TRI Falls 9% on Earnings Day as Woodbridge Watches From Above

Thomson Reuters posted its sharpest single-day drop in recent memory on November 3, falling 9% to C$155.07 after reporting third-quarter results, leaving the stock down 5.2% on the week and erasing a substantial portion of the 22% rally that had built through October.

The earnings reaction is the dominant fact this week. Shares shed 9% on the day of the print, a move that compares poorly with the August quarter, when TRI fell 8.5% the session after Q2 results and then lost a further 6.7% over the following five days. That back-to-back pattern of post-earnings weakness is worth watching. Peers largely avoided comparable damage on the day: BR fell just 0.25% and ADP dropped under 1%, while VRSK and EXLS each slipped less than 1%. WKL was the worst performer in the peer group at minus 2.3%, but none came close to TRI's move. The underperformance is not a sector-wide story.

Short interest and borrow conditions are, as flagged in earlier coverage, not the main event here. Short interest is running at 0.62% of the free float, unchanged on the week. Cost to borrow is a modest 0.83%, and availability is wide at 280%, meaning there are roughly 2.8 shares available to lend for every share already borrowed. The lending market is loose, and there is no mechanical pressure on shorts from the borrow side. The ORTEX short score of 40.3 sits in the lower third of the universe, consistent with a stock that is not under meaningful short-side attack.

The ownership situation remains the most structurally interesting angle. The Woodbridge Company, the Thomson family vehicle holding 70.7% of shares, sold roughly 1.5 million net shares across August at prices in the C$143 to C$150 range. Those sales happened well below the C$170 level where TRI was trading before the earnings release, and are now closer in price to where the stock has fallen back to. Thomson Investments Limited, a related family entity, holds a Schedule 13D on the register, last amended in April 2026 at a 70.56% stake. That filing is now more than six months old, so the precise current level is as-last-disclosed. The 13D designation here reflects control rather than activist agitation, but its presence on the register is a material disclosure fact. What is notable in the wake of the earnings drop is that Woodbridge's August sale prices, once looking like a missed opportunity given the subsequent rally, now look considerably less mistimed.

Valuation multiples have compressed sharply with the price move. The PE multiple has pulled back roughly 2 points on the day to 23.3x, and EV/EBITDA has dropped by 1.5 turns to 14.8x. Both are lower than a week ago, though the PE remains elevated versus a 30-day ago reading that was about 3 points lower. The dividend score ranks in the 93rd percentile, reflecting the special cash distribution announced in May. The EV/EBIT factor ranks in the 21st percentile, a persistent signal that the market is pricing in a premium that earnings momentum alone has not yet validated.

The next earnings event is flagged for November 5. Whether the market treats that as a correction or a continuation of the post-results slide is the key question the data leaves open.
