Inogen to Announce Fourth Quarter and Full Year 2022 Financial Results on February 23, 2023

Inogen, Inc. (Nasdaq: INGN), a medical technology company offering innovative respiratory products for use in the homecare setting, today announced unaudited preliminary revenue results for the fourth quarter and the full year ended December 31, 2022.

The Company estimates preliminary, unaudited total revenue in the fourth quarter of 2022 to be in the range of $87.5 million to $88.5 million, representing year-over-year growth of 14.5% to 15.8%. Full year 2022 total preliminary, unaudited revenue is expected to be in the range of $376.7 million to $377.7 million, representing year-over-year growth of 5.2% to 5.5%.

Foreign exchange fluctuations are estimated to have a $1.3 million impact on preliminary, unaudited fourth quarter 2022 revenue and a $5.3 million impact on preliminary, unaudited full year 2022 revenue.

These preliminary, unaudited results are within the previously projected fourth quarter guidance range of $87 million to $92 million.

“Despite the prevailing macroeconomic pressures and headwinds resulting from our efforts to continue upgrading the operating disciplines in our DTC commercial team, preliminary fourth quarter 2022 results came in within the expectations we had shared during our third quarter earnings call,” said Nabil Shabshab, President and Chief Executive Officer. “We expect productivity to improve in the near-term as the tenure of our DTC team increases and we continue partnering with our B2B channel to manage economic pressures. While we continue to prioritize investments to drive medium to long-term growth, we are also diligently managing operating expenses in support of our plans for long-term profitability.”
