Department of War Clears Eight AI Vendors onto Classified Networks

  • The Department of War announced agreements with eight frontier AI companies — Amazon Web Services, Google, Microsoft, NVIDIA, OpenAI, Oracle, Reflection, and SpaceX — to deploy their models on its Impact Level 6 and Impact Level 7 classified networks, the two highest tiers of the Department's cloud-security architecture.
  • The significance was less the names than the pace: eight vendors cleared into the most sensitive environments in a single coordinated action under the Acquisition Transformation Strategy signed by Secretary Hegseth in November 2025. Notably absent was Anthropic, whose Claude had been the only large language model on classified networks at scale via Palantir's Maven toolkit.
Energy Markets

Oil Slides ~20% as Iran Ceasefire Talks Advance

  • Oil prices dropped roughly 20% from their 2026 highs as the U.S. and Iran were reported to have mostly agreed on a 60-day memorandum of understanding to extend their ceasefire, pending sign-off from President Trump.
  • Shipping through the Strait of Hormuz, representing about 20% of global energy supply before the conflict, remained well below pre-war levels as Iran continued sporadic strikes, including ballistic missiles aimed at Kuwait.
Trade Policy

Trump-Xi Beijing Summit Yields Trade Commitments, Few Firm Details

  • Following the Beijing summit held on May 14–15, the White House reported that China committed to purchasing a minimum of $17B in U.S. agricultural goods annually through 2028, with an initial order of 200 Boeing aircraft also included.
  • Washington and Beijing provided differing accounts of outcomes, with few concrete agreements reached on trade, technology, or the situation in Iran.
Defense Spending

Shangri-La Defense Summit Centers on Allied Defense Spend

  • At the May 29–31 IISS Shangri-La Summit in Singapore, Secretary of War Pete Hegseth urged allies to allocate at least 3.5% of their GDP for defense spending. Japan, the Philippines, and the Netherlands indicated plans to increase defense budgets; South Korea has already reached that level.
  • China sent a low-level delegation with no defense minister present, amid ongoing tensions over Taiwan and the South China Sea.
Market Commentary

The Department of War announced agreements with eight frontier AI companies — Amazon Web Services, Google, Microsoft, NVIDIA, OpenAI, Oracle, Reflection, and SpaceX — to deploy their models on its Impact Level 6 and Impact Level 7 classified networks, the two highest tiers of the Department's cloud-security architecture. Eight separate vendors were cleared into the most sensitive environments in a single coordinated action under the Acquisition Transformation Strategy, the reform framework signed by Secretary Hegseth in November 2025. Notably absent was Anthropic, whose Claude had been the only large language model on classified networks at scale via Palantir's Maven toolkit.

The Congressional Budget Office released a new estimate projecting that the "Golden Dome for America" missile-defense shield could cost roughly $1.2T over 20 years, well above the administration's current projection of about $18B. Space Force Gen. Michael Guetlein set a target for completion around 2035, with space-based interceptors expected to account for about 60% of the cost. The system is being built largely through a $151B contract vehicle known as SHIELD (Scalable Homeland Innovative Enterprise Layered Defense), under which approximately 2,100 contractors have been named. To date, only about $40B has been allocated, including a roughly $17.1B request in the FY2027 budget.

Ed-tech giant Instructure faced a data-theft and extortion attack on its Canvas learning management system, threatening to leak data from more than 275 million students, teachers, and staff. The outage took Canvas offline during final exams, leaving thousands of schools without access to course materials, grades, and due dates. Instructure said it received digital confirmation of data destruction prior to the May 12 pay-or-leak deadline set by the attackers.

Microsoft introduced MDASH, an AI-driven vulnerability scanner that coordinates over 100 task-specific agents to detect, debate, and confirm exploitable flaws automatically. The system uncovered 16 previously unknown weaknesses in Windows networking and authentication code, including four critical remote-code execution flaws. In a controlled test, it caught all 21 deliberately seeded bugs without a false alarm and ranked first on the public CyberGym benchmark of 1,507 real-world vulnerabilities with an 88.45% score.

On May 18, the EPA proposed two rules that reshape the PFAS regulatory landscape for U.S. drinking water systems. The first would rescind enforceable limits for four chemicals: GenX, PFHxS, PFNA, and the Hazard Index mixtures of these three PFAS plus PFBS. The second would extend the compliance deadlines for the PFOA and PFOS Maximum Contaminant Levels for two additional years, until 2031. Both rules are open for public comment, with a public hearing scheduled for July 7, and the EPA has indicated its intention to finalize the rules before year-end.

American Water and Essential Utilities received merger approval from both the Public Utilities Commission of Ohio and the Commonwealth of Kentucky, moving their proposed merger closer to its anticipated Q1 2027 close. On May 21, American Water also completed regulatory approvals for its $315M acquisition of Nexus Water Group systems in eight states, which ultimately closed on June 1, adding approximately 47,000 customer connections across Maryland, Virginia, New Jersey, and additional states.

Commercial transits through the Strait of Hormuz dropped to their lowest levels since the start of the U.S.-Israel offensive against Iran, with traffic declining steadily from early April through the end of May as the industry remained caught in the crossfire.

Container freight rates continued their upward climb in May, with the Drewry World Container Index rising 6% to $2,712 per 40-foot container through the first three weeks of the month.

The Georgia Ports Authority opened its new $134M Gainesville Inland Port in early May, providing a direct rail link between the Port of Savannah and northeast Georgia. The 104-acre intermodal facility, equipped with seven cranes, is expected to remove approximately 26,000 truck trips from Atlanta-area roads in its first year of operation, a significant infrastructure addition as U.S. ports work to build long-term capacity amid mounting trade disruptions.

Goodwill Impairment Testing Under ASC 350: What PE-Backed Companies Need to Know

Goodwill impairment testing under ASC 350 is an annual obligation with real financial consequences, and rising discount rates have made a poorly documented analysis more costly than ever. In this article, The McLean Group’s Valuation Advisory team examines how the quantitative test works, what triggers interim testing outside the annual cycle, and what a defensible file actually contains. For PE-backed companies approaching an exit, the difference between a well-supported charge and a reactive one can meaningfully affect both timeline and price. […]

Labor Retention and Quality of Earnings: Understanding People-Driven Margin Risk

Workforce stability is one of the most overlooked drivers of earnings quality and in people-driven businesses, it can make or break a transaction.Workforce stability is one of the most overlooked drivers of earnings quality and in people-driven businesses, it can make or break a transaction. In this article, The McLean Group’s Financial Consulting team examines how labor retention risk surfaces during a Quality of Earnings analysis, why below-market compensation and key-person dependencies can distort reported EBITDA, and what buyers and sellers should evaluate before reaching the diligence table. From government contracting to IT services and professional services, the people behind the numbers matter just as much as the numbers themselves, and understanding that dynamic is increasingly essential to assessing the true sustainability of earnings in any middle market transaction.[…]
