The results were solid with revenue increasing 33% to $62.7 million, which topped expectations at $61.9 billion. The company's gross margin ticked up from 52.9% to 54.1%, and it reported an adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) loss of $6.3 million with its margin expanding from negative 8.1% to negative 10.1%. Allbirds also continued to expand its brick-and-mortar format, adding four stores to bring its total to 31.

"Revenue was strong across channels and geographies, growing 33% year over year, with notable strength in U.S. physical retail," Co-CEO Joey Zwillinger said in a statement. "Importantly, we saw strong consumer response in the quarter to our new product innovation, including our new Perform Apparel line."

Allbirds' guidance seemed to call for a sharp decline in revenue in the fourth quarter, projecting full-year revenue of $270 million to $272 million, up 23% to 24%, implying fourth-quarter revenue of roughly 15%. Still, that forecast was essentially in line with analyst estimates at $271.9 million.

While the third-quarter numbers were mostly better than expected, investors may have been looking for strong beats from the Silicon Valley company, especially since this was its debut earnings report.

Now what

Allbirds has a unique approach to footwear with a focus sustainability and comfort through materials like merino wool, eucalyptus tree fiber, and sugarcane-based foam. Allbirds' gross margin around 54% is especially strong for a footwear brand, which indicates that the company has a pricing advantage.

At a market cap of $2.3 billion, the stock trades at a price-to-sales ratio of 8, which is pricy for a consumer brand, and the footwear industry is notoriously competitive; Allbirds is competing against giants like Nike and Adidas.

With market sentiment changing, Allbirds stock could come under pressure in 2022. We'll learn more when the company provides 2022 guidance, which may not come until March.
