Inogen: Structural, Supply Chain Headwinds Remain

Summary Inogen came in with a mixed set of numbers, however, longer-term structural headwinds remain in situ. The hold rating on INGN remains intact following Q2 earnings, and I've noticed similar themed risks looking ahead. Chief to the downside risk is a further slowdown in its B2B and D2C segments which could accelerate losses further. Balancing the debate is the return INGN generates on its invested capital. Investment summary After carefully digesting the moving parts involved with previous analyses, there remains no change to the thesis on Inogen, Inc. (NASDAQ:INGN). I'm reiterating a hold on INGN after: a). The company's most recent set of numbers and; b). Uncertainties to FY22 guidance from ongoing supply-chain headwinds. I've covered INGN at lengths previously both here and here and noted the following thematic has remained consistent after the second quarter: INGN's direct-to-consumer ("DTC") and business-to-business ("B2B") segments have been adversely impacted by the pandemic - in 2020, a combination of limited salesforce expansion, reduced volume and purchase order cancellations; by Q1 FY2 - lagging growth in the DTC and B2B businesses clamped margin growth. "Pricing dynamics are more extreme in the portable oxygen concentrator ("POC") market relative to others. INGN's product mix is the most expensive option within the segment." The wind-back of COVID-19 protocols combined with this less benign pricing environment are key headwinds set to impact INGN's business model looking ahead. Fluidity in supply of semiconductors and semiconductor inventory are key challenges until POC redesign efforts are realized. With that, trends remain unchanged and supply chain disruptions in particular have blurred management's ability to provide full-year guidance. INGN Q2 earnings walkthrough illustrates challenges INGN came in with a mixed set of second quarter numbers vertically down the P&L. Revenue of $103.4 million ("mm") saw a marginal year-on-year increase, with growth of ~180bps at the top line. The bulk of the upside was underpinned by a 22% YoY gain in rental revenue to $14.08mm, whereas sales revenue tightened ~110bps YoY to ~$89.3mm. Certainly, Medicare and various commercial payors have reduced the bureaucratic overhang for oxygen therapy since the onset of the pandemic. This may inflect positively to revenue on INGN's rental business. At the same time, however, its B2B channels have continued to narrow as COVID-19 continues to play havoc on travel, physician office restrictions, and labor shortage in hospitals. Most notably are the supply chain issues INGN continues to incur as a result of global semiconductor shortages. In Q1 FY22, it had to temporarily suspend operations for ~6 weeks due to this issue. The shortages have limited the company's ability to produce and sell systems and batteries and may potentially hurt FY22 numbers if it happens again. This is coupled by the surging gas price, hurting margins for semiconductor manufacturers and buyers downstream. To offset, management had started to re-engineer some POC components to overcome this hurdle, but this will take time. INGN has, per the 10-Q: "attempted to mitigate the impact of this increased supply shortage, but it has and will likely continue to negatively impact [its] ability to manufacture product, and [it] could be forced to slowdown or temporarily halt production again." However, the impact was still felt at the cost of revenue ("COR") line, with the COR margin in Q2 FY22 spiking 5 percentage points YoY to 55.2% on quarterly COR of $57.1mm ($2.50/share). Important for INGN, is that it saw some upside in its international B2B segment, with a c.71.5% YoY gain in sales to $37.4mm for the quarter. Domestically, however, B2B sales narrowed 59.3% to $11.2mm YoY, but the company gained traction towards the back end of the quarter as it began to fulfil backlog demand within the channel. Moreover, B2B receivables increased 39.2% YoY to $25.6mm, as seen in Exhibit 1. The segment also contains one customer with a receivable balance of $3.8mm as of 30 June, that has received extended payment terms via an offered direct financing plan. Exhibit 1. INGN net accounts receivable - note c.39% YoY gain to ~$25.7mm in B2B receivables Data: INGN Q2 FY22 10-Q; pp.13 - Accounts receivable and allowance for bad debts, returns, and adjustments.
