ATS Corporation: Low Short Interest, Loose Borrow, Tight Valuation

ATS Corporation enters November with a quietly defensive setup: short sellers have been rebuilding positions through October while the borrow market remains completely uncongested, leaving the stock's near-term story driven more by valuation and institutional ownership than by any meaningful short-side pressure.

The lending picture is relaxed to an unusual degree. Availability has widened to nearly 1,944% of current short interest, meaning lenders are sitting on roughly 30.8 million shares available to borrow against a short position of only around 1.7 million shares. That is loose by any standard, and the 52-week minimum availability reading was 617%, so even at its tightest this year, borrow supply has been abundant. Cost to borrow is running at 0.76%, up about 11% on the week but still negligible in absolute terms. With short interest at just 1.74% of the free float, the ORTEX short score has drifted lower to 33.3 from 34.1 a week ago, a direction that reflects easing rather than escalating short-side conviction. The month-on-month increase in shares short of roughly 37% bears watching, but the absolute level remains low enough that it does not constitute a meaningful overhang.

The Street picture is mixed, though the most relevant data point is also the stalest. The mean analyst price target sits at CAD 37.30, implying around 41% upside to the current price of CAD 26.50. That gap is large enough to matter, but the consensus data is flagged as stale, with the most recent changes dating to late September, so it reflects positioning from more than a month ago and should be treated with caution. On valuation, the stock trades at a trailing P/E of 14.1 and EV/EBITDA of 9.0, both of which have drifted lower over the past 30 days. The P/E has compressed by roughly 0.44 turns in a month, suggesting modest multiple pressure. Factor scores are broadly middling: earnings yield ranks in the 66th percentile, 30-day EPS momentum scores 76, but 90-day EPS momentum is in the bottom decile at 10, pointing to a stalling earnings revision cycle over the longer window.

The ownership register is dominated by a small number of institutional holders with large, relatively static positions. Mason Capital Management holds 16.9% of shares, making it comfortably the largest single holder. EdgePoint Investment Group and Royal Bank of Canada each hold roughly 6.6% to 6.9%, and Beutel Goodman increased its stake materially in the period to August, adding over 1.4 million shares to reach 6.4%. On the Schedule 13D/G register, there are no activist positions: all filers are passive holders, and no 13D has been filed. Turtle Creek, which had held above 5%, filed a 13G/A in May showing its stake had slipped below that threshold to 4.99%. As always with these disclosures, stakes are as last filed and holders who drop below 5% may not file again. FMR (Fidelity) added 1 million shares in the period to September 30, a notable build for a holder of its size on this name. Insider data shows only paired transfer transactions by the company itself in August, with no net change in position and no open-market buying or selling by named executives.

The stock has essentially gone nowhere over the past week, down 0.67%, while the closest peer on the correlation table, TNC, gained 9.3% and JBTM added 9.0%. That divergence echoes the peer-lagging dynamic flagged in earlier notes. ATS is up about 1.8% over the past month, a modest recovery but still well short of what comparable industrial automation and machinery names have delivered. The earnings schedule shows an event today (November 4), which will be the most immediate reference point for how the market reassesses the gap between the current price and the analyst target consensus.

The key variable to watch is how the quarterly print lands against the earnings yield and EPS revision backdrop, particularly given the contrast between strong 30-day momentum scores and a 90-day trend that has deteriorated sharply.
