Kulicke And Soffa's Whisper Tops Guidance As Battered Stock Tests The FY27 Upturn Story

Kulicke and Soffa heads into its fiscal fourth-quarter report with an odd split personality. The business has been accelerating for four straight quarters, management has raised its outlook on every call, and purchase orders now stretch into the middle of fiscal 2027. Yet the stock has fallen 22% since the last report, lagging the S&P 500 by more than 19 points. That gap makes Wednesday's release, due after the close on November 18, less a test of whether the September quarter was good and more a test of whether the market's skepticism about the durability of this upturn is warranted.

The Street expects non-GAAP earnings of $1.44 per share on revenue of $375 million. Both figures sit almost exactly at the midpoint of management's guidance of $1.28 to $1.56 and $355 million to $395 million, so consensus is not asking for heroics. The revenue estimate implies growth of roughly 111% from the $177.6 million reported a year ago and about 13.5% sequential growth from last quarter's $330.4 million, when earnings came in at $1.07. The Earnings Whisper of $1.61, however, sits above the top of the guided EPS range, a sign that the more aggressive corner of the market expects another meaningful beat rather than a simple delivery on plan.

That expectation is rooted in management's track record over the past year. Guided EPS climbed from $0.33 to $0.67 to $1.00 and then to $1.42 for this quarter, and revenue has repeatedly landed ahead of the trajectory management laid out. The engine last quarter was general semiconductor, which jumped more than 50% sequentially, while China utilization pushed above 95%. Continued strength there would validate the claim that demand is improving faster than expected. Margins are the second check: management guided gross margin to about 48% after delivering 47.8%, up from a 45.7% trough a year ago. A print at or above that level, despite acknowledged supply-chain constraints during the ramp, would show pricing and mix are holding. Operating expenses were guided to roughly $87.5 million, inflated by incentive compensation accruals, so a modest overshoot there would be less worrying than any slippage in gross margin.

The bigger questions concern fiscal 2027. Management said its thermocompression business would exceed its $100 million fiscal 2026 target and put a $150 million to $200 million figure on next year. Investors should want confirmation that the full-year number cleared the bar, plus evidence that the FY27 range is holding or rising. Progress on the hybrid bonding tool slated to ship in the first half of fiscal 2027, panel-level packaging engagements, and the early recovery in auto and industrial wedge bonding would all reinforce the idea that this is a broadening upturn rather than a single-segment surge. The guidance for the December quarter matters most; a flat or down sequential outlook would clash with management's description of a strong first half of fiscal 2027 and the unusually long order visibility it cited.

Sentiment has swung from mildly bearish ahead of the last report to mildly bullish now, but the tape tells a more cautious story. At $69.70, shares sit well below the 200-day moving average of $86.66 and in the lower part of the post-earnings range between $56.90 and $103.39, a range that sits entirely beneath much of the prior quarter's $81.74 to $135.80 band. The unresolved CEO search, with Lester Wong still serving as interim CEO and CFO, adds a governance overhang.

Ultimately, the September quarter itself looks well telegraphed. What will determine whether the narrative stays intact is whether management can pair a solid beat with a December-quarter outlook and fiscal 2027 commentary that prove the order book is as deep as last quarter suggested.
