Hims & Hers Health narrowed its sales outlook after higher costs in the third quarter resulted in an unexpected loss.

The digital healthcare company said it now expects full-year revenue to be $3.13 billion to $3.15 billion, compared with its earlier projection of $3.1 billion to $3.3 billion. Hims also lowered its outlook for adjusted earnings before interest, taxes, depreciation and amortization.

For the current fourth quarter, Hims expects revenue to be $875 million to $895 million. That would be below the $953.8 million that analysts are forecasting.

The new outlook came after the company recorded higher expenses in the third quarter, which offset revenue growth and resulted in a quarterly loss. Hims also added Andrew Huberman to its board and signed several multimillion advertising deals with the podcaster and professor.

In the third quarter, Hims posted a loss of $33 million, or 14 cents a share, compared with a profit of $15.8 million, or 6 cents a share, a year earlier. Analysts expected a profit of 6 cents a share.

The cost of revenue more than doubled during the quarter and total operating expenses increased 34%. Gross margin fell to 57% from 74% the year before.

That offset some of the growth in revenue, which jumped 49% to $890.4 million. Analysts surveyed by FactSet forecast revenue of $893.1 million.

U.S. sales were up 21%, while revenue in the rest of the world more than quadrupled. The number of subscribers at the end of the quarter was up 13%, while the monthly revenue per average subscriber rose 30%.

Separately, Hims said it was expanding the size of the board to 10 directors to add Huberman. Huberman, 51, is a neurobiology professor at Stanford and hosts The Huberman Lab, a podcast about neuroscience and personal health.

Along with joining the board, Huberman signed multiple deals with Hims to provide brand marketing advisory services.

Under the first deal, which spans two years, Huberman will provide scientific and brand marketing advisory services to Hims in exchange for $3.5 million in cash. Huberman can also create short-form videos for Hims' paid advertising channels for up to an additional $1 million a year.

Additionally, Huberman's media company, Scicomm Media, agreed to provide podcast advertising services to Hims for up to three years for an annual fee of $5 million in cash.
