Ambac Financial Group stock (US0234361089) closed at USD 4.41 on the New York Stock Exchange on September 21, 2026, at 3:58 p.m. Eastern Time, down USD 0.09, or 2.00 percent, from the prior close. The former AMBC listing now trades under the OSG symbol after the company changed its name and ticker, according to MarketBeat on September 22, 2026.

AMBC now trades as OSG

The reported listing update identifies Octave Specialty Group as the current company name and OSG as the current NYSE ticker, while AMBC is shown as the previous symbol. The dated USD 4.41 quotation therefore refers to the successor listing rather than an unchanged AMBC ticker.

Quarterly earnings missed estimates

For the quarter reported on August 6, 2026, the company posted EPS of negative USD 0.04, missing the consensus estimate of negative USD 0.01 by USD 0.03, according to MarketBeat. Revenue for the same quarter was USD 83.00 million versus an estimate of USD 22.79 million, a USD 60.21 million difference that contrasts with the earnings shortfall.

The company also recorded a negative net margin of 51.10 percent and return on equity of 0.44 percent for the period cited by MarketBeat. The combination of revenue above the estimate and EPS below consensus makes profitability the more important operating issue than the top-line comparison.

Target remains above the stock

MarketBeat reported on September 22, 2026, that the shares carried a consensus rating of Hold and an average price target of USD 11.50. The target was USD 7.09 above the September 21 closing price of USD 4.41, while the portal calculated potential upside of 160.8 percent.

The same market overview listed two Buy ratings, two Hold ratings and one Sell rating, producing the Hold consensus. It also listed a high target of USD 15.00 and a low target of USD 8.00, giving investors a wide USD 7.00 spread between the published target extremes.
