NMM Borrow Costs Spike as Earnings Loom

Navios Maritime Partners heads into its November 17 earnings date with a curious split: the borrow market suddenly looks far more active, even as the lending pool remains wide open and short positioning stays modest.

The most striking development this week is in the cost to borrow. Lending costs have surged to roughly 3.5%, a near-15-fold increase from the sub-0.2% level seen through most of October. That said, the spike is volatile rather than sustained. The rate was 5.5% on November 2, fell back to 3.5% on November 3, and was sitting below 0.7% for most of the preceding month. Despite the noise in the rate, availability remains extremely loose. Around 2,774% availability means more than 27 shares are available to borrow for every one already borrowed. That compares to a 52-week tightest reading of roughly 2,092%, itself still very comfortable. Short interest at 2.2% of the free float is low by any standard. It has climbed about 36% from early October levels in share terms, but it has eased slightly over the past week. Borrowing costs and borrow demand are telling different stories: the rate spike looks more like mechanical noise in a thinly borrowed name than the start of a conviction-driven short build. Options traders are similarly relaxed. The put/call ratio at 0.87 is fractionally below its 20-day average of 0.90, sitting 1.4 standard deviations on the call-heavy side. That is not a defensive posture.

The Street view on NMM is modestly constructive, though the most recent analyst data is now around two months old. Jefferies carries a Buy rating with a $100 target, raised from $85 in late August following the Q2 print. At $87.04, the implied upside to that target is roughly 15%. Valuation multiples look genuinely cheap. NMM trades at a PE of about 4.5 and an EV/EBITDA near 4.4, with a price-to-book of 0.57. The earnings yield factor ranks in the 85th percentile of the universe, and the EV/EBIT score ranks in the 81st. EPS surprise has also been strong historically, ranking in the 84th percentile. The forward earnings growth picture is less clear: the 12-month forward year-on-year EPS increase score sits in only the 23rd percentile, suggesting the market does not expect the current earnings pace to accelerate.

Ownership at NMM is tightly held and worth noting. Angeliki Frangou has a Schedule 13D activist filing disclosing a 17.7% stake as last reported in March 2026. The 13D designation signals active intent rather than passive holding. Frangou has also been buying steadily through a 10b5-1 plan, with daily open-market purchases recorded through early August totalling around 9,000 shares. Because the trades are under a pre-arranged plan, they carry less immediate signal about near-term conviction than discretionary purchases would. Combined, the top two non-institutional holders control over a quarter of the outstanding units. Morgan Stanley added around 66,000 shares in the June quarter. The company's ownership structure is concentrated enough that institutional flows in either direction can move the needle quickly. As a disclosure caveat, 13D/G stakes are event-driven filings around the 5% threshold; a holder dropping below 5% may never file again.

The peer group has had a rough week across the board. SHIP fell 7.7%, CMRE dropped 7.5%, and SBLK lost 5.3%. NMM's 1.3% decline over the same period was notably shallower, suggesting it held up better than its dry bulk and container peers despite the sector-wide pressure. The earnings print on August 20 produced a 6.2% gain on the day and a 5.8% gain over the following five days, a constructive historical reaction. The next result is due November 17.

The key question heading into that print is whether the cheap valuation and strong EPS surprise history can offset the tepid forward growth score, with the borrow cost spike a secondary factor worth monitoring as the date approaches.
