Catalysts Driving Growth

High Prospects in the POC Space: Inogen is poised for growth due to its innovative POCs, which are superior to conventional oxygen therapy. The proprietary Inogen One and Inogen Rove systems provide supplemental oxygen anytime and anywhere, enhancing patient convenience.

As of Dec. 31, 2023, Inogen had 33 pending patent applications and 87 issued patents related to its respiratory devices, bolstered by the acquisition of Physio-Assist, which added more patents to its portfolio.

Inogen’s products are marketed internationally through distributors and sold directly to patients and prescribers in the United States. The POC market is projected to rise from $1.58 billion in 2022 to $3.03 billion by 2030 at an 8.5% CAGR.

Inogen sold 41,300 systems in the second quarter of 2024, a 21.1% increase year over year, and 75,200 systems in the first half of 2024, a 23.3% rise, which boosted stock performance.

Product Portfolio: Inogen's performance is enhanced by its expanding product portfolio, highlighted by the upcoming launch of Inogen Rove 4 in the third quarter of 2024, which received FDA 510(k) clearance in June. This model features a new flow setting, an eight-year service life and the highest oxygen production, making it the lightest POC on the market.

Additionally, Inogen Rove 6, launched in July 2023 in the United States, offers an eight-year service life. These advancements enhance Inogen’s competitive edge and growth potential in the POC market.

Inogen is focusing on research and development to enhance its oxygen therapy products and maintain market leadership. In the second quarter of 2024, R&D expenses rose 30.8% year over year, representing 6.3% of total revenues, primarily due to the Physio-Assist acquisition and increased product development costs, demonstrating the company’s commitment to innovation.
