A 159-Year-Old Boilermaker Just Became an AI Power Story — and Babcock & Wilcox Jumped 36%

Revenue up 130%, backlog up 533%, and a swing from a $58 million loss to a profit — $BW jumped about 36% pre-market after the market finally priced in what the company has quietly been building: gas-fired power plants for AI data centers.

For most of the last decade, Babcock & Wilcox Enterprises was a story about survival. A boilermaker with a famous name, a difficult balance sheet, and a share price that spent much of 2025 trading near a dollar. Then the second-quarter numbers landed after the close on August 10, and $BW printed around $12.09 in pre-market trading the following morning, up roughly 36% from its $8.88 close. Seeking Alpha and Investing.com both covered a quarter that beat on every line that mattered, and the company’s own release is filed with the SEC.

This profile walks through what B&W actually reported, the single project that is transforming its income statement, how a 19th-century boiler company ended up at the center of the AI infrastructure trade, and the specific reasons to keep both hands on the wheel after a move this size.

What actually happened

Babcock & Wilcox reported second-quarter 2026 results after the bell on August 10, and the scale of the beat was unusual. Revenue came in at $319.7 million against a consensus estimate closer to $197 million — not a narrow clear, but a number the Street was not modeling. That figure is 130% above the $138.9 million the company posted in the same quarter of 2025.

Below the revenue line, the swing was just as sharp. B&W reported net income of $14.3 million, versus a net loss of $58.5 million a year earlier. Earnings came to $0.07 per share against a loss of $0.63 in the prior-year quarter. Adjusted EBITDA rose 57% to $21.8 million.

Then management did the two things that turn a good quarter into a re-rating. It raised the upper end of its full-year 2026 adjusted EBITDA target to a range of $80.0 million to $105.0 million, citing stronger first-half results and visibility into second-half demand. And the board authorized a $50 million share repurchase program — a notable signal from a company that spent recent years focused on paying debt down rather than buying stock back.

The numbers that moved it

The number that reframes everything else is backlog. A 533% increase to $2.6 billion is not an operational improvement — it is a different company. For context, B&W’s entire trailing revenue base was a fraction of that figure. Backlog of that size means the work is already contracted; the question shifts from “can they win business” to “can they execute it.”

Twelve months of tape

The chart is essential context that the one-day headline hides. This is not a stock breaking out from a quiet base. BW traded as low as $1.17 and as high as $22.03 within the past year, and it closed at $8.88 the day before this print — roughly 60% below its high. The 36% pop is a violent move inside an already violent chart. Anyone framing this as a steady industrial re-rating is not looking at the same price history.

Inside the business: three segments and one very large project

Babcock & Wilcox operates through three reporting segments, and understanding them explains why this company could pivot into the AI power trade at all.

B&W Thermal is the historic core: steam generation equipment, aftermarket parts, construction, maintenance and field services for power generation, oil and gas, and industrial customers. This is the parts-and-service annuity that kept the company alive, and it is also the segment that owns the engineering competence now being redeployed.

B&W Environmental supplies emissions control and environmental technology for utility, waste-to-energy, biomass, carbon black and industrial steam applications — the scrubbers, filters and control systems that let thermal plants meet regulatory limits.

B&W Renewable covers technologies for sustainable power and heat, including waste-to-energy, oxygen-fired biomass-to-energy, and black liquor systems for the pulp and paper industry. The company also develops a hydrogen production platform under the BrightLoop name.

The transformation, though, runs through a single contract. B&W received full notice to proceed on a $2.4 billion design-build agreement with Base Electron, an independent power producer backed by Applied Digital, to deliver 1.2 gigawatts of new generation capacity built around four 300-megawatt natural gas-fired boilers and steam turbine generator systems. That power is intended to feed Applied Digital’s AI factory campuses. In the second quarter alone, the Base Electron project contributed $100.7 million of revenue — roughly 31% of the total.

The day after earnings, B&W added another piece: an agreement with Siemens Energy to commence work on 20 steam turbine generator sets totaling one gigawatt of generating capacity for its FastPower program, aimed at data center projects. Taken together, the message is that the Base Electron contract is meant to be a template rather than a one-off.

Why the market rewarded it

Three forces stacked up in the same print. First, the revenue beat was enormous in percentage terms — when a company delivers 60% more revenue than the Street modeled, analyst models have to be rebuilt rather than tweaked, and that process tends to move a stock hard.

Second, profitability arrived. B&W has been a company where the bull case required believing in a future that had not yet shown up in net income. A $14.3 million profit against a $58.5 million loss converts the thesis from projection to evidence, even if a single quarter is a small sample.

Third, and most important, the balance sheet stopped being the story. Total debt stood at $276.8 million as of June 30, 2026, down from $349.7 million at the end of 2025, against a cash, cash equivalents and restricted cash balance of $382.8 million. The company also moved to repurchase the remaining $61.8 million of its December 2026 bonds in August. For years the bear case on B&W was a near-term maturity wall; that wall is materially smaller, and cash now exceeds total debt. The $50 million buyback authorization is management saying the same thing in a different language.

The case for caution

Start with concentration. Roughly 31% of second-quarter revenue came from one project for one customer. That is what makes the growth rate so spectacular, and it is precisely what makes it fragile. Large engineering, procurement and construction projects carry schedule risk, cost-overrun risk and counterparty risk, and a single delay at Base Electron would land directly on the reported numbers with nothing to cushion it.

Then there is the arithmetic of the guidance. Adjusted EBITDA was $21.8 million in the second quarter. The full-year target is $80 million to $105 million. Reaching even the low end requires a substantial second-half acceleration, and reaching the top end requires considerably more than that. Management raised the range because it says it has visibility into that ramp — but it is a ramp, not a run-rate, and the market will hold the company to it.

Third, note what kind of profit this is. Earnings of $0.07 per share on a roughly $1.3 billion market capitalization is a thin foundation. Investors buying here are paying for the backlog converting into future margin, not for current earnings power.

Finally, the chart itself is a risk. A stock that has traveled from $1.17 to $22.03 and back to $8.88 inside twelve months attracts momentum capital that leaves as quickly as it arrives. And this is a pre-market quote, which is thin by nature — a 36% indication before the opening bell frequently narrows once real volume arrives.

What to watch next

The first tell is whether BW holds the gap. A 36% pre-market move that gives most of itself back in the opening hours is a very different signal from one that consolidates and builds. Beyond the tape, three things matter. Watch backlog conversion — the rate at which that $2.6 billion turns into recognized revenue is the entire thesis. Watch bookings for a second data-center-scale contract, because the FastPower and Siemens Energy agreements are only meaningful if they produce another Base Electron. And watch the second-half EBITDA ramp against the $80 million to $105 million target; the third-quarter report is the first real checkpoint on guidance management chose to raise.

The bottom line

Babcock & Wilcox delivered a genuinely exceptional quarter: revenue up 130%, a swing to profitability, bookings up 38%, backlog up more than fivefold, a raised full-year target, a repaired balance sheet and a buyback authorization, all in one release. The market’s 36% response was not irrational.

What it was, though, was a response to a company in the middle of a transformation rather than at the end of one. The AI power buildout gave a 159-year-old boilermaker a demand curve it could not have manufactured on its own, and B&W has real engineering assets to meet it. But the revenue is concentrated in one project, the guidance requires a second-half ramp that has not happened yet, and the share price has already demonstrated it can fall as fast as it rises. This is a story worth following closely. It is not a story that has finished being told.
