Business Overview and History
Inogen, Inc. (INGN) is a medical technology company that has revolutionized the portable oxygen concentrator (POC) market. Founded in 2001, the company has established itself as a leading provider of innovative respiratory products for use in the home care setting. With a focus on improving the quality of life for patients suffering from chronic respiratory conditions, Inogen has consistently pushed the boundaries of POC technology, delivering solutions that enhance mobility and independence.
Inogen, Inc. was incorporated in Delaware on November 27, 2001, with the primary goal of developing, manufacturing, and marketing innovative portable oxygen concentrators (POCs) for patients requiring long-term oxygen therapy. The company's founders set out to redefine how oxygen therapy is delivered, moving away from traditional stationary oxygen concentrator systems and oxygen tanks or cylinders for mobile use.
Inogen's breakthrough came with the development of its proprietary Inogen One and Inogen Rove systems. These portable devices concentrate the air around the patient to provide a continuous source of supplemental oxygen, significantly reducing reliance on stationary concentrators and scheduled deliveries of tanks with finite oxygen supplies. This innovation has allowed patients to enjoy greater freedom and mobility in their daily lives.
Throughout its history, Inogen has faced various challenges, including supply chain disruptions and macroeconomic headwinds. The company has navigated these obstacles by focusing on cost management, streamlining operations, and maintaining a strong commitment to research and development. This approach has enabled Inogen to continually improve its products and maintain its position as a leader in the portable oxygen therapy market.
Financial Performance and Liquidity
Inogen's financial performance over the past few years has been mixed, reflecting the challenges faced by the company and the broader medical device industry. In 2023, the company reported total revenue of $315.66 million, a decrease of 16.3% compared to 2022. Net income for the year was a loss of $102.45 million, a significant decline from the $83.77 million loss reported in 2022. The company's operating cash flow (OCF) for 2023 was -$3.23 million, while free cash flow (FCF) stood at -$30.25 million.
For the most recent quarter (Q3 2024), Inogen reported revenue of $88.83 million, representing a 5.8% increase year-over-year. The net loss for the quarter was $5.96 million. Notably, the company showed improvement in cash flow metrics, with OCF of $6.99 million and FCF of $16.09 million for the quarter.
The company's gross profit margin has fluctuated, reaching 40.2% in 2023, down from 41.1% in the previous year. Inogen's operating margin has also been negative, standing at -34.7% in 2023, a decrease from -22.4% in 2022. These financial metrics reflect the impact of supply chain disruptions, increased competition, and the company's ongoing efforts to streamline operations and invest in research and development.
In terms of liquidity, Inogen's current ratio stood at 2.66 as of the latest reporting period, indicating a strong ability to meet short-term obligations. The company's quick ratio was 2.34, further underscoring its liquidity position. Inogen's cash and cash equivalents, including marketable securities, totaled $124.25 million as of Q3 2024, providing a solid foundation for future growth and investment. The company has a debt-to-equity ratio of 0.1087, with no outstanding debt and no credit facilities or credit lines.
Inogen operates through two main revenue segments: Sales Revenue and Rental Revenue. The Sales Revenue segment, which includes both business-to-business and direct-to-consumer sales of Inogen Rove, Inogen One, and Inogen At Home systems, has shown growth. In the nine months ended September 30, 2024, Inogen sold approximately 119,100 systems, up 23.5% from the same period in 2023. This increase was primarily driven by higher international and domestic business-to-business sales.
The Rental Revenue segment, derived from renting Inogen One and Inogen At Home systems to patients, has faced challenges. As of September 30, 2024, Inogen had approximately 51,400 oxygen rental patients, slightly down from 51,900 in the previous year. Rental revenue decreased by 9.2% in the nine months ended September 30, 2024, compared to the same period in 2023, primarily due to a higher mix of lower private-payor reimbursement rates.
For the nine months ended September 30, 2024, Inogen reported total revenue of $255.62 million, a 6.6% increase from the same period in 2023. Gross profit was $118.45 million, with a total gross margin of 46.3%. Operating expenses totaled $149.58 million, including $15.71 million in research and development, $78.91 million in sales and marketing, and $54.96 million in general and administrative expenses. The company reported a net loss of $26.13 million for this nine-month period.
While Inogen does not provide a detailed breakdown of revenue by geographic markets, it is known that the majority of the company's revenue is derived from the United States, with international sales accounting for approximately 20-30% of total revenue in recent years.
Looking ahead, Inogen has raised its revenue expectations for the full year 2024 to be within $329 million to $331 million, reflecting approximately 4% to 5% year-over-year growth. The company expects gross margins to be in the low-to-mid 40s in the second half of 2024. Despite achieving a second consecutive quarter of adjusted EBITDA profitability in Q3 2024, Inogen anticipates ending the second half of 2024 with an adjusted EBITDA loss.
Operational Highlights and Strategic Initiatives
Inogen has been actively implementing various strategic initiatives to drive growth and enhance its market position.
