Tower Semiconductor (TSEM) Q2 2026 — Q2 2026, quarter ended June 30. Revenue $460.1M, +23.7% YoY, vs ~$463.8M consensus (a MISS). GAAP EPS $0.80 basic / $0.79 diluted; adjusted diluted $0.88 vs $0.77. Gross margin 29.9% from 21.5%. Operating profit $90.3M, 2.26x. Q3 guide $520M, a record. TSEM closed $239.53, +2.2%. Tower posted its best quarter ever and guided to a record. Then we split the revenue line in two. Silicon photonics went from a $180M annual run rate to $680M - about +$125M in the quarter. Total revenue grew $88.0M. So everything else Tower makes shrank ~$37M, roughly 11% YoY. Record profit also came with NEGATIVE free cash flow (-$9.6M), and 84% of this year's net-cash build is customer prepayments, not earnings. THE CALL: AVOID (4/5, A REAL INFLECTION, AT A PRICE THAT ALREADY ASSUMES IT WORKED) — base-case value ~$160.0 vs ~$239.53 today. KEY METRICS: - CALL: AVOID 4/5, fair value ~$160 vs $239.53 - about 33% BELOW the price. Owner-earnings DCF charging the FULL capital budget, expensing stock comp, 15% cash tax (Pillar Two ends Israel's 7.5% preferred rate), net cash added back at $1.018B after removing $321M of customers' advances, over 114.4M diluted ORDINARY shares. At 10%: bear $80, base $144, bull $200. NONE of the nine grid cells reaches $239.53. Reverse-DCF: today's price requires a SUSTAINED ~63% gross margin. Tower earned 29.9%; TSMC ~59%; UMC ~30%. - THE RECORD IS ONE PRODUCT LINE. SiPho ran at a $680M annual rate in Q2-26 (~$170M in the quarter) vs $180M a year ago (~$45M) - up ~$125M. TOTAL revenue rose $88.0M, $372.1M to $460.1M. So everything else - RF/SiGe, power BCD, image sensors, MEMS, displays - went from ~$327M to ~$290M, DOWN ~11% YoY. SiPho is now ~37% of revenue, from ~12%. Management targets a $1B SiPho run rate in Q4-26 and raised the 2028 model to $3.6B revenue / $1.2B net profit. - THE MARGIN GAIN IS MIX, NOT LOADING - the best fact in the bull case. Gross profit rose $57.7M ($80.0M to $137.8M, +72%) on $88.0M more revenue = a 65.6% incremental gross margin. Charge the legacy book's -$37M at a 20% contribution margin and SiPho added ~$65M of gross profit on ~$125M of revenue - a ~52% incremental gross margin. Absorption reverses; mix sticks. P&L: COGS $322.3M, R&D $23.6M, MG&A $23.9M, operating profit $90.3M (19.6%), tax 14.7%, net attributable $90.8M. - RECORD PROFIT, NEGATIVE FREE CASH FLOW. Q2 operating cash flow $177.0M less $186.6M capex = -$9.6M. Capex ran 2.23x the $83.6M of D&A. The half-year looks better ($686.9M vs $343.0M) but $282.6M of it is CUSTOMERS' ADVANCES; strip them and H1 FCF is $61M against $155.8M of net profit. Net cash $1.340B rose $349M this year while customer advances rose $294M - 84% of the build is prepayments. - WHAT THE FILING SAYS QUIETLY. 'Record operating profit (excluding non-recurring items)' excludes Intel's $353M break fee from the collapsed $5.4B takeover. Risk factor (xxxvii) discloses Intel's determination NOT to perform the capacity-corridor deal - the $300M New Mexico 300mm arrangement is in mediation; Tower's US path is replaced by Japan (new fab beside Fab 7, Arai, METI grants) and shared Agrate with STMicro. Cross-check needing no forecast: 8.81x book ($3.071B equity) on a trailing ROE of 11.8% implies a sustainable ROE near 65%; TSMC earns ~35%. FOREIGN ISSUER: reports in USD (no FX) and lists ORDINARY SHARES, not ADSs. What to watch: Changes our mind UP: the non-photonics book growing again for two straight quarters, FCF positive after capex with advances stripped out, or gross margin through 35%. Confirms the bear: legacy still shrinking at year-end, or advances falling while growth slows. We would start looking near $160.
