Vishay (VSH) Q1 2026 earnings review
Vishay 3.0 Strategy Triggers Breakout, But Cash Burn Persists
Vishay delivered a breakout quarter that forcefully validates management's 'Vishay 3.0' capacity expansion strategy. Revenue accelerated 17% YoY to $839.2M, beating the steady mid-$700M run rate of 2025. More importantly, gross margin broke out of its 19% rut, reversing upward to 21.0% as the dilutive drag from the Newport fab appears to be fading. Forward indicators are flashing bright green: the total book-to-bill ratio surged to 1.34 (and a massive 1.47 in Semiconductors), pushing backlog to 5.7 months. Guidance for 26Q2 implies further acceleration to $890M in revenue and 22.0% gross margins. However, aggressive CapEx ($110.7M in the quarter) is keeping Free Cash Flow deeply negative (-$46.9M), requiring investors to fund the growth cycle with increasing debt.
🐂 Bull Case
A book-to-bill ratio of 1.34 across the board, with semiconductors hitting 1.47, is exceptional. With backlog stretching to 5.7 months, the company has locked in highly visible revenue for the remainder of the fiscal year.
After a grueling year of the Newport fab depressing margins by 150-200 bps, consolidated gross margin finally expanded 200 bps YoY to 21.0%. The 22.0% guidance for 26Q2 signals strong operational leverage is kicking in.
🐻 Bear Case
The multi-year capacity buildout is expensive. Capital expenditures of $110.7M in Q1 drove Free Cash Flow to negative $46.9M, forcing management to draw $31M from its revolving credit facility. Shareholder returns remain constrained.
Total inventories grew by $31M sequentially to $790.8M. While partially justified by surging backlog, the build-up of raw materials and work-in-process limits working capital efficiency.
⚖️ Verdict: 🟢
Bullish. Management promised that heavy investments in 2024-2025 would position Vishay for the next market upcycle. A 17% revenue growth, expanding margins, and an explosive book-to-bill ratio prove the strategy is actively taking market share.
Key Themes
Book-to-Bill and Backlog Surging
The most powerful data point in the release is the forward-looking demand. The book-to-bill ratio accelerated dramatically from 1.20 in 25Q4 to 1.34 in 26Q1. Semiconductors led the charge at 1.47, and Passives came in strong at 1.23. The backlog has now expanded to 5.7 months (up from 4.9 months in 25Q4), virtually guaranteeing revenue outperformance in H2 2026.
Vishay 3.0 Capacity Expanding Market Share
CEO Joel Smejkal stated that because of aggressive capacity investments, 'Vishay is reliably scaling with our customers.' This was a central thesis in 2025 calls—sacrificing short-term cash to be the only supplier with inventory when the cycle turned. The 17.3% YoY revenue growth confirms Vishay is capturing share in a market upcycle.
Newport Fab Reversing from Drag to Driver
Throughout 2025, the Newport SiC fab ramp was a structural headwind, dragging gross margins down by 130-200 bps quarterly. Management guided in 25Q4 that Newport would become gross profit neutral by the end of 26Q1. The 140 bps sequential margin expansion (19.6% to 21.0%) and the 22.0% Q2 guidance strongly imply this headwind has been neutralized and is now turning accretive.
Sustained Negative Free Cash Flow
The operational triumph is masked by a poor cash profile. Q1 26 Free Cash Flow came in at -$46.9M. The company spent $110.7M on CapEx, effectively wiping out the $63.7M generated from operations. Vishay continues to fund this shortfall via debt, drawing down a net $31M on its revolving credit facility in Q1.
Working Capital: Inventory Accumulation
Despite the massive 17% YoY sales surge, total inventories increased sequentially from $759.2M to $790.8M. The build was broad-based across raw materials (+$15.2M) and work-in-process (+$16.6M). While management wants to 'ensure competitive lead times,' rising inventories amidst booming sales suggests working capital efficiency is deteriorating.
Macro Cycle Risk: The Double-Ordering Ghost
A semiconductor book-to-bill ratio of 1.47 is astronomically high. While AI and smart grid demand are real, historical component cycles suggest that numbers this high often contain 'panic buying' or double-ordering from EMS providers attempting to front-run lengthening lead times. If consumption doesn't match this order velocity, cancellations could plague late 2026/early 2027.
Other KPIs
Accelerating. Up significantly from 1.8% in the prior quarter and a near-breakeven 0.1% a year ago. SG&A expenses rose to $154.5M (up from $142M in 25Q4), driven by incentive compensation, but operating leverage from the $839M top line allowed margins to expand.
Accelerating. EBITDA reached $78.0M, compared to $54.5M (7.6% margin) in Q1 25. This 170 bps YoY improvement demonstrates the underlying cash profitability of the business before the heavy depreciation ($58.2M) of the new capacity investments is factored in.
Guidance
Accelerating. The midpoint of $890M implies an explosive 16.8% YoY growth compared to 25Q2 ($762.3M) and a 6.0% sequential increase. This confirms the market upcycle and proves the backlog is actively converting to revenue.
Accelerating. Moving up a full 100 basis points sequentially from 21.0% in Q1. This indicates that pricing power is holding and the massive capacity investments are finally driving volume efficiencies rather than underutilization penalties.
Key Questions
CapEx Peak and FCF Inflection
CapEx ran at $110.7M in Q1, driving negative FCF. At what quarter in FY26 do you anticipate capital expenditures normalizing, and when will Free Cash Flow structurally return to positive territory?
Double Ordering Dynamics
A 1.47 book-to-bill in semiconductors is exceptionally high. How much of this order intake do you attribute to fundamental demand (like AI power and smart grids) versus customers double-ordering to secure capacity ahead of lengthening lead times?
Newport Fab Margin Contribution
With Q2 gross margin guided to 22.0%, has the Newport fab officially crossed the threshold from being a margin dilutive drag to being gross profit accretive, as targeted in the Q4 call?
