Previous wording

While we have worked to improve our global supply chain, challenges and potential disruptions still exist. We have experienced, and may continue to experience, increases in cost and limited availability of certain raw materials, components, and other inputs necessary to manufacture and distribute our products due to constraints and inflation within the global supply chain, and increases in wage costs and the cost and time to distribute our products. Uncertainty around inflationary pressures, interest rates, global conflicts, monetary policy, and changes in tariffs and tax laws could potentially cause new, or exacerbate existing, economic challenges that we may face, including the impact of foreign currency fluctuations on our results of operations, or result in an economic downturn or recession, which could negatively impact our business operations and results. Existing and future potential geopolitical dynamics may create economic, supply chain, energy, and other challenges, including disruptions to business operations, which has impacted, and may in the future negatively impact our business. In particular, international conflicts and disputes could create instability, have and may further result in sanctions, tariffs, and other measures that restrict international trade and may negatively affect our business operations and results.

In particular, international conflicts and disputes have created and may continue to create instability, including increased transportation and freight expenses, may further result in sanctions, tariffs, and other measures that restrict international trade and may negatively affect our business operations and results.

On February 20, 2026, our Board of Directors authorized a share repurchase program under which we may repurchase up to $30.0 million of our outstanding common stock. The program expires on December 31, 2027, or when the maximum authorized dollar amount has been utilized, whichever occurs first. Repurchases under the program may be made from time to time through open market purchases at prevailing market prices, in compliance with Rule 10b-18 under the Exchange Act, including through Rule 10b5-1 trading plans. The share repurchase program does not obligate us to make any repurchases and may be modified, suspended, or terminated by us at any time without prior notice. The amount and timing of repurchases are subject to a variety of factors including liquidity, share price, market conditions, and legal requirements. For the three months ended March 31, 2026, we repurchased and retired 298,100 shares of our common stock for a total of $1.9 million.

Sales revenue increased $8.3 million, or 5.6%, for the six months ended June 30, 2026 from the six months ended June 30, 2025. The increase was primarily attributable to higher demand in our international markets as well as the favorable impact of foreign exchange rates, partially offset by channel mix within the U.S. We sold approximately 99,600 portable units during the six months ended June 30, 2026 compared to approximately 89,400 portable units sold during the six months ended June 30, 2025, an increase of 11.4%.

Current report — wording carried from elsewhere

Current report — wording carried from elsewhere

Cost of sales revenue increased $3.6 million, or 4.4%, for the six months ended June 30, 2026 from the six months ended June 30, 2025 due primarily to an increase in the number of systems sold.

Current report — wording carried from elsewhere

Gross margin on sales revenue increased to 45.4% for the six months ended June 30, 2026 from 44.8% for the six months ended June 30, 2025. The increase was driven by manufacturing cost leverage from higher units sold and lower cost premiums associated with open-market purchases of semiconductor chips used in our portable oxygen concentrators and reduced warranty-related costs resulting from product quality improvements.

Income tax benefit decreased less than $0.1 million, or 31.2%, for the six months ended June 30, 2026 from the six months ended June 30, 2025. We continued to record a valuation allowance on the use of deferred tax assets in the current and prior periods.
