Power Diodes Market Forecast Scenarios

power-diodes-market-size-forecast-scenario-1790811508892
Global power diodes demand grew steadily between 2020 and 2025, expanding at roughly a 7.1 percent historical annual rate as electric-vehicle and renewable-energy investment sustained demand across most tracked global buyer programs, with Japanese and Taiwanese vendors leading much of this expansion worldwide today. This pattern holds across most regions. This pattern holds across most producing regions.
The base case rests on three mechanisms: continued global electric-vehicle expansion across major consuming automotive and charging-infrastructure markets sustaining baseline diode-deployment volume, rising gallium nitride investment expanding the category's addressable efficiency-conscious base considerably, and steady silicon carbide adoption sustaining demand beyond entry-level standard formats across expanding global inverter installations. East Asia's scaled semiconductor fabrication base is positioned to capture a durable share of this incremental demand ahead of competitors still building comparable production depth worldwide. This pattern holds across most regions.
The bull case turns on accelerated gallium nitride adoption pulling growth toward the high teens worldwide as switching-efficiency economics scale faster than expected across major global power-electronics programs. The bear case is persistent capital-expenditure caution among smaller inverter-maker budgets limiting premium adoption to years with favorable infrastructure funding, slowing growth toward the mid single digits worldwide. Across most producing markets.

East Asian Fabrication Capacity Anchors Global Supply

Global power diodes dynamics reflect a genuinely engineering-driven trade, where East Asia's concentrated fabrication base supplies a disproportionate share of global demand given Japan and Taiwan's extensive semiconductor manufacturing scale, and the vendors who lead this category built their advantage through either broad multi-application power-platform coverage or deep silicon carbide engineering specialization that new entrants cannot replicate quickly at comparable cost across most tracked global accounts. Across most tracked producing regions worldwide.
MARKET CONCENTRATION42% CR5held by five vendors across most global buyer procurement channels
AVERAGE UNIT VALUE$0.85 per diode unit shippedwide-bandgap formats command a considerable premium consistently overall
TOP COUNTRY SHAREJapan, 17%reflects deep semiconductor fabrication and packaging production heritage overall
WIDE BANDGAP FORMAT SHARE9% of category revenueremains the fastest growing format tracked in this category
DIRECT OEM CHANNEL SHARE46% of category revenuedirect automotive and inverter-maker procurement agreements anchor category revenue
WAFER INPUT COST SHARE34% of unit COGSspecialty wafer inputs dominate total unit cost consistently
Commercially, the category rewards vendors who can serve both large automotive-scale programs and smaller industrial accounts from a shared fabrication and wide-bandgap-integration architecture, since cross-selling into this broader global customer base lets vendors spread specialty wafer costs further than serving one channel alone. Distribution through direct OEM procurement partnerships and regional distributor relationships remains the primary lever shaping how fast any vendor can scale share. Across most regions.
The next decade will be shaped by gallium nitride diodes continuing to capture efficiency-conscious demand, rising global electric-vehicle investment tied to switching-efficiency and thermal-tolerance targets, and buyers that increasingly reward vendors who can document verified switching-efficiency and thermal-tolerance data at a level legacy standard-only sourcing has historically not needed to prove. This pattern holds across most regions.
"A power diode used to just sit quietly on the board rectifying current and nobody thought much about logging switching-efficiency data remotely, now the same diode increasingly ships with characterization data verifying thermal-tolerance performance in real time, and an inverter maker wants proof of that reliability before signing off on the next platform-qualification cycle."

Market Trends

Wide Bandgap Format Reaches Mid Size Inverter Makers

Documented gallium nitride power diodes, which carry certified switching-efficiency and thermal-tolerance verification data rather than the standard rectifier diodes that historically defined this category for decades, have moved from a flagship-large-automotive-only requirement into mainstream mid-size inverter specification since 2023 as wafer and packaging costs declined enough to reach broader production budgets worldwide. This documented reliability addresses a genuine efficiency-conscious demand that generic unverified claims alone could never satisfy as directly once major power-electronics programs began proliferating quality-traceability initiatives across buyer networks nationwide. This pattern holds consistently across most tracked global producing regions.
Market Impact: Adds 5% more EV-driven demand

Global Electric Vehicle Investment Steadily Broadens Coverage

Worldwide electric-vehicle investment, particularly as global buyers increasingly specify branded, efficiency-verified diodes rather than accepting generic unverified alternatives, is reshaping how vendors fabricate and market diodes to a broader base of discerning mid-tier inverter-maker buyers beyond traditional flagship-large-automotive supply alone, a sophistication shift that has intensified since 2023 as more buyers began requiring documented efficiency specifications directly from every qualified vendor consistently across the world's largest producing regions today.

Market Impact: Extends certification timelines by 5 months

Market Restraints and Challenges

Capital Expenditure Caution Steadily Limits Category Growth

Persistent capital-expenditure caution among smaller inverter-maker budgets remains a genuine, recurring headwind, limiting premium wide-bandgap adoption primarily to the years with favorable infrastructure funding rather than delivering the consistent year-round adoption growth the category historically enjoyed across most global producing regions. The root cause is that many smaller power-electronics firms still view wide-bandgap diodes as discretionary rather than essential spending relative to core production-budget allocations outside flagship large-automotive programs. Vendors are mitigating this through tiered licensing agreements and phased-procurement contracts, though pricing-pressure headwinds still limit category growth across most tracked global accounts.
Market Impact: Cuts switching losses 7 percent

Complex Thermal Certification Slows New Entrants

Demonstrating consistent thermal-tolerance certification across varying voltage-stress and switching-frequency conditions requires genuinely extensive laboratory-testing infrastructure, a persistent friction point distinct from the capital-expenditure headwind the category otherwise faces across most tracked global producing regions. The root cause is that certification thresholds vary considerably by application-configuration complexity, largely outside individual vendor control. Vendors are mitigating this through multi-condition testing programs and reinforced thermal documentation, though full certification still remains a lengthy process for newer entrants across most tracked global producing regions today. This pattern holds consistently across most tracked producing regions.

This pattern holds consistently across most tracked global producing markets and vendor accounts worldwide. Across most tracked producing markets.

Validating Diode Switching Reliability Through Testing

Vendors investing in genuinely extensive voltage-stress and switching-frequency condition trials and third-party validation across their wide-bandgap lines are capturing global OEM trust that unvalidated competitors cannot win as easily, since commercial procurement programs increasingly require demonstrated efficiency documentation before committing to a full-scale long-term supply contract worldwide. One vendor's 2024 efficiency-validation program reportedly cut switching losses by roughly 7 percent relative to standard industry validation processes used previously across comparable global buyer accounts. This pattern holds consistently across most tracked global producing markets and vendor accounts worldwide. Across most producing markets.
Market Impact: Cuts switching losses by roughly 7 percent yearly

Building Dedicated Power Semiconductor Research Programs

Vendors investing in genuinely rigorous switching-efficiency and thermal-tolerance research infrastructure across multiple global OEM tiers are capturing reliability-conscious demand that standard-only competitors cannot win as easily, since commercial procurement programs require demonstrated efficiency consistency before committing to a full switch away from established vendors worldwide. One vendor's 2024 semiconductor research program reportedly expanded its addressable global revenue by roughly 5 percent within a single fiscal year across tracked global accounts, a meaningful gain. This pattern holds consistently across most tracked global producing markets and vendor accounts worldwide. Across most tracked producing markets.
Market Impact: Expands addressable global revenue by roughly 5 percent

Building Dedicated OEM Relationship Support Programs

Vendors building dedicated OEM and distributor relationship and technical integration support programs are capturing trust-driven demand that self-marketed-only competitors cannot win as easily, since commercial procurement teams increasingly seek a vendor's direct technical support before committing to a premium wide-bandgap long-term supply contract worldwide, particularly as budget cycles tighten.

This pattern holds consistently across most tracked global producing markets and vendor accounts worldwide. This pattern holds consistently across most tracked global producing markets and vendor accounts.
Market Impact: Reaches new OEM segments roughly 3 months sooner

Who Controls the Margin Pool

Five vendors hold just over two fifths of global branded revenue, a fragmented market reflecting how Infineon's broad multi-application power-semiconductor platform coverage as an established industry leader and onsemi's deep silicon carbide engineering integration depth have together built advantages that smaller regional vendors are only beginning to meaningfully challenge. The gap between the two leaders' combined coverage and depth and smaller regional competitors remains meaningful in large automotive-scale accounts, though niche vendors continue capturing share in smaller industrial segments worldwide.
Current competitive activity centers on three fronts: switching-reliability validation capturing global OEM trust, power semiconductor research investment capturing reliability-conscious demand across most major producing markets, and dedicated OEM relationship programs capturing trust-driven demand. Regional distribution partnership building is becoming a meaningful differentiator among vendors as regional sophistication accelerates, a differentiation strategy gaining importance industry-wide currently. Across most regions.

Pressure is building from niche regional vendors offering differentiated cost efficiency and local technical support that established global majors cannot always match given their broader but sometimes less regionally responsive commercial focus. Rankings could shift meaningfully if a vendor achieves genuine breakthrough in wafer-fabrication cost efficiency before competitors, capturing the category's fastest-growing tier before it becomes standard practice worldwide. Overall.

Competitive Moat and Risk Dimensions

INFINEON TECHNOLOGIES AG

Moat: Broadest power semiconductor coverage

Infineon's extensive multi-application power-semiconductor platform infrastructure, built specifically as an established industry leader across global automotive and industrial platform coverage over decades of dedicated operation, gives it market-access and reach advantages that smaller regional vendors cannot easily replicate at comparable consistency across most tracked accounts and buyer programs worldwide today. Across most producing markets.
INFINEON TECHNOLOGIES AG

Risk: Narrower silicon carbide engineering depth

Infineon's much narrower dedicated silicon carbide engineering integration specialization relative to onsemi's established decades-long specialization limits its credibility-differentiation among reliability-conscious global OEM buyers, a depth gap that could slow broader specialty-tier account penetration relative to more brand-forward competitors like onsemi over time. This gap is narrowing slowly. This pattern holds across most regions.
ONSEMI CORPORATION

Moat: Deepest silicon carbide engineering depth

onsemi's extensive dedicated silicon carbide engineering integration infrastructure, built specifically for buyer-grade performance over decades of dedicated specialist operation as a category pioneer, gives it category-specific credibility and technical depth that smaller regional vendors cannot easily replicate at comparable scale across most producing markets tracked closely today. Worldwide today.
ONSEMI CORPORATION

Risk: Narrower power semiconductor platform breadth

onsemi's much narrower dedicated coverage-breadth footprint relative to Infineon's established worldwide multi-application infrastructure limits its market-access breadth outside silicon-carbide-heavy categories, a scale difference that could slow broader multi-category account penetration relative to more widely integrated competitors like Infineon over time. This gap is narrowing slowly as onsemi expands. This pattern holds across most regions.

Across most producing markets.
Signal: Indicates research-focused vendors are formalizing engineering programs to defend demand broadly across producing regions. Across most producing markets.

Specialty Wafer Inputs

Specialty silicon and silicon carbide wafer inputs represent roughly thirty-four percent of cost of goods sold for a typical diode vendor, sourced primarily from established fabrication hubs in Japan, Taiwan, and increasingly China. Vendors increasingly favor long-term supply agreements over spot-market contracting to manage this exposure effectively. This pattern holds consistently across most tracked producing regions.
Global silicon and silicon carbide wafer costs fluctuated meaningfully through 2021 and 2022 as broader semiconductor supply-chain disruption and specialized-fabrication capacity constraint affected sourcing simultaneously, a volatility event documented in company annual filings and IEA reporting, before stabilizing through 2023 and 2024 as sourcing markets normalized across most major producing regions. That volatility accelerated global vendor interest in fabrication diversification and vertical integration significantly across the industry, reshaping procurement strategy for years afterward

Larger vendors with diversified sourcing absorbed the 2021 and 2022 cost volatility without major pricing increases, protecting global OEM customer relationships during the disruption, while smaller regional vendors reliant on single-source wafer purchasing more often passed costs through immediately, risking the price-sensitive portion of their customer base at exactly the moment wide-bandgap-driven demand was accelerating fastest across several tracked global regions today. Overall.
power-diodes-market-cost-volatility-analysis-1790811509611

Diversifying Specialty Wafer Sourcing

Vendors are diversifying specialty silicon and silicon carbide wafer sourcing across multiple fabrication regions and geographies, reducing dependence on any single supplier and giving global procurement teams meaningfully more negotiating position during periods of material-supply volatility across the broader semiconductor-manufacturing sector that historically pressured smaller regional vendors hardest during weak sourcing cycles. Worldwide today.

Building Direct Wafer Foundry Relationships

Building long-term, direct relationships with wafer foundry and substrate producing operators reduces dependence on intermediary distribution arrangements entirely, giving vendors meaningfully more control over cost, quality, and delivery timing than smaller competitors relying entirely on intermediary sourcing typically achieve, especially during periods of broader supply disruption across the wider semiconductor-manufacturing industry. Across most producing markets.

Formalizing Multi-Year Material Supply Agreements

Formalizing multi-year supply agreements with key fabrication operators ahead of rising demand reduces exposure to the sourcing volatility that periodically affects this material-dependent category with limited alternative infrastructure, a meaningful advantage as wide-bandgap adoption continues scaling steadily. These agreements give global vendors more predictable planning horizons overall across multiple fiscal years. Across most tracked producing markets.

Portfolio Architecture for Margin Defence

The global category organizes into three commercial tiers. A volume and commodity-adjacent tier competes on price using standard rectifier and basic Schottky formats for mainstream OEM inclusion, a premium and certified tier commands a real price premium tied to fast recovery and silicon carbide formulations with dedicated technical support, and a smaller sustainability and next-generation tier built around gallium nitride power diodes commands the strongest per-unit margin despite the smallest current volume base. Across most tracked producing markets.
Efficiency-validation investment is concentrating premium tier growth among vendors with established automotive-scale and quality-control infrastructure, while the volume tier remains genuinely competitive between global majors and regional vendors fighting for the same price-sensitive standard segment across most producing regions. Volume-tier power diodes still anchor total category unit sales despite carrying the thinnest margins by a meaningful spread across most tracked global.

High-value margin pools concentrate in the sustainability and next-generation tier, where gallium nitride power diodes support the strongest pricing power available today across the global category, and in distributor-advised channels where vendors can command premium pricing without facing the same cost sensitivity present across smaller-vendor distribution segments. Vendors able to defend both tiers simultaneously hold the strongest long-term competitive position worldwide.

Volume / Commodity-Adjacent Tier

Standard rectifier and basic Schottky formats competing primarily on price for mainstream OEM inclusion, distributed broadly to electronics channels worldwide with minimal efficiency documentation attached. This tier still anchors total category unit volume.
Gross Margin: 18-25%

Premium / Certified Tier

Fast recovery and silicon carbide formulations carrying formal technical support and documented efficiency certification, merchandised at a meaningful price premium over standard diodes. This tier is growing steadily among global OEMs seeking documented sourcing diversity.
Gross Margin: 27-34%

Sustainability / Regulatory / Next-Generation Tier

Gallium nitride power diodes aimed at the most engaged, highest-spending precision-focused global automotive programs, commanding the category's strongest per-unit margin despite still-limited volume relative to standard grades currently. Demand here is expanding fastest as more global OEMs prioritize verified switching-efficiency performance.
Gross Margin: 36-44%
power-diodes-market-portfolio-architecture-1790811509802

High-value Sub-segments and Strategic Watch-out

Gallium Nitride Segment

This high-value, high-growth tier is expanding fastest as differentiated efficiency documentation reaches mainstream global OEM credibility, making it the clearest near-term margin opportunity worldwide today. Early movers hold a durable edge as validation capacity fills before entry compresses margins meaningfully across the largest global buyer accounts
Gross Margin: 36-44%

Silicon Carbide Segment

High-value and steadily growing, silicon carbide power diodes command meaningful pricing power tied to genuine high-voltage and thermal-resilience positioning claims, though volume remains constrained relative to standard formats by continued OEM-modernization budgets still scaling steadily worldwide. This segment benefits as wide-bandgap-proliferation demand expands across most producing markets.
Gross Margin: 28-34%

Standard and Schottky Segment

The volume core of the global category, standard rectifier and Schottky power diodes anchor total unit sales across electronics channels and remain the format most buyers encounter first, even as premium formats capture growing category revenue share. This core stays largest by volume for years across most producing.
Gross Margin: 19-25%

Regional Vendor Segment

The strategic watch-out segment, regional vendors are narrowing the price gap with global majors fastest at the category's least differentiated price point, and their continued expansion could compress branded pricing power meaningfully absent further validation differentiation investment worldwide. This bears close monitoring across coming years ahead.
Gross Margin: 9-15%

From Standard to Wide Bandgap

Global power diodes demand behaves more like an annuity relationship once an OEM establishes a qualified vendor and supply contract, since repeat engagement frequency among converted automotive-scale programs runs meaningfully higher than for occasional trial-batch engagements, giving vendors a predictable revenue base than the category's still-uneven wide-bandgap penetration might otherwise suggest across mature global markets tracked today. This pattern holds across most producing regions.
Adoption depth varies meaningfully by end-use vertical: large automotive-scale programs show the deepest technical and efficiency-specification integration and highest repeat engagement rates given their systematic approach to long-term qualification-cycle protocols, industrial-inverter makers adopt more cautiously through phased trial engagements before committing to an ongoing branded-format routine, and independent smaller electronics channels represent a distinct segment tied specifically to individual-project sourcing rather than broad-spectrum commercial positioning alone. Across most tracked producing markets.

Younger power-electronics engineers entering the industry through digitally-influenced precision culture show meaningfully more comfort specifying wide-bandgap and verified-efficiency formats than an older generation of circuit designers who relied primarily on conventional standard purchasing practices passed down across their own engineering experience, a generational shift reshaping how vendors position premium power diodes across their broader commercial outreach programs today and going forward

Where MMA Sees the Real Opportunity

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / SWITCHING RELIABILITY VALIDATION PRIORITY

Build documented evidence before rivals do

Switching-reliability validation remains the clearest lever for capturing global OEM trust, and vendors investing in genuine testing infrastructure now will hold a durable credibility advantage as competitors relying on generic unverified claims struggle to match demonstrated energy-loss economics across most tracked producing markets worldwide. Testing infrastructure takes meaningful time to develop and confirm properly across different voltage-stress and switching-frequency conditions found across global power-electronics programs today. Vendors that delay risk losing this fast-growing category to faster-moving validation-focused competitors already active before it matures into a defensible commercial standard worldwide.
02 / POWER SEMICONDUCTOR STRATEGY

Build reliability capability before rivals do

Dedicated power semiconductor research investment remains the single biggest lever for capturing reliability-conscious demand, and vendors investing in genuine research infrastructure now will hold a durable credibility advantage as competitors relying on standard testing struggle to match validated reliability economics across most tracked global accounts. Research infrastructure takes meaningful time to build and validate properly across different diode configurations and thermal conditions found across global power-electronics programs today. Vendors that delay risk losing this fast-growing global segment to faster-moving research-focused competitors already active worldwide across most producing markets.
03 / OEM RELATIONSHIP STRATEGY

Build technical programs before rivals do

Dedicated OEM and distributor relationship programs remain the clearest lever for capturing trust-driven demand, and vendors investing in genuine technical support infrastructure now will hold a durable credibility advantage as competitors relying on self-marketed claims struggle to match validated advisory economics worldwide. Relationship infrastructure takes meaningful time to build and validate properly across different global OEM networks and regional markets tracked closely today. Vendors that delay risk losing this defensible position to faster-moving relationship-focused competitors already active in the category today across most producing markets.
04 / REGIONAL DISTRIBUTION STRATEGY

Partner with OEMs before competitors do

Regional distribution partnerships provide a structured channel to reach fast-growing sophistication-driven producing markets beyond established Japanese and Taiwanese manufacturing hubs that conventional flagship-only distribution cannot access cost-effectively at meaningful scale worldwide. Vendors formalizing these partnerships now will establish access before competitors fully consolidate that relationship themselves across fast-growing regions worldwide, particularly across South Asia and Pacific and North America. This partnership approach requires genuine investment in local relationship and technical support rather than treating fast-growing markets as an afterthought opportunity, and vendors that wait risk losing this channel entirely.

MARKET MINDS ADVISORY · CLIENT ENGAGEMENT SUMMARY
Power Diodes Producer Strategic Portfolio Review and Transition Roadmap 2026·Investment Scenario on Power Diodes Exposure Evaluation 2025-26
CLIENT PROFILE
The client is a mid-sized Asian automotive-electronics supplier reporting annual component-procurement budget of approximately 8.4 million dollars (client-reported, unverified by MMA) evaluating whether transitioning a meaningful share of its diode sourcing from standard to gallium nitride formats would justify the associated investment given intensifying switching-efficiency requirements. This pattern holds consistently across most tracked producing regions.
STRATEGIC CHALLENGE
Leadership needed to determine which wide-bandgap technology partnership and validation protocol would deliver the best combination of efficiency credibility, thermal reliability, and cost given the firm's existing vendor relationships and appetite for capital investment. Leadership also weighed timing risk carefully, since delaying the transition further risked losing preferred-vendor pricing status across its production pipeline. Across most producing markets.
MMA APPROACH
MMA combined primary survey data with global OEM and vendor interviews to benchmark realistic transition timelines and cost outcomes, modeled wide-bandgap technology partnership options across three commercial scenarios, and produced a phased diode-transition sequence tailored to the firm's existing vendor relationships and available budget, including direct efficiency testing review before finalizing recommendations. Across most regions.
KEY FINDINGS
  1. Efficiency-validated power diodes achieved meaningfully higher retention rates than continued standard sourcing across every tested global OEM segment. Results exceeded initial firm projections meaningfully across the engagement overall.
  2. Validation documentation timelines exceeded firm projections for the most complex multi-condition testing during peak production seasons. Additional field audit cycles were required before full transition.
  3. Simpler single-condition validation protocols achieved meaningfully faster validation timelines, making phased rollout essential to full transition success overall. This sequencing insight shaped the recommended three-phase implementation strategy directly.
  4. Bulk validation procurement across multiple global OEM segments secured meaningfully better unit pricing than pursuing certification individually would have achieved. This pricing advantage strengthened the case for the formal validation partnership.
CLIENT PROFILE
The client is a mid-sized Asian automotive-electronics supplier reporting annual component-procurement budget of approximately 8.4 million dollars (client-reported, unverified by MMA) evaluating whether transitioning a meaningful share of its diode sourcing from standard to gallium nitride formats would justify the associated investment given intensifying switching-efficiency requirements. This pattern holds consistently across most tracked producing regions.
STRATEGIC CHALLENGE
Leadership needed to determine which wide-bandgap technology partnership and validation protocol would deliver the best combination of efficiency credibility, thermal reliability, and cost given the firm's existing vendor relationships and appetite for capital investment. Leadership also weighed timing risk carefully, since delaying the transition further risked losing preferred-vendor pricing status across its production pipeline. Across most producing markets.
MMA APPROACH
MMA combined primary survey data with global OEM and vendor interviews to benchmark realistic transition timelines and cost outcomes, modeled wide-bandgap technology partnership options across three commercial scenarios, and produced a phased diode-transition sequence tailored to the firm's existing vendor relationships and available budget, including direct efficiency testing review before finalizing recommendations. Across most regions.
KEY FINDINGS
  1. Efficiency-validated power diodes achieved meaningfully higher retention rates than continued standard sourcing across every tested global OEM segment. Results exceeded initial firm projections meaningfully across the engagement overall.
  2. Validation documentation timelines exceeded firm projections for the most complex multi-condition testing during peak production seasons. Additional field audit cycles were required before full transition.
  3. Simpler single-condition validation protocols achieved meaningfully faster validation timelines, making phased rollout essential to full transition success overall. This sequencing insight shaped the recommended three-phase implementation strategy directly.
  4. Bulk validation procurement across multiple global OEM segments secured meaningfully better unit pricing than pursuing certification individually would have achieved. This pricing advantage strengthened the case for the formal validation partnership.
RECOMMENDED STRATEGY
Phase 1: Phase 1 (Months 1 to 3): Launch pilot validation on the simplest single-condition segment to validate documentation assumptions and readiness fully. Phase 2: Phase 2 (Months 4 to 9): Expand validation across remaining global OEM segments with technology-partner-supported audits and dedicated documentation support in place. Phase 3: Phase 3 (Months 10 to 14): Formalize long-term branded supply agreements based on full validation performance data collected throughout the engagement.
OUTCOME
Within three quarters of phased validation, the firm reportedly achieved meaningfully fewer switching-related failures while maintaining comparable component costs (client-reported, unverified by MMA), supporting a decision to formalize a long-term branded supply agreement ahead of the original fourteen-month timeline MMA had modeled for the full engagement overall. Across most producing markets.
