The fight is over a number the press release buried: 11.8 weeks of chips sitting in the sales channel, against data-center revenue that arrives in 2027 and later. [Power Integrations](https://theinference.org/markets/companies/power-integrations) beat its own profit line and the market sold it anyway. The San Jose maker of high-voltage power-conversion chips [reported Q3 non-GAAP earnings of $0.46 a share on November 4](https://finance.yahoo.com/markets/stocks/articles/power-integrations-reports-third-quarter-210100743.html), $0.05 above consensus, on revenue of $125.47 million that came in a hair under estimates [1][2]. The next day, [a sector-wide rout of AI-adjacent chip names](https://news.alphastreet.com/power-integrations-plunges-15-3-amid-sector-wide-selling/) took the stock down 15.3% to $39.64, cutting its market value to $2.2 billion, part of a selloff that knocked seven peers down between 7.7% and 18.5% [5]. Two brokers cut price targets in the week with no offsetting upgrades [5]. ## The number the wire stories skipped [The earnings-call transcript](https://www.tradingkey.com/news/transcripts/262289099-) holds the figure that decides this trade: channel inventory, the unsold chips sitting with distributors and end customers. It jumped 4.5 weeks in one quarter, from 7.3 weeks to 11.8, against the company's own 8-week target [3]. CFO [Nancy Erba](https://theinference.org/markets/people/nancy-erba) split the build three ways. Weak Chinese appliance sell-through needs one to two quarters to clear, delayed metering projects in India need two to three, and a newer, less predictable driver has appeared: end customers ordering buffer stock because they see shortages elsewhere in the supply chain [3]. Management conceded the glut could sit at 9 to 10 weeks through 2027 [3]. *Chart: **Channel inventory sits at 11.8 weeks against an 8-week target** Column chart of Power Integrations channel inventory in weeks: 7.3 in Q2 2026 rising to 11.8 in Q3 2026 against an 8-week company target, with a ~9.5-week management estimate into 2027* *Channel inventory in weeks of supply, distributor and end-customer stock; the 2027 bar is management's stated 9-10 week scenario, midpoint, not a quarterly reading. Source: TradingKey Q3 2026 earnings call transcript, 6 Nov 2026. [3]* ## Where the money is dated The bull case is real, but its revenue arrives in 2027-2029 while the inventory cost lands this quarter [3]. The data-center pipeline more than tripled since the start of 2026; four 800-volt socket design-ins, sockets reserved in a customer's product design, enter production in 2027 [3]. Gallium nitride (GaN), the wide-bandgap chip material that switches power more efficiently than silicon, drove record revenue on track for 2026 [3]. The 1,250-volt GaN line for main power paths samples in 2027 and rolls out in 2028-29 [3]. [The solid-state circuit-breaker project with Ideal Power](https://www.pbsionthenet.net/article/224898/Power-Integrations-and-Ideal-Power-collaborate-on-efficient--always-on-solid-state-circuit-breakers-for-800VDC-AI-data-centres.aspx), pairing Power Integrations' 1,700-volt InnoMux chip with Ideal Power's B-TRAN bidirectional switch, is at early prototype stage [6]. ## What the record prices *Chart: **Revenue recovered through 2026 to a $125.47M quarterly high** Line chart of Power Integrations quarterly revenue from Q4 2023 to Q3 2026, $89.5 million to $125.5 million, with a dip to $103.2 million in Q4 2025* *Quarterly net revenue in millions of dollars, from Power Integrations' SEC filings, retrieved 8 Nov 2026. Source: Power Integrations quarterly figures from its SEC filings. [2][8]* Revenue recovered through 2026 to a $125.5 million high, with Q4 2025 the one dip, and [gross margin reached 55.2%](https://www.sec.gov/Archives/edgar/data/833640/000083364026000156/0000833640-26-000156-index.htm) [3][7]. The bulls' exhibits: $37 million of quarterly free cash flow, $288 million of cash and investments, and a dividend rising to $0.22 a share for 2027 [2][3]. The bears' exhibits: consumer, a third of sales, fell 7% sequentially on appliance weakness tied to housing and tariff-inflated prices, and the Q4 revenue guide of $118-126 million sits below the $124.4 million consensus [3][1]. [Needham cut its target to $65 from $80 yet kept Buy](https://www.streetinsider.com/Analyst+Comments/Power+Integrations+%28POWI%29+PT+Lowered+to+%2465+at+Needham/27293959.html), arguing the inventory build is nuanced rather than broad demand deterioration [4]. At $39.64, buyers are betting the channel clears faster than management's 9-to-10-week scenario; sellers are betting buffer stock unwinds into 2027. Both sides wait on the same readings: quarterly channel weeks, appliance sell-through, and the Indian metering ramp. ## What to watch The Investor Day on March 8, 2027, carries the plan to double the serviceable available market (SAM), the revenue the company can currently compete for [3]. Until then, the tell is simple: whether channel weeks fall toward 8 or stick at 9 to 10 [3]. ## Takeaway Power Integrations beat on profit but sits on 11.8 weeks of channel inventory against an 8-week target; whether those weeks fall toward 8 or stick at 9-10 through 2027 decides the trade at $39.64. ## Sources 1.
