Pulse Biosciences, Inc. (Nasdaq: PLSE), a company primarily focused on leveraging its novel and proprietary Nanosecond Pulsed Field Ablation (nsPFA) technology for the treatment of atrial fibrillation, today announced financial results for the second quarter ended June 30, 2023.

Business Updates

• Demonstrated that an nsPFA cardiac clamp can consistently perform transmural ablations in cardiac muscle up to approximately 25 millimeters thick in 1.25 seconds in preclinical studies.
• Demonstrated that an nsPFA cardiac ablation catheter can consistently perform circumferential ablations of targeted pulmonary veins in a single shot in approximately 5 seconds in preclinical studies.
• Three abstracts highlighting the results of preclinical studies using an nsPFA cardiac ablation catheter device were presented by physician collaborators at the Annual Heart Rhythm Society Meeting.
• Achieved positive patient tolerance, safety and tissue response in a first-in-human feasibility study of nsPFA delivery for the ablation of benign thyroid nodules.
• Entered into a $65 million private placement stock purchase agreement with Robert Duggan, the Company’s Executive Chairman, effectively canceling all indebtedness owed by the Company to Mr. Duggan.
• Further strengthened the balance sheet with gross proceeds of $14.6 million in the second quarter through the exercise of warrants from the Company’s June 2022 Rights Offering.

“We are encouraged by the preclinical results we have achieved with the nsPFA cardiac clamp and catheter products. Our novel devices, combined with our unique mechanism of action, are demonstrating the potential to advance the standard of care for the treatment of atrial fibrillation. Additionally, we view the preliminary findings in our first-in-human feasibility study using our proprietary nsPFA surgical end-effector to ablate benign thyroid nodules as a significant validation of our engineering and the potential for nsPFA to deliver safe and effective human tissue ablation in surgery,” said Kevin Danahy, Chief Executive Officer of Pulse Biosciences. “Looking ahead, we remain focused on gaining clearance for a cardiac ablation clamp and advancing the catheter toward first-in-human studies.”

Second Quarter 2023 Results

Total GAAP cost and expenses, representing cost of revenues, research and development, sales and marketing, and general and administrative expenses, for the three months ended June 30, 2023, were $10.2 million compared to $14.3 million for the prior year period. Non-GAAP cost and expenses for the three months ended June 30, 2023, were $8.8 million compared to $12.2 million for the prior year period. The decrease in operating expenses compared to the prior year period was driven by the prior headcount reduction and restructuring.

GAAP net loss for the three months ended June 30, 2023 was ($9.9) million compared to ($14.0) million for the three months ended June 30, 2022. Non-GAAP net loss for the three months ended June 30, 2023, was ($8.5) million compared to ($11.9) million for the three months ended June 30, 2022.

Cash and cash equivalents totaled $58.7 million as of June 30, 2023, compared to $14.8 million as of June 30, 2022 and $54.1 million as of March 31, 2023. Cash used in the second quarter of 2023 was $10.0 million compared to $12.8 million in the same period in the prior year and $7.2 million used in the first quarter of 2023. The increase of second quarter cash usage was primarily due to the timing of certain nonrecurring payments. In the second quarter of 2023, the Company received $14.6 million in gross proceeds from the exercise of warrants issued in its June 2022 rights offering.

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.

Forward-Looking Statements

All statements in this press release that are not historical are forward-looking statements, including, among other things, statements relating to the effectiveness of the Company’s nsPFA technology and CellFX System to non-thermally clear cells while sparing adjacent non-cellular tissue, statements concerning the Company’s expected product development efforts, such as advancement of its cardiac clamp through the appropriate FDA regulatory path and possible initiation of a first-in-human safety feasibility study of its nsPFA cardiac ablation catheter system, statements concerning the Company’s future regulatory strategies and possible government clearances and approvals, statements concerning customer adoption and future use of the CellFX System to address a range of conditions such as atrial fibrillation and benign thyroid nodules, statements about the Company’s future financing opportunities and operating expenses, and Pulse Biosciences’ expectations, whether stated or implied, regarding whether the Company’s nsPFA technology will become a disruptive treatment option for treating cardiac arrhythmias, benign thyroid nodules or any other medical condition and whether future clinical studies will show the CellFX System is safe and effective to treat atrial fibrillation, benign thyroid nodules or any other medical condition, and other future events. These statements are not historical facts but rather are based on Pulse Biosciences’ current expectations, estimates, and projections regarding Pulse Biosciences’ business, operations and other similar or related factors. Words such as “may,” “will,” “could,” “would,” “should,” “anticipate,” “predict,” “potential,” “continue,” “expects,” “intends,” “plans,” “projects,” “believes,” “estimates,” and other similar or related expressions are used to identify these forward-looking statements, although not all forward-looking statements contain these words. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties, and assumptions that are difficult or impossible to predict and, in some cases, beyond Pulse Biosciences’ control. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described in Pulse Biosciences’ filings with the Securities and Exchange Commission. Pulse Biosciences undertakes no obligation to revise or update information in this release to reflect events or circumstances in the future, even if new information becomes available.
