Current report

For the nine months ended September 30, 2025, service revenue was $292.4 million, relatively flat compared to the same period in the prior year. Year-over-year, the demand for laboratory crude-assay services and well completion diagnostic services continued to grow in the international markets. Additionally, reservoir rock and fluid analysis services have been negatively impacted due to the decline in international offshore commercial success rates for exploration and appraisal well projects, as discussed above.

Current report

Sequentially, the slight decrease was due to the lower level of U.S. onshore drilling and completion activity but was substantially offset by higher levels of bulk shipments to international markets.

Current report

G&A expense for the three months ended September 30, 2025, was $10.7 million, which increased $2.0 million, compared to the same period in 2024. The year-over-year increase was primarily due to higher stock compensation expense recorded in 2025. In 2024, a portion of stock compensation expense that was previously recognized was reversed to align with the expectations of vesting levels for certain performance share awards.

Current report

G&A expense for the three months ended September 30, 2025, was comparable to the prior quarter and increased $0.2 million or less than 2%.

Current report

Revenue from the Reservoir Description operating segment of $255.4 million for the nine months ended September 30, 2025 decreased 2% from the same period in the prior year. The decreased revenue in 2025 is primarily due to lower revenue in reservoir rock and fluid analysis in the U.S., as discussed above. The decrease is partially offset by higher revenue in international laboratory crude-assay services and higher laboratory instrument sales in 2025.

Current report

Operating income of $4.4 million for the three months ended September 30, 2025, increased $1.1 million year-over-year, and increased $1.2 million sequentially. Operating margins for the three months ended September 30, 2025, were 9%, compared to operating margins of 7% year-over-year and sequentially. Year-over-year, the increase in operating income and margins was primarily driven by a different mix of revenue with higher well completion diagnostic service revenue that yields a higher margin. Sequentially, the increase in operating income and margins was primarily driven by incremental revenue of $2.4 million in the three months ended September 30, 2025.
Removed paragraphs (6)

Previous report

For the six months ended June 30, 2025, service revenue was $191.3 million, a decrease of 1% compared to the same period in the prior year, primarily driven by the disruptions to the maritime movement and trading of crude oil during the first quarter of 2025, as discussed above.

Previous report

Sequentially, the increase was due to a higher levels of bulk shipments to international markets, as well as higher level of laboratory instrumentation sales.

Previous report

Sequentially, cost of product sales as a percentage of product sales improved due to improved absorption of fixed costs on a higher revenue base, partially offset by the write-down of certain inventory as previously discussed.

Previous report

G&A expense for the three months ended June 30, 2025, decreased $3.2 million compared to the prior quarter primarily due to the acceleration of stock compensation expense for retirement eligible executives of $3.5 million in the first quarter of 2025, partially offset by changes in employee compensations costs in these periods.

Previous report

Revenue from the Reservoir Description operating segment of $167.2 million for the six months ended June 30, 2025 decreased 2% from the same period in the prior year. The decreased revenue in 2025 primarily due to the temporary disruption of the maritime movement and trading of crude oil and derived products which occurred in the first quarter of 2025. The decline in international offshore commercial success rate for exploration and appraisal wells projects, discussed above, has also negatively impacted the level of activity on international projects planned for 2025.

Previous report

Operating income of $3.1 million for the three months ended June 30, 2025, decreased $1.3 million year-over-year, and increased $1.6 million sequentially. Operating margins for the three months ended June 30, 2025, were 7%, compared to operating margins of 10% year-over-year and 4% sequentially. Year-over-year, the decrease in operating income and margins was primarily driven by a total charge of $1.3 million associated with employee severance, facility consolidation and inventory write-downs in 2025, compared to $0.3 million in 2024. Sequentially, the increase in operating income and margins was primarily due to 1) incremental revenue of $1.2 million in the three months ended June 30, 2025, 2) certain employee severance and facility consolidation costs of $0.5 million recorded in the prior quarter, and no such transaction in the current quarter; and 3) a $1.1 million increase the first quarter of 2025, due to the acceleration of stock compensation expense for retirement of eligible executives. These increases partially offset by inventory write-downs of $0.8 million recorded in the second quarter of 2025, no such transaction recorded in the prior quarter.
Reworded paragraphs (39)

Previous wording

According to the latest reports from the U.S. Energy Information Administration, the International Energy Agency and the Organization of the Petroleum Exporting Countries and other oil producing nations (“OPEC+”), global demand for crude oil and natural gas is expected to continue increasing in 2025 and beyond. Beginning in April 2025, the announcement of new tariffs by the U.S. has triggered global trade negotiations and has raised the level of uncertainty for global economies. Additionally, OPEC+ affirmed their decision to proceed with a gradual return of 2.2 million barrels of daily production by removing the voluntary production restrictions established in 2023. The gradual increase in production from OPEC+ began in May 2025 with incremental increases in production expected through September 2026. OPEC also published an updated “compensation plan” which shows committed reductions in production for countries that produced volumes over their committed quotas since January 2024, which if complied with, should partially offset the scheduled increases to production quotas. In each announcement from OPEC+ regarding the production increases, they have also stated they will continue to hold monthly meetings to review market conditions, conformity, and compensation.

Current wording

According to the latest reports from the U.S. Energy Information Administration, the International Energy Agency (“IEA”) and the Organization of the Petroleum Exporting Countries and other oil producing nations (“OPEC+”), global demand for crude oil and natural gas is expected to continue increasing in 2025 and beyond. New tariffs announced by the U.S. during the year have triggered global trade negotiations and have raised the level of uncertainty for global economies. Additionally, OPEC+ affirmed their decision to proceed with a gradual return of 2.2 million barrels of daily production by removing the voluntary production restrictions established in 2023. The gradual increase in production from OPEC+ began in May 2025 with incremental increases in production expected through September 2026, which could create a surplus in supply and lead to lower commodity prices. OPEC also published an updated “compensation plan” which shows committed reductions in production for countries that produced volumes over their committed quotas since January 2024, which if complied with, should partially offset the scheduled increases to production quotas. In each announcement from OPEC+ regarding the production increases, they have also stated they will continue to hold monthly meetings to review market conditions, conformity, and compensation.

Previous wording

The uncertainty around the impact global trade negotiations may have on global economies combined with OPEC+’s announcement of increased production quotas has also increased the likelihood that global inventory levels of crude oil will rise, thereby contributing to weaker crude oil prices. The Company believes that activity levels associated with smaller-scale, short-cycle crude oil development projects will be more sensitive to a decrease and/or continued volatility of crude-oil prices. As such, we expect changes in crude oil prices will have a greater impact on drilling and completion activity levels in the U.S. onshore market. Outside the U.S., large-scale international oil and gas projects are expected to be more resilient to the near-term volatility of crude-oil prices, and the Company anticipates current client projects to continue as planned and additional projects scheduled this year to also be executed as planned.

Recently, revised IEA field data showed that a steeper natural decline rate may represent a dominant long-term supply risk, where the agency projected a sustained upstream investment of approximately $540 to $570 billion per year is required to prevent disruptive declines and to avoid price volatility.

Previous wording

The ongoing geopolitical conflicts between Russia and Ukraine and in the Middle East, along with associated and expanded sanctions in the United States, the European Union, the United Kingdom and other countries continue to cause disruptions to traditional maritime supply chains and the trading of crude oil and derived products, such as diesel fuel. These disruptions to the trading and maritime transportation of crude oil, also impact the demand for the Company's associated laboratory assay services. Although demand for the Company’s laboratory assay analysis services increased in the second quarter compared to the first quarter of 2025, these geopolitical conflicts and associated sanctions continue to create a higher level of uncertainty. We have no way to predict the progress or outcome of these events, and any resulting government responses are fluid and beyond our control.

Previous wording

We continue to focus on large-scale core analyses and reservoir fluids characterization studies in most oil-producing regions across the globe, which include both newly developed fields and brownfield extensions in many offshore developments in both the U.S. and internationally. In the U.S., we are involved in projects with many of the onshore unconventional basins and offshore projects in the Gulf of Mexico. Outside the U.S., we continue to work on many small and large-scale projects analyzing reservoir rock and fluid samples in every major producing region of the world. Notable larger projects are in locations such as offshore South America, Australia, West Africa and the Middle East. Analysis and measurement services also occur in every major producing region of the world. Additionally, some of our major clients have increased their investment in projects to capture and sequester carbon dioxide in recent years that has expanded the Company’s activities on these projects beginning in 2024 and into 2025.

Operating Results for the Three Months Ended June 30, 2025 compared to the Three Months Ended June 30, 2024 and March 31, 2025 and for the Six Months Ended June 30, 2025 compared to the Six Months Ended June 30, 2024

Current wording

Operating Results for the Three Months Ended September 30, 2025 compared to the Three Months Ended September 30, 2024 and June 30, 2025 and for the Nine Months Ended September 30, 2025 compared to the Nine Months Ended September 30, 2024

Previous wording

Service revenue is primarily tied to activities associated with the exploration, appraisal, development and production of oil, gas and derived products outside the U.S. For the three months ended June 30, 2025, service revenue was $96.2 million, flat year-over-year and an increase of 1% sequentially. Year-over-year, revenues remained relatively flat due to an increase in international markets offset by a reduction in the U.S. market. Despite disruptions from the ongoing geopolitical conflicts and expanded sanctions in January 2025, we had some recovery in demand for our laboratory assay services during the second quarter of 2025 and continued growth in well completion diagnostic services in certain international markets when compared to the same period in 2024. Service revenue in 2025 has been negatively impacted by certain projects that were planned and scheduled but were canceled, as the wells drilled by our clients were determined to be uneconomical or unsuccessful.

Current wording

Service revenue is primarily tied to activities associated with the exploration, appraisal, development and production of oil, gas and derived products outside the U.S. For the three months ended September 30, 2025, service revenue was $101.1 million, an increase of 2% year-over-year and an increase of 5% sequentially. Year-over-year, revenues increased primarily due to the increase in international markets partially offset by lower activity level in the U.S. market. Despite disruptions from the ongoing geopolitical conflicts and expanded sanctions throughout the first nine months of 2025, we continue to see recovery in demand for our laboratory crude-assay services during the third quarter of 2025 and continued growth in well completion diagnostic services in certain international markets when compared to the same period in 2024. Service revenue in 2025 has been negatively impacted by certain projects that were planned and scheduled but were canceled, as the wells drilled by our clients were determined to be uneconomical or unsuccessful.

Previous wording

Sequentially, the increase in service revenue was primarily due to a recovery in demand for laboratory assay services in international markets partially offset by a decrease in the U.S. market. As discussed above, the expanded sanctions announced in January 2025 had caused a temporary disruption in the trading and maritime transportation of crude oil and derived products, and demand for the associated laboratory assay services declined during the first quarter of 2025. These activities re-stabilized in the second quarter of 2025 and demand for our associated crude assay services also increased during the three months ended June 30, 2025.

Current wording

Sequentially, the increase in service revenue was primarily due to an increase in demand for laboratory crude-assay services in international markets while the U.S. market remained relatively flat. As discussed above, the expanded sanctions imposed throughout the year have caused a temporary disruption in the trading and maritime transportation of crude oil and derived products that slowed the growth of laboratory crude-assay revenue during 2025.

Previous wording

Product sales are primarily tied to supporting the U.S. onshore drilling and completion activities and bulk product sales to international markets. Product sales to international markets are typically sold and shipped in bulk, and revenue can vary from one quarter to another. For the three months ended June 30, 2025, product sales revenue of $33.9 million decreased 1% year-over-year and increased 19% sequentially. The decrease was driven by lower drilling and completion activity onshore in the U.S. for the three months ended June 30, 2025 when compared to the same period in 2024, resulting in a lower level of product sales in the U.S. onshore market.

Current wording

Product sales are primarily tied to U.S. onshore drilling and completion activities and product sales to international markets. Product sales to international markets are typically sold and shipped in bulk, and revenue can vary from one quarter to another. For the three months ended September 30, 2025, product sales revenue of $33.4 million decreased 6% year-over-year and 2% sequentially. The decrease was driven by lower drilling and completion activity onshore in the U.S. for the three months ended September 30, 2025 when compared to the same period in 2024.

Previous wording

For the six months ended June 30, 2025, product sales revenue was $62.4 million and decreased 7% compared to the same period in the prior year, primarily due to decreased sales in the U.S. onshore markets as a result of lower average drilling and completion activity in 2025 compared to 2024, which was partially offset by increased international bulk product sales.

Current wording

For the nine months ended September 30, 2025, product sales revenue was $95.8 million and decreased 7% compared to the same period in the prior year, primarily due to lower average U.S. onshore drilling and completion activity in 2025 compared to 2024, but was partially offset by an increase of laboratory instrument sales to international markets in 2025.

Previous wording

Cost of services was $74.1 million for the three months ended June 30, 2025, a decrease of 1% year-over-year and an increase of 1% sequentially. The year-over-year and sequential changes in cost of services was in line with changes in service revenue. Cost of services expressed as a percentage of service revenue was 77% for the three months ended June 30, 2025, compared to 78% for the same period in the prior year. Cost of services as a percentage of service revenue remained relatively flat sequentially.

Current wording

Cost of services was $74.9 million for the three months ended September 30, 2025, a decrease of 1% year-over-year and an increase of 1% sequentially. The year-over-year decrease in cost of services was primarily due to increased efficiencies and the benefits of lower compensation costs as a result of cost reduction initiatives implemented during the first half of 2025. Sequentially, the slight increase in cost of services is primarily due to an increase in service revenue partially offset by the increased efficiencies and lower compensation cost as discussed above. Cost of services expressed as a percentage of service revenue was 74% for the three months ended September 30, 2025, compared to 77% for the prior quarter and 76% for the same period in the prior year. Cost of services as a percentage of service revenue improved primarily driven by the efficiencies and cost reduction initiatives as discussed above.

Previous wording

For the six months ended June 30, 2025, cost of services was $147.0 million, a decrease of 1% compared to the same period in the prior year. The year-over-year changes in cost of services was in line with changes in service revenue. Cost of services expressed as a percentage of service revenue remained relatively flat compared to the same period in the prior year.

Current wording

For the nine months ended September 30, 2025, cost of services was $221.9 million, a decrease of 1% compared to the same period in the prior year. Cost of services expressed as a percentage of service revenue improved to 76% from 77% when compared to the same period in the prior year. The year-over-year decrease in cost of services while service revenue remained relatively flat was primarily due to increased efficiencies and cost reduction initiatives as discussed above.

Previous wording

Cost of product sales was $29.6 million for the three months ended June 30, 2025, an increase of 5% year-over-year and 12% sequentially. Cost of product sales expressed as a percentage of product sales revenue was 87% for the three months ended June 30, 2025, compared to 82% for the same period in the prior year and compared to 93% in the prior quarter. The year-over-year changes in cost of product sales as a percentage of product sales increased primarily due to higher absorption of fixed costs on a lower revenue base, along with a write-down of certain inventory of approximately $0.8 million in the three months ended June 30, 2025.

Current wording

Cost of product sales was $30.0 million for the three months ended September 30, 2025, a decrease of 4% year-over-year and an increase of 1% sequentially. Cost of product sales expressed as a percentage of product sales revenue was 90% for the three months ended September 30, 2025, compared to 88% for the same period in the prior year and compared to 87% in the prior quarter. The year-over-year changes in cost of product sales as a percentage of product sales increased primarily due to higher absorption of fixed costs on a lower revenue base that is partially associated with increased tariff cost on certain imported materials, along with a write-down of certain inventory of approximately $0.6 million in the three months ended September 30, 2025.

Previous wording

For the six months ended June 30, 2025, cost of product sales was $56.1 million, a decrease of 5% compared to the same period in the prior year. Cost of product sales expressed as a percentage of product sales revenue was 90% for the six months ended June 30, 2025, compared to 87% from the same period in the prior year. The increase in cost of product sales as a percentage of product sales revenue was due to higher absorption of fixed costs on a lower revenue base and the write-down of certain inventory as discussed above.

Current wording

For the nine months ended September 30, 2025, cost of product sales was $86.2 million, a decrease of 4% compared to the same period in the prior year. Cost of product sales expressed as a percentage of product sales revenue was 90% for the nine months ended September 30, 2025, compared to 88% from the same period in the prior year. The increase in cost of product sales as a percentage of product sales revenue was due to higher absorption of fixed costs on a lower revenue base as discussed above, along with a write-down of certain inventory totaled $1.8 million in 2025, with no such write-down in the same period in the prior year.

Previous wording

G&A expense for the three months ended June 30, 2025, was $10.5 million, which increased 2% or $0.2 million, compared to the same period in 2024. The slight year-over-year increase was primarily due to increased consulting and license fees associated with implementation costs of a global human capital management system partially offset by gains on our company owned life insurance policies in 2025 compared to 2024.

Current wording

For the nine months ended September 30, 2025, G&A expense was $34.8 million which increased $4.1 million, compared to the nine months ended September 30, 2024. The year-over-year increase was primarily due to (1) a higher total stock compensation cost of $1.8 million; (2) a lower gain from mark-to-market adjustments on Company-owned life insurance policies of $1.3 million; and (3) increased license fees and implementation costs associated with a new global human capital management system.

Previous wording

Depreciation and amortization expense for the three months ended June 30, 2025, was $3.7 million, a decrease of 3% year-over-year and 1% sequentially. Depreciation and amortization expense for the six months ended June 30, 2025, was $7.4 million, a decrease of 3% year-over-year. The decrease in depreciation and amortization expense compared to the prior year periods and sequentially is primarily due to assets which became fully depreciated.

Current wording

Depreciation and amortization expense for the three months ended September 30, 2025, was $3.6 million, a decrease of 2% year-over-year and sequentially. Depreciation and amortization expense for the nine months ended September 30, 2025, was $11.0 million, a decrease of 3% year-over-year. The decrease in depreciation and amortization expense compared to the prior year periods and sequentially is primarily due to assets that had become fully depreciated.

Previous wording

During the six months ended June 30, 2025 and 2024, as a result of consolidating and exiting certain facilities in the U.S. and other international locations, we recognized a write-down of the associated leasehold improvements, right of use assets and other assets and incurred lease abandonment and other exit costs of $0.7 million and $1.8 million, respectively.

Current wording

Previous wording

On July 4, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act includes significant provisions, including tax cut extensions and modifications to the U.S. and international tax frameworks. We are evaluating the impact of these legislative changes as additional guidance becomes available, and uncertainty remains regarding the timing and interpretation by tax authorities in affected jurisdictions. These legislative changes could have an adverse impact on our future effective tax rate, tax assets and liabilities, including our deferred tax assets and liabilities, and cash payments for tax.

Previous wording

Revenue from the Reservoir Description operating segment of $86.3 million for the three months ended June 30, 2025 relatively flat year-over-year and increased 7% sequentially. The year-over-year revenue growth in the Company’s international projects and crude-assay services was substantially offset by lower revenue in the U.S. market. Sequentially, the increase in revenue was primarily due to higher revenue in laboratory crude-assay services, as the trading and maritime transportation of crude oil and derived products re-stabilized in the second quarter of 2025, after the expanded sanctions were announced in January of 2025. Additionally, revenue associated with manufactured laboratory instrumentation sales increased sequentially. Revenue in 2025 has been negatively impacted by the decrease in the success rate for international offshore exploration and appraisal wells, which reached a 20-year low for the six-month period ending March 31, 2025. The decrease in international offshore commercial success rates has resulted in the cancellation of several reservoir rock and fluid analysis projects that were originally planned for late 2024 and 2025.

Current wording

Revenue from the Reservoir Description operating segment of $88.2 million for the three months ended September 30, 2025 decreased 1% year-over-year and increased 2% sequentially. Revenue in 2025 has been negatively impacted by the decrease in the success rate for international offshore exploration and appraisal wells, which reached a 20-year low for the six-month period ending March 31, 2025. The decrease in international offshore commercial success rates has resulted in the cancellation of several reservoir rock and fluid analysis projects that were originally planned for late 2024 and 2025. The slight decrease in year-over-year revenue was primarily due to lower revenue in reservoir rock and fluid analysis projects in the U.S. but was substantially offset by higher revenue from international projects and crude-assay services. Sequentially, the increase in revenue was primarily due to higher revenue in laboratory crude-assay services.

Previous wording

Operating income of $12.2 million for the three months ended June 30, 2025, increased $0.8 million, year-over-year and $9.9 million sequentially. Operating margins were 14% for the three months ended June 30, 2025, compared to 13% year-over-year, and 3% sequentially. Year-over-year, the increase in operating income and operating margins was primarily attributable to insurance recovery associated with the fire at the Aberdeen, U.K. facility of $2.6 million recorded in the three months ended June 30, 2025, compared to a $1.3 million gain in the same period in prior year.

Current wording

Operating income of $16.6 million for the three months ended September 30, 2025, was relatively flat year-over-year and increased $4.4 million sequentially.

The additional gain on insurance recovery was substantially offset by a different mix of revenue with a higher level of laboratory instrument sales in 2025, which yield a lower margin.

Previous wording

Sequentially, the increase in operating income and operating margins was primarily due to 1) incremental revenue of $5.4 million in the three months ended June 30, 2025; 2) insurance recovery associated with the fire at the Aberdeen, U.K. facility of $2.6 million recorded in the three months ended June 30, 2025, and no such gain in the prior quarter; 3) a $2.4 million increase in the first quarter of 2025, associated with to the acceleration of stock compensation expense for retirement eligible executives; and 4) a total charge of $2.9 million associated with employee severance, facility consolidation and asset write-down recorded in the three months ended March 31, 2025, and no such transactions in the current quarter.

Current wording

Sequentially, the increase in operating income and operating margins was primarily due to 1) incremental revenue of $2.0 million in the three months ended September 30, 2025; and 2) insurance recovery associated with the fire at the Aberdeen, U.K. facility of $5.3 million recorded in the three months ended September 30, 2025, compared to a $2.6 million recorded in the prior quarter.
