Compelling Rationale for Consolidation NMM’s approach for NNA is well-timed, value-enhancing for all equity holders Diversification mitigates segment volatility â–ª Largest US-listed fleet of 140+ vessels – ~ One-third of the fleet in each of the three segments: 55 dry bulk / 43 containerships / 45 tankers – 3 segments / 15 vessel types / 10+ end markets served â–ª Diversification benefits include: – mitigating individual segment volatility – positioning to leverage fundamentals across sectors – balance sheet flexibility and capital allocation options – more predictable entity-level returns to unitholders despite potentially uneven segment performance â–ª Combination eliminates duplicative corporate costs â–ª Balanced portfolio promotes attractive fleet renewal—irrespective of segment conditions â–ª Short to medium-term recovery in oil demand is expected – driving attractive tanker market fundamentals â–ª Acquiring NNA’s fleet (while deleveraging its balance sheet) provides a unique opportunity – En-bloc transaction for a large diversified tanker fleet – Fleet has proven operating performance – Attractive acquisition reflects current tanker market duress – significant upside in asset values and earnings â–ª Prior opportunistic acquisition of Navios Maritime Containers L.P. (“NMCI”) demonstrated benefits of diversification – NMM stock price appreciated 301% since NMCI acquisition announcement – Containership assets values have increased over ~2.6x (1) in 2021 â–ª Combination facilitates a revaluation of the platform â–ª Diversified platform attractive to a broader set of investors seeking exposure to global economy â–ª Low leverage for the combined entity of ~35% LTV (2) provides financial flexibility and collateral buffer â–ª Positive fundamentals in dry and containers and a bullish medium-term tanker outlook â–ª Rationale for combination of NNA and NMM further simplifies the Navios Group structure Strength in Scale Resiliency in Diversification Opportunistic Acquisition of Tanker Company Offers Unitholders Upside Attractive Investment Platform for Broader Group of Investors Source: Navios Management, CapIQ, public company disclosure.
