an aggregate basis. Our ability to generate product revenue sufficient to achieve profitability will depend on the successful development and eventual commercialization of one or more of our current or future product candidates. Our net losses were $138.8 million and $235.6 million for the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, we had an accumulated deficit of $906.9 million. These losses have resulted primarily from costs incurred in connection with research and development activities, licensing and patent investment and general and administrative costs associated with our operations. We expect to continue to incur significant expenses, including the costs of operating as a public company, and generate increasing operating losses for at least the next several years.

We anticipate that our expenses will increase substantially if and as we:

conduct our current and future clinical trials of RLY-4008 and RLY-2608;

conduct additional preclinical research and development of RLY-5836, our PI3K? mutant selective inhibitor, CDK2 inhibitor and ER? degrader programs and other early-stage programs;

initiate and continue research and preclinical and clinical development of our other product candidates;

seek to identify additional product candidates;

pursue marketing approvals for any of our product candidates that successfully complete clinical trials, if any;

establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval;

require the manufacture of larger quantities of our product candidates for clinical development and potentially commercialization;

obtain, maintain, expand and protect our intellectual property portfolio;

acquire or in-license other drugs and technologies;

hire and retain additional clinical, regulatory, quality and scientific personnel;

build out new facilities or expand existing facilities to support our ongoing development activity; and

add operational, financial and management information systems and personnel, including personnel to support our drug development, any future commercialization efforts and our operations as a public company.

In addition, if we obtain marketing approval for any of our lead product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution.

As a result, we will need additional financing to support our continuing operations. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity or debt financings or other sources, which may include collaborations with third parties. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed, on favorable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development or commercialization of one or more of our product candidates.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate revenue from product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and may be forced to reduce or terminate our operations.

We believe our cash, cash equivalents and investments of $838.0 million as of June 30, 2022, will enable us to fund our operating expenses and capital expenditure requirements into at least 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. We will need to raise additional capital in the future to continue developing the drugs in our pipeline and to commercialize any approved drug. We may seek to obtain additional financing in the future through the issuance of our common stock, through other equity or debt financings or through collaborations or partnerships with other companies. We may not be able to raise additional capital on terms acceptable to us, or at all, and any failure to raise capital as and when needed could compromise our ability to execute on our business plan.

--------------------------------------------------------------------------------

Components of our Results of Operations

Revenue

To date, our revenue consists primarily of amounts related to the License Agreement with Genentech. We recognize our revenue as the performance obligations are satisfied under the agreement.

Operating Expenses

Research and Development Expenses

Research and development expenses include:

salaries, benefits and other employee related costs, including stock-based compensation expense, for personnel engaged in research and development functions;

costs of outside consultants, including their fees, stock-based compensation and related travel expenses;

expenses incurred under agreements with contract research organizations, or CROs, contract manufacturing organizations, or CMOs, and other vendors that conduct our clinical trials and preclinical activities;

costs of acquiring, developing and manufacturing clinical trial materials and lab supplies;

costs related to compliance with regulatory requirements; and

facility costs, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies. We do not allocate certain internal costs, facilities, or overhead costs to specific development programs.

We expense research and development costs as the services are performed or the goods are received. We recognize costs for certain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or other information provided to us by our vendors and our clinical investigative sites. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid expenses or accrued research and development expenses.

Our most advanced development programs, RLY-1971, RLY-4008 and RLY-2608, are in first-in-human clinical trials. We have over five discovery stage programs across both precision oncology and genetic disease indications. Costs incurred for these programs include costs incurred to support our discovery research and translational science efforts up to the initiation of first-in-human clinical development. Platform research and other research and development activities include costs that are not specifically allocated to active product candidates, including facilities costs, depreciation expense and other costs. Employee related expenses includes salary, wages, stock-based compensation and other costs related to our personnel, which are not allocated to specific programs or activities.

We cannot determine with certainty the duration and costs of future clinical trials and future development costs, if, when or to what extent we will generate revenue from the commercialization and sale of any of our product candidates for which we obtain marketing approval or our other research and development costs. We may never succeed in obtaining marketing approval for any of our product candidates.

The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including:

the scope, rate of progress, expense and results of our preclinical development activities, any future clinical trials of RLY-4008, RLY-2608 or other product candidates and other research and development activities that we may conduct;

uncertainties in clinical trial design and patient enrollment or drop out or discontinuation rates;

establishing an appropriate safety and efficacy profile with IND-enabling studies;

the initiation and completion of future clinical trial results;

the timing, receipt and terms of any approvals from applicable regulatory authorities including the FDA and non-U.S. regulators;

significant and changing government regulation and regulatory guidance;



                                       14

--------------------------------------------------------------------------------

potential additional studies requested by regulatory agencies;

establishing clinical and commercial manufacturing capabilities or making arrangements with third-party manufacturers in order to ensure that we or our third-party manufacturers are able to make product successfully;

the impact of any business interruptions to our operations, including the timing and enrollment of patients in our planned clinical trials, or to those of our manufacturers, suppliers or other vendors resulting from the ongoing COVID-19 pandemic or a similar public health crisis or the changing political conditions such as the current conflict between Russia and Ukraine and related global economic sanctions;

the expense of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; and

maintaining a continued acceptable safety profile of our product candidates following approval, if any, of our product candidates.

Research and development activities are central to our business model. 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. We expect that our research and development expenses will continue to increase for the foreseeable future as we continue to conduct clinical trials of RLY-4008 and RLY-2608, as well as identify and develop additional product candidates.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant trial delays due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time on the completion of clinical development.

In-Process Research and Development Expenses

In-process research and development expenses consist of the cost of acquiring in-process research and development assets that have no alternative future use, specifically in connection with our acquisition of ZebiAI. We do not expect to record incremental expenses in connection therewith in future periods.

Loss on Initial Consolidation of Variable Interest Entity

Loss on initial consolidation of variable interest entity consists of the difference between total consideration transferred and the fair value of net assets acquired and liabilities assumed in connection with our acquisition of ZebiAI. We do not expect to record incremental losses in connection therewith in future periods.

Change in Fair Value of Contingent Consideration Liability

Change in fair value of contingent consideration liability consists of fluctuations in the estimated fair value of contingent milestone payments under the Merger Agreement with ZebiAI. In future periods, we expect the fair value of such contingent milestone payments to increase or decrease based on, among other things, our estimates of the probability of achieving and timing of the contingent milestone payments, as well as changes in market interest rates and the time value of money.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, finance, corporate and business development and administrative functions. General and administrative expenses also include legal fees relating to patent and corporate matters; professional fees for accounting, auditing, tax and consulting services; other expenses associated with operating as a public company, including compliance with exchange listing and Securities and Exchange Commission, or SEC, requirements, director and officer insurance costs, and investor and public relations costs; travel expenses; and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.

We expect that our general and administrative expenses will increase in the future as we increase our general and administrative personnel headcount to support personnel in research and development and to support our operations generally as we increase our research and development activities and activities related to the potential commercialization of our product candidates.

Other Income, Net

Other income, net primarily consists of interest income related to interest earned on our cash, cash equivalents and investments.



                                       15

--------------------------------------------------------------------------------

Income Taxes

Since our inception in 2015, we have not recorded any U.S. federal or state income tax benefits for the net losses we have incurred in any year or for our earned research and development tax credits due to our uncertainty of realizing a benefit from those items.

Revenue

We recognized revenue of approximately $0.4 million and $0.8 million for the three months ended June 30, 2022 and 2021, respectively. The decrease of $0.4 million was primarily due to the decrease in research and development services provided under the License Agreement with Genentech, as we are nearing completion of the Phase 1a clinical trial of RLY-1971.

Research and Development Expenses

The following summarizes our research and development expenses for the three months ended June 30, 2022 and 2021:



                                                   Three Months Ended
                                                        June 30,              Change

Total research and development expenses $ 60,511 $ 45,147 $ 15,364

Research and development expenses were $60.5 million for the three months ended June 30, 2022 compared to $45.1 million for the three months ended June 30, 2021. The increase of $15.4 million was primarily due to $3.4 million of additional employee related costs due to increased headcount, $8.0 million related to additional clinical trial expenses in connection with the ongoing enrollment of our clinical trial for RLY-4008 and the initiation of our clinical trial for RLY-2608 in the fourth quarter of 2021, and $3.4 million related to preclinical programs.

In-Process Research and Development Expenses

In-process research and development expenses of $123.0 million were recognized for the three months ended June 30, 2021 in connection with the in-process research and development asset pursuant to the asset acquisition of ZebiAI in the second quarter of 2021. No such expenses were incurred during the three months ended June 30, 2022.

Loss on Initial Consolidation of Variable Interest Entity

Loss on initial consolidation of variable interest entity of $11.9 million was recognized for the three months ended June 30, 2021 in connection with the acquisition of ZebiAI in the second quarter of 2021. No such expenses were incurred during the three months ended June 30, 2022.



                                       16

--------------------------------------------------------------------------------

Change in Fair Value of Contingent Consideration Liability

The fair value of our contingent consideration liability for milestones under the Merger Agreement with ZebiAI increased by $0.2 million during the three months ended June 30, 2022. The increase was primarily attributable to changes in the assumptions underlying the fair value measurement between March 31, 2022 and June 30, 2022. Because the Merger Agreement with ZebiAI was only executed during the three months ended June 30, 2021, there were no similar amounts in the prior period. In future periods, we expect the fair value of contingent consideration to increase or decrease based on, among other things, our estimates of the probability of achieving and the timing of the contingent milestone payments, as well as changes in market interest rates and the time value of money.

General and Administrative Expenses

General and administrative expenses were $17.5 million for the three months ended June 30, 2022 compared to $14.4 million for the three months ended June 30, 2021. The increase of $3.0 million was primarily due to $3.0 million of additional employee related costs due to increased headcount, including an increase in stock-based compensation expense of $1.0 million.

Other Income, Net

Other income, net, was $1.0 million for the three months ended June 30, 2022 compared to $0.2 million for the three months ended June 30, 2021. The increase of $0.8 million was primarily a result of changes in interest rates.

Revenue

We recognized revenue of approximately $0.8 million and $1.8 million for the six months ended June 30, 2022 and 2021, respectively. The decrease of $1.0 million was primarily related to revenue recognized upon the transfer of active pharmaceutical ingredient during the six months ended June 30, 2021, for which no revenue was recognized during the six months ended June 30, 2022.

Research and Development Expenses

The following summarizes our research and development expenses for the six months ended June 30, 2022 and 2021:



                                                    Six Months Ended

Total research and development expenses $ 112,178 $ 75,769 $ 36,409

Research and development expenses were $112.2 million for the six months ended June 30, 2022 compared to $75.8 million for the six months ended June 30, 2021. The increase of $36.4 million was primarily due to $12.8 million of additional employee related costs due to increased headcount, including an increase in stock-based compensation of $1.0 million, $14.0 million related to additional clinical trial expenses in connection with the ongoing enrollment of our clinical trial for RLY-4008 and the initiation of our clinical trial for RLY-2608 in the fourth quarter of 2021, and $8.0 million related to preclinical programs.

In-Process Research and Development Expenses

In-process research and development expenses of $123.0 million were recognized for the six months ended June 30, 2021 in connection with the in-process research and development asset pursuant to the asset acquisition of ZebiAI in the second quarter of 2021. No such expenses were incurred during the six months ended June 30, 2022.

Loss on Initial Consolidation of Variable Interest Entity

Loss on initial consolidation of variable interest entity of $11.9 million was recognized for the six months ended June 30, 2021 in connection with the acquisition of ZebiAI in the second quarter of 2021. No such expenses were incurred during the six months ended June 30, 2022.

Change in Fair Value of Contingent Consideration Liability

The fair value of our contingent consideration liability for milestones under the Merger Agreement with ZebiAI decreased by $4.4 million during the six months ended June 30, 2022. The decrease was primarily attributable to changes in the assumptions underlying the fair value measurement between December 31, 2021 and June 30, 2022. Because the Merger Agreement with ZebiAI was only executed during the six months ended June 30, 2021, there were no similar amounts in the prior period. In future periods, we expect the fair value of contingent consideration to increase or decrease based on, among other things, our estimates of the probability of achieving and the timing of the contingent milestone payments, as well as changes in market interest rates and the time value of money.

General and Administrative Expenses

General and administrative expenses were $33.5 million for the six months ended June 30, 2022 compared to $27.2 million for the six months ended June 30, 2021. The increase of $6.4 million was primarily due to $6.1 million of additional employee related costs due to increased headcount, including an increase in stock-based compensation expense of $1.8 million.

Other Income, Net

Other income, net, was $1.7 million for the six months ended June 30, 2022 compared to $0.4 million for the six months ended June 30, 2021. The increase of $1.3 million was primarily a result of changes in interest rates.

Liquidity and Capital Resources

Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses. We have not yet commercialized any products and we do not expect to generate revenue from sales of any product candidates for several years, if ever. To date, we have principally financed our operations through private placements of preferred stock, convertible debt and proceeds from public offerings of our common stock. In July 2020, we closed our IPO and issued 23,000,000 shares of common stock for net proceeds of $425.3 million. Prior to our IPO, we received gross proceeds of $520.0 million from sales of our preferred stock and our issuance of convertible debt. We received an upfront payment of $75.0 million from Genentech pursuant to the License Agreement with Genentech in January 2021 and $20.0 million in milestone payments in 2021. As of June 30, 2022, we had cash, cash equivalents and investments of $838.0 million.

In August 2021, we filed a universal shelf registration statement on Form S-3ASR with the SEC, or the 2021 Shelf, to register for sale an amount of our common stock, preferred stock, debt securities, warrants and/or units in one or more offerings, which became effective upon filing with the SEC (File No. 333-258768).

In August 2021, we entered into a sales agreement, or Sales Agreement, with Cowen and Company, LLC, or Cowen, pursuant to which we may offer and sell shares of our common stock having aggregate gross proceeds of up to $300.0 million from time to time in "at-the-market" offerings through Cowen, as our sales agent. We agreed to pay Cowen a commission of up to 3.0% of the gross proceeds of any shares sold by Cowen under the Sales Agreement. There have been no shares of our common stock sold under the Sales Agreement as of June 30, 2022.

In October 2021, we completed the October 2021 Offering of 15,188,679 shares of common stock, including the exercise in full of the underwriters' option to purchase an additional 1,981,132 shares, at an offering price of $26.50 per share. We received net proceeds of $382.2 million, after deducting underwriting discounts and commissions and other offering expenses.

Operating Activities

During the six months ended June 30, 2022, we used $106.3 million of cash on operating activities, primarily resulting from our net loss of $138.8 million, offset by non-cash charges of $27.4 million and cash provided by changes in our operating assets and liabilities of $5.1 million.

During the six months ended June 30, 2021, operating activities provided $18.5 million of cash, primarily resulting from changes in our operating assets and liabilities of $90.8 million, offset by our net loss excluding non-cash charges of $72.3 million.

Investing Activities

During the six months ended June 30, 2022, investing activities used $69.0 million of cash, consisting of $64.3 million of net purchases of investments and $4.7 million for the acquisition of property and equipment.

During the six months ended June 30, 2021, investing activities used $207.6 million of cash, consisting of $181.6 million of net purchases of investments, $25.1 million in cash paid for the acquisition of ZebiAI, and $0.9 million for the acquisition of property and equipment.

Financing Activities

During the six months ended June 30, 2022, net cash provided by financing activities was $2.9 million, consisting of proceeds from the exercise of stock options and purchases under our Employee Stock Purchase Plan, or ESPP.

During the six months ended June 30, 2021, net cash provided by financing activities was $3.2 million, consisting of proceeds from the exercise of stock options.

Funding Requirements

We expect our expenses to increase substantially in connection with our ongoing clinical development activities related to the potential clinical development activities of RLY-4008 and RLY-2608 and the ongoing preclinical development activities of our other programs. In addition, we continue to incur additional costs associated with operating as a public company. We expect that our expenses will increase substantially as discussed in more detail in "¾ Overview" above.

As of June 30, 2022, we had cash, cash equivalents and investments of $838.0 million. We believe that our existing cash, cash equivalents and investments will enable us to fund our operating expenses and capital expenditure requirements into at least 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with the development of RLY-4008, RLY-2608 and our other product candidates and programs, and because the extent to which we may enter into collaborations with third parties for the development of our product candidates is unknown, we are unable to estimate the timing and amounts of increased capital outlays and operating expenses associated with completing the research and development of our product candidates. Our future capital requirements will depend on many factors, including:

the impact of any business interruptions to our operations, including the timing and enrollment of patients in our planned clinical trials, or to those of our manufacturers, suppliers or other vendors, resulting from the ongoing COVID-19 pandemic or similar public health crisis or the changing political conditions such as the current conflict between Russia and Ukraine and related global economic sanctions;

the scope, progress, results and costs of our current and future clinical trials of RLY-4008 and RLY-2608 and additional preclinical research of our other programs;



                                       19

--------------------------------------------------------------------------------

the scope, progress, results and costs of drug discovery, preclinical research and clinical trials for our other product candidates;

the number of future product candidates that we pursue and their development requirements;

the costs, timing and outcome of regulatory review of our product candidates;

our ability to establish and maintain collaborations on favorable terms, if at all;

the success of any existing or future collaborations that we may enter into with third parties;

the extent to which we acquire or invest in businesses, products and technologies, including entering into licensing or collaboration arrangements for product candidates, such as our collaboration with Genentech;

the achievement of milestones or occurrence of other developments that trigger payments under any existing or future collaboration agreements, if any;

the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under any existing or future collaboration agreements, if any;

the costs and timing of future commercialization activities, including drug sales, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval, to the extent that such sales, marketing, manufacturing and distribution are not the responsibility of any collaborator that we may have at such time;

the amount of revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive marketing approval;

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

our headcount growth and associated costs as we expand our business operations and our research and development activities; and

the costs of operating as a public company.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval for any product candidates or generate revenue from the sale of any product candidate for which we may obtain marketing approval. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of drugs that we do not expect to be commercially available for many years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives.

Adequate additional funds may not be available to us on acceptable terms, or at all. We do not currently have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest may be diluted, and the terms of these securities may include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as a common stockholder. Additional debt or preferred equity financing, if available, may involve agreements that include restrictive covenants that may limit our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends, which could adversely impact our ability to conduct our business, and may require the issuance of warrants, which could potentially dilute your ownership interest.

If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technology, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or collaborations, strategic alliances or licensing arrangements with third parties when needed, we may be required to delay, limit, reduce and/or terminate our product development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Critical Accounting Policies and Use of Estimates

Our management's discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of our condensed consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

For a discussion of our critical accounting estimates, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 24, 2022, the notes to our audited financial statements appearing in our Annual Report on Form 10-K and the notes to the financial statements appearing elsewhere in this Quarterly Report on Form 10-Q. There have been no material changes to these critical accounting policies and estimates through June 30, 2022 from those discussed in our Annual Report on Form 10-K for the year ended December 31, 2021.

Recently Issued and Adopted Accounting Pronouncements

A description of recently issued accounting pronouncements that we have adopted is disclosed in Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. None of these pronouncements had a material impact on our financial position or results of operations.
