Digi's Q4 Revenue Surges 25%, But FY27 Guidance Signals a Deceleration and Keeps Us on the Sidelines

What happened

Digi International reported Q4 FY26 revenue of $143 million, up 25% year-over-year, with adjusted EBITDA margin expanding 350 basis points to 29.1%, reflecting improved operating leverage. However, management's FY27 guidance of only 14%–18% revenue growth implies a meaningful deceleration from the just-reported quarter and underscores a still-drawn-out transition to recurring revenue. The market viewed the print as a 'bump in the road,' with the article noting that slowing growth and a prolonged pivot to subscription revenue warrant caution. Compared to the prior master report's FY25 baseline of 1% revenue growth and ARR of $152 million, the acceleration is notable, but investors are pricing in continued double-digit expansion. Given the stock's rich valuation (P/E ~40x, EV/EBITDA ~21x, and a DCF anchor near $39 vs. recent trading in the mid-$40s), the risk/reward remains balanced rather than compelling.

Implication

The Q4 beat on revenue and margins is encouraging, but the conservative FY27 guidance suggests management expects a normalization rather than a continuation of the 25% growth rate. With a DCF intrinsic value around $39 and the stock trading in the mid-$40s, there is limited margin of safety, and any disappointment in ARR growth or the Solutions segment could trigger a de-rating. Watch for signs that ARR growth stays above 10% with stable churn and that IoT Solutions revenue outpaces the Products segment, as that would support a more bullish stance. Conversely, if Q1 FY27 revenue growth lands below 14% or margins contract unexpectedly, the premium multiple may compress sharply and justify a more defensive posture. For now, maintain a wait/monitor approach, and consider initiating a position only on a pullback toward the DCF anchor or on clear evidence of accelerating recurring revenue.

Thesis delta

The prior WAIT thesis remains intact: Digi's valuation already embeds ambitious growth, and the Q4 print, while strong, does not resolve the longer-term deceleration implied by FY27 guidance. The key shift is that revenue growth has clearly accelerated in Q4, but the guidance range of 14%–18% suggests management expects a step-down, making execution over the next two quarters the critical determinant. We maintain a WAIT and will monitor Q1 FY27 results and ARR trends for evidence that the recurring-revenue transition is progressing faster than expected.
