Ship Mortgage Notes being Redeemed

Conference Call & Webcast: Tuesday, August 31, 2021 at 8:30 am ET

MONACO, August 26, 2021 — Navios Maritime Partners L.P. (“Navios Partners”) (NYSE: NMM), an international owner and operator of dry cargo vessels, and Navios Maritime Acquisition Corp. (“Navios Acquisition”) (NYSE:NNA), an international owner and operator of tanker vessels, announced today a definitive transaction agreement providing for a combination of Navios Partners and Navios Acquisition in a transaction in which shareholders of Navios Acquisition will receive 0.1275 of a common unit of Navios Partners for each outstanding common share of Navios Acquisition. All of Navios Acquisition’s outstanding 8.125% First Priority Ship Mortgage Notes, due on November 15, 2021 (the “Ship Mortgage Notes”), will be redeemed in accordance with their terms with the proceeds of a cash contribution from Navios Partners and newly arranged secured term loan financings (the “Transaction”).

Angeliki Frangou, Chairwoman and Chief Executive Officer, stated, “We are announcing a transformative transaction. The combined entity will be the largest U.S. publicly-listed shipping company in terms of vessel count, with 15 vessel types diversified across three segments, servicing more than 10 end markets. About one-third of our fleet will be in each of the dry bulk, containership and tanker segment. We believe that this combination will result in a stronger, more resilient entity, mitigating sector specific cyclicality. This should enable us to capitalize on opportunities throughout the industry and provide even returns to our stakeholders across cycles.

This combination of two companies with similar core values and beliefs, as it relates to our service offerings, will allow us to continue to deliver the high-quality service that our customers expect. We have a proven model to execute seamless combinations, as evidenced by our prior successful roll-up transactions, and we anticipate a smooth execution for this combination as well.”

Benefits of Combination

The Transaction is expected to:

•

Create the #1 largest U.S. publicly-listed shipping company, with over 140 vessels aggregating approximately 15 million deadweight tons operating in three segments through 15 different vessel types and serving more than 10 end markets.

•

Scale operations with trades across all sizes with about one-third of its vessels operating in each of the three segments.

•

Achieve diversification to mitigate idiosyncratic segment volatility as operational segments are driven by unique fundamentals.

•

Optimize strategy allowing management to take advantage of opportunities within each sector, such as by calibrating charter term based upon segment opportunity.

•

Realize annual cost reductions.

•

Maintain significant financial flexibility with a combined modest leverage ratio of approximately 35%, based upon the average of publicly available broker reports as of August 20, 2021, and a large collateral value base for refinancing debt maturities.

•

Enhance credit profile by increasing cash retention to support growth and continued deleveraging.

•

Grow equity market capitalization and depth in share trading to offer an attractive fundamental investment opportunity to investors seeking exposure to global economy.

•

Maintain and ultimately grow returns to unitholders of the combined company.

•

Provide Navios Acquisition’s shareholders the opportunity to continue to participate in the combined company and avail themselves of market upside

The current value of the combined company’s vessels is estimated at $4.2 billion based upon the average of publicly available broker reports; the combined company will also have an enterprise value of approximately $2.25 billion. With a $1.6 billion pipeline of contracted revenue coupled with about 47,634 available days in 2022, the combined fleet is well-positioned to take advantage of the healthy dry cargo markets as well as any future upturn in the tanker market.

Merger / Merger Consideration

Pursuant to the definitive transaction agreement, Navios Acquisition will merge with a subsidiary of Navios Partners and become a wholly owned subsidiary of Navios Partners. In the merger, Navios Acquisition’s shareholders will receive 0.1275 of a common unit of Navios Partners for each common share of Navios Acquisition. Based on Navios Partners’ August 24, 2021 closing price, the merger consideration reflects a per share value of $3.40, representing premiums to Navios Acquisition shareholders of 65% based on the August 24, 2021 closing price and 17.6% based on the most recent 60-day volume weighted average price of Navios Acquisition’s common shares.

The exchange of shares of Navios Acquisition for common units of Navios Partners in the merger is expected to be a tax-free exchange for shareholders of Navios Acquisition for U.S. federal income tax purposes.

The combined company will be led by the existing board of directors of Navios Partners, comprised of seven directors, a majority of whom are independent.

Redemption and Discharge of Navios Acquisition Ship Mortgage Notes

Pursuant to the definitive transaction agreement, Navios Acquisition has called for redemption all of its outstanding Ship Mortgage Notes (with a redemption date of September 25, 2021) and has discharged its obligations under the Indenture relating to the Ship Mortgage Notes by remitting to the Indenture trustee the aggregate redemption price payable to the holders of the Ship Mortgage Notes.

Navios Acquisition funded the redemption price using a combination of proceeds from the sale pursuant to the definitive transaction agreement of approximately 44.1 million newly issued Navios Acquisition common shares to Navios Partners in exchange for a cash contribution of $150.0 million (the “NNA Equity Issuance”) and borrowings under Navios Acquisition’s newly arranged secured term loan financings. In connection with the new financings, Navios Shipmanagement Holdings Corporation (“NSM”) released all of the collateral securing its loan to Navios Acquisition (the “NSM Loan”) and surrendered its option to exchange all or a portion of the NSM Loan for equity of Navios Acquisition’s material subsidiary, Navios Maritime Midstream Partners L.P. The released collateral was included in the collateral securing Navios Acquisition’s newly arranged secured term loan financings. In addition, NSM canceled $30.0 million of the approximately $98.1 million outstanding balance of the NSM Loan in exchange for 8.8 million newly

issued common shares of Navios Acquisition. The Navios Acquisition common shares issued to NSM will be exchanged in the merger for common units of Navios Partners on the same terms applicable to the other Navios Acquisition shareholders. Any Navios Acquisition common shares owned by Navios Partners (including the shares issued pursuant to the NNA Equity Issuance) will be canceled in connection with closing of the merger for no consideration.

Working Capital Facility

In connection with the Transaction, Navios Partners provided Navios Acquisition with a $45.0 million interim working capital facility.

Approvals

The Transaction was unanimously approved by both the special committee of the Board of Directors of Navios Acquisition (“Special Committee”), consisting of independent directors, and Navios Acquisition’s full board of directors. The Transaction was also unanimously approved by the Conflicts Committee of Navios Partners as well as its full board of directors.

Merger Closing

The closing of the merger is subject to customary closing conditions, including effectiveness of a registration statement on Form F-4 related to the issuance of common units of Navios Partners to the shareholders of Navios Acquisition and the approval of the merger by holders of a majority of the outstanding Navios Acquisition common shares at a special meeting of Navios Acquisition shareholders to be held after the registration statement is declared effective. As a result of the NNA Equity Issuance, Navios Partners owns approximately 62.4% of the outstanding common shares of Navios Acquisition. Pursuant to the definitive transaction documentation, Navios Partners has agreed to vote all of its Navios Acquisition common shares in favor of the merger, which will be sufficient to approve the merger.

The merger is expected to close in the fourth quarter of 2021.
