Reports First Quarter 2026 Results and Strategic Outlook

Hanford

waste receipts, Nuclear Services project mobilization,

PFAS

technology expansion, and long-term grouting opportunities

support

improved outlook for 2026

ATLANTA

– May 6, 2026 – Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) today announced financial

results and provided a business update for the first quarter ended March 31, 2026.

“As

expected, the first quarter represented a transitional period as we deliberately positioned the Company for what we believe will be a

significant step-up in activity beginning in the second quarter,” commented Mark Duff, President and Chief Executive Officer of

Perma-Fix. “During the quarter, our results were impacted by seasonal softness, which includes lower waste receipts, the timing

of achieving revenue milestones, the deliberate processing and reduction of existing waste inventories to maximize capacity ahead of

anticipated Hanford-related activity, and investments in personnel, training, and facility readiness. While these factors impacted the

performance of the Company for the first quarter, we believe the quarter also marked the final stages of years of preparation to support

a much larger opportunity set across Hanford, Nuclear Services, and PFAS (per- and polyfluoroalkyl substance) destruction.

believe that the transition we have been preparing for is beginning to materialize across our operations. Our Perma-Fix Northwest (PFNW)

facility has begun receiving Hanford ETF (Effluent Treatment Facility) waste, and we continue to work closely with U.S Department (DOE)

contractors on the anticipated start of additional Direct-Feed Low-Activity Waste (DFLAW)-related waste streams. Moreover, DOE leadership

appears to be focused on providing Hanford waste tank retrieval, supplemental to DFLAW, through grouting waste using available commercial

capacity. The PFNW facility provides immediate local capacity we believe would meet the needs of DOE for its objectives over the next

several years. At the same time, our Services Segment has mobilized under the recently awarded Lawrence Livermore National Laboratory

demolition and disposal agreement, which has a reported value of approximately $24 million over a two year period, and our PFAS platform

continues to advance through completed commercial and government-related treatment work, new project wins, and installation of our Gen

2.0 unit, which is designed to expand treatment capacity.

Collectively,

we believe the expanded permit at our Northwest facility, anticipated growth in Hanford-related waste receipts, the long-term grouting

opportunity, renewed momentum in Nuclear Services, and the increasing need for permanent PFAS destruction solutions all reflect years

of investment, technical development, and operational preparation. The expanded permit at our Northwest facility approximately triples

the facility’s permitted liquid mixed waste processing capacity and authorizes the processing of waste annually through macroencapsulation.

In our view, Perma-Fix is now positioned to begin converting this multi-year investment cycle into improved operating performance. Although

the timing of government programs and customer shipments may continue to create quarterly variability, we expect Perma-Fix to deliver

improved performance beginning in the second quarter, through the balance of 2026, and over the longer term as these opportunities continue

to scale.”

Financial

Results

Revenue

was $11.1 million for the first quarter of 2026, compared to $13.9 million for the corresponding period in 2025. Treatment Segment revenue

decreased by approximately $1.3 million to $7.9 million in the first quarter of 2026, from $9.2 million in the same period of 2025. This

decline was primarily due to lower waste volumes and a less favorable average waste pricing mix. Services Segment revenue decreased by

approximately $1.5 million to $3.2 million in the first quarter of 2026, compared to $4.7 million in the first quarter of 2025. The decline

was due in part to reduced field activity, driven by seasonal delays, including winter weather and typical post-holiday slowdowns. Additionally,

Services Segment revenues are project-based, and therefore subject to variability in project scope, duration, and timing of completion.

Overall

gross loss for the first quarter of 2026 was $2.9 million, compared to gross profit of $657,000 for the first quarter of 2025. The decrease

in Treatment Segment gross profit of approximately $3.1 million, along with the decline in gross margin to (36.0)% from 2.7%, was primarily

attributed to lower revenue discussed above. Treatment Segment gross loss and margin were also impacted by an increase in fixed costs

as the Company continues to invest in infrastructure and workforce in anticipation of increased waste volumes, including those under

the DFLAW program at Hanford. Services Segment gross profit decreased by approximately $455,000, and gross margin declined to (1.5)%

from 8.6%, primarily due to lower revenue. Additionally, overall Services Segment gross margin is impacted by the nature of its projects,

which are competitively bid and therefore have varying margin structures.

Operating

loss for the first quarter of 2026 was $7.5 million versus an operating loss of $3.7 million for the corresponding period of 2025. Net

loss for the first quarter of 2026 was approximately $7.5 million, compared to approximately $3.6 million for the first quarter of 2025.

Net loss per share (both basic and diluted) for the first quarter of 2026 was $0.40 per share, versus net loss per share (both basic

and diluted) of $0.19 for the same period in 2025.

Our

Quarterly Report on Form 10-Q for the period ended March 31, 2026, includes disclosure that certain conditions raise substantial doubt

about our ability to continue as a going concern. The Company expects to fund its anticipated cash requirements from cash on hand, expected

cash flows from operations, and borrowing availability under its Revolving Credit facility; however, the Company’s borrowing availability

under its Revolving Credit facility is subject to compliance with applicable financial covenants and other conditions, and its expected

cash flows from operations are subject to timing and uncertainty, including those resulting from ongoing federal spending constraints.

The

Company reported EBITDA of ($7.0) million from continuing operations for the first quarter of 2026, compared to EBITDA of ($3.3) million

from continuing operations for the first quarter of 2025. The Company defines EBITDA as earnings before interest, taxes, depreciation

and amortization. EBITDA is not a measure of performance calculated in accordance with Generally Accepted Accounting Principles in the

United States of America (“GAAP”), and should not be considered in isolation of, or as a substitute for, earnings as an indicator

of operating performance or cash flows from operating activities as a measure of liquidity. The Company believes the presentation of

EBITDA is relevant and useful by enhancing the readers’ ability to understand the Company’s operating performance. The Company’s

management utilizes EBITDA as a mean to measure performance. The Company’s measurement of EBITDA may not be comparable to similar-titled

measures reported by other companies. The table below reconciles EBITDA, a non-GAAP measure, to GAAP numbers for loss from continuing

operations for the three months ended March 31, 2026, and 2025.
