AST SpaceMobile enters the final day of September with its lending market at a near-complete standstill, short interest approaching a 30-day high, and analysts split across a wide range of targets, a setup that captures the stock's broader tension between commercial promise and bearish conviction.
The most striking development this week is the near-total disappearance of available shares to borrow. Availability has collapsed to just 0.81% of short interest, meaning fewer than one share remains accessible for every hundred already lent out. That is the tightest the market has been in a month, down from 3.8% just the prior session and well below the recent range of 4 to 14% seen across September. Cost to borrow has climbed to 1.50%, up 11% on the week and 29% over the past month, though in absolute terms it remains a modest rate. The combination of near-zero availability and rising borrow cost reflects mounting demand to maintain short positions in a stock where the lending pool has all but emptied. The ORTEX short score confirms the pressure: it has risen steadily from 73.3 to 74.8 over the past two weeks, placing ASTS at the 2nd percentile for short score rank across the universe, meaning almost no stock carries a higher short burden.
Short interest itself has grown meaningfully over September. At 24.2% of free float, the position has expanded by nearly 20% over the past month, rising from roughly 57 million to 67 million shares short. The FINRA fortnightly print to September 15 put short shares at 65.3 million, with days-to-cover at 6.9. The weekly change is a near-flat 0.3%, suggesting the pace of new short building has steadied even as the borrow market tightens around existing positions. Options traders, by contrast, are not adding to the defensive tilt. The put/call ratio of 0.49 is barely above its 20-day average of 0.48, with a z-score of just 0.49, well within normal range. The 52-week high on PCR is 0.67, so there is room to move and it has not. Options positioning reads as neutral, not alarmed.
The analyst community is broadly constructive but fragmented on price. Berenberg initiated with a Buy and a $92 target in early September. Piper Sandler and Cantor Fitzgerald both hold Overweight ratings, with targets at $98 and $90 respectively. UBS stays Neutral at $78, trimming from $80 after the August 11 earnings print. The consensus mean target of $78.48 implies roughly 32% upside from the current $59.40 close, though the range of views is wide. Bears point to device compatibility constraints, the cost of spectrum and legal exposure, and the risk of commoditisation against Starlink. Bulls lean on the satellite ramp, government contract revenue, and the argument that direct-to-device connectivity is still in its first commercial innings. The EPS surprise factor score of 92 is the one quantitative flattery: the company has beaten estimates at a rate that ranks near the top of the coverage universe. The stock's price-to-book is 12.1x, and the EV/EBITDA multiple is economically meaningless for a pre-scale operator of this type.
The ownership register carries its own story. Four Schedule 13D filers are on record, making this one of the more activist-heavy cap tables in the sector. Abel Avellan, the CEO and founder, holds 20.8% as of his last filing in June. Vodafone Ventures trimmed from 6.0% to 5.0%, and Rakuten Mobile reduced from 7.2% to 5.3%, both still on the 13D register. AT&T filed a 13D in February at 2.7%. These are strategic partners, not financial activists, but their presence on the 13D register signals intent beyond passive investment. It also means any stake movements around the 5% threshold carry regulatory disclosure obligations, so the register can shift quietly between filings. On the insider side, the 90-day net is mildly negative: the COO sold 12,000 shares at $58.89 on September 16 in a discretionary sale, while the CTO sold 40,000 shares under a pre-arranged 10b5-1 plan. Director Adriana Cisneros made three open-market purchases in late August totalling just over 10,000 shares, a modest but discretionary counterpoint. The net 90-day value of roughly negative $2.4 million is not alarming at this scale, but the absence of executive buying at current prices is worth noting.
Wikipedia retail attention has eased, running nearly two standard deviations below its own 90-day average as of end-August, a signal that broader public interest has cooled since earlier in the year, even as short positioning has intensified. The next earnings event is scheduled for November 10, six weeks out. With availability at its tightest in recent memory and short interest still near its highest level of the past month, the path to that print is the most immediate thing to watch.
