Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under Part I, Item 1A, “Risk Factors” and elsewhere in this Annual Report on Form 10-K.

For the discussion of our financial condition and results of operations for the year ended December 31, 2020 compared to the year ended December 31, 2019, please refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 15, 2021.

We are a commercial-stage medical technology company that provides a minimally invasive treatment for patients with severe emphysema, a form of chronic obstructive pulmonary disease (“COPD”).

Our solution, which is comprised of the Zephyr Endobronchial Valve (“Zephyr Valve”), the Chartis Pulmonary Assessment System (“Chartis System”) and the StratX Lung Analysis Platform (“StratX Platform”), is designed to treat severe emphysema patients who, despite medical management, are still profoundly symptomatic and either do not want or are ineligible for surgical approaches.

We estimate our solution currently addresses approximately 500,000 patients in the United States and 700,000 patients in select international markets, which represents a global market opportunity of approximately $12 billion.

We have a compelling body of clinical evidence with over 100 scientific articles published regarding the clinical benefits of Zephyr Valves, including in The New England Journal of Medicine , The Lancet and the American Journal of Respiratory and Critical Care Medicine .

Multiple randomized controlled clinical trials have demonstrated that patients selected with the Chartis System and successfully treated with Zephyr Valves have shown statistically and clinically significant improvements in lung function, exercise capacity and quality of life compared to medical management alone.

In June 2018, we received pre-market approval (“PMA”) by the U.S.

Impact of the COVID-19 Pandemic

The COVID-19 pandemic has resulted in public health responses including travel bans, social distancing requirements, quarantines, stay-at-home orders and other significant measures, which have delayed clinical trials and FDA operations and adversely impacted the number of procedures performed using our products.

In the markets in which we operate, elective, specialty and other procedures and appointments have been suspended or canceled to avoid non-essential patient exposure to medical environments and potential infection with COVID-19 and to focus limited resources and personnel capacity toward the treatment of COVID-19 patients.

As a result, we have experienced a material adverse impact on our business, financial condition and results of operations from a decrease and delay of procedures involving our products.

The COVID-19-driven impact on procedure volumes, which began in 2020, extended into the first quarter of 2021.

Beginning in March 2021, we observed indicators of recovery in our U.S.

markets which continued through the second quarter.

During the third quarter of 2021, procedure volumes were adversely impacted by the Delta variant of COVID-19 in certain regions of the U.S.

During the fourth quarter of 2021, sales increased in regions of the U.S.

less affected by COVID-19, which were partially offset by decreased sales in U.S.

regions significantly impacted by the Delta and Omicron variants of COVID-19.

In international markets, our business faced continued pressure in the fourth quarter of 2021 as a result of the COVID-19 surge that led to lockdowns across a number of markets in Europe.

We may continue to see regional variations in procedure volumes in our U.S.

and international markets

from the COVID-19 pandemic and its variants.

The COVID-19 pandemic has delayed clinical trials and FDA operations and adversely impacted the number of procedures performed using our products.

As a result, the COVID-19 pandemic and the measures taken by many countries in response have materially adversely affected, and could in the future materially adversely affect, our business, financial condition and results of operations, as well as the price of our common stock, from a decrease and delay of procedures involving our products.

While the Company has seen a recovery in procedure volumes in the U.S.

and some international markets, other international markets continue to be hampered by a slower recovery.

We are encouraged for the longer term, and we believe the following key indicators are contributing to the stabilization of our business:

• continued opening of new accounts;

• strong physician participation in virtual trainings;

• a strong patient pipeline evidenced by an increase in StratX report activity, a rebound in patient calls into hospitals inquiring about our procedure, and a resumption of patient calls to our reimbursement support service;

• hospitals and centers accepting patients for elective procedures.

In response to the COVID-19 pandemic, we implemented a variety of measures intended to help us manage through the impact of the pandemic and position us to resume operations quickly and efficiently as restrictions, recommendations, and best practices evolve.

These measures have included, and continue to include:

• establishing safety protocols, facility enhancements, and work-from-home strategies to protect our employees;

• ensuring that our manufacturing and supply chain operations remain intact and operational, and building over four months of inventory;

• keeping our workforce intact and continuing to build our team, including expansion of our U.S.

• continuing to focus on new account openings and implementing virtual physician and sales force training programs;

• accelerating our physician education programs and direct-to-patient marketing efforts through social media or other virtual forums;

• increasing our capital base by $201.4 million through our IPO in October 2020;

• continuing to invest in research and development activities in order to advance our AeriSeal clinical programs.

• strong physician participation in trainings;

• a strong patient pipeline evidenced by StratX report activity, patient calls into hospitals inquiring about our procedure, and patient calls to our reimbursement support service;

• a resumption of elective procedures at hospitals and centers.

Despite signs of recovery of our business, we cannot be certain that any recovery will be sustained, or that a further resurgence of COVID-19 or variants of the virus will not occur.

The measures adopted in response to, and challenges resulting from, the COVID-19 pandemic may continue to adversely affect our employees, including our sales force, hospitals, physicians, patients, communities and business operations, and may continue to contribute to significant volatility and negative pressure on the U.S.

and world economy and financial markets.

Further, we cannot assure you that our recent volume of Zephyr Valves sold are indicative of future results.

Limited provider and hospital capacity has had a material adverse effect on our business, financial condition and results of operations and may continue to materially adversely affect us even as the pandemic subsides.

The extent to which the COVID-19 pandemic impacts our business, financial condition and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity and spread of COVID-19 and variant strains, governmental and societal response to contain and treat COVID-19 and variant strains, and the availability and distribution of vaccines and public acceptance of vaccines, among others.

Our consolidated financial statements reflect judgments and estimates that could change in the future as a result of the COVID-19 pandemic.

For more information regarding these risks and potential impacts, please refer to Part I, Item 1A, “Risk Factors.”

The extent of the impact of COVID-19, including the macroeconomic conditions, on our future operational and financial performance will depend on certain developments, which are highly uncertain and cannot be predicted,

including impact on employees, clinical trials and procedure volumes, new information which may emerge concerning the severity and spread of COVID-19 and variant strains, governmental and societal response to contain and treat COVID-19 and variant strains, and the availability and distribution of vaccines and public acceptance of vaccines, among others.

Oxford Finance Loan

From August 2014 until February 2020, the Company was party to a Loan and Security Agreement with Oxford Finance LLC, which provided the ability to borrow up to $20.0 million in term loans (“Oxford Finance Loan”).

In 2014, the Company borrowed $15.0 million.

The term loan bore interest at 8.96% and had a five-year term.

The first 36 months were interest only payments followed by 24 months of equal payments of principal and interest.

A final payment of 8.5% of the term loan amount was due at maturity and was being accreted using the effective interest rate method.

The term loan was collateralized by assets, including cash and cash equivalents, accounts receivable and property and equipment.

The Oxford Finance Loan was subsequently amended in 2017 and 2018 to extend the interest only period and to extend the maturity date to July 1, 2020, and at the Company’s option, further extend the maturity date to May 1, 2021.

In 2019, the Company elected to extend the maturity date to May 2021.

In connection with the original agreement in August 2014, the Company also entered into the Success Fee Agreement.

LLC, the amount of which would be based on actual borrowings, up to $20.0 million.

The availability of Tranche B and Tranche C is further conditioned upon the joining of Pulmonx International Sàrl to the CIBC Agreement and the execution by Pulmonx International Sàrl of Swiss-law collateral documentation in favor of CIBC.

The CIBC Loan originally had a five-year term maturing on February 20, 2025, which included 24 months of interest only payments followed by 36 months of equal payments of principal and interest.

The interest only period can be extended to 36 months if the Company achieves three-month trailing revenue of at least $20.0 million as of February 20, 2022.

As of December 31, 2021, the CIBC Loan had an annual effective interest rate of 4.71% per year.

The financial covenants in the CIBC Agreement require that, when the cash and cash equivalents of the Company is less than $100.0 million, the Company have revenue for the trailing three-month period ending on the last day of each fiscal quarter of not less than 80.0% of the revenue for the trailing three-month period, as set forth in the annual projections delivered to the CIBC.

Further, the Company is required to maintain unrestricted cash in an aggregate amount equal to or greater than the Adjusted EBITDA loss as defined in the CIBC Agreement for the four-month period ending on any date of determination.

As of December 31, 2021, the Company was in compliance with all covenants contained in CIBC Agreement.

The Company paid $0.4 million fees to the lender and third parties, which is reflected as a discount on the CIBC Loan and is being accreted over the life of the term loan using the effective interest method.

During the year ended December 31, 2021 and December 31, 2020, the Company recorded interest expense related to debt discount and debt issuance costs of CIBC Loan of $0.1 million and $0.1 million, respectively.

On October 31, 2022, we entered into a Third Amendment to the Amended and Restated CIBC Agreement (the “Third Amendment”), which, among other things, extended the maturity date to October 31, 2027;

provided a commitment for a new $20.0 million tranche of term loans that may be drawn at the Company’s option through October 31, 2023, subject to the satisfaction of certain conditions;

and provided for a new interest only period of 24 months from the signing date of the Third Amendment, with the possibility of an additional extension of such interest only period of up to 12 months, subject to satisfaction of certain conditions.

The loans provided under the Amended and Restated CIBC Agreement bear interest at a floating rate equal to 1.0% above the Wall Street Journal Prime Rate at any time.

The loan is collateralized by substantially all of our assets, including cash and cash equivalents, accounts receivable, intellectual property and equipment.

We may prepay the loans without penalty.

If we borrow any of the $20.0 million tranche made available under the Third Amendment, we may prepay the loans, subject to certain conditions, including a prepayment fee equal to 2.0% of the principal amount repaid during the first year after the effective date of the Third Amendment or 1.0% of the principal amount prepaid during the second year after the effective date of the Third Amendment.

The Amended and Restated CIBC Agreement contains financial covenants that require the Company to maintain minimum cash and minimum revenue amounts, and the Amended and Restated CIBC Agreement contains other customary restrictive covenants, representations and warranties, events of default and other customary terms and conditions.

We paid $0.4 million fees to the lender and third parties which is reflected as a discount on the loans provided under the Amended and Restated CIBC Agreement and is being accreted over the life of the loan using the effective interest method.

During the years ended December 31, 2022 and December 31, 2021, we recorded interest expense related to debt discount and debt issuance costs of CIBC Loan of $0.1 million and $0.1 million, respectively.

Interest expense on the CIBC Loan amounted $1.1 million and $0.8 million during the year ended December 31, 2022 and December 31, 2021, respectively.

In April 2020, the Company entered into a Note Purchase Agreement and Convertible Promissory Notes (collectively the “2020 Notes Agreement”) with certain investors (the “Lenders”) to issue convertible promissory notes (the “2020 Notes”) for a maximum aggregate amount of $66.0 million.

In April 2020, the Company received $33.0 million in gross proceeds from issuance of the 2020 Notes.

Upon meeting customary closing conditions, the Company can draw up to an additional $33.0 million, provided that any such draw be for no less than $5.0 million on or prior to April 17, 2022.

All unpaid interest and principal will be due and payable upon request of the majority of Lenders (“Majority Holders”) on or after the earlier of April 17, 2022 or an event of default.

The 2020 Notes accrue interest at a rate equal to 2.0% above the Wall Street Journal Prime Rate.

The Company may prepay the 2020 Notes prior to April 17, 2022 only with the consent of the Majority Holders.

The 2020 Notes included embedded derivatives that were required to be bifurcated from the 2020 Notes and accounted for separately as a single, compound embedded derivative instrument under ASC 815, Derivatives (“2020 Notes derivative liability”).

The Company determined that a share settled redemption in the case of a financing or an IPO as described in the 2020 Notes represented an embedded derivative that was not clearly and closely related to the debt host and had accounted for these settlement alternatives as separate embedded derivative liability.

The fair value of the 2020 Notes derivative liability of $3.9 million was recorded on the issuance date of the 2020 Notes

resulting in a debt discount, which was reported as a direct deduction from the face amount of the 2020 Notes.

The 2020 Notes derivative liability was remeasured to its fair value at the end of each reporting period and any change in fair value is recognized in other income (expense), net in the statements of operations and comprehensive loss (Note 4).

The change in fair value of $3.9 million during the year ended December 31, 2020 was recorded as a component of other income (expense), net in the consolidated statements of operations and comprehensive loss.

Upon the closing of the IPO in October 2020, the $33.0 million aggregate outstanding principal amount and $0.8 million accrued interest of the 2020 Notes converted into 2,561,484 shares of common stock pursuant to the Qualified IPO conversion at the $13.20 per share fixed price.

The Company determined that the 2020 Notes derivative liability had no value upon the closing of the IPO, because value of the notes with and without such derivative was the same.

The Company incurred debt issuance costs of $0.1 million in connection with the 2020 Notes Agreement, which were reported on the balance sheet as a direct deduction from the face amount of the 2020 Notes.

During the year ended December 31, 2020, the Company recorded interest expense of $1.6 million on the 2020 Notes, consisting of $0.8 million of contractual interest expense and $0.8 million amortization of debt discount and debt issuance costs.

Before the conversion upon the IPO, the 2020 Notes had an annual effective interest rate of 12.33% per year.

At December 31, 2021, the Company retained the ability to draw up to an additional $33.0 million under the 2020 Notes Agreement until the maturity date in April 2022.

The Company’s obligations with respect to the 2020 Notes are unsecured and subordinated to its obligations with respect to the CIBC Loan.

The 2020 Notes have customary events of default.

Preferred Stock

We record all shares of preferred stock at their respective fair values on the dates of issuance, net of issuance costs.

Our preferred stock is recorded outside of permanent equity because while it is not mandatorily redeemable, in certain events considered not solely within our control, such as a merger, acquisition or sale of all or substantially all of our assets, each of which we refer to as a deemed liquidation event, our preferred stock will become redeemable at the option of the holders of at least a majority of the then outstanding such shares.

We have not adjusted the carrying values of the preferred stock to its liquidation preference because a deemed liquidation event obligating us to pay the liquidation preferences to holders of shares of preferred stock is not probable.

Subsequent adjustments to the carrying values to the liquidation preferences will be made only when it becomes probable that such a deemed liquidation event will occur.

Derivative Instruments

In connection with the Oxford Agreement, we entered into the Success Fee Agreement.

In the event of a Liquidity Event, before the termination of the agreement on August 28, 2021, we are required to pay up to $2.5 million to Oxford Finance LLC.

The Success Fee is equal to 6.25% of the term loan if the Liquidity Event occurs within 18 months of August 28, 2014, 8.75% if the Liquidity Event occurs after 18 months and within 3 years of August 28, 2014, and 12.50% if the Liquidity Event occurs after the third anniversary of August 28, 2014.

As of December 31, 2019, the maximum amount of Success Fee subject to a potential payout was $1.9 million.

This agreement has been identified as a freestanding derivative under ASC 815, Derivatives (“Success Fee”) and is remeasured to its fair value at the end of each reporting period and any change in fair value is recognized as change in other income (expense), net in the statements of operations and comprehensive loss (see Note 4 to our consolidated financial statements).

We valued the Success Fee derivative liability based on the Success Fee amount of $1.9 million and the probability and estimated timing of a Liquidity Event.

On October 5, 2020, in connection with the IPO, we paid $1.9 million pursuant to the Success Fee Agreement to Oxford Finance LLC.

The 2020 Notes include embedded derivatives that are required to be bifurcated from the 2020 Notes and accounted for separately as a single, compound embedded derivative instrument under ASC 815, Derivatives (2020 Notes derivative liability).

We determined that the share settled redemption in the case of a financing or an IPO represents an embedded derivative that is not clearly and closely related to the debt host and have accounted for these

settlement alternatives as separate embedded derivative liability.

The fair value of the 2020 derivative liability of $3.9 million was recorded on the issuance date of the 2020 Notes resulting in a debt discount, which is reported as a direct deduction from the face amount of the 2020 Notes.

The 2020 derivative liability is remeasured to its fair value at the end of each reporting period and any change in fair value is recognized in other income (expense), net in the statements of operations and comprehensive loss.

We valued the 2020 Notes derivative liability using the “with and without” methodology.

The “with and without” methodology involves valuing the convertible note on an as is basis and then valuing the 2020 Notes without each individual embedded derivative.

The difference between the value of the 2020 Notes with the embedded derivatives and the value without each individual embedded derivative equals the fair value of that embedded derivative.

We used a Monte Carlo Simulation (“MCS”) to value the embedded derivatives.

The first step of each simulation was to forecast our Series G-1 preferred stock price through the expiration of the 2020 Notes.

In order to estimate the future share price of the Series G-1 preferred stock, we applied a “random walk” model based upon a Geometric Brownian Motion process with a constant drift.

The fair value of the 2020 Notes derivative liability was determined using the following assumptions:

Risk-free interest rate 0.2 %

Current Series G-1 convertible preferred stock value per share $ 0.84

Series G-1 convertible preferred stock volatility 34.4 %

Upon the closing of the IPO in October 2020, the 2020 Notes converted pursuant to a qualified initial public offering.

As a result, we concluded that the 2020 Notes derivative had no value upon the closing of the IPO, because value of the notes with and without such derivative was the same.

Common Stock Valuation

Prior to the Company’s IPO, the estimated fair value of the common stock underlying our stock options and stock awards was determined at each grant date by our board of directors, with input from management.

All options to purchase shares of our common stock are intended to be exercisable at a price per share not less than the per-share fair value of our common stock underlying those options on the date of grant.

In the absence of a public trading market for our common stock, on each grant date, we develop an estimate of the fair value of our common stock based on the information known to us on the date of grant, upon a review of any recent events and their potential impact on the estimated fair value per share of the common stock, and in part on contemporaneous input from an independent third-party valuation firm.

Our valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation (Practice Aid).

The assumptions used to determine the estimated fair value of our common stock are based on numerous objective and subjective factors, combined with management judgment, including:

• external market conditions affecting the pharmaceutical and medical devices industry and trends within the industry;

• our stage of development and business strategy;

• the rights, preferences and privileges of our convertible preferred stock relative to those of our common stock;

• the prices at which we sold shares of our convertible preferred stock;

• our financial condition and operating results, including our levels of available capital resources;

• the progress of our research and development efforts;

• equity market conditions affecting comparable public companies;

• general U.S.

market conditions and the lack of marketability of our common stock.

For our valuations performed in August 2019, we applied the market approach outlined in the Practice Aid to determine our enterprise value.

Specifically, we used the guideline public company analysis, which relies on an analysis of publicly traded companies similar in industry or business model to us and uses these guideline companies to develop relevant market multiples and ratios.

These multiples and ratios were then applied to our corresponding financial metrics.

For our valuations performed in November 2019 and April 2020, we applied a weighted combination of the market approach and the income approach outlined in the Practice Aid to determine our enterprise value.

Under the market approach, we used the guideline public company analysis, guideline transactions analysis and an analysis based on a recent acquisition offer.

For the guideline public company and guideline transactions analysis, we identified a group of comparable public companies and recent transactions within our industry.

For the comparable companies, we estimated market multiples and ratios.

These multiples and ratios were then applied to our corresponding financial metrics.

When selecting comparable companies, consideration was given to industry similarity, their specific products offered, financial data availability and capital structure.

The income approach incorporates the use of a discounted cash flow model in which our estimated future cash flows and our residual value beyond the forecast period are discounted using an appropriately risk-adjusted weighted average cost of capital.

Our forecasts used in the discounted cash flow model are based in part on strategic plans and represent our estimates based on current and forecasted business and market conditions.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date.

In accordance with the Practice Aid, we considered the following methods:

• Option Pricing Method.

Under the option pricing method (OPM), shares are valued by creating a series of call options with exercise prices based on the liquidation preferences and conversion terms of each equity class.

The estimated fair values of the preferred and common stock are inferred by analyzing these options.

• Probability-Weighted Expected Return Method.

The probability-weighted expected return method is a scenario-based analysis that estimates value per share based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to us, as well as the economic and control rights of each share class.

We determined that the OPM method was the most appropriate method for allocating our enterprise value to determine the estimated fair value of our common stock.

In determining the estimated fair value of our common stock, our board of directors also considered the fact that our stockholders could not freely trade our common stock in the public markets.

Accordingly, we applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity.

The estimated fair value of our common stock at each grant date reflected a non-marketability discount partially based on the anticipated likelihood and timing of a future liquidity event.

As of December 31, 2022, there was $41.6 million of unrecognized compensation costs related to non-vested common stock options and restricted stock units, expected to be recognized over a weighted-average period of 2.73 years.

Subsequent to the Company’s IPO, the fair value of the Company’s common stock is determined based on its closing market price.

Subsequent to our IPO, the fair value of our common stock is determined based on our closing market price.
