SPX Technologies (SPXC) has moved into focus after its second quarter 2026 earnings update, which paired higher sales and earnings with upgraded full year guidance and a sharp one day share price reaction.

The one day share price return of 10.2% after the earnings release comes against a quieter recent period, with a 30 day share price return of 5.22% lower and a year to date share price return of 8.05%, while the three year total shareholder return of 159.69% points to strong longer term momentum for SPX Technologies.

SPX Technologies now appears to be a higher quality business than many investors believed before this quarter. After such a sharp re rating, the key question is whether the current price still leaves enough value on the table.

Most Popular Narrative: 18.3% Undervalued

The most followed narrative currently places SPX Technologies at a discount to its fair value estimate, compared with the last close of $219.62, and ties that view directly to long term earnings power and margins.

A robust backlog and strong bookings growth in both HVAC (+19.5%) and Detection & Measurement (D&M, up 6% organically) divisions, combined with enhanced project pipeline visibility out through 2026, suggest sustained and resilient underlying end-market demand, driving forward revenue growth and enhancing earnings visibility.

Want to see what sits behind that backlog story? The narrative leans on compound revenue growth, rising profitability and a rich earnings multiple. The exact hurdle rates and margin path are what really matter.

Result: Fair Value of $268.83 (UNDERVALUED)

However, SPX Technologies still faces project timing and acquisition integration risks that could unsettle earnings and challenge the current narrative that the stock is 18.3% undervalued.

Another View on SPX Technologies Valuation

The 18.3% undervalued narrative rests on long term earnings power and a rich earnings multiple. Yet on a simple P/E comparison, SPX Technologies looks expensive. The stock trades on 38.6x earnings versus 27.3x for the US Machinery industry and a fair ratio of 34.6x, which points to limited margin for error if growth or margins disappoint.
