ADTRAN Heads Into August Earnings With Bears Dug In and Options Turning Defensive

ADTRAN Holdings enters its August 4 earnings print carrying 15.2% of its free float short — a level that has barely budged all month, and that sits against a stock that has lost a fifth of its value in the past thirty days.

The short interest angle is the dominant story here, and it tells a tale of conviction rather than momentum. Shorts have held firm near 12.1 million shares for weeks, with only a marginal week-on-week drift of -0.07%. The stock closed Tuesday at $12.14, up nearly 5% on the day after Monday's slide, but the weekly picture is still down 3.7%. The ORTEX short score is running at 68.9, close to the top of its recent range and ranking in the 4th percentile of the broader universe on short score — meaning the name is more heavily shorted than roughly 96% of its peers. That is a difficult backdrop to rally through. Days-to-cover from the most recent FINRA settlement sits at 5.4 days, meaning any sharp upward move would take nearly a week of average volume to fully unwind.

The lending market, though, tells a more nuanced story. Borrowing costs have eased sharply — down 17% on the week to just 0.40%, a level that makes new shorts cheap to establish and existing ones inexpensive to hold. Availability has tightened modestly from 252% a week ago to 148% today, but with more than 33 million shares still available to borrow against roughly 12 million already short, the lending pool is nowhere near stressed. That looseness matters: it removes the mechanical squeeze pressure that sometimes forces shorts to cover, leaving positioning cautious but not cornered. The put/call ratio has climbed to 0.93, well above its 20-day average of 0.50 and sitting near the 52-week high of 1.06. That is options traders leaning defensive at a rate more than one standard deviation above the norm — a posture that aligns with the short sellers rather than contradicting them.

The Street is cautiously bullish in its coverage, but the consensus feels dated. Rosenblatt raised its target to $20 and Needham held at $18 after the last quarterly print in early May, while Evercore ISI initiated in April with an Outperform and an $18 target. All three targets sit well above the current $12.14. The gap reflects what the bull case holds: ADTRAN is positioned to absorb a significant slice of the ~$100 billion in US federal broadband subsidies and similar European programmes, its Network Solutions segment has shown sequential progress, and the Adva acquisition adds revenue diversification. Bears push back that customer concentration in optical networking is a real risk, that memory costs remain a headwind, and that the last two quarterly reactions were deeply negative — the stock fell 14% and 17% on successive earnings days, and the five-day moves were worse, reaching -18% and -15% respectively. The EPS surprise factor score of just 10 out of 100 confirms the pattern: this company has consistently missed, not beaten. The one bright spot is the EV/EBITDA multiple of 7.4x, which is undemanding, and the forward earnings momentum scores are modestly positive at 56-66 on a 30-to-90-day view.

Institutional ownership is broadly stable. BlackRock reported a modest addition in June, bringing its stake to 9.7% of shares. State Street added over 600,000 shares to reach 2.9%. Morgan Stanley and JPMorgan both reported meaningful new positions in the April filing window. EGORA Holding trimmed by 1.65 million shares — the one notable reduction among top holders. Insider activity has been net selling through this period: the CTO cleared more than $2.2 million of stock in early May at prices around $14.75-$15.06, and a director sold in March. The net 90-day insider figure appears positive on paper at roughly $2.6 million, but that reflects an award to the CTO; the open-market transactions were one-directional sells.

With earnings due August 4 and the prior two prints delivering double-digit single-day declines, the setup heading into the release is worth watching closely — specifically whether shorts choose to add into any pre-announcement strength, or whether a further softening in availability begins to narrow the exit window for the bears.
