Fresh data from IDT (IDT) subsidiary NRSInsights showed December 2025 same-store sales up 4.5% year over year, with average prices for the top 500 items rising 2.3% across its retail point of sale network.

That pickup in NRS same-store sales and pricing lands against a mixed share price backdrop, with a recent 90 day share price return of 8.9% and a 1 year total shareholder return of 12.1%. The 5 year total shareholder return of about 2.7x suggests longer term holders have already seen substantial value creation, while recent momentum looks more muted.

If this kind of retail and payments story has your attention, it can be worth widening the lens and checking out fast growing stocks with high insider ownership for other fast growing names with committed insiders.

With shares up 12.1% over the past year but still trading at a sizeable discount to the US$80 analyst price target and an implied intrinsic value gap, you have to ask: is IDT quietly undervalued, or is the market already baking in the next leg of growth?

Most Popular Narrative: 35.8% Undervalued

With IDT last closing at US$51.38 against a narrative fair value of US$80, the current price sits well below that implied estimate.

The company's intention to continue repurchasing shares and increasing dividends, backed by strong cash generation, suggests improved earnings per share (EPS) growth potential. With ongoing subscription revenue growth and strategic investments in AI and digital channels, net2phone's future performance is expected to boost revenue and improve adjusted EBITDA margins.

It is worth asking what kind of earnings path and margin profile could justify that higher fair value. The narrative leans on steady profits, richer margins, and a future P/E multiple that stands above the wider telecom group.

Result: Fair Value of $80 (UNDERVALUED)

However, you still need to weigh risks such as the significant working capital needs at BOSS Money, as well as potential integration or spending issues if future growth depends on acquisitions.

Another View: Market Ratios Tell A Different Story

Our fair value narrative points to meaningful upside, yet the current P/E of 15.9x sends a mixed signal. It sits above the fair ratio of 13.3x and well above peers at 8.8x, which hints at less margin of safety if expectations around growth or margins are tested.
