DGII

Digi is a high-margin (62.9% gross), cash-generative networking/IoT business, but the top line has gone nowhere: revenue is $430M in FY2025, still below the FY2023 peak of $445M, and grew just +1.5% YoY. The headline that flatters the stock — net income +81.3% and diluted EPS +77% to $1.08 — is not matched by the operating engine, where operating income rose a more pedestrian +17.1%. That gap means a large slice of the 'earnings growth' came from below the operating line (lower interest and/or tax), not from the core business growing. On a like-for-like operating basis this is a roughly flat company having a good earnings-mix year.

Where Digi genuinely shines is cash conversion. Operating cash flow of $108M (+29.9%) against only $2.63M of capex implies ~$105M of free cash flow — far above the $40.8M GAAP net income, because $34.0M of D&A (largely amortization of intangibles from the Accelerated, Opengear and Ventus acquisitions) is non-cash. That reframes the optically frightening 67.8x P/E into a ~26x price-to-FCF, which is full but not absurd for a steady cash compounder. The balance sheet is serviceable: liabilities/equity of 0.45x and $636M of equity, though the $159M long-term credit-facility balance ($160.0M outstanding per the 10-K, floating at Term SOFR + 1.75–2.75%) sits against just $21.9M of cash (down 20.4%), so the deleveraging-and-FCF story is the real investment case, not growth.
