$PDFS for the current environment of trying to figure out if you investment is at risk from AI, or a beneficiary of AI. Would love to here any feedback, pro or con. PDF Solutions (PDFS) — 2‑Page Institutional Memo AI‑Resilient Semiconductor Infrastructure with Multi‑Year Visibility February 14, 2026 • Price: $33.69 • Market Cap: ~$1.38B I. Investment Thesis The dominant fear in software today is: “What if AI replaces this company.” PDF Solutions is one of the few companies where the opposite is true: AI increases the company’s relevance, revenue, and strategic necessity. PDFS owns the physics‑validated, cross‑tool, cross‑fab semantic layer required for AI to operate safely inside semiconductor manufacturing. LLMs can generate text; they cannot infer nanometer‑scale physical behavior. As fabs deploy AI agents across inspection, metrology, test, and tool control, PDFS becomes the context engine that prevents hallucinations, aligns heterogeneous data, and enables AI to reason about the physical world. With 94% recurring revenue, 77% gross margins, and a multi‑year eProbe expansion cycle, PDFS is positioned for a structural re‑rating as investors recognize it as a semiconductor AI infrastructure platform, not a legacy yield‑analytics vendor. II. Why AI Cannot Disrupt PDFS 1. The 30‑Year Switzerland Effect PDFS has been the neutral, vendor‑agnostic data steward of the semiconductor industry for three decades. This neutrality is a structural moat: • OEMs trust PDFS because it does not compete with them • Fabs trust PDFS because it does not privilege any tool vendor • Governments and hyperscalers trust PDFS because it has never violated data boundaries This is why PDFS is allowed inside the most sensitive data flows in the world — and why no AI model or OEM‑owned analytics platform can replicate that trust. 2. AI Cannot Replace Physics Semiconductor manufacturing is deterministic. A 3nm process window cannot be “predicted” by a language model. PDFS’s models are built from 30 years of wafer, tool, and defect data — the causal, physics‑grounded context AI cannot generate. 3. AI Has No Access to Fab Data Public models have zero visibility into the petabytes of proprietary sensor data behind SecureWISE. PDFS is the only company with: • cross‑tool data normalization • cross‑fab semantic alignment • decades of labeled defectivity and electrical signatures This dataset cannot be recreated, purchased, or reverse‑engineered. 4. SecureWISE: The Toll Collector for Fab‑Wide AI SecureWISE is installed in 99% of 300mm fabs and functions as the mandatory, vendor‑agnostic data highway connecting OEM tools, fab systems, and analytics platforms. PDFS’s thirty years of neutrality made them the perfect steward of SecureWISE (acquired in 2025) — the only entity OEMs and fabs were willing to trust as the neutral data intermediary. As fabs deploy AI agents across the factory, every inference, model update, and cross‑tool correlation must pass through SecureWISE. This creates a toll‑collector model with multi‑year visibility. III. Platform Transformation: Sapience Hub & Exensio AI Studio PDFS is transitioning from fab‑local analytics to a cloud‑native, enterprise‑wide semiconductor data‑analysis platform and AI enablement layer. Sapience Manufacturing Hub The cloud‑native evolution of Exensio, unifying data across: • MES • ERP • inline inspection • metrology • test • assembly • IIoT sensor networks Why Sapience Matters • AI‑ready, physics‑validated semantic layer • Cross‑enterprise normalization (fabs, OSATs, OEMs, supply chain) • No‑code/low‑code extensibility • Expands TAM by ~10× • Establishes the enterprise data foundation for AI‑native manufacturing Exensio AI Studio The AI application layer enabling fabs and OEMs to build, validate, and deploy models on top of PDFS’s physics‑validated data. Key Capabilities • Model training and validation • Physics‑grounded feature engineering • Cross‑tool correlation for drift detection • Inline + test‑floor inference pipelines • Automated deployment workflows • Model‑driven digital‑twin workflows for scenario analysis and predictive optimization Why Studio Matters • AI cannot operate safely without context — Studio provides it • OEMs are embedding Studio into tool‑side analytics • Accelerates time‑to‑value; reduces reliance on internal data science teams • Subscription‑based → expands recurring revenue • Completes the platform stack IV. Key Drivers (2026–2028) 1. Sapience & Studio Adoption Primary growth engines, expanding PDFS into enterprise‑wide, AI‑ready data infrastructure. 2. SecureWISE Distribution Monopoly • Installed in 99% of 300mm fabs • Only secure, vendor‑agnostic data pipe • Recent eight‑figure OEM contracts confirm SecureWISE as mandatory AI infrastructure 3. eProbe / DRAM Inflection • eProbe fleet expected to nearly double in 2026 • 2026 revenue units driven primarily by logic customers • HBM pilots convert in 2H26 → 2027 revenue tailwind • Each unit generates multi‑year subscription revenue with expanding data annuities 4. The “Masked Growth” Reveal • Recurring revenue: 94% • Core analytics CAGR since 2020: 20%+ • Gainshare volatility eliminated → true growth profile emerges V. Financial Profile (Q4‑Verified Rule‑of‑40 Delivery) PDFS delivered one of the strongest Rule‑of‑40 quarters in semiconductor software. Q4 2025 Actuals • 25% revenue growth • 24% non‑GAAP operating margin • 77% non‑GAAP gross margin • 94% recurring revenue • Record quarterly revenue: $62.4M Rule‑of‑40 Score 25 + 24 = 49 Durable because: 94% recurring revenue SecureWISE and eProbe subscriptions are multi‑year OEM integrations create non‑discretionary revenue AI adoption increases data volume and dependence on PDFS’s semantic layer eProbe adoption just beginning to inflect upward VI. Valuation: Probability‑Weighted Scenarios (12–18 Months) Bull Case (30%) — PT $95 (12× EV/S) Recurring mix approaches 95%, eProbe fleet doubles, margins expand toward 27%, Sapience/Studio adoption accelerates. Base Case (55%) — PT $65 (8× EV/S) Market recognizes PDFS as a vertical SaaS + semiconductor data‑infrastructure platform with 20%+ growth and elite margins. Bear Case (15%) — PT $40 (5× EV/S) Growth slows to mid‑teens, OEM adoption lags, market remains anchored to legacy perceptions. VII. Conclusion In a market where AI is eroding software moats, PDF Solutions is one of the few companies whose relevance increases as AI adoption increases. PDFS owns the physics‑validated semantic layer — SecureWISE, Sapience Hub, Exensio, and Exensio Studio AI — that makes AI safe, accurate, and actionable inside semiconductor manufacturing. The market still values PDFS like a legacy yield vendor at 4× EV/S. As the logic‑driven eProbe ramp, HBM pilot conversions, Sapience deployments, Studio adoption, and margin expansion become visible in 2026, that legacy multiple breaks — and the re‑rating begins.

$PDFS The Best Way to Increase Near‑Term Capacity in the Memory Market Is to Increase Yield Thesis The memory industry is entering what analysts are calling “RAMageddon”—a structural, multi‑year supply crisis driven by unprecedented HBM demand from AI infrastructure. Physical capacity additions (new fabs, TSV lines, packaging, substrates) require 18–36 months to materially increase output. With all major suppliers sold out through 2026–2027, the only lever capable of increasing near‑term effective capacity is yield improvement. PDF Solutions (PDFS), the industry’s most experienced independent yield‑improvement platform, is uniquely positioned to benefit from this dynamic. 1. RAMageddon: HBM Capacity Cannot Scale Fast Enough AI infrastructure growth is constrained by HBM availability, not GPUs. Key structural realities: • HBM demand exceeds supply across all vendors • TSV, stacking, and packaging remain gating steps • New capacity requires long‑lead capex and supply‑chain expansion • No meaningful physical relief arrives before 2027 Conclusion: RAMageddon cannot be solved with traditional capex. Near‑term supply must come from yield. 2. Yield Is the Only Lever That Moves Near‑Term Output Yield improvement is the only mechanism that: • scales immediately • requires no new fabs or cleanroom expansion • requires only minimal incremental tooling • compounds across DRAM die, TSV, stacking, and final test • increases usable output without expanding physical footprint HBM yield is multiplicative: DRAM die × TSV × microbump × stacking × final test. Small improvements at each stage translate into double‑digit effective capacity gains. 3. PDF Solutions Has Been Helping IC Manufacturers Increase Yields for 30 Years PDF Solutions has been helping IC manufacturers increase yields for 30 years across logic and memory. Recently, this expertise has expanded into: • test • advanced packaging • 3D integration • HBM (currently in pilot with several memory manufacturers) Their platform is uniquely comprehensive: • Exensio — cross‑fab analytics spanning DRAM, TSV, stacking, and test • eProbe/DirectScan (HaaS) — inline electrical characterization currently in pilot, with conversions and deployments expected in 2H 2026 per the Feb 11, 2025 earnings call • secureWISE — the industry’s secure collaboration backbone for multi‑company yield debug PDFS’s long‑standing work in logic, DRAM, NAND, and packaging naturally extends into TSV, multi‑die stacking, and HBM — the critical bottlenecks of today’s memory market. 4. PDFS Can Unlock 10–20% More Effective HBM Output in <6 Months PDFS routinely enables: • 5–15% DRAM die yield improvement • 10–30% TSV/stacking yield improvement • 3–10% packaging/test yield improvement Because these gains multiply, not add, the combined effect is: 10–20% more effective HBM output in under six months with no new fabs or long‑lead capex This is the highest‑leverage intervention available during RAMageddon. 5. Revenue Impact for Memory Suppliers A 10–20% yield‑driven capacity uplift translates into: • SK hynix: +$3.6B to +$7.2B revenue • Micron: +$1.2B to +$2.4B revenue • Samsung: +$1.0B to +$2.0B revenue Yield improvement is a multi‑billion‑dollar unlock for each supplier. 6. PDFS Tailwind: HaaS‑Driven Revenue Expansion (2026–2028) Because eProbe/DirectScan is delivered via Hardware‑as‑a‑Service, PDFS captures recurring, high‑margin revenue as pilots convert to production deployments. Incremental revenue opportunity (2026–2028): • Base Case (2 suppliers adopt): $78M • Full Adoption (all 3 suppliers): $117M • Bull Case (HBM4 expansion): $150–220M This represents 36–101% of PDFS’s current annual revenue, driven by: • multi‑tool HaaS deployments • recurring analytics subscriptions • expansion to new HBM3E/HBM4 lines • higher tool density per line as complexity increases RAMageddon accelerates the urgency of these deployments. 7. Investment Implication If RAMageddon can only be mitigated in the short term through yield improvement—and PDF Solutions has been helping IC manufacturers increase yields for 30 years across logic and memory—then: PDF Solutions is the most direct, scalable, and immediate way to participate in the HBM supply‑chain bottleneck. PDFS is not a derivative play on memory. It is a critical‑path enabler of near‑term capacity expansion and a beneficiary of a multi‑year, high‑margin, recurring revenue tailwind as pilots convert to production in 2H 2026 and beyond.

$PDFS 📄 ONE‑PAGE INVESTOR MEMO — PDF Solutions (PDFS) Title: PDF Solutions: A Rule‑of‑40 Semiconductor Operations Platform Hidden in Plain Sight Investment Thesis PDF Solutions has completed a multi‑year transformation into the connectivity + analytics + AI + orchestration platform for semiconductor manufacturing. The Q4 call confirmed that PDFS now operates with a Rule‑of‑40 financial profile, a non‑replicable distribution moat, and recurring revenue dominance. Despite this, the market continues to value PDFS like a cyclical tools vendor, creating a multi‑year structural mispricing. Key Drivers 1. secureWISE Embedded in Cimetrix SDK (Distribution Monopoly) • secureWISE agent now ships by default on thousands of tools annually. • Installed in 99% of 300mm fabs. • No competitor has equivalent OEM + fab penetration. • This is the deepest, most durable moat in the semiconductor software ecosystem. 2. Recurring Revenue Dominance • Recurring revenue: $205M, +41% YoY. • Driven by secureWISE usage, Cimetrix runtime, and eProbe subscription. • Gainshare is effectively retired (one customer left). • Revenue mix now resembles a SaaS platform, not a tools vendor. 3. Rule‑of‑40 Achieved (Score: 43) • Revenue growth: 22% • Operating margin: 21% • Gross margin: 76% • Operating leverage is visible and accelerating. • PDFS now qualifies for platform‑level valuation multiples. 4. High‑Visibility Growth • Backlog: $254M (2nd highest ever; Q3 peak was $292M). • 20% growth reaffirmed for 2026. • eProbe fleet doubling; all new units subscription. • Memory (DRAM) pilots → production ramp in 2026. • secureWISE + DEX integrates fabs, OEMs, OSATs, and fabless into a single data layer. Valuation • Market multiple: ~4× EV/S (mispriced as a tools vendor). • Rule‑of‑40 platform comps: 8–12× EV/S. • Fair value: $58–75/share (base). • Bull case: $85–130/share. • Platform case: $125–175/share. Conclusion PDFS is a Rule‑of‑40 compounder with a multi‑layer moat, recurring revenue dominance, and multi‑year visibility, trading at a deep discount to intrinsic value. The mispricing is structural, not temporary. This is a rare opportunity to accumulate a core position before the market re‑rates the business into the platform cohort.

Investment Implication If RAMageddon can only be mitigated in the short term through yield improvement—and PDF Solutions has been helping IC manufacturers increase yields for 30 years across logic and memory—then: PDF Solutions is the most direct, scalable, and immediate way to participate in the HBM supply‑chain bottleneck. PDFS is not a derivative play on memory. It is a critical‑path enabler of near‑term capacity expansion and a beneficiary of a multi‑year, high‑margin, recurring revenue tailwind as pilots convert to production in 2H 2026 and beyond.

$PDFS 📄 ONE‑PAGE INVESTOR MEMO — PDF Solutions (PDFS) Title: PDF Solutions: A Rule‑of‑40 Semiconductor Operations Platform Hidden in Plain Sight Investment Thesis PDF Solutions has completed a multi‑year transformation into the connectivity + analytics + AI + orchestration platform for semiconductor manufacturing. The Q4 call confirmed that PDFS now operates with a Rule‑of‑40 financial profile, a non‑replicable distribution moat, and recurring revenue dominance. Despite this, the market continues to value PDFS like a cyclical tools vendor, creating a multi‑year structural mispricing. Key Drivers 1. secureWISE Embedded in Cimetrix SDK (Distribution Monopoly) • secureWISE agent now ships by default on thousands of tools annually. • Installed in 99% of 300mm fabs. • No competitor has equivalent OEM + fab penetration. • This is the deepest, most durable moat in the semiconductor software ecosystem. 2. Recurring Revenue Dominance • Recurring revenue: $205M, +41% YoY. • Driven by secureWISE usage, Cimetrix runtime, and eProbe subscription. • Gainshare is effectively retired (one customer left). • Revenue mix now resembles a SaaS platform, not a tools vendor. 3. Rule‑of‑40 Achieved (Score: 43) • Revenue growth: 22% • Operating margin: 21% • Gross margin: 76% • Operating leverage is visible and accelerating. • PDFS now qualifies for platform‑level valuation multiples. 4. High‑Visibility Growth • Backlog: $254M (2nd highest ever; Q3 peak was $292M). • 20% growth reaffirmed for 2026. • eProbe fleet doubling; all new units subscription. • Memory (DRAM) pilots → production ramp in 2026. • secureWISE + DEX integrates fabs, OEMs, OSATs, and fabless into a single data layer. Valuation • Market multiple: ~4× EV/S (mispriced as a tools vendor). • Rule‑of‑40 platform comps: 8–12× EV/S. • Fair value: $58–75/share (base). • Bull case: $85–130/share. • Platform case: $125–175/share. Conclusion PDFS is a Rule‑of‑40 compounder with a multi‑layer moat, recurring revenue dominance, and multi‑year visibility, trading at a deep discount to intrinsic value. The mispricing is structural, not temporary. This is a rare opportunity to accumulate a core position before the market re‑rates the business into the platform cohort.

$INTC $PDFS a tangential investment. It’s the Data, Stupid An Investment Memo on PDF Solutions and the Hidden Value of Semiconductor Data Infrastructure 1. Executive Summary PDF Solutions is fundamentally mispriced because the market still views it as: • a semiconductor software vendor • a niche yield‑management tool provider • a vertical SaaS company This framing is outdated. PDF is becoming the data‑infrastructure layer of the semiconductor industry, aggregating electrical, equipment, process, yield, and lifecycle data across fabs, nodes, and customers. This data is proprietary, compounding, and irreplaceable — and it is the foundation of a platform business with network effects, switching‑cost moats, and strategic leverage. The correct thesis is simple: It’s the data, stupid. 2. Industry Context: The Semiconductor Data Problem Semiconductor manufacturing generates more data per dollar of revenue than any other industry. Yet: • data is siloed across tools, fabs, and vendors • formats are inconsistent • defectivity signatures are not shared • yield learning is slow and non‑portable • OEMs and fabs lack a unified data model This fragmentation is the single biggest bottleneck in: • yield improvement • time‑to‑ramp • advanced‑node economics • HBM stacking yields • customer qualification cycles The industry desperately needs a unified data layer. PDF is the only company positioned to provide it. 3. PDF’s Trojan Horse: DFI/eProbe as a Data Engine DFI and eProbe are misunderstood as inspection tools. They are actually data‑generation engines. Each eProbe produces: • electrical defect maps • systematic defect signatures • TSV failure patterns • die‑level electrical fingerprints • wafer‑level correlation data • cross‑layer defectivity insights This is the richest, most actionable data in the semiconductor stack. Every new eProbe installed expands PDF’s proprietary dataset and deepens customer lock‑in. This is the Trojan horse: 4. The Platform Stack: PDF’s Integrated Data Infrastructure PDF’s platform spans the entire semiconductor lifecycle: 1. Cimetrix Equipment connectivity + OEM integration. 2. secureWISE OEM ↔ fab secure data exchange. 3. Exensio Yield, defectivity, and equipment analytics. 4. DFI/eProbe Electrical defectivity data — the crown jewel. 5. Sapience Hub ERP ↔ MES ↔ fab integration. This is not a product suite. It is a vertically integrated data platform. Once a customer adopts the stack, switching becomes nearly impossible. 5. Data Gravity: The Source of PDF’s Moat Data gravity is the phenomenon where: • the more data a platform holds • the more valuable it becomes • the harder it is to move away • the more third parties integrate into it PDF benefits from data gravity in four ways: 1. Historical data Years of defectivity archives cannot be recreated. 2. Cross‑fab data Correlations across fabs, nodes, and geographies. 3. Cross‑customer data Insights from multiple leading‑edge manufacturers. 4. Electrical data DFI signatures are proprietary and uniquely valuable. This is the same dynamic that made: • Snowflake • Datadog • SAP • ServiceNow into multi‑decade compounders. PDF is building the semiconductor equivalent. 6. Intel’s Outsourcing Decision: The Breakout Moment Intel’s announcement that it is outsourcing major portions of its data management to PDF Solutions is a watershed moment. It signals: • recognition that PDF’s data model is superior • willingness to standardize on an external platform • collapse of internal resistance to DFI/eProbe • validation of PDF as a strategic infrastructure layer Intel’s 18A credibility depends on yield learning and defectivity transparency — both of which require PDF’s data. This is the first domino. 7. HBM and 3D Packaging: The Data Explosion HBM4, HBM4E, and 3D packaging create unprecedented electrical‑defectivity complexity: • more TSVs • more layers • more stacking • more hybrid bonding • more compounded yield loss This drives: • more sampling • more eProbe tools • more electrical data • more cross‑fab analytics • more reliance on PDF’s platform HBM is the largest SAM for eProbe — and the fastest‑growing. 8. The Compounding Flywheel PDF’s data advantage compounds with every new: • fab • line • tool • wafer • customer • node • OEM integration This creates a flywheel: 1. More tools deployed 2. More electrical + equipment data 3. Better analytics + defectivity models 4. Higher yield‑learning velocity 5. More fabs standardize on PDF 6. More OEMs integrate via Cimetrix/secureWISE 7. More data flows into the platform 8. Switching costs rise exponentially This is how a niche vendor becomes a strategic dependency. 9. Valuation Implications The market still values PDF like: • a semiconductor software company • a niche inspection‑tool vendor • a vertical SaaS provider But the correct comp set is: • Snowflake • Datadog • ServiceNow • Synopsys (platform side) • Cadence (data‑model side) These companies trade at 2–4× the multiples of vertical SaaS or semiconductor software. PDF’s data platform is the reason. 10. Investment Conclusion PDF Solutions is not a tool company. It is not a software company. It is not a vertical SaaS company. PDF is becoming the data‑infrastructure layer of the semiconductor industry — the only company positioned to unify electrical, equipment, process, yield, and lifecycle data across fabs, nodes, and customers. The market has not priced in: • the compounding nature of PDF’s data • the switching‑cost moat • the platform‑level lock‑in • the strategic dependency created by DFI/eProbe • the cross‑fab standardization trend • the HBM‑driven explosion in electrical defectivity data The correct framing — the one that unlocks the real valuation — is simple: It’s the data, stupid.

$PDFS The opportunity set remains meaningful, but only if discipline keeps pace with ambition. Execution pathways should simplify rather than expand in complexity from here. Any disconnect between guidance and results will be magnified by sentiment. Sustainable upside exists, but only alongside disciplined follow‑through.
