Why AltaGas Stock Is Back In Focus After A Major Debt Move

AltaGas (TSX:ALA) has just completed a US$750 million senior unsecured notes issue at 5.75% due 2031, a financing decision that directly targets its existing debt stack and interest costs.

The new bonds are guaranteed by AltaGas and rank equally with its other senior unsecured obligations. Management is directing the proceeds toward repaying credit facility borrowings and retiring medium term notes.

AltaGas has ridden a strong run over the past year, with the share price delivering a year to date gain of 26.39% and a 1 year total shareholder return of 26.78%. The 3 year and 5 year total shareholder returns of 125.77% and 155.58% point to momentum that has been building over a longer stretch, even as the 90 day share price return has softened slightly. This sets the latest debt refinancing against a backdrop of sustained compounding for long term holders.

Most Popular Narrative: 11.6% Undervalued

On the widely followed narrative, AltaGas screens as undervalued, with an assessed fair value of around CA$60.27 versus the CA$53.31 last close. This puts the fresh debt issue into a tighter pricing frame.

AltaGas's growing LPG export platform (RIPET, Ferndale, and REEF construction with proven commercial support and phased optimization/expansion plans) aligns with increasing Asian demand for low-carbon transitional fuels, creating diversified, higher-margin revenue streams and margin expansion opportunities.

See why 31 investors see AltaGas as 12% undervalued.

Result: Fair Value of CA$60.27 (UNDERVALUED)

Still, AltaGas faces policy risk around decarbonization efforts and high ongoing infrastructure spending, either of which could pressure future earnings and challenge today’s valuation story.

Another View On AltaGas Valuation

The first take on AltaGas uses a discounted cash flow style fair value. A different yardstick, the P/E ratio, tells a less comfortable story. AltaGas trades at 27x earnings, which is about double the global gas utilities average of 13.8x and still well below a fair ratio of 32.7x that the model suggests the market could move toward.

That gap means the stock appears cheaper than this fair ratio implies, yet expensive compared with the wider industry and still rich versus some peers at 44.3x. For an investor weighing fresh capital, this raises a question: is this a margin of safety or a signal that expectations leave limited room for mistakes on execution and regulation?
