Stem stock falls after August earnings miss as guidance stays in focus

Stem, Inc. stock (ISIN US85859N1028) is trading at USD 4.61 on the New York Stock Exchange as of September 18, 2026, marking a steep drop of 69.4% from the USD 15.09 level at the beginning of 2026 and underscoring how the market has reacted to its latest results and outlook over the course of the year.

Quarterly loss and revenue after August 12 results

According to MarketBeat, Stem, Inc. reported its most recent quarterly figures on August 12, 2026, posting a loss per share of USD 1.58 for the quarter against analyst expectations of a USD 1.75 loss, so the result beat consensus by USD 0.17 despite remaining clearly negative.

In the same August 12, 2026 quarter, revenue reached USD 33.65 million compared with analyst estimates of USD 36.65 million, so sales came in USD 3.00 million below expectations and highlighted that top-line growth did not fully meet market forecasts even as the loss per share was slightly better than anticipated, according to MarketBeat.

Guidance and earnings outlook versus current valuation

Guidance remains an important checkpoint for investors after the August 12, 2026 release, with earnings for Stem projected to improve modestly in the coming year from a negative USD 7.04 per share to a negative USD 6.96 per share, indicating only a small expected narrowing of losses of USD 0.08 per share based on forecasts summarized by MarketBeat.

The valuation reflects these loss expectations, as Stem, Inc. currently shows a price-to-earnings ratio of minus 0.54, meaning the traditional P/E metric is not directly comparable with profitable companies and reinforcing the view that the investment case hinges on future profitability rather than current earnings power, according to data cited by MarketBeat.

Stock performance and upcoming earnings date

Stem stock has moved sharply lower over 2026, with the shares down 69.4% year to date as of September 18, 2026 compared to the USD 15.09 level at the start of the year, a performance that stands out relative to the broader market and indicates that investors are assigning a significant discount until clearer progress on profitability and revenue growth appears, based on figures compiled by MarketBeat.

Looking ahead, the next earnings checkpoint is already on the calendar, with the upcoming results date estimated for October 28, 2026, giving investors a concrete timeline to reassess Stem, Inc. stock in light of whether the company can deliver improved revenue trends and a smaller loss per share relative to the August 12, 2026 quarter, as indicated by the company calendar data summarized by MarketBeat.
