Comparison of the Six Months Ended June 30, 2026, to the Six Months Ended June 30, 2025
Current report
Net Sales and Cost of Goods Sold
Current report
Net sales and cost of goods sold was $5.0 million and $4.5 million, respectively, during the six months ended June 30, 2026, resulting from the Company completing commercial implants at twenty-nine hospitals in the US. Net sales and cost of goods sold were significantly lower during the six months ended June 30, 2025, resulting from then-recent FDA approval of our WiSE CRT System in April 2025. During the six months ended June 30, 2025, we had commercial implants at three hospitals in the US.
Current report
Gross Profit, and Gross Margin
Current report
Gross profit increased by $0.4 million, or 520.0% for the six months ended June 30, 2026, as compared to the six months ended June 30, 2025, resulting from an increase in sales volume and a higher average selling price. Our gross margin was positively affected and will continue to be affected in the near future by the use of inventory that was previously expensed during our clinical trial, although the benefit continues to decrease over time as previously expensed inventory is utilized. Gross margin was 10.5% for the six months ended June 30, 2026, compared to 50% for the six months ended June 30, 2025. Excluding the use of previously expensed inventory, we would have had a negative gross margin of 20.90% and 51.18% for the six months ended June 30, 2026 and 2025, respectively. The improvement in gross margin, excluding the use of previously expensed inventory, is the result of a higher average selling price, a lower standard cost, and increased manufacturing efficiencies during the six months ended June 30, 2026, as compared to the six months ended June 30, 2025.
Current report
Research and Development
Current report
Research and development expenses increased by $1.7 million, or 14.7%, during the six months ended June 30, 2026, as compared to the six months ended June 30, 2025. Clinical expenses increased by $0.8 million as a result of higher expenses related to WiSE CRT post-approval study. Facility-related expenses and depreciation increased by $0.6 million, as a result of our expansion of research and development activities. Quality assurance and contract manufacturing expenses increased by $0.5 million primarily due to expenses incurred to support product development activities. These increases were partially offset by a $0.2 million decrease in personnel-related expenses due to an increase in capitalized labor costs during the six months ended June 30, 2026, as compared to the six months ended June 30, 2025.
Current report
Other expense, net
Current report
Net cash provided by financing activities during the six months ended June 30, 2026 was $76.3 million, compared to $46.9 million during the six months ended June 30, 2025, representing an increase of $29.4 million. This increase was primarily attributed to the $29.7 million increase in proceeds from a capital raise, net of issuance cost, during the six months ended June 30, 2026, which was partially offset by a $0.3 million decrease in proceeds from exercise of stock options during the six months ended June 30, 2026, as compared to the six months ended June 30, 2025.

Previous wording
Our WiSE CRT System received approval from the FDA for commercial distribution in April 2025, and we began commercializing WiSE during the second quarter of 2025. During the three months ended March 31, 2026, we had 41 commercial implants at 19 hospitals in the US, and recognized revenue of $2.4 million. An additional 22 physicians were trained to implant the WiSE CRT System, and 16 additional purchase agreements were signed with target LMR sites during the three months ended March 31, 2026. The commercial potential of and our ability to successfully commercialize WiSE is unproven and will require, among other things, effective sales, marketing, manufacturing, distribution, information systems and pricing strategies, as well as compliance with applicable laws and regulations.

Previous wording
We derive most of our revenue from sales of WiSE to the hospital facilities that implant our WiSE CRT System. We recognize revenue upon the transfer of goods or services to a customer at an amount that reflects the expected consideration to be received in exchange for those goods or services. Specifically, revenue from the sale of WiSE is recognized at an amount that reflects the expected consideration upon notice that our products have been used in a surgical procedure. Our revenue fluctuates primarily based on the volume of procedures performed. Our revenue is expected to continue to fluctuate in the future from quarter-to-quarter due to a variety of factors, including the success of our sales force in expanding adoption of WiSE in new hospitals and the number of physicians who are aware of and implant WiSE.
Current wording
We derive most of our revenue from sales of WiSE to the hospital facilities that implant our WiSE CRT System. We recognize revenue upon the transfer of goods or services to a customer at an amount that reflects the expected consideration to be received in exchange for those goods or services, net of rebates. Specifically, revenue from the sale of WiSE is recognized at an amount that reflects the expected consideration upon notice that our products have been used in a surgical procedure. We account for rebates as a reduction to revenue, calculated based on the terms agreed with the customer. Our revenue fluctuates primarily based on the volume of procedures performed. Our revenue is expected to continue to fluctuate in the future from quarter-to-quarter due to a variety of factors, including the success of our sales force in expanding adoption of WiSE in new hospitals and the number of physicians who are aware of and implant WiSE.
Previous wording
We calculate gross margin as gross profit divided by revenue. Our gross margin has been and will continue to be affected by a variety of factors, primarily by our manufacturing costs, pricing, and the use of inventory that was previously expensed during our clinical trial. Our gross margin is expected to decrease over the near term as we continue to utilize inventory that was previously expensed as research and development costs, but over the long term our gross margin may increase to the extent our production volume increases as our fixed manufacturing costs would be spread over a larger number of units, thereby reducing our per-unit manufacturing costs. We expect our gross margin will fluctuate from period to period based upon the factors described above.

Previous wording
The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business. For the three months ended March 31, 2026 and 2025, we incurred a net loss of $17.1 million and $10.6 million, respectively. During the three months ended March 31, 2026 and 2025, we had negative cash flows from operations of $20.3 million and $13.6 million, respectively. As of March 31, 2026, we had working capital of $42.0 million and accumulated deficit of $419.3 million. These factors raise substantial doubt about our ability to continue as a going concern. Until we are able to generate consistent and sufficient revenue from sales of our WiSE CRT System, our ability to continue as a going concern is dependent on our ability to raise additional capital through the issuance of additional common stock or borrowings from financial institutions. Our ability to obtain additional capital in the equity capital markets is subject to several factors, including market and economic conditions, our performance, and investor sentiment with respect to our company and our industry.

Accrued expenses decreased by approximately $0.6 million as of March 31, 2026, compared to December 31, 2025. The decrease primarily resulted from the payout of annual bonuses, which was partially offset by an increase in deferred revenue from sales of our WiSE CRT System. Additionally, operating lease liabilities decreased by approximately $0.1 million, which contributed to the overall decrease in current liabilities.
Current wording
Current liabilities, consisting primarily of accounts payable, accrued liabilities, lease obligations, interest payable, and current portion of notes payable increased by approximately $38.0 million as of June 30, 2026, compared to December 31, 2025.
