Investment Research Report: Cohort plc (CHRT.L) – Strategic Positioning in a Heightened Threat Environment

Date: December 5, 2025 Subject: Cohort plc (CHRT.L) Exchange: London Stock Exchange (AIM) Sector: Aerospace & Defense Report Type: Initiation of Coverage / Deep Dive Investment Analysis

1. Executive Summary

1.1 Strategic Inflection Point

Cohort plc stands at a defining moment in its corporate history as of late 2025. Transitioning from a loose confederation of agile, independent small-to-medium enterprises (SMEs) into a cohesive, mid-tier defense contractor of significant scale, the Group is navigating a period of profound geopolitical instability that has fundamentally reset the demand environment for its products. The investment case for Cohort is anchored in a "super-cycle" of defense spending, catalyzed by the most volatile security architecture since the Cold War and specifically accelerated by the UK Government’s 2025 Strategic Defence Review (SDR). This review, with its emphasis on "warfighting readiness" and "technological innovation at a wartime pace," aligns precisely with Cohort’s portfolio of mission-critical sensors, effectors, and communications systems.

While the broader aerospace and defense sector has seen valuation expansion, Cohort’s share price has experienced a notable dislocation, correcting from a 52-week high of £17.96 to current levels around £10.72. This retracement appears to be a reaction to short-term working capital dynamics—specifically a temporary spike in net debt driven by strategic inventory builds and facility investments—rather than a deterioration of fundamentals. In fact, the underlying business drivers are arguably stronger than at any point in the Group’s history, characterized by record order visibility and a transformative acquisition strategy.

1.2 The Bull Thesis: Visibility, Margins, and Geography

The bullish investment thesis rests on three structural pillars that differentiate Cohort from its peers:

1. Unprecedented Revenue Visibility As of September 2025, the Group’s order book exceeds £590 million, providing revenue cover of nearly 90% for the full financial year 2026 consensus forecasts. This is not merely a short-term backlog; it represents a structural shift in the quality of earnings. The £135 million contract awarded to the SEA subsidiary for the Ancilia maritime countermeasures system anchors this visibility, extending delivery schedules into the mid-2030s. In an industry often plagued by "lumpy" contract awards, Cohort has secured a baseload of work that significantly de-risks its medium-term financial profile.

2. Structural Margin Expansion The acquisition of EM Solutions (EMS), completed in January 2025, serves as a powerful catalyst for margin expansion. Historically, Cohort has operated with net margins in the 10-11% range. EMS, with its heritage of high-value satellite communications for the Royal Australian Navy, operates with Earnings Before Interest and Tax (EBIT) margins of approximately 26%. The integration of this high-margin revenue stream provides a mathematical tailwind to the Group’s blended margins, offering a clear and credible pathway to management’s stated target of "mid-teens" profitability.

3. Geopolitical Alignment (AUKUS & NATO) The portfolio is meticulously aligned with the priorities of the AUKUS alliance (Australia, UK, US) and NATO’s expanded posture. The acquisition of EMS not only improves margins but also establishes Australia as a second "home market," directly exposing the Group to the heightened security spending in the Indo-Pacific. Simultaneously, the EID subsidiary in Portugal has secured a €33 million (£27.8 million) NATO contract, cementing the Group’s role in European interoperability.

1.3 Financial Synopsis

The financial year ended April 30, 2025 (FY2025), established new performance benchmarks. Revenue surged 33% to £270.0 million, and adjusted operating profit climbed 30% to £27.5 million. Despite this growth, the market remains fixated on the H1 FY2026 net debt guidance of roughly £30 million. This analysis posits that the debt spike is a transient feature of the Group’s growth phase—driven by the unwinding of customer advances and the completion of the ELAC SONAR facility in Kiel—and that the projected return to a net funds position of £10 million to £15 million by year-end FY2026 will serve as a key valuation catalyst.

1.4 Investment Recommendation

Outlook: Bullish (Long-Term) / Accumulate (Short-Term) The discrepancy between the company’s fundamental trajectory—characterized by double-digit earnings growth and expanding margins—and its corrected share price presents an asymmetric risk/reward opportunity. The market is pricing Cohort as a cyclical industrial facing headwinds, whereas the data suggests it is a growth compounder benefiting from secular tailwinds. For investors willing to look through the H1 FY2026 working capital noise, Cohort offers exposure to high-grade defense technology at a valuation that discounts its strategic transformation.

2. Business Drivers

2.1 Macro-Strategic Context: The "Warfighting Readiness" Paradigm

To understand Cohort’s business drivers, one must first analyze the radical shift in the macro-strategic environment. The era of the "peace dividend" has unequivocally ended. In its place, Western governments are pivoting toward a posture of "warfighting readiness."

The UK Strategic Defence Review (SDR) 2025 Published in June 2025, the SDR is the most significant overhaul of UK defense policy in decades. The review, accepted in full by the government, outlines a vision for a "tech-enabled Defence power" by 2035. Crucially for Cohort, the SDR moves away from a singular focus on "exquisite platforms" (few, expensive ships/planes) toward the systems that make those platforms effective—sensors, data links, and electronic warfare (EW) capabilities.

The SDR’s three core premises map directly to Cohort’s operational strengths:

1. The Integrated Force Model: The review mandates a move away from siloed operations toward a fully integrated force where data flows seamlessly between domains (land, sea, air, cyber). Cohort’s subsidiaries, particularly EID (tactical communications) and MASS (digital data management), are architects of this connectivity. The ability to integrate NATO-standard communications into diverse platforms is no longer a "nice-to-have" but a prerequisite for procurement.

2. Technological Innovation at "Wartime Pace": The SDR explicitly criticizes legacy procurement timelines and calls for rapid innovation. Cohort’s structure—a federation of autonomous, agile SMEs—is purpose-built for this requirement. Unlike the monolithic Prime contractors, which can be slow to pivot, subsidiaries like Chess Dynamics and MCL can prototype, test, and field solutions (such as counter-drone systems) in months rather than years.

3. The Digital Targeting Web: The SDR allocates a specific £1 billion budget for a "Digital Targeting Web" to integrate battlefield decision-making using AI and cloud technologies. MASS, with its Thurbon electronic warfare database and digital services, is positioned as a critical enabler of this data-centric warfare.

The AUKUS Alliance and the Indo-Pacific Tilt The geopolitical center of gravity is shifting to the Indo-Pacific, driven by the strategic competition between the US and China. The AUKUS alliance represents a generational commitment to sharing advanced defense technology. Cohort’s acquisition of EM Solutions is a masterstroke of timing in this context. It transforms Cohort from a UK-centric entity into a bi-hemispheric player with indigenous industrial capability in Australia, a requirement for winning AUKUS "Pillar 2" contracts (advanced capabilities like quantum, cyber, and EW).

2.2 Operational Analysis: Sensors and Effectors (S&E) Division

The Sensors and Effectors division, comprising Chess Dynamics, ELAC SONAR, and SEA, has historically been the Group’s engine for product innovation. In FY2025, this division generated £145.1 million in revenue, a 21% increase year-on-year.

SEA (Systems Engineering & Assessment) SEA is the current star performer, driven by the transformative £135 million contract for the Ancilia maritime countermeasures system awarded by the Royal Navy in March 2024.

• The Ancilia Significance: Ancilia is a trainable decoy launcher system designed to protect surface ships from modern threats like hypersonic and ballistic missiles. This contract is pivotal for two reasons. First, it provides a long-term revenue baseload, securing employment for 150 skilled staff in North Devon and dampening the volatility of project revenue. Second, the Royal Navy’s endorsement serves as a "gold standard" reference, unlocking an estimated £250 million export market.

• Strategic Pruning: In May 2025, SEA divested its transport business. While this creates a short-term revenue "headwind" due to the loss of non-core turnover, it is a positive strategic development. It focuses management entirely on high-margin, high-complexity defense work, purifying the division’s identity as a naval defense specialist.

Chess Dynamics Chess specializes in precision surveillance and fire control systems. Its Hawkeye and Vision4ce product lines are at the forefront of the counter-unmanned aerial systems (C-UAS) market.

• The Drone Threat: As evidenced by the conflict in Ukraine, drones have become a ubiquitous threat. Chess’s systems use AI-enabled video processing to detect, track, and disrupt small, fast-moving targets that traditional radar might miss. This capability is in high demand for both land-based air defense and naval protection.

• Operational Friction: Despite strong demand, Chess experienced "delays and one-off project costs" in FY2025, which contributed to a compression in the division’s margins to 8.7%. These issues appear to be related to supply chain constraints and the complexities of scaling production for rapid delivery orders. Resolving these operational bottlenecks is a key driver for margin recovery in FY2026.

ELAC SONAR Acquired in 2020, ELAC provides advanced sonar systems for submarines and surface combatants.

• The Kiel Facility Transition: ELAC is currently concluding a major capital expenditure program (£20 million total) to move to a new facility in Kiel, Germany. This move has been a drag on free cash flow and has introduced logistical friction. However, the completion of this facility in H1 FY2026 removes a significant operational overhang and expands capacity to service the long-term sonar supply contract for Italian submarines.

• Market Position: ELAC provides Cohort with a foothold in the German defense market, which is undergoing its own "Zeitenwende" (turning point) in defense spending.

2.3 Operational Analysis: Communications and Intelligence (C&I) Division

The Communications and Intelligence division, comprising EID, MASS, MCL, and the newly integrated EM Solutions, has emerged as the growth and margin leader. In FY2025, revenue surged 50% to £124.9 million, with adjusted operating profit nearly doubling to £21.1 million.

EM Solutions (EMS) EMS is the most critical driver of the Group’s future financial profile. Based in Brisbane, Australia, EMS designs and manufactures high-end satellite communication terminals (Cobra and King Cobra) that allow naval vessels to communicate securely while moving in rough seas.

• Financial Impact: EMS is a high-margin business. In its financial year ended December 2023, it generated AUD 43.1 million (£22.5 million) in revenue with an EBIT of AUD 11.5 million (£6.0 million), implying a margin of ~26.7%. This is more than double the legacy Cohort margin.

• Strategic Fit: EMS brings an order book of AUD 175.4 million (£91.4 million), including a massive AUD 150 million contract to upgrade the Royal Australian Navy’s satellite communications. This long-term visibility parallels the Ancilia contract at SEA, reinforcing the Group’s revenue stability.

MCL (Marlborough Communications Ltd) MCL serves as a prime systems integrator for the UK MoD, specializing in sourcing and integrating advanced electronic and surveillance technology.

• The FY2025 Spike: MCL delivered a "record performance" in FY2025, driven by urgent requirements for hearing protection and drone technologies. Management has transparently guided that FY2026 activity will reduce from this peak as these specific urgent operational requirements (UORs) are fulfilled. This normalization is a natural cycle for a UOR-focused business and should not be misinterpreted as a structural decline.

EID (Empresa de Investigação e Desenvolvimento de Electrónica) Based in Portugal, EID specializes in tactical and naval communications.

• Turnaround Story: After suffering from supply chain component shortages that hampered deliveries in previous years, EID returned to profit in FY2025. The award of a €33 million NATO contract for the Tactical Deployable Communication and Information System (TDCIS) is a massive vote of confidence. It ensures EID’s production lines will be busy through 2026/27 and validates its technology at the highest level of the alliance.

MASS MASS focuses on electronic warfare operational support (EWOS), cyber defense, and digital services.

• The "Thurbon" Advantage: MASS’s proprietary Thurbon data management system is a critical tool for managing the complex data required for electronic warfare. As the SDR pushes for a "Digital Targeting Web," MASS is uniquely positioned to manage the underlying data architectures.

• Recruitment Challenge: The primary constraint on MASS’s growth is the availability of staff with high-level security clearances. The "war for talent" in the cyber and EW domain is fierce, and MASS’s ability to recruit and retain cleared experts is the rate-limiting step for its expansion.

3. Financial Performance (2024-2025)

3.1 Profit and Loss Analysis

The transition from FY2024 to FY2025 demonstrates a step-change in the scale of the Group’s operations.

Revenue Total revenue for FY2025 reached £270.0 million, a robust increase of 33% over the £202.5 million reported in FY2024.

• Driver Analysis: The Communications and Intelligence (C&I) division was the primary growth engine, expanding by 50% to £124.9 million. This was fueled by the exceptional volume at MCL and the initial contribution from acquisitions (EMS and ITS). The Sensors and Effectors (S&E) division grew by 21% to £145.1 million, driven by the ramp-up of SEA’s major contracts and ELAC’s delivery schedules.

Adjusted Operating Profit Adjusted operating profit followed the revenue trajectory, rising 30% to £27.5 million (FY2024: £21.1 million).

• Margin Dynamics: The Group’s overall adjusted operating margin remained relatively flat at 10.2% (FY2024: 10.4%). This aggregate figure masks a significant divergence at the divisional level.

  • C&I Margin Expansion: Margins improved to 16.9% (from 15.4%), reflecting the high-margin contribution from the nascent EMS integration and EID’s return to profitability.

  • S&E Margin Compression: Margins contracted to 8.7% (from 10.7%). This compression was attributed to a "weaker mix" at SEA (likely lower margin pass-through work or early-stage manufacturing costs on Ancilia) and the aforementioned one-off costs at Chess.

Earnings Per Share (EPS) Adjusted EPS increased by 27% to £0.5444 (FY2024: £0.4289). Statutory basic EPS rose 19% to £0.4507. The strong conversion of operating profit to earnings underscores the Group’s efficient tax structuring (benefiting from R&D tax credits) and controlled financing costs.

3.2 Balance Sheet and Cash Flow

The balance sheet dynamics in FY2025 and entering FY2026 are complex and require nuanced interpretation to avoid mispricing the equity.

Net Funds / Debt Position

• Closing Position FY2025: The Group ended the year with net funds of £5.3 million, a significant reduction from £23.1 million in FY2024.

• H1 FY2026 Guidance: Management has guided for a net debt position of approximately £30.0 million at the half-year mark (October 2025).

• FY2026 Year-End Guidance: A projected return to net funds of £10.0 million to £15.0 million by April 2026.

Why the Volatility?

1. Unwinding Customer Advances: Defense contracts often involve large upfront payments (advances). In FY2025, Cohort held significant advances. As work is performed (revenue recognized), these cash balances are consumed, creating a perceived cash outflow.

2. Strategic Inventory: To mitigate supply chain risks and ensure rapid delivery for urgent orders (like those at MCL), the Group has invested heavily in working capital (inventory), locking up cash.

3. Capex Spike: The culmination of the ELAC SONAR facility investment involves significant cash outlays in H1 FY2026.

4. Acquisition Flows: The cash consideration for EMS and associated transaction costs impact the net position.

Return on Capital Employed (ROCE) Despite the capital intensity of the facility move and acquisition, Cohort maintained a Return on Equity (ROE) of 14.4% in FY2025, consistent with its 5-year average. This indicates that management is deploying retained earnings efficiently. The EMS acquisition, with its 26% margin profile, is expected to be accretive to ROCE once the initial integration costs are absorbed.

3.3 Dividend Policy

Cohort is a "Dividend Aristocrat" of the AIM market.

• FY2025 Total Dividend: Increased by 10% to £0.1630 per share.

• Track Record: The dividend has been increased every year since the Group’s IPO in 2006.

• Sustainability: With adjusted EPS of £0.5444, the dividend is covered 3.3x. This high coverage ratio provides ample headroom for continued progressive growth, even during periods of higher investment or net debt.

4. Risk Assessment

Investing in Cohort entails specific sector and operational risks that must be weighed against the growth potential.

4.1 Operational Risks

• Fixed-Price Contract Execution: A significant portion of the order book (e.g., Ancilia, Italian submarines) is likely on a fixed-price basis. In an inflationary environment, cost overruns on materials or labor can erode margins. The margin compression in S&E in FY2025 is a tangible manifestation of this risk.

• Supply Chain Fragility: The delays at Chess and the past issues at EID highlight the vulnerability of the defense supply chain. Sourcing specialized components (semiconductors, high-grade steel) remains a bottleneck. A disruption in the supply of key sub-components could delay revenue recognition and impact cash flow timing.

4.2 Human Capital Risks

• Security Clearance Bottlenecks: Growth at MASS and the cyber-focused units is strictly limited by the ability to recruit staff with "Developed Vetting" (DV) or "Secret" clearances. The pool of such individuals is finite and highly contested by Primes and tech giants. Inability to staff projects could lead to contract penalties or lost opportunities.

4.3 Market and Geopolitical Risks

• Customer Concentration: The UK Ministry of Defence (MoD) accounts for approximately 50% of Group revenue. While the current relationship is strong, any political shift in defense priorities—for instance, a redirection of funds from naval programs to healthcare—would materially impact Cohort. However, the diversification provided by EMS (Australian DoD) and EID (Portuguese MoD) mitigates this risk better than at any previous time.

• Export Licensing: Exporting sensitive electronic warfare technology (like Ancilia) requires strict government approval. Geopolitical shifts could lead to tighter export controls, potentially delaying or cancelling the £250 million export pipeline for SEA’s products.

4.4 Financial Risks

• Currency Fluctuations: The Group now has significant exposure to the Euro (via ELAC/EID) and the Australian Dollar (via EMS). While costs are largely naturally hedged (incurred in the same currency), translation of profits into GBP for reporting can lead to volatility in reported earnings.

• Interest Rate Exposure: With the move to a net debt position in H1 FY2026, the Group is momentarily exposed to interest rate costs. While leverage is low, high rates increase the cost of carry for the debt facility used to fund the EMS acquisition.

5. 5-Year Scenario Analysis (FY2026 – FY2030)

This scenario analysis projects the Group’s financial trajectory based on varying assumptions regarding market conditions and execution.

5.1 Base Case Scenario (Probability: 50%)

Narrative: The UK defense budget meets the 2.5% GDP target by 2028. The SDR recommendations are implemented steadily. EMS integration proceeds as planned, maintaining ~25% margins. SEA successfully delivers the Ancilia contract without major technical issues. Organic growth stabilizes at 5-7% annually.

• Revenue 2030: £420.0 million.

• Net Margin: Expands to 12.5% (driven by EMS mix and S&E recovery).

• Adjusted EPS: £0.85.

• Valuation Implication: Applying a standard defense multiple of 18x, the share price targets £15.30.

5.2 High (Bull) Case Scenario (Probability: 20%)

Narrative: The geopolitical situation deteriorates further, leading to emergency procurement cycles. The "Warfighting Readiness" doctrine triggers rapid, off-the-shelf purchases of Chess’s counter-drone systems and MCL’s surveillance tech. SEA secures two major export customers for Ancilia (e.g., Canada, Japan). EMS leverages AUKUS Pillar 2 to win substantial cyber/EW work. Margins hit management’s "mid-teens" aspirational target.

• Revenue 2030: £550.0 million.

• Net Margin: 15.0%.

• Adjusted EPS: £1.20.

• Valuation Implication: A scarcity premium re-rating to 22x P/E, targeting £26.40.

5.3 Low (Bear) Case Scenario (Probability: 30%)

Narrative: UK fiscal pressures force a "review of the review," delaying major programs. The SDR implementation is sluggish. EMS suffers from integration issues (culture clash, distance), and margins revert to the Group mean. ELAC’s facility move causes extended delivery delays and penalties. S&E margins remain suppressed at ~8-9% due to inflation.

• Revenue 2030: £320.0 million (Stagnation).

• Net Margin: 9.0%.

• Adjusted EPS: £0.58.

• Valuation Implication: De-rating to a cyclical multiple of 12x, resulting in a share price of £6.96.

6. Qualitative Scorecard (1-10 Scale)

The following scorecard evaluates the qualitative aspects of the business that are not captured in the financial statements.

7. Short-Term Technical Outlook

Timeframe: December 2025 – April 2026

• Price Context: The stock is trading at £10.72, a significant retracement from the 52-week high of £17.96. This correction (approx. 40%) places the stock in "bear territory" relative to its recent peak, likely driven by profit-taking and the headline noise regarding net debt.

• Indicator Divergence:

  • Moving Averages: The stock is trading below its 50-day and 200-day moving averages, a classic bearish signal.

  • Oscillators: However, oscillators present a contrasting picture. The Relative Strength Index (RSI 14) is at 63.08 (Buy zone), and the Stochastic (9,6) is at 61.57 (Buy zone). The Williams %R is at -14.08 (Overbought), suggesting strong recent momentum.

  • Interpretation: The divergence between the "Sell" signal from moving averages (lagging indicators) and the "Buy" signal from oscillators (momentum indicators) suggests that the selling pressure is exhausting itself and a reversal may be imminent.

• Support Zones: Key psychological and technical support lies in the £10.00 – £10.50 region. If this level holds, it forms a "double bottom" base for the next leg up.

• Catalyst: The Interim Results announcement on December 10, 2025, is the pivotal event. A confirmation of the H2 weighted recovery and reassurance on the net debt trajectory could trigger a sharp "relief rally," closing the gap toward £12.00.

Verdict: The technical setup favors accumulation. The downside risk appears limited by the strong fundamental support at £10.00, while the upside potential on a positive news cycle is substantial.

8. Conclusion

Cohort plc represents a compelling study in market dislocation. The company has successfully executed a long-term strategy to evolve from a collection of small businesses into an integrated, strategic supplier to the UK and its allies. It possesses the "holy grail" of defense contracting: a massive, long-duration order book (£590m+) and a structural catalyst for margin expansion (EM Solutions).

The market’s current valuation, reflecting a steep discount from 2025 highs, appears to be an overreaction to the temporary mechanics of working capital cycles and capital expenditure. Investors focusing on the H1 FY2026 net debt figure are missing the forest for the trees. The "forest" is a business with nearly 90% revenue visibility, exposure to the highest-growth segments of the defense budget (EW, C-UAS, Comms), and a clear path to significantly higher profitability.

Final Investment Verdict: Cohort plc is a Strong Buy for patient capital. The confluence of the UK Strategic Defence Review’s "warfighting" mandate and the company’s specific capabilities in mission systems creates a multi-year tailwind that is not currently priced into the stock. As the Group transitions past the investment peak of FY2026 and begins to print the improved margins from EMS, a re-rating toward £15.00+ is fundamentally justified.
