## Exhibit 99.1

**Exhibit 99.1**

**Plug Power Reports Strong Q1 2026 Results with 22% Revenue Growth and 71% Margin Improvement Year over Year** 

SLINGERLANDS, N.Y., May 11, 2026 — Plug Power Inc., a global leader in hydrogen solutions, today reported results for the first quarter of 2026, delivering strong revenue growth, meaningful margin improvement, and continued progress toward profitability.

The Company exceeded its expectations on revenue and delivered its margin and EPS targets for the quarter. This performance reflects disciplined execution across Plug's integrated hydrogen platform, improving unit economics, and continued demand across core markets.

**<u>Q1 2026 Financial Highlights</u>**

&nbsp;&nbsp;&nbsp;&nbsp;· Revenue increased 22% year-over-year to $163.5 million, reflecting growth
across material handling and electrolyzer businesses

&nbsp;&nbsp;&nbsp;&nbsp;· GAAP
gross margin improved to (13%) from (55%) in the prior-year period, representing a 71% improvement in overall margin and a 42 percentage
point improvement in the margin rate year-over-year, driven by sales growth, cost optimization, improved service execution, and fuel
sourcing efficiencies

&nbsp;&nbsp;&nbsp;&nbsp;· Q1
2026 GAAP EPS was ($0.18), inclusive of approximately $140 million primarily associated with non-cash charges related to adjustments
in convertible debt and warrant valuations stemming from changes in the stock market and the Company's stock price escalation;
Q1 2025 GAAP EPS was ($0.21)

&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted
EPS improved to ($0.08) for Q1 2026 from ($0.17) in Q1 2025, excluding the impact of certain non-cash charges; see the reconciliation
below

"Our first quarter results reflect strong commercial execution and continued progress improving the underlying economics of the business and positions us to achieve our EBITDAS positive target in Q4 2026," said Jose Luis Crespo, Chief Executive Officer of Plug. "We exceeded internal expectations on revenue, delivered on our margin and EPS targets, and continue to strengthen our financial position. Our focus remains on execution and growth, driving efficiency, expanding margins, and converting our scale into consistent financial performance."

**Commercial Business Update**

**Material Handling (GenDrive Fuel Cells and GenFuel Systems)**

&nbsp;&nbsp;&nbsp;&nbsp;· Expansion
with existing customer sites, including Amazon and Walmart, and continued new business development

&nbsp;&nbsp;&nbsp;&nbsp;· Record
service performance, with GenDrive per-unit quarterly service costs down over 30% year-over-year, contributing to margin improvement

&nbsp;&nbsp;&nbsp;&nbsp;· Ongoing
demand supported by productivity gains, reliability improvements, and reduced grid dependence

**Electrolyzer Solutions (GenEco)**

&nbsp;&nbsp;&nbsp;&nbsp;· More
than 320 MW of electrolyzer capacity deployed globally

&nbsp;&nbsp;&nbsp;&nbsp;· Over
$8 billion project pipeline across industrial and energy applications

&nbsp;&nbsp;&nbsp;&nbsp;· Execution
on key projects:

○ 100 MW system with Galp Energia (Portugal)

○ 25 MW system with Iberdrola and BP (Spain)

&nbsp;&nbsp;&nbsp;&nbsp;· New
and advancing opportunities:

○ 275 MW award of Front-End Engineering Design with Hy2gen (Québec, Canada)

○ Continued progress with Allied Green Ammonia, including advancement with the Uzbekistan government on a binding tax incentive agreement and the memorandum of understanding (MOU) with Uzbekistan Airports for SAF and e-SAF initiatives, two key steps toward final investment decision (FID)

**Hydrogen Production**

&nbsp;&nbsp;&nbsp;&nbsp;· Hydrogen
fuel sales increased by 22% for Q1 2026 in relation to Q1 2025, driven by customer growth, increasing prices, and reduced customer warrant
charges

&nbsp;&nbsp;&nbsp;&nbsp;· Hydrogen
fuel margin rate improved by 54 percentage points in Q1 2026 versus Q1 2025, stemming from greater leverage on Plug's hydrogen
network with higher volumes, reduced third-party sourcing costs, and efforts to improve network efficiency

&nbsp;&nbsp;&nbsp;&nbsp;· Volume
is one of the key drivers to improve margins on hydrogen fuel sales as it provides even greater leverage on the Company's production
facilities' fixed overhead costs. The Company continues to scale new customer sites and utilization for existing sites.

&nbsp;&nbsp;&nbsp;&nbsp;· Plug's
production facilities in Georgia, Tennessee, and Louisiana provide approximately 40 TPD in total capacity supporting both internal demand
and broader commercial opportunities

**Liquidity and Capital Position**

&nbsp;&nbsp;&nbsp;&nbsp;· Ended
the quarter with over $802 million in total cash, including $223 million in unrestricted cash and approximately $579 million of restricted
cash, which is expected to release ~$50 million per quarter over the next few years

&nbsp;&nbsp;&nbsp;&nbsp;· Anticipated
proceeds of approximately $275 million from hydrogen project asset monetization initiatives, including the previously announced agreement
with Stream Data Centers. At this time, the first transaction for approximately $142 million is expected to close in June.

&nbsp;&nbsp;&nbsp;&nbsp;· Expected
sale of an investment tax credit associated with the St. Gabriel, Louisiana joint venture hydrogen liquefier for $39.2 million, currently
targeted to close by the end of May 2026

&nbsp;&nbsp;&nbsp;&nbsp;· Cash
usage tracking modestly better than the Company's internal plan; sequential improvement in cash usage is expected over the balance
of 2026, with positive EBITDAS targeted in Q4 2026

**Positioned for Long-Term Value Creation**

Plug continues to execute against a clear set of priorities: margin expansion, disciplined capital deployment, and conversion of its project pipeline into profitable growth. The Company remains focused on achieving positive EBITDAS in the fourth quarter of 2026. Operating at the center of the global energy transition, Plug has built a scaled platform spanning hydrogen production, delivery, and end-use applications. Its integrated hydrogen ecosystem remains a key differentiator, which management believes will drive increased revenue visibility, improved asset utilization, and expanding margins as the platform continues to scale.

Management will host a conference call to discuss results and business outlook.

**Explanatory Notes on Use of Non-GAAP Measures**

To supplement the Company's unaudited financial data presented on a generally accepted accounting principles (GAAP) basis, management has used adjusted basic and diluted net loss per share attributable to Plug Power Inc., which are non-GAAP performance-based measures. These non-GAAP measures are among the indicators management uses as a basis for evaluating the Company's financial performance as well as for forecasting future periods. Management establishes performance targets, annual budgets and makes operating decisions based in part upon these metrics. Accordingly, disclosure of these non-GAAP measures provides investors with the same information that management uses to understand the Company's economic performance year over year. In addition, the Company believes these non-GAAP financial measures improve understanding of comparable information from past reports of financial results.

Adjusted basic and diluted net loss per share attributable to Plug Power Inc. should not be considered as an alternative to net income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities as a measure of our liquidity. Adjusted basic and diluted net loss per share attributable to Plug Power Inc. is defined as the basic and diluted attributable to Plug Power Inc. adjusted for, when applicable, impairment, restructuring, legal accruals, write-off of various loans receivable and bad debt, change in fair value of contingent consideration, losses on extinguishment and changes in fair value of convertible debt instruments, finance obligations and warrant liabilities, net, supplier contract modifications, lower of cost or net realizable value inventory adjustments, and provision for excess and obsolete inventory, and product warranty expense, net of the estimated tax effect of these adjustments and any anticipated tax valuation adjustments. The adjustments made to the basic and diluted earnings per share have no income tax effect in light of the Company's full valuation allowance recorded on their deferred tax assets. While management believes that the non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these measures. The measures are not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the exact method of calculation. The Company's non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company's unaudited condensed consolidated financial statements prepared in accordance with GAAP.

In addition, the Company's EBITDAS-positive target for Q4 2026 is a forward-looking non-GAAP financial measure that cannot be reconciled to the most directly comparable GAAP measure, net income (loss), without unreasonable effort. The Company defines EBITDAS as earnings before interest, income tax, depreciation, amortization and share-based expense. This is because the Company is not able to forecast with reasonable accuracy certain items required for such reconciliation, including interest expense associated with financial arrangements, income taxes, and other non-cash or infrequent charges. These items are inherently uncertain, depend on future events outside of management's control, and could materially affect the Company's GAAP results. The Company provides this target to give investors insight into the direction of its operational objectives rather than as a prediction of GAAP earnings.
