Other Events.

On March 9, 2026, Pulse Biosciences, Inc. (the “Company”) issued a press release announcing long-term follow-up data from its nPulse™ Vybrance™ Percutaneous Electrode System first-in-human feasibility study (the “Study”). These data were presented at the North American Society for Interventional Thyroidology 2026 meeting, on March 6, 2026, in Portland, Oregon, by Professor Stefano Spiezia, Chief of Endocrine Surgery at Ospedale del Mare, a principal investigator in the Study.

The Study is an extension of the initial feasibility study conducted by Prof. Spiezia at Ospedale del Mare in Naples, Italy, which evaluated nsPFA energy for the treatment of benign thyroid nodules. The Study was extended to allow for long-term follow-up of a subset of the patients included in the initial study. A total of 21 patients were subsequently monitored between 15 and 22 months to evaluate volume reduction trends over time.

Key findings from the Study reported by the Company include:

	●	Durable 15-22 month results with an average 74% volume reduction of treated benign thyroid nodules with overwhelming satisfaction reported
	●	Continued volume reduction improvements from 1 month through 22 months
	●	No regrowth of nodules at 15-22 months
	●	Patient reported Cosmetic Satisfaction: 100% were Highly Satisfied at final follow-up
	●	Patient reported Overall Satisfaction: 95% were Highly Satisfied at final follow-up
	●	No serious adverse events
	●	No intranodular fibrosis detected on ultrasounds at 15-22 months
	●	Potential for clinical durability of benign thyroid ablation
