The Company received aggregate proceeds of $162.6 million from the IPO, net of underwriters’ discounts and commissions, and before deducting offering costs of approximately $4.9 million. Upon the closing of the IPO, all shares of the Company’s outstanding redeemable convertible and convertible preferred stock automatically converted into 46,079,623 shares of common stock. Additionally, an outstanding warrant which became exercisable upon the closing of the IPO was exercised to purchase 485,985 shares of common stock. 7

Accordingly, certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the financial information included in our Annual Report on Form 10-K for 2018 filed with the SEC on March 8, 2019 (“2018 Form 10-K”). STATEMENTS

The consolidated financial statements include our results of operations and those of our wholly-owned subsidiaries and reflect all adjustments which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. All intercompany transactions and balances have been eliminated in consolidation. (UNAUDITED)

Certain previously reported amounts presented in this Quarterly Report on Form 10-Q (“Form 10-Q”) may be reclassified to conform to current-period presentation. Events occurring subsequent to the date of our consolidated balance sheet were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-Q with the SEC.

~~Use~~TABLE ofOF ~~Estimates~~ CONTENTS

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates, and such differences may be material to the consolidated financial statements. For additional information about our use of estimates refer to “Critical Accounting Policies” included under management’s discussion and analysis in our 2018 Form 10-K.

~~(UNAUDITED)~~ CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

~~Effective January 1, 2019, the Company adopted the requirements of Accounting Standards Update~~ (~~“ASU”~~UNAUDITED) No. 2016-02, Leases (Topic 842) (“ASC 842”) on a modified retrospective transition approach as discussed in detail in Note 2. All amounts and disclosures set forth in this Form 10-Q have been updated to comply with ASC 842.

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits an “emerging growth company” such as the Company, to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. The Company has irrevocably elected to “opt out” of this provision and, as a result, the Company will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. For a complete discussion of our significant accounting policies refer to Note 2 to the consolidated financial statements in our 2018 Form 10-K.

~~Recently issued accounting pronouncements:~~ Overview

Standard	Description	Date of Adoption	Effects on the financial statements or other significant matters
ASU 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software	The standard was issued in order to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is considered a service contract. Under this guidance, implementation costs for a CCA should be evaluated for capitalization using the same approach as implementation costs associated with internal-use software. Generally costs incurred to configure/customize the hosted software are capitalizable, however, data conversion and training costs are expensed as incurred consistent with internal-use software guidance. The amortization period is over the non-cancelable term and any reasonable certain renewals are expensed to the same line item in which fees paid to the vendor are recognized (i.e., not included in amortization expense).	January 1, 2020, early adoption permitted	We are currently assessing the impact of the standard on our consolidated financial statements.
ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	The standard requires immediate recognition of expected credit losses for financial assets carried at amortized cost, including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets, held at the reporting date to be measured based on historical experience, current conditions and reasonable supportable forecasts. Credit losses on available-for-sale securities will be recorded as an allowance versus a write-down of the amortized cost basis of the security and will allow for a reversal of impairment loss when the credit of the issuer improves.	January 1, 2020, early adoption permitted	We are currently assessing the impact of the standard on our consolidated financial statements.

Accordingly, all share and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this reverse stock split and adjustment of the preferred stock conversion ratios.

~~CONDENSED~~Initial ~~NOTES~~Public ~~TO THE CONSOLIDATED FINANCIAL STATEMENTS~~ Offering

On May 8, 2018, the Company closed its initial public offering (~~UNAUDITED~~“IPO”) , in which it issued and sold 9,200,000 shares of common stock inclusive of the underwriters’ option to purchase additional shares that was exercised in full. The price to the public was $19.00 per share. The Company received aggregate proceeds of $162.6 million from the IPO, net of underwriters’ discounts and commissions, and before deducting offering costs of approximately $4.9 million. Upon the closing of the IPO, all shares of the Company’s outstanding redeemable convertible and convertible preferred stock automatically converted into 46,079,623 shares of common stock. Additionally, an outstanding warrant which became exercisable upon the closing of the IPO was exercised to purchase 485,985 shares of common stock.

ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	The standard simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The ASU requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying value exceeds the fair value of the reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss.	January 1, 2020, early adoption permitted	We are currently evaluating the impacts of early adoption and will apply this standard prospectively, as applicable.
ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement	The standard eliminates, amends and adds disclosure requirements for fair value measurements. Eliminated disclosures include: amount of and reasons for transfers between levels 1 and 2, policy on timing of transfers, valuation processes for level 3. Removal of the requirement to disclose future changes in FV inputs. Relevant amended disclosures include no longer requiring full level 3 rollforward but rather disclosure of transfers in/out and purchases/ issuances. New disclosures include changes in OCI on level 3 assets/ liabilities and disclosure of range and weighted average of significant unobservable inputs for level 3.	January 1, 2020, early adoption permitted	We are in the process of evaluating the changes required by the new provisions. We expect this to be minimal as we do not have any level 3 inputs.

~~NOTE 3. CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS~~ (UNAUDITED)

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company’s cash equivalents consist of highly liquid investments in money market funds.

~~The~~NOTE ~~Company considers all high quality investments purchased with original maturities at the date of purchase greater than three months to be short-term investments~~2. ~~Investments~~NEW ~~are~~ACCOUNTING available to be used for current operations and are, therefore, classified as current assets even though maturities may extend beyond one year. Short-term investments are classified as available-for-sale and are, therefore, recorded at fair value on the consolidated balance sheet, with any unrealized gains and losses reported in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ equity in the Company’s consolidated balance sheets, until realized. The Company uses the specific identification method to compute gains and losses on the investments. The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion is included as a component of interest income in the consolidated statement of operations. PRONOUNCEMENTS

NOTE 3. CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

14 The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company’s cash equivalents consist of highly liquid investments in money market funds.

~~Table~~The Company considers all high quality investments purchased with original maturities at the date of ~~Contents~~ purchase greater than three months to be short-term investments. Investments are available to be used for current operations and are, therefore, classified as current assets even though maturities may extend beyond one year. Short-term investments are classified as available-for-sale and are, therefore, recorded at fair value on the consolidated balance sheet, with any unrealized gains and losses reported in accumulated other comprehensive income (loss), which is reflected as a separate component of stockholders’ equity in the Company’s consolidated balance sheets, until realized. The Company uses the specific identification method to compute gains and losses on the investments. The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion is included as a component of interest income in the consolidated statement of operations.

~~CARBON~~The ~~BLACK~~ following tables present the amortized cost, fair value and associated unrealized gains and losses of cash equivalents and short-term investments as of the periods presented:

~~7. LEASES~~

We lease various office space and data centers under non-cancellable operating leases. Our leases have remaining lease terms ranging from 1 year to 5 years, some of which include extension options of up to 5 years and termination options within 3 years. The exercise of these lease extension and termination options are at our sole discretion. 13

~~Right-of-use~~CARBON (“ROU”) assets represent the Company’s right to use leased assets over the term of the lease. Lease liabilities represent the Company’s contractual obligation to make lease payments over the lease term. We determine if an arrangement is a lease at inception. Right-of-use assets and lease liabilities are initially measured at the lease commencement date based on the present value of the lease payments over the lease term, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our incremental borrowing rate. We determine our incremental borrowing rate based on the rate of interest that we would have to pay to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Our lease right-of-use assets also include any unamortized initial direct costs plus any prepayments less any unamortized lease incentives received. BLACK

~~Leases~~CONDENSED ~~with~~NOTES anTO ~~initial~~THE ~~term~~CONSOLIDATED ofFINANCIAL 12 months or less are classified as short-term leases and are not recorded on the balance sheet. Lease expenses relating to our short-term leases are recognized on a straight-line basis over the lease term. For lease agreements we entered into or reassessed after the adoption of Topic 842, we combine lease and non-lease components as a single lease component. Non-lease components primarily consist of payments for maintenance and utilities. STATEMENTS

Our lease agreements do not contain any material residual value guarantees, material restrictive covenants or variable lease payments based on an index or rate. We currently sublease one of our office spaces to a third party. (UNAUDITED)

~~The~~Right-of-use ~~following~~(“ROU”) ~~table~~assets ~~summarizes~~represent the Company’s right to use leased assets over the term of the lease. Lease liabilities represent the Company’s contractual obligation to make lease payments over the lease term. We determine if an arrangement is a lease at inception. Right-of-use assets and lease liabilities are initially measured at the lease commencement date based on the present value of the lease payments over the lease term, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our ~~common~~incremental ~~stock~~borrowing ~~option~~rate. ~~activity~~We ~~for~~determine our incremental borrowing rate based on the ~~three~~rate ~~months~~of ~~ended~~interest ~~March~~that 31we would have to pay to borrow on a collateralized basis over a similar term, ~~2019:~~ an amount equal to the lease payments in a similar economic environment. Our lease right-of-use assets also include any unamortized initial direct costs plus any prepayments less any unamortized lease incentives received.

Leases with an initial term of 12 months or less are classified as short-term leases and are not recorded on the balance sheet. Lease expenses relating to our short-term leases are recognized on a straight-line basis over the lease term. For lease agreements we entered into or reassessed after the adoption of Topic 842, we combine lease and non-lease components as a single lease component. Non-lease components primarily consist of payments for maintenance and utilities.

Transaction price allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and backlog. The Company defines backlog as contractually committed orders for subscriptions and support services for which the associated revenue has not been recognized and the customer has not been invoiced. As of March 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $183.2 million in deferred revenue and $40.0 million in backlog.

Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by diluted weighted-average shares outstanding, including potentially dilutive securities, unless anti-dilutive.

As ~~the~~ ~~company~~ was in a loss for all periods presented, basic net loss per share is the same as dilutive net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. The following table presents the calculation for basic and diluted net loss per share attributable to common stockholders for the dates indicated:

Subject to any plan limitations, the 2018 ESPP allows eligible employees to contribute through payroll deductions, up to 10% of their base compensation during the offering period, for the purchase of the Company’s common stock at a discounted price per share.

~~FORWARD-LOOKING~~Unless ~~STATEMENTS~~ the participating employee has previously withdrawn from the offering, their accumulated payroll deductions will be used to purchase shares of common stock on the last business day of the offering period at a price equal to 85% of the fair market value of the common stock on the first business day or the last business day of the offering period, whichever is lower. ESPP employee payroll contributions are included within accrued expenses in the consolidated balance sheet and are reclassified to stockholders’ equity on the purchase date.

~~Key~~Major ~~Factors~~products ~~Affecting~~and ~~Our~~services ~~Performance~~

~~Our historical financial performance has been, and we expect our financial performance in the future to be, primarily driven by the following factors:~~

Market Adoption

(In thousands)	2019		2018		2019		2018
Subscription and support revenue	$	34,187	$	32,648	$	67,928	$	64,743

We believe our future success will depend, in large part, on the market for next-generation endpoint security. Because network-centric security is no longer adequate, organizations must focus on securing the endpoint. However, while organizations have made significant investments in upgrading to advanced network security solutions, the majority of endpoint security technology in use today relies on multiple agents and uses the same ineffective, traditional signature-based antivirus software. As a result, organizations are increasingly shifting their security budgets toward next-generation endpoint security solutions. We believe that we are well positioned as a market leader to capitalize on this investment cycle and that our ability to address the full lifecycle of a cyber attack will help to drive our market adoption. Additionally, the number of security professionals has not kept pace with total demand. As the number of threats multiplies, legacy solutions either miss threats or produce more alerts than security teams are able to process and investigate. Organizations are increasingly turning to next-generation solutions, advanced analytics and automation tools to empower their security professionals to increase their efficiency and focus on the highest value cyber security tasks, thereby reducing the need for additional security headcount. Organizations are also addressing the talent gap by relying more on security-focused VARs and trusted partners to augment their internal teams of security experts.

We expect this trend to continue in future periods as we focus on adding new customers and renewing existing customers through our channel partners. We are focused on continuing to grow our customer ~~base.~~for We have continuously enhanced our endpoint security platform and product offerings, and we have expanded both our domestic and international sales force to drive new customer acquisition. However, our ability to continue to grow our customer base is dependent on a number of factors, including our ability to compete within the ~~increasingly~~periods ~~competitive markets in which we participate.~~ indicated:

~~Maintain Strong Retention Rates~~

An important component of our revenue growth strategy is to have our existing customers renew their agreements with us. To assess our performance against this objective, we monitor the retention rate of our existing customers. We calculate retention rate by comparing the annual recurring subscription and support revenue from our customers at the beginning of a measurement period. We divide the ending annual recurring revenue by the beginning annual recurring revenue to arrive at our retention rate metric. We exclude the impact of any add-on purchases from these customers during the measurement period; accordingly, our retention rate cannot exceed 100%. In addition, the metric reflects the loss of customers who elected not to renew contracts expiring during the measurement period and customers who elected to reduce their contract spend during the measurement period. Our retention rate was approximately 87% for the three months ended March 31, 2019.

~~Increase Sales to Existing Customers~~

Our current customer base provides us with a significant opportunity to drive incremental sales. Our extensible platform allows us to develop new solutions rapidly and at a lower cost over time. As we develop and deploy additional security offerings on the CB Predictive Security Cloud platform, we see significant additional opportunity to cross-sell these offerings as customers benefit by addressing multiple security requirements through a single platform. Our ability to increase sales to existing customers will depend on a number of factors, including customers’ satisfaction or dissatisfaction with our solutions, our ability to develop new products, pricing, economic conditions or overall reductions in our customers’ spending levels.

~~Invest in Growth~~

We will continue to focus on long-term revenue growth. We believe that our market opportunity is large and we will continue to invest significantly in research and development to enhance our technology platform and product functionality. We also expect to continue to invest in sales and marketing to grow our customer base, both domestically and internationally. In addition to our ongoing investment in research and development, we may also pursue acquisitions of businesses, technologies and assets that complement and expand the functionality of

We use billings as one factor to evaluate our business because billings is an indicator of current period sales activity and provides visibility into corresponding future revenue growth due to our subscription-based revenue model. However, it is important to note that billings, in any period, may be impacted by the timing of customer renewals, including early renewals, and customers’ preferences for multi-year upfront or annual billing terms, which could favorably or unfavorably impact year-over-year comparisons. While we believe that billings is somewhat useful in evaluating our business, billings is a non-GAAP financial measure that has limitations as an analytical tool, and billings should not be considered as an alternative to, or substitute for, total revenue recognized in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate billings differently or not at all, which reduces the usefulness of billings as a tool for comparison. We recommend that you review the reconciliation of billings to total revenue, the most directly comparable GAAP financial measure, provided below, and that you not rely on billings or any single financial measure to evaluate our business. 21

We use recurring revenue as one factor to evaluate our business because we believe that recurring revenue provides visibility into the revenue expected to be recognized in the current and future periods. Accordingly, we believe that recurring revenue provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management. While we believe that recurring revenue is useful in evaluating our business, recurring revenue is a non-GAAP financial measure that has limitations as an analytical tool, and recurring revenue should not be considered as an alternative to, or substitute for, subscription, license and support revenue recognized in accordance with GAAP.

30 Organizations globally are re-platforming their IT operations by investing in cloud computing and workforce mobility, which has resulted in enterprise environments that are more open, interconnected, and vulnerable to cyber attacks. Today, an increasingly mobile workforce and the explosion of enterprise data and applications in the cloud have expanded the attack surface beyond the traditional network perimeter. In response, attackers have adapted their methods and tools to directly target the endpoint. In short, the endpoint is the new perimeter.

~~Table~~Endpoints are the primary focus of ~~Contents~~ attacks because they store valuable data that attackers seek to steal; perform critical operations that attackers seek to disrupt; and are the interface where attackers can target humans through email, social engineering and other tactics. Endpoints are the physical and virtual locations where sensitive data resides and include desktops, laptops, servers, virtual machines, cloud workloads (services running on cloud servers), containers, fixed-function devices such as ATMs, point of sale systems, and control and data systems for power plants and other industrial assets.

~~CARBON~~Our ~~BLACK~~ approach to solving these endpoint security challenges focuses on leveraging our big data and our security analytics platform in the cloud (the PSC) to better detect and prevent the behaviors and specific techniques used by attackers. Based on our experience and investment in solutions designed to address the full endpoint security lifecycle, we have developed a highly differentiated technology approach with four main pillars: (1) unfiltered data collection, (2) proprietary data shaping technology, (3) streaming analytics, and (4) extensible open architecture.

Recurring revenue, a non-GAAP financial measure, represented 94% of our total revenue for both the three and six months ended June 30, 2019, respectively. Annual recurring revenue, or ARR, was $237.6 million and $195.5 million as of June 30, 2019 and 2018, respectively.
