Key Takeaways EMCOR raised 2026 guidance as record RPOs and infrastructure demand support long-term growth.Jacobs posted a record backlog, expanded AI and consulting capabilities, and increased expected PA synergies.EME's 35.19% trailing ROE exceeds Jacobs', reflecting stronger shareholder return efficiency. The demand for mission-critical industrial, government, healthcare and data center projects has ramped up across the United States over the past few years and is currently reaching its peak, given the public funding growth and market trends. Firms like EMCOR Group, Inc. (EME - Free Report) and Jacobs Solutions, Inc. (J - Free Report) sit at the juncture and are currently gaining from these market tailwinds.

EMCOR offers mechanical and electrical construction, industrial and energy infrastructure services for a diverse range of businesses, serving commercial, industrial, utility and institutional clients in the United States. Meanwhile, Jacobs offers professional, technical and construction services to industrial, commercial and governmental clients.

Let’s closely compare the fundamentals of the two infrastructure stocks to determine which one is a better investment now.

The Case for EMCOR StockFederal and state investments in water infrastructure, transportation, healthcare modernization, institutional facilities and energy-related projects are creating a healthy pipeline of opportunities for EMCOR. At the same time, AI-driven data center expansion and broader digital transformation continue to fuel commercial construction demand. Owing to these robust trends, EMCOR’s record remaining performance obligations (RPOs) reached $15.62 billion as of March 31, 2026, up 32.9% year over year and nearly 18% sequentially, providing exceptional visibility into future revenue generation. RPOs in the construction segments highlighted contributions of $8.56 billion in U.S. mechanical construction and $5.61 billion in U.S. electrical construction, with additional contributions from building services.

Management emphasized that it continues to see no signs of slowing demand as customers expand data center capacity and adopt advanced liquid cooling technologies. Reflecting this confidence, EME raised its full-year 2026 revenue guidance to $18.5-$19.25 billion from $17.75-$18.5 billion and increased its EPS guidance to $28.25-$29.75 from $27.25-$29.25 expected earlier. Supported by disciplined project selection, execution capabilities and broad market diversification, the company appears well-positioned to capitalize on multi-year infrastructure investment trends.

Meanwhile, strategic acquisitions remain an important pillar of EMCOR's long-term growth strategy, complementing its strong organic expansion. The company's acquisition of Miller Electric has strengthened its electrical construction capabilities, expanded its geographic presence and increased exposure to attractive end markets. Rather than pursuing scale for its own sake, EMCOR prioritizes disciplined capital deployment and integration, preserving its operational culture while creating cross-selling opportunities across its construction and services platforms.

EME ended the first quarter of 2026 with approximately $916 million in cash and about $1.25 billion in working capital, supporting organic investments, strategic acquisitions and operational needs. Management expects full-year 2026 operating cash flow to remain broadly in line with net income, reflecting the underlying strength of the business despite quarterly working-capital fluctuations.

The Case for Jacobs StockJacobs continues to benefit from long-term structural demand across data centers, semiconductors, water infrastructure, transportation and energy & power, reporting more than 100% year-over-year growth in its data center business, supported by accelerating AI investments and strong hyperscaler demand. PA Consulting acquisition is further enhancing growth through advisory, digital transformation and national security opportunities, creating meaningful cross-selling potential. Management has already increased expected annual cost synergies from the acquisition to more than $20 million within 24 months.

These demand drivers helped Jacobs deliver a record backlog of $27 billion, up 22% year over year, with a strong trailing 12-month book-to-bill ratio of 1.4x, providing excellent revenue visibility and supporting confidence in sustained long-term growth. The company is executing a strategy focused on expanding higher-margin consulting, digital and lifecycle solutions while strengthening its leadership in resilient infrastructure markets. Jacobs continues to invest in AI-enabled engineering solutions, including digital twins developed with NVIDIA Omniverse, reinforcing its competitive positioning in rapidly expanding AI infrastructure, advanced manufacturing and mission-critical facilities.

Besides, Jacobs continues to strengthen its global footprint through expanding operations across North America, Europe and the United Kingdom. Recent project wins with Ofwat, Scottish Hydro Electric Transmission and global hyperscale data center customers further demonstrate growing international opportunities. With diversified end markets, strong bookings, improving margins and an upgraded fiscal 2026 outlook, Jacobs appears well-positioned to capture expanding global infrastructure and digital transformation spending, even though execution risks and macroeconomic uncertainties pose a near-term threat.

Notably, Jacobs maintains a balanced capital allocation strategy that simultaneously funds long-term growth while delivering substantial shareholder returns. It repurchased $472 million of shares during the first half of fiscal 2026 and increased its quarterly dividend by 12.5%, reflecting confidence in future cash generation.

Investment Decision: Should Investors Choose EME Stock or J Stock?EMCOR combines record remaining performance obligations, raised 2026 revenue and earnings guidance, disciplined acquisitions and broad exposure across mechanical, electrical, healthcare, institutional and industrial construction, providing exceptional earnings visibility. Its superior execution and industry-leading 35.2% ROE further strengthen the investment case. Although the stock trades at a premium, its recent price momentum, upward earnings estimate revisions and improving fundamentals justify the higher valuation.

Jacobs remains an attractive long-term infrastructure play, supported by record backlog, rapid data center growth, AI-enabled engineering capabilities and expanding consulting opportunities through PA Consulting. However, mixed earnings estimate revisions, greater exposure to consulting execution and slower share price momentum make its near-term outlook comparatively less compelling.

Key Takeaways EMCOR's electrical construction revenues rose 33.1% to a record $1.45B in first-quarter 2026.Network and communications revenues surged nearly 50% on AI infrastructure and data-center demand.EMCOR's remaining performance obligations reached a record $15.62B on strong market bookings. EMCOR Group's (EME - Free Report) electrical construction business continues to build strong momentum, supported by robust demand for mission-critical infrastructure and the company's ability to execute complex projects at scale. In the first quarter of 2026, the segment delivered record revenues of $1.45 billion, up 33.1% year over year, while maintaining an industry-leading operating margin of 12.1%. Although margins eased slightly due to acquisition-related amortization, profitability remained strong, highlighting the resilience of EMCOR's operating model.

The biggest growth driver remains network and communications, where revenues surged nearly 50% as hyperscalers and enterprises accelerated investments in AI infrastructure and data centers. Beyond this, EMCOR benefited from healthy demand across institutional projects, hospitality and entertainment, including stadium construction, as well as higher volumes of short-duration projects and service work. This broad-based demand reduces reliance on any single end market and supports sustainable long-term growth.

Looking ahead, management expects the momentum to continue. Remaining performance obligations climbed to a record $15.62 billion, driven by strong bookings across data centers, healthcare, institutional, water and wastewater and manufacturing markets. The company also continues expanding its geographic footprint while leveraging prefabrication, virtual design, workforce training and disciplined contract management to improve execution on increasingly complex projects.

With AI-driven data center construction showing no signs of slowing and diversified demand across multiple infrastructure markets, EMCOR's electrical construction segment appears well-positioned to remain a key contributor to the company's growth throughout 2026 and beyond.

How Do EMCOR's Peers Compare in Electrical Construction?Two of EMCOR's closest competitors in electrical and mechanical contracting are Quanta Services (PWR - Free Report) and Comfort Systems USA (FIX - Free Report) . Both companies are benefiting from the same secular drivers, including AI data center construction, grid modernization and expanding infrastructure investment.

Quanta continues to strengthen its electrical construction business through large-scale transmission, substation and renewable energy projects, while also increasing its exposure to data centers and communications infrastructure. Quanta has leveraged its engineering expertise and nationwide workforce to secure long-duration projects, giving it strong revenue visibility. As AI-related power demand rises, Quanta is expected to remain a key beneficiary of utility and hyperscaler spending.

Comfort Systems is also expanding its presence in mission-critical facilities through electrical, mechanical and building automation services. Comfort Systems has steadily increased its exposure to data centers, semiconductor manufacturing and advanced industrial facilities, supported by strategic acquisitions. Comfort Systems further benefits from higher-margin service work and prefabrication capabilities that improve execution and profitability.

While both Quanta and Comfort Systems are well-positioned, EMCOR's diversified project portfolio, disciplined contract management and broad geographic reach provide it with a strong competitive position in the rapidly growing electrical construction market.

EMCOR currently sports a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks #1 Rank stocks here.

Many stocks have benefited from the generative artificial intelligence (AI) revolution, not just the "Magnificent Seven" or tech stocks in general. Companies across many other industries have also benefited greatly from the growth bonanza driven by this revolutionary technology.

A prime example of this is EMCOR Group (EME 7.30%). With a $37.3 billion market cap, EMCOR is a fairly large company, but it is hardly a household name. However, this is about to change. Even as shares have surged, the AI data center build-out boom remains in its early stages. This leaves this industrial stock well-positioned to keep winning, and for more investors to take notice.

EMCOR Group at a glance Based in Norwalk, Connecticut, EMCOR Group is a provider of construction, engineering, and property management services. Since its formation in 1994, the company has grown into one of the largest names in the space. EMCOR achieved this scale in large part due to the aggressive acquisition of smaller competitors.

That said, the main driver of growth lately hasn't come from roll-up acquisitions or other financial engineering strategies. Rather, chalk it up to the AI data center boom. Between 2023 and 2025, revenues zoomed from $12.6 billion to nearly $17 billion, thanks to robust demand for electrical, mechanical, and other construction work. During this time frame, earnings more than doubled, from $13.37 to $28.30 per share.

This growth wave has yet to slow down. During Q1 2026, EMCOR reported 19.7% year-over-year revenue growth, with quarterly earnings rising 30%. Alongside strong results, management also issued an upward revision to full-year 2026 guidance, raising its revenue guidance from between $17.8 billion and $18.5 billion to between $18.5 billion and $19.3 billion, with earnings per share (EPS) guidance raised from between $27.25 and $29.25 per share to $28.25 to $29.75 per share.

Better yet, some sell-side analysts anticipate an even stronger 2026 performance. For 2026, the high end of analyst forecasts calls for revenue of $19.2 billion and earnings of over $30 per share.

Why this AI infrastructure stock has more room to run Even as the market has yet to fully catch on, EMCOR's AI growth has already driven the stock higher. Trading at around $175 per share in mid-2023, the stock now trades at around $845 per share. With this big run-up, EMCOR has also climbed toward a premium valuation.

At current prices, the stock trades for around 28.5 times forward earnings. While reasonable compared to other construction stocks, shares may seem at risk of a de-rating due to slowing earnings growth. However, taking a closer look, don't assume this is imminent.

For instance, consider EMCOR's reported earnings growth last quarter, plus the fact that it beat consensus by $0.94 per share last quarter, the latest forecasts appear too conservative. Comps could prove tough in the coming quarters, but as long as growth merely normalizes rather than screeches to a halt, shares will likely sustain a premium valuation and continue to rise in tandem with earnings growth.

AI data center growth could slow, but EMCOR could still maintain elevated growth. Data center construction and electrical work today translates into maintenance and property management work for EMCOR tomorrow. As high growth continues, and the broad market becomes aware of EMCOR's "AI growth" bona fides, shares could reach even loftier price levels. Given this opportunity, it's prime time to make this AI stock a long-term holding and build a position on any major weakness.
