ChargePoint Stock Ripped 83% Higher in September. Is It a Buy?

ChargePoint shares surged 83.3% in September, including a 75% single-session jump after its fiscal Q2 2027 report: revenue rose 18% to $116.1 million, gross margin increased to 36% from 31% a year earlier, and net loss nearly halved to $35.6 million. Heavy short interest helped amplify the rally, while the company cited new products, fleet partnerships and AI initiatives as growth drivers. The outlook remains uncertain: ChargePoint expects only 4% revenue growth at the midpoint for Q3, and part of the margin improvement came from one-time tariff refunds.

Analysis

The key distinction is between a liquidity-driven rerating and a durable earnings inflection. A squeeze can keep CHPT dislocated from fundamentals for days or weeks; it does not validate the margin trajectory. The relevant test over the next 1–3 months is whether gross margin holds after tariff refunds are excluded and whether revenue outperforms the modest near-term outlook without renewed cash deterioration. If not, the rally has little operating evidence behind it to support a lasting multiple expansion.

The second-order risk is that EV-charging competition remains a utilization and price-per-port problem: low network usage and aggressive pricing can limit returns even as deployments and product shipments rise. This pressures charging-network peers as well as CHPT; it may also make automakers and fleet operators more selective about partner economics. The Mercedes-Benz relationship is strategically useful validation, but absent disclosed scale or economics it should not be treated as material revenue support for either CHPT or Mercedes-Benz Group AG (MBG).

Over 6–18 months, sustained software adoption and lower operating costs could improve the model, but management’s AI claims are not yet a measurable earnings catalyst. The contrarian risk to an outright bearish stance is that improved cost control plus limited float/short positioning can produce further sharp upside before fundamentals catch up. Avoid chasing either direction until the squeeze effect and ex-refund margins are clearer.

Key Decisions for Investors

• Do not initiate a directional CHPT position solely on the squeeze or management’s AI commentary. Treat the next earnings release as the confirmation point; verify gross margin excluding tariff refunds, cash usage, and revenue versus guidance.
• For a bearish expression, wait for momentum and borrow conditions to normalize, then consider a defined-risk CHPT put spread rather than an uncapped short. The setup is invalidated by sustained ex-refund margin improvement alongside revenue acceleration and better cash performance.
• Monitor CHPT’s disclosed fleet and product deployments for conversion into recurring revenue and utilization—not just shipment or partnership announcements. Lack of quantified economics leaves the MBG partnership as a watch item, not a basis for an MBG trade.
• Reassess over the next 1–3 months: a margin reversal or weaker outlook would support a post-squeeze fade; durable margin gains and cash stabilization would argue against it.
