“In the third quarter we made significant progress toward delivering the benefits of nano-PFA to patients and providers around the world. Our clinical work with each of our three devices continues to suggest that our differentiated nano-PFA technology has the potential to improve treatments for several disease states by eradicating cells in a better way than currently available modalities,” said Burke T. Barrett, President and Chief Executive Officer of Pulse Biosciences. “The work we have done to date positions us to begin pivotal clinical trials in the U.S. for each device next year and to also share select European trial data at medical conferences in the future. We are building our team and the infrastructure required to support our clinical and regulatory initiatives and anticipated growth, starting with commercial use of the nsPFA Percutaneous Electrode System in the coming quarters.”

Third Quarter 2024 Financial Results

Total GAAP costs and expenses, representing research and development and general and administrative expenses, for the three months ended September 30, 2024, were $13.7 million, an increase of $2.4 million, compared to $11.3 million in the prior year period. The increase was primarily driven by stock-based compensation and other compensation and administrative expenses to support the expanding organization and the advancement of our nano-PFA devices. Non-GAAP costs and expenses for the three months ended September 30, 2024, were $10.4 million, an increase of $1.2 million compared to $9.2 million in the prior year period.

GAAP net loss for the three months ended September 30, 2024 was ($12.7) million compared to ($10.6) million for the three months ended September 30, 2023. Non-GAAP net loss for the three months ended September 30, 2024 was ($9.4) million compared to ($8.5) million for the three months ended September 30, 2023.

Cash and cash equivalents totaled $79.0 million as of September 30, 2024. The cash balance as of September 30, 2024 includes $60 million in gross proceeds received from the rights offering that closed in July of 2024. The Company has the potential to raise an additional up to $66 million through the exercise of warrants associated with this rights offering. Each warrant is exercisable for $11 per share, which equals 110% of the subscription price for the Units. Warrants are exercisable immediately. Half of the warrants are redeemable by the Company if the Company’s stock trading price exceeds $16.50 for twenty consecutive trading days and the other half of the warrants are redeemable by the Company if its stock trading price exceeds $22.00 for twenty consecutive trading days. Holders of the warrants have the right to exercise them at any time until they are redeemed or expire.

Cash used in the third quarter of 2024 was $8.5 million, excluding financing activity, compared to $8.7 million used in the second quarter of 2024 and $8.7 million in the third quarter of 2023.

Reconciliations of GAAP to non-GAAP cost and expenses and net loss have been provided in the tables following the financial statements in this press release. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures.”

Non-GAAP Financial Measures

In this press release, in order to supplement the Company’s condensed consolidated financial statements presented in accordance with Generally Accepted Accounting Principles, or GAAP, management has disclosed certain non-GAAP financial measures for the statement of operations. The Company believes that an evaluation of its ongoing operations (and comparisons of its current operations with historical and future operations) would be difficult if the disclosure of its financial results were limited to financial measures prepared in accordance with GAAP. As a result, the Company is disclosing certain non-GAAP results in order to supplement investors’ and other readers’ understanding and assessment of the Company’s financial performance. Company management uses these measurements as aids in monitoring the Company’s ongoing financial performance from quarter to quarter, and year to year, on a regular basis and for financial and operational decision-making. Non-GAAP adjustments include stock-based compensation, depreciation and amortization and restructuring charges. From time to time in the future, there may be other items that the Company may exclude if the Company believes that doing so is consistent with the goal of providing useful information to management and investors. The Company has provided a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure. Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures as analytical tools. Investors are encouraged to review these reconciliations, and not to rely on any single financial measure to evaluate the Company’s business.

Non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies, which could reduce the usefulness of the Company’s non-GAAP financial measures as tools for comparison. Investors and other readers are encouraged to review the related GAAP financial measures and the reconciliation of non-GAAP measures to their most directly comparable GAAP measures set forth below and should consider non-GAAP measures only as a supplement to, not as a substitute for or as a superior measure to, measures of financial performance prepared in accordance with GAAP. Non-GAAP financial measures in this earnings release exclude the following:

Non-cash expenses for stock-based compensation. The Company has excluded the effect of stock-based compensation expenses in calculating the Company’s non-GAAP cost and expenses and net loss measures. Although stock-based compensation is a key incentive offered to employees, the Company continues to evaluate its business performance excluding stock-based compensation expenses. The Company records stock-based compensation expense related to grants of time-based and performance-based options, such as options that vest as a result of the Company’s market capitalization. Depending upon the size, timing and terms of the grants, as well as the probability of achievement of performance-based awards, this expense may vary significantly but will recur in future periods. The Company believes that excluding stock-based compensation better allows for comparisons from period to period.

Depreciation and amortization. The Company has excluded depreciation and amortization expense in calculating its non-GAAP cost and expenses and net loss measures. Depreciation and amortization are non-cash charges to current operations.

Restructuring charges. The Company has excluded restructuring charges in calculating its non-GAAP cost and expenses and net loss measures. Restructuring programs involve discrete initiatives designed to improve operating efficiencies and include employee termination, contract termination, and other exit costs associated with the restructuring program. The Company believes that excluding discrete restructuring charges allows for better comparisons from period to period.
