Overview
We are a commercial-stage dermatological cancer company focused on providing physicians and their patients with personalized, clinically actionable genomic information to make more accurate treatment decisions. We believe that the traditional approach to developing a treatment plan for certain cancers using clinical and pathology factors alone can be improved by incorporating personalized genomic information. Our non-invasive genomic products utilize proprietary algorithms to provide an assessment of a patient’s specific risk of metastasis or recurrence of their cancer, allowing physicians to identify patients who are likely to benefit from an escalation of care as well as those who may avoid unnecessary medical and surgical interventions. Our lead product, DecisionDx-Melanoma, is a proprietary multi-gene expression profile, or GEP, test that predicts the risk of metastasis or recurrence for patients diagnosed with invasive cutaneous melanoma, a deadly skin cancer. We also market DecisionDx-UM, which is also a proprietary GEP test that predicts the risk of metastasis for patients with uveal melanoma, a rare eye cancer. Based on the substantial clinical evidence that we have developed, we have received Medicare coverage for both of our products, which represents approximately 50% of our addressable patient population. We also have two proprietary products in late-stage development that address high-risk cutaneous squamous cell carcinoma, or high-risk SCC, and suspicious pigmented lesions, which are indications with high clinical need in dermatological cancer. Clinical validation studies have been completed for both of these late-stage pipeline products and we plan to make these products clinically available in the second half of 2020.
Skin cancer is the most commonly diagnosed cancer in the United States. There are more than 5.5 million new cases of skin cancer diagnosed annually, compared with 1.6 million new cases for all other cancers combined. DecisionDx-Melanoma targets an estimated 130,000 patients diagnosed with invasive cutaneous melanoma each year, which we believe is underreported. In addition, our two late-stage proprietary products in development target approximately 200,000 patients diagnosed with high-risk SCC and approximately 300,000 patients with suspicious pigmented lesions without a definitive diagnosis of skin cancer. We estimate that the total addressable U.S. market for these three products is approximately $2.0 billion.
Healthcare providers, predominately dermatologists and surgeons who treat melanoma patients, make nearly all treatment decisions for patients diagnosed with skin cancers based upon their expected risk of metastasis or recurrence. Historically these treatment decisions have been based solely on clinical and pathology factors, such as tumor depth or width, ulceration status, nerve invasion and evidence of metastasis to the sentinel lymph node, or SLN. Physicians use these factors to group, or stage, patients into stage-related populations. The average risk of metastasis within a population then guides treatment decisions for all patients within a respective population. However, an individual patient’s risk of metastasis can be significantly different from these stage-related population averages, thereby resulting in some patients receiving unnecessary medical and surgical interventions and some patients being undertreated. This treatment paradigm has led to suboptimal patient care and unnecessary costs to the healthcare system.
We believe that incorporating the genomics of each individual patient’s tumor biology to inform their specific risk of metastasis can aid the decision-making process for their treatment plan, help optimize patient outcomes and reduce healthcare costs. The genomics of cutaneous melanoma and other skin cancers are highly complex because, unlike some other types of cancer, the presence or absence of a single gene or a limited number of genes has not been shown to accurately predict the risk of metastasis or recurrence. Rather, we believe that risk of metastasis or recurrence of skin cancer requires the analysis of gene expression profiles occurring at the RNA level through the application of artificial intelligence, deep learning and proprietary techniques to identify clinically relevant genomic patterns. Once identified, we then undertake extensive clinical validation and clinical utility studies to develop products that address key unmet medical needs for patients and physicians.

TABLE OF CONTENTS

DecisionDx-Melanoma
In cutaneous melanoma, nearly every treatment plan decision is based upon a patient’s risk of metastasis and the traditional clinical and pathology factors that are used to estimate population-based rates of metastasis can be inaccurate predictors of an individual patient’s risk. A primary tumor diagnostic biopsy is used to identify most of these factors, such as tumor thickness and ulceration status. These factors then assist physicians in their decision of whether to discuss or recommend a second procedure, the invasive sentinel lymph node biopsy, or SLNB, surgery which can provide additional prognostic information.
However, the clinical and pathology factors that lead to a recommendation to perform the SLNB surgery have limitations in that they are not very predictive when it comes to the likelihood that the patient will have an SLN-positive biopsy result, meaning that melanoma cells are found in the sentinel lymph nodes. In fact, approximately 88% of patients who undergo the SLNB surgery are found to have an SLN-negative biopsy result, and these patients remain either as Stage I, the lowest risk group, or as Stage II, the next lowest risk group. Unfortunately, despite being classified as low risk, two out of three patients who develop metastatic disease and die from the primary melanoma tumor received an SLN-negative biopsy result remained classified as Stage I or II following SLNB surgery. The significant diagnostic discordance that exists between the clinical and pathologic factors and likelihood of both an SLN-positive biopsy result and the risk of metastasis or recurrence has led to an opportunity to improve care by adding personalized genomic information.
We developed our proprietary, non-invasive genomic DecisionDx-Melanoma product to address this diagnostic discordance in patients with Stage I-III cutaneous melanoma. The product interrogates the biology of a patient’s tumor by analyzing the gene expression profile of 31 genes, a process made possible by our proprietary algorithm, developed using machine learning techniques. DecisionDx-Melanoma reports the risk of metastasis or recurrence for a patient’s melanoma into two classes and two subclasses, ranging from Class 1A, the lowest risk group, through Class 2B, the highest risk group, based on the genomics of the patient’s tumor. Physicians and patients use this additional tumor-specific genomic information, along with traditional staging criteria, to make better-informed decisions about how to manage the disease.
Twenty-five peer-reviewed studies have been published that support the two current clinically actionable uses of DecisionDx-Melanoma. The first use immediately following diagnosis is based upon a patient’s likelihood of having an SLN-negative biopsy result so that physicians and their patients can discuss the risk and benefit of undergoing the SLNB surgery. Data from our independent prospective multi-center study of 1,421 patients showed that the 1,065 patients with a melanoma less than or equal to 2.0 mm thick, defined as T1-T2 melanoma, and who received a DecisionDx-Melanoma Class 1A test result, had only a 4.6% likelihood of an SLN-positive biopsy result. This is clinically relevant because current guidelines do not recommend offering the SLNB surgery if the likelihood of an SLN-positive biopsy result is 5% or less. Therefore, all patients with a T1-T2 melanoma and a DecisionDx-Melanoma Class 1A test result, which represented approximately 70% of all T1-T2 patients in our study, could avoid the SLNB surgery based on current guidelines. We recently completed analysis from a second, independent prospective multi-center study of 1,690 patients. This study confirmed data from the first study in that patients with a T1-T2 melanoma who received a DecisionDx-Melanoma Class 1A test result had a 4.5% likelihood of an SLN-positive biopsy result. The second use of our product is to inform the appropriate treatment plan, regardless of the decision to undergo or avoid the SLNB surgery. The aggregate data from all of our published long-term archival studies showed a 99.6% negative predictive value, or NPV, for melanoma-specific survival at five years for patients who received a DecisionDx-Melanoma Class 1A test result; meaning that at the five-year mark, 99.6% of patients with a Class 1A test result did not die from their melanoma. We have also demonstrated, in all four of our clinical impact studies, that physicians changed their treatment plans approximately 50% of the time after receiving our test results, showing that DecisionDx-Melanoma can significantly change the way physicians treat their patients. For contextual purposes, note that for patients who undergo the SLNB surgery, only 12% are SLNB positive, while the remaining 88% are SLNB negative. This means that only 12% would have a change in management.
DecisionDx-UM
We also market DecisionDx-UM, a genomic test for use in identifying patients diagnosed with uveal melanoma who are at a low risk of metastasis. Uveal melanoma is a rare but deadly eye cancer with approximately 1,600 patients diagnosed in the United States annually. Similar to DecisionDx-Melanoma, this product also uses a proprietary algorithm developed using machine learning techniques to interrogate the biology of a patient’s tumor by analyzing the gene expression profile of 15 genes of a patient’s tumor. Because approximately 30% of uveal melanoma patients go on to metastasize within three years, prior to the availability of DecisionDx-UM in 2010, once the primary eye

tumor was treated, nearly all patients were managed under an aggressive metastatic surveillance treatment plan. Similar to our efforts to develop evidence for DecisionDx-Melanoma, we have supported development of an expansive, peer-reviewed publication dataset with 17 studies documenting the validity and utility of DecisionDx-UM. The first prospective, multi-center study reported a 98% NPV at five years for metastatic-free survival for patients who received a Class 1A test result. Based upon this and additional clinical validity data, two clinical impact studies we conducted reported that over 90% of post-diagnostic management decisions align with the DecisionDx-UM results.
Pipeline Products
We are developing additional products targeting the challenges faced by physicians in treating their patients’ skin cancer, with two products in late stage development.
DecisionDx-SCC
One of our pipeline products, DecisionDx-SCC, is a proprietary GEP test designed to predict the risk of metastasis in patients diagnosed with high-risk SCC. We estimate that approximately one million patients are diagnosed with SCC in the United States each year and, of these patients, we further estimate that approximately 200,000 patients are identified as having high-risk SCC, meaning that they have one or more high-risk features associated with their SCC. The current treatment pathway for patients with high-risk SCC suffers from a low positive predictive value for risk of metastasis or recurrence. As a result, many patients categorized as high risk receive adjuvant therapy and other unnecessary medical and surgical interventions even though they would not have gone on to metastasize. Conversely, there are also many patients categorized as high-risk who are placed in “a watchful waiting treatment plan” who could benefit from adjuvant therapy. To address this clinical need in high-risk SCC, we developed and validated DecisionDx-SCC, a proprietary GEP test designed to be used in patients with one or more high-risk features in order to improve treatment plan decisions by incorporating personalized genomic information provided by DecisionDx-SCC.
We recently published three studies regarding DecisionDx-SCC: our clinical validation study and two clinical use studies. Importantly, we demonstrated that applying the genomic profile of the SCC tumor using DecisionDx-SCC improves identification of high-risk SCC patients who are actually at low risk and the resultant group is at a much higher risk of metastasis than clinical or pathologic factors, alone, would predict. In parallel our two initial clinical use studies have identified a framework for integration of DecisionDx-SCC into existing management pathways for a risk-appropriate approach in high-risk SCC patients, designed to align treatment plans with predicted risk of metastasis using clinical, pathologic and genomic profile information. Separately, we also announced the publication of an intended use study involving 162 clinicians attending a national dermatology conference, which demonstrated that integration of DecisionDx-SCC test results impacted management decisions in a significant and risk-appropriate manner for high-risk SCC patient scenarios, while remaining aligned with national guidelines for patient management. Based on these published results, we have announced our intention to make this test clinically available in the third quarter of 2020.
DecisionDx for Suspicious Pigmented Lesions
We also recently completed development of a proprietary GEP test designed to assist physicians in the diagnosis of suspicious pigmented lesions. Of the approximately two million pigmented lesion skin biopsies performed for the diagnosis of melanoma annually in the United States, we estimate that approximately 300,000 biopsy specimens cannot be confidently confirmed as a melanoma or a benign lesion through the use of histopathology alone. We recently completed our clinical validation study and based on the estimated completion timing of our additional clinical studies, we believe we remain on track to launch this product in the second half of 2020.
Our Commercial Channel
We have built a commercial organization that focuses on providing solutions to dermatologists, including Mohs surgeons, surgeons and dermatological pathologists who care for patients with skin cancer. Our focus on dermatologic cancers has provided us with unique insights into the challenges faced by these physicians that have enabled us to drive adoption of DecisionDx-Melanoma, as well as to identify opportunities for additional products to address unmet clinical needs in dermatologic cancers and medical dermatology. We have processed over 60,000 clinical samples since commercial launch, with total proprietary GEP report volume increasing from less than 4,000 in 2015 to more

than 17,000 in 2019. Our annual revenue increased from $22.8 million in 2018 to $51.9 million in 2019. During 2019, we also expanded our commercial and medical affairs organizations from the low 20s to the low 50s in externally facing employees, including expansion of our outside sales territories from 14 in January 2019 to 23 in February 2019 to 32 in December 2019 with the additional expansion coming from our inside sales support and our medical affairs group, to further educate physicians, which we believe drives adoption of our products. We will continue to develop evidence, including performance and utility data, to substantiate the value of our marketed products, which we believe is important for physicians as they adopt our products for multiple uses. We will also continue to evaluate our mix of outside sales territories, inside sales support, marketing and medical affairs and adjust our investments based upon these evaluations. We will also continue to evaluate other pipeline product opportunities and invest in those that we believe will solve clinically significant unmet needs.

Our Products
We currently market two proprietary products, DecisionDx-Melanoma and DecisionDx-UM, and have two late-stage proprietary products for which we have completed clinical validation. We believe these commercial and pre-commercial products support an estimated total addressable market of approximately $2.0 billion in the United States. We have received positive local coverage determinations, or LCDs, providing Medicare coverage for both of our commercial products. These LCDs facilitate reimbursement from Medicare, which represents approximately 50% of the addressable patient population.

Recent Updates
Cash and Cash Equivalents
As of May 31, 2020, we had cash and cash equivalents of approximately $109.9 million, and the outstanding principal balance on our bank term loan was $26.7 million. This amount of cash and cash equivalents is preliminary, subject to adjustment and based solely upon information available to us as of the date of this prospectus. It includes an $8.3 million advance payment received from the Centers for Medicare & Medicaid Services, which will be applied against future Medicare claims we submit for reimbursement in 2020 and will increase our liabilities when recorded in the second quarter of 2020. This amount of cash and cash equivalents is not a comprehensive statement of our results of operations, liquidity or financial condition as of May 31, 2020, including with respect to our liabilities as of May 31, 2020, and has not been audited or reviewed by our independent registered public accounting firm. This amount is not intended to be indicative of expected cash and cash equivalents as of June 30, 2020, or other future fiscal periods. Accordingly, undue reliance should not be placed on this preliminary information, and it should be viewed in the context of all other available information regarding our results of operations, liquidity and financial condition.
COVID-19 Update
As previously reported, we recently experienced a decline in orders, which we believe is linked to delays and/or cancellations in patient visits, resulting in reduced diagnostic biopsies and thus reduced diagnoses of cutaneous melanoma in response to COVID-19. For example, we disclosed that from April 1, 2020 to May 6, 2020, orders for our lead product, DecisionDx-Melanoma, declined 43% as compared to the same period in 2019. While we are unable to predict the pace, timing or occurrence of any rescheduled patient visits, we anticipate that a majority of these delayed and/or canceled patient visits will be subsequently rescheduled throughout 2020 as state and local government restrictions and guidelines are eased, which we believe is supported by recent metrics available to us. For example, weekly orders of DecisionDx-Melanoma in the first three weeks of June were 96% of the weekly order volume of the first three weeks of January 2020.
As the overall effect of COVID-19 on our business is continuing to evolve, we cannot predict the extent to which our results of operations, financial condition or cash flows will be impacted by COVID-19. Accordingly, the information presented above is not necessarily indicative of our results of operations that can be expected for the three months ending June 30, 2020, or any other interim period, or for the year ending December 31, 2020. For more information on the potential impact of the COVID-19 pandemic on our business, see the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section and the risk factors included under “Risks Related to Our Business” and the other risk factors included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, filed with the SEC on May 11, 2020.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company
We qualify as an emerging growth company as defined in the Jumpstart Our Business Startups Act, as amended, or the JOBS Act, enacted in April 2012. An emerging growth company may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:
being permitted to present only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and Results of Operations in this prospectus;
not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;
reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved.
We may take advantage of these reporting exemptions until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of (1) December 31, 2024, (2) the last day of the fiscal year (a) in which we have total annual gross revenue of at least $1.07 billion or (b) in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the prior June 30th, and (3) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.
In addition, the JOBS Act provides that an emerging growth company can leverage the extended transition period, provided in Section 102(b) of the JOBS Act, for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. We have elected to use this extended transition period and, as a result, our financial statements may not be comparable to companies that comply with public company effective dates.
We are also a smaller reporting company as defined in the Exchange Act (and may continue to qualify as such even after we no longer qualify as an emerging growth company) and accordingly may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis of financial condition and results of operations disclosure.
We have elected to take advantage of certain of the reduced disclosure obligations in this prospectus and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be different from what you might receive from other public reporting companies in which you hold equity interests.

You should consider carefully the following risks and uncertainties as well as the risks and uncertainties described in the section entitled “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the Securities and Exchange Commission, or SEC, on March 10, 2020, as well as in our subsequent filings with the SEC, which descriptions are incorporated in this prospectus by reference in their entirety. These risks and uncertainties are not the only risks and uncertainties we face. Additional risks and uncertainties not currently known to us, or that we currently view as immaterial, may also impair our business. If any of the following risks occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of a number of factors, including the risks described below. See “Special Note Regarding Forward-Looking Statements.”
Risks Related to this Offering and Ownership of Our Common Stock
If you purchase shares of our common stock in this offering, you will experience substantial and immediate dilution.
Since the price per share of our common stock being offered is substantially higher than the net tangible book value per share of our common stock, you will suffer immediate and substantial dilution with respect to the net tangible book value of the common stock you purchase in this offering. Based on the assumed public offering price of $42.38 per share of common stock being sold in this offering, which was the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020, and our net tangible book value as of March 31, 2020, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of $34.51 per share with respect to the net tangible book value of the common stock. See the section entitled “Dilution” for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering.
If we issue additional shares of common stock, or securities convertible into or exchangeable or exercisable for shares of common stock, our stockholders, including investors who purchase shares of common stock in this offering, will experience additional dilution, and any such issuances may result in downward pressure on the price of our common stock. We also cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders.
Future sales of substantial amounts of our common stock, or the possibility that such sales could occur, could adversely affect the market price of our common stock.
Future sales in the public market of shares of our common stock, including shares referred to in the foregoing risk factor or shares issued upon exercise of our outstanding stock options, or the perception by the market that these sales could occur, could lower the market price of our common stock or make it difficult for us to raise additional capital.
We will have broad discretion in the use of the net proceeds of this offering and may not use them effectively or in ways that increase the value of our share price.
We will have broad discretion in the application of the net proceeds from this offering, including for any purposes described in the section titled “Use of Proceeds,” and you and other stockholders may disagree with how we spend or invest these proceeds. The failure by our management to apply these funds effectively could adversely affect our business and financial condition. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

This prospectus and the documents incorporated by reference herein contain forward-looking statements that reflect our beliefs and views with respect to future events and are subject to substantial risks and uncertainties within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, Section 21E of the Exchange Act and the safe harbor provisions for the U.S. Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, contained in this prospectus and the documents incorporated by reference herein, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans and objectives of management, are forward-looking statements.

We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions, including risks described in “Risk Factors” and elsewhere in this prospectus and the documents incorporated by reference herein, regarding, among other things:

expectations with respect to reimbursement for our products, including third-party payor reimbursement and coverage decisions;
anticipated cost, timing and success of our products in development, and our plans to research, develop and commercialize new tests;
the impact of the COVID-19 pandemic on our business;
our ability to obtain funding for our operations, including funding necessary to complete the expansion of our operations and development of our product candidates;
the implementation of our business model and strategic plans for our products, technologies and businesses;
our ability to manage and grow our business by expanding our sales to existing customers or introducing our products to new customers;
our ability to develop and maintain sales and marketing capabilities;

our expectations regarding our ability to obtain and maintain intellectual property protection for our products and our ability to operate our business without infringing on the intellectual property rights of others.
We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements. We operate in a very competitive and rapidly changing environment. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make, and accordingly you should not place undue reliance on our forward-

looking statements. We have included important factors in the cautionary statements included in this prospectus, particularly in the “Risk Factors” section in this prospectus and the documents incorporated by reference herein, that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make.
You should read this prospectus, the documents incorporated by reference herein and the documents that we have filed as exhibits to the registration statement of which this prospectus is a part completely and with the understanding that our actual future results may be materially different from what we expect.

TABLE OF CONTENTS

USE OF PROCEEDS
We estimate that we will receive net proceeds of approximately $59.3 million (or approximately $68.2 million if the underwriters’ option to purchase additional shares is exercised in full) from the sale of the shares of common stock offered by us in this offering, assuming a public offering price of $42.38 per share, which was the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.
A $1.00 increase or decrease in the assumed public offering price of $42.38 per share would increase or decrease the expected net proceeds of the offering to us by approximately $1.4 million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. An increase or decrease of  300,000 shares from the assumed number of shares sold in this offering would increase or decrease the expected net proceeds of the offering to us by approximately $12.0 million, assuming the public offering price of $42.38 per share remains the same, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.
The principal purpose of our sale and issuance of our common stock in this offering is to obtain additional capital to support our operations. As of the date of this prospectus, we have no specific plan for the use of the net proceeds from this offering, or any significant portion thereof. However, we intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, to further support and increase our research and development activities, including those to support the development of our product pipeline, to expand our commercial organization including our sales force and for working capital and other general corporate purposes. We may also use a portion of our net proceeds to co-develop, acquire or invest in products, technologies or businesses that are complementary to our business. However, we currently have no agreements or commitments to complete any such transaction.
Our management will have broad discretion in the application of the net proceeds from this offering, and investors will be relying on the judgment of our management regarding the application of those net proceeds. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. Pending their use, we may invest the net proceeds from this offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

We may also increase or decrease the number of shares we are offering. A 300,000 share increase (decrease) in the number of shares offered by us, as set forth on the cover page of this prospectus, would increase (decrease) the as adjusted amount of each of cash and cash equivalents, additional paid-in capital, total stockholders’ equity and total capitalization by approximately $12.0 million, assuming that the assumed public offering price of $42.38 per share, which is the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

TABLE OF CONTENTS

DILUTION
If you invest in our common stock, your ownership interest will be diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock after this offering.
As of March 31, 2020, our historical net tangible book value was $87.9 million, or $5.11 per share of common stock. Our historical net tangible book value is the amount of our total tangible assets less our total liabilities. Historical net tangible book value per common share is our historical net tangible book value divided by the number of shares of common stock outstanding as of March 31, 2020.
After giving effect to the sale of shares of common stock in this offering at an assumed public offering price of $42.38 per share, which was the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of March 31, 2020 would be $147.2 million, or $7.87 per share of common stock. This amount represents an immediate increase in as adjusted net tangible book value of $2.76 per share to our existing stockholders and an immediate dilution of $34.51 per share to investors participating in this offering. We determine dilution per share to investors participating in this offering by subtracting as adjusted net tangible book value per share after this offering from the assumed public offering price per share paid by investors participating in this offering.
The following table illustrates this dilution:
 
 
Assumed public offering price per share
   
$42.38
Historical net tangible book value per share as of March 31, 2020
$5.11
 
Increase in historical net tangible book value per share attributable to this offering
$2.76
 
As adjusted net tangible book value per share after this offering
 
$7.87
Dilution per share to new investors participating in this offering
 
$34.51
The as adjusted dilution information discussed above is illustrative only and will change based on the actual public offering price. Each $1.00 increase (decrease) in the assumed public offering price of $42.38 per share, which was the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020, would increase (decrease) the as adjusted net tangible book value per share after this offering by approximately $0.08, and dilution in net tangible book value per share to new investors by approximately $0.92, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and the estimated offering expenses payable by us.
We may also increase or decrease the number of shares we are offering. An increase of 300,000 shares in the number of shares offered by us, as set forth on the cover page of this prospectus, would increase our as adjusted net tangible book value per share after this offering by approximately $0.50 and decrease the dilution to investors participating in this offering by approximately $0.50 per share, assuming that the assumed public offering price remains the same, and after deducting the estimated underwriting discounts and commissions and the estimated offering expenses payable by us. Similarly, a decrease of 300,000 shares in the number of shares offered by us, as set forth on the cover page of this prospectus, would decrease the as adjusted net tangible book value per share after this offering by approximately $0.52 and increase the dilution to investors participating in this offering by approximately $0.52 per share, assuming that the assumed public offering price remains the same, and after deducting the estimated underwriting discounts and commissions and the estimated offering expenses payable by us.
If the underwriters exercise their option to purchase additional shares of our common stock in full in this offering, the as adjusted net tangible book value after the offering would be $8.25 per share, the increase in as adjusted net tangible book value per share to existing stockholders would be $3.14 per share and the dilution per share to new investors would be $34.13 per share, in each case assuming a public offering price of $42.38 per share, which was the last reported sale price of our common stock on the Nasdaq Global Market on June 19, 2020.
The information discussed above is illustrative only and will be adjusted based on the actual public offering price, the actual number of shares that we offer in this offering, and other terms of this offering determined at pricing. We may choose to raise additional capital through the sale of equity or convertible debt securities due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent we issue additional shares of common stock or other equity or convertible debt securities in the future, there will be further dilution to investors participating in this offering.

TABLE OF CONTENTS

PRINCIPAL STOCKHOLDERS
The following table sets forth information regarding beneficial ownership of our capital stock by:
each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;
each of our directors;
our named executive officers; and
all of our current executive officers and directors as a group.
The percentage ownership information under the column entitled “Before Offering” is based on 17,360,096 shares of common stock outstanding as of May 29, 2020.
The percentage ownership information under the column entitled “After Offering” is based on the sale of 1,500,000 shares of common stock in this offering, assuming no exercise of the underwriters’ option to purchase additional shares.
We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options that are either immediately exercisable or exercisable on or before July 28, 2020, which is 60 days after May 29, 2020. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.
The following table is based upon information supplied by officers, directors and principal stockholders and Schedules 13D and 13G, if any, filed with the SEC. Unless otherwise indicated in the footnotes to this table and subject to community property laws where applicable, we believe that each of the stockholders named in this table has sole voting and investment power with respect to the shares indicated as beneficially owned. Except as otherwise noted below, the address for each person or entity listed in the table is c/o Castle Biosciences, Inc., 820 S. Friendswood Drive, Suite 201, Friendswood, Texas 77546.

TABLE OF CONTENTS

Investor Agreements
In connection with our preferred stock financings described above, we entered into amendments of our existing investor rights agreement, voting agreement and right of first refusal and co-sale agreement, which contain voting rights, information rights, rights of first refusal and co-sale and registration rights, among other things, with certain of our stockholders. These rights terminated upon the closing of the IPO, except for the registration rights, which will expire upon the earliest to occur of (1) July 29, 2024 and (2) the consummation of a liquidation event.
Stock Options Granted to Executive Officers and Directors
Pursuant to our Non-Employee Director Compensation Policy, on June 4, 2020, we granted each member of our board of directors who is not also serving as an employee or consultant to us an option to purchase 8,000 shares of our common stock, at an exercise price of $37.50 per share, all of which vest on June 4, 2021.
Separation and Consulting Agreements
On May 29, 2020, in connection with his resignation as Chief Medical Officer of the Company, the Company entered into an Employment Separation Agreement, or Separation Agreement, with Federico A. Monzon, M.D., and a Master Services Agreement, or the Consulting Agreement, with Genomic Path LLC, a consulting firm wholly owned by Dr. Monzon, or the Consultant, pursuant to which Dr. Monzon will provide consulting services to the Company.
Under the Separation Agreement, which contains a customary release of claims in favor of the Company, (i) Dr. Monzon will receive a cash payment for his accrued salary and paid time off through May 31, 2020, subject to standard withholdings and deductions, (ii) the Company agreed to enter into the Consulting Agreement and (iii) Dr. Monzon’s outstanding equity awards will continue to vest and remain exercisable in accordance with their terms during the term of the Consulting Agreement.
The Consulting Agreement provides that the Consultant will provide certain services to the Company on a project basis from time to time at a rate of $350.00 per hour. The Consulting Agreement has an initial term through May 31, 2021, which may be renewed for consecutive one-year periods by mutual written agreement. The Consulting Agreement also requires the Consultant to adhere to non-solicitation and non-interference restrictions for a period of three years following termination of the Consulting Agreement and non-competition restrictions for a period of one year following termination of the Consulting Agreement. Among other termination provisions, the Company has the right to terminate the Consulting Agreement immediately for any reason with or without prior notice.
Indemnification Agreements
We have entered, and intend to continue to enter, into separate indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our amended and restated bylaws. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at our request. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.
The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder’s investment may decline in value to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

TABLE OF CONTENTS

DESCRIPTION OF COMMON STOCK
General
The following description summarizes the most important terms of our common stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth in this “Description of Common Stock,” you should refer to our amended and restated certificate of incorporation (the “Restated Certificate”) and amended and restated bylaws (the “Restated Bylaws”), which are included as exhibits to our Annual Report on Form 10-K, and to the applicable provisions of the Delaware General Corporation Law (the “DGCL”). Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share. Our board of directors has the authority, without stockholder approval, except as required by the listing standards of The Nasdaq Stock Market LLC, to issue additional shares of our capital stock. In addition, our board of directors has the authority, without further action by our stockholders, to designate the rights, preferences, privileges, qualifications and restrictions of our preferred stock in one or more series.
As of May 29, 2020, there were approximately 132 holders of record our common stock, which does not include shares held in street name.
Voting
Our common stock is entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors, and does not have cumulative voting rights. Except as otherwise provided by statute or by applicable stock exchange rules, or by the Restated Certificate or the Restated Bylaws, (i) in all matters other than the election of directors, the affirmative vote of the majority of shares present in person, by remote communication, if applicable, or represented by proxy at a meeting of stockholders and entitled to vote generally on the subject matter shall be the act of the stockholders, and (ii) directors shall be elected by a plurality of the votes of the shares present in person, by remote communication, if applicable, or represented by proxy at a meeting of stockholders and entitled to vote generally on the election of directors. Exceptions to this include removing directors for cause and amending our Restated Certificate and Restated Bylaws, each of which will require the approval of the holders of at least 66-2/3% of the voting power of all then-outstanding shares of capital stock entitled to vote generally at an election of directors.
Dividends
Subject to preferences that may be applicable to any then-outstanding preferred stock, the holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.
Liquidation, Dissolution or Winding Up
In the event of our liquidation, dissolution or winding-up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.
Other Rights and Preferences
Holders of our common stock have no preemptive, conversion or subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.
Board of Directors
Our board of directors is divided into three classes. At each annual meeting of stockholders, the successors to directors whose terms then expire will serve until the third annual meeting following their election and until their successors are duly elected and qualified.

TABLE OF CONTENTS

Registration Rights
Certain holders of shares of our common stock, including certain holders of five percent of our capital stock and entities affiliated with certain of our directors, are entitled to certain rights with respect to registration of shares held by such persons or entities under the Securities Act. These shares are referred to as registrable securities. The holders of these registrable securities possess registration rights pursuant to the terms of an investors’ rights agreement and are described in additional detail below.
The registration of shares of our common stock pursuant to the exercise of the registration rights described below would enable the holders to trade these shares without restriction under the Securities Act when the applicable registration statement is declared effective. We are required to pay all registration expenses, other than underwriting discounts, selling commissions and stock transfer taxes of the shares registered pursuant to the demand, piggyback and Form S-3 registrations described below.
Generally, in an underwritten offering, the managing underwriter, if any, has the right, subject to specified conditions, to limit the number of shares the holders may include. The demand, piggyback and Form S-3 registration rights described below will expire upon the earliest to occur of (1) July 29, 2024 and (2) the consummation of a liquidation event.
Demand Registration Rights
The holders of the registrable securities are entitled to certain demand registration rights. Subject to the terms of the lockup agreements described under “Underwriters,” the holders of at least 50% of the registrable securities then outstanding may make a written request that we register all or a portion of their shares, subject to certain specified exceptions. Such request for registration must cover securities that have an aggregate offering price that exceeds $10,000,000. We will not be required to effect more than two registrations pursuant to these demand registration rights.
Piggyback Registration Rights
In connection with this offering, the holders of registrable securities were entitled to, and the necessary percentage of holders waived, their rights to notice of this offering and to include their shares of registrable securities in this offering. If we propose to register for offer and sale any of our securities under the Securities Act in another offering, either for our own account or for the account of other security holders, the holders of registrable securities will be entitled to certain “piggyback” registration rights allowing them to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, including a registration statement on Form S-3 as discussed below, other than with respect to a demand registration or a registration statement on Forms S-4 or S-8, the holders of these shares are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration.
Form S-3 Registration Rights
The holders of the registrable securities are entitled to certain Form S-3 registration rights. Holders of at least 10% of the registrable securities may request that we register for offer and sale their shares on Form S-3 if we are qualified to file a registration statement on Form S-3, subject to certain specified exceptions. Such request for registration on Form S-3 must cover securities the aggregate offering price of which exceeds $1,000,000. We will not be required to effect more than one registration on Form S-3 within any six-month period.
Anti-Takeover Effects of Provisions of Our Amended and Restated Certificate of Incorporation, Our Amended and Restated Bylaws and Delaware Law
Delaware Anti-Takeover Law
We are subject to Section 203 of the DGCL, which generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the time that such stockholder became an interested stockholder, unless:
prior to such time the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation
22

TABLE OF CONTENTS

outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder.
Section 203 defines a business combination to include:
any merger or consolidation involving the corporation and the interested stockholder;
any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;
subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; and
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.
The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.
Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws
Provisions of our Restated Certificate and our Restated Bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our Restated Certificate and our Restated Bylaws:
permit our board of directors to issue up to 10,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate (including the right to approve an acquisition or other change in our control);
provide that the authorized number of directors may be changed only by resolution of the board of directors;
provide that the board of directors or any individual director may only be removed with cause and the affirmative vote of the holders of at least 66 2/3% of the voting power of all of our then-outstanding common stock;
provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;
divide our board of directors into three classes;
require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent;
provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and also specify requirements as to the form and content of a stockholder’s notice;
23

TABLE OF CONTENTS

do not provide for cumulative voting rights (therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose);
provide that special meetings of our stockholders may be called only by the chairman of the board, our Chief Executive Officer or by the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors;
provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or other employees to us or our stockholders; (iii) any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees, arising out of or pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws; (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or our bylaws; (v) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any action asserting a claim against us or any of our directors, officers or other employees governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants; provided these provisions of our amended and restated certificate of incorporation and amended and restated bylaws will not apply to suits brought to enforce a duty or liability created by the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction; and
provide that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision.
The amendment of any of these provisions, with the exception of the ability of our board of directors to issue shares of preferred stock and designate any rights, preferences and privileges thereto, would require approval by the holders of at least 66-2/3% of our then-outstanding common stock.
The foregoing provisions may make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.
These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are also designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in our control or management. As a consequence, these provisions also may inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts.
Exchange Listing
Our common stock is listed on The Nasdaq Global Market and trades under the symbol “CSTL.”

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.
The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
Commissions and Discounts
The representatives have advised us that the underwriters propose to initially offer the shares to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $     per share. After the initial offering of the shares, the public offering price, concession or any other term of the offering may be changed.
The following table shows the public offering price, underwriting discount and proceeds before expenses to us. The information assumes either no exercise or full exercise by the underwriters of their option to purchase additional shares of our common stock.

No Sales of Similar Securities
We, our executive officers and our directors have agreed not to sell or transfer any common stock or securities convertible into or exchangeable or exercisable for common stock, for 90 days after the date of this prospectus without first obtaining the written consent of SVB Leerink LLC and Robert W. Baird & Co. Incorporated on behalf of the underwriters. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:
offer, pledge, sell or contract to sell any common stock;
sell any option or contract to purchase any common stock;
purchase any option or contract to sell any common stock;
grant any option, right or warrant for the sale of any common stock;
otherwise dispose of or transfer any common stock;
exercise any right with respect to the registration of any common stock, or file or cause to be filed any registration statement in connection therewith; or
enter into any swap or other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any common stock, whether any such swap, agreement or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.
The lock-up provisions apply to common stock and to securities convertible into or exchangeable or exercisable for common stock. They also apply to common stock owned now or acquired later by the person executing the lock-up agreement or for which the person executing the lock-up agreement later acquires the power of disposition. Except for customary lock-up exceptions, including an exception allowing our directors and officers to make sales under preexisting 10b5-1 plans, there are no existing agreements between the underwriters and any of our stockholders who have executed a lock-up agreement providing consent to the sale of shares prior to the expiration of the lock-up period.
Nasdaq Global Market Listing
Our common stock is listed on the Nasdaq Global Market under the symbol “CSTL.”
Price Stabilization, Short Positions and Penalty Bids
Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.
In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option described above. The underwriters may close out any covered short position by either exercising their option or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.
The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.
Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the
26

TABLE OF CONTENTS

market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the Nasdaq Global Market, in the over-the-counter market or otherwise.
Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
Electronic Distribution
In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.
Other Relationships
The underwriters and their affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. For instance, Silicon Valley Bank, a lender under our loan agreement, is an affiliate of SVB Leerink LLC, one of the underwriters in this offering.
In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Item 14. Indemnification of Directors and Officers.
We are incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any persons who were, are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. A Delaware corporation may indemnify any persons who were, are, or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses (including attorneys’ fees) actually and reasonably incurred.
Our amended and restated certificate of incorporation and amended and restated bylaws, respectively, provide for the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law. Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:
transaction from which the director derives an improper personal benefit;
act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
unlawful payment of dividends or redemption of shares; or
breach of a director’s duty of loyalty to the corporation or its stockholders.
II-1

TABLE OF CONTENTS

Our amended and restated certificate of incorporation includes such a provision. Expenses incurred by any officer or director in defending any such action, suit or proceeding in advance of its final disposition shall be paid by us upon delivery to it of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified by us.
Section 174 of the Delaware General Corporation Law provides, among other things, that a director who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption may be held liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.
As permitted by the Delaware General Corporation Law, we have entered into indemnity agreements with each of our directors and executive officers, that require us to indemnify such persons against any and all costs and expenses (including attorneys’, witness or other professional fees) actually and reasonably incurred by such persons in connection with any action, suit or proceeding (including derivative actions), whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer or is or was acting or serving as an officer, director, employee or agent of us or any of our affiliated enterprises. Under these agreements, we are not required to provide indemnification for certain matters, including:
indemnification beyond that permitted by the Delaware General Corporation Law;
indemnification for any proceeding with respect to the unlawful payment of remuneration to the director or officer;
indemnification for certain proceedings involving a final judgment that the director or officer is required to disgorge profits from the purchase or sale of our stock;
indemnification for proceedings involving a final judgment that the director’s or officer’s conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct or a breach of his or her duty of loyalty, but only to the extent of such specific determination;
indemnification for proceedings or claims brought by an officer or director against us or any of our directors, officers, employees or agents, except for claims to establish a right of indemnification or proceedings or claims approved by our board of directors or required by law;
indemnification for settlements the director or officer enters into without our consent; or
indemnification in violation of any undertaking required by the Securities Act of 1933, as amended, or the Securities Act, or in any registration statement filed by us.
The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.
We have an insurance policy in place that covers our officers and directors with respect to certain liabilities, including liabilities arising under the Securities Act, or otherwise.
We plan to enter into an underwriting agreement which provides that the underwriters are obligated, under some circumstances, to indemnify our directors, officers and controlling persons against specified liabilities, including liabilities under the Securities Act.
Item 15. Recent sales of unregistered securities.
Set forth below is information regarding securities issued and options granted by us since January 1, 2017 that were not registered under the Securities Act.

Each of the recipients of securities in these transactions was an accredited investor under Rule 501 of Regulation D. No underwriters were involved in these transactions.
The offers, sales and issuances of the securities described in paragraph (9) were deemed to be exempt from registration under the Securities Act in reliance on either Rule 701 in that the transactions were under compensatory benefit plans and contracts relating to compensation as provided under Rule 701 or Section 4(a)(2) in that the

Item 17. Undertakings.
The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
The undersigned Registrant hereby undertakes that:
(a)
For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
(b)
For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:
 
Castle Biosciences, Inc., a Delaware corporation (the “Company”), confirms its agreement with SVB Leerink LLC (“SVB Leerink”), Robert W. Baird & Co. Incorporated (“Baird”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for which SVB Leerink and Baird are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of shares of common stock, par value $0.001 per share, of the Company (“Common Stock”) set forth in Schedule A hereto and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of [ ] additional shares of Common Stock.  The aforesaid [ ] shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the [ ] shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are herein called, collectively, the “Securities.”
 
The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Underwriting Agreement (this “Agreement”) has been executed and delivered.
 
The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S‑1 (No. 333-[ ]), including the related preliminary prospectus or prospectuses, covering the registration of the sale of the Securities under the Securities Act of 1933, as amended (the “1933 Act”).  Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and Rule 424(b) (“Rule 424(b)”) of the 1933 Act Regulations.  The information included in such prospectus that was omitted from such registration statement at the time such registration statement became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to Rule 430A(b) is herein called the “Rule 430A Information.”  Such registration statement, including the amendments thereto, the exhibits thereto and any schedules thereto, and the documents incorporated by reference therein pursuant to Item 12 of Form S-1 under the 1933 Act, at the time it became effective, and including the Rule 430A Information, is herein called the “Registration Statement.”  Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein called the “Rule 462(b) Registration Statement” and, after such filing, the term “Registration Statement” shall include the Rule 462(b) Registration Statement.  Each prospectus used prior to the effectiveness of the Registration Statement, and each prospectus that omitted the Rule 430A Information that was used after such effectiveness and prior to the execution and delivery of this Agreement, including the documents incorporated by reference therein pursuant to Item 12 of Form S-1 under the 1933 Act, is herein called a “preliminary prospectus.”  The final prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-1 under the 1933 Act, is herein called the “Prospectus.”  For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system or any successor system (“EDGAR”).

(a)          Representations and Warranties by the Company.  The Company represents and warrants to each Underwriter as of the date hereof, the Applicable Time, the Closing Time (as defined below) and any Date of Delivery (as defined below), and agrees with each Underwriter, as follows:
 
(i)          Registration Statement and Prospectuses.  Each of the Registration Statement and any amendment thereto has become effective under the 1933 Act.  No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued by the Commission under the 1933 Act, no order preventing or suspending the use of any preliminary prospectus or the Prospectus has been issued by the Commission and no proceedings for any of those purposes have been instituted by the Commission or are pending or, to the Company’s knowledge, contemplated by the Commission.  The Company has complied with each request (if any) from the Commission for additional information.
 
Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.  Each preliminary prospectus, the Prospectus and any amendment or supplement thereto, at the time each was filed with the Commission, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.  Each preliminary prospectus delivered to the Underwriters for use in connection with the offering and the Prospectus was or will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.
 
The Registration Statement, any preliminary prospectus and the Prospectus, and the filing of the Registration Statement, any preliminary prospectus and the Prospectus with the Commission have been duly authorized by and on behalf of the Company, and the Registration Statement has been duly executed pursuant to such authorization.
 
The documents incorporated or deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus and the Prospectus, when they became effective or at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission under the 1934 Act (the “1934 Act Regulations”).

(ii)         Accurate Disclosure.  Neither the Registration Statement nor any amendment thereto, at its effective time, at the Closing Time or at any Date of Delivery, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.  As of the Applicable Time, none of (A) the General Disclosure Package, (B) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, nor (C) any individual Written Testing-the-Waters Communication, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.  Neither the Prospectus nor any amendment or supplement thereto (including any prospectus wrapper), as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Closing Time or at any Date of Delivery, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, at the time the Registration Statement became effective or when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, did not and will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.
 
The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto), the General Disclosure Package or the Prospectus (or any amendment or supplement thereto, including any prospectus wrapper) made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.  For purposes of this Agreement, the only information so furnished shall be the information in  the first paragraph under the heading “Underwriting—Commissions and Discounts,” the information in the first, second, third and fourth paragraphs under the heading “Underwriting—Price Stabilization, Short Positions and Penalty Bids” and the information under the heading “Underwriting—Electronic Distribution,” in each case contained in the Prospectus (collectively, the “Underwriter Information”).
 
(iii)        Incorporation of Documents by Reference.  The Company meets the requirements to incorporate documents by reference in the Registration Statement pursuant to General Instruction VII to Form S-1 under the 1933 Act and the 1933 Act Regulations.
 
(iv)        Issuer Free Writing Prospectuses.  No Issuer Free Writing Prospectus conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.  Any Issuer Free Writing Prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the 1933 Act and the 1933 Act Regulations.  Each Issuer Free Writing Prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act or that was prepared by or behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.  Except for the Issuer Free Writing Prospectuses, if any, identified in Schedule B-2 hereto, and electronic road shows, if any, each furnished to the Representatives before first use, the Company has not prepared, used or referred to, and will not, without the prior consent of the Representatives, prepare, use or refer to, any issuer free writing prospectus.

SECTION 2.        Sale and Delivery to Underwriters; Closing.
 
(a)          Initial Securities.  On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per share set forth in Schedule A, that number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, subject, in each case, to such adjustments among the Underwriters as the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional shares.
 
(b)        Option Securities.  In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional [ ˜ ] shares of Common Stock, at the price per share set forth in Schedule A, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities.  The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part at any time and from time to time upon notice by the Representatives to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities.  Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but any Date of Delivery after the Closing Time shall not be later than seven full business days nor earlier than two full business days after the exercise of said option, nor in any event prior to the Closing Time.  If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject, in each case, to such adjustments as the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional shares.
 
(c)          Payment.  Payment of the purchase price for, and delivery of certificates or security entitlements for, the Initial Securities shall be made at the offices of Latham & Watkins LLP, or at such other place as shall be agreed upon by the Representatives and the Company, at 10:00 A.M.

(New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Time”).  Delivery of the Initial Securities at the Closing Time shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.
 
16

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates or security entitlements for, such Option Securities shall be made at the above‑mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Company, on each Date of Delivery as specified in the notice from the Representatives to the Company.  Delivery of the Option Securities on each such Date of Delivery shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.
 
Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representatives for the respective accounts of the Underwriters of certificates or security entitlements for the Securities to be purchased by them (which delivery shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct).  It is understood that each Underwriter has authorized the Representatives, for their accounts, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase.  Each of SVB Leerink and Baird, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(l)         Additional Documents.  At the Closing Time and at each Date of Delivery (if any), counsel for the Underwriters shall have been furnished with such other documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Securities as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters.
 
(m)        Termination of Agreement.  If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement, or, in the case of any condition to the purchase of Option Securities on a Date of Delivery which is after the Closing Time, the obligations of the several Underwriters to purchase the relevant Option Securities, may be terminated by the Representatives by notice to the Company at any time at or prior to Closing Time or such Date of Delivery, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 4, 6, 7, 8, 14, 15 and 16 shall survive any such termination and remain in full force and effect.
 
SECTION 6.        Indemnification.
 
(a)          Indemnification of Underwriters.  The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”)), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:
 
23

 (i)        against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto), or (B) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, the General Disclosure Package, the Prospectus (or any amendment or supplement thereto) or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;
 
(ii)        against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company;
 
(iii)      against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;
 
provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including the Rule 430A Information, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.
 
(b)         Indemnification of Company, Directors and Officers.  Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.
 
24

(c)       Actions against Parties; Notification.  Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.
 
(d)         Settlement without Consent if Failure to Reimburse.  If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.
 
SECTION 7.      Contribution.  If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.
 
The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.
 
The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.
 
25

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.
 
Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.
 
No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.
 
For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.  The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.
 
SECTION 8.     Representations, Warranties and Agreements to Survive.  All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.
 
SECTION 9.       Termination of Agreement.
 
(a)          Termination.  The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in U.S. or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq Global Market, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.
 
26

(b)          Liabilities.  If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 4, 6, 7, 8, 14, 15 and 16 shall survive such termination and remain in full force and effect.
 
SECTION 10.    Default by One or More of the Underwriters.  If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non‑defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24‑hour period, then:
 
(i)         if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non‑defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non‑defaulting Underwriters, or
 
(ii)         if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non‑defaulting Underwriter.
 
No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.
 
In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements.  As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.
 
SECTION 11.     Notices.  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to SVB Leerink at 1301 Avenue of the Americas, 12th Floor, New York, New York 10019, attention of Stuart R. Nayman and to Baird at 777 East Wisconsin Avenue, Milwaukee, Wisconsin 53202, attention of Matt Deering.
 
27

SECTION 12.     No Advisory or Fiduciary Relationship.  The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.
 
SECTION 13.    Parties.  This Agreement shall each inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors.  Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.  This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.  No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.
 
SECTION 14.    Waiver of Trial by Jury.  The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates), and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.
 
SECTION 15.    GOVERNING LAW.  THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.
 
SECTION 16.    Consent to Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding.  Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court.  The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.
 
28

SECTION 17.     TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.
 
SECTION 18.     Partial Unenforceability.  The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.  If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.
 
SECTION 19.    Recognition of the U.S. Special Resolution Regimes.  (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United State.
 
(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
 
For purposes of this Section 19, a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).  “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b).  “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.  “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

Re:         Proposed Public Offering by Castle Biosciences, Inc.
 
Ladies and Gentlemen:
 
The undersigned, a stockholder, officer and/or director of Castle Biosciences, Inc., a Delaware corporation (the “Company”), understands that SVB Leerink LLC (“SVB Leerink”) and Robert W. Baird & Co. Incorporated (together with SVB Leerink, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company and certain selling stockholders to be named in the Underwriting Agreement (each, a “Selling Stockholder”) providing for the public offering (the “Public Offering”) of shares (the “Securities”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”).  In recognition of the benefit that such an offering will confer upon the Company, the Selling Stockholders and the undersigned as a stockholder, an officer and/or a director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement (collectively, the “Underwriters”) that, during the period beginning on the date hereof and ending at the end of the day on the date that is 90 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of the Representatives, on behalf of the Underwriters, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-Up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise.  If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Securities the undersigned may purchase in the Public Offering.
 

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer or otherwise dispose of Lock-Up Securities without the prior written consent of the Representatives, provided, in each case, that (1) in the case of transfers pursuant to clauses (i) – (v) below, the Representatives receive a signed lock-up agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, (2) in the case of transfers pursuant to clauses (i) – (iii) and (v) – (vi) below, any such transfer shall not involve a disposition for value, (3) in the case of transfers pursuant to clauses (i) – (vi) below, such transfers are not required to be reported with the Securities and Exchange Commission (the “SEC”) on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (4) in the case of transfers pursuant to clause (vii) below, any filing under Section 16 of the Exchange Act made in connection with such transfer shall clearly indicate in the footnotes thereto that the filing relates to the circumstances described in clause (vii), and (5) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers (other than a filing on a Form 5 made after the expiration of the Lock-Up Period):
 

(i)
as a bona fide gift or gifts;
 

(ii)
to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin);
 

(iii)
as a distribution or other transfer by a partnership to its partners or former partners or by a limited liability company to its members or retired members or by a corporation to its stockholders or former stockholders or to any wholly-owned subsidiary of such corporation;
 

(iv)
to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned;
 

(v)
pursuant to a qualified domestic relations order or in connection with a divorce settlement;
 

(vi)
by will or intestate succession upon the death of the undersigned; or
 

(vii)
to the Company in satisfaction of any tax withholding obligation.

Castle Biosciences, Inc.
820 S. Friendswood Drive, Suite 201
Friendswood, TX 77546

Ladies and Gentlemen:

We have acted as counsel to Castle Biosciences, Inc., a Delaware corporation (the “Company”), in connection with the filing by the Company of a Registration Statement on Form S‑1 (the “Registration Statement”) with the Securities and Exchange Commission, including a related prospectus included in the Registration Statement (the “Prospectus”), covering an underwritten public offering of up to 1,725,000 shares of the Company’s common stock, par value $0.001 (the “Shares”) (including up to 225,000 Shares that may be sold by the Company upon exercise of an over-allotment option to be granted to the underwriters).

In connection with this opinion, we have (i) examined and relied upon (a) the Registration Statement and Prospectus, (b) the Company’s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, as currently in effect, and (c) originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below and (ii) assumed that the Shares will be sold at a price established by the Board of Directors of the Company or a duly authorized committee thereof.  We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as copies, the accuracy, completeness and authenticity of certificates of public officials and the due authorization, execution and delivery of all documents by all persons other than the Company where authorization, execution and delivery are prerequisites to the effectiveness thereof.  As to certain factual matters, we have relied upon a certificate of an officer of the Company and have not independently verified such matters.

Our opinion is expressed only with respect to the General Corporation Law of the State of Delaware. We express no opinion to the extent that any other laws are applicable to the subject matter hereof and express no opinion and provide no assurance as to compliance with any federal or state securities law, rule or regulation.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares, when sold and issued against payment therefore in accordance with the Registration Statement and the Prospectus, will be validly issued, fully paid and non-assessable.

We consent to the reference to our firm under the caption “Legal Matters” in the Prospectus included in the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement.

Sincerely,
