Balance sheet — capital structure as of FY 2024 year-end + Q4 2025 exit context

As of: 2026-04-29. FY 2024 balance-sheet anchor data is from the FY 2024 20-F (filed 2025-04-30, accession 0001178913-25-001537). Q4 2025 exit balance-sheet detail is partially captured from the Q4 2025 6-K release; full FY 2025 audited balance sheet awaits the FY 2025 20-F (expected April-May 2026).

1. Cash + investments — $1.22B at FY 2024 YE; the post-Intel-fee balance

The Intel termination fee anchor. The $1.22B FY 2024 cash + deposits balance is the post-Intel-deal-collapse baseline. Intel paid Tower a $353M termination fee in August 2023 (EE Times ✓) following the Aug 16 2023 mutual termination of the $5.4B acquisition agreement (Tower press release ✓). The fee was paid in cash and recorded as other income in FY 2023 — inflating FY 2023 net profit to $519M (vs ~$166M operating-business net profit). FY 2024 cash + deposits is roughly flat YoY because Tower simultaneously deployed approximately $432M in capex against $449M in operating cash flow + balance-sheet rebalance.

Cash management posture: Tower has historically held excess liquidity (cash + deposits well above operating-cycle requirements), which provides:

  • Capacity to self-fund the $920M SiPh/SiGe capacity commitment over 2025-2028 without significant external financing
  • Flexibility on M&A — though Tower has been M&A-quiet since the Intel-deal-collapse cycle
  • Cushion against Israel-geopolitical-risk events that might disrupt operating cash flows

FY 2025 exit cash position: Not directly disclosed in the Q4 2025 6-K release (extraction blocked). Triangulating from FY 2025 OCF $395M − Capex $437M − Debt payments $33M = net cash burn of ~$75M, plus $105M Fab 3 lease prepayment (one-off) + miscellaneous WC moves, implies end-FY 2025 cash + deposits in the ~$1.0-1.1B range ⚠. Direct extraction queued for FY 2025 20-F.

2. Debt stack — minimal; $180.8M total

Debt structure detail:

  • Tower’s debt is comprised primarily of legacy structured debt related to historical Bank of Hapoalim / Israeli bank facilities, plus a small revolving-credit component
  • Annual debt amortization runs ~$32-33M per year per the FY 2024 and FY 2025 cash-flow statements ($32M FY 2024; $33M FY 2025)
  • Net interest expense is minimal — Tower runs near-zero net debt (cash + deposits ~$1.22B vs total debt $180.8M = net cash of ~$1.04B at FY 2024 YE)

Capital-structure read. Tower at $1.04B net cash on a $21.4B market cap (current price $191.54 × 111.76M shares) represents ~5% of market cap as net cash — a modest cushion but not a defining feature at current valuation. Compare to GlobalFoundries, which is net cash ~$2.8B on a $33.1B mkt cap (~8.5%). Tower’s capital structure is strategically clean — no near-term refinancing wall, low interest expense, no covenant stress — but the cash cushion is modest relative to the $920M committed SiPh/SiGe capex envelope that Tower has announced through 2028. The forward-cash-flow tension is real and is the load-bearing balance-sheet item to watch through 2026-2027.

3. Property, plant and equipment — ~$1.29B carrying value

Total non-current operating assets~1,294~1,163

Source: FY 2024 20-F balance sheet; aggregator triangulation StockAnalysis ◐.

PP&E increased $131M YoY from $1,156M → $1,287M, reflecting:

  • $432M FY 2024 capex
  • ~$300M depreciation ⚠ (estimated from cash-flow non-cash add-backs; precise figure requires Note 13 extraction)
  • Net: ~$132M PP&E build = capex (432) − depreciation (~300) ≈ +$130M, matching the YoY delta

The $920M SiPh/SiGe capex envelope is roughly equal to FY 2024 PP&E. This is the structural capex commitment that defines the FY 2025-2028 balance-sheet trajectory. By the end of 2028, Tower’s PP&E should approach ~$2.0-2.2B (current $1.29B + new SiPh capacity + Agrate ramp + maintenance, less accumulated depreciation).

Goodwill is minimal at $7M — Tower has been M&A-quiet for the past decade (the most recent material transaction was the Maxim 8” fab acquisition in 2016 for ~$70M). The Newport Beach Fab 9 (acquired from Maxim/ADI) appears in PP&E rather than as goodwill, consistent with the asset-purchase structure.

Operating cash flow trajectory:

  • FY 2023 OCF: ~$498M ⚠ (inflated by Intel-fee partial recognition timing)
  • FY 2024 OCF: $449M ✓
  • FY 2025 OCF: $395M ✓ (depressed by $105M Fab 3 lease prepayment; adjusted: ~$500M)

OCF read. Tower’s normalized operating cash flow is ~$450-500M annually at current revenue scale. As FY 2026-2028 revenue ramps toward $2.84B target, OCF should scale roughly proportionally — implying ~$800M+ FY 2028 OCF at the ~31% target operating margin. That’s the cash-generation engine that funds the back-loaded portion of the $920M SiPh/SiGe envelope.

5. Capex run-rate analysis

FY 2028 implied~$300-400M ⚠~12-15%Reverts toward maintenance levels post-SiPh-buildout

The $920M SiPh/SiGe commitment announced at Q4 2025 release breaks down as:

  • Initial $650M committed at Q3 2025 release (Globe Newswire ✓)
  • Additional +$270M added at Q4 2025 release (Tower Q4 2025 release ✓)
  • ~28% has already been paid as of Q4 2025 → remaining ~$660M to be deployed 2026-2028
  • Targets December 2026 SiPho wafer-starts capacity > 5× Q4 2025 actual with >70% capacity reserved or in process of being reserved through 2028 — firmly backed with customer prepayments (TipRanks ✓)

Read on customer prepayments. The “firmly backed with customer prepayments” language is structurally important. It means hyperscaler / module-OEM customers are providing upfront cash to reserve SiPh capacity allocation — which partially funds the $660M remaining capex without Tower needing to draw down its own balance sheet or issue debt. This is a specialty-foundry capacity-reservation mechanism comparable to TSMC’s CapEx-Sharing Agreements with Apple/Nvidia and GFS’s Long-Term Agreements with single-sourced customers. Tower’s cash-flow tension during the FY 2026 capex peak is materially lower than the headline $700-900M run-rate suggests.

6. Equity structure

Ordinary shares outstanding:

  • 111,761,036 ordinary shares as of FY 2024 20-F cover page (Dec 31 2024) ✓ — anchor data
  • Triangulated from FY 2025 EPS data: ~112-113M average basic shares; ~114M average diluted — implying modest ~1-2M dilution per year from employee equity-plan awards

Total equity:

  • 2024-12-31: $2,662M ✓
  • 2023-12-31: $2,427M ✓
  • $235M YoY equity build = $208M FY 2024 net profit + ~$27M other comprehensive income / equity-plan additions

Book value per share:

  • 2024-12-31: $2,662M / 111.76M shares = $23.82 per share
  • Current spot $191.54 / book value $23.82 = ~8× P/B (high — reflects the SiPh growth-narrative premium)

No dividend policy. Tower has not paid dividends since its IPO. Capital allocation has been 100% reinvestment into capex + balance-sheet liquidity. No buyback program is in place as of FY 2024 20-F filing — though the post-Intel-deal-collapse $1.2B+ cash position has historically been “available for opportunistic returns” per management commentary.

Capital-returns posture. Tower’s near-term capital allocation is fully committed to the SiPh/SiGe ramp through 2028. A buyback or dividend authorization is unlikely until the FY 2026 capex peak passes — earliest probable window is FY 2027 H2 / FY 2028 as cash flow ramps to $800M+ and capex normalizes back toward maintenance levels. The ~$1B cash cushion is functionally strategic-flexibility capital, not capital-returns capital.

7. Off-balance-sheet / commitments

  • Tower-ST Agrate joint venture — Tower owns a minority share in the 300mm Lombardy facility with STMicroelectronics. The Q4 2024 6-K notes Tower began absorbing its portion of incremental Agrate operating costs — implying ongoing equity-method or proportional-consolidation accounting that flows through to operating profit.
  • TPSCo Japan joint venture — Tower-Nuvoton operating entity covering the Uozu (200mm) and Arai (300mm) sites in Japan.
  • Customer-capacity-reservation prepayments — disclosed only qualitatively (“firmly backed with customer prepayments”) at Q4 2025 release; the dollar quantum is not disclosed but is implicitly material given the 70%+ reserved capacity through 2028. TODO ⚠ for FY 2025 20-F extraction of deferred-revenue line item.
  • Israeli government grants — Tower has historically received Israeli Investment Center / Israel Innovation Authority grants for fab expansion. The grants flow through balance sheet as deferred income recognized into the P&L over the life of the supported assets. TODO ⚠ for FY 2024 20-F extraction of deferred-grant-income disclosure.

8. Subsequent events (post 2024-12-31, applicable to FY 2025 + early 2026)

  • Q1-Q4 2025 quarterly results as documented in quarterly trend — full-year revenue $1,566M, net income $220M, EPS $1.97 basic / $1.94 diluted, FY 2025 capex $437M.
  • November 2025 — Tower announced +$300M addition to the SiPh/SiGe expansion plan + new CPO foundry technology platform (GlobeNewswire 2025-11-12 ✓).
  • February 2026 — Q4 2025 release expanded the SiPh/SiGe envelope to $920M total with the additional $270M increment, and announced the $105M Fab 3 (Newport Beach) lease prepayment that depressed Q4 2025 OCF.
  • March 11 2026 — LWLG-Tower development agreement announced for EO-polymer modulator integration on PH18 PDK (StockTitan ✓) — strategic but not yet revenue-material.
  • Q1 2026 print scheduled for 2026-05-13 (Globe and Mail ✓).
  • FY 2025 20-F filing expected April-May 2026 — will provide audited full-year balance sheet and customer-prepayment / deferred-revenue dollar quantum.
